8800GTS 512Mb (G92) vMods

[rocketr2]

I have a quick question. What would be better ? An overclocked 8800gts 512mb 900core-2200shader-1150mem, or an stock dual 8800gts 512mb SLI setup.
I ask this because the overclocked gts scores around 18k on 3d06, and the stock SLI setup gets around 15-16k on 3d06.

Anyone ?

Anyone ?

You shouldn't base 3d mark results on what would be best.. If your into gaming I would go sli, if benchmarking is your thing stick with one card.

MoosePower,
How's that?
Infact, SLi/CrossFire is just for benchmarking. Single cards for gaming.
Multi-GPU is nothing but a pita for a gamer.

I'm not for benchmarking but for gaming. So I should go with the single card max oc ?

[Vivi]

yes that would be best. keep it nice and cool, not too high volts

[Gir92]

Pardon the noobness. I am good with computers, but know next to nothing when it comes to electrical.

What exactly makes it impossible to pencil mod the G92 cards?

Thanks.

Too low mod point resistance (FB-to-GND ~15Ω).
Applying a parallel high resistance resistor (pencilling) would have practically no effect on the total resistance - and as such vGPU - with such a low mod point resistance.

Anyone,
I have a MSI 8800 GTS 512 that I would like to volt mod. I have already purchase a water cooler and now i'm going see which water block to buy. Its either going to be one that only covers the gpu or one that covers the ram and gpu. But i'm a complete noob , and I wanted to ask if it would be possible for anyone to volt mod the gfx card for me. I could send it you and pay you.
Let me know if this is something someone could do.
Thanks

Honestly dude, it's not extremely hard to volt mod with the instructions that all these experienced people give you and I think it would end up being better if you did it yourself. Also, make sure it wouldn't just be cheaper to buy a new card if you REALLY are going to ship the card out to someone to volt mod it and then pay them to do so.

[Loser777]

It depends how much experience you have with soldering... if you're seriously worried about soldering, I say get an $8.00 iron from radioshack, some solder, and a cheap soldering project kit. You won't need much more experience to do a voltmod.

[CryptiK]

Yes, I also recommend soldering wires on to an old dead motherboard for practice. I soldered to one a lot getting ready to voltmod my old GTS, and when I did my card I wasn't nervous I just did the job. FInd small areas similar to where you are going to mod you vid card, and practice getting it just right, it will help a lot.

[Boble76]

First I wanna thank for the instructions.
I only made the vGPU-mod and it works just fine. 1.16V @ 1.32V so far with H2O. Without this mod I could OC the GPU from 650 to 810MHz max 3Dmark06 stable, now It takes up to 875MHz with 1.32V and water about +25C. GPU Idle +33C, on load (?) don't know..maybe +45C? I 've MCW60 block on GPU. No heatsinks or aircoolers for Mem chips..
Shaders tested 1910-1920MHz, MEM @ 1120-1130 without any mods.
More tests in future.

Some pictures of my card and tests.

edit: vGPU @ 1.39V (900/1910/1110) 3DMark06

[trez0r]

I'm wondering if anyone using air (or even water) with a vgpu mod can run the dreaded furmark for more than few minutes?
I can do it for hours long w/o mod and freq 800/1840/1060 on accelero s1 and hit t° around 67°. As soon as i switch on the mod with a modest frequency and voltage increase furmark will just crash my card in no time - in around 3-4 minutes the card will hit the 76° and freeze lol. Of course i can run bechs like 3dmark and such w/o problem and not hit t° above 50° but the thing that furmark destroys the card in a few minutes makes me not like the thought of using the card with a mod at such settings for everyday use.

[jason4207]

IMO furmark is very hard on the card, and especially volt modded cards. I use ATI tool to get a general idea, and then just use actual gameplay to decide if I need to go down a bit.

I have 9600GSO card, but chip is the same as 8800GTS. Volt-modded to 1,3V (original 1,21V). Cooling is TT DuoOrb. When using rthdribl 60C is max, but when I start FurMark temperature is rising to 73C. On higher voltages I saw 90C one time Games running well except Colin McRae DiRT, which freezes with voltages higher than 1,3V on any clocks. I'm thinking about add on/off switch, because this mod is useable only for benchmarks

[Gir92]

Is 1.39v under load fine for regular use on a GTS? It never goes above 40C.

[doomwill]

No vmods , My assinature ;

[Gir92]

Bump. Can anyone tell me what the max safe load voltage is for everyday use please?

[Zeus]

Only stock voltage is safe.

Anything over this is up to you to decide what is safe and what not.

Things you might want to consider are your cooling solution and for how low you want to keep that card.

Temps never go over 38C, so that isn't a problem.

I'm trying to ask what is the max safe voltage before it starts to degrade rapidly, IE: 65nm C2D at above 1.55v and 45nm C2D at above 1.4v

[Zeus]

I would run stock voltage for 24/7 usage.

What do you want out of your card and how much will you gain by overclocking it?

If it does 800/2000/1000 on stock voltage i'd keep it like that.

How much do you gain by raising voltage so you can run 850/2200/1000 in everyday usage?

Not worth it for me, vmods are for benching, nothing else, just my opinion.

[Gir92]

I don't mean to be rude, but you still haven't answered my question.

Can you give me some sort of number? IE: If you go past 1.4v it will degrade at a much higher rate than at 1.35

[Gir92]

Ok I'll put it this way lol.

For those of you who run your vmods for everyday use, what is your voltage?
