V-Modded 9800PRO ? max Volts?

[TiTaNiUm]

I just completed 3rd of 4...I did the V-core
V-ref and V-ddr...All are on Potentiometers, I was wondering what Voltage people are running the mods at,
AND do i need to do the V-ddq before i should expect performance gains??

My system:
AMD XP2500 ran as XP2800
Leadtek K7ncr18D-PRO
2@256 Corsair xms pc3200
2 Maxtor 80gig w/8mb,cache Raid-0
RocketRaid 133
ATI 9800-pro
450watt Dedicated power

My first 9800 pro was voltmodded out of the box..(The DDR and GRU modding).It was an erly produktion in erly marts.

the GRU is Prometeiacooled, and goes max 520
510 solid. The volt is 1.85 (1.80-1.87)

Thied different voltsettings from 1.79-2.00 but alwais the bench freese in Nature about 524.

The Memvolt is 3.5volt. Tried 3.4-3.7, get hot and artifacht beon 410.


Just got my 2. radeon 9800 (Herkulers) Removed the silly fan, and voltmod and Prommy:

Doing 555 at least on 1.80-1.85 volt. -

The memory is funny. perfeckt at 405 at 3.5-3.6 volt. Over 410 it is no good. IT help to ajust the volt to 3.9Volt?? how mutch can it take?
its 2.2 ns ?

:rolleyes:

Some more testing have to be done. I think I'm getting close, The prommy R404 IC7 G rig can bench 2001 and 2003 at 4207mhz stabil.
:D :p
Have to hurry my 3200@4500 comming soon.

That Hercules chip is the same number as my ATI 9800pro chip and the same chip that is on the ATI 9700pro.:p
