mines been deliverd, just need to go home sick from work to have a play
I LOVE YOU CLIVE (my dpd driver )
About to pull the trigger on one of the HIS ones, will they work fine with a real 290x in crossfire?
Is the non-290x bios just the standard 290 bios? I've been having some strange problems.
My i7-920 has been OC'd to 4ghz with zero issues for the last year. Now with this card in it fails to boot unless I put the CPU back to stock. Not sure what would cause this? I've also seen a few crashes in Windows - screen becomes striped/garbled and freezes then machine shuts down.
I initially thought the cause might be my 650W PSU but I've just upgraded to a Fractal R3 1000W Platinum PSU and the problem persists.
Thanks in advance for any help.
psu was my first thoughts, i think the non x bios is the 290 uber mode, it might be wirth switching it to see what happens
It may be that the 290 draws more power from your mobo's PCIE slot than your old card did. This could put the mobo's VRM's under more stress/heat, hence affecting CPU overclocks. Which mobo do you have? I have had similar issues with SLI/Crossfire setups whereby my max CPU overclocks drop (even on really expensive mobo's with good PSU's). Best thing to do is set CPU at stock and see how far you can clock the card. Once card clocking is complete, see how far you can get the CPU. Somewhere between highest CPU and highest GPU clocks there will be a nice balance.Is the non-290x bios just the standard 290 bios? I've been having some strange problems.

Jonny is your 290 overclocked?Unfortunately the problem remains.
If I turn off the PSU, hold the power in for 10 seconds to full discharge it, turn it back on I get a screen, set up my bios OC and boot happily into windows. If I restart my machine it boots fine. If I shutdown and then power on I get a black screen and the GPU fan revs up but never revs back down to the normal speed that it does when the machine posts successfully.
Very weird.
I've even reduced the voltage on my OC (after following a better guide to the one I've used before).
