3.19v is crasy but good for overclockers who dosen't wanna mod. But saw that already in your BS guide.Quote:

No need to test/measure, since the problem (voltage of 3.19 V, NOT BS-oddities) is SOLVED:Quote:

.. I fixed it :banana: and now I have stable ~0.02 V (AC) 2.72 (DC) voltage in that node (I will post details to 'Black screen guide').
(But there IS still an AC-voltage in that node having frequencies above multimeter capabilities. I have measured them with oscilloscope from non-faulty card = I had just BS and it is *feature* for GW not a faulty)

For extreme overclockers this was some kind of benchmark: Has anybody before tested with a 3.19 memory voltage ?
Good, that you could fix it. Did it overclocked better with 3.19?Quote:

That was a nice indeed. I wonder those memories would not stand for long time so high voltage. I can not understand HOW such card was sent to customer (=fault was not detedted) !!!Quote:

Yes, I think that those 6200 etc. cards have tatally different memories (too lazy to check now), so they have different 'absolute maximum ratings'
I can't messure the vdimm from TP1, anywhere else i can try?
You can measure Vmem (Vdimm ?) from TP1 or TP10. Please take a look this thread:Quote:

..where a much more easy way to modify Vmem is presented. There are also posted some OC-results for Vmem and Vcore.
great thread, just wish it was summarized a bit...
Getting ready to mod my Leadtek 6800LE, probably go with a bios mod 1.4-1.5v and a Vddr mod + maybe the cap mod.

At least I would suggest to include following figures, since the provide better way (easier etc.) to do modifications than originally proposed:
Capacitor mod for 6800le (to avoid 'Black Screen'):

Vmem mod for many 6800/6800le-cards:

(original thread for this, having also comments about Vcore modification)

I will speak to hime about this.
He has alsow made a frensh version that is much more updated. I will make a translation coworking with him. Dident care that much but now I goot the Pci express version of the 6800 nu so Im up for modding again :D
I will report back when I hear from him :)
EDIT: Just spoke to him, he has very littel sime at the moment because of a summer job finasing his studies :)
But we will descus what to do with the thread tomorrow when he has more time.
I will use my time to clean the thread up, but would like some help. So if anybody could give me a hand and cume up with suggestions for what posts to put where.
1. An updated guide.
2. An results part.
3. An FAQ part.
4. And offtopic.
I have problems with my card :( It's a Leadtek 6800GT AGP. On 1,3V everything is ok I can o/c on AC to 415/1150 and to 440/1190 on peltier+WC. When I change voltage to 1,4V I get screen corruptions, and resets.
Capacitor mod for 6800le (to avoid 'Black Screen')
Migth need somthing like that?
never head of problems with past 1.4 Vcore.
maybe you need capasitor mod?
Maybe :) When I can find that for 6800GT ?Quote:

I wonder Leadtek 6800GT have totally different PCB (=card) and design i.e. capacitor mod does not help. In the case of BS computer freezes right a way totally not only some corruptions.Quote:

Peltier element sounds cool cooling solution (literally!)
im not convinced that the leadtek GT has a different PCB.Quote:

Take look e.g. this foto (is the same card your were talking about?)Quote:

.. and compare it e.g. GW's 6800le card

Where can I find voltmods to mem and gpu for Leadtek 6800GT. I´v tried the one on VR-Zone (the Asus version for the mem volt), but it killed the card. I allsow want to have pictures where I can put the cap mods om my card. 12v 3300uf is the best cap?
I wonder the mods shown VR-Zone could be used with Leadtek 6800GT, since it has the same PCB (?)Quote:

I'm looking for the same :)Quote:

What did you in detail: a pencil mod or changed resistors ? Problem with pencil mods is that it soooo unrealiable: final resistance may vary a lot from target value and it can also change when time goes. Could you measure your current resistance and voltage values (DO NOT MEASURE RESISTANCE WHILE POWER IS ON)Quote:

Just a quick question, where is the measuring point for Vgpu??
Oh and the cap mod worked like a charm! Great mod!!!

You have a Leadtek 6800le (?). Take a look this figure:Quote:

TP1=TP10 (memory voltage)
TP11 (GPU voltage, small resistor 1 ohm)
TP3, TP5 (VTT/VREF voltages)
TP9 = GND (also some other TP's)
.. this foto is taken from GW6800le, but your card should be similar.

Did you get 'black screen' feature with your card or was the mod only for OC'ing ?
SikaRippa,
Your mods and pic's have been exemplary.... thank you!
And the cap mod stabilized my OC'ed clocks. I'm stuck at about 900 benchable at the default 2.7v... but this was still sufficient for the new 6800LE WR in '05 with approved drivers.
