Solved Weirdly Low FPS but 20% GPU

[trowieuk]

Not sure why my AMD Radeon HD 7750 Xfx Core Edition isn't performing as it should, Trying to play Vindictus Europe. The system requirements are extremely low, my GPU exceeds the recommended requirement by 73%.. I should be hitting atleast 70FPS on high and 90FPS on low, but im getting 20-30FPS on low with only 20% GPU usage, it's not just vindictus it's other games too so we can rule that out. The GPU hasn't been overclocked either. Any idea's whats wrong?

download msi afterburner and see what your clock speeds are at. and while you're at it tick the default speeds box. should solve the issue. chances are your card was bundled with a 3rd party oc app and thats causing the issues.

Thanks for getting back to me!

The clock speed is at 667MHz - I haven't done any OC, wouldn't see a noticable improvement on my GPU. What default speed box? Everything in AB is at default except for the fan curve.

The core clock should be at 800 MHz and the memory clock at 1125 MHz. Keep in mind, the 7700 series will downclock to save power during times of low demand. My 7770 runs at 300 MHz when it has no load, but goes up to 1 GHz under load. That's normal to see a lower core clock. You need to run an afterburner test and see if the core clock goes up to 800 MHz.

Core clock is at 800MHz but the memory clock only goes up to 870MHz. When I run NovaBench the GPU usage goes to 90-100% and it does go up to 800MHz.

in MSI after burner try setting the clock and memory speeds manually to what they should be at default, and see if this helps.

HAve you got the latest AMD driver?

They are at default 800MHz and 667MHz, I haven't OC.

 

[badger906]

but the memory clock should be 1125mhz, set it to that and see.

The memory clock doesn't go above 870... see

The memory clock is supposed to be at 1125 MHz, that's not an OC. That's the speed it's supposed to be at. Your card isn't running at the right memory speed.

EDIT:
Just saw your screen shot. Something isn't right here. What's the exact model of your graphics card? Are you sure it's a Core Edition?

How old is the computer, and the card?

Those are settings it's always been on..

Radeon HD 7750 XFX Core Edition

I've had it for 2 weeks

Can you open Catalyst Control Center and look at the Graphics Overdrive tab?

Like this?



Take a screen shot and post it, please?

Mine doesn't look like yours, I have the 14.1 beta installed I think thats the new UI?

 

[Mellon Head]

Well, it looks like your RAM clock is set at 667, which I don't really understand. The card is not performing at spec. What is your power profile set to? Is it high performance? Maybe that will make a difference.

You shouldn't have to manually set the memory clock speed.

This is weird.

Power profile is set to high performance. Why would my RAM clock be showing in AMD and MSI and not GPU Memory clock? Obviously something is wrong and thats why im getting really low FPS with no GPU usage. I've been looking online for hours, I've run chkdsk no errors, re-seated hdd, ram sticks, gpu, psu, fresh windows 7 install, used tweaking.com, I've tried all the basic stuff and don't know what else to try

 

[trowieuk]

This is whats showing in Device Manager "PCI\VEN_1002&DEV_683F&SUBSYS_32481682" Do you know if that tells you model etc?

 

[trowieuk]

would a benchmark and screenshot of gpu info help?

 

[trowieuk]

Re-seated GPU and on the back it has a label which says ...

Core Radeon 7750 800M 2GB D3
FX-775A-CQ
FX-775A-CQF V4.0

and looks like the one here XFX Core Edition Radeon HD 7750 2GB DDR3 PCI Express 3.0 Graphics Card FX-775A-CGFR - Best Buy

So that confirms it's core edition right? New to GPU's so don't know whats right or wrong, but I know 20% usage on low fps isn't normal.
