I have set-up my new 2900pro, but I have a problem with the card stuttering badly in games. 3Dmark benchmarks also stop responding when I double click on them to load up.The performance is worse than my old 7800GT, which cannot be right. BTW I am using the latest ATI drivers.
My computer specs are:
Vista Home basic
I am guessing that it could be my PSU causing the problem, but I am not sure. I only had one PCIE power connector, so I used a 2xMolex to 6Pin PCIE power adapter for the other. Could it be my PSU that is to blame?
The manufacturer will inform you that you can not use a 2 to 1 adapter, it wont work and it should be written somewhere in you booklet.
New psu is your only option, in theory using an adapter sounds correct but its not.
I have purchased myself a new PSU, which should be more than capable. The new PSU has not solved anything and I am still experiencing stutter. I have tried re-installing the ATI drivers, but this does not help. My games are running like crap and I am out of ideas
i would use driver cleaner if i were you, and reinstall the ati-drivers, check your temps, make sure that there is now power cabling near your computer that gives off alot of EMI, you'd be suprised at what that can do to your performance do NOT doubt that. It has happend to me twice now in my life.
If the new PSU doesnt work,
and none of these work.
Then call tech support, and inform them of this, you cannot doubt the possibility of a bad card.
Tried cleaning the drivers as suggested, but that didn't improve things and I even went to the extreme of re-installing Vista with little luck. I'm considering whether to re-intall Windows XP to see if it can bring some joy.
An issue I tell people who buy ATi cards is this: The thermal paste use don the cards soemtimes doesn't melt and allow proper cooling for about a week. I would check those temps, note what they are, and see what others are getting.
And don't regret your purchase of the HD2900 PRo over an 8800GTs. for all you know, the 8800GTS could be having the same problems and you might be saying you'd regret purchasing that instead of the HD2900 PRO. In the grand scheme of things though, it did force you to buy a new PSU, which may sound bad, but hey, at least you won't have to upgrade later on for quite some time. Try to stay optimistic.
