Start with making proper basics...
Changing things from a unstable basis is not the way to go. Too many variables then.
And sure, disabling a few cores help. But you could just as well have bought an 6350 then.
Can you post full info on your 4.5 clock? fsb, multi, cpu-nb, ht, ram and all voltages.
We can then look on where to start bud.
Well, as far as anything past 1.4v I will freeze almost instantly regardless of clockspeed (like 1-2 seconds in to a test). I would worry about getting stable if I could get past that issue first.
Running 4.8 on 4 cores was just a test to see if it was clock related. What was interesting is that I did not insta-freez while on the 1st 4 cores, but as soon as I changed to 1 core per module I was back to insta-freezing. It was speculated that maybe one of the latter cores may have higher leakage, but If that is the case then voltage should solve the issue. And apparently it doesn't.
So it is my belief that the 3rd module is weak. Only way to tell I guess is to put the chip on to a loop.
It was also speculated that temp may be the only issue, however I do not believe the chip is hitting 70C in less than 2 seconds (faster than software can report the temp). I fail to see why cores 5-8 would overheat in 1-2 seconds, when cores 1-4 do not. It was speculated that if one of the cores from 5-8 were leaky, then maybe that would explain why those cores temps would skyrocket in comparison to the first 4 cores. But I'm not so sure I can go with that. I never even see 60C before it insta-freezes.
Here is my last test at 4.5 Funny thing is IBT failed. Then I upped the CPU/NB voltage and got better results with IBT, but can't remember how many passes. IBT is new to me, and I sometimes question its reliability. (Sometimes you pass 20 passes, sometimes you don't) Same could be said for any software I guess, if your not actually stable hehe.
Multi only, RAM settings auto.
CPU/NB 2200 1.2v
HTT 2600 1.210v (I believe)Edited by pshootr - 1/13/15 at 5:51am
