Mine is Factory OC card..

for me it's normal..

I got weird texture on SC2 using the TwL Modded CCC 10.7a Beta(Final 3.75 Build) sometime(seldom). However, I don't really care about that. LOL.

its not only factory oc'ed card have voltage lock, any non reference board is voltage lock, like mine.. XFX 5850 (non reference and non oc).

With stock voltage i can only do 865 / 1150

My HD5850 idle at 40C but mine is Powercolor PCS+.
54C is a bit too high for idle to me. What case u using? how is the airflow?

my room temp already 36~39 temp. 50c is normal for my system ler
Overall system temp: 71'c after Dota

LOL enlighten me please, i've been using MSI AB for years. Check the attachment.



Based on what I read everywhere, there is no way you can change the voltage on non reference card (unless bios hack).

non reference card is not only factory OC'ed card.

just like mine, it is non reference card and it is not factory OC'ed card

it looks like this: http://www.vgadownload.com/wp-content/uplo...eon-HD-5850.jpg

like i said before..

reference design card voltage easy to unlock with msi afterburner..

in your case..

i just know that u not using reference design card..

msi afterburner is easy software yo..

even first time oc can handle this sotware..

how to do bios hack? it is risky?
my 5850 also cannot change voltage with afterburner

There are alot information you can find in some forums. Do google it.

I'm interested with this one, but I'm still busy right now. I know doing this thing have to be carefully and patient.

from u guys observation..
which is the coolest 5850?

i see. Not sure what is my room temperature. My room must be in nice room temp.
Usually gaming will maxed <60C.

all the brand with hd5850 is the coolest..

i recommended to you to go for references card design for easy future overclocking..

recommended Asus and Sapphire ..

Gigabyte is a good card too..

same with XFX reference design..

they said they r using driver 10.4 and how bout yours?

im still using 9.12hotfix my reference 5870 stock also 40c

for the lowest temp of course..
if none of them are premade.. better still smack aftermarket cooler..

Asus and MSI non-reference boards also have good OC capabilities due to SmartDoctor and Afterburner software support. Not sure whether the custom cooler for the 5850 DirectCU is good enough though as HardOCP found it inadequate for the 5830 version.

Did you ever hack your registry entries for your MSI Afterburner?
If you doesn't, it won't work.

I am using the 10.7 official driver. But no oc. My card comes with factory over clock. The powercolor heatsink look really nice and it cool down nicely too.
