Welcome to i4M and Cheers ... only quick pics handheld

Yeah there is a new driver and hopefully this will sort out the 2CF of these cards, so you should be in with a grin ... 208K on one card easy , so two should set some new levels

And of course you should join this HWBot team too

I saw your posts and they seem way low for that speed, so something not right there - not CF at least, which is why I posted the Stock runs in the first post so ppl should be able to gauge what is OK.. those are on the Abit so a P35 chipset and x16 x4 for the 2 PCIe slots and CF, but the single slot is still reporting x16 .. I had thought it might say x8 x8 in CPUz... maybe try an X38 or x48 chipset to see any improvements on the CF enable issue.

I had a drive setup for ATI GPUs (2600XT) so 8.1 was on and CF was already set... yet for the 3870X2 there is no option to enable/disable.... I did a fresh OS install on another Mobo (PCIe-2 support) but was using the 750W PSU which only as 6-Pin PCIe supplys so the Overclock section was not showing, that was using the driver off the supplied CD.

Also try the AMDGPUClock tool this apparently works, will try it once I get back to the new toys ...

Right now HD3870X2 drivers aren't clocking both GPUs when oc'd in CCC, so you're stuck with stock speeds until they fix it in next drivers AFAIK. Or try Macci's 2x display crossfire workaround and see if it works ??

ncsa

Macci's steps require disable/enable of crossfire which is not an option with the 1 card .. maybe those dip switches have something to do with it... but need the new driver to start with.

I did a fresh XP SP2 with .Net3 on X48T-DQ6, with the drivers supplied on CD and no CF
Maybe the drivers are less than 8.1?
Will play when i get home from work...

Heres what the EK waterblock for the 3870x2 looks like... Pretty nice

CF troubles solved itself, perhaps a reboot fixed it.
Back in business and 69K '03 / 30K '05 easy on stock

wtf my 8 pin connectors on the silverstone 1000OP dont fit this 3870 card, whatsup with that?

T_M

LOL.
Same with mine, i had to use a razor blade to trim the offending platic around one pin. Seems they ****ed up with the OP1000 8 pin format.
