XFX 4870 512mb bios wanted

Hey,

I recently tried to flash my xfx 4870 512mb (HD-487A-YWFC) with the asus top bios. It didn't work and all I got was a black screen and no posting.

I used the proper DOS method with a usb stick and the flash appeared to go well. I know I should have taken a backup of the bios.

I have tried reflashing with various other bios's including Saphite, ati, asus, palit and powercolor.

I thought that my xfx was a reference design but am now thinking that maybe it isn't. I think the cooler is non reference but would that make a difference?

The best result I get is with the saphire bios which displays the power error message "you have not connected one of the power connectors (or something like that)". Power is 550w and was always fine before flash.

Also when I boot having the xfx as secondary display I can get a display in windows on the second monitor but windows is VERY unstable and may only stay up for seconds.

So if any one can help with a bios or advice I would be pretty grateful.

I have requested a bios from xfx support but they seem to be pretty slow and I am not sure they will give me one.

Thanks guys.

Hey 95viper.

I thought I probably should have put up more info than i did.

Anyway Specs are as follows:

ASUS M3N78-EM motherboard
AMD Athlon X2 7750 @ 3.1
4 x 1GB Crucial Ram
550W ATX PSU - Here is a link with PSU details - http://www.ebuyer.com/product/102994

I have 2 sata drives in a raid0 setup too, put still get power error message when these aren't plugged in.

The whole setup is only about 2 months old. The 4870 is run from 1 x 6 pin from the PSU and a 2 molex in to one 6pin.

I never had power problems before the flash, and that was when I had the raid drives, cd rom, 2 x case fans and satelite card all running too, so it seems unlikely (but possible) that it is the PSU.

Is it possible the xfx bios would have been required a less power??

Thanks.
