I don't really count myself as an extreme modder, some of the things that people get up to in forums such as this, are way too extreme to be considered sane.
But anyways, been trying to overclock my 5900XT, had'nt had as much luck as I'd hoped, compared to some of the mad overclocks I've seen people get on their 5900XT's.
my 128mb Galaxy zeus XT has default clocks of 400/700, so far with the default HSF, I've reached 450/820, but trying to push it beyond that created severe artifacts in 3dmark2k1, So of course I wanted more but the original HSF was'nt upto it, so heres the pics of the mod.

Its an old Athlon XP heatsink with a silent coolermaster fan,
Lapped to a mirror finish using wet n' dry from 600-3000 grade.
then finished with a polish of "brasso" (an abrasive brass, copper polish).
I then used surgical spirit to clean it completely.
My new overclocks are 480/860, I know the memory will go higher, But I'm still testing.
Its throttling back, and using a bios editor, I've found that it throttles the memory at 750 or higher.
Tried a bios from a Leadtek 5900 Ultra, but it did'nt like it.
So next I'm gonna try a bios editor, edit the original bios and set the default clocks to 450/850 and load that in.
Been way to busy to try it yet, house is turned upside down for decorating etc, so it'll have to wait to wednesday next week or so.
But if the new bios works, it'll be interesting to see what I get.
By the way, the heatsink is secured with 4 self tapping screws and plastic insulating washers (under the heads), the screws go though the 4 holes that surround the gpu, and I know the heatsink looks big and heavy but its lighter than it looks.
If anyone has a 128mb Galaxy Zeus 5900 Ultra, I'd be very interested in having a copy of its bios.
