But failed in OCCT large data set within 15 min.

I ignored OCCT, and begin playing Battlefield 1, randomly crash freeze my PC within 10-30min , sometimes after 40 min.

I increased the voltage to be able to pass 3 hours on OCCT large data set without a report with error detected, and when passed it, my PC did not freeze or crash anymore, for 2 months in any games or any application, even 5 hours non stop in Battlefield 1.

my conclusion is that people are afraid from OCCT because it gives them the reality about their CPU OC capability.
OCCT large data set 3 hours (according to OCCT website) without error -> CPU OC perfect stable (I am talking only about CPU, not ram or cache OC).

this is my opinion.

With my 6900k i didn't run any software.
I put occt large data set 3 hours 1.271v 4.2 ghz, i passed without error, cpu oc done.
1 month didn't have any crash or freeze in any games or application, occt is the king


I don't have any issues with stability, nor have I ever used OCCT. Sounds like more a case of not knowing where and why to apply additional voltage. I also have 130 hours in BF1 on record with CPU stability tested in RB.

The cache yes, I may increase it a little more.
About the vcore do you recommend the one and only adaptive (1.295v) set and no offset or it doesn't matter?
About the Gsat, I did 14400 s (4h) in two run.
First one before I was starting with the core (I did the ram before all, at 3200 cl14, 1T and 1.35v)

And then, when I've finished with these (original) voltages:

Core clock = 4.3
Cache clock = 3.6
Highest CPU package temp during stress test = 66C on OCCT
VCCIN = 1.880v
LLC = 6
vCore = 1.285
vCache = 1.200
VCCSA = 0.976, 0.020 offset
VCCIO = 1.075
RAM clock & timings = 32GB 3200 14-14-14-24 1T
vDIMM = 1.350V

I first did 8h realbench and then another 4H of Gsat.

Starting from these values & voltages I wanna try to OC to 4.4ghz, 3400 ram (same timings cl14) and 3700 uncore.
What order do you advise me to start with and eventually what vcore, ram and cache voltage?

Trying right now with OCCT for the 4.4
After a few adjustments I have now 1.92v vccin, 1.1 vccio, 1.24v cache and 1.364 vcore..
Tried with less but I've had errors (no blue screen), with 1.348 I got an error on core 3 after 18'.
Now it's been 40' and running, max package 73C.

Finished stress testing with VCCSA = 0.960V and VCCIO = 1.024V for new memory. 4 hours of GSAT and 700% of HCI MemTest passed.

A quick comparison with previous memory. FireStrike score was slightly increased as well.

Did 1T require additional voltage or tuning?

I've not been able to get there, but I've only tried a few times. Eventually, I get a GSAT error.

Hi cekim

If I'm not mistaken, are you not running 128GB set of memory ? If correct, tuning those modules would be quite different from small ones like mine (32GB).

Any tip without increasing the vcore?

Nice score, what cpu & cache clock?
My memory will always reach a higher write above all but I can see yours is better in write
And I still don't get how come your (expensive) 6950K's always shows a significant memory bandwidth improvement (well, some of them)
Still need to figure if it's just a better IMC or some settings / voltages also can make a difference. rolleyes.gif

Edit:
See the clocks, my bad
Will try with the same clocks soon thumb.gif

6950X with extra cores and increased cache help to score higher in Aida's memory benchmark.

Correct. TridentZ 3200CL14 128G

1T so far has been a no-go. I've been moving things around though, so I'll have to try again.

How are you adjusting your settings? Are you using Ai Tweaker or directly in your BIOS? I don't have AI Tweaker installed because it's more trouble then it's worth but I'm not exactly sure where in the BIOS those changes should be made. Were running almost identical systems except I'm not sure if your using 32 or 64GB of ram. I have 4 X 16 GB sticks. If possible can you give me a screen shot of where your making your adjustments.
