990FX Extreme4 with 16Gb Adata DDR3 2000 problem.

[Quietruck]

I have installed 16Gb of Adata DDR3 2000 XPG Gaming series V2.0 on this board. Along with an AMD FX-8150 Black Edition (Bulldozer), I have read that I should be able to achieve 1866Mhz speed. And even on these very forums I was told I could achieve 2000Mhz with ease, with a little overclocking. But have only been able to reach 1600. With multiple attempts to OC the board freezes and reverts back to 1300 default. I have tried to manual set timings to ram specs for 1866 with same results. Any settings suggestions that are proven to work that would allow me to reach 1866 or even 2000Mhz would be greatly appreciated. Thanks

Well, I only find that these are available in 2Gb and 4Gb sticks so that must mean you have four 4Gb stick installed, right?

I ask because I cant find much info other than Adata making an 8Gb kit consisting of two 4Gb sticks. Nothing of relevance on their website either. Most I can find on the 8Gb Kit is 9-11-9-27 1.55v-1.75v.

Linkage please to something resembling a product page so I can read what they're spec'd at. My numbers above are questionable as they originated from a 3rd party site and then only more a press release than factual data.

Here is the info your looking for. I have 4 sticks of 4 Gb each installed. Newegg.com - ADATA XPG Gaming v2.0 Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2000 Desktop Memory Model AX3U2000GC4G9B-DG2

OK. Just what processor is installed? The 965 listed in your System Specs or the FX-8150 in your original post?

And is P1.50 the current BIOS revision?

AMD FX-8150 Black Edition Zambizi, sorry about not updating my system specs. My bios is the lastest L2.11A as described on my Bios screen.

[Quietruck]

I beleive that bios is a beta version. That may be part of my problem. I can revert it to the lastest 2.0 version if will help
At that time I was attempting to update my bios I could not seem to find a full list of non beta updates. but that was only a week ago. Most of the time I have owned this board it had the bios version it was shipped with.

For 1866 what memory voltages have you attempted with?

And out of curiosity what are the timings set at while running 1600?

Better yet, can you post a screenshot of CPU-z showing the SPD tab?

[- wardog -]

Sorry. Stay at 2.11A for the time being.

[Quietruck]

There you go wardog.

Sorry wardog I already went back to the non beta version 2.00 of the bios. Hope that doesn't mess things up.
