Help with RAM issue
Posted: Tue Sep 27, 2005 1:09 am
In my new system I got 4x512 Corsair Value Select DDR400. But, when I start my system up it says that the RAM is only DDR333. I have checked the RAM by opening my case and they have official looking stickers saying DDR400.
I tried updating all of my mobo drivers and stuff but nothing happened.
2GB Corsair VS
200GB samsung spinpoint SATA
Please help. Thx,

I don't know if this is still a problem with newer systems, but a while back some memory controllers couldn't reach ddr400 speed with 4 memorysticks in the system. This can be easily tested by pulling two sticks and seeing if that changes anything.
The other thing to try is to check your memory settings in your BIOS and trying different setting combinations.

I'll give it a try. Thanks.

Yep, this is a huge failure on AMD's part. All the Athlon64s have integrated memory controllers but the old memory controllers can't handle four RAM sticks at DDR400 speeds. If you have a dual core Athlon or the latest stepping of the Venice or San Diego cores this won't be a problem. Other than that though you're pretty much stuck. Well, you could probably overclock the system bus/HTT and drop the CPU multiplier and then it would run at the speed you want but that is a hack that AMD shouldn't have made necessary.
