I have problems with my new graphics card

post #1 of 7
Thread Starter 
I don't even have a week with my card and I can't make it work properly. I have a XFX R7750 2GB and it is giving a very low performance. In some games it causes glitches and other games run with lag at Low or High settings without a difference between both settings. Also let the computer for a couple of hours without running something and the fan stopped.
I think my card is faulty and I need to change it but the support page is under construction and I don't have a close store to change it there.

I tried using HDMI and VGA, updating drivers and everything is as it was before.

there are a few points that I would like to point out.

-first we (on OCN) need to know more specs of the system you are using this card with (CPU, Mobo, ram, PSU and what ever else you are able to provide).

-second I have seen a video or two where people like newegg or other sales site reviewing some of these new cards and saying that they have a feature where it turns off the fans when you are not using the computer at all. When the card's fans stop, and then you go back to run a game, do the fans start again? if they do, that means your card has that feature.

-third make sure you have the latest (or second/third latest) drivers from AMD. i am not sure what their latest drivers currently are since i do not own any AMD graphics cards. but you can check it out on their website.

I hope that helps

Assuming you are using your HP system a 300 watt PSU is insufficient. You need at least 450 watts to run that graphics card.

oh yes, i did not notice your second in your sig rig.
I agree, that 300 watt powersupply is insuffcient for your system.

300 Watt PSU = Limiting factor. Upgrade and you should be fine. The drivers are most likely downclocking to compensate for low power.

HD 7750 uses <200W under load for the whole system. It's likely that the PSU is just not a quality PSU: i.e. not enough enough amps on 12V rail

A8 only uses 65W , HD 7750 uses ~55W

check out

150W (i7-3370k@4.4GHZ). www.rwlabs.com/article.php?id=743

Could you open up your case and post a picture of the power label on the PSU?

Should look like

edit: also make sure you have it set to the HD7750 instead of the Radeon HD 6530D

Ok I missed the information about my system.
Hp pavilion p7-1254
AMD Quad Core A6-3620
8GB DDR3 RAM
1TB HDD
Acteck Blazar 600 W Af-b600p
Windows 7 Home Premium 64-bit
Motherboard Pegatron AAHD2-HY (Holly) http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03135882&prodSeriesId=5187022

The problem with the fan was that I had to reset with power button because I didn't get any signal from de computer.
Any other recommendations to try about setting my graphic card.

Thank you for your comments smile.gif

EDIT: I solved the problem uninstalling the drivers and all AMD software, but the fan still freezes when windows goes to power saving and turns off the screen.
