All the mods were done by persivore
This guy has been great to work with from start to finish
Quick and efficient with updates and pictures sent at every step of the mod
Thanks for a job well done
Thanks also to viper j and malves for the mod
baz :)
wholly ****!
so how does it clock? :D

so how does it clock? :D
one the cards is going in the rig saturday with a vapo bolted to it
its going to get 1.6v (for now) vcore and 2.25 on the ram @ -50 if it dont blow up
i should have some nice 3dmarks :D
then both are going in for some sli action

Very nice, I can't wait for some benchies. How about some closeups of those solder points.
Wow! This is cool. I've been watching a few threads, but most of them ran off the boards, and I never saw if the mods were done or not. This is great news.
I can't wait to see the scores from that. Will they bug out at -50 or is that the point where they are still fine? I've heard 7800's have the cold bug, but haven't heard the fix or workaround. Was curious if they are affected at -50.
the card did suffer from the cold bug but has had a bios change
i have been taking this one step at a time
1st was to fix the vapo camshell to a 7800
http://www.ocforums.com/showthread.php?t=403071
2nd fix the cold bug
3rd vmod cards
4th clock the nuts out of one card
5th clock both cards in sli on air
6th clock both cards in sli using cascade setup
as you can see i am @ #4 and saturday will be benchie day :D

these are the pictures that persivore took
after he modded the cards
i will take some close ups :)

hehe we can have some fun in the 3d forum

that is so sick, can't wait to see results
o man, Props to persivore for volt moding a 5-6 bill card :D My "e-balls" arent hard enuff to do that ;P
lol i agree with BlcK... im still scared of pencil modding my X800 pro.. and it cost like half of yours... but then again im 14... so :p

agreed, volt mod on a $500 card takes a lot of confidence. I 'might' pencil mod my 6600gt's and they were only $130.

argh, pencil vmods are for poseurs!
Why shouldn't you have confidence? As long as you are grounded, have 20/20 vision (corrected), actually read the guide, and don't have a seziure while doing the vmod, there is nothing that can happen to the card.

I don't have confidence because I'm still slowly learning the art of soldering. Just messing around on old hardware when I have time.

Keep learning, and eventually, when you get to the level of soldering to SMALL ICs and SMD points (see the resistor on the P4C800 VDroop mod, same size as the 7800vmod, seen here (http://www.malvescorner.net/images/p4pdroop.jpg)), then try the mod. The mods on the 7800 are VERY easy, if I do say so myself.
And just looking now, the SMD resistors on the 7800 are many times bigger than the P4P droop mod.
Just don't get nervous, and it'll be easy. Act as if the card is dead, so its of no loss :D

Godofgorks,
These guys give good advice, and one of them (who shall remain nameless ;) ) gave me the gumption to do some mods on my board. There is always risk with any modifications you do to something. You probably were slightly afraid when you first clcoked that FSB up 1MHz (or maybe even KHz if you've been clocking long enough) weren't you?
Pencilo mods are actually riskier than soldering. They can cause varying results, and when you vary resistence, you vary voltage, and that fluctuation can cause instability, and in extreme cases can cause IC failure.
It is tedious heating a board, and I will not sugar coat that. People should be aware of the risks involved. They are pretty minor however. If you can solder two wires together, you can solder one onto a board, it's just a little different, and you have be be real still with the iron, use the right heat, and use the right iron. I have soldered stuff for years on small IC's, but I was a nervous wreck soldering ona something that costs 2000 dollars, but it;s really not that hard.
I'll tell you what is hard...pushing the dang button after you do it! hahaha That's harder than doing the work, and after you push that button and it works, you'll jump through the ceiling you'll be so happy. Even if didn;t give you a gain, the fact that the thing works is enough to make you feel like your on top of the world. It's cool stuff. Try it, but practice first, and you can do what "somebody who shall remain nameless" did on his board. ;) hehe
damn true
might I be the somebody? i'm confused lol

i have one thing to add to this
Never VMOD if you cannot afford to replace the part
as a new one maybe along time coming
i am lucky enough to know my own ability that is why i had the card Vmod
by a person with a proven record of success
kool stuff guys... keep it up and come on lets see some results. :) :)

Cmon bazx quit teasings us I wanna see you push it to the max, Im expecting 650 core min.

im running a 640+40 now thats as high as riva will let me
need to shut off the riva test any idea?

Ya go to power settings tab, than overclock, than change disable internal test value to 1

cool thanks for that
i am using a 3000 as my fx55 is on holiday @ sucka's being tested
i sure wish i had that 57 of yours right now
thats it for tonight

08-26-05, 07:23 PM
Why you send it to sucka?? Ya I wish I had a 57 too, mine died on me out of no where after about 2 hours of use, I took it out had it sittin in the little case put it back in and it was dead dont ask me how there was no condensation or nothing so its on its way to amd for testing =/, I wont have anything till at least thursday of next week

also, there's a sticky up there on solderin small components, written by yours truly :D. apparently people say it's a good guide, might wanan give it a read if you're considering a Vmod.

Here you go bazx,
Disabling The OC Test...
Open rivatuner>poweruser>rivatuner 2.0 RC 15.5/Nvidia/Overclocking> Then clicking on the disable internal clock test and mem clk reset protection.
I found it in the nVidia forum. Hope that helps you out. Now, I'm going to do that very thing right now. :)
thanks dude
there is going to be a hole lot of oc today :D
as my vapo is bolted to the 7800 i need to get a zalman for the cpu
to get a better oc
any one that thinks the cpu plays no part in 3d tests is wrong a tight system
can be 1000 points :)

It doesn't nail the highest stable OC at all, and everytime you redo it, it'll select a different wall. If I find out how to get rid of that, I'm gonna hack it in a minute...well, actually in a second.
I dunno about GeForce, (Nvidia) but with Radeon, (ATI) with ATI Tool, if there's suddenly a wall at a lower frequency then before, it's unstable.
I know that with a Radeon and ATI Tool that once there's video corruption, there will continue to be video corruption until you reboot Windows. Because then it will be unstable even when you lowered the frequencies.
With a GeForce, (Nvidia) I normally just run 3D Mark 2001 SE and then say that it's OK if there isn't abnormal behavior.
You also have to right click the selections and then click the little light bulb that says "set value to 1". After that, you still have to test, but the test will pass you everytime after that.
thanks it worked great
i have started a thread in 3d bench forum to continue this :)

i like viperjohn vmods.....always got neat lil fans with color panels and such....
def for sytle and performace VJ wins.....
Nice work on the ramsinks, I did something similar...
Good luck with the testing, I'd be interested to see if you get some significant benefits from the vmod. Any chance you'll be re-testing on air? I'm only using air cooling in my rig...

08-30-05, 11:15 AM
I will def be retesting on air, but I viperjohn gave me some of his results on air, 600mhz core no gemoetric bull**** so no +40, 1450 on mem, at 1.5vgpu, and 1.23mem artifact free in mother nature torture test loop, ill be pushing the card much further under phase, so you can expect a little more
Rivatuner or coolbits? I read you know about the rivatuner 'trick/hack', but even with the hack I was still having issues with throttling at higher clocks. Used coolbits with fan always on selected and it clocked a tad lower but scored better thanks to no throttling. Maybe I'm missing something, but coolbits seems the way to go for score and Rivatuner for pure clock screen shots.
600/1450 is probably not worth the mod for me. At least not for now. With phase/h2o I'd be singing a different tune though. Good luck! :)

That's what I did to get my 6800LE to OC. It's a lot better to not have to keep failing the test. I now click the test button, wait 3 seconds and it passes everytime. :D
Hi, it is old topic but I wont know more about this V-mod because I have same cards and I thinking about mod my cards. This cards are in Sli mode and they have stock cooling. So can I run this V-Mod on AIR or only on compressor cooler like vapochill?
And I cant find the results of overclocking on this modded card.
