temp isn't realllly an issue as long as you're not doing this in the middle of the afternoon.. haha..


Stock cooler is good all the way to 4.8ghz if ur chip can do that on < 1.45

It will crash @ bench.. but if it's stable.. the cooler can handle it, because you'll never run into real life situations that is the equivalent of small-ftt on Prime95:rolleyes:


also.. Intel burn test does not heat up this cpu due to missing avx extension.. so... I keep having to repeat this to people.

on a 4770/90 k no..

but on THIS particular chip.. 4.4 vs 4.9 is still like 5-15% difference in some games...

Wow that's impressive!

I'm sure that 500MHz is doing something, as tp4tissue said in response.

I'm not sure of what performance boosts its granting though.

Yeah, I know about the missing AVX. Normally I use x264, but I didn't have it installed yet.

most likely making up for the lower cache:rolleyes:

except small-ffts don't generate more heat than large fft sizes thumb.gif

8k and 16k are within 2C of 1344k, at least on my pentium.

Running 4.73 @ 1.425v, under a LinPack stress (Intel Burn Test), I only hit 86 max. Provided, I'm in the norther US, so that may contribute, but still.Maybe your airflow isn't very good in the SG05?

Edit: To anyone looking at voltages, they were pretty rough, and not exactly fine-tuned. I was just running to see how far I could get my chip.

Thanks for the reply. This prompted me to do some quick tests to see how much of a factor airflow was, particularly as I had my PC in a cupboard under the TV (it does have some holes and I leave doors open when doing anything stressful!).

I used a 5min stress test with Intel XTU to keep things quick. Previous tests had suggested 5mins of this gets close to what I get overnight on x264. Doesn't show more than about 2oC difference between in cupboard and open air with case removed. I also tried switching the PSU orientation which suggested it might be marginally better, only 1oC or so, with intake from above rather than from case.

Think I will get an aftermarket cooler, I guess should be a good investment as I can reuse if I upgrade my cpu later.

A few pics below which are hopefully readable after resizing.

Cheers

thats is true 4.4 ghz is enough for gaming. Since i got a water cooling, just want to push its limit. I did try go to 5.0 ghz, end up with blue screen.

i keep drooling over it since it my limit.drool.gif
At first 4.8 ghz was my limit so yesterday i try increase because i remember i saw this youtube video http://www.youtube.com/watch?v=6eLMs1vB_tI

Ehhh. I dont understand this CPU. Can someone help me? I can pass Prime95 with blend test (6GB ram) and small FFT ans large FFT. I ran 6h for each i was happy for "stable" OC but when i try x264 stabilitytest i just get these ******* bluescreens :/ always with 0x9C but why, i ask WHY!! increasing vCore & vCache BY 0.01 didnt help and VTT too so ***?
