ARGH! I cannot overclock my RAM...!!!!
AMD Athlon XP 3200+ (400FSB)
Asus A7N8X-E/Deluxe (NForce2 Ultra400 Chipset)
Kingston Hyper X 512Mb DDR SDRAM 333Mhz PC2700 (slot 1)
Unbranded 256Mb DDR SDRAM 333Mhz PC2700 (slot 2)
Kingston 512Mb DDR SDRAM 400Mhz PC3200 (Slot 3 Running @333Mhz dual channel)
Asus GeforceFX 5700 256Mb
Maxtor 120Gb HDD (7200rpm 8Mb Cache)
Alcatel Speedtouch 330 USB ADSL modem
Other miscellaneous USB devices
Pioneer 108 16x DVD writer
Lite-on 52w/32rw/52r CD-RW
Antec 480W TrueBlue PSU
Windows XP Pro
Unbranded Realtek 10/100 NIC
System Idle @ ~50 degrees Centrigrade/~122 degrees Fahrenheit
I currently set my ram to 333Mhz (166*2), and I thought that I should up the RAM speed to 400Mhz (200*2) to sync it with the CPU FSB... I relaxed the timings from CAS 2.5 to CAS 3.
When I did that, it posted okay, but when it loaded windows, I almost immediately for the BSOD...
I then took out the 256MB, thinking that because it is unbranded, it won't go to 400Mhz, but I still get the BSOD when loading windows...
When I return it back to 333Mhz @ CAS 2.5 everything goes back to normal...
I presume that the Kingston Hyper-X ram is good for overclocking, but is there something that I am doing wrong? Do I need to up the RAM voltage? Do i need to relax the timings further?
Thanks in advance!

Like you said, try raising the vdimm.

I've never overclocked generic RAM, only name-brand ones. In my experience, raising the vdimm did not have any adverse effects. Some people say that the RAM gets hotter, but I did not notice. Since I have mostly Abit boards, the highest I could go was 2.9v, and that much vdimm did not have any adverse effects.

Running your vDimm at 2.77 should be safe for most memories. First thing I would do, though, is yank the 256MB generic stick and then try posting at 400MHz with a CAS of 3 at whatever one step is above your current vDimm (probably end up at 2.6 or 2.77). HyperX should be able to take 2.77 volts no problem (if it isn't already rated for even higher, like 2.9) and the other stick should be able to take it as well. Just make your adjustments one step at a time and then test for stability."I was absolutely astounded that something like a Chee-to could become a pop icon," said Evans. "It's international. I've even seen it online on a Russian site."
