E520 Overheating 60 degrees idle 90 degrees under load

Hello all, I have had my edge E520 for quite a few years and now I believe that it may be thermal throttling games and applications etc.
At idle it runs at around 50-60 degrees Idle, and under load it can reach anywhere upto 93-4 degrees Celcius.
New compound has been applied bi-annually on this latop for it's whole lifetime. Is the heatsink no longer doing it's job? It's dust free. The fan seems to working fine on the heatsink, so I don't know where else to look at.
Cheers, Matt.

Well you should not count those in the power supply. Typically to balance you would want to have the same volume of air coming in as is going out. So if the 120's are both the same and both 80's are the same then you would get better airflow having an 80 and a 120 on intake and then repeat on the outtake side. Ideally then if you have a fan controller you would want both 80's chained ton one control and both 120's chained to another. That way when you controil fan speeds you will stay balanced. Note though you need a good fan controller to do this and you will have to check ratings to see if you can tie the fans together without overloading the controller.

X220 - What's your CPU temp under load?

Running SC2 for a few minutes and my CPU was sitting at 92 C consistently (i5 2520). Yikes!
What temperatures are you getting under load?
43C idle.

no not really, it seems the problem only came after the recent BIOS update. I will have a look at this issue when i have more time on my hand.
When running on battery saver mode, the temperature drops to 45 degrees, which is good as this is the setting i use most of the time.
P.S. The ambient temperature in Australia is more than 30 degrees celsius, so that could also contribute to the issue of overheating.

Freezing under load after Zalman 7000A installation - help!

I built a K8N system over the summer using the stock AMD HSF. Yesterday I decided to install a Zalman 7000A to quiten the system and to run a bit cooler.
The installation was relatively straightforward. As usual removing the back plate was a pain. The main concern was that the thermal pad used on the stock HSF was so strong that, despite twising to break the seal, still lifted the CPU out of its socket. All the pins looked fine and it went back in OK.
After re-installing the motherboard and connecting all the cables, system booted fine with no apparent problems. Temps looked a little better and perhaps a little quiter. Runs normal office apps ok.
Testing SETI@home to load the system, the temps rose up to mid 50s and the fan increased speed, and then the system froze (screen was frozen, no keyboard input). Booting into Fedora linux showed the same problem, idles OK, but running a numerical fluid simulation locks the system. The highest temp I have seen with Core Center is 61C (this is with BIOS 1.44)
A bit more testing showed a slightly strange behaviour from Core Center. The processor speed was fluctuating, with the FSB increasing so that at some brief instances it was reporting 2750Mhz.
I have previously seen this but small momentary increases from 2010 to 2100 or so.
So how to narrow down the problem:
have I damaged the CPU or motherboard during the backplate/HSF removal?
have I forget to connect something somewhere?
is there a problem with the Zalman installation so that the CPU is overheating (too little thermal grease)?
should I go back to the stock HSF
thanks

update on progress...
re-installed the Zalman heat sink. I very carefully cleaned both surfaces with cotton buds and methylated spirits (ethanol+10%methanol + purple colouring), then a dry screen wipe. A small, grain of rice size, blob of zalman thermal grease in the middle of the heat spreader. As in arctic silver instructions, rotated hs a few degrees to make sure it spreads and screwed tight carefully.
Initially looking good, although temperatures were pretty much the same as the stock HSF: idle with cool'n'quiet at 1000Mhz 33-35C, under load at 2010Mhz creeping up to 52-53C. I used Corecenter to manual hold the fan at full speed (2600rpm). Ran set@home for 10 minutes, and I was just about to kill it, satisfied that I had fixed the problems, when the screen went blank and the machine started beeping! (I had never previously seen this, only lockups with the screen frozen).
Later I had one other screen freeze, but this time the temperature had not risen above 45C.
I have BIOS 1.44 which is much better for temps than the BIOS is was shipped with, but I still do not really trust these measurements.
I am pretty sure the Zalman heat sink is installed properly - my only slight concern was the use of methylated spirits to clean it.
Looks like I will go back to the stock HSF over the weekend.
thanks for the help

W520 corei7 2720QM - 1 core is throttled under load!

Hi all,
I've been using my w520 for almost 2 years. It ran really great until recenty (these 2 weeks), I noticed that the core 2 & 3 constantly ran 20 degreer higher than core 0 and 1 under stress (i.e. wPrime) - please see img1 below as the screen shot of CPUID that shows the temperature under load.
In HWiNFO64 (img2) also shows that the core 3 was THROTTLED under stress.
All cores look fine after wPrime finished (img3).
Here's the configuration: corei7 2720QM, 1000M, 8GB ram, 500HD.
I just updated the bios to ver 1.38 in December, I'm not sure whether this is the cause of the 1 core throttle or not.
Has anyone experienced the same thing? Or does it sound like a CPU failure to you?
Thanks!!

Ok, I've reverted the BIOS back to ver 1.36 and then 1.32, the same throttling is still happening when running wPrime. Core 2 and 3 are consistently 20c higher than others when under load ...
I recall that the temperature on all the cores under load was like 85c max before ... and the machine was able to complete wPrime 32M under 10s, now it takes >11s everytime due to the throttling.
I've called Lenovo support 2 days ago, they said their safety team will contact me as it sounds like an overheating issue. However, i still haven't recevied any call from them ...
Can any tech. support from Lenovo help on this issue please?
Thanks!!

GTX 760. Too high temperatures under load?

Hello,
I have just bought a new machine with a MSI GTX 760 Gaming card inside. I am not really sure if temperatures I'm seeing are OK.
The card idles at 32-33 degrees Celsius. This should be just fine I think. However, once I run some benchmarks or get into a game, the temperature rise to round 80~81 degrees and in most cases stabilise at that mark. Is this normal?
Most of the reviews I've read of the card so far show far lower temperatures under load so I started to be a little worried.
The above temperatures show under default MSI Afterburner fan profile. I haven't touched the card OC-wise, these temperatures being the main reason.
If I manualy set the fan to constant 70% I do get a significant drop in temperatures. Under load the card now reaches 69~70 degrees.
I know there are many factors involved here, so I provide some more info about the machine itself:
Seasonic SS-520GB PSU
Intel 3570K with Corsair H55 cooling
GA-Z77N-WiFi motherboard
Kingston HyperX, DDR3 2x4GB 1600MHz RAM
Bitfenix Prodigy case
1x120mm fan at front, intake
H55 rad + 120mm fan intake, also at front
1x120mm fan at rear, exhaust.
Any advice would be highly appreciated!

No need to worry. the Maximum GPU Temperature of GTX760 is 97°C (http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-760/specifications) so your card is far from that mark. It is in a fine rage.
Temps strongly depend on the individual systems so you can't expect to get the temps any reviews listed. Individual temps might be lower or higher depending on the airflow in the case, other heating components, the fan profile of the current vbios, the applying of the thermal paste by the factory and so on.
As your case intakes hot air through the H55 that might be a reason for slightly higher temps. Also you have two times more intake than exhaust of hot air what can also increase temps. Furthermore you have a very small case so heat tends to stay where it was generated which causes components to heat up even more. In this situation your gpu temp is brilliant. Just game and be glad.

Cache and/or Connection problems under load

I have a Kodo web app that's been running just fine in
production for many months now. However, recently the web
traffic has shot up by a huge amount, literally overnight.
But unfortunately, it's caused the app to fail very ungracefully
under the strain.
It's been a crazy few days, and I haven't been able to do
very much analysis because of higher priorities. But from
what I have been able to gleen, it now looks like Kodo is
the most likely culprit. From what I've read in other messages
here, it appears others may have been experiencing similar
problems.
My environment: Redhat Linux 8, Postgres 7.3.4 with the
included JDBC3 driver, Apache 1.3.x, Tomcat 4.1.x and the
webapp connector. Similar behavior was seen with Apache 2.x,
Tomcat 4.1.x and the JK2 connector (that was on the new machine
I setup to handle the new traffic, which, of course, died the
night before).
As I mentioned, this app has been running reliably for
months with no problems. But when placed under heavy load,
it appears to get into some sort of pathological state where
it slows down dramatically (asymptotically?) to the point where
it's effectively locked up. In one case, where the app was
left running for several hours in this state, requests were
taking 90 minutes to complete (normal is 1-5 seconds).
From what I can deduce, there seem to be four things
going on, three of which have been mentioned in recent threads
here:
1) Excessive memory consumption. When the app is
operating normally, I see fairly flat memory usage for
the JVM process. Under load, the JVM steadily expands
until it hits its heap limit. I've gotten OutOfMemory
exceptions with a heap size of 350MB, which should be plenty.
2) Level 2 cache locking issues. I've seen dozens of
threads waiting on a lock in the DataCache code. Not sure
if there's a deadlock happening here or just that the
threads are waiting on a lock that's being held for a long time.
3) Database Connection leaks or contention. I see threads
spinning in the DataSource code trying to get a connection.
I also see dozens of connections from the Postgres side which
seem to be sitting idle, but in the middle of a transaction.
When things get bad, I also see exceptions being thrown because
of timeouts waiting for a connection to become available. It's
a web app, PMs should not be tied up for more than a few seconds.
4) CPU usage pegged or nearly so for the JVM. I suspect
this is related to #3. Something very bad is going on here.
If I stop all inbound requests to the JVM when it's in this
bad state, it will continue to burn CPU at 90%+ for a very
long time. I think it will eventually finish what it's doing,
but I haven't had the luxury of waiting for it. It's definitely
not a linear slowdown proportional to the load.
Attached are my kodo.properties file and some thread stack
traces along with some comments. Any advice would be greatly
appreciated. This is not a complicated app nor am I doing
anything unusual. It doesn't seem logical that Kodo could
breakdown so dramatically under load, so I'm hoping it's some
sort of interaction thing that I can work around.
Thanks.

Please read prior posts regarding level 2 cache. It is unusable under stress
as far I am concerned. Basically entire cache gets locked on any database
read. Makes it very unscalable
Are you using 2.5.3? It will request a connection from a pool every time it
resolves reference to a PC even if it is cached in PM and therefore Kodo
does not need to read any. As result if you iterate over 100 objects in your
query and for each object resolve reference to another object (always the
same) kodo will request 100 database connections from the pool (and note
they issue rollback on every time they return a connection to the pool so
getting connection might be fairly expensive)
In conjunction with level 2 cache contention this causes application to go
into a stupor.
Try to go back to 2.5.2 (or may be 2.5.4 they promised in the near future
with a workaround) or use "persistent-manager" connection retention if you
discard PM after each HTTP invocation - it will take care of connection
pooling issue. As far as L2 cache I was unable to find any work around so
far - see if you might be better of without cache. You might if your object
graph is not very complex

With cahce enabled, 2.5.3
Here the app had recently slowed down and then effectively locked up.
There where many outstanding web requests that were not receiving output.
At this point most threads seemed to be waiting at the same location.
There were a large number of active database connections and most of
them had open transactions (according to pg_stat_activity). The app
was not responding to any web requests.
It would seem that db transactions had been started, then the thread
got stuck for a long time on a synchronization lock in the cache lookup.
Below are two randomly chosen thread stack dumps.

while running slow, 2.5.3
At this point, the app had been running several hours normally, then
apparently slowed down and locked up while I was away. When looking
at the app threads and database activity, everything appeared idle.
No transactions seemed to be open in the db. But the app was not
behaving normally. Web requests that did not make use of JDO worked
fine (but slow). But requests that hit the db either blocked or were
very slow to respond.
Looking back at the log, there had been a large number of requests
that threw exceptions because they could not get a connection within
five seconds.
Most threads were idle, waiting on read, but some were in the state
shown by the following two stack dumps. Unlike the cache threads above,
they did not seem to be waiting for a lock to be granted, they seemed
to be spinning in the connection management code. Apparently trying
to get a connection. I suspended and resumed the same thread repeatedly
and it always seemd to be doing the same thing. Single stepping was
very difficult because the debugger was slow to respond, apparently
because of other threads also busy spinning.
Postgres indicated that there where lots of connections open and
that they were all idle, so there should not have been a shortage
of connections in the pool. There are two mysteries here: 1) why
can't this thread get a connection? and 2) Why is it busy spinning?

With cache disabled 2.4.3
This run was an accident. I inadvertently ran the app with the older
2.4.3 version of Kodo, with the cache disabled. This one got into trouble
almost immediately. It also seemed to lockup with lots of opentransactions
in the db. It's also interesting that these two threads also seem to be
hanging around the same method as in 2.5.3.

925X NEO Plat reboot under load

Hi all,
After 3 nights trying to find what is wrong with my config, my last hope is that one of you will save me
I recently received my new MB and was quite happy. My problem is that when I start XP SP1, it works ok for a while with a CPU idle at a 70°C temperature.
If I start 3DMark2005, computer works for few minutes, cpu fan speed up and PC crash. On reboot most of the time it freeze with all but the second diagnose led green: ie G R G G.
Does anyone knows what may be the reason.
Moreover, even if with bios I see a high CPU temperature, the CoreCenter complain about an unsupported MB, so no way to check CPU temp under load.
I Flashed my Bios to v1.3, changed PSU from a 350W enermax to a 550W Qmax, tested with various memory configurations, I'm desperate
Config is :
925X Neo Platinum
P4 3.4GHz 550
4x512MB PC4300 DDR2 Twinmos
Gigabyte X800XT 256MB
2 SATA HD, 1 IDE HD, 1 IDE DVD
550W Qmax
I'm waiting for your comments,
Regards,
Judgef

Hi,
For cpu-temp monitor - Download and install Speedfan
http://www.almico.com/speedfan.php?ExtraId=1138
To get “auto” cpu temp monitoring in tray, when windows starts –
Go to start / program / find speedfan exe-file (icon) and drag & drop it to autostart.
Then go to speedfan – configure – option – start minimized.
Then configure – check the “right” temp /fans / voltage sensors.
For cpu stress – Download and install Prime95 ( torturetest )
http://www.mersenne.org/freesoft.htm
Assuming cpu and heatsink are correctly mounted – do you have an overall good airflow in the chassi ( incoming air in front / out in back + sidepanel fan ?)
Also regarding overall stability.....
At what voltage is the DDR2-memory settings in bios ?
Have tried increase voltage some ?
Tested Ram for errors ?
http://www.memtest86.com/#download0
You´ll need a dos disc.

Computer very unstable when under load

hi,
some weeks ago i had problems with turning on my computer. the problem was, that the psu was dead. so i got i changed in the store where i got it, and the computer is working fine again. but it simply restarts when under load, like when im playing games. after a short time it restarts without a warning
hope some of u know what to do with it...
greetings from Denmark
MSI KT3-Ultra,
256MB Samsung PC2700
Inno Gf4 ti-4200 64Mb
IBM 20,5GB harddisk(Deskstar 60GXp)
Xp2000+

as I was the one that built the initial computer i might aswell answer:
Temps: 32 idle 45 under load
HSF: Volcano 7
The initial psu had no problems running the system stable, after it died, and was exchanged to the excact same model at the store the problems started. I suspected that something had gone with it(maybe some component on the mobo,cpu etc?) and if there was something else u guys could maybe help him out.
Well if i remember corectly the 3.3V is a mere 25A and the 5V is 35A. Yes it's on the weak side(btw. i did not suggest this PSU) but after it worked well before i do not believe it is the cause of his symptoms.

Failure under load

When under load my system is extremely unstable and im not sure why, its been a year of trouble shooting and still no luck. Here is how it all came about.
Its sort of hard to explain, basically the computer runs perfectally aside from slightly low scores in the 3d marks but i can live with that. Then when i try and play games the system becomes unstable. When i first built the computer almost exactally a year ago it used flash blue screen and restart when idle in windows at random intervals and since all the hardware was very very new and there didnt appear to be any reason for this i assumed that it was driver conflicts. At this time all games ran fine and no reboot problems occured when gaming. The over the past summer i got battlefield 2. When playing it the computer will restart at random intervals sometimes hours sometimes only 10 or 20 minutes. It locks up the sounds goes from skipping in a loop to resuming back to skipping for 30 seconds or a minute then it just restarts. Upon returning to windows i get a "Windows has recovered froma serious error" message and when sending the report it comes up as a driver problem or hardware issue with nvidia graphics card. After trying almost everything i could think of including every combination of every set of drivers and countless windows installs i decided it could be my video card. So i RMAed it and MSI sent it back with a pass. Back to square 1. So no my computer runs 100% stable in windows but as soon as i start gaming it only lasts an hour maybe nomally less before cash reboot.
Also when in windows if using an intensive program (the only one ive found so far is Pro Engineer) it will drift in and out of responsiveness. For example i will be drawing a 3d Model and the mouse will stop responding but keep moving, then the mouse will freeze and the computer will be fullylocked up, then it will unfreeze the mouse but remain unresponsive. This will continue for a couple fo minutes then it will resume and i can continue my work but 5 minutes or less later it repeats. The mouse is not just unresponsive in the application in question but entirely in windows.
Any suggestions would be greatly appreciated.

Error caused by a video device driver
Thank you for sending an error report to Microsoft.
Error report summary
Error type    Windows stop error (A message appears on a blue screen with error code information)
Solution available?    Yes
What does this error mean?    You received this message because a device driver installed on your computer caused the Windows operating system to stop unexpectedly. This type of error is referred to as a "stop error." A stop error requires you to restart your computer.
Cause    A video adapter device driver
Computer symptoms    A message appears on a blue screen with error code information:
STOP 0x000000EA THREAD_STUCK_IN_DEVICE_DRIVER
- or -
STOP: 0x100000EA THREAD_STUCK_IN_DEVICE_DRIVER_M
Action for you to take
We have analyzed your error report and there are two solutions for this problem for you to choose between.
+ Solution 1: Install the most current driver for your video card
* Go to the Microsoft Update website to see if there are any updated drivers for your video card. A driver is software that enables hardware or devices (such as a printer, mouse, or keyboard) to work with your computer. Every device needs a driver in order for it to work. If there are any drivers listed, you should install them.
* If there are no updated drivers at Microsoft Update, and you know the manufacturer of the video card, contact the card manufacturer's product support service for assistance.
* If there are no updated drivers at Microsoft Update, you don't know the name of the manufacturer of the video card, and you need more help diagnosing and resolving this problem, contact your computer manufacturer's product support service.
+ Solution 1: Most recent drivers
+ Solution 2: Manually decrease Hardware Acceleration for your video adapter
This is the error message i get from microsoft and i tried both of these things and they do not work. As for the sound i disabled it in the bios and tried still crash but it took longer. Now im using another card Audigy 2 value and it crashes less frequently.

WL server failed to response under load

Hi
We have a quite strange situation on my sight. Under load our WL 10.3.2 server failed to response. We are using RestEasy with HttpClient version 3.1 to coordinate with web service deployed as WAR.
What we have is a calculation process that run on 4 containers based on 4 physical machines and each of them send request to WL during calculation.
Each run we see a messages from HttpClient like this:
[THREAD1] INFO   I/O exception (org.apache.commons.httpclient.NoHttpResponseException) caught when processing request: The server OUR_SERVER_NAME failed to respond
[THREAD1] INFO   Retrying request
The HttpClient make several requests until get necessary data.
I want to understand why WL can refuse connections. I read about WL thread pool that process http request and understand that WL allocate separate thread to process web request and the numbers of threads is not bounded in default configuration. Also our server is configured Maximum Open Sockets: -1 which means that the number of open sockets is unlimited.
From this thread I'd want to understand where the issue is? Is it on WL side or it's a problem of our business logic? Can you guys help to deeper investigate the situation.
What should I check more in order to understand that our WL server is configured to work with as much requests as we want?

Thanks for a good explanation!
Linux server it's not in my competencies but what we have now is:
root    soft    nofile 3072
root    hard    nofile 65536
So the upper number is really big. As I understood it's a config for whole processes in operation system.
But I go further and find these numbers for our WL managed server.
cat /proc/23085/limits
Limit                     Soft Limit           Hard Limit           Units

Max address space         unlimited            unlimited            bytes
Max file locks            unlimited            unlimited            locks
Max pending signals       578455               578455               signals
Max msgqueue size         819200               819200               bytes

Max realtime priority     0                    0
Again it's only a config numbers. If continue moving in this direction I'd want to see the real numbers when the server is under load. So finding these numbers I would make an assumption that the issue is here. Don't you know is there a log file or history file where I can find a max open file descriptors for WL server?

Battery level dropping under load while plugged in

Hi all,
I'm, the otherwise happy owner of a retina Macbook Pro form July 2014 (with a 85w power supply)
I have the issue that, whenever my computer is under load and uses the discrete graphics card, its dropping power - even though the charger was connected.I know the discrete graphics card uses up more power, but honestly it cannot be true that if I play a game in high settings on the macbook (which only has a keyboard, mouse and charger connected in that case), then the battery drops... It cannot sustain itself or what? (I have never experienced this with any other laptop, so I hope for the love of God, this is not what to expect).
Also, just the other day, I was using 2x external monitors (with their own power supplies), and just watching a Twitch (videogame stream) in a browserwindow on one of the screens, and the charge started dropping, even while plugged in again -- it dropped maybe (a wild guess) 10% an hour or so.
The setup there was: I had iMessage open on the screen on the macbook - nothing else; I had a PDF displayed on the first external screen and I had a browser-window open with a video-stream on the second external screen. A mouse, keyboard, powersupply and 2x videooutputs (1x HDMI, 1x DisplayPort), was connected to the macbook at that moment...
I mentioned that I couldnt play anything with high settings, or watch a videostream while using external monitors without draining the battery power to a friend that has had a few macs - he had note experienced it before, and told me to post in here (After we agreed that since the external displays had their own power supplies, they shouldn't be dealbreakers). I'm hoping you can help me shed some light on the issue and help me. If something might need to be sent back to Apple for replacement, I'd rather do it before I personalize it too much.
Thanks alot!

Thanks for the answers I see.... A shame since the 85W charger is by my understanding the highest wattage one Oh well, thanks!

Why has my mail started storing under Load More Messages. I'm now unable to access my mail messages.

This is my basic, first start, recommended "fix" when these types of weird, unexplained things occur on the iPad. Give it a try. After you reboot, go back to the mail app and see if the messages will load.
Quit the mail app completely and reboot the iPad.
Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Dv8315nr drops to battery while plugged in, especially under load

Have the dv8315nr and it keeps dropping to battery while plugged in, especially when the PC is under load, such as games or using CD drive. The power block is ok, it has been tested with other power blocks and the issue still happens. If you unplug the power at the pc and plug it back in, it will (most of the time) go back into a charging state. I sent to hp while under the extended warranty and they sent it back with the diagnosis of "battery was bad, needed new battery".....and it worked ok until just out of warranty then started again.
I don't think it's the battery, since it happens with or without the battery in place (of course it dies completely when the power drops w/o battery in).
Has anyone experienced this and if so, have a method to fix it? I suspect there is a hardware problem with the power supply in the laptop.
This question was solved.

It sounds like the beginning stages of a bad power jack. That is the place where you insert the AC adapter into the laptop. The problem is very common and requires that a new jack be installed. Fortunately for you, the dv8000 has the power jack as a separate plug-in module...it does not require soldering just removal and replacement.
Here is an internet ad for a company that does the repair. I am not suggesting you hire them but they do post some nice pictures of the internal workings of the dv8000 series so you can understand what I am writing about. The repair job is only modestly hard; not nearly as bad as if soldering were needed. The part is readily available.

JDK 1.3.1_08 Under load on linux (RH7.3)

I have been running JDK 1.3.1 on linux under a development environment for quite a long time (2+ years) without issue, running a large Java application cinsisting of EJBs, and Web apps being run by BEA Weblogic. In an effort to cut costs we are migrating to linux for our production systems.
During the testing phase of running our applications on a dual-SMP Xeon based server with 2 GB of RAM we had no issues. However under load the java child processes (threads to the JVM) are getting very low priorities (15-19) and have a status of "SN" sleeping, and low-priority. If you run pstack on the PPID of the java processes they seem to be 'stuck' in nanosleep.
Does anyone out there have experiencing running large apps under high load on linux platforms?

had no issues. However under load the java child
processes (threads to the JVM) are getting very low
priorities (15-19) and have a status of "SN" sleeping,
and low-priority. Every Linux JVM that I know does not use native thread priorities (nice levels) at all, so if you are seeing child PIDs at the 15-19 range, someone most likely started the JVM at the exact same nice level. How many runtimes do you have running? What are your 5, 10, and 15 minute load averages? Are they under 2.0? Can you start your runtimes at a lower nice level?
Does anyone out there have experiencing running large
apps under high load on linux platforms?The `S' you see w/ ps is not particularly indicative that its stuck in this queue, just may be waiting for IO. Adjust your runtime nice level to 10 and under if your load is high and you have a higher IO priority runtime (as you have a dual-proc system).

MSI 6970 Lightning-Bouncing GPU Core clock in GPU-Z under load

Hi,
When doing some stress testing with furmark, I noticed the GPU Core Clock would bounce around between 600mhz-940mhz under 99% GPU Load. Is this normal?? I figured it would hold steady at 940mhz under load,not really sure why it's bouncing around.
Thanks!

Figured it out.. had to change the Power Control settings in CCC to +20%... maintains 940MHZ now
