yes it will be okay. i used 500ohm for my 88ultra. max ohm for 500ohm vr i get 1.36V. yours set wrongly?

hi NightRaven, i think is right point you can see from pic.

if i change to 1k VR it will ok ? or how should to fix it ?

Thank

[NightRaven]

NightRaven -

I am going to voltmod my 8800Ultra Superclocked. I believe the gpu voltage on these cards is 1.35 stock !? With a 500Ohm VR you say you can get 1.36v, which is not much different. If I use a 1K VR will I be able to go higher than this e.g. to 1.45v. What is the highest voltage you recommend. I am currently stable at 698/1180 on stock voltage and water cooling. Runs at about 70C under load and 55 to 60C idle

the cards have OVP and wount boot with more than 1.55v

umm.. after i try between 500ohm and 1k, i like 1k than 500ohm it feel delicate for adjustment voltage ;)

[gaz_az]

Thanks then 1K it is !!

:)

[NightRaven]

haha but i prefer 500ohms :) it all depends on what kind of vr u use. if multi turn one then 500ohm is fine if normal hand turn vr then 1k is less sensitive yes :)

@Zol u going to china too? :)

Really? Mine had no problem at 1.638.

Can you please post one or more pictures to show the complete vMod for the 8800Ultra? I can't find anything. I have 2 Ultras and I would like to vMod them to ~1,45v, I have water cooling. Will it be ok for daily use?

Here are a couple of picthures, i have posted this on a swedish forum so the writing is in swedish, but i think you can figure it out, if not, then please just ask and tell what you didnt understand and i will try explaining it to you.

Also it should work fine to use 1.45 24/7 if your temp is OK.

For this modd i have used a 500Ohm´s VR, you can use VR somwhere between 400-1000Ohm.

This is the workspace where i usually do my voltage mods, because its a small solder point its important with good light, i also use a magnification glas.

I hope this helps you to better understand the modd.

I can write a couple of words about the mod if you want, but right now i am working so it will be later today. And if you have any questions then please just ask.

Thank you for answering. I am new to vMods on VGA cards, so if you can I would like to read something more about how to do a good vMod on the 8800Ultra.

This helps thank you just what we needed:up:

Can you 2B pencil the vgpu resistor?

[largon]

^No.

[TheKarmakazi]

Thx Largon was hoping for an easy one :p:

In my GTX if I put more than 1.360v the card shutdown in games... :(
