Different cpu temps after warm boot

After cold boot my CPU temp is:
Load: 46ºC
Idle: 39ºC (cool & quiet enabled)
After warm boot temp drops to:
load: 42ºC
idle: 35ºC (cool & quiet endabled)
I'm using bios 1.5b2.

That however is not correct for everyone. MSI is aware of the problem and will be working on it in a future version of the Bios.

  • 2 identical machines - different CPU temps

    I recently built two XP3200+ identical machines (specs below). All parts were purchased from the same company (NewEgg) and both processors were retail packaged. My concern is the CPU temperature on System 2. Here are the vitals at idle with about 1 hour warmup:
    System 1
    CPU temp: 43 C
    CPU Fan Speed: averages 3800 RPM
    System temp: 38 C
    System 2
    CPU temp: 55 C
    CPU Fan Speed: averages 4300 RPM
    System temp: 38 C
    I know both CPU temps are with allowable limits but why would they be so different?
    BTW... I did try removing the heatsink, cleaning it and the CPU, then reapplying Arctic Silver 5 and got no difference in temperature readings. Anyone have any ideas?

    I have a problem with this corecenter too. I buy a thermaltake cpu fan and my cpu tem. dropped about  40C . After that i think i updated corecenter.And i didn't looked so much to corecenter.One day i saw that in corecenter my cpu tem is about 50C. And that night i updated corecenter again and my cpu temp. dropped 42C from 52C  
    Which one i will trust 52C or 42C. I am frightening to hear don't trust both of them  

  • High CPU temps after kernel panic.

    Recently I've seen my Mac Pro 8-core CPU temps rise pretty considerably, between 10°-15°C after a bone head move on my part.
    After setting up a new Vista x64 virtual machine in VMWare Fusion 2, I was trying to get a Linksys USB to Ethernet adapter (USB200M) to work inside this virtual machine, but with little success. After tracking down a driver online which I thought at the time was a match for the chip on the adapter, I tried to load the driver manually in the virtual machine. This unfortunately resulted in an immediate OS X kernel panic; my first and only on this machine.
    Since then, my CPU temps have been on the rise. Not sure if its even possible for a kernel panic to damage hardware, but I’m wondering if any low-level software damage resulting from the kernel panic could be causing the higher temps?
    I tried a simple restart which did nothing. I have since run the extended Apple Diagnostics and everything appeared OK. Also, ran a “fsck” check and everything appeared OK there as well.
    Any feedback, suggestions or advice?
    P.S. This is an Early ’08 2.8GHz 8-core Mac Pro with 10GB third-party RAM. RAM has been thoroughly tested and running in the machine for over a year now without incident.
    Thanks

    No, ethernet ports work fine.
    I use the adapter to connect a VMWare Virtual Machine directly to a VPN Netgear router which runs a remote VoIP service, available on Windows only. To make a long story short, I ran into all kinds of performance issues when connecting the Mac via Ethernet directly to this crappy little Netgear VPN router.
    So, the alternative was to use the USB to Ethernet adapter to connect only the VM directly to this router. Definitely not ideal, but worked fine with XP.
    It was when I upgraded the VM to Vista x64 and tried to install the driver for the adapter that I got the kernel panic and now higher CPU temps.
    Still just curious if I could have damaged any hardware?

  • MOVED: MSI P45 Platinum won't post after warm boot

    This topic has been moved to Overclockers & Modding Corner.
    https://forum-en.msi.com/index.php?topic=125291.0

    Thanks for the reply DougKmcse
    I have no trouble with the overclocking since this is only a minor overclock (2.8GHz), the only problem I have with this is it gets stuck at restart. With that 2.8GHz OC, i have the vcore @ 1.285v which was stable running 1hr Prime95. I just can't understand why it gets stuck during warm boot.. might try to experiment (400x6 = 2.4GHz) when I get home from work to see if the 400 FSB is causing this. And yes, I agree with you that it would be easier to use a lower FSB with a higher multiplier. I just wanted to try having 400 and having a perfect 1:1 ratio. I have some data suggesting a 1:1 (@ 400:400) is better than 1:1.2 or any other divider. I used Everest cache & memory bandwidth benchmark to test this. I got lower "ns" testing my RAMs (PC6400 DDR2 800) during 1:1 FSB:Ratio (400:400) vs 1:1.2 (333:400)

  • Quad G5 Vastly different cpu temps

    I've been overworking my machine to the point where it randomly puts itself in sleep mode. I realize now that it's probably overheating but when checking the temps I'm getting readings that are very different between cpuA and cpuB, like 80-90 degrees different. Is something wrong? Is there a coolant problem perhaps? Shouldn't they be nearly the same?

    I just had it put itself to sleep. This is a few seconds before and after the sleep. Does anything here raise a red flag?

  • Mid-2009 macbook pro high cpu temp ( 100C) after every cold boot

    Hi everyone,
    Every time I cold-boot my MBP, the CPU temperature sky rockets to 100C within 3 minutes at idle with the fans barely kicking in until that point. The activity monitor shows 97% idle with no major processes running and this issue is reproducible every time I turn on the computer. However, if I immediately reboot the computer (warm boot), the computer runs normally (~70C CPU temp, fans @ 2000 rpm). If I do a SMC reset, the computer boots normally for the next immediate single cold boot but symptoms return thereafter. The only way to prevent the high CPU temperatures is to do a SMC reset before ever cold boot.
    I'm wondering if someone else has had these symptoms with their laptop and how they fixed it. The system is still under apple care and the symptoms are reproducible but I'd rather not bring it in as this is my daily-use machine.

  • Two CPUs run at different temps after service?

    I just got my dual 2.3GHz G5 back form the Apple Store -- I brought it in because one of the memory simms seemed to have gone bad. When I got it back they had replaced the memory. And the logic board. And one of the CPUs. Hmmm. Nothing but the simm was showing errors when I took it in.
    Anyway, the first thing I noticed when I turned it on was that unlike before, the fans run audibly all the time now, even if I have an external fan blowing on the case. So I ran Temperature Monitor and saw that one CPU was consistently running 15-20degF above the other -- I've never seen a split of more than 5-7 degF in this machine before. Also, previously at idle and with a fan blowing on the machine, the processors would drop to about 99degF, but now only one of them will, the other stays in the 115-120degF range. So it seems like one of the processors is running hot now. (Strangely Hardware Monitor shows the CPU fans as running at the same speed even though the CPU temps are that different.)
    Has anyone seen this before, if so do you have any idea why and/or did it lead to any problems, and did Apple resolve it for you? I'll probably go back to the Apple Store tomorrow anyway because they forgot to reset the serial number on the new logic board. But I haven't been able to find much on processors suddenly running at very different temperatures, so I'm wondering what to expect.
    Thanks.
    iBook G4, Dual 2.3GHz G5   Mac OS X (10.4.5)  

    I'll mark this as closed now, and explain why the Apple Geniuses (or at least one of them along with his store manager) are gods.
    After taking another look at my poor machine the attending Genius called me and told me his store manager had agreed to just replace it with the equivalent current model (one of the dual core ones instead of my one generation older dual CPU one). Maybe this was because they spent a week replacing parts and it still wasn't a happy machine and they didn't ever want to see it again. Maybe it was because I was really laid back and nice about how long it was taking (to be honest it couldn't have picked a better time to die, I don't have time to use it right now, so I wasn't very upset about losing it for a few weeks). I don't know. But the thing that made me really happy was when I asked if I could upgrade to a quad for the difference in price, they said yes. Who would think your computer dying could make you happy? Many, many thanks to the folks at the Apple Store.

  • Correct CPU Temp?

    Hello everyone.
    how can i know if the cpu/nb/system temperature being shown from the bios and core center is accurate?
    previously, my cpu reading @ idle says 44 degrees and reaches 65 degrees @ load. that was when my bios is v1.2 on my k8n neo - fsr.
    i flashed my bios to v1.4, the reading is now 34@ idle and 45 @ load.
    please help.

    The problem was reported to MSI and the answer was that the bios does not read the winbond chip correctly on initial startup as it is only active after posting....
    ....Here is the way I understand it to work. For whatever little it is worth anyways.
    Cold start
    System board reads Bios info, if you enter bios at this stage; The Winbond chip has not yet been given the multiplier for the Core you have.
    Continue to boot and the multiplier is passed to the Winbond chip along with VCore info and that is then transfered to the CoreCell chip to digest for Cool & Quiet to work, setting fans and adjusting multipliers for the chip as well as VCore for a given circumstance.
    Unlike older systems that had the Temp sensor under the chip we have a built in Temp sensor in the CPU. These vary based on what core you are uses as read by the Bios. So until you boot up the first time the Winbond takes it's best guess based on I think the Clawhammers specs, which was the first core anyways for the A64's on the 754 boards.
    As the Newcastles use a different Diode as a sensor those first readings will be off. If you have a Clawhemmer they settle.
    MSI is not really at fault for designing the systems to work this way as AMD never told them they would be changing the diodes in the cores. So I am not sure it can be fixed. However if you do a reset after a cold boot post the readings should be OK I think from that point on.
    In short, this problem is not going away, and a BIOS fix won't solve it.  Tiresmoke is referring to the Neo1, but it's the same basic issue with Neo2.  Also, Syar2003 posted a bit of interesting information on the temperature problems in the following thread:
    neo2 plat and amd 64 temps post here
    Not sure what's fact and what's fiction, but in the end, we just have to live with it I'm afraid.  Good luck!
    If the above explanation is *true* (and I very much doubt it), then this can only be described as a BUG.
    There is no intrinsic reason why all the necessary initialisations and passing of data cannot be performed at cold boot as well as warm boot.   To use this as an explanation - or an excuse - is pure hogwash.
    If the bios has been programmed this way, then its plain stupid and needs to be fixed asap.

    EDIT:  Tiresmoke:  The issue affects Winchesters too.

  • Up to date K7N2 Delta2 CPU temp query

    Hi all, just installed my first MSI board, K7N2 Delta 2 with a Sempron 3000+ chip that I previously had installed in an Asrock K7VT4A pro.  Anyway, it's the old "oh heck the CPU temp has gone up to....." one.  Idle on the Asrock was around 42 - 45 c, on the K7N2 its 50c.  After initial panic (after all, op range is quoted as 0 - 95c for the processor) I removed and reinstalled the cooler with a new thermal pad for no change in reported temp, and flashed the bios to 11.5/B5  - again for no change in reported temp.
    The ASROCK doesn't have that little tongue thing sticking-up under the socket (sorry if I'm getting too technical for some of you here) so I'm guessing that it is taking its reading from the socket, in which case the higher reading on the K7N2 is to be expected, but I'm a little confused between all the temp reporting revisions mentioned in the forum for the different bios levels.  Is 50c with BIOS 11.4 and 11.5 OK or has the reading been revised down in these levels, in which case it's high, or has it been revised down and then up again, in which case it's OK 
    I'm running Sempron 3000+, no OC, 1G Crucial in 2x 512 sticks, Akasa AK-827RD rated for XP 3400+, akasa thermal pad, in a Coolermaster Centurion 530 with 2 x 120 mm case fans. CPU fan is running at 2445 reported by Core Center in manual mode. PSU is AKASA Powermax 460. Case is tidy with cables fastened back for good airflow.
    TA much
    Andi

    Hey folks, thanks for the responses.
    CPU is correctly installed, I even had a moment of anxiety about this yesterday and reinstalled it to check.
    Fans are maxed, I set Core Centre to manual and maxed the CPU and NB fans.  The Smart fan settings in bios are disabled.
    Tower is under desk, desk is actually a table so no solid sides nor back to restrict airflow.  The Centurion is a good cool case, taking the side off makes virtually no difference and system temp is showing as a decent and consistent 25 - 27 c (room is 21c).
    Everything except the mobo is the same as it was with the Asrock, even the position under the table.  I even checked in case I had rammed any of the fan connectors on the wrong way and was blowing in reverse (that sucks!).  For the record, the front system fan is sucking air in, the rear system fan is blowing out, the PSU is blowing air out of the back of the case, the CPU and NB fans are blowing air onto the board, and the CPU fan has a duct to a vent in the side panel to help it bring in cool external air.
    I just ran the machine for a couple of hours at 98 - 100 % CPU by running a bunch of audio tracks in Cubase with plugins on every track and the temp has remained steady at an indicated 58 - 59c. My idle CPU rate is around 2% (these figures from Task Manager).
    I'm still intrigued by the 41c indicated at boot after overnight cooldown, has anyone done this or would anyone care to do it and share the bios temp reading, I literally hit the power switch then del, straight into bios and then directly to the hw / health tab.
    Incidentally, I thought that all Sempron 3000+ CPUs were Bartons (I know the MSI list says Thoroughbred but I thought they were all 512kb L2 Cache chips - anyways, mine is apparently a Power PC 604, x86 family 6, model 10, stepping 0, so I figure Barton?).  Barton op temp is quoted as being 0 - 95c by AMD, and confusingly elsewhere AMD quotes max temp as 90c - in either case I have a bit of spare range.  I'm running it with an ext clock of 166, auto multiplier and it's giving me 2166mhz.
    Again, thanks to all; I know that this is pretty well a "done to death" subject and I really do appreciate the help.

  • Do the BIOS that fix CPU temps simply lie about it?

    I have a Newcastle A64 3400 with the K8N Neo Platinum (W7030).
    Whenever I turn on my PC from a period of inactivity the temp says 55-60C, when I then reset the PC it says the temperature is in the 30s.
    The only place I could get my case temperature probe is wedged between the fins of my CPU heatsink and that always reads about 40C or up to 45C under load.
    Can this be right? Which of these temperatures should I trust and would my heatsink generally be hotter than the temperature of the actual CPU?
    I'm getting these readings from Corecenter btw, it also says the CPU fan is spinning at over 5000 rpm under load, usually around 4000 rpm idle.
    Cheers for any help!

    There is a known cold boot temp issue. It gives false readings after a cold boot but the temps are supposed to be somewhat OK after any warm boot. As temps really don't affect you and it would take some pretty high temps around 70c to bother anything my advice is to ignore it.

  • Please Help New Mobo CPU Temp 255 Deg Celcius

    Hi, I just bought Big Bang Marshall with all the new computer part yesterday, after i finish installing everything then i started the computer, went to BIOS was planning to choose my boot driver, then i went to check the cpu temp. the cpu is 255 degress at 4.6mhz speed which i have not configure anything yet not even overclock yet. but then i put my hand and feel the temp in the cpu cooler it was warm not hot at all. but i worried that the 255 deg is real and might blow everythign so i turn off. thats the only time i turn it on, then today i phone the shop and the shop didnt know anything they never experience 255 deg. so i need to wait till monday until msi customer service open. but i got whole day today, i am wondering if people can help so i might able to fix the issue. should i continue and install the windows or should i wait till msi open again? thank alot
    my part is:
    mobo: Big Bang Marshall (B3 rev)

    As long as the RAM defaults properly to 1333 like it is supposed to, all should be fine with having 2133's installed. RAM speed is kind of a sore subject with the Sandy Bridge platform. Not much is gained by 2133 in performance, but if you wish to persue more speed, please open a thread in the OC, Undervolt, & Mod Section of the forum.
    thankss alott

    If you are not into extreme overclocking, then indeed a JEDEC standard 1333 set is all thats needed.  If yours defaults to 1333 though and is stable, then you should be fine. 
    thankss alott

  • CPU heat & win XP boot/load problem

    I have been experencing 2 big problems with my new set setup.
    First one is high temp are being reported for the CPU.  I have stock heatsink installed on the CPU. According to speedfan, idle temps around 40 - 45 C and on load temp goes all the up over 60, around 61-63. MSI core cell (ran it seprately) reports about the same, but the high it had was 65-66C. I had arctic cooling HSF installed but took out since it was giving me high temp around 70C on load, so I took it out. Possibly I couldn't apply the thermal paste (the one that it came with) properly, tried 4 times and seems like the arctic Heatsink isn't working right anymore. did run a Prime95 test for 8 hours and it finished with 0 errors/warning. The system seems stable after it loads up.
    Second problem is booting up win xp. Frequently window XP goes go the loading window XP screen and after that it crashes. After a couple crashes it does boot into win XP though. Like mentioned, after win XP is loaded it is stable. Also I have noticed if I restart windows XP after sucessful boot, it reboot without crashing. However, if I even turn of the comp for 5-10 mins and boot up, window XP crashes when it trying load again.
    Here are specs that i have right now:
    Athlon 64 3400 socket 754 newcastle
    MSI Neo Platinum with 1.4 verions BIOS
    corsair 512 MB ram
    120 GB ATA seagate HD (main)
    40 GB ATA WD HD (secondary)
    Thermaltake 480w PSU
    Any help would be appericiated!

    Corsair is value ram wiht 2.5 CAS, also don't think that got any problem at all. Like said windows is stable after it loads. Also I think I found the problem with booting, I removed a 2nd old HD that I had in there. Now it is booting properly.
    Now about that temp, I decided to check it out myself. I let prime95 run for 40 mins and let go max temp. This time speedfan showed only max of 58C, while core center showed 62C. I touched the bottom of the heatsink and it was midly warm to hot. I also checked with the temperature sensor that is on my thermaltake case. The LCD on case showed only 40-42C. So could the core temp actaully be 20C warmer? Also another thing I keep on seening people with "K8N Neo Platinum bios 1.5B5", is that a better version of the bios and does help with themp reading??

  • Huge CPU temp fluctuation - high temp

    I have K8N neo platinum (socket 754)  with latest bios with cool n' quiet on. I am currently using the stock Heatsink and fan. My temp reading for CPU changes drastically from idle to full load. According to speed fan (and core center) the temp idles out at 38 C but at high load it goes all the up to 66 C. I was think the temp change so big, I usually hear that idle and load temp are bewteen 5 C of each other. I tried touching the Heatsink after running it and load and it felt hot, but it didn't burn my finger.  Not sure if heatsink isn't cooling right or is it a temp reading error. The current BIOS supposedly gives accurate temp reading, so just might be problem with the heatsink. Any idea whats going on?

    I guess you haven't read any posts here at all. Yes virginia there is a problem. False readings using the Newcastle and Higher core after a cold boot. The false readings go away after a warm boot.
    You are also wrong about the 5C difference from idle to full load conditions. While it varies it can be as much as 25c difference if you are using Cool and Quiet. 15c is more in line for those folks not using C&Q.
