sabertooth 990fx 2.0 memory issues
hey guys im having a little bit of trouble getting my bios to utilize all four sticks of ram i have. it will only recognize 1 running at 2133 and 2 at 1866 and below any suggestions guys and help will be greatly appreciated
sabertooth 990fx r2.0 latest bios
patriot viper xtreme 2133mhz 16gb 4x4
coolmax 700 wat psu
thanks in advance guys
Pretty typical for all AMD chipsets. They don't like running high speeds in 4 slots. You can try bumping the NB and mem voltages a bit, and make absolutely sure that they're running 2t (most AMD chipsets seem to default to 1t, but the great majority of memory on the market is rated with 2t set).
I have 32GB in my Sabertooth and lazily I set the memory at 1800mhz for all four slots and its 100% stable. You might be able to sneak it up but I doubt you will get it running all four slots at 1866mhz. If its any consolation its almost no difference anyways.
i still cant get it to utilize all for sticks = /
I had a similar problem a couple of days back, were my RAM was causing my P.C. to blue screen. Asus Released a new bios update a couple of weeks back fixing some stability problems that might also fix your problem. Find the latest Bios update here: ASUS - Motherboards- ASUS SABERTOOTH 990FX R2.0
Have you tried 1333mhz and 1600mhz just to see if it will POST at those speeds?
I have read/heard that the asus amd boards can be VERY finicky with ram. And i've heard all possible speed/amount combinations work on some boards for folks but others not at all.
USUALY the 4x4 setups all speeds work well .... for shure @ 1600 they do as thats what mine can do now vs couldnt do on my 1090t.
Thought thinking of it, I think sky even mentioned about him having a hard time to run anything over 1866.
