[shaniwaketech]

OK ,THIS IS MY RIG.
ATHLON 2 X4 640 2.8GHZ QUAD CORE ,
4 GB DDR 3 RAM
600 WATT POWER SUPPLY ,
MSI RADEON HD 7850 2 GB DDR5 TWIN FROZR III

I GOT THIS CARD FROM CRAIGSLIST FOR 90 BUCKS,I USED TO HAVE A 9500GT WITH THIS RIG .BUT I UPGRADED THE PSU AND THE GRAPHICS BUT IT STARTED LAGGING ALOT IN GAMES LIKE GTA 4 AND AC3 ,,,,I DONT KNOW ,IS MY CPU BOTTLE NECKING THE CARD?

Additional Details
I'm getting 20 to 25 frames in Gta 4 and assassins creed 3 on low to medium setting but in crysis2 I get
Round 70 to 100 on hardcore settings? And sorry for shouting LOL

Yes, CPU bottleneck.

 

[shaniwaketech]

i have the ls ultra 600 watt psu? is that ok to handle the card?

Yuck Ultra D: even a 8 year old Enermax noistaker is better.

Just buy a cheap Phenom 2 x4/6 and overclock it to 3.5ghz or higher.

The Athlon 2 x4 should be OCable if your motherboard is OK.

Ultra is a crappy PSU brand but a 600W Ultra will probably be fine for a system that usually only needs a 400W unit.

7850 will be bottlenecked by the X4 640 most of the time, and in CPU heavy games, it will be very severely bottlenecked. It'll still get you a nice increase in framerates though, I think you'll be happy with it.

Nope OEM HP

Well, to be sure, what did you have before you got the 7850, and what kind of performance were you getting in AC3 and GTA4? You shouldn't see worse performance than before if it's a CPU bottleneck. If you were getting the same before or better than before then it's definitely a CPU bottleneck, but if it was playable before but bad now, then it's the GPU.

 

[Red Hawk]

Please do not type in all caps like that. Anyways, yes, that CPU will bottleneck your graphics card.

You got a really good deal on that card.

I had nvidia GeForce 9500gt and it did way better than my HD 7850

 

[shaniwaketech]

So is the card bad? Cause it works all right like no glitches but20 frames at1024x 768 in games for this class of gpu is very depressing

Not necessarily, but I would think that it's strange that a much weaker card would perform better overall. Perhaps someone with more experience in this could chime in. But now it's definitely something to look at. Did you use a driver cleaner when uninstalling the nVidia drivers? Did you install the correct drivers for your 7950?

yes, everything up to date ,i just installed fresh win 7 ultimate but no result

What's your PCI-E x16 bus operating at? Also try monitoring your 7850 clocks to see if they're not stuck in 2d mode while gaming.

 

[s44]

Have you tried running Afterburner or the like to see if you're running consistently at the proper 3D clocks/voltages?

 

[shaniwaketech]

i installed it but i cant see the voltage bar moving its there but nothings being reported by the card about voltage?

pcie-2.0

Play a game, see if the clocks and volts budge.

pcie-2.0

At x16? Not stuck a x1 or anything...

 

[shaniwaketech]

the fan gets real loud though.

yes its at x16 2.0

 

[shaniwaketech]

its vddc ? is 1.338 idk? on gpu z under load

More usefully, check to see what the history graphs say happened to these values if/when you see the framerate slowdowns you were talking about.

Yeah, the card might be throttling due to heat if the fans get real loud. Monitor the temp too when you get low framerates.

Performance less than 9500GT seems suspicious, so download and run GPU-Z, and submit for Validation (you don't need to use email). Post the validation link or code here so we can see it.
