Sepphire HD7850 low FPS! help!

post #1 of 19
Thread Starter 
Hi!

I just bought a HD 7850 2GB and did some benchmarking using unigine Heaven 2.5

I got 6-12 fps and score of 165 (very low compared to reviews)

I plugged my video card in the second PCIe slot and gave me higher FPS (19fps) but still not that high as it usually gets.
World of tanks all on max and i get between 18- 35 fps and some times 45-50fps. I know ppl who own same GPU and they easily get over 80fps. Hitman Absolution benchmark - setting all on max and results are: min 0.2 fps max 5fps and average 3 fps....

My PC:
CPU : AMD Phenom II X6 1055T 2.80/3.30 GHz
Motherboard : ASRock 880G Extreme3
Memory: 12 GB
PSU: Sirtec 400W (300w +12v) http://www.highpower-tech.com/eng/product_page.php?class=20100527154213&id=20100530203201

On the video card's box its says: 500W (or greater) so could the prob be from my PSU?

I'm pretty sure it's your PSU which is the problem. I'd recommend not using the card until you are able to get your hands on a bigger PSU.

It could damage the video card?

Yes, under powering components can lead to them being damaged. It's more to do with the demand you're putting on your PSU though. When you have high demand on a poor quality PSU it can easily lead them to fail. You might want to wait for a second opinion on this but I'm pretty sure it's your PSU.

I have three questions:

1.) Is your system overclocked in anyway?
2.) Which PCI-E slot did you install the 7850?
3.) What drivers are you running?

While a quality 400w should be fine for your rig, I can't speak for the quality of the unit you have. If your card is being underpowered, and this is a result of that possibility, I recommend refraining from any sort of gaming until you can upgrade your PSU. I am not entirely convinced it is your PSU that is causing this just yet though.

1. No its not overclocked
2. The one http://s18.postimage.org/rcjifaxgp/880_G_Extreme3.jpg
3. Latest AMD driver 12.10.

Download GPU-Z Here:

Under the "Sensors" tab, tick the buttons for "Continue refreshing this screen while GPU-Z is in the background" and "Log to file". Save the log file somewhere were you can easily access it, like the desktop.

After you have done this, run a game, and play for 5 minutes or so. When you exit the game, close out of GPUZ and upload the log file here.

Well, I don't see anything out of the ordinary in your log. It doesn't appear that your GPU is throttling, and your temps are pretty normal. Were you experiencing poor performance with this game as well while you were logging this data?

If you were experiencing poor fps in this session, it isn't evident in the log, which means you have something else going on besides GPU throttling, or overtemp issues.

Ok, the next thing we can try is pull up your resource monitor by hitting the start key and typing "Resource monitor" into the search field, and hit enter. Go to the CPU tab, and keep it there.

Play your game for a few minutes, or run Heaven for a few minutes to stress your machine, alt tab out of the game/heaven, or exit and take a screenshot of the CPU activity. If you can select the process for whichever game or utility your using when you make your screenshot, that would be helpful.

If for some reason your CPU is pegged at 100% throughout your gaming, there is a possibility that perhaps you have a CPU bottleneck. I would think that a 1055t would be more than sufficient for an HD7850 (or anything else for that matter), but it doesn't hurt to rule out all of the possibilities.
