ASUS has a good name, but i got alot of friends with a wide veriaty of products that sux
Like mine, why the hell would it start working on 167mhz??!?@#?!?#!?@#?!@?#!@?#!?@#!?
And the MB always did high pitched noises!
Crap I wish intel would do boards for AMD cpu's
You have "nForce3 A8N" as your board, don't you mean K8N nForce3? I can't really find anything on a A8N but there's alot of reference to K8N nForce3, can you give specifics of that Motherboard? As well as the RAM you're using?
EDIT: I found your problem, it seems it's ASUS related (go figure), that running the newer ASUS BIOS on Socket 754 Motherboards, if you use 2 Sticks of RAM that are Dual-Rank (Double-Sided) it forces you to 333MHz DDR. With an older BIOS, you can run DDR400, but may cause instability. Some people claim if you use different slots, it runs DDR400, but it seems it's a ASUS problem.
It might just be it because I"m using a newer BIOS version.
Crap what should i do? Load the old "Instable" BIOS settings ?
(Yes its my bad I Use K8N)
How can I know if my memory is double-side?
And where can I see that when I'm buying new ram???
Try the older BIOS and see if it's stable, it may be. You'll know it's double-sided if you have RAM Chips (little black blocks) on both sides of the chip. Most new RAM is Double-Sided (Dual-Rank) so don't worry about that.
