Frustrating bottleneck

post #1 of 112

Thread Starter 
Hello overclockers, I (just a few days ago) built a computer with these specs, with the intent of playing bf3 very smoothly maxed out with 64 players: 8gb ram, 650w psu, biostar a960g+, gtx 670, fx 4100 and an antec kühler h2o 620. Sadly the fx 4100 is severely bottlenecking my gtx 670. So here is my question: A: should I change my motherboard to intel and get a 2500k? which would be a pain because I just built this. B: wait for piledriver? C: Buy an amd fx 8150? I am looking for a future proof gaming machine that can run 64 players maxed. Thanks for your time.

I would have to say that for what you want, a switch to Intel might be in the right direction. I do not know how well that motherboard overclocks, but I cant imagine it being fantastical. The FX-4100 is an ok chip at its price, but it isnt meant for more CPU intensive type situations. A Deneb or Thuban is also a possibility. Sounds like you got a good GPU, but undershot on the CPU. Its all about finding that perfect balance between CPU and GPU thumb.gif

post some screen shots of your CPU useage during a game, as well as GPU useage.

Run like MSI afterburner and your task manager, then launch the game then after a bit of playing Alt TAB out and posta screen shot showing your useage of CPU and GPU

My you usage in 64 player combat is usually 32-45 percent and my CPU is 90-98 percent. I have fps drops to 0-11 fps every 2 minutes or so.

BF3 as i tested with my phenom x6 1055t uses all cores when gaming. better check your cpu usage when playing BF3. it should utilizes all of your four cores. screenshots would be helpful.

BF3 only uses 6 cores.

I recommend waiting for the FX-6300.

I would give the overclock another shot. 4.2 should be not problem at all. Are you on stock cooling? Try giving it a small voltage bump to stabilize it. While I do think you undershot your CPU choice, there is no reason to go intel, especially since you already have the motherboard. Download this http://www.xyberdyn.com/tools/ , play the game, then hit the windows key to take a screen shot of the monitor. Post it here along with your GPU usage using MSI Afterburner.

I am on antec kühler h2o 620 water cooling. Do you think 4.5ghz would be stable with an a960g+ motherboard? If so, why should I put the voltage at? My motherboard's max is 125 and it's max clock rate is 5.2 hyperlink transport speed.
