XS INTEL CORE i7 STABLE OVERCLOCKING DATABASE

I was just thinking that I have seen or experienced 8 hours of stability testing, but cant run 24/7 for an extended period of time.

If a system can run for at least a month straight 24/7 then I would consider it stable. I havent run stability tests in a long time, but recall in the past running stability tests for 8 hrs easy, but sometimes wouldnt run for a full 24 hours.

I know its a pain to run tests for a day or more. and in your case if it runs fine 24/7 with no issues then I would say its stable.

I myself couldnt come up with a better solution, so I guess 8 hours works,

I just know there are a lot of bench junkies that could probably prime for 8 hours but doesnt neccessarily make the system fully stable. I thik this thread should be to help others see what they should be able to expect for Truly stable machines; which I hope and feel that is how its turning out, which is great

I have it 12hr prime stable. How do I upload the screenshot. I don't have a website to upload to.

**cstkl1** · 06-03-2009, 08:24 AM

billy ure right

i tested again now with my new cooling

need more vcore for prime95 blend custom 5.4gb than linx 100 runs
prime needs 1.26v, linx needs 1.25v
prime with 1.25v will fail in 2 hours.

so prime is the benchies for i7 for full stability

**trance565** · 06-03-2009, 01:08 PM

go this setup last week, new cooling i got yesterday, i'll have atleast 4-5 hours of prime when i get home from work, if i HAVE to have more, i'll do it over night. max temps so far is 73c on the first core, others are at 70/71/69, cant seem to get 4ghz to boot further than running memtest, which it will run for hours, but as soon as it sees the OS loading screen it freezes and reboots. i havent tried any multipliers past 20 as the bios says between 12-20.
also, does anyone mess with the ioh voltage? im trying not to mess with things that will destroy my system, but i would LOOOOVE to see 4ghz, even if it's just for a day or 2 before i get back to 3.8

cool man

i like the longer stress tests myself
and i have had link pax tests good and bad stress prime and of course the other way around

post some results

billy can u actually post the correct ram speeds of the ppl on ure table
some are just their rated speeds and not their prime setting speeds. it is as if u didnt even look at their screenshot

**xpatar** · 06-04-2009, 11:40 PM

@ billdavis. I would like to make a suggestion. Wouldn't be better to include also the qpi/vtt voltage in the information submitted?

8hrs. prime stable (+-28deg ambient temps)

LinX 10 passes (+-25deg ambient temps)

idle temps (+-25deg ambient)

This chip can do 4.4ghz stable @1.38vcore but temps get out of hand. Settled for this clock for day to day use.

Prime 8 hours stable:

The chip could do better but I decided to stop there due to high temps, I'm already thinking of better cooling.

Yeah, that would be helpful to see uncore voltage.

People, Linpack should be run with HT OFF. That's why you seem to be fine in Linpack yet fail in Prime. Linpack is one of those apps that are so well optimized for multi-core CPUs that Hyperthreading actually lowers the scores. Let Linpack utilize each physical core to the full extent. That'll give better indication on stability as well.
