post #1741 of 7480
@Jpmboy

Let's see if you've taught me right, machine has been running fine since I last showed you.
But today I had the urge to run x265 Benchmark again, now I've past it many times days ago, but today it hard locked.
I adjusted the SA Offset and well it's passing again, I actually lowered in not increased it.
So I'm guessing like you guys said to me a while back it's a hard thing to test stability in, am I looking in the right area?

yeah so, x265 puts some demands on a few voltage settings that other tests/benches do not seem to pull as hard from . x265 hits VCCIN hard... this supplies all other voltages - vsa, vcore, vcache.. etc - so most times increasing vccin or reducing vdroop will fix x265. Try setting vsa back to where you had it and raise vccin by either method. Depending on how you are running x265 (p-mode and more than 4 threads for example) it will load the ram and cache pretty hard... so vcache can stabilize it too. VSA really supplies voltage to several structures so it may be giving a fix that can be solved more directly. thumb.gif

So I did learn something woohoo... biggrin.gif

This was the run I did that passed just then, the same run failed with the higher VCCSA



The SA was set at +0.051 when it failed.
I'm still not sure what LLC to use, currently it's 6.
The VCCIN is set to 1.920v in the BIOS, but on idle it's 1.936v under load it'll drop to 1.904v though.

Edit:
Here's a few screenshots of my BIOS settings.

erm.. you are setting adaptive vcore very strangle. Change this to "auto" in offset and enter the necessary vcore in the adaptive field.(eg, the Total voltage needed at load). For cache - again - it's set incorrectly. Either change 0.001V to Auto for cache, or figure out what offset is needed to achieve the necessary vcache for the cache freq you are using.
Try this and let's see.

Cool, will change that.
So LLC 6 is fine, and the VCCIN voltages are ok?

If I set the vcore to 1.265, it registers as 1.271v in CPU-Z, I'm guessing thats to do with the LLC 6.

nope - cpuZ is reading VID on x99. Use AID64 to monitor voltages. LLC 6 is fine, VCCIN is fine... you can go to 1.95v if there is instability. some CPUs need high VCCIN (eg when adding vcore is not fixing the problem)

Yeah I had a spaz out then after adjusting the settings you recommended, it's hard locking at 33% during x265 benchmark (same settings as the screenshot), I'll try upping the VCCIN to 1.950, it reads higher that the set voltage though.
So I'm guessing 1.265v for 4.2Ghz was ok, but I need voltage somewhere else.


Edit:
Maybe I was being to liberal with the voltages.
Cache I set to offset +0.100 (3.4Ghz), VCCIN 1.950v, though sometimes it reads 1.968v, but not under load.
Passed x265 now, not perfectly with all the FPS's the same, but a pass none the less.
It's certainly given me something to work with.



During the x256 run AIDA63 Sensors.

Are there any good comparisons/benchmarks around between the 6850k and the 5930K? All the reviews I've found so far are for either 6800k, 6900k or 6950X.

@Jpmboy

Getting my stride on now.
I increase the vcache from +0.100v to +0.110v, got a more consistent score on x265 Benchmark.

Nice, I can't get my cpu cache to work on adaptive myself so I have it locked at 1.310v for now.
