What are normal temps for an overclocked Opteron 165?

[aggressor]

I have 2 120mm Panaflo fans handling case airflow, and a XP90 with a 92mm Panaflo handling cpu cooling. Under dual prime95ing at stock speeds (9x200=1.8ghz), it reaches about 47-50c. When I try 9x280@1.44v=2520mhz, the load temps can reach as high as 63c!

I've read many comments about how cool the Opterons run with stock cooling, and that an XP90 with a decent fan is about the same, so why are my temps so off? I don't think the temp sensors are wrong as Prime95 will fail after an hour or two running at such a high temp. At first I thought I applied the thermal paste wrong, so I reapplied it but that didn't seem to do anything.

Pretty normal. I know some people exagerate how low their temps are. When I had my 4200+(the month it came out), it was reaching 65 degrees at 2.7, with 1.5 volts. 1.43 volts and 2.6GHZ got it to 56 degrees. At that time, people were claiming temps as low as 50 degrees on full load with an xp-90.

My advice for you is to keep the cpu at around 2.4GHZ, with voltage at 1.4.

i believe dual cores generate more heat than the single core ones..thats probably why..the opteron 14x series ocs a bit better

 

[imported_Seer]

Well, what is your ambient temperature? If you are in the southern hemisphere, it's the end of summer right now, so it might be pretty freaking hot.

 

[shootsfor3]

63 under load!?!?

I have an opty 165 @ 2.52 that i've been stress priming for 4 hrs now as i type.

Well i'm typing on my laptop.
Temps are 41-42 under load, 30-31 idle. Something is off on yours.
I'm using as5 w/stock hsf.
The vcore is 1.375 in bios and under 100% load is 1.41 in windows.

 

[black318is]

Something really is wrong with those temps...Mine never goes over 45 under full load and that is with the voltage up'd (6 hours dual Prime95). It sounds like maybe the HS isn't mounted properly. At stock speeds (not overclocked) mine would run below 30 idle and around 35-36 under load. Are you also sure all your fans are running at max?
Can you give some more specs on your setup---Board, case, etc....

 

[Cook1]

Yeah, that seems a lil toasty to me too.

What motherboard are you using?

That's insanity! I have an unlidded Opty 165 that, at stock speeds no less, primes at 60C. I am using AS5 on the core and have reseated the HSF once. Temps only dropped 1C from the reseat so I doubt it was sitting terribly askew. I have also opened up the case to see if airflow was my problem but that only dropped temps by 3C. That being said, I have touched the heatsink at load and it doesn't feel very warm at all. How the hell are your temps so low at overclocked speeds and mine so high at stock speeds? What kind of cooling are you using?

 

[CP5670]

Some of those temperatures seem very high. I never get anything above 42C with 1.425V at 2.85ghz (it's on a big typhoon, but still very low). Maybe the temperatures vary a lot with the different steppings/batches.

 

[allies]

It all depends on ambient temp.

We're talking a difference of 18C between our two temperatures. I'd say my room temp is around 26 or 27 C typically. Are you saying that all these people with low 40's load temps are sitting in rooms at 10C ambient and less?? I know all about heat transfer and that differential is what governs it but I think that is a stretch.

 

[MrX8503]

those temps seem pretty high.

My opty 165 is at 2.6ghz 1.375v 12+hrs dual prime stable and idles at 30c and reaches as low as 27c on cool days. Hot days such as 80F my idle temp is 33C. But when my comp was priming for 12 hours it reached 45C max.

I'm using an ac freezer pro 64 with 100% fanspeed.

 

[nealh]

first off this is key..it is almost impossible to compare temps

ambients play a big role....my ambient in FL ranges from 76-78F(sometimes closer to 80F)

second most mobos are read temps wrong...DFI Expert is known to be 10C too low!!!!

For me:
0pty 170@2800 1.43v bios set..underload..DMM DFI overvolts to 1.45v
ambinets that ranged from 24-26C idle at 32/33C..load 10hrs Dual Prime 95 large fft 42/43c

I have an offset temp of -4C..when means my real temps are 4C too low

this is under water

 

[alpha88]

thermal paste?
room temp?

 

[soloz2]

that is pretty high for a dual core. you don't want it to get above 50-55... and most dual cores react aversly to temps over 45 when OC'ing. both my 165's never got over 38 (custom water)

what stepping do you have? the CCB1E's tend to run warm

 

[SparkyJJO]

touch your heatsink. It it hot? I had a mobo that the temp sensor was all screwy or something because it would read 65*C all the time, even if I just booted the system. That might be the issue is just the temp sensor.

Hey i have the same problem! Im using the 4-heatpipe stock heatsink, which is the equivilent of an XP-90 give or take a degree. Ive concluded that my fan is garbage, or its not running at full speed for some reason. My old socket 754 rig used to ramp up the fan speed when priming and keep the temps stable, this rig simply dosent, either speedfans not playing nice or the fan simply dosent have a high RPM. Im absolutely convinced its my fan, so i think you should check yours.

 

[aboothman]

1: Temps sensor on your board may be off

2: XP-90 is a great heatsink, but I have noticed that it is less efficient at higher temps.

 

[TrevorRC]

Delta is more important than temp sensors.
A 15C difference is relatively common with air.

[P0pinjay]

Ok, so I slapped a TT big typhoon on my opty and stock load temps actually went up to 66C. Obviously I must've done a poor job at it. Even so, I just didn't buy it so I did a little investigating. I felt the heatpipe and HS coming from my chipset and it was HOT. If I had to guess, it was upwards of 45C. I felt my RAM heatspreaders as well. Again, just a guess, but I'd say they're around 40C. Then I felt the CPU heatsink block...It wasn't even warm. It's made of copper so it should be conducting heat better than my all steal chipset heatsink/heatpipe. But, from the base to the aluminum fins, there is barely a temperature change, much less anywhere that feels remotely close to 66C. I have access to independent thermocouple readers at my job and I'll try to get some more scientific data next week. For now, though, I think the only conclusion I can draw is that the temp sensor is horribly innaccurate. I'm going to proceed with my overclocking efforts in the mean time. I'll just have to let prime errors be the warning that things are too hot....
