Nope, everything running at stock. Just a random hardware malfunction. Happens to any electronics. Thank god I got eVGA. They are going to send out a new card first, then I send in the defective one back.

Errmm ? Am I missing something ? :fact: :DQuote:
eVGA 7900GT @800mhz 1.7vmod
hmm. did you vmod your card and start having problems then try backing it down to stock? If that's the case you ran your card too high and the failure is your own fault. 1.7v isn't something to run throug these babies for long unless you've got exceptional cooling. The review that got 800mhz at 1.7v only benched, and they had a massive heatsink and a big fan.
The 1.7 is on another card. What's wrong with running 1.7 24/7 with water cooling + ramsinks and case fan blowing on it? It shouldn't be that bad.
if you have water cooling then I don't see anything wrong. with what graham_h pointed out from your sig I thought you might have fried your card trying 1.7 on basic air cooling or something.
Sorry I should of mentioned I bought two of these 7900's.
1.7v on a 7900GT is borderline I'd say
The VRM setup can simply not handle all that current, measure the temp of the mosfets and activley cool them IMNSHO
Remember; the difference between the 7900GT and GTX is mostly the VRM layout and active cooling for the mosfets... And that is for 1.4v...
So as long as I don't go any further I should be perfectly fine?Quote:

You can't go any further than 1.7. Well, I suppose you could, but it would require extensive further modification.Quote:

the good one is now doing 620/2000 on 1.37v. the other card, ive redont the mod maby a few dozen times now and still havent got the voltage to increase. its realy starting to iritate me. is there any reason it wouldent take?
which mod are you doing? I would suggest the easy conductive tracer mods for 1.4 and 1.55 first since it's so easy to remove if needed.

i finaly go it to work after i went to town and back, it was just working, so i guess i wasnt leaving enough time for it to dry.
clocks now, run through 06, 611/1808mhz. 9015 marks.
What 3dmark score did you get @ 800mhz core? :slobber:Quote:

Would it be ok using the stock cooler ?
graham.....can you scroll up 1 post and look at it yourself? I just posted 1.55 and 1.4mods. Garret just quoted my post above yours too. C'mon now....:banana: :banana: :eek: :banana: :banana:
I got 9200 in 3dmark06.
must have been a blonde moment for him...Quote:

Nothing wrong with YOU running 1.7V 24/7.. its just that I wouldn't do it. Afterall, its only 90nm, 7900GT is 1.2V stock, and GTX's 1.4V is already pushing it. Besides, unless you are trying to sqeeze every single Mhz, after 1.4-1.5V there is very little gains on Mhz.Quote:

Strangers with honesty like this, make me grow a big rubbery one.
and that offically is the creepiest thing I have heard all week...Quote:

Ive already done the gpu mod to 1.4v, i was just wondering should i use a pencil on the resistor like vr-zone says or should I use the car defrost stuff on it, would a pencil be effective enough or would it be better to just use the conductive paint?
Athlon 3000+ Venice at 2.6Ghz at 1.5v
Asus A8N SLI
1GB PQI Turbo DDR566
EVGA 7900 GT CO Superclock at 650/825 at 1.4v
250GB 7200RPM Maxtor Diamondmax
ULTRA X-CONNECT 500W PSU
the problems are happening to nonoverclocked/modded 7900gt too so it isnt the vmod.
The point to using a pencil is to lower the resistance slightly. If you use conductive paint you will short it out completely, which would put way to much voltage through your ram.Quote:
