Help with ATIFLASH and BIOS settings

post #1 of 2

Hey guys

Basically, I need to flash my Radeon 5850's BIOS in order to prevent flickering on my second monitor. I followed a few guides with this being the most informative:

http://www.overclock.net/t/999024/ati-5850-dual-monitor-flicker-fixed

He owns the same card as me and according to the OP, all he did was change all the memory clock settings (Clocl 00 to 04) to 1000 Mhz.

Here is a picture of my current Radeon 5850's BIOS settings:



I mentioned above that the guy who changed his memory click values to all 1000 only had clocks 00, 01, 02, 03 and 04. With mine, I have 00, 01, 02, 03, 04, 05 and 06. Taking a gamble, I put 1000 for the memory clock on all of them, and this worked successfully. However, I am unsure if this is safe and whether or not I have done this correctly.

This leaves me with a problem and a question.

The ATI Radeon 5850 can be overclocked in the CCC override settings to have a memory clock of 1125. Foolishly, I changed the memory clocks of 00-06 on the bios to 1125. After I flashed the GPU and did a reboot, I could no longer get past post. I have now flashed back the default BIOS back to the GPU but I still have the problem with the flickering screen.

Basically, I want to flash my GPU with settings that prevent the flickering occurring on the 2nd monitor but also have the safe 1125mhz memory over clock.

What settings will I have to put in to achieve this?

I would be very appreciative for a response.

Thank you

J
