A Big Thanks to Mickey Mouse for VModding My 7800GTXs!!
:banana: :banana: :toast: :toast:
Did vcore and vmem mod.
But i get no volt to mem when booting =(
Vcore reads 1.285 and vmem ~0.
Get no picture on screen but computer boots up.
Tripplechecked VR and they are fine at 100.4K for mem and ~197ohm for Vcore.
Cut the cables for mods and still mem reads 0.
Ahw sorry Jason. Didn't know you and MM were one in the same. Never did get the Vmods you were going to send or sent. Wrote you a couple of times but got no reply after our first few emails. I may have blocked your email domain by mistake lol.Quote:

I have never taken credit for the original mods. Near as I can tell they came out of nVidia R&D proper when they were trying to bust some records since there was an NDA on them for a while.

As Jason pointed out they both do the same thing. I just picked up alternate solder points that were easier for most people to use. Not to many people can solder to the end of a 401 size SMR to start without killing it and if they do it is fairly easy to rip the end of it off with a slight tug on the lead. I always pick up the ground plane close to the mod point to keep noise down in the regulator feedback circuit.Quote:

I found most NV47 cores do not respond with any meaningful increased OC above that point ( yes there are of course exceptions ). There seems to be some rather shakey evidence the cores may flat out not like Vcore above that point as far as life is concerned (like the NV40's) but it is very hard to separate the wheat from the chaff in the forums.Quote:

Ok thanks ViperJohn! Thats good to know.. Well i've done one of the 2 cards now. Now to get the second done before my wife gets home from work with the baby.
:)
Thanks for all the help and thanks for making this thread!
Sorry to ask another question but since i have no idea.. whats a good overclock after these mods?? 600/1450??
Ok cool thats good to know cause i thought that maybe my overclock was'nt taking cause the one card is doing 600 right now. Kept the mem at 1450 cause i'm only concentratng on the GPU atm.
Thanks.. I'll be sure to report back when all is said and done.
Oh.. i'm glad the second card is done hehe. FIrst graphics card volt mod! Well 2nd if you count a pencil mod which i doubt counts. I'm used to moding motherobards.
I found the early OC series card hads little trouble going over 600 core on air but lately the cores haven't been nearly as good on the cards sent to me. Like everything else CPU/GPU related the production lots run hot and cold with some decidedly better than others. There seems to be a really good lot out there running around now though.Quote:

Viper
Well both cards are working great! Thank god.. hehe
Since i was in a hurry i just set the voltage up like you suggested viperjohn. Its good that i asked since i dont have the time tonight to spend hours on hours finding that sweet spot with the voltage.
The first card was stable at 611/1502. :) I tried 620 and i'm not sure if it was the card or the cpu but it errored out to the desktop. Tried 1520 and i got a funky striped screen right away.. so these numbers are enough to satify me thats forsure lol!
Second card seems to have no probs with this either.. I might try higher though it dont matter since both are going to run the slower card speeds.
What value does this one have ?

Small solderpad (C515) next to this one has 0 Volt.
I give 1.60v on GPU (OVP on) and 2.5v on MEM :D
That gives me 630\1750 :D
You have one very nice card!
If i make this alive again i think it should clock well.
I did the mod as in this thread: http://www.xtremeresources.com/forum...ad.php?t=37362
It was no mess and kinda "easy" to do.
But the card just dont work any more ?
People say this mod kills cards but other say the modder did something wrong.
What is true ?
Computer reboots 4 times with the 4th led blinking ever time then starts loading windows without gfx on 4th try.
Anyone here killed the card and what happend to you ?
I have 0 volt on vmem small solderpad.
Well i'm completely lost and really confused here.. The cards run the same benches at 490/1386 as it does for 611/1508????? How in the hell can that be!
I've heard of the temp bug.. but i've edited my bios and takin out the throttling and only left one performance mode period.. just the 3d speed.
I'm talking before mods i got 32,000+ and now i get 30,000-31,000. Temps are cold at 31-33C.
Exactly which benchmark are you running for these scores?Quote:

I've had a similar experience in 03, basically I'm so worried about how high up the wazoo I tweak my grafx, That i am usually lax about the rest of the settings for my comp that I use when running the other benches.
I only see a significant benefit from the volt mods in 05
-Weee
so i didnt read the whole thread yet (plan too soon)
but how hard is this to do traceless? Or is it virtually impossible?
You did something wrong.Quote:

If you are using 77.77 or later drivers you will not have temperature bug issues.

this is gonna be sweet !
so anyone, how hard is it to kill your card with this?
I mean Im gonna do a ton of soldering practice on a really old vid card of mine, to get a hang of small point soldering. So as long as i use the right parts, and the soldering is good, and i turn the resistance way up, im fine right?
That totally depends on the soldering equipment you use and your skill level.Quote:

can you recomend a good but affordable soldering iron?
And Im sorry to bring this up again but i was the first few pages and im really sorry about your dad, but it sounds like he was a beleiver and hes in heaven now
