At the end of my rope here and very frustrated. My pair of 1GB memory modules refuse to run at DDR400 when used together. They are both OCZ4001024ELPE.
In both an Abit AN8 SLI and an Asus A8N-SLI Deluxe (in my system, so all other hardware besides the motherboard is identical), when either module is used alone, it runs at 400MHz, DDR400. When used together, they run at DDR200 (yeah 200, as in 100MHz clock frequency). When forced in the BIOS of both motherboards to be DDR400, the system refuses to boot and just sits there, powered on but not booting. So with these motherboards, I am forced to run my nice DDR 400 2 x 1GB modules in dual channel, DDR200 mode, otherwise system won't boot.
Bad RAM right? Well, no. When tested in an Abit NF7-S v2.0 they run flawlessly. They are immediately detected as DDR400 and they run at DDR400, dual channel.
Before I got the ASUS board, I thought the Abit was just bad. The AN8 SLI (Nforce4 SLI) would not run them together at DDR400, only seperately. When together, they were forced to DDR200. So I tried the Abit NF7-S v2.0 (note Socket A and Nforce2) and they ran totally perfect at DDR400, 2 x 1GB. So I concluded bad motherboard.
So I got the Asus and guess what? Lo and behold, exact same problem as the Abit AN8.
So two different Nforce4 SLI motherboards, completely identical problem with RAM. They won't run 2 x 1GB DDR400 RAM at DDR400 speeds. They run each module seperately at DDR400, but when used together, both boards refuse to run them faster than DDR200, otherwise the system won't boot.
So I really don't know what to do at this point. Is there some stupid setting I'm missing somewhere? I'm not as familiar with Nforce4 and the whole AMD 64 stuff as I was with Socket A and Nforce2. I'm not buying into the thought that I just HAPPEN to get 2 shoddy motherboards from two totally different manufacturers.
I originallly posted in the Abit subforum here and got no replies. I posted on Abit's (the site) forums and got 1 useless reply that basically told me to go away and post at OCZ. I also posted at OCZ's forums, which is where I got some real help and came to the idea of trying the RAM in a different board (which was the NF7-S v2.0). Naturally concluded bad board and got a new one, but now I'm back at square 1.
