Last upgrade: overclocking Radeon9800Pro:
I succeed to overclock GPU from initial 338 MHz memory a 378 MHz GPU core:

to 351 MHz memory, 392 MHz GPU core.

I also equip the card with new cooler - Thermalright V-1 Ultra, slightly modified to don't block nearby PCI slot.

even if overclockig is only by 2-3%, SDLbench faster by another 8%.

Nice! Just now, my Pegasos have overall score 3341.66 in http://hdrlab.org.nz/benchmark/gfxbench ... esult/2155
It is faster than some SAM460Ex with HD cards, even if this card have no compositing under AmigaOS.

Best 2Gb memory configuration:

I checked many ram company for add 2gb full system bosted on pegasos but the best result i had with

Serials of the rambank:
Crucial: PC3200U - 30331Z 1GB DDR 400 CL3 not ECC unbuffered (perfect woking with 2x modules)
Buffalo: PC3200U -30330-B1 1GB DDR 4000 CL3 Not ECC unbuffered (working great in second slot in couple with kingstone 3200 1GBDDR 400)
Kingstone: sorry i dont have the stick on it for know the serial
Since those Crucials seem to be hard to get, what about those: 1GB Crucial CT12864Z40B.E16TY PC3200U 400MHz DDR1 Non - ECC? Would they maybe also work?
