For INFINEON 3.3ns mem. 9500 nP !!!

First, my English is bad, sorry.

Second, any of you, is try this ?:

VDD and VDDQ - must be EQUAL (as possible) !!!

For default 3.3ns (300MHz) = 2.5V (VDD=2.5V / VDDQ=2.5V)
For default 2.8ns (350MHz) = 2.9V (VDD=2.9V / VDDQ=2.9V)

With 3.3ns if you wish to reach ~340(or 350)MHz, try set
2.9V to 3.0V (max. 3.05V or if you are "little crazy" 3.3V :)

VREF must be VDDQ*0.5 !! (min.*0.49 / max.*0.51)
--------------------------------------------------------

EXAMPLE:

VDD = 2.95V
VDDQ = 2.95V
VREF = 1.45V (2.95*0.49=1.445)

Than you maybe able to reach ~340MHz !!!


What you thinking ?!

p.s.
Try Samsung 9700Pro BIOS and MUST COOLed alumunum plate
on back of card (with Fan from Pent.1 or with HeatSink)

Hi!
I'have a 9500NP with infineon 3.3.
with overvolt 2.85@3.3v I can reach only 320 without ramsinks :(

infineon 3.3 goes worse than some hynix 3.6 :(

Hello,

I now that, I read your thread "radeon 9500/9700 "new" pcb 3.0 vmem mod partially discovered!". Good thread, thanks.

"Yes, I have 2.87@3.3, 1.25 for vref, and 2.5 isn't modded"

This is wrong proportion for VDD/VDDQ/VREF.

Did you try my propose for that ?
(Hynix and Samsung work on that base)

Sorry for my limited Engl. (bad in writing).

ok for proportions, but the overvolt is only 15%
