Topic: Underclocking Memory Help (Read 742 times)

Hey Everyone,

Im hoping i'll find some help here.....

I'm looking for some help to reduce GPU Temps... Primarily through the reduction in Memory Clock Speed. I have read several threads and done everything they say, but i'm running into some problems. Mostly the blue screen of death.

Rig #1
2 x Radeon 5770, crossfired (runs at good temp, mid 60's)
1 x Radeon 5970
Wndows 7
MSI Afterburner 3.0.0 Beta 9
Catalyst Control Centre/drivers 11.12
**I did at one point have AMD GPU Clock Controller installed, but it couldn't recognize any hardware**

I decided to open up the 6990 to clean it up and add some Arctic Silver 5 for better heat dissapation due to other cards getting great results. Well... I think it was one of those things, if it aint broken, don't fix it! Before, @880MHZ and Memory @ 625Mhz, both processors would be hovering around the 80^c. Still fairly hot, and this is with other fans circulating air. Now i've had to underclock @ 750MHZ and 625MHZ memory, it's still hovering around 80^C. I've tried this Arctic Silver 5 on other GPU's with great results, so not sure what happened here. Anyways, it could have been the Thermal Pads for the Memory, which I may replace later on. But they looked good and intact. Anyways, before I do anything drastic again, like by a Arctic 6990 Cooler or clean out the 6990 again... i thoguht i'd try underclocking my memory to 300Mhz.

I've tried the two main things i've read in forums:
- edit the CFG file
- Bring memory down to lowest, closing Afterburner, then opening to reduce more...

Neither worked! 

I was hoping that altering the CFG would have worked, but I kept getting the blue screen of death after about a minute of Windows starting. Or after immediately opening Afterburner. Also, I altered all CFG files while under safemode. I cant edit CFG while in non-safemode.

Can anyone help? It seems every CFG file i see edited to work is different from the next. Do I have the right drivers... etc... etc...

Anyhelp would be greatly appreciated.
