Prime test and Q6600 multiplier

[htoonthura]

Hello there,

My Q 6600 vid is 1.325. It is high, i know. I got it stable at 3.2 G for months. now i go to 3.4. My vcore voltage in cpuz during prime test is between 1.4 to 1.44 V. Anyway, it is stable at 3.4 g with no error for 30 minutes. Then , it drops to 6 multiplier during the test by itself . it keeps running the prime test with no error, of course. Why does it happen? I have disabled all the c1e , eist in bios. Yes, temperature is 55 to 65. What is going on and how do i fix it. my motherboard is Gigabytes p 35 ds3 L. i am happy with what i got , but i want to solve this problem with your help.

Thanks.

I think its throttling when it hits 65 degrees (specially if thats from the tcase sensor and not the per core readings).

ur processor is running too hot. 55 to 65? are these idle and load temps?

load. during prime test.

Is that the "CPU" temperature or the temperature from the cores? If its the general "CPU" or "tcase" temperature well then your cores are running at 75-80 degrees which is close to burn out levels if sustained which it is during Prime95.

lol!

u do not even need to know you vid to get 3.6ghz!

lol! vid! i love that the newest fad on the oc forums

6 months ago it was bottlenecking now its vid

you need 1.44-.146v as posted by me in first week of augest 07and still true today for a q6600 g0 regardless of vid! as posted: http://www.tomshardware.com/forum/244351-28-61ghz-1ghz

i did not want to tell eveyone back then the magic range was 1.44-1.46 under full load, while less voltage may very well work - i have never met a q6600 that does not run 3.6ghz at 1.45v

the 1.45v has been confirmed over and over - forget vid and work on memory timings?

Strange. My Q6600 the first pair of cores can handle prime95 small FFT for hours on end at 1.4volts by the second pair isn't stable until 1.475 volts.

But yeah that chip seems to behave strangely at times when overclocking.

It is the hottest core temperature.

Thats still pretty high. Your processor is probably throttling itself. Try going back to 3.2ghz and see if the behaviour persists. If not its definately a overheating problem.

I do not think heat is the issue. 71C is the upper limit. besides, i see people running over 71C with no such issue.
