Yup, even I don't trust one app when it's regarding to measure temps. I use everest ultimate, core temp an real temp ( running always in background ).

But in techie_85's situation as the bios and cpuid temp monitoring app is showing the same temps I think that the app is right.

For damngoodman999,
Processor AMD Phenom II X4 940BE at 3GHz stock cooling. Motherboard: GA-MA790GP-UD4H. BIOS - F2. All other BIOSes gave me temps higher by 6-10 degrees and hence for me, F2 works.

This one is at stock 1.34V vcore. Also I started the HWmonitor app a little late, so the min temp is 61 degrees. Load temp measured by running in place large FFT's for about 3 hours minimum.

Since the core temps are reaching 73 degrees max on 100% load, I decided to lower the vcore to 1.25V. Ran Prime95 for 3.5 hours and see the results. Max temp 65 degrees. Which I think is AMD's company specified limit for these processors.

Further undervolting lead me to 1.216V, where temps are 64 max, but usually 62 degrees on full load. Under volting any further lead to BSOD after 15 minutes of prime95.

Now, I am clocking my CPU higher through the multiplier. The stock multiplier is x15 and frequency = 200MHz. SO, 200x15=3000MHz=3GHz stock.

I clocked to x16 and got BSOD on boot at 1.22V, so I have clocked to x15.5. Will stress test and update by tonight.

Super quick UPDATE: Black screen on running stress test at 1.22V, multiplier x15.5 = 3114MHz. Now back up to 1.25V and 3114 MHz. Stress testing.

What should temps be ideally for our processor under full load? We both live in especially hot/humid places and hence we get similar temps.

i think these temps are not correct !! :-|

may be sensor defect , AMD Phenom X4 9550 which i used before buying P2 940 , its 65nm procesor with stock cooler that cooler is normal AMD stock without heat pipes

P X4 9550

temps are
Idle 39
Load 56

But P2 940 is not meant to hiked this much temps - as gigabyte support told me that all 45nm AMD proccy's sensors are correctly detected & they told not to update bios for P2 940 on MA790gp-Ud4H motherboard , they told that if system temps are higher than the core temps then core temps will be always higher than the system temps so they told not to look @ the core temps they told to use the infrared sensor to calculate

Techlo!!!!

Just leave it unless it gets restarted or Any BSOD

^HEY! I am Krow! ;) :lol:

Anyway, coming back to the point. I am uncomfortable with seeing my temp touch 80 degrees, sensor fault or not. Did you use infra red sensor to calculate? Any difference?

Right now, on 3116MHz @ 1.26V and running stable for prime95 10 hours. Max load temps 69, but usually its 67 degrees. Hot I know, but certainly lesser than the stock 79 degrees. I'm going to be OCing on stock via the multiplier only till I touch a max load of 79 as it is safe. Then I will buy a cooler (OCZ Vendetta 2 looks to be the one now as TRUE nonbalck is out of stock and I can't lap/mod any cooler).

OCZ vendetta 2 is good cooler , but see whether any difference is there ??

but buy the best thermal paste like ARCTIC SILVER 5 or MX-2

^Well, lets see. One guy from Kolkata used Vendetta 2 on Phenom II X3 720 on some ASUS mobo and he got load temps of 40 degrees. I think the sensor must be faulty in the gigabyte mobo.

ya thats right sensors ! but running without any errors - wen u r going to buy new cooler

I want to buy today, but I am holding my self back. Let me check what OC I can reach, then I will buy a cooler to see the difference. I am still confused about the cooler. SBCCF is a NO as it installs well for some and not for others. Vendetta 2 looks nice, but TRUE Black also looks cool. The problem is that TRUE needs to be lapped/modded for best performance and Vendetta 2 is nicely within my budget. :)

As far as i have concerned Vendetta 2 is good & also Hyper 212

SCCF is total waste dont go for that - get better fan for Vendetta 2 !!

No Hyper 212 for me, it is good no doubt, but Vendetta 2 is surely better. I think that is the one I will settle for. Now let me get a stable highest OC and I'll get it. Now @ 3.2GHz @ 1.296V. What is your vcore for 3.5GHz?

1.35vcore u can OC to 3.4ghz , use lesser vcore & more OCing

ask asigh / topgear :grin:

Hmmm... topgear, will reply when he is here tomorrow morning, as usual meditating on TDF. Well I am on 3.2GHz at 1.3 so I suppose 1.32 should take me to 3.4. What's your vcore and temps?

There's no particular rule for vcore and OC. They all depends on trial and error method.
You can reach 3.4Ghz with 1.32 or you may reach that speed with a little less or more of that vcore and do keep in mind that it's not a good idea to get the an idea about stable OC with stck cooler. Simply stock HSF is not sufficient for OC in hot climates. So
you should 1st buy a good cooler and then you dicover of real OC will begin :p

Before using hyper I was only having stable OC of 2.7Ghz with my e5200 but with hyper i can go as high as 3.6-3.8Ghz :p but currently running at 3.33ghz as I don't need to run that proc @ 3.8Ghz always and 3.33Ghz is sufficient for ( though as of now maybe :p )

As for cooler vendetta 2 is better than hyper 212 but the best bet would be TRUE 120 though the only catch is you need to buy a separate fan for that.

But, does an unmodded/unlapped TRUE give better performance than the Vendetta 2? The thing is not only about the fan, TRUE (non black) is outta stock and I would have to get the black which is for 3.5k. I don't think it is worth the premium especially when people have achieved a stable OC of 4GHz even on the SBCCF in India (one is in TE). I think Vendetta 2 should do the job, but the temps are bothering me really. On stock, 70 degrees on full load is a bit too much, isn't it?

Dont belive in TE guyz sometimes , i ask one of them to post their OC & temps - then he escaped .:grin::???:

see its ur first CPU cooler so u must buy as for ur like - anything u like then u ll know about how cooling
