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!

Try each card individually? Sounds like at least one is faulty.

And welcome to the forum, btw!

It only does it with the full 8 gig of RAM in? fine with 4?
If thats the case then sounds like the RAM is causing extra system instability, not uncommon when using all 4 DIMMs
Ensure your DRAM voltage is manually set to correct level in BIOS, and try bumping your NB voltage a couple of notches, that should alleviate the extra system strain of using all 4 DIMMs

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

i use vista 64 with 8 gig and its great. Maybe some faulty memory or slots.

your memory will be fine
try running at default bios settings [optimised defaults maybe]

also make sure you are running the latest version of 06

is there any games that the problem is occuring on? i noticed a significan amount of tearing on screen when i was benching with two of these cards

 

[Stalker_26]

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
