Is my RAM running correctly?

Mysteri0n · May 28, 2015

Hi All,

I just have this nagging feeling that the RAM I have installed is not running at its true potential.

Specs are:
AMD fx-8350
Asus M5A99FX pro R2.0
and for the RAM; G.Skill Sniper DDR3-2133 PC3-17000 cl 10-12-12-31 1.6v

CPU-Z shows the ram running at 866mhz FSB: DRAM at 1:4 and the CAS latency at 11 clocks...
I had upped the RAM speed in bios yesterday to the closest number to 2133 which i believe was 2000 in my bios and CPU-z showed my ram running at 1066mhz but i did begin to experience some crashing issues.

Please all help is much appreciated.

Thanks in advance.

It is fine. CPUZ skews the RAM speed for some reason. I think the crashing issues are unrelated. Does it give a error when it crashes? Check in event viewer also.

No error, and not a complete crash. It'll be the program I'm using crashing. And I never experienced them crashing until I upped the speed in the BIOS.

What is the DRAM voltage at? try raising it + 0.05 and let us know the model numeber of the DRAM and what OC you have on the 8350 if any. Then we can look at getting the most performance out of the sticks we can

I just checked my BIOS and its showing my processor speed at 4300mhz, which for a 4.0ghz CPU im guessing that means its operating at 4.3ghz? as for my DRAM voltage its set to auto, and its showing it at 1.592 volts. The model number on the back of the package reads F3-2133C10D-8GSR, DDR3-2133 PC3-17000

866MHz? DDR3-1732.. so the settings are quite off.

Reset BIOS defaults or F5, then use this guide to set up the RAM:

Let us know how it goes.

Thank you gskill support. so i enabled DOCP in bios and it would not run at 1866mhz, it kept dropping it down to 1600, but then i noticed an option in O.C DRAM frequency that was 2133mhz at 1.60v already pre loaded, so i decided why not and give it a shot. So far so good, RAM is running at specs as far as i can tell.

Also thought id share this, it shows its reading the max bandwidth at PC3-12800 but on the package it shows PC3-17000, so im a little curious about that too if anyone has any suggestions?

Looks good

gskill support · Jun 1, 2015

Max Bandwidth just shows the highest value the system can boot up as without DOCP enabled. So without any BIOS changes, the system should have booted up as ~800MHz, but for whatever reason you had some stuff clocked higher, so it was actually ~867MHz.
