Understanding CPU-Z
About a month ago I built my first computer. All seems to be working well, but now I wanted to look at things more closely. I downloaded CPU-Z but can't really find anything on what I should be seeing as results based on the set-up I have.
Right now I don't want to overclock anything, just want to understand what these things mean and see if they seem accurate. For what it's worth, the system seems to be running a bit slow as of late and I've also had freezing problems in Doom3 which I did not have when I first installed the game. I think the only think I've done is turn on Cool n Quiet in the BIOS.
When I open core center and CPU-Z, it shows my multiplier as 5X. I'm almost positive it was 10X before I turned on Cool n Quiet. I don't know which is better. Below are the results from CPU-Z. Perhaps someone can point me a direction to learn about what these things mean.
CPU-Z
Core Speed 1004.9
Multiplier x5
HTT 201 mhz
In Core Center FSB shows as 201 and VCore as 0.
EDIT
I just turned off Cool n Quiet.
Multiplier is now 11.
Core speed shows as 2210.8.
HTT is still 201mhz.
I think once I have an undertsnading of what these things mean, I will understand which is better.
korey,
first off, to monitor things, i wouldnt use core center. i havnt confirmed this but other memers in this forum have said that it is not that accurate in reporting things and i dont doubt them. use either motherboard monitor or speed fan. a simple google search will dig them up. cpu-z is a good program to use, so keep on
as for an explanation of what the numbers cpu-z is spitting out, the core speed is the speed that the cpu is running. to derive this, the FSB is muliplied my the multiplier(how many times faster the cpu is running in relation to the FSB). so when you turn on cool and quiet, the chip is running less than 1/2 of what its full potential is, and that what is killing doom 3 for you. when cool n quiet is off, the cpu is going full speed, doom 3 is going well.
idealy, cool n quiet kicks in when you are doing light stuff like email, web surfing, using word, stuff like that. it lowers the cpu speed, voltage, and the cooling fan on the cpu to keep heat and noise down. when you go to a high cpu useage prog (doom3) it kicks the voltage, cpu speed, and fan speed up to normal so you have the power to run the program.
in your case it seems that cool n quiet is staying in that low state. the cool n quiet implementation on this board seems to not be as mature as it should be to opperate without notice from the user. hell, in mine the thing doesnt even work!!! ive tried everything. so, my advice is to keep it off until we know that it is stable and able to work flawlessly.
if you need further explanation, feel free to post more, ill keep an eye on it and there are many more people that have infinitly more knowledge in this area on this board.

Too much exclusive CPU time counted at swapcontext function
Hi,
I'm using Sun Studio Express March 2009 Build, especially Performance Analyzer, and I have observed some hardly understandable CPU times measured at swapcontext function of libc library.
Here is my machine spec.
Two-way Intel E5320 processors with 16GB memory
SUSE Linux Enterprise Server 10 SP1 (x86_64)
My program consisted of 8 threads (pthread), and around a hundred of user contexts (coroutines or fibers) run on every single thread. I'm using makecontext/swapcontext for creating/scheduling user contexts on threads.
I'm using both Sun Studio Performance Analyzer and Intel VTune Performance Analyzer.
My problem is that performance analyzer reported about 20% of total CPU time as the exclusive CPU time of swapcontext function, while I couldn't find as many HW event samples related to swapcontext by using VTune.
To narrow down the problem scope, I made simple test program, and I reproduced the problem. I attached the test program generator written by bash script at the end of this message.
I generated the test program with following command.
% bash code_gen.sh 8 128 100000 1000
Then, you can get the test program, which consists of 8 threads with 128 user contexts at each threads, and 100000 times of context switch at each user context.
In my system, Sun Studio Performance Analyzer reported 328 seconds of exclusive CPU time at swapcontext out of 463 seconds total CPU time (CPU Time of <Total>). Briefly, swapcontext consumed about 70% of total CPU time.
However, according to VTune sampling, both libc-2.4.so and vmlinux-2.6.16.46-0.12-smp consume only 8% of total clockticks.
It's too large gap between Sun Studio and VTune.
Have you seen this kind of problem? Do you know why this mismatch happens?
Or how can I estimate actual swapcontext cost?
Thank you for reading my post, and I'm looking forward to some hints about my problem.
Colin

Hi,
As per my understanding CPU patches are released every quarter for each version & realease of oracle database.
I am using Oracle 10.2.0.3 on IBM-AIX 5.3 (64 bit).
I checked on below link of metalink.
Patches & Updates -> Oracle Server/Tools -> Latest Patchsets -> Latest Oracle Server/Tools Patchsets -> Then selected oracle database and OS version -> Patch Type selected as Any -> Classification selected as High/Security -> Go
But the above gives me no CPU patch list!!!!
So is it no mandatory that each & every quarted we will get a new CPU patch from oracle? Or am I doing any mistake in selection above?
Thanks in advance.
Best Regards,
oratestHi Srini,
Thanks for your reply.
As per the link doc, the primary support for 10.2 has been ended on July-2010, and the extended support will end on July-2013.
And as you mentioned that CPU patches are released in extended support as well, so as of now I must see CPU patch in metalink for my database release (10.2.0.3). But I can not see any CPU patch for my version, release??
One more thing: As per my understanding CPU patches comes under High/Security patch classification, am I right?
Best Regards,

Hi, back in the days I wanted a 12" iBook but couldn't afford one, last autumn thought I decided to get a Macbook Pro, the update came and...
.. it had 128MB vram.
I want to use dual screen and maybe even occasional gaming, I couldn't decide if this where sufficient for my needs or not so I waited for the june update.
The mid-07 MBP arrived and, it had 128MB vram AGAIN!
Why oh why Apple? Oh, don't answer that, it's because you're in bed with Intel and want to force feed us useless highest end CPUs. But all I care for is the VRAM, why do I have to pay a ****-of-a-lot for a 1/11th faster CPU?
Anyway, I tried to decide if I should "bit the sour Apple" and get the mid modell or just get the low one because that one is much more price worthy. A few days ago I ordered the low end one.
But then I've seen on barefeats that he says that a 30" ACD display would use 128MB vram of the 256MB vram modell, are vram always splitted between displays in OS X?
You see, if the extra 20" 1680x1050 display only use 1680x1050x(3 or 4) bytes that is ok, maybe even if it's double buffered (is it?), because then I will probably have like 100MB vram left for all my windows and for desktop usage that is probably ok. But if the vram is shared between displays and my 20" which I will use most only get 64MB vram that's quite low.
I know I can turn of the sleeping capabilities of the MBP and shut the lid and only use one screen but that's a quite lame solution.
I hate how Apple does this, and it seems to worry a lot of people. Some get the more expensive modell and hate that they had to do it, some doesn't, and some don't buy a machine at all .. I would probably have stayed in the last crowd.
256MB vram can't have cost them many tens of dollars, why not have that in all modells? Why is the middle one even needed? Just make 2.4GHz CPU and option in that case.
Anyway, does anyone know how much vram my screen will have available? Will 128MB work for me with all the regular desktop apps I will have running? Or should I really go with the 256MB one? The tricky part is that my MBP might be shipped today or similair.
I've called Apple support three times but noone of them knows how this works so they aren't for much help.
(Dell vostro 1500 sells here in Sweden for less than half the price of the mid MBP and comes way more balanced, you can even get a 1680x1050 screen. Sure it has 2.0GHz CPUs or whatever but I don't care about that. Where is the old "omg MHz myth"-Apple? Please understand CPU speed isn't everything. Instead of leading the MHz myth fight it ;D, start calling the CPUs T7300 and so on aswell ;D)Hi Johan, actually the VRAM used by OS X is likely to be quite a bit more than just your screen resolution multiplied by 3 or 4, since each open window is composited offscreen for the shadow effects and for things like zooming (Ctrl-Mousewheel) and the "Genie effect".
I'm pretty sure the total VRAM isn't divided in half for each of the two displays though, as it will be allocated from the video driver on an as-needed basis. In practice, with both displays active and a few windows open, you should still have maybe 80-90% of your VRAM available for applications.
Games and other VRAM-heavy applications are a special case as these will typically use as much VRAM as you can give them, and swap out to system RAM via the PCI-X bus when they need more (and unlike swapping to disk, swapping into VRAM from system RAM is still pretty fast). -
Hi All,
Can you please educate me on below things. Also, please correct me if i am wrong
1.
db_writer_processes controls number of db writers that are been started when instance is initialized. So, once DB is up lets say we have 6 dbwriter process then your buffer cache is splitted in 6 working data sets. Can you please explain what is this datasets are ? or may be if i am wrong .
2.
If so this is true how can we find that which dataset is used by which dbwrite processes. I mean how to find one to one mapping for say 0x address- to 0y address is been worked by dbwr1 process and so on. how to find this
3.
If we have multiple buffer cache like db_16k and db_32k then how do we map this.
Reason behind this we are using 12 dbwriter process for we have 12gb of sga and 10gb of pga. Some time we are getting buffer busy waits. So, need to find that we are using multiple buffer pools. So, if it is from there then i can suggest management to use only default block size and not multiple. I already know that multiple buffer pool have overhead of managing one more memory structure so need to investigate and learn from you.
My idea is to reduce this and then start adding processes if necessaryHi Jonathan,
Thank you very much so here are the things which we can conclude from this. Please correct me if i am wrong as i am new to this whole thing.
1.
Excessive db writer processes can be overhead due to each working set requires it's own db lru latches.
2.
Excessive db writer processes can slow down I/O due to they need to acquire CPU and then run. But one question here is does all db writer process simultinouses compete for cpu or it waits for one to complete and then go to other cpu. As, i can understand cpu uses serialize mechanism but lets say we have 12 dbwriter among one is writing using one cpu and other cpu is free. So, other process can move to that or db writer process is also serial ?
3.
Also, this can lead to wrong buffer waits situation as we can have free buffer in other sets and in one set it won't and process acquire that dbwriter so that it will post this wait event but actually we have other free buffers available. How to find this as how many buffers are available, dirty or in other state for each working set ?
4.
NAME TYPE VALUE
db_32k_cache_size big integer 32M
So, it means that for 32MB scanning of memory we need 12 data working sets or this 32k block size dbwriter data sets can be used by 16k also ?
And here is the output from our environment

Have tried advanced dram config with values 5-5-5-15.
5 voltages on cell menu all grey, unable to change.
Tried disabling spread spectrum, same results.
I'm out of ideas, and so is google given the search terms I've tried. Suggestions?"Yes, P6N Diamond on the box and printed on the mobo."
kk, just checking another possibility
"Interesting, that compatability list claims quad core support but then doesn't list any quad core cpu's I recognize."
For detailed CPU support, you should consult with CPU Support list.
Also 65nm Quads are supported, when mainboard were released there was no 45nm Quads yet. -
Understanding statspack report(CPU time in top time events)
Hi,
I am using oracle 9.2.0.8 RAC on SUN solaris platform.I am trying to understand my DB statistics using the below statspack report.Can you please coment on the below report
My quetions/thoughts are:
1) CPU time is in the top timed events,Is that eman some need to do with CPU increase.Was CPU bottleneck?
2) Parse CPU to Parse Elapsd %: 80.28 .Is this means I am hard parsing most of the time.How can identify which queries doing more hard parses.what is mean by% Non-Parse CPU: 98.76
3) Memory Usage %: 96.25 96.64.It seems to be there is too much memory usage.Can you elaborate this usage about what could be the reasons for this to happen
4) global cache cr request is coming in the top wait evetns and top timed events.Is there some issue with RAC?
5) can you please explain about 5 CR Blocks Served (RAC) and 5 CU Blocks Served (RAC) and Top 5 ITL Waits per
Your help is appreciated!!

user509266This statspack taken for 30 minutes interval.We have 16 CPU's.We never got ORA-4031 errors.It means you have 16 * 30 * 60 = 28,800 seconds CPU available during the interval but you only used 10,406. So you don't have a CPU problem.
For Statspack documentation, you can have a look to <ORACLE_HOME>/rdbms/admin/spdoc.txt, Metalink note 228913.1, Jonathan Lewis Scratchpad, books commended by Rajesh Kumar Yogi and also to http://www.oracle.com/technology/deploy/performance/index.html -
ORA-02393: exceeded call limit on CPU usage -- Concept Understanding is req
In our System CPU_PER_CALL is set to 1.5 Hours for Reporting Users.
I can see some query runs for 10 hours-15 hours and complete successfully and some queries fail exactly after 1.5 hours.
I want to understand what does CPU_PER_CALL Means. On what basis it calculates CPU_PER_CALL ( Fetch , Execute , parse). How a query is calculating time ?
With the same profile options some queries run for 10 hours but some queries fail after 1.5 hours.
Regards
Sourabh GuptaThe short answer is that different queries wait on different sorts of events. Let's assume that the only 2 wait events in the world are waits for CPU and waits for I/O (there are many other types of waits but most reporting queries will primarily be waiting for these two resources). If you have a query that runs for 15 hours but spends 14.5 hours waiting on I/O and only 0.5 hours on the CPU doing comparisons and/or calculations, the CPU usage for that query is only 0.5 hours. Another query might run for 1.51 hours and do 0.01 hours of I/O and spend 1.5 hours on the CPU calculating various aggregate values for that data. The second query would use 1.5 hours of CPU (and thus exceed your CPU_PER_CALL) while the first query would only use a third as much CPU.
Oracle profiles allow you to specify a number of different limits so that you can specify limits on CPU usage (CPU_PER_CALL/ CPU_PER_SESSION) or I/O usage (LOGICAL_READS_PER_CALL/ LOGICAL_READS_PER_SESSION) or a combination of the two (COMPOSITE_LIMIT).

Can anybody help me to understand the CPU usage logs
Hello community,
I try to find the faulty machine in our network, but I don`t understand the logfiles. We have many servers which normally work very fast and reliable.
But sometimes we have such a huge cpu usage drain on our server. Nobody knows where it comes from, so I looked in the vsphere web client and looked in the cpu usage logs.
Following you can see two pictures. One is from the main host. It shows only a cpu usage of a maximum of 45 %.
When I look on the vmware machines I can see a cpu usage of more than 150%.
This is something I completely not understand. How is it possible that the main host machine has only a 45% cpu usage and the clients are exploding?
I don`t have set a cpu usage limit in our resource pool.
The next thing is. When I look on the vmmachines, I can not identify the faulty machine. Because when one machine increases the cpu usage many others increase too. Whatever why.
Can somebody explain me the pictures below please:
Thank you for your time
PaulYou don't have any need to understand this code. The complication is due to the registry needing a fixed objectID.
You just need to know the methods of java.rmi.registry.LocateRegistry class. This allows you to start an RMI Registry inside your JVM and give it any TCP port number you like. -
[P67-GD65] OC CPU and voltage. After one year I still do not understand...
It is "provoked" by this fantastic post:
https://forum-en.msi.com/index.php?topic=157376.0
Quote from: Bernhard on 03-March-12, 19:06:19
My CPU is able to OC to 4,5 with all settings on Auto in the BIOS...
2500K running 4500MHz 1,367V on "Auto"? I can only dream about it and I am not talking about CPU but MB!
My 2500K is running 4500MHz with "int. overvoltage" option enabled but I have to chose:
1. set multi x45, CPU voltage to 1,340V, vdrop to auto - CPU-Z shows 1,384 running Prime - it`s ok IMHO, but no drop to low, idle voltage.
2. set multi x45, CPU voltage to auto, vdrop to Low - CPU-Z shows 1,424 running Prime -
or
3. set multi x42, CPU voltage to auto, vdrop to auto - CPU-Z shows 1,280 running Prime - it`s ok
I see from table that on 4100MHz Bernhard get (assuming "Auto") 1,352V! How? Maybe vdrop was set to "Low"(?) Heh... I get 1,408V with vdrop "Low" while running 4200MHz! It is the same as running auto OC Genie/Moron with button.
In other words... I do not know what is so special with Bernhard's settings to get 1,376V running 4500MHz on "Auto". I know that test was on Z68 and using multimeter but is it possible that voltage oc settings are so different (means broken) on P67-GD65 or maybe it is just a simple user error on my side(?)Quote from: Jack on 07-April-12, 23:31:00
Yes, that is possible and that does definately not mean something is broken.
"Definately" is a rather strange word in my opinion. Please, do not get me wrong it is (again!) just my opinion.
Quote from: Bernhard on 08-April-12, 00:20:36
I understand your question and possible frustration...
Frustration? No, no, no! I am rather happy with my gaming rig I just want to know, understand more.
So... Could You tell me your Vdroop setting? It is very strange that on "Auto" I get 1,280V (4200MHz, Prime blend, its ok) and You get 1,352V (IMHO too much without vdroop option) on 4100MHz. This is huge difference. Is it just a CPU batch difference? Mind You, when I switch vdroop to "Low" (I have only "Auto" and "Low" here) CPU voltage reading goes to 1,408V (4200MHz, way too much voltage!) testing Prime.
BTW: Older P67-GD65 bioses have Auto, Low and High vdroop settings. AFAIR Low and High was the same. Am I wrong? -

In years of setting systems right from the tsr80 4, 5.125 floppy,no hd's. I have came to discover that data is power from a +- scale. Managing this power for data is another thing. Cpu and components need to understand the scale and that is what the problem for most is. Core Cell, is a way of managing the voltages for power supplied to critical system operation and in the duriation of playing with your computer, the software gets confused, with the sorces of power supplied by the power pack. To use core cell correctley you have to disable power saving features in the bios also disable power saving features in windows itself other than turn off monitor. Next is making sure irq's and dma's are not conflicting even if windows say no conflicts there may be things. Check too see if usb is sharing a irq or a dma because the data is power and if they are sharing. the power will sometimes get a jolt and blow up the data and casue a" you know ",bsd or the dreaded illigal thing. System compatiably can be managed by turning down the fsb slightly lower than expected this will create a even data or +- source to address. Remember refresh rate's of monitor to clock speeds in video cards need the same care to power and compatiablity, the board itself,once all is set correctly your system will run like a dream. I got the LSR delta and I had problems but setting power for system operation fixed all problems and please make sure to load drivers for usb2 only if you use pci usb 2 complient devices or you will get problems. One last thing is a good power regulator or a power switching system is what a computer loves. This will supply a good steady flow of power to your power supply rather than zitter bits of uneven power. Have a good one im getting drunk now
It is always good to maintain all the date related fields in one table call it(Time dimension, calender dimension...), the reason for being said like this in obiee is for best modeling purposes. OBIEE best modeling approaches always insists on star schema with proper fact-dimension defined in the layers of the rpd.
All the time series functions like Ago, To_Date can only be used only when we you have well defined time dimension.
As you mentioned that you have some bunch of dates in your fact table itself, and I dont know if you can create a time dimension by adding a datewid or some thing to be your unique combination of the date.
If you cant do that then you have to join your fact table back to your fact table(Self join) itself for you to be able to do any kind of year over year analysis or period over period analysis. (Comparing between base period/year and prev period/year)
It all depends on your requirement and how we handle it. But for best practises purposes it is always good to have a time dimension to implement time series functions and to create a dimensional hierarchy for drill down purposes
Hope it helps
thanks

Panic(cpu 13 caller Crash. Trying to understand what is causing?
Ok,
so I have a Mac Pro 8 Core Mid 2010 running 32GB. For some time now I have been having crashes when I run Adobe Media Compressor. This only happens when I run a very heavy load. I have removed my ram and reseated, cleaned out the motherboard. I have also removed a GTX250 video card and I though the issue had went away but it came back. I have also reinstalled my software from scratch and buildt a new array with new HDD. I am guessing either a bad memory stick? or Processor? Or I am just stressing the system too much by renderring large files?
So here is the crash report I get.
Any ideas?

Huge CPU using : where does it come from ?
Hi,
I programm this beginning of game. It's prettty simple , a charachter which rotates following the mouse pointer. The problem is that this simple application uses about 66% of my Athlon 2200+ when I move the mouse.I don't understand , ok there are some mathematics operations and i use two images to do a clip effect , but that's impossible to do a game without that , that's nothing compared with a real game ...
So can you try to look at my code and tell my why it uses the CPU so much ... and if u have any suggestions about my programming you're welcome
Thx.
Julien.

}your right about the cpu stuff
I did a test on other code samples that use java3d, and guess what, same thing.
What you are worried about, I think is not a problem.
I think you could put thread priorities on it, but that might slow it down.
You could also , rather than have it 100% active on the mouse, make it only move with mouse click??
Maybe you are looking for
