Nice.
=)

But why four resistors?
And I take the card has Qimonda GDDR3?

[rDLx]

2 trimmers are for the OCP mod, i get the info from techpower up's guide
and yep, the mems are qimonda = sux

anyway, i´m not sure about how to do the ovp mod... it wasn't clear from what i've read around

[largon]

What resistance did you set those OCP VRs?
Btw, I don't think you'll need OVP. It seems these cards have a high voltage tolerance - I've benched at 1.65v without problems.

Damn so in my mods i didn't see your mate :up: Te quedo muy bueno yo soy de Montevideo Uruguay :D

very nice work !!

Cheers mate

[s0lid]

Damn it dude :D
Using those connectors is an damn good idea! :up:

[rDLx]

thanks friends!

largon: trimmer fits it in 4.2k, which i help myself to pass 830mhz
of core, but i cant pass the 880mhz though adjust vgpu on 1,6v...
my challenge is to pass the 17k in 3dmk06

regards! Salu2!

[dengyong]

Nice results. I wouldn't have used the hot glue though, there's more chance of pulling a resistor off if you bump it against something.

very nice score :)
hey dude , is that voltage safe to be used for 24/7 on f@h ?
I cant push more to my 88gt unless vmod it :D

[rDLx]

thx dude

This voltage is safe. For the present it gave to me problems neither with the stability nor with the temperature.

If i was increasing a bit the frequency of the Q6600, maybe pass 17k points

pd:my english u sux :(

[philbrown23]

wow! nice mod! nice webpage too! to bad I dont speak spanish :(

[PPInDaHouse]

Also did the vgpu and vmem reverse mod some days ago, not as perfect as yours, but working :D

I used a 100k VR tuned for 50K for the vmem reverse mod
