Can I raise 3D voltage from 1.4v to 1.5v AND throttle from 1.2v to 1.4v? Will it work or fry my card? Anybody tried that? Leadtek A400 6800.
that won't do any good for your card. the only value that matters is the throttle one, cause it's the one that ends changing the "real" performance voltage in the end...don't bother with the others. (i'm saying this based on what Unwinder told me)
Hmmm - i have the same probllem like BENCHMARKMAN.A turned on this disable test... and i overclock core and memories to 875/900 and all looks fine in 3dmark 03 and aquamark - and my question is - what is going on - i dont have artifacts anywhere (games, benchmarks)but rivatuner test dont pass - y ? ohh - one more - RT can test stabillity in 0.5 sec ?? - this time take to show error :/ ??
weird problem i have a weird problem after activating to 16/6. don't have artifacts or anything, but my 3dmark03 score droped about 1000 points, but 3dmark05 went up 500 points. tried with different drivers but no change. another thing i've noticed, that fill rate test (single texturing) and pixel shader 2.0 test results decreased, while fill rate test (multi texturing) and vertex shader test results increased... weird ey?
Sorry Unwinder, Just For the Record, Pixel Unit 3 and Vertex Unit 3 were the masked units, You know my success story
Hi again. If i am spamming, i am sorry, but can someone plz tell me how to increase Core voltage. I have never done it before, so i don't know which programs to use and so on. Do i have to flash my 6800LE with a NU bios, or can i change the voltage through the original bios?
Look for OmniExtremeEdit, and look for nvflash. Use nvflash to get a copy of your card's bios into a .rom file. Use OmniExtremeEdit to change the Throttle voltage of the bios file. Reboot to DOS and use "nvflash -4 -5 -6 <bios file>.rom" to flash.
oh man i'm so lazy... but ok i'll write it. you must get two tools, NiBiToR 1.6 and nvflash 5.08 (google 'em and you shall find them). then, u must extract your own bios using nvflash: get a bootable floppy, put nvflash in the floppy, reboot to DOS prompt and type a:\nvflash -b backup.rom reboot, go to windows, run NiBiToR 1.6, "Open Bios", choose the file "backup.rom" wherever it is, change the value(s) you want (in LE's case i don't know which value you should change, in NU's its the Throttle one that matters for performance voltage), then save bios as a different name (something easy like 123.rom), put that file in a disk, reboot to DOS prompt again, then type: nvflash 123.rom answer YES when it asks you, let it flash, then reboot, you're back on windows and it should be all ok. keep in mind the temps of the core, and if anything goes wrong, just reboot again with the floppy to DOS prompt and reflash to your previous bios (nvflash backup.rom) about the settings @ NIBITOR, i just set the core to 350 and the mems to 400 (800mhz DDR) cause that's a mild overclock and doing that u end up having those speeds "stock", i.e., when u boot up ur card is always @ 350/800, of course u can change the clocks anyway. the voltages are the problem, from what Unwinder told me, author's of NIBITOR messed up some of the ID'ing of the voltages and for example in my case, to get to 1.4v from 1.2vstock i just had to change the "Throttle" value. since u seem a little newbie in this kind of stuff, please be extra careful when changing settings in your bios, and remember to always have your "backup.rom" handy to flash back to original bios if anything occurs. hope to have been of some help (tired of writing now, i knew it :wanker: ) greetz, peace
hmmm...why -4 -5 -6 ? i just used nvflash file.rom and it worked fine...oh and btw, OmniExtremeEdit has been renamed, now its NiBiToR (NvidiaBiosEditor)...greetz
That's weird, but thanks What's confusing, is that the proggie used to modify bios shows my 3D as 1.4v... I wonder if that's correct (probably not?) and if I can check somehow before I flash what's my current voltage, with some monitoring software... nVidia System Utility maybe? I'd like to make sure that my voltage is indeed 1.3v

I'm reading: So I'm still wondering which VGPU setting to change in Nibitor for LE..
Can be done thru a CD-ROM drive. You need a boot cd-rom disk that takes you to a DOS prompt. Its possible to do it thru a cd-rom drive and not need a floppy. I did it that way once, when I had a system that didn't have a floppy and needed to boot into DOS prompt. Sincerely, Bitpower
-4 -5 -6 is to force it. I always do it out of force of habit, but it will work without them if you're flashing with a bios "meant" for the card.
evga 6800. origional BIOS, stock speeds. standard voltage. successfully modded to 12x1,6vp. tried 16x1 but i got some really weird artifacts. text would garble up or shift and various textures would break up into what is best discribed as triangles with color that is slightly off what it should be. i did NOT see any snow artifacts tho. i was hopin for 16x1,6vp, but 12x1,6vp is still an improvement
First post on the forum, felt the need to register just to thank Unwinder..... Here's my results.... OEM 6800LE (Leadtek according to RiBiTor) From 8x1, 4VP to 12x1 6VP. Quads 3 & 4 HW masked, 3 OK, 4 non-functional (artifacts in RTHDRIBL). VPs 4 & 6 HW masked, both OK. Artifact free after 5-6 hours testing with 3DMark03 / RTHDRIBL. Have fitted a socket A HSF (Ally / coppper core / 60mm Fan) and copper BGA ramsinks. Set 1.4V VID with bios mod (RiBiTor) Have achieved stable OC of 420 / 890 at 12x1, 6VP (45c idle, 52c load, 35c ambient). 3DMark03 (12x1, 6VP, 420/890) 2,980 Single Texture 4,856 Multi Texture 151 PS 2.0 10,707 Total Score On XP-M 2500+ at 2.6Ghz.... All for £135 for gfx card and £15 for cooling mods (UK), am most pleased Thanks again Unwinder...
UGH!!! My BFG 6800OC finally arrived today and it doesn't work. Tried it in two computers and neither would show anything resembling normal graphics. The BIOS screen looked like it exploded. Time to RMA and wait to post my results.
your voltage is 1.2v. u can be sure of that. its just that nibitor shows the wrong voltages. the Throttle voltage is the "performance mode" voltage. don't look at the 3D voltage, it really doesn't matter. anyway if this is all confusing, you can check my posts and Unwinder's in THIS THREAD greetz
