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

Managed to finally get it OCCT 4h stable at 4.4Ghz with 1.37v (cache 3.6 for now)
I think the temps are OK thumb.gif



Next step is either the cache at 3700 or the ram at 3400 though I don't quite know which one first rolleyes.gif

For the cache at 3700 I've used 1.28v and here's the 2h aida64 cache first:






And then an over 800% coverage with Hci 5.0 (it took me over 6h to do it):





Now I'm gonna push the ram some more, starting with an easy 3400 at 1.4 or 1.45v

And only a small improvement so far:





Maybe it's even enough for a 6 core coolsmiley.png

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.
I'm currently away from home.
There's nothing special I do with BIOS settings. I always adjust settings in BIOS. I don't like relying on Windows software for adjusting BIOS settings.

Previously, I was using 32GB Corsair Dominator Platinum DDR4-2400 10-12-12-28 (at 1T) (SK Hynix MFR) since when I bought 6950X in June last year. It took me couple of weeks to find stable settings with those Corsair set. Recently, changed my memory to G.Skill TridentZ DDR4-3200 14-14-14-34 (at 1T) (Samsung B-die, I think), and the G.Skill is pretty much plug & play. VCCSA and VCCIO are not much different from those previous Corsair. In fact, VCCSA is slightly lower.
Below is my 24/7 overclock settings:
Core clock = 4.4GHz
Cache clock = 3.7GHz
Highest CPU package temp during stress test = 69C (during OCCT)
VCCIN = 1.95V (I have not tried any lower, to be honest)
LLC = Level 5
vCore = 1.360V
vCache = 1.250V
VCCSA = 0.960V
VCCIO = 1.024V
RAM clock & timings = 32GB DDR4-3200 14-14-14-34 1T
vDIMM = 1.350V

With settings above, system is rock stable and has passed:
- 4 hours of GSAT
- 8 hours of OCCT
- 4 hours of ADIA64 cache stress test
- 700% coverage of HCI MemTest
- 8 hours of RealBench

Depends how capable the kit is with lower sub timings. Miniscule differences in reality

Here is a quick cinebench R15 (4.4 core, 3.7 cache 3200 c14 ram):






I tried a couple of h ago to test the ram at 3400 (same above clocks) maintaining the 14-14-14-34-1T timings at 1.40 (dram volt.) and then at 1.42, 1.44 and 1.45v (last one with a little 30mv vccsa increase)
Didn't manage to get rid of gsat errors however.
Same 4.4 @1.37v and 3.7cache @1.28v
Any hint to stabilise it at 3400 without any higher than 1.45v?

3466 seems to be working without any issues on mine at 1.45V. Might try that as well.
Adjust the timings like 14-15-14-34-1T and you will need much lower VDimm.

Looks like a re-hash of the same "leak" that's been around for a few weeks.

Don't worry, it's the same thing I was throwing at JP on another thread a week ago (got confused which thread with this second "leak" post biggrin.gif)
We're wishing it will be true, June/July release will work in really well for me... thumb.gif
