plz stop im blushing :P

I just took apart my card and replaced my thermal paste, gonna wait untill I have a little more confidence to lapp it, but man, you would have been amazed at the crappy job they did on applying the old stuff! So far, after replacing the paste I've gotten down to 39'C idle, and after a half hour atitool stress test its maxxed at 64', a lot better than before, at my current oc its gotten to 80' max. I'm still not doing as good performance wise though, I think its got something to do with my new bios, but not sure......

Lap the heat sink!! Shiny=Better!!

Anybody knows how to apply an vmod to a Gigabyte's PCB, it's different from the ones I show here. I watch a guide in portuguese in the URL: http://www.techzonept.com/showthread.php?t=166236 but I can't understand Portuguese.

Hi. I was just wondering, if I will raise voltage on a new VGA BIOS settings, will I be able to OC my 85GT more? My current mobo doesn't support any options to change any voltages. I managed to push 85GT to these clocks http://www.techpowerup.com/gpuz/gfvzq/ through ATITool (~5h stress), but I think it's possible even more. And what about pencil mods? I really can't get them, sorry. You just pencil the necessary contacts and what's it?
Thanks

Pencil mods just lay down a layer of conductive material that bypass certain resisters. Thus a small volt increase. Check out the layout of your card and see if it matches the layouts from the first page. If not just google the specs on your cards and you'll prob find the places to pencil in.

btw welcome to TPU!

[pyracy]

have you had a chance to check out my bios and see whats wrong? my performance is lagging a bit and cant figure out why!

[Solaris17]

give this a try bud

[pyracy]

will do, thanks alot, ill let ya know how it goes!

Actually its exactly the same as the inno3d the chips are just rotated or exactly like the palit version(also rotated)...but because you asked so nice

Hey Sol, had a go at the vmod. I can hit 875.1912/880 with the pencil mod. Tried the vr mod but it didn't work out. I realized after I took it off what I did wrong. Case ground only works if it's in a case
Is there any reason I can't use the fan ground pin on the card?

i dont see why not go for it. i was just throwing up some quick pointers congrats in the vmod excellent work the 8600GT may be out of date and upon its release it was considered "mid end" gaming but imho it is NO babay and holds its own even today...with the proper bios and volt modifications you can make that thing pull some serious tricks out of its hat imo by far the BEST and funnest nvidia card to date to mod.

[Skitzo]

mine will prolly only get used for folding so I'm gonna see what I can get out of it. With the pencil mod I managed ~2300 ppd. Curious if I can hit ~2500 stock was ~1400

[Solaris17]

well my philosaphy and if you saw my various 8600GT projects you know what i always did with it PUSHSHSHSHS i didnt have resistors at the time but i had so many plans for my 8600 ill probably buy another some day....i wanted to push that thing past silicon limits i wanted it shaking while it was running. i wanted to sweat and jitter while it was TRYING to complete a 3dmark...im sick like that...but me and electronics have an intresting relationship..i just have to find out "how much?"

[Skitzo]

yeah, it's not working.
I'm sitting here wondering, I don't recall seeing a pic of my card xfx 8600gt xxx with the solder points marked. I picked the chip beside the pencil mod resistor for the vmod. Is that right, or did i vmod my gmem?

can you give an example? XFX 8600 pcbs are the only ones im not sure of their seems to be about 40 diff layouts so i dont claim to be able to help anyone with a pcb design on the front page.

[Skitzo]

give me a sec, I'll try to take a pic....

[Solaris17]

well ill come back tomarrow and see skitzo its ~5pm my time and i need to work till 3am so i wont be back on till round 10am my time tomarrow.....and then i need to do it again.

[Skitzo]

kkk when ya get a chance ...


sorry about pic quality, best i can do...

[Scrizz]

Excellent choice in cooling there. That Thermalright V2 is great.
My 8600gt never went higher than 53Cat max oc of 930/1966/1000

[Skitzo]

yeah, it cools the core quite well. I'm hitting 53*C @ 875/1912/880 and a Hyper 15mmx80mmx80mm fan. I can't help but think the heat pipes mess with the cooling on two gmem chips; I see that affecting gmem oc. I have to cut up some mosfet heatsinks to hit tight spots, it can't hurt

Scrizz, did you do a solder v-mod, if so do you have a pick?

[lycanwrath]

Thanks for the help Solaris

Will try these volt mod and post back soon

[lycanwrath]

Thanks for the help Solaris, but sorry to bother you again.

I don't think that my card has merely rotated chips
Apart from the big the Chips , the tiny ones also are not ordered as those on my card.
I have taken a closeup pic of my card (see below, the best I could)

Can you please show me where i need to shade n check for voltage on this pic.
Thx in advance.
