help with compaq 6820s, x1350 & win7 64

[ClareR]

I upgraded to 8 GB (2 x 4 GB) RAM on my old laptop HP Compaq 6820s, but right after I did that the video card had problems - Code 43 error.   ATI Mobility Radeon x13560 has the latest "official" driver from ATI, 12/1/2008, 8.561.0.0.  

I have Windows 8 Pro 64-bit.

If I put back in the old 4 GB (2 x 2 GB), there is no error.  

Any ideas why that is?  I like having 8 GB available - brings new life into the old laptop.

I found this discussion on modifying drivers.  Will something similar work in this case?

Please help...Thank you!

Hi:

See if this works for you...

Uninstall the Radeon graphics adapter and driver in the device manager and restart the PC, so that you have the Microsoft Basic Display Adapter listed.

Download and save but do not run this Vista graphics driver.

8.40-

http://ftp.hp.com/pub/softpaq/sp36501-37000/sp36784.exe

Then download and install this free file utility. 

The 2nd file at the top of the page is for 64 bit.

https://www.7-zip.org/

After you install 7-Zip, right click on the graphics driver file you saved.

Have 7-Zip Extract to:  And let it extract the file into its folder name (sp36784).

After that is done, go to the device manager click to expand the display adapters device manager category.

Click on the Microsoft Basic Display adapter.

Click on the driver tab.  Click on Update Driver.

Select the Browse my computer for driver software option, and then at the bottom of that window, select the Let me pick from a list of device drivers on my computer.

Click on Have Disk and browse to the driver folder 7-Zip created>Packages>Drivers>Display>LH6A_INF>CH_51345 (Setup information file), select the ATI Mobility Radeon X1350 graphics adapter, and the driver should install.

Then restart the PC and see if you can use 8 GB of memory then.

That worked perfectly on this old HP Compaq 6820s running Windows 8 Pro 64-bit...thank you!! 

Who would have thought an older driver would fix the issue...wonderful!!

Will it work on another HP Compaq 6820s running Windows 7 Pro 64-bit?
