Hi,
I had a quick play this afternoon with my 1.8A and got the following after about 30 mins of tweaking.
FSB 133MHz, CPU freq = 2.4GHz
Vcore + 10%
CPU
RAM 3:4 = memory 354MHz
CAS 2 timing
Tried 133 FSB at spec Vcore first off but pute wouldn't boot so stepped back down to 120 and worked up from there.
Using Corsair 2700 256MB memory and Akasa 670 heatsink (a little bit better than stock heatsink, it doesn't warp the board and is easy to pop on and off).
Processor did 10 loops of sandra arithmetric/multimedia benchmark with no problems at +10% Vcore, at +5% arithmetric bombed out a few times. CPU temp was 41degC max.
With my gainward ti4400 at 300/601 I got ~11500 in 3dmarkse.
Interestingly, at stock CPU speed of 1.8A, memory 266Mhz, upping my graphics frequencies from 280/550 to 300/601 only changed 3dmarkse result from ~9200 to 9500. When I then upped CPU to 2.4GHz, memory to 354MHz, I got the big increase. Hence, I am concluding that in a "rough and ready average sense" I am CPU limited with the ti4400, which actually makes me very happy I didn't several the extra on a ti4600, spend the extra on a faster CPU in a few months.
The Gainward Ti4400 is a great card for the money, was easy to get to 300/601 seems very stable at that speed.
Stepped back down to "normal" frequencies for time being as I need to install a load of apps on this new machine.
Cheers,
WittyNewt.
