My system is : -

opteron 165
4 x 512 geil ddr (2 x 512 @ cas 2, 2 x 512 @ cas 2.5)
dfi ultra-d mobo
ati x1800xt


I have been able to overclock the chip to 2.1ghz but my system seems to freeze, the cursor freezes and I need to reboot. I'm using systool to o/c the cpu while constantly stress testing i'm upping the fsb by 2-4 clicks at a time and sometimes only waiting 20 seconds inbetween each increment. Is this too fast?

I'm concerned that my ram will let me down, does it matter if 2 sets are different to the other 2 sets?

Another thing is I'm using the stock fan that came with the opteron and I also kept the stock cooling paste on the bottom (I didn't wipe it off and put arctic silver on) will this affect it much?

I have read the beginners overclocking sticky but I really don't get what you need to do to the ram. As I increase the fsb obviously it automatically increases the memory clock, but I don't know what kind of limit the ram will have and I don't know what to do with the timings. The memory tab in systool is very confusing and I'm unsure if I'm looking for lower or higher numbers (is cas 2 better than cas 2.5?)
 
You need to lower your HTT multiplier to 3, otherwise by raising the FSB the motehrboard chipset is becoming unstable (Must never really be above 1000mhz).

Is that the cpu/fsb frequency ration on a dfi mobo?

It's currently set to auto but has values of 1x 2x 3x 4x etc
 
wait, lol, that's actually the CPU multi, my bad!

It should be called 'HT' or hypertransport something or other and should give you the option of auto, 5x, 4x, 3x, 2x, 1x, and possibly 2.5x + 1.5x
 
hehe I just checked again and yeh the cpu/fsb starts at 4 and increases in 0.5 increments

The only other one could be LDT/FSB which starts at 1, 1.5, 2, 2.5 up to about 5

Is that it you think?

I can't see anything with an HTT or HT in it
