AMD Phenom II x4 840 and Sapphire Radeon 7770 OC Bottleneck

[nakzjamz456]

Hey guys I'm new here and this is my first post in this forum. My fps in Skyrim is too low compared to the benchmark videos on youtube and I always get stutters on Skyrim and BF3. Is my CPU bottlenecking my GPU? Should I overclock my CPU?

Specs:
AMD Phenom II x4 840 3.20ghz
4gb(2x2gb) Ram unganged
Sapphire Radeon 7770 OC Ghz Edition
Biostar N68S3B
500GB HDD(tried formatting and reinstalling Windows 7, no improvements)



I tried setting my BF3 settings to low and I still got horrible stutters.


Thanks in advance

Have you upgraded your drivers? also No way is the phenom a bottleneck to a 7770. you could be getting low fps due to the 7770 just no being that great of a card

 

[nakzjamz456]

Yep all drivers updated

 

[stantheman123]

Download msi afterburner check you gpu usage in games like battlefield 3 skyrim etc.

is your fps around this? http://www.tomshardware.com/reviews/radeon-hd-7770-7750-benchmark,3135-8.html

My min FPS is 23 and my max is 60

Resolution is 1366x768

sorry for the late reply

I run Skyrim at 1080P with everything at max settings and average at least 50 FPS on my 7770. Something is definitely wrong.

I would also recommend what stantheman123 said and download MSI afterburner and check your GPU usage. I would also look at your CPU usage by using HWinfo.

Your CPU should not bottleneck a 7770 at all.

 

[nakzjamz456]

Avg: 44.219 - Min: 0 - Max: 64

LOL that 0 is the stutter

 

[nakzjamz456]

GPU usage : 50-90 sometimes steady 70

Maybe its the 4gb of ram? That gpu should play bf3 on almost ultra with ur resolution, and skyrim on ultra. That phenom x4 seems to basically be a 955 BE without being black edition as the clock speed is the same, but the 840 is in the same "Propus" line as a athlon II x4, and has no l3 cache, but that shouldnt cause that kind of fps in games

 

[stantheman123]

You have 4gb of ram? my battlefield 3 stutters with 4gb. Try get a anthor stick of 4gb and see if it fixes it

 

[nakzjamz456]

yep i do have 4gb ram I'll add another 4gb when i have the money.

you think this RAM will work with my motherboard?

[stantheman123]

Should be fine.

 

[nakzjamz456]

Alrighty

 

[lazyboy947]

will not work, u need two 4gb sticks as ur current 4gb is 2x2 and there is only 2 slots for ram on ur board

I'm gonna buy two and replace the old ones

 

[lazyboy947]

ah was not mentioned lol ur all good lol

 

[nakzjamz456]

I got my two 4gb sticks and i tried skyrim and it still stutters but without the Hi-res dlc texture pack the stutter suddenly disappeared oh about BF3, I still have to download the 6gb update :/

The CPU is the bottleneck. Your video card has a good mid-range performance if you run games at 1920x1080 at medium settings. I can run BF3 at average of 50fps on medium settings but once the 64 player action starts to hit, it drops to a minium of 20fps. I am currently using a X3-720BE with 4th core unlock at 3.4Ghz and running an ATI 6850. I tried Crossfiring two 5770 and gotten a better average of 60fps but it still drops to a minimum of 20fps. On the other hand, my cousin who has a i5-3570k with ATI 5770 is able to get a minimum of 50fps on medium settings in BF3.

I doubt the extra 4gb will make a big difference.

 

[stantheman123]

No your no way bottlenecked. If you think you are overclock if your fps goes up quite a bit you were bottlenecked If not no bottleneck. However I'm 100% sure that cpu won't bottleneck a 7770 the 7770 is not a mid range card it's a low end gaming gpu. Mid range would be a 7850,gtx 660,

but ish says "Your CPU should not bottleneck a 7770 at all."

 

[stantheman123]

Your not being bottlenecked....

 

[bigj1985]

The lower the resolution the more CPU dependant games become. you are being limited by your CPU plain and simple. heck even with a 2600k I had to OC to 4ghz just to alleviate all CPU problems. And I'm playing at 1080p. You are being limited by your processor guaranteed

 

[nakzjamz456]

I managed to solve skyrim's stuttering. It's the Hi-res Texture Pack that makes me stutter.

 

[iceclock]

uninstall it and run non-hd textures
