Temps for 1055T overclock

post #1 of 21
Thread Starter 
Hi everyone,

I posted a few times last weekend as I was installing a 212+ in my pc so thanks for all the help guys getting me this far!

At the moment I am running stock 2.8GHz and according to HWMonitor, an idle CPU temp of 30c and core temps of 18c (all 6 cores). I am going to bump it up to 3.7GHz to see what happens. I am hoping the temps wont rise too much (up to the 62c max).

I am aware that the CPU temp can be 7c-10c higher at load so I will bear that in mind.

That seems like reasonable temps.

Ignore idle temps, they are not accurate. You only need to be concerned with what the "Core Temp" is under load.

Your correct that "CPU Temp" is typically 7-10C higher than the actual temp at load (depends on mobo), but the actual temp under load IS "Core Temp". See my guide for more information.

Ok thanks, I have read your guide.

I am running prime95 right now.

BIOS:

Core speed = 3.726GHz

CPU HT Ref = 265
DRAM = 1413MHz
CPU/NB = 2385MHz
HT Link = 2120MHz
vCore = 1.42v
CPU/NB voltage = 1.25v

CPU = 55c (57c now after 20min)
Core (all 6) = 42c (43c now after 20min)

In CPU-Z though, the the 'Core Voltage' = 1.380v but I set this to 1.42v in the BIOS, is this normal?

Also, when people say "keep an eye on temps", do they mean throughout the whole 24hr test or do they stabilize after a shorter while?

** Think I spoke to soon, just came back in the room and the pc was restarting **

**Could it be my NB voltage too low, or the RAM speed needs lowering? **

if your cpu is 95W TDP you got 71'C max temp if the cpu is 125W 62'C ...

Thanks, but the thing that's getting me is I don't know why prime95 fails and why I get BSOD and a restart after 30mins.

Could it be RAM needs lowering, NB voltage needs to go up, vCore needs to go up?

The temps are fine but there are so many variables. Putting them up one at a time is not much good either as I could keep NB voltage at 1.25v and keep putting up vCore until I reach 1.5v when all I needed to do was to raise NB voltage, but how would I know?

I can see by the 1055T spreadsheet that people have all sorts of combinations, 1.375vCore, 1.4v NB etc. I have been told on another thread that 1.45v vCore is a bit overkill (but my test failed at 1.375vCore - after 2mins and at 1.42vCore - after 30mins), so what do I adjust?

The BSOD isn't exactly forthcoming with useful information.

Basically, how would I know that it's the NB voltage that needs upping and not the vCore? I *think* it's these two that I need to get right to achieve my 3.7GHz for 24hrs prime95.

I very much appreciate all the help, will get there in the end

Despite the fact you didn't add any core voltage. The Processor is drawing more voltage to run at 3.5ghz. When you add more core voltage, you're giving it more voltage to play with... like opening the gates up a little bit more.

I set vCore to 1.42v. Is setting it to 1.45v a constant or is that the max that the processor can draw?

I still think 1.45v is too high for me. I can try a few settings in between 1.42v-1.45v.

Looking at this:

Google Spreadsheet

Is there a reason why I keep getting BSOD when I try 1.42v or 1.43v on the vCore, shouldn't that be sufficient for 3.7GHz? Raising to 1.45v, the temps start creeping dangerously close to the limits.
