Are you telling us that all the DDR4 scores you've posted have been with 1.20v to the DIMM's?

Yeah....

A bit more... But closer to 1.20v than 1.90v max in my RVE...

Hi folks. What a sad day... frown.gif
Here's another update.

I thought I had pretty much got my 6950X stable at 4.4GHz (3.7 Cache) when I made this post yesterday. Hence, when I went back home after work, I *cleared CMOS and entered values that I had written down (with lowered SA voltage).

Now, the system is not stable even though UEFI BIOS settings are the same as what I had prior to clearing CMOS. frown.gif
I may sound stupid but perhaps, the system was not stable @ 4.4 to begine with. I altered voltages settings so many times during the process, I regret that I did not made a changes log and keep track of it. frown.gif

ASUS RealBench results in system reboot in 30 mins.
Prime95 throws random errors in worker threads in 20 mins.
X264 Stability V2 stops working around loop 77.

frown.giffrown.giffrown.gif

I guess I have to start from the scratch all over again. Anyway, here's my *current* UEFI BIOS settings.

Ai Overclock Tuner = XMP (DDR4-2400 10-12-12-28)
CPU Strap = 100MHz
BCLK Frequency = 100.0
ASUS MultiCore Enhancement = Disabled
CPU Core Ratio = 44 (Sync All Cores)
AVX Instruction Negative Offset = 2
Min. CPU Cache Ratio = Auto
Max. CPU Cache Ratio = 38
Internal PLL Overvoltage = Auto
DRAM Frequency = DDR4-2400MHz
Xtreme Tweaking = Enabled
TPU = Keep Current Settings
CPU Core Voltage = 1.350V (Adaptive)
CPU Cache Voltage = +0.310 (Offset) (BIOS reading = 1.315V)
CPU System Agent Voltage Offset = +0.100 (BIOS reading = 1.094V)
CPU SVID Support = Auto
CPU Input Voltage (VCCIN) = 1.90V (BIOS reading = 1.872V)
DRAM SVID Support = Auto
DRAM Voltage = 1.350V
Load-line Calibration = Level 5

1. Should I raise vcore from 1.350V to something like 1.370V ~ 1.380V ?
2. Is cache voltage = 1.315V ok for 3.8GHz ?
3. I have CPU VCCIO at default which is Auto. Should I make a change? If so, any sugestions?

Thank you!

Start with a stable base OC at a lower multiplier... use it for a while and make sure it is behaving properly. Then juice the CPU up to what it needs from there to reach 4.4 if that is your target. IMO, 1.9V input voltage (VCCIN) is low for a 10 core at 4.4GHz. But more importantly, just realize that running a 6950X for a long time, eg 24/7 at >1.35V and higher is pretty much uncharted territory.

shoot for 4.3/3/7, solidify the ram OC and build from there. smile.gif

Just keep in mind, dont attempt this now as your CPU and Cache are more important... RAM being under even 2666mhz has a significant impact on frametime in modern games.

You really want 3200mhz RAM you make sure you have nothing bottlenecking your frametimes.

What kit do you have? LMK and we can figure out which IC's they use and have a rough idea of how they will clock.

It's my understanding that DDR4-2400 with 10-12-12-28 (XMP) is about equal or faster than DDR4-3200 with CL14. (I think it's same kit as DDR4-3200 CL14 with different XMP profile).
Last time I checked with Aida64, my DDR4-2400 quad channel kit from Corsair uses SK Hynix chip.

With that being said, I just found a 6950X overclocking guide from ASUS.
http://edgeup.asus.com/2016/06/17/broadwell-e-overclocking-guide/5/
According to the article,
Quote:
For memory speeds over DDR4-3000 or if using high-density memory kits, voltages up to 1.30V may be required. Some CPUs have “weak” memory controllers that require elevated voltages to maintain stability. If possible, do not venture too far from 1.30V as a maximum.
Perhaps, I should bump up SA voltage back to 1.20V~1.25V and see how it goes. (I lowered it to 1.10V)

Even with the lowest CAS rating for DDR4 (9 AFAIK) 2400mhz wouldn't be faster than 3200mhz CAS 14. No way.

I would raise SA to 1.20v and leave it there when testing RAM 3000mhz and above. Your IMC may not need it though. I'd test 1.10 and 1.20v.

Those IC's are almost assuredly Hynix MFR. You'll almost assuredly make 3200mhz CAS 15.

You'll need 1.45v to 1.5v most likely though. No problem for MFR IC's. I ran mine at 1.520v 24/7.

All speculation until you try however. Just going on what I and others have experienced with MFR.
