XFX 4830 vmod?

[Mescalamba]

Sounds good for me, but should i email them or what ?
I just installed Zalman to XFX, let's see how this thing clocks now.
I have no heatsink on memory, i forgot.

I was just joking..

Heatsink for memory? Usually not needed but depends whats on HD 4830.. DDR3?

No-one tested these babies on water yet?

Did a run with a sapphire 4830 yesterday on dice. first test with 1.55v vgpu and 950/1280 flew past. No problems, had some trouble with my cpu after so i didnt have time to test more

Getting a waterblock this week for it How much voltage is safe for 24/7 use? Will the vrm's take dmg from to high voltage or what would happend?

If you have watercooled VRM, no need to worry I think.. should survive like 1.6-1.7V maybe.. 24/7.. hm probably something that allow you OC high and keep temps low or average? Only problem with voltage is electron migration and thats caused by high temperature and high voltage.. so if you keep temperature ok, no need to worry.. at least it works for CPUs.

Sorry, i will have the gpu water cooled. The vrm just have a pretty big heatsink on them (same size as the 8800gt had on their vrm). Then a chassi fan blowing some air onto it.

Should be ok, but really can't say how much it will survive.. it will have some limits and one of them will be heat and effectivity of cooling.. as usually.

Yeah but im aiming for 1.5-1.6v depending on temperatures and so. Will try and keep the gpu below 50-55C load. Got no idea really what temps to expect

How i can OC more with CCC ?
It only can make 700MHz max to core

[Mescalamba]

Download Radeon Bios Editor from techpowerup.com and look into Aditional features, theres way of increasing OC in CCC. Tough, useless for my HD 3870.

new riva tuner works well... the 9.5's did not like my modded bioses..

Riva Tuner dont work with Win 7

e. Tes, i try mod bios and i will do there 2D adn 3D profiles..

BIOS mod is probably best for permanent OC.. if you are sure, that card can handle that. When its working, you are free to use your card anywhere and reinstall your OS anytime and OC will be still there.

well with the two 4830's i have, with 9.2+ drivers installed. any of the modded bios's i have made black screen 9 out of 10 times after the windows loading bar...

Never happened to me.. wierd. Too high freq? Or too low idle? You have XFX? Or something else? Maybe some manufacturers have some internal BIOS protection which prevents. Still.. I've modded few cards this way and all fine..

Yes, I bios mod my 8800GT about year ago. I liked it, core 600MHz => ~745MHz
Shader 1500=>1800MHz and mem stock v 1800=>2250Mhz 24/7

I will now mod my HD4830 bios, first time mod ATI
I am not sure about the 2D clocks, i mean, will it work, so i dont touch them.

wtf
Windows can't find drivers, i already try re-install drivers but no.

I did flash the card in windows..i didn't find instruction how DOS
But i don't think thats the problem, i will try now XFX own bios.

e.
Aww..http://www.aijaa.com/v.php?i=4387142.jpg
DON'T touch that
