Vcore and CPU Temp

Hi Guys,
Is it safe to run the CPU Vcore at 1.6V for long term day to day use ? I need this voltage to keep my system stable (i.e. running 2 X Prime 95 for over 24 hrs). On some fourms, I was told it is ok so long as the voltage don't go above 1.65V yet on another fourm, I was told never to exceed 1.58V. Not too sure which one to trust so will just try on this MSI fourm
Has anyone actually measure the CPU temp with an external temperature probe and compare the result with the temp. reading off the mobo (i.e. thru' corecentre, Speedfan etc) ? I'm just wondering how accurate are those temp reported by the MSI mobo ...
My current temp via Speedfan running 2 X P95 (100% load):
CPU: 53C-54C
System Temp: 32C
Room Temp: 24C
NB: 51C
If I switch off my aircon, my CPU temp could shoot up to 57C to 58C at room temp of 28C-29C.
I think the above temp is a bit on the high side (as compared to ASUS board) hence I'm questioning the accuracy of the mobo temp reading...
Here is my rig:
P4 2.4C @ 3.2 GHz
MSI 875P NEO FIS2R
Thermalright SP-94 with 80mm TT SF2 Fan
Corsair 3200LL PRO 512Mb X 2
Ratio 5:4
RAM Timing: 2-3-2-5-8
PNY FX5800
2 X WD 120GB SATA HDD
TDK DVDRW0404N Dual Format Writer
Audigy 2 Sound Card
480W Antec True Power
Thermaltake Xaser III V2000A Alu Casing

Ok, I've taken out the Audigy card, and no, I still need to pump up my Vcore to 1.6V to keep Prime 95 stable.
If Vcore = 1.525V, 2 X P95 fails within the first hour.
If Vcore = 1.5875V, 2 X P95 fails after 13 hrs.
So I guess my mobo is not affected by the Audigy card

But than again ... I need this card to play Need For Speed - Underground
Just wonder if the Audigy card is so power hungry that it draw so much current from the mobo that one need to increase the Vcore and Vdimm to keep things stable...
With the Audigy card, my voltage settings are:
Vcore: 1.6V
Vdimm: 2.7V
VAGP: default voltage
DOT: Disabled
MAT: Turbo
Will see if I could maintain at default Vcore if i remove the card.
Thanks for replying.

I have to keep my VCore at 1.70V with the Audigy installed. My CPU is idle at 32-35 degrees, so I'm not too worried about it dying on me (plus, it's only a cheap 2.4C).
Just to give you an idea, I'm running the following:
2.4C at 3.0 GHz (250 FSB)
MSI 875P-FIS2R (BIOS: 1.8)
1GB Mushkin Level II (5:4, 333MHz @ 2-2-2-6)
SoungBlaster Audigy
DOT: Disabled
MOT: Fast
VCore: 1.70V
VDimm: 1.85V
VAGP: 1.70V
Now, *WITHOUT* the Audigy card, the same system works stable at:
DOT: Disabled
MOT: Ultra-Turbo
VCore: 1.60V (possibly even lower)
VDimm: 1.70V
VAGP: 1.60V
I know it sounds hard to believe, but *Reilly* will definitely back this claim up. Just take the Audigy card out and see what your results are. ALSO, I have read postings in ASUS board forums that PCI slot 3 works much better with the Audigy than any other. Can't confirm that, though.
Post your results!!!!

Vcore and cpu ratio

Hey, i have the K7N2G and i have some problems changing the vcore and cpu ratio in bios...
my cpu is a XP 2100+, it only boots with default vcore and 1.625, and default cpu ratio... if i change the cpu ratio it doesn't boot... what's wrong? what can i do to change de vcore and cpu ratio without crashing? the max fsb that i can use is 157 (~=2050Mhz -> 157*13).

Wonkanoby....I think you are incorrect (but not 100% sure). I have a 2100 Tbred B and I don't have to use the wire trick if I put it in the EPOX...ASUS..... The nforce2 should unlock the Tbred B core, am I mistaken here? I also had the same problem as the above user, but I CAN get the msi to unlock it at some lower multipliers. I'm a little confused why the asus and epox nforce2 boards unlocked my chip, but the msi will not. Any ideas?

Fan speed and CPU temp

Hi There,
I have MBA 13'' Mid 2011.
I'm little bit concerened about Temp of my CPU which is 96°C, and Fan speed is around 6500rpm.
I can hear my fan all the time.
It was not like this always and i'm kind of sure that something is causing this.
I worked before with lots of apps open (itunes, photoshop, text editor, chrom, mail, parallels..) and fan and temp was not this high.
Is there way to find out what is causing this high usage?
Thanks in advanced

First execute a SMC reset:
http://support.apple.com/kb/HT3964
If no change, install istat menus.
http://bjango.com/mac/istatmenus/
Open Activity Monitor to ALL PROCESSES and CPU. Make certain that CPU displays values from high to low.
Post images of both istat menus and Activity Monitor whe the MBA has heated up.
Ciao.

Memory and CPU Temps

Does anyone know if adding more memory would have any effect on CPU temps? It seems that after I added a 512 stick (giving me a tottal of 1gig) my temps have gone up...befor I could over clock this baby to 2.04 with temps in the low 50's even under a work load. Now I cant even clock it without it crashing and temps jumping up to in the 60's with just mild work load. Have removed the Volcano 7 and re-applied greese to it and even tried a stock intell HSF but to no avail. I have not tried to remove the newly installed mem stick to see if in fact that is the problem, wanted to see what your expierances were in this matter. I can say this though and your gonna yell I know...One stick is Samsung and the other is Mitsubishi I belive (at leat the Mitsubishi symbol is on the chips) I cant think that that would make any differance but my knowledge in memory is not that great.
Any input would be cool...my specks are below!
One other word of note, these high temps are with the fan running in low, but even when overclocked I only ran in low, as the high setting on this beast is ever so loud, so if you have any suggestions, by all means list them.
Thanks People!
Paul

Assaf,
Well that did not work, still have high temps, do you think that maybe the cpu it self is going? After all, I was overcloking it for many many months straight. A 1.7 celly running at 2.04 is a pretty significant increase. Think maybe it finaly took it's toll on it??
If so good thing I am looking at a 2.8 P-4
Let me know if thats possable
Thanks,
Paul

P6N Sli Platinum front audio panel and CPU temp voltage issues

Hi All,
I got my P6N Sli Platinum yesterday, build up my computer without any major issues. However I have noticed that my audio front panel does not work. It could not detect my microphone when i plug it into front auido panel, it works fine for the rear auido panel though.
Another issues is I highly doubt the accuracy of CPU temp sensor. Msi 's software monitor reports my CPU temp is around 19-20 degree, I know that's too good to be true even I am using a water cooling system. Btw my cpu is E6600. Anyone else has the similar issues?
The third, I notice my CPU voltage is bouncing between 1.1 to 1.24 in CPU-z. And the multiplier is changing from 6 to 9, frequency is changing from 1.6g to 2.4g. I only see this in CPU-z. Msi 's own software reports CPU running at 2.4g though. Is this cpuz issue or something else?
Finally, any tips to max the overclock potential of this board? I have overclocked to 3.1g but there are some crashes. Going higher the board just won't boot up. I read a review on anandtech.com says 1.22 bios is good for oc. Where can i download that? I only found 1.1 bios on official site.
Any reply will be appreciated.
Cheers

C2D-CPUs have a digital internal sensor to monitor CPU Core temperatures. Have a look at those with Core Temp ( http://www.thecoolest.zerobrains.com/CoreTemp/ ). This Tool reads the temperature data directly from the register of your CPU. There is nothing wrong with the sensor. It is rather the MSI tool that does not read the data it provides correctly.

There is no issue. What CPU-Z allows you to see there is the C1E-feature of your CPU at work. When there is nothing to do your processor will automatically reduce Core Voltages and frequency to save power and keep temperatures down. As soon as the work load increases the multiplier is set back to x9 and core voltages increase dynamically. It is meant to be a good thing.
I have overclocked my system a little and I like that the C1E feature is still working at this speed setting CPU frequency to 2GHz and core voltage to 1.144v when my system is idle.
If you have problems with this feature you can turn it off in BIOS. The option is labeled as "C1E Support" and might be hidden somewhere. You may be able to hit "F4" to unhide it.
The MSI utilities are not the best tools to monitor your system. CPU-Z, Core Temp, Everest, Speedfan, Memset, Rightmark Memory Analyzer for example do a far better job.

3.9 Bios and CPU temp

I have just installed the new 3.9 bios and have noted the cpu temp was sitting on 50c. It is normaly on about 40c when running at 1730mhz. I dropped it back to 1530mhz and its made very little difference. Anyone else noticed this.

AGP Aperture size??? and CPU temp???

1. i have changed the Aperture size to 128Mb (instead of 64) and every time i enter a game, after at least 20 minutes (sometimes less) it kicks me out back to windows.
when i played generals it told me that i might have had a hardware malfunction... which is weird cause i have a new computer.
when i returned the aperture size back to 64, it worked fine, only slower... any ideas...?
2. my CPU reached some interesting tempretures, and i have a lot of airflow... the question is this, when i'm not running any porgram (IDLE time) my cpu sits at around 43 degrees, when i do run stuff (like games, or graphic progs) my CPU rises up to 58, and i even reached 62 once...
is this logical? shouldn't P4 CPU's be cooler then AMD's? how can i force a change on the CPU cooler to work faster (when i change it through Core center the max i get is 4500rpm), can i make it higher?
thanx in advance, EagleIL.

OK,
I have just finished assembling my 865PE monster. I must say, MSI is consistent, the only issue I have seen with them is 2 things:
1. They will never learn to measure CPU temperature correctly.
2. Bios updates never seem to improve things much, or can be a disaster.
Other than that, I checked my temps, and with a side fan and a rear fan and a blower (pci slot turbo blower) out, I had 26-28 deg C at startup (cold iron). My CPU temp was 48 deg C which is physically impossible, and the reported case temp was 38 deg C in the bios but 28 deg c on my independent temp system.
I rearranged everything with side out and reversed one of the rears to blow in, and I have a steady 22-23 deg c after 6 hours. The CPU still reads 48 deg c and climbes to 50-52 under load. The reported case temp is still 38 deg c and climbs 1-2 deg. So I do not believe the temp readings.
I also do not believe all the hogwash about the CPU coolers. The stock Intel cooler has always worked fine for me, and I remember a report that said it was one of the best, in a test against a bunch of them a year or so back. There is good reason for this (I work for Intel, so I know it is not made up): They package the cooler with thier retail chips and also provide them to OEMs. They have to take all the measures possible to ensure the CPU survives the 3 year warranty and the only thing (99%) that will kill a CPU is heat. The heat removal rate of the stock heat sink is sufficient to overcome even the extra heat from OC'ing for the most part, as they test it for that. I believe the rates are posted on the website.
I would say the AGP issue is possibly related to heat effecting the memory on your agp card, or a software issue with the AGP drivers themselves. I would reccomen you revert to another card and try the same scenario if you can. There may be issues using the 128 setting itself.
Good luck. I thought this board would be a nightmare, but it has performed flawlessly with XP Pro, 2.6C, 512 meg ram (CL3!!!)(Elixer), and a Radeon 9000 Pro. I loaded Office XP Pro/Frontpage/Adobe and ran all three with no issues at the same time.

What is the CPU usage of X and cpu temp on your Arch?

I just installed the new arch 2009 02. Everything seems to be perfectly out of box, I have lxde DE.
But I noticed that in idle X is using around 2~3% cpu compared to below 1% in the old Arch I had before. It seems there is a little lag in the desktop experience, not obvious though, but not as responsive as my old Arch. Also the cpu temperature under lm_sensors gives me 43 constantly compared to 39 in my old Arch?! This is not some random sample of temperature, I constantly monitored it to realize it indeed runs hotter.
Also, when I open one mplayer, it uses 40% cpu + 20% for X. If I open 2 mplayer, fan will go noisy and cpu hit full and both videos become choppy! This never happened in my old Arch. I search the forum for quite a while, but have not found exactly the reason.
Some help or information? Greatly appreciate it.:D

Hmm interesting. How old was the "old arch" you are talking about?
Because if it was quite a while ago that you ran Arch and recorded those temperature readings, I might wonder if your hardware is aging or dust is gathering inside your computer case, decreasing air flow and increasing temperature.
My laptop also runs almost constantly around 43 degrees and about the same at X idle. This seems normal to me though.

Pls advise PSU and CPU temp.

At last i have decided to go for Herolchi HEC 525w Dual Fan Ball Bearing ATX Power Supply, after installing the New PSU my CPU Temperature go up by 3 degree...not sure whether all the RAIL will effect the temperature ?
Pls take a look on my comparison : -
Old PSU Young-Year 480W (Taiwan)
Vcore : 1.48 ~ 1.50
+ 3.3v : 3.10 ~ 3.17
+ 5v : 5.08 (no changes)
+ 12v : 11.64 ~ 12.00
System : 35 ~ 38 degree
CPU idle : 40 degree
full load : 57 degree (Prime95 & CPU burn-In)
New HEC 525W (recommded my Intel and AMP)
Vcore : 1.47 ~ 1.50
+ 3.3v : 3.30 ~ 3.36
+ 5v : 4.97 ~ 5.0
+ 12v : 11.76 ~ 11.88 (never hit to 12.00)
System : 36 ~ 39 degree
CPU idle : 43 degree
full load : 60 degree (Prime 95 & CPU burn-in)
Understand that all the variance for the above RAIL are within Spec +_ 5%
Hi All, pls help to post all your RAIL lowest/highest for +3.3v, +5.0v and +12v..as well as system/CPU temperature, thanks....

I would not worry about the extra 3 Deg. C that the CPU is now running at. 60C under full load is well withen normal specs. ..As for the new PSU, I am not familiar with that brand...If you could ,would you POST the AMPS on the RAILS, as that is more important than the Volts...You can find the AMP specs. on the side sticker of the PSU..ie..+12V=?A, +3.3V=?A, +5.0V=?A...THANX..Sean REILLY875

Fan speed and CPU temp viewing Flash video in Firefox vs. Safari ?

My MacBook (two months old) running the latest Safari version (3.1) seems to be working unbelievably hard when viewing a flash video. The temps seem to cycle between the high 60s and mid 70s, and the fan blows at max speed constantly. On the other hand, when viewing the same flash videos using Firefox (2.0.0.12), there is only a slight boost in temp (high 50s to low 60s) and the fan speed hardly increases at all.
Has anyone else noticed this?
Why would the flash player on one browser be so much more efficient than another (Safari seems to labor, while Firebox breezes along)?

Thanks!
Well I guess the code in the Safari browser just wasn't well written. This is true even of the later version of Safari. It does work much better in FireFox, with no crazy heat-up or fan action.
I've pretty much given up on Safari now on everything by my iPhone and iPt, and only because I have no other choice.

Good news for Winchester users and CPU temp. reading after S3 suspend

Bios 3.95 seems to solve all my previous problem with CPU temperature readings after S3 suspend state.
Now the temperatures are after S3 the same as before (15 degree C lower). So Speedfan's control of fans is more precise now. My CPU fan is stopped all the time, in case of warning temperature 50 deg.C, all fans go on 100% (including CPU). With this BIOS I am for the first time fully satisfied with this board.
Cool'n'Quiet is working and S3 as well. I haven't noticed any problem yet.

yo wabrooke, it's amazing u managed to swap out the bios chip from the HP computer set, I got mine same as well. Is that a tedious job? Can give me some guidelines to do it as well? if not, i guess i'm going to change back to dfi soon.
no, very simple. Just turn off your system, unplug the machine, use a paperclip or something similiar, pry the bios chip upwards and pull out (make note of which way the notch is facing), insert the replacement chip, viola! Now you have pretty much the MSI oem board. I think I've heard some boards are red or something (the MSI boxed boards), unless that was an older revision, but other than that, everything else is the same. The only main thing is, if you switch out the bios chips, you can no longer run the disc image to restore the hard drive, which isn't a biggie to me, since I purchased an OEM copy of Windows XP MCE, and I also have and run Windows XP Pro.

Battery Lifetime decreases and CPU Temp. raises with OSX Lion

Recently, I have installed the OSX Lion on my MacBook Pro (bought in November 2009).
Now my device gets really hot and the fan is blowing continuousely.
When I'm checking the activity, I see, that "Dashboard" needs a lot of capacity.
Furthermore, the battery works for less than 5 hours (was 8 hours before).
Is someone having the same problems?

you may want to remove some of your widgets in dashboard as they might not be compatible with lion.

CPU Temp and CPU Fan Speed

I am having a strange problem . One time I will boot the PC and CPU temp is 43 and CPU fan speed is 1308 rpm in Core Center. I do a restart system and the CPU temp is 32 to 36 and CPU fan speed 3308. Not sure if I should trust Core Center . Bios shows CPU temp 48 and fan speed of 3328. I have been reading here that there are a bunch of threads containing some kind of problem with CPU temp or fan speed. My Bios is 1.4. If anbody can give me some ideas that would be great.

Open CoreCenter on deshtop. Click where it says CoreCenter. Click Cool&Quite button. Then Click apply. This drops the fan speed back into the 1400 range and the temp will rise back to the 40s.

How to reduce from 5º to 8ºC CPU Temp on your MSI K7N2 Delta!

I've installed this tweak last week and it is working very stable since then. It decreased my Idle CPU Temp from 42º to 36º and Overload from 54º to 48º:
Just go: http://forums.pcper.com/showindex.php?t=280137

768MB Samsung DDR3200
LG 48x24x48x/16x CDROM/DVD Reader
Dual Fan 450W Troni Power Suppy

It seems that the link to the tweak is broken, I've found another one:
http://ftp://ftp.vector.co.jp/pack/win95/hardware/other/wpcre14.exe
This is what the article say:
Just tried it for the first time..It works GREAT
My idle temps are now 26c, down from 34c. That's 8C. I can have Winamp, IE and messenger running and CPU temps don't get by 29c. Once i fire up, SETI though...I get back my regular Load temps at 39c.
Some of you probably know about it, already....here's for thousand others that don't.
This tweak can drop your idle CPU temps down as much as 8c, maybe more...depending on your system.
First thing you need to do is download WPCRSET & WPCREDIT.
They're both in this zip.
- Extract to a directory.
- Run "INSTDD.EXE". Click Install. When done, you will be prompted for restart. Hit Yes! -
- Then go back to the folder with extracted files, and open "WPCREDIT.EXE"
- A ms-dos like window will pop-up. Move the blinking block (with arrow keys or your mouse pointer) until it says Offset 6F at the buttom. Now, click on the two digit number where it says "HEX", and change it to 1F (The Hex for Offset 6F would have previously been 9F, 8F or something else). Hit Set.
Your idle temps should now start falling.
You would have to do this hack/tweak everytime you rebooted your computer if it wasn't for WPCRSET.
- Go to directory and run "WPCRSET.EXE"
- Look at the top of the window: Enable select "Start" and make sure Device is on "enable"
- Then click Add. Enter 6F for the register, and 1F for the data
- Click Ok and you'll be prompted to restart.
Once, you rebooted, open WCREDIT again and see if the 6F register is still on 1F. If it is, then that's it..You're all done.
Here's a Screenie of how it should be:
This only brings your idle temps down, and not your full load temps
It should work for all nforce2s, and use at your own risk
Check your nf7-s for CPU Disconnect. Most other nforce2 motherboards do not have this feature in the bios...so this tweak might prove useful.
READ THE WHOLE THREAD BEFORE TRYING THIS!
If you run a Distributed Computing project...then obviously this would be of no use to you

It activates the C1 (and maybe the C2) function Athlon XP CPU's support. Most mainboard brands have this feature as an option in the bios you can enable and disable. I just found out that EPoX doesn't have that feature. So what you're doing is just using a direct reg tweak to activate it. It's not like you're forcing anything, the Athlon XP chips are made to support this feature so it shouldn't do any damage.
When the CPU is idle the mainboard will send a command to the CPU that will cause a part of the CPU to be deactivated (and therefore not produce any heat). That's why this tweak only works on the idle temp and doesn't change anything on the load temp. Ofcourse as soon as the CPU power is needed the deactivated part will become active again, so it should have any influence on the performance of the CPU.
Strangely, my full load temp has decreased 6º C degrees too.

Macbook pro 13' 2012 fan problem? (high cpu temp)

my macbook gets cpu temp at 98C and then the fan starts raising speed from the default rpm(2000rpm).
with heavy cpu usage and cpu temp at 93-100C, tha fan waits about 2-5 minutes and then kicks in and increase the rpm( the higher rpm i saw was 4000rpm at 101C cpu temp). all the other time the fan speed is between 1995-2004rpm.
Is this normal?
I've already tried SMC and PRAM reset and clean OSX installation.

thank you for your answer.
But is it normal for the fan to wait so long 2-5 minutes and then start raising the rpm?
I expected that the rpm will go up simultaneously with the Cpu temp. Like if the Cpu starts increasing temp (about 70-80C) the fan will kick in...
I know from a friend with a Macbook retina that his fans keep spinning at 3000-4000rpm and always keep the Cpu temp close to 60C. I know that the architecture is diferent but the cooling logic should remain the same. right?
