4870 ASUS TOP BIOS (upto 900MHz in CCC)

[Paulo Jorge]

Is there any bios for the 4870's with 1 gb ram?

Here's one at techpowerup : http://www.techpowerup.com/vgabios/2...24.080819.html

Core: 800Mhz
Memory: 925Mhz

Don't know if it's the default or not

Nope, those are not reference clocks. I advise everyone to be careful about flashing your cards with a 4870 1Gb BIOS with DDR5 frequency above stock. 1GB 4870's use double density DDR5 chips and they are more sensitive to higher frequencies.

My Sapphire 4870 1Gb can't take anything above 920Mhz (3680Mhz effective, even with the fan on full 100% duty) without getting massive artifacts all over the screen. I've seen people taking 4870 512Mb cards as high as 4000Mhz, and while they're being successful with those chips, somehow I don't think the 1Gb versions will go that high without dying or without a voltmod...

I'd be very careful with that.

So is the only 1gb BIOS anyone has found or tested yet? I just got an ASUS 1gb 4870 and want to try this BIOS flashing but want to make sure I am using one that someone has used and succeeded with.
