FX-8320 and 2133Mhz RAM stability issues

post #1 of 8
Thread Starter 
Hello guys. Rig is the one from signature, if you are too lazy:

CPU: FX-8320 at 4.0Ghz @ 1.4V
MB: ASRock 990FX Fatal1ty Killer.
RAM: 2x4GB Mushkin Redline 969969 2133Mhz

I have set the RAM to work with Profile - XMP 1.2, which sets the DRAM voltage to 1.65V.

Timings are 9-11-10-28-2T-38, 300ns, 32tfaw.

I have run for ~1 hour MemTest64 at maximum RAM and 7 threads.

No errors found.

But when i start playing games, i get either NTDLL.DLL faulting module and game crash OR AMDKMDAP driver hangs and recovers.

Also, when i try setting up the RAM at 1866Mhz with 10-10-10-30-2T at 1.65V, sometimes it would boot, others it will not.

CPU-NB and HT Link Speed are at 2200Mhz and 1.25V/Auto.


Link to a related thread, where i thought it was Widnows/Driver issue:

I haven't seen anyone running ram successfully at that frequency on AM3+. I may be wrong.

Its a little harder to get 4 sticks to run at 2133 and beyond. It just takes some tweaking to get it to work. Have you tried increasing the voltage on the NB to 1.35v.

 

I ran 2600mhz sticks on my crosshair for a while it just needed a lot of tweaking.

Its 2x4GB, not 4x2GB, i run it in Dual Channel (slots 2 and 4).

By NB voltage, do you mean CPU-NB or NB, as the first is the IMC, while the second is the Chipset.

CPU-NB IMC as the cpu is the limitation.

Ok, CPU-NB at 1.35V does the trick. I will try lower later.

The question is why its not stable at 1.25V, since stock IMC is ~1.15V.
Still, quite big voltage jump. Big difference from the Phenom II 960T i had, i ran it at 2800Mhz CPU-NB @ 1.4V with 1600Mhz 9-9-9-24-1T @1.5V RAM.

From what i know, the CPU-NB has to be AT LEAST double the RAM speed (106x2=2133mhz), but CPU-NB = 2200Mhz. And was the correlation between HT Link and CPU-NB 1:1 supposedly?

I take my words back. CPU-NB even at 1.425V and i still get driver crashes at XMP 2133Mhz.

EDIT2:

Tried with CPU, CPU-NB and RAM voltage increasing, all on the same time, tried 1.45,1.45, 1.68V, still happened. Went and used the XMP profile and changed the frequency to 1866, lowered RAM voltage to 1.5, everything fine and dandy. Not stable timings or what...

Ok, problem solved.

Turns out, my motherboard supports RAM speeds of 2000 and 2450, but NOT 2133. Go figure.

Set the FSB to 216, used the 1866 setting with the XMP profile (now 2012Mhz), and it runs without issues for 2 days straight.
