Volt mod 7800gtx 512mb?

sablabra · 18 Jun 2006 at 13:33

Anyone done this? Or a link to a guide maybe? I just want to hear other peoples experiences, and I might do it myself if someone can convince me(if it's not too hard)

No one?

Google??

2nd and 5th one down look pretty good

Yeah, I've come across a few guides, but I like to have some first hand experience before I might try it

Any first hand experience is appreciated!

I'm currently at 610/1800, and would like to hit at least 650/1800, or maybe 650/1900

. Then I would beat a stock 7900gtx by far!

And picture from finished work would be great! Btw, I'm watercooling so max load is 45c, cooling obviously isn't a problem then

I would be interested in this too. I've seen a few guides for the 256mb version but little for the 512mb. Lemme know how it goes plz

I got it cheap so it would be great to beat the 7900gtx

. But I'm not sure whether I'm going to do it or not, but as said earlier, I need to see a few guys doing it first

. I mean, the forums are chuffed with people volt moding the 7900gts, but haven't seen the 7800gtx 512mb yet

Do you know if there are any bios mods/updates available for the 512mb?

Yeah, I've found a few bios mods where you're supposed to be able to increase volts, but it doesn't work(other than maybe a little fraction

). What may help you clock further though is loosening the memory timings

. Other than that, doing is physical mod is probably the only solution

No one here who have vmoded it? I've seen som guys over at xs though. But I've ordered all the things I need now, so hopefully I will get the parts before the weekend

Nice one, would love to see some pics of your work as well once you're done.

Yeah, I'll make sure to take pictures

. I can't wait to see how well it works(if I can pull it off), and how far I can overclock it.

Soldering involved?

Yup, I have to solder everything. Here's a pic of how it should look like(somewhat

)

With the variable resistors I can adjust the volts from not too much over stock, to way too much volts

. The molex is to make it easy to measure volts(both for core and memory)

I've gotten all the parts needed now, so I'll see if I can get started in not too long time. But I'm not doing it in this summer heat, it's 30c here now and even hotter inside
