Stock is a 20mhz delta in 3D, so that's the most accurate ;)

some weird crap is happening here imo:

with the bios you gave me un moddified and clocks at 560 1650 i only score 14k in 3dmark03. removing the throttle clock from the bios and moving the 2d clock from 275mhz to 400mhz gave me 19k in 03. however when overclocking (580mhz 1650mhz) and running 03 the test will get about half way done and then the system will hard lock and the display will go blank. not seeing any artifacts at all though

currently testing 05.

I like 7900GT = 1.2V. Thinking of trying 1.3 or even 1.4V? You might think its only 0.1V, but power/heat increases exponentially with voltage.
1.3V = 17% more power/heat.
1.4V = 36% more power/heat.
not including extra heat/stress from power regulators.
In addition GTX (650) is about 40% higher than GT (450).

STOCK 7900GT HEATSINK = LIMIT OVERCLOCK

Simply amazing that just a few months ago, before 7800GTX 512MB, people were pushing hard just to get to 500Mhz, and beyond was no-mans-land except for those with cascade. All of a sudden, 650, even 700Mhz is just "stock". W O W

higher voltage, higher overclock, smaller lithography process (90nm) = higher heat density (perfect contact, and copper base essential).

Those heatpipes on the 7900GTX heatsink are not just decoration ;)

edit: check the power regulator IC chips on the PCB if they are getting too hot. After discharging static by touching metal case, touch and see if you can hold finger 10-15sec... if not, then too hot).
they are typically in black TSOP package (looks like mini memory chip)

i do have an nvsilencer 5 installed on the card though. 3dmark05 ran perfectly artifact free at 580mhz core 1800mhz ram. currently running 05 at 590mhz core 1800mhz ram

yeah i have a thread on the installation a few threads down. 3dmark05 ran fine at 600mhz core 1800mhz ram. scored just over 10,000. currently testing at 605mhz core 1800mhz ram.

edit: 3dmark05 artifacts a little at 605mhz core. 600mhz core, 1800mhz ram is artifact free. not bad for a 7900gt. thats like 150mhz overclock over a stock gt.

Maybe it's better to put an extra fan over it blowing on the PCB. Remember that the 7900GT uses a different PCB than the 7900GTX. That's the reason I gave this mod only a 25% chance of working as it would be really weird if Nvidia gave this PCB the abillity to supply this voltage.

I'm fairly sure this mod doesn't work though and the not editible difference was caused by a moronic programmer and is totally insignificant.

The difference between the 7900GT and 7900GTX voltage table were actually 2 things:

1.) The 7900GTX had a third entry that was disabled after it was set to 1.4v first, that's pretty odd I think (stupid programmers?).

2.) 7900GT has a "0" value and the 7900GTX a "1" value, which is a part of the voltage table or it has some other purpose. It is not far after the voltage entries, that for sure. It can't be canged with Nibitor so I'm not sure if this is the think that makes the difference, I edited this to the 7900GTX value in the 7900GT bios.

@Pandora's Box:

So did this bios actually improved your overclock and made your temps higher if you have to be honest?

Nice overclock for a $350 card, it's really awsome at any vcore ;)

i think im done playing around with the 7900gt. was fun seeing how far it can go at 1.4 volts but im not comfortable running it at 1.4 volts all the time. back to 1.2 volts for me.

So did this mod actually really up your temp? And did it increase your overclock at all? If you're not sure about 1.4v you could also try the 1.3v bios:

http://rapidshare.de/files/15329733/...delta.rom.html

That is ofcourse if this mod really works. I do not think so actually as you're card is already 560mhz at stock and 600mhz barely benchable would be a really small overclock for a 0.2v jump.

I saw you posted that 570mhz was your maximum overclock with the stock bios. But on what standard was that based? Benchable, artifact-free or 24/7 stable? And is it 600mhz now as you can run 3Dmark at that speed, or was 570mhz just your 24/7 overclock?

with the 1.4volt bios and card at 600mhz core, 1800mhz mem. max temp i got with rthdribl was 57C using the nv silencer 5.

600mhz core was not possible using the stock heatsink and stock volts. flashing to the 1.4 volt bios using the stock heatsink allowed me to run 3dmark03 using 600mhz core. it artifacted but it ran.

after installing an nv silencer 5 and using the 1.4 volt bios i could only reach 600mhz core before i saw artifacts in 3dmark03. i stopped at that point.

coolbits detected 570mhz core as my max overclock when i was using the stock heatsink. havent tried using coolbits with the nv silencer 5 installed and stock bios.

also when i flashed to the 1.4 volt bios with the stock heatsink and ran rthdribl my temps were in the high 70's.

The difference between "running with artifacts" and not running can be pretty small. So this isn't very conclusive.

Quote:

And how high were they with the stock bios? if you didn't test this, can you please test the temperature with the Silencer using the stock bios and the 1.4v at the same clock? This is the only thing that would be conclusive.

Testing the maximum overclock isn't really conclusive. The higher vcore can fluctuate as the the pcb is not designed to deal with this. This also means that 1.3v may increase your overclock compared to 1.4.

So I just ask you one thing: Does the temps increase with 1.4v or not? Please test with same clocks, same cooler in rthdribl.

I think a lot of members would really apriciate it if you run this little test ;)

It will say 1.3v 2D and 1.4v 3D, but that's just because I named those voltage levels to that. Nibitor only reads out what you call it ;)

So if you want to be 100% you have to perform the rthdribl test once again with both biosses at the same frequency and delta. And make sure that both tests are done with a closed case or both with an open case to eliminate that factor. And let it run for atleast 15 minutes. Or you can take a multimeter and messure the voltage at the point specified a vr-zone.com

If this mods actually works I will contact the author of Nibitor to implement this mod into the new version, make a thread about this, and post an article at the frontpage as I have this privilege now :toast:

So from what I gathered in this thread, for best performance its advised to use the NV Silencer 5 over the stock cooler and bump the volts to 1.4, right?

You can't bump the volts without a hard-mod, they've discovered. Shamino already has up a vmod guide at vr-zone for the new nvidia cards I think...

Well, Artic Cooling NV5 is definetly a good start. Copper P4 HS, or waterblock is surely better.
As for voltage, only confirmed method is voltmod, using pencil or solder variable resistor (prefered): http://www.vr-zone.com/?i=3330

if thats the max your 7900gt can do on water then nvidia is definately speed binning these chips considering my xfx 7900gt xxx edition comes at 560mhz stock.

majestik you have to force the bios flash:

nvflash -4 -5 -6 bios.rom

thats the command to force a bios flash.

I bet they are speed binned, I just have to play around with it tommarow.

x1800xl isn't even in the same performance range. Even if you manage to get good overclock you still get about X1800XT performance (ie, overclock wont change it to an x1900)

well, after the volt mod on the gpu my 1 of my evga 7900gt oc sc does 610 3dmark06 stable. the 2nd card hated the vm on the gpu, in fact, i removed it and it has issues now. funny thing is that either card will just shut down at 1.35v on the gpu and really won't complete a run at anything higher than about 1.26v. what gives here? same thing with the memory, its much better without the volt mod on memoery. has anyone overclocked a gt past around 600, and if so what voltages. i am rather puzzled at this point as these cards really don't seem to respond to voltage at all.

i should note that this is the hardware voltage mod i am tring

i didnt see yet , but for what i saw in the forum depends in how much OC you have in the core like:

if you have only like 520MHZ in core you can do 1800Mhz in memory but if you have 560/570mhz in the core you only get 1700mhz in memorys , this its what i think for what im reading in the forum , not sure cause i didnt try yet past the 1650Mhz in memory . Max OC in core its 570MHZ ( stokcooler)

if the early results are any indication, the gt appear to have no headroom at all on the gpus

It's just cuz they are starved for voltage, we will get this fixed soon :)

same kind of tradeoff as on 6800's and 7800's.. higher GPU ->more heat, and less stable power. Shoot for highest GPU clocks, since give more 3DMarks (1700 is plenty).

i should note that this is the hardware voltage mod i am tring

cronic, perhaps overcurrent protection. Or, cold solder. What type of solder did you use, and did you make sure to clean the surfaces with acid/flux?

EDIT: yeah, starved for voltage and need better cooling (dont forget voltage regulators!)

My core craps out at 572

I think it wants more voltage.

I could try to use powerstrip to see if I can get the core higher.

how high should the gpu voltage generally be able to go on the 7900gt? with water cooling maze 4

No headroom?... 450mhz is stock, so 110+ mhz on the core on stock cooling and stock volts is no headroom????

yeh they are great cards , 450Mhz stok cloks to 570mhz its realy good and i also agree that they only dont go further cause they want more voltage

granted from 450 its not bad, but i bought 550 cards and would have liked to have gotton a lot more than 615. oh well. i would still love to see more results from people who havce tried the vm.
03-14-2006, 12:07 PM

yeh but CO versions its not always = will get more OC than others .They come with higher cloks default than others versions but that dont means that will OC more

look at the example of XFX 7900GT XXX edition that come with more cloks than XFX 7900Gt Extreme Edition and get same OC , only diference is that comes with high cloks default .

i think + 120Mhz OC core with stokcooler and stok bios its good

The NVXP-3 will fit the 7900 GT and 7900 GTX out-of-the-box without any problems. My two 7900 GTX are already running with two NVXP-3. :)

Seems that EVGA and XFX Partialy clocked cards are the best price/performance ..

Have anyone tryed some stock clocked cards and see how they perform?

My XFX Extreme (560mhz) is in the mail already. Cant wait to see what it can do with stock heatsink.

If anybody here actually hit anywhere close to 650Mhz on 7900GT with stock HS, I would be really really shocked. (EDIT: and stock voltage ofcourse)

1. If nVidia could get G71 cores up to 650Mhz+ with just 1.2V, don't you think that's what they would set it to?
How many of you are running Athlon64@3Ghz wtih 1.4V.. how many with 1.2V? 0.2V is HUGE.

2. Thus, about 40% more power due to higher clocks and 40% more due to extra voltage (about double combined - I posted more accurate numbers somewhere) -> thats what the heatpipe cooler for GTX is for.

Congrats to the guy who got 615Mhz.. amazing clocks for so little voltage.. just need to wait for nBitor (or voltmod)

thats what i said , that +120Mhz in the core than the default cloks (450Mhz) its already very good for this cards with default voltage ;)

BTW: who get 615Mhz in 7900GT ??? and with stokcooler and stokvoltage??? didnt saw yet

I went from 500/1500 to 553/1590 as detected by coolbits. EVGA CO cost me $300 shipped to my door from zipzoomfly.com. I will mess around with it later. I am making great progress getting my 146 0604 cab2e epaw that I got earlier. So far I am up to 2.85ghz on stock volts.

in coolbites in Find optimal frekuncies i get 550/815 with stokcooler , and Max core that it past in coolbites its 570Mhz.

next week i will buy a waterblok to the card and see if can get more than 570Mhz

I got an MCW60 and copper ramsinks for mine. I just need some bios that will add voltage and definitely work.

I'm pretty much 100% convinced upping voltage through a biosmod is not possible :(

Will a regular small saw be fine for cutting the NV Silencer 5 to fit the 7900GT, or would you use something else?

Maybe you can heat up a sharp knife and slice trough it like butter.

The plastic needs to be a thermoplast (melts under heat, no chemical reaction). You can test this by put the flame of a lighter for a sec on the piece you will cut of anyway. If it turns black within a few seconds it's not a thermoplast. If it melts then you can try my idea. Do this in a sink as the plastic could catch flame.

I post this because i have modded an NV5 once and I noticed it is really tuff plastic. Didn't try the hot knife method though, it's just a suggestion. Else you could try a normal small saw, like a saw for iron or something.

Ok here are my latest results with my EVGA 7900GT SC OC (STOCK 550 / 1580)
This is stock voltage ( 2.03v mem) and a hardware mod with a 50K ohm trimmer for the gpu

Thanks here is a pic of one of the cards. I wish I could send more volts to them, but they won't take it at this point.

Thanks for the pic!

Did some nice work there :)

prolly gonna need some pretty cold water to get them to like more volts and go higher. Keep up the good work, your flying through a fast pace haha.

higher than 1.275v 3d for gpu? that doesn't seem like much of an increase at all. they load temp in these runs were 24-28 c for both cards, which is fairly low. why can' th these cards take 1.400 gpu voltage or at least 1.300?
03-14-2006, 10:32 PM

oh wow I read that totally wrong. :-S Thought the volts were high lol. Odd that they are not responding at all to the higher volts. Perhaps there is some sort of OVP???

evga 7900gt superclocks
550/1580 stock
bench run at 550/1800
cards game at 580/1820 with stock cooling.

cant publish 7900 scores in the orb yet, hence no link. but only 6 or 7 scores higherthatn mine @ 2850mhz, half were x1900xtx crossfire the other half 7800gtx 512 sli. highest score was around 9600. my score with 7800gt sli was 7200, so i got an 1800 point increase for a 25% performance bump, well worth the $160 the 2 cards cost after selling the 2 7800gt's. i had.
