Possible 6870 Problem?

Hi

I recently purchased an 'XFX 7870 GHz edition' graphics card that I'm having an awful amount of trouble with! But before I list the problems I'm facing with this card I'd like to know if it's possible to damage it by hooking up a PSU that's too powerful for it? I'm asking because the instructions supplied were a little vague and never stated whether I needed to connect the PSU's two 6 pin PCIe connectors or just the one, so I connected the both of them (attempting to run singular and not crossfire mode) but fear I might have been wrong? My PSU is an HP-580AP which is a supported PSU as stated on AMD's website!

Thank you for any advice offered
 
Wow, thanks for the rapid response. I'm using XP SP3 32bit edition with 4Gb of DDR3 ram and a P5E3 Deluxe and the framerate is terrible, my GTX260 which the 7870 has replaced easily outclasses it, Deus Ex Humam Revolution is so choppy its unplayable. I've installed several driver versions but the results are the same, also if the 7870 is inserted into the primary PCIe16x1 slot the PC won't display anything on the monitor but will if I connect it into the secondary slot? If I insert my GTX260 back into the primary slot it displays properly every single time?
 
I only have DVI connections on my monitor but I'll attempt to connect it to to the television set then as it has HDMI connections. I'm currently using the 12-8 XP 32Bit drivers and when I look at graphics section of CPU-Z all the info is blank except for the card type which says 7800 series, I tried it yesterday using a different driver set and it displayed the clock speed as 300MHz?
 
I'm checking the manual to see where that would be in the BIOS, but if the BIOS was incorrectly setup surely my GTX 260 would fail to boot too?
 
I'll happily flash the BIOS but didn't think I needed to as the monitor displays properly with the 7870 inserted into the secondary PCIe16 slot. I just hooked it up to the TV through the HDMI but the same result, it displays fine if inserted into the secondary PCIe16 slot (albeit with lacklustre performance) and fails to display at all if the card's inserted into the primary slot. Still boots into windows fine though but the monitor outputs a black display?

That's what I mean, both PCIe16 slots are full speed as its a x38 motherboard, but I'll follow your advice and update to the latest BIOS and see if it helps at all. Do you think I'll see a speed improvement if I drop back down to 2Gb of ram as I'm running XP 32Bit?
 
Ok BIOS updated to the latest version but the issue remains the same! I don't know what else to do? I've reverted to using my trusty GTX 260 again which is working flawlessly and runs rings around the damned 7870, why I went from Nvidia to AMD I'll never know, but lesson learnt I suppose!

Thank you for your help Wazza
 
That's the thing, on paper it completely decimates my current Nvidia GPU, I can understand the possibility of bottle-necking due to an older OS, but no details showing up in CPU-Z under the graphics tab apart from the card family name and it refusing point blank to work properly in the primary PCIe graphics slot are simply unforgivable in my opinion!
 
Do any guru's out there have any idea why CPU-Z doesn't state anything in the graphics tab apart from the GPU name, all the info under Clocks and Memory is completely blank?

Mine is same for my 7950 on Win 7.. dont bother with cpu-z for graphics and search for gpu-z for ur graphics info.

Edit.. u probly need a bios update on ur mobo for that card to fully work and tbh u need to upgrade ur OS.. XP is ooooold man :)

I'm about to install Windows 7 64bit Professional Edition now, I flashed my motherboard BIOS to the latest version yesterday and I'll go ahead and check out GPU-Z after I've finished installing Windows 7.

Thanks
 
Quick update to any 7870 owners who stumble onto this thread. I went ahead and installed Windows 7 64Bit Professional and added another 4Gb of previously redundant DDR3 RAM, fired up Deus Ex again and the frame rate and gameplay were superb with zero choppiness. So, as a few of the posters above who had suggested most of my problems were likely down to using an old, 32Bit OS appear to be correct and that upgrading the OS would resolve my issues. However the card 'still' won't display an image on the monitor when inserted into the primary PCIe16 slot despite the fact that my GTX 260 'will', but at least it's working beautifully the secondary PCIe slot (which is a full speed slot BTW, X38) so why bother worrying about it right? When I reviewed the card via GPU-Z as recommended by a poster on this thread it displayed all the 7870's specifications properly!
 
Is that even possible, I mean the 6870 not working properly in the primary PCIe slot but working fine in the secondary one, even though my GTX 260 works properly in the primary slot (I know it's an older GPU)? As stated above, I also flashed my motherboard BIOS to the latest version! I know it seems as if I'm repeating myself, but I'm just trying to expand my knowledge base.....
