Independently OC them? I'd think only via a BIOS tweaking utility.

When you overckock GPU shaders go Automatic,editing bios Do Not change anything ,i lowered shaders by editing bios and i set GPU at 890 shaders 1890 like before and 3dm06 score was lower then before 6345 vs 6577.
The best settings I have gpu@865 shaders 1890.
Shaders DO NOT overclock more then 1890 with Vcore 1.6V

Wow :slobber: The card outperforms my OCd 7800GT.

great stuff!

That is 7900GTX performance with DX10, AA+HDR capability and better AF right there, very neat. Though how is the temp with that overclocks ? can be VF900CU do the same job ?

the temp are idle 52C burn mode 67 clock set at only 3D mode,
new score next 300

in Xpand Rally Xtreme you can see MOD performance vs stock overclocking,shaders moved 10mhz than stock.
I`ll have second card next monday,next mod ,next tests but SLI performance.

Do you think it's possible to add a psu mod but instead of wires could I just detach a old psu hookup off a burnt card I have . Here are the pics of the psu connector I could detach , it looks pretty easy but I'm not sure how it would fit. BTW the card is a fx3500 that was dropped and never worked if anyone knows what could be salvaged let me know .

Ehr?! I allmost wasted my coffe here, so in high-res with some heavy eye candy, th 8600GT /moddet and OC, performes as a 7900GS 630/850 and allmost as a 7900GTX?

Or did i get it all wrong?

I'm thrilled to report that Chri5g's results are no fluke. :up:

I've got the same card, and I am seeing similar results with my voltage modified, Zalman cooler equipped card. I'm running vcore = 1.70V, vmem = 2.25V. Fully loaded, my temp is a pretty stable 56-57C.

My mem wouldn't clock as high, but my core went even higher:
http://www.parisgroup.net/images/rivendell/atitool.jpg

That's a 66% oc on the core!

My resulting 3dMarks06 score:
http://www.parisgroup.net/images/rivendell/3dmarks.jpg

For those interested in doing this mod; I followed this guide on VR-Zone: http://www.vr-zone.com/index.php?i=4925&s=4. The Inno3D card is laid out just like the eVga card. I attached two 25Kohm variable resistors and 3 voltage reading posts to the card. Here's what the mod looks like:
http://www.parisgroup.net/images/rivendell/gpu1.jpg
http://www.parisgroup.net/images/rivendell/gpu2.jpg
http://www.parisgroup.net/images/rivendell/gpu3.jpg

As it turns out, the ground post isn't really necessary. I just make the ground connection to my case when taking readings.

Very nice results !!!! 8600 G84 core FTW

Makes me regret buying a 8800GTS 320mb as my entry card as I really only play CS:S and Warcraft III.

Damnit

damn my 7900 gto gets 7300 on 3dmark06 and my other specs on my rig are higher but then again I've had this card for awhile.

From those game tests, it looks like it takes the 8600GT approx. 50% higher gpu clock rates,...and faster mem ( as compared to 7900gs) to get roughly the same performance. Probably no one getting much past 750Mhz or so with a 7900 on air so I suppose that would have to be taken into consideration in a comparison.

Any real gaming results? I want to see the increase :)

10-20% increase and no increase at all on 7-series?
Even though I like the 8600gt, I don't think those drivers will be enough of a difference. Besides, isn't there supposed to be some sort of problem with those drivers?

I have PNY 7600GT and i did NOT see increase at 162.15.They are for 8 series.
WHQL we will see today or tomorrow

Interesting.....
Maybe I'll pick up an 8600 and run some tests vs a 7600gt.....just for my own fun. :D Of course, if I were to use 162.15 drivers AND if they are optimized for the 8 series like you say then to be fair I would have to use the drivers that are best optmized for 7 series on the 7600. My 7600 has a 80nm gpu so it should be interesting to see how the clock speeds scale at any given Vcore.
Still, my comments from two posts ago (my posts) are valid. You will need approx. +50% core Mhz versus 7900gs to equal it. Will the new drivers reduce that number? .....let us know.

Amazing results, but... :up:

DID ANYONE TRY THIS IN SLi :shocked:


will 2x 256MB video card ram in SLi be addressed as 512MB in game performance?

what about the 8600gts? 8500gt?


this is best mod since x800GTO to X800XT !

I just chose this card over the 8800gts 320 b/c I saw your thread the performance your getting and its only 99.99 with rebate, so it saved me 160 bucks.

I plan to OC this as high as possible. I run on 2x22" screens and plan on running an hdtv after black friday. Ill get another card if I need too after that though.
I dont really play many games, mabye a little CnC3 and just do mostly webdesign and file conversions.

Did you upgrade your stock cooler at all chris? if so what kind of cooling?

By pencil, do they just pretty much mean draw over the resistor with a normal wood pencil to make a small conductive layer?



What kind of max temps should I be aware of?

hmmm i'm gonna try out some these mods myself on my buddy's card :D

I had one for a week scored some WRs with it im running a 8800 now and trust me it is faster . http://www.hwbot.org/searchMembers.d...CConsole%7C%7C

There were my scores

Well I just got my whole system built and running.

I can get my 8600 to 650 core and 850 mem with stock cooling and voltages, I just changed out the heat pads to AS ceramique. What prog to you use to change voltages? My temps are in the 70's and I think thats alright for these cards iirc.
