Nice work on that mod too--looks awesome.
Yes i mean they stay better!!!But it rather looks ugly !!!I am not experienced in the aesthetics of the subject...

alright I got some lower valued resistors and that seemed to be my problem, with a 51 ohm resistor is is pulling 1.45 volts idling so it sohuld hit 1.5 at full load, going to do a vantage run juicing the core at 925 and see where it goes from there and if I successfully modded the OCP/ If it kick in I'll drop the OCP resistor value from 2.2k to around 1.7k and then 1.5k etc. until I get the voltage I wan't. 1000mhz or bust!

well it turns out I applied the OCP mod from the 8800GTS G80 so that explains why my voltage craps out above 1.44 volts. I found this post at XS that kind of explains my card but the OP is so old the pictures are no longer there so I'm not exactly sure what is required.

(page 6/7 show it best)

Unfortunately I seemed to have butchered the volt mod area so much im too scared to attempt to fix it and go for the real OVP mod. I still managed to get some extra memory speed out of it with the reverse memory mod (1.90v) but not enough to get this baby into the top 3 for a hwbot cup it seems. I have a job interview tomorrow so hopefully i'll have some extra funds coming to get somes cards coming w/o quimoda memory chips


well... looks like I blew the memory controller... card boots at .4v memory voltage, adding this card to the scrap pile and hoping for another golden apple like my pny to come by again

I tend to have the same lock with memory controllers. That's why I rarely mod the memory if I want to keep the card for any length of time.

Here's my 8800 gts g80 with vgpu & vmem mods with test points, I'll also post my before modding best vantage run (cpu wasn't OCed, only makes a few points difference so just saved it for a final run) & after.
The next core strap is from 729 to 756, at 1.44v idle 1.4v load I still get a freeze & driver crash even when I clock the shaders & mem down. No artifacting or anything first, is this OCP? was thinking on doing the OCP mod next...
The memory is at 2.05v & clocking great comparing it at hwbot, don't think I'll push it harder till it's time for suicide runs.

Modded card


Before mod vantage clocks


After mod clocks so far

well done, looks damn good

sounds like it could be ocp to me, this post right here covers that card's ocp:

http://www.xtremesystems.org/forums/...&postcount=546

there is also a link to the OP. that mem should be able to handle a little bit more, good luck with the hwbot reel it in for OCN!!!
post #107 of 553
Thanks man, I'm getting better at this. CL3P mentioned somewhere about using ribbon cable for wire, & it does make things much easier.
Card gave me 25 points today, still a few I'm behind on so hopefully the OCP mod picks things up a bit.
Anybody know what the max voltages for the gpu & mem are for water? Don't want to do suicide runs quite yet..

with gpu if u disable ocp u sohuld be able ot get up near 1.6 1.55 with water, ive done 2.21ish on mem on water, maybe 2.22 and that got some records for me, memory topped out there (samsung)

I use ide ribbon cable too, its the way to go for sure, the more you mod the better the soldering skills, I can confidrently replace resistors almost now

Those G80's can handle voltage a little better then the G9X's. Remember the Ultra came stock with 1.35v. I'll bet you can pump 1.45-1.5v pretty easily into her. ~1.6v will prbly be the death range. Just guessing here. There really is no 'safe' range unless you're clocking at stock

@ 420- ~1.55v on water..OCP mod'd

..as for your lock-up issue..sounds like lack of GPUv to me..and not OCP. OCP and OVP can behave the same way..once tripped, GPUv goes to .0v and black screen..reboot/power reset will clear things up. If you measure GPUv during your lockup..you will be able to tell if this is indeed happening or not. -Nice job on the GPU btw

..here are some more pics of Patchs 5870..OCP mod ready for VR and added 4x 6.3v 1500uf caps to GPUv output phases ..NAOW its ready for LN!





----------------



As well..here are some nekked pics of a fresh victim..just arrived from Newegg today!

Bastiaan_NL's GTS250.. in progress







Oh..and I have seen hwbot submissions for G80 @ 1.8v on LN
