GIGABYTE GA-990FXA-UD5 and Corsair XMS3 8GB (2x4GB) DDR3 2000 MHz (PC3 16000)

carlitoswayec · Sep 24, 2013

Hello,

I have setup a PC with a mainboard GIGABYTE GA-990FXA-UD5 and Corsair XMS3 8GB (2x4GB) DDR3 2000 MHz (PC3 16000) memory sticks. I ran a 3DMark 2011 test and noticed that my memory is running at 533MHZ (?). My CPU is an AMD FX-8320 Eight-Core Processor Black Edition AM3+

Is there anything I need to manually setup in the BIOS to achieve the proper RAM speeds?

Please consider I know about computers and stuff but I'm not expert, which is why I come to you

Thank you for all your advise and recommendations.

Regards

Check in your BIOS for DOCP (DRAM OC Profiles) and with your CPU I'd try setting to 1866, sort of doubt they have a 2000 profile but they might)

Tradesman1 :

There is a 2000 profile (and even higher). I tried setting it up like that, (and setting voltage to AUTO), saved BIOS, restarted and it booted but with a warning message (not the normal image from Gigabyte when booting) regarding error and instability on boot and that if i wanted to continue or go to BIOS setup. I didn't want to risk going past that message and went back to BIOS and loaded default settings.

Much appreciate your suggestion or anyone elses. Thanks.

Try doing the the same, even trying 1866 and then manually raising the DRAM voltage + 0.05 and let it go

Tradesman1 :

When you say "let it go", you mean, let it boot despite any warning message?
Sorry if I am overzealous, I just want to be sure I am understanding correctly, hehe.

Thanks

Yep, it will go back to defaults if things aren't liked

Tradesman1 :

It would seem it didn't like it , because new settings did not stick.

I am starting to wonder if the mainboard simply doesn't like these memory sticks, which I find disappointing, since they are supposed to be a good brand and all.

Also, I took notice, that the ram sticks appear to be plugged into the ram slot #2 and #4, not sure if that has anything to do with it. I did not assambled this computer, a friend helped me, as I am a handicapped person and can't get down and do it myself (with more attention to detail, perhaps

).

Try them in 1-3 at and just see if it boots with no changes

Tradesman1 :

I am not sure when I'll be able to hook up with a friend to help me with this, in the meantime, perhaps this text file with detailed information about my computer, that I got with cpu-z, might come in handy. https://dl.dropboxusercontent.com/u/19740326/cpu-z.txt. Take a look if you can

Thanks!
