B-Die DRAM OC issues

[NemesisChild]

I easily OC'ed my 2x16GB 3200 CL14 set to 3400 CL14 simply by just increasing the DRAM voltage to 1.375v.
You have a good board and memory chip, so basically the CPU IMC would be your major limitation.
Do manual settings, do not use XMP and don't mess with the secondary timings.

Did you try Maximus Tweak mode 1 or even mode 2?

Yup, thought mine could do aswell.
For now, all previous bootable set-ups, unfortunately, were unstable, so I didn't achieved any stable result, exept one I'm testing right now.
maximus tweak is on 1

So, I'll mark it up: 3200MHz, CL14, Command rate 2T, 1.4V, vSA+IO 1.20V

Though, I was unable to force the thing boot with 1T command rate, only in stock 3000MHz. In any other OC case, it just stucks at RAM initialization with bF (6F) code.


P.S. What's the better option for ram oc test? For such purpose I've always used AIDA, but I can see people utilizing this "testmem" thing....though I don't really like it, looks glitchy. But if it is more effective, why not.

According to G.SKILL the maximum rated memory speed with a 16GBx2 kit for the Z370 Maximus X Hero is 3733MHz CAS 17. http://www.gskill.com/en/product/f4-3733c17d-32gtzr. I'm sure this is at the 2T command rate as well.

These G.SKILL memory kits are tested at XMP for each particular board, not just a general test with a particular chipset like everyone else does. The QVL at G.SKILL appears to be the most accurate one compared to anyone else.

They also have these ones http://www.gskill.com/en/product/f4-4000c19d-32gtzsw
I suppose, they use identical chips for all those low latency, high speed kits

I was able to boot with 1T command rate only at 3000MHz. No luck with any other option

hello here is my specs

8700k @ 5.1 ghz @ 1.296 v -manual
Asus x hero z-370 wifi - bios 1602-latest
16gb ( 2 x 8 gb ) g.skill (Trident-z RGB ) 3000 mhz cl-14-14-14-34 1.35v

i have my ram over clocked to 4000 cl-17-17-17-37 1.4v vccio @ 1.2v / vcssa @1.2v

100 % stable in asus real bench , prime 95 , mem test 86 , gaming

i can run 4133 18-19-19-39 , 4133 cl-19-19-19-39 , 4200 cl-19-19-19-39 it starts to **** on me around 4200

pretty good for a g,skill rgb 3000 cl-14 samsung bdie kit im running 16gb though . yes there samsung bdies typhoon reader says so .

if u need some help i can help yas ! i wouldnt go past 1.2 ish" vccio / vcssa though over time .

For that P95 stability - is that an AVX build or non-AVX (26.6) - and if the former, what is your AVX offset, if any?

....you don't just buy a 3000 rated kit and stick in the 4000 timings and away you go...we all wish that...

A bit off topic, but funny thing is, i 'downgraded' my T-Force Nighthawk 16GB 3200mhz to a TridentZ RGB 32GB 2400... but i've oc'd it to the XMP specs of the T-Force, and tweaked it so its actually better timings. Tested the hell out of stability, it's rock solid too.

Your SA voltage is high. I've tested numerous memory configurations. Best for me has been VCCIO (1.15v) and SA (1.20v).

Keep the CR at 2T for better overall stability. You only get a marginal hike in performance with 1T anyways.

I'm giving up!
I was unable to stabilize my ram. Whatever I did, sooner or later, eventually, it failed AIDA stresstest. And I've only tested system memory - no CPU,FPU or cache stresstest.

First I tried it with both RAM and CPU overclocked.
Then I returned the CPU to stock settings, reset everything, leaving only RAM.
Tried 1.35v, 1.4v, 1.45v, 1.5v respectively, each time I've raised to 1.10v, 1.15V, 1.20v SA/IO
Then I've set SA and IO to default 0.95 and 1.05v, and tried all over again with vRAM.

Whatever voltages for SA, IO and vCore I use (aswell as CPU clock), I have it like this:
1.35v - unstable
1.4v - unstable
1.45v - unstable
1.5v - awfully unstable, crashed in 3 minutes.

Plus, I've managed to boot with 3466MHz at CL14 with 1.45V vRAM, but still not stable in AIDA.

Nothing worked out. At all. AIDA always gives out an hardware error.

BTW, I've never mentioned exactly what ram do I have.

And that fact, that I can't achieve literally anything at all, frutrates me even more.

I personally have never used AIDA64. Have you tried RealBench?
