OC my ati 4850 need some help

ok so i have this ASUS Radeon HD 4850 1GB (http://www.newegg.com/Product/Product.aspx?Item=N82E16814121325) 4850 but its the 512 version and for some reason i cant get it to oc much if any at all from the preset 680/1050 clocks. i even uninstalled ccc and installed ATI tray tools but its not a verified driver or some crap with windows 7 which makes the low level driver thing flip out on me and reset the video driver. so what im asking is whats my best course of action to get this baby up to like 740/1105 or so.

HI Klepto,
do you know how to disable driver signing?

no i dont :(

do you know the best thing for me to do without hard modding the card.

heres a couple of ways to do that

after you do that and get tray tools installed, you can add some vcore to the gpu (be careful start in small increments) to see if you can stabilize a higher overclock. I have my 3- 4850's OC to 725 with a .07v increase

ok thanks ill try that red if i have anymore questions ill post back

anytime Klepto :)

ok question should i uninstall CCC before using ati tray tools?

yes, i have always ran them in parallel with great success, as a matter of fact, when i went above 700 on my core, it increase the clock options upward in CCC.
and im sure you know that you can increase gpu voltage in Tray tools

ok i tried the first option and it still asked for signed drivers :(

driver signing is a huge pain in the ***, it took me three attempts and the second option to get rid of it. hang in there Klep

ok so i tried them both and still no dice hmm red are you able to run this in windows 7 rc 1

yes, i have it set up the same way on my RC7 partition

it took me several attempts to get the driver signing shut of as well.

i went to comand prompt with admin priv and it said operation complete but it still asks for the dang driver :(

did you try hitting F8 during the boot and selecting :disable driver signing'?

i know, if you read the forums it has been a hit or miss for people. i dont know why

havent tried the f8 thing yet ill restart and see what i get

ok red i did the f8 thing and i think it worked but will i have to do that everytime i restart the computer?

if you use that method (F8) it is a session based solution so yes

ugg that will suck lol

yeah it does...but if the only of the three....at least it will get ya to 740Mhz LOL

so i used the f8 and it still gave me the error upon installing ati tray tools :( i think im just going to give up this is a headache

uggh, there was another method of disabling DS, let me see if i can find it.

sorry red im not trying to be a pain i just really would like the extra performance from this card that i know it can do but ccc sucks and the voltage on these cards doesn't allow high overclocks

no problem, let me see what i can find. i think i saved it on here

i know what you mean, i have had my 4850's up to 770/1120,needed voltage though

buy a 4890 and call it fixed :haha:

j/p, I haven't really done any overclocking under Win7 yet so I'm not really sure what to suggest. If there was a way to manage the card and 3D settings without CCC (i.e. Rivatuner + ATT) I would maybe try that but I'm not sure RT can even run under 7 yet. Of course the real problem seems to be Driver Signing which I have no experience with, so I guess either figure that out or it's a bust. What about Beta drivers that are unsigned, would that yield the same problem?

yes a 4890 would be nice but im about to have a baby and funds are low i know with enough OC i can bring the gap between a 4850 and 4870 a little closer.

EX,
driver signing and the disabling of is a hit and miss proposition, you have to try it and find out. the forums are full of people flummoxed over it. i had to try 3 different methods 5 times to get it to allow UD's

not a bad idea though....3x 4890's :)

that sounds like a huge pain in the *** that i want nothing to do with lol...

sorry guys i had to run to town anyways wish i had a crossfire board on this system but only 1 pci-e slot :( kinda sucks guess ill leave it at stock for now. in like 2 months im going to grab a GTX 275 i think so that will be a nice upgrade. thanx for your help Red and EXCell :)
