Well, the one has survived. it's running stably at 900 core right now. I'm gonna bump it a little more tommorow, but it's definitely sleepy time for me.

Not getting much of a bump in 3dmark though. I can't believe i'm saying this, but it's probably my CPU .

I noticed that with most of my nvidia cards. Overclocking cpu, big jump in score, overclock gpu, not so much....

[alexgheseger]

Ok, so the max reliably stable core for me is 875, and i get it at 1.333 V. Higher voltages yield worse results for some reason .

Anyways, here's a crysis bench @1680x1050 all high DX9:


Not bad for a single card, especially considering it is only 2 FPS short of what i got with Tri-fire 3870's

ooh nice, i will have pics as soon as the UPS man shows up

Would you guys recommend after I get Vista Installed, Chipset Drivers Installed, Then go to ATI's site and get 4870 Drivers?

[vis213]

get them now so you'll have them ready
if possible go ahead and uninstall your current drivers and use a driver cleaner to clean it up

man, i just ordered a duorb ($35 at DirectCanada) for my incoming 4870...i think i'll be good if i have reasonable case ventilation, AS5 and all the ramsinks

in all the reviews i read it beat the vf1000 and the only complaint was higher sound levels due to the lack of fan speed control

i also bought a TRUE w/2 fm121's

but it makes me wonder if i should have gone water with all the money i just spent on copper and fans

There have been several reports of the Duorb not being able to handle load temps of the 4870.
Search Rage3d, and Guru for a couple of examples.
