Issue with XMP GA-990XA-UD3 and Corsair Memory 2x8GB 1866
« on: May 14, 2013, 03:20:37 pm »
Hello everyone, first time here in this forums, also I'd like to know if someone else was experiencing the same issue with mostly this setup. This is the setup running with these specs:

Proccessor: AMD FX-8350 BE
MB:             GA-990XA-UD3
Memory:     Corsair 2x8GB 1866 MhZ
GFX:           Sapphire Radeon 6990
PSU:           Thermaltake 870W
CPU FAN:   Scythe Mugen 3 Rev B
Chassis:     Thermaltake Armor+

Hope this is enough info, well, the thing was that when I started running the first time, the memory was always clocked at 1333 MhZ, I searched in the forums and got to the main topic about it, but it was only applied to AM3 CPU, and it said that from FX AM3+ CPU shouldn't have any issue. This is the topic:

http://forum.giga-byte.co.uk/index.php/topic,2515.0.html

Well, everytime I tried to turn on XMP profile in the BIOS, and then restart, the motherboard detects its memory speed as not the correct speed, and it says it will turn them to default and restart, or else It won't continue to boot. Is there anyway to bypass this detection ? One thing is that I set everything up without updating the BIOS, but the motherboard detects everything right, except the speed. Should I also update the BIOS to its latest version? Do I have to do a step to step bios revision ? Or Can I update it to its latest right away?


Thanks a lot for the time if you read eveerything (LOL)

1.Do not use XMP profiles on AMD boards as they are useless :)

2.The RAM can be set up at 1866Mhz manually in the BIOS ,no need to use XMP

Keep in mind you need to use manual settings for the RAM so you set the Command Rate to 2T as it usually goes to 1T on Auto ,which is not good stability wise.

So set the memory manually as per Corsair specification and it will work.If needed set DDR 3 voltage to 1,65V

Just look careful in the BIOS menu.
Over & Out !

Just to add to what vezina stated if you decide to update bios you can usually do a 2 step process. If there are 5 updates to your bios you can ship 1 but do 2 then after that is done and you have restarted and everything runs fine you can skip 3 and do 4 and then the same again. I always found glitches if you skip to many bios updates but others say they have jumped 5 or 6 with no problem. Me im play it safe of course you have a gigabyte board so if you do skip them all and just do most recent and it messes up it has a back up bios chip that will kick in and revert it back to the first bios it shipped with.

Hello, somehow when I tried to manually configured everything, the voltage, and speed at least, it didn't let me... Now there's the weirdest part... When I tried to boot up from manually configured, the BIOS showed the same thing, clock speed is not compatible, could cause issues bla bla bla... Then I tried to change yesterday to XMP, and it worked, everything seemed fine, It ran right away to the system without issue, been working for 28 hrs now and been running some games, heavy graphics with Crysis 3, and rthe only thing I did a significant change related to memory was to setup a RAMDisk with the new AMD software... It looks fine right now.

Thanks a lot for the responses.

PS: If someone ever encounters this kind of issue with FX proccessors from AMD, just reply this one, I will take a look too.
