are those idle temps ? pretty low.. im idling at 47 im from philippines. :woot:Quote:

LOL! I have 60°C IDLE!!!Quote:

Question:
Isnt vmodding a 7900GT a potential cause in killing it say at 1.4v and with a zalman vf900cu cooling it ? as some of my friends told me the voltage regulators on the 7900GT is totaly different from the GTX and thats one of the main reasons why 7900GT's die so often.
ive never vmodded it and its gone to :banana::banana::banana::banana:. a lot of people are having problems without ever tweaking the card from stock.
Lets clear up a few things. Those silver boxes with 1R0 etched on them are INDUCTORS. Inside they are just like open-air horizontal or vertical coil inductors, but sealed. Another common high power inductor design you probably see a lot on motherboards, is a torus (ring) with coils around it.Quote:

Also, I'm not sure what the deal with "mint-green" is? If you are concerned you should look up the exact model based on the markings, and make comparison based on that. I know some really good capacitors that come in mint-green packaging, and other in black or purple. It just depends on the make and model.
Yes, the PCB of 7900GTX is quite different. 1.4V is very high voltage for tiny 90nm lithography. Although adding a vf900cu provides better than stock cooling, similar to heatpipe GTX cooler, the GT still lacks the better and extra electrical components on the PCB.Quote:

Personally, based on voltage scaling results, I would advise not to exceed 1.4-1.45V range (which should get you up to nearly 700Mhz). Although you might get away with using stock cooler and some spare case fans in the long term, I highly recommend a vf900cu or better cooler for long term longevity (pay special attention in ensuring good contact and use high quality thermal compound). Also, its VERY important you provide adequate cooling of the voltage regulators and power circuitry on the back side of the card. Afterall, with increased voltage AND increased frequency, the poor card is burdened with handling a lot more power. Finally, although it seems obvious, make sure you got good high quality power supply with spare capacity. Although it might seem like you can get by, once overclocked and overvoltged, that GT could be drawing twice as much or more power.
PS: Since it uses 1.2V@90nm and just 256MB GDDR3, the 7900GT uses relatively little power compared to other high end card. EVGA and others, used the reference nVidia PCB design. Perhaps the design didn't have enough overhead room for OC and Superclock models. Initially, the manufaturers probably chose the cheapest components which met the minimum design requirements. This is evident by the minascule cooler. Although problems might not be apparent in an air-conditioned lab, a cramped case without airflow in a tropical climate can expose artifacts (insufficient margins).
60C idle is crazy. You're just asking for trouble.Quote:

hey guys i applied for rma and i got accepted by evga. Will they accept my card or charge me a hefty bill since i had to solder 1 cap back on?
And if so is there anyway 2 cancel my rma since the guy who sold it 2 me is willing to give me an exchange.

You can easily tell i solderd it on there's a pic of it like 1 page back on the thread.
well got myself an X1900XT for just 320€ ^^
to bad both my ramsticks are DOA -_-
i've already seen your posts about your rigQuote:

i recommended you to do the 1.45v mod (with condutive ink). the temps don't raise much and you have more "room" to overclock and play with benchs

i think this mod to 24/7 use its ok, with air (vf900)
@Jonas
the GTX only uses 1.40 right ? anyway il try that when my conductive pain arrives, first time ive seen that 1.45 diagram i've only seen the 1.3,1.40 and 1.55
1.40v - 3dmodeQuote:

u should have already noticed that there are a mosfet or a few mosfets (a little ic) that is very hot on modded cards. try to cool it down. i've swiftech sinks on them and a fan blowing to the all card

I already have zalman memsinks placed on those area's b4 i started using the card.
So... the new MSI models also have the revised PCB... just like the Sparkle....

NX7900GT-VT2D256EZ
http://www.msi.com.tw/images/product...-VT2D256EZ.jpg
All with purple caps... so those caps are key..
Edit: Sparkle, Gainward, MSI, Inno3D en EVGA (via RMA) already ship these card or will ship them soon...
very good, now all we want now is someone with one of those cards to report.
K.I.T.T has an Inno3D with those new caps.... looks like he's good..
http://www.xtremesystems.org/forums/...&postcount=122
Hmm, i wonder if Inno3d will allow me to change my card for a new revision PCB even though it hasnt shown defects yet..
Wonder if Point of View (maybe unknown for most of you. Especially in america) have the new revision. Ordered one 1-2 weeks ago. I hope i get a card with the purple caps only. Anyone who know's?
all the POV 7900GT's we have in stock are with the mint caps :( but maybe the new ones are the revised...
When i bought mine here in Sweden they was "unavailable", but the same day they shipped it. Properly and hopfully they were waiting to get them in stock that day and with the new revision i suppose. Haven't picked it up at the postaloffice yet. Will do that later this week.Quote:
