Hi Guys,

I have a Asus 5870 connected to two iiyama 18inch (1280*1024) and one HP 24inch lp2475w connected via display port (using display port cable native attach).

The HP randomly flashes on and off

I am using windows 7 64bit.

Any suggestions? I have been through the forums search and have read people flashing their cards. How can I find out which firmware I have currently, would it be worth flashing?

I have a 850W power supply. Would it better to use a second card (which I already have) for the two iiyama and use the dvi for the 24inch HP on the 5870?

I am not using any eyefinity setup, just standard windows multi display. Windows 7 64bit. The card is in stock mode. Although I have over clocked my CPU.

I have tried connecting one iiyama via DVI and the HP via DVI and the second (third monitor) via a different graphics card DVI. I still get blinking screens?

My card already has the latest bios.

Thanks

Snake

It is an issue where the 2d clocks are getting to a low point when in powersave mode. I would create a profile and change the 2d clocks for now.

Thanks for the reply. I just wanted to point out, this happens when playing a game (3d) also as well as during normal desktop (2d).

So just to confirm, the 2d mode clocks drop and the card goes into power saving mode?

How would I create a profile? and what should I set the clocks to? (is this done in the bios or with some asus software?)

Thanks

I just edited the profile that ATI's uses. It is a XML file, never used the Asus stuff before. Never heard of this issue when in 3d mode

1. Open CCC

2. Unlock and Enable Overdrive if they aren’t already.

3. Go to Options/Profiles/Profiles Manager. Create a new profile. Under composition make sure “ATI Overdrive” is checked. Save and Close, DO NOT ACTIVATE.

4. In windows go to: C:\Users\{yourusername}\AppData\Local\ATI\ACE\Profiles (you will need to have “show hidden files” turned on for this)

5. Open the xml document with the name of the profile you just created (notepad is fine)

6. Change the values of the Clock and Memory speeds to look like this (these specific values are what worked for me and my card, use judgment) EDIT ONLY THE BOLD VALUES.



Feature name="CoreClockTarget_0"

Property name="Want_0" value="40000"

Property name="Want_1" value="60000"

Property name="Want_2" value="85000"

Feature

Feature name="MemoryClockTarget_0"

Property name="Want_0" value="90000"

Property name="Want_1" value="90000"

Property name="Want_2" value="120000"

7. Save and close. Go back to CCC and activate the profile you just created.

This will make the card idle at 400core, 900memory. (2D clocks are the "Want_0" values)

Yeah I realised that later on. However I found that the display still blinks via Display port (using DP cable to DP port on HP monitor). However it seems to working fine on DVI now.
