MSI 7900GTO Vmem mod

[thehellrazor]

My 7900GTO overclock well enough. 720MHz (+50MHz delta) on air.

If you pencil that right 1.2K ohm resistor--> voltage will raise. Lower resistance=higher output voltage.

If you want you can try this mod:
Attachment 52295

Connect those two points (red line) with silver paint or something similar. Connection must be complete (0 ohm).

You will get ~1.45V in 3D mode. That's 0.05V over default. It might help.

Somebody tryed this ??
I get 750 stable on the core on stock volt and cooling so would be funny to see how far the core will go with a little extra voltage

Wonder if MSI did a half assed job replacing those resistors on my card or sth as it was whining since start in some games, most likely was a bad cap somewhere tho. Really hope they'll send a new card, wonder how it clocks, this one clocked very good on mem, up to 850 on stock volts but core only went stable up to 690 or so.

wow... 750 is quite high, incredible
It should fly with 1.5v or something like that... I haven't tried higher than 715 yet... may look into that this week

nice mod
i may want to get a 7900gto now... too bad us usa folks cant get msi ones, only evga
for all the people that say their card overheats (thinking this is like most other vid cards) and cant overclock that high, ur wrong
u run into voltage problems waaay before u run into temp problems
just wanted to make something clear to some guys that say their card always overheats

Has this VGPU mod been tested / confirmed?

Thanks!

IT GETS TO HOT. PERIOD.

They can even look into the log file, Rigth click this computer- manage- Event log.

You fill find a message in there.
I will have to flash the bios when I geet home to increase Fan speed and then do the Vcore mod

BIOS said my already goes to 100%.
Has the VGPU-Mod tested?
Try to polish the cooler with nevrdull.
It gets my card @ load 7°C lower!

Yes. Try it! It helps!

EDIT: Silver-Paint is drying!!!
I must wait ~1 hour.
Please wish me good luck.
My multimeter shows me an resistance of 5ohm.
Is that bad?

don't complain about USA can't get MSI ones. We can get it in the UK but they are 30% more expensive like any computer component here in Europe. I wish we have pc parts as cheap as USA!!!! I am after an opteron 170 in the UK and they cost over 400 dollars here

BTW my MSI cost me about $306 (£170) + delivery, you can get evga in the USA for about $250
