Problems with Vista

[Stalker_26]

Hi All.

New to forums so bear with me lol!!

I have vista ultimate 64bit, 2 ATI 3870x2 gpu's, 4gb of ram, n it all runs sweet on a 32'' full hd tv, when i install 8gb of ram, (which is my mobo max) to try to run 3d mark06, my graphics go all screwy, i can no longer run at res 1920x1080, infact it runs at some stupidly small res, i know all of the 4 x2gb sticks are not faulty, neither are my ram slots, i also have ample power running to my machine, plenty of airflow, i have tried 3 or 4 different driver versions, even tried running just 1 gpu, but all to no effect, so any ideas on what could be causing this issue?
Also, my system recognises all 8 gb of ram, but i cannot adjust my res.
i get a message with something like 'Catalyst has stopped working, please update/rollback'

Please help!

my ram can run @ 2.1v optimum, so i have set it to that, i'll let u know what happens when i remember to press 'delete' on boot up lolol

no games have been tried, its the screen res on my desktop as soon as i start my rig, i dont even run any other programs (i assumed ingame it would the same)
All of my bios is set at default except ram, but i will try that just incase.


@ Leeroy, not that bud, i have tried all 4 sticks in all 4 dimms, n even in my other rig.

I have benched the 2 cards b4, but with 4gb of ram and they work great, only when i have all 8gb and start my pc does the problem occur

although this post is now nearly 5-6 months old, i have found the solution.

VISTA

I installed Windows 7 yesterday, downloaded the exact same version of CCC i was previously runnin, and its fine, W.7 see's, and uses all 8gb.
So now my only problem is going to be finding something that will utilise all that ram!

Damn Vista
