FX-6100 GPU Feeding

post #1 of 11
Thread Starter 
Will my FX-6100@4.0Ghz be able to run an NVIDIA 680 without bottlenecking it?
post #2 of 11
Yes it will bottleneck it. Check here and you see degraded performance on two 6950s which I would guess is roughly the same in performance to a 680.

If you get a good overclock on it it will still probably bottleneck a little bit, but it wouldn't be that big of a deal. It might be like getting 95 fps instead of 100 or something you know.

I plan to upgrade the CPU soon. Would like an Intel, but will probably get an 8350 so that I don't have to upgrade the mobo too.

Your current 4.0Ghz might not be good enough to feed the 680.
Try reaching for at least 4.4 Ghz stable, that will lower the bottleneck to just a few fps just as Dopamin3 said.
Lets say an i5 2500k with a GTX680 gets 100 fps, your FX6100 at 4.5Ghz will get 95 fps.

You have a high end board so getting to 4.4 ghz should be easy, maybe 1.47 vcore can do it.

If I push any past 4.0 with my board, my VRMs would get too hot. The phase is only 4+1 on my board.. :/

it says asrock 990fx in your signature. You should create a new rig in your signature and put all your parts in there so people can help you faster.

Anyway a 4+1 phase should handle 4.2 Ghz safely if you provide some cooling.
A small fan or these will do great http://www.enzotechnology.com/mos-c1.htm

You can either buy the gtx680 now and save up for an fx8350 in case you experience some bottlenecking,
or buy a gtx670 / hd7950 and save some cash.

I wouldve thought asrock's version of 990fx will have at least 6+2

Still it looks sturdy and should handle 4.2 ghz at least.
Have you tried touching those black mosfet heatsinks while 4ghz is at full load with prime95?
its the best way to determine if you're safe to go further.

If its just warm, you can overclock a bit more. If you cant keep your finger on it longer than 3 seconds, its too hot

Lol, it's all good! The Extreme 4 version has a better power phase and I'll try!

I have it up to 4.2 and stable
