ATI 4870 problems...

Well, i recently upgraded my 9600gt to a sapphire 4870. Everything was great, that is, except for the idle temps. So i did a google search and followed the instructions ( http://www.hardforum.com/showthread.php?t=1320090 ) to try to decrease my temperatures. Everything worked fine, i saved the bios to the graphics card, and then i restarted. I played some crysis, no problem again. Then i turned off my computer for a couple of hours, and when i came back and tried to turn on my computer, nothing. It turns on, EVERYTHING powers up as it should, except my USB keyboard (which always should power up, even with a graphics card problem) doesn't light up or work at all as it should, and my screen remains black. My thought were that i messed up the card, but how would that effect my USB keyboard from not lighting up.

System specs:
ABS 700w tagan
AMD Phenom 9850
MSI k9a2 platinum
2x1 gig mushkin 1066 ram
Saitek 2 tone keyboard with gaming pad (which i have never used and haven't installed the drivers for)
LG 22"

P.S. Help...

If you would of read the last post on that site it states this:

I probably wouldn't try changing clocks yet. Wait for an official BIOS release (they have em for 4850s already) before flashing to a new one. There are supposedly issues with changing frequencies on the BIOS with 4870s right now (since the RBE only states support for 4850 right now).

I don't know if that caused your 4870 to not work?

Or go into your bios and make sure everything is causer. Make sure everything is plug in right, post back soon.

hope that helped good luck.

If you would of read the last post on that site it states this:

I didn't change any of the clock settings, just the fan. I did plug in my old card and it said this. "Warning !!! The previous performance of overclocking is failed, and the system is restored to the defaults setting"

I've had this problem before when i put in some weird ram, and i then put in my older ram and it fixed it (it turned out to be i didn't increase the voltage to 2.1v...). I'll try to increase the voltage on the ram and put in the 4870 again.

Thanks for the help everyone... I've determined that i jacked up my card... Now lets all sit around the camp fire and laugh about my stupidity! . Uh, i also have a question. Is it possible for me to plug my 4870 into another pci-e slot on my motherboard and flash it to the old version, or will i just have to RMA it?

Thanks for the help again

This is correct, you can put it in another pci-e slot and re-flash it. to the old one, but if your card doesn't work, then RMA it immediately

Good luck man

you shouldn't touch that card yet.. wait for stable drivers, bios.. all those drivers just came out after beta.. dang..
i don'tknow what to say.. try to put your card in other pc..

you should install at least some usb drivers

Why don't you try using atiflash. You can get it from here http://www.techpowerup.com/downloa [...] _3.59.html . I used it to flash a couple 2900pros to xt and some other stuff and it worked great. You have to use it in DOS so here is a good bootable flash drive progam http://www.bootdisk.com/pendrive.htm . Just create the bootable usb stick and put atifllash on it with the original bios in the same directory. Once you boot into the USB stick you should be able to follow the help instructions by just typing atiflash in the command line. Let me know if this helps.

Thank you!
This thing worked, just create a bootable disk (i used a floppy..) from here http://www.bootdisk.com/ and then just follow the instructions from the link that morerevs provided. Thanks to all that helped, and hope this helps the people that noobed it up (like me ).

WinFlash is what's bricking the 4870's as it only flashes 64kb BIOS files. The 4870's are 128kb due to the GDDR5 RAM. Use ATIFlash and you're good to go. I modded my 4870 BIOS fan serttings with no prob using ATIFlash 3.60.
