I have read both in Anandtech and Tomshardware.com that the DFI NFII Ultra is the best motherboard out there and is good for overclocking. So, I went ahead and got myself one. Because I am new at overclocking, I didn't want to mess up the processor or motherboard. So, I didn't do anything extreme (I think...). Here's what I did:
CPU clock: 210 Mhz
FSB = 2 x CPU clock = 430Mhz (right?? I'm not sure about this)
CPU ratio: 11
DDR ratio: 1:1
CPU voltage = 1.75V
Chipset voltage = 1.8V
DRAM voltage = 2.8V
System specs:
DFI NFII Lanparty Ultra mobo
AMD XP 2700+
ThermalTake Volcano 11 heatsink and fan
Single piece of 512 Corsair XMS DDR 3200 with heat spreader (CAS 2)
GForce2 GTS 64MB
I didn't mess with the AGP speed or the memory timing. But, I realized that with the overclocking specs above, my PC is very, very unstable. The motherboard won't post if my CPU clock went above 215Mhz or if I set my DDR ratio above 1:1 ratio. I have read ppl achieving about 230Mhz and 5:6 ratios on the same CAS 2 memory I got. I have tried lowering my multiplier to achieve FSB above 215Mhz but Windows just wouldn't start and I would get a lot of error messages such as "hard drive not found" or "error reading file" , etc. Sandra Sisasoft Burn-in program will stop responding and quit by itself. Can anybody tell me what I'm doing wrong here? I read an article at Tomshardware that chips can be overclocked approx 30% pass it's rated speeds. 30% pass 2160Mhz for XP2700+ would be somewhere near 2800Mhz. But I'm not anywhere near!!
Would appreciate it if someone could advise me on what settings to change. Also, if I were to change the timing for a single channel CAS 2 memory, what should I set them to?
