Guys used my new 5870 last night with no issues.
Came down this morning to continue testing and benching it boot to windows and bang my desktop has green pixels flashing all over it goes black on and off every few seconds!

Does anyone have any ideas? I've tried speaking to xfx but they're being really quite slow!

I havent even had the chance to use it properly and certainly havent tried oc-ing it yet so its not that!

Cheers in advance

What PSU you got on it? All sparkly sounds like a memory problem which may be caused by lack of power :P

I have a corsair hx750 so I'm guessing thats enough

You can see the rest of my specs in my sig I'd have thought a decent 750 could cover it, cant it?

Right.. now you need to trace to see which rails that GPU is sucking. Report back when done.

disconnect your four hard drives that are no boot drives and pop back to one stick of ram, that'll give your PSU a little more juice to feed the GFX. Take the CPU back down to stock speeds as well. Basically, this'll give the PSU more headroom and you can see if the PSU is the cause with a pull of a few plugs.

What did you use to verify your clock on the CPU?

Clock the memory down.
If it resolves the issue, it's faulty memory.
Do the above first however.

The HX750 only has one 12v rail

The Cpu is stable in ibt and 12hours of prime 95 and has been running stable for weeks so thats not the issue. I will unplug the hard drives and ram now and report back to you. I doubt it is the power supply though because I had it playing crysis in 1080p and teamfortress 2 with everything on highest yesterday without any issues.

But i'll give it a punt
cheers guys

I think, rumour has it anyway, that the world ended briefly this morning but it seems to be getting back to normal now.

So many people overlook, or ignore the importance of a GOOD PSU :rolleyes:

I had a Corsair 620 fail on me last year for no apparent reason, dropped the 5v rail i think... either way it went back and i bought a PC Power&Cooling TurboCool, havent looked back since, little noisier from the fan, but as solid as a rock.
