Bad mobo and/or RAM?

Hello, recently I overclocked my computer and I was using an ASUS A8N-SLI (s939) and instead of setting a RAM divider, I set my frequency to 200MHz.

I was going to help a friend overclock his machine since he seemed interested but I ran into a problem. I was going to set the RAM divider to 1:2, but I didn't see the option. So I figured his mobo was like mine and I'd just clock down from 400MHz to 200MHz (we both have PC3200 DDR400), but the max setting was 333MHz. Odd I thought, most mobos should be able to go higher.

So I opened up CPU-Z and the DRAM frequency read 200MHz.

Now maybe I am wrong, but a RAM divider on a non-overclocked system should be 1:1, yes? So it should of read 400MHz, meaning he's been at half the RAM speed he should be getting?

Or I am reading something wrong? His RAM is from a Gateway and his motherboard is a Foxconn WinFast nf4uk8aa.

Any help and suggestions? He has two RAM modules, both 512MB and they're both from the Gateway (which came with the Gateway) and so I know ones not clocking down the other because it is slower. I'm either thinking the RAM is going bad but I don't know if that would be testable with memtest or the motherboard is going nuts (which his computer does act... badly at times. Random outages where he has to reset the CMOS, etc)

He's got a pre-built computer. These companies pay extra to have their BIOS's A) made unoverclockable, and just as importantly, B) dumbed down alot, so their average user might have a chance at understanding it. I would guess that most of them don't have "200 Mhz" RAM settings, just "Auto", which is 200 Mhz, and then the slower settings.

Check the SPD tab in CPU-Z, to make sure his RAM is actually PC3200. Also, download and run MemTest HCI, which is much better at catching errors than MemTest 86.

Mmm what? I never said anything about pre-built, only the RAM is from the pre-built. Everything else is bought and put together by him.

Edit: I'll have him do that SPD thing and I will do memtest HCI if it turns out I should have him run it.

All PC3200 RAM runs at 200 Mhz. That's the speed it's supposed to run. As far as his system not being completely stable, start with replacing the motherboard's battery, and testing the RAM.
