Will my FX-8350 bottleneck my 2Way SLI Asus GTX 680 DCU2 TOP ?
Elie_Stevens
Hello There, so, the question is simple. My specs are those ones ->
Chasis: NZXT Switch 810 Black
MoBo: MSI 970 Gaming
PSU: Nox Urano TX 850W
SDD: SanDisk SSD 128GB (Main)
HDD: 1x 1TB 1x500GB 1x320GB 1x200GB
CPU: AMD FX-8350 Black Edition
CPU Cooler: Cooler Master Hyper 412S
GPU: 2x ASUS GTX 680 DirectCU II TOP 2Gb GDDR5 2-Way-SLI
RAM: 16 GB = 4x4 Gb DDR3 2133MHz (Working at 1600Mhz with same timings, coz 2133 caused instability due to differents CAS.

ak47jar3d said:Yes, it should bottleneck in some cases. If really depends on what games you are playing.
I've overclocked it to 4.5Ghz, also overclocked GPU's to 1402Mhz and Memory Clock to 6105Mhz. Also running now 1866Mhz ram speed with correct timings.
Checking Stability at the moment. looks fine but, when i play games, GPU can go to 80-90% usage and CPU still at 25-40% usage. - Best answer

you will never reach 100% cpu in games that only use 1-4 cores, which is the vast majority.
Compounded by the weak single core performance.
You are also adding up the burden of running 2 cards at once on top. So yes the cpu is the bottleneck.
so the question becomes which games do you want to play specifically? -

Arma 3, H1Z1, BF3, CSGO, Dota 2, ARK, Skyrim and GTA V
I think this is the most common titles i play arround the week.
Also, i have another little problem and it's when i want to stress test GPU, it just doesn't works... It says the NVIDIA Kernel Mode Driver has stopped working and has recovered. This happens since i overclocked CPU and updated the RAM to 1866, checked timings and adjusted them, both are same and CAS 11. System is stable, i can game, play with SLI much better than before, but i just won't be able to run 3DMark or just Stress Test GPU with Aida64. Do you think this can be ram speed faulty ? Also, last night i changed the thermal paste of my both GTX680 since both were like stones instead of thermal paste rofl. Applied a new one, aftermarket one, Reduced the temperature in Load by 7-10º wich is really nice because the fans are running at much lower speed than before, because i had a custom fan settings due to the overheat, now they just in auto and not passing 80º on the top card, the other one, even on full load, it only hits 50º ^^
Thanks to both of you for your repplies, and awaiting a new one! -

Therefore your CPU will be bottlenecked
But this is an 8 Core at 4Ghz, stock, i don't get it, i've OC'd to 4.5Ghz stable anyway. Wich AMD Cpu should i get then ?
The FX 8350 won't bottleneck any sli/cross rigs. The FX 8350 will bottleneck only heavy single threaded games. The FX-9xxx series are nothing more than an overclocked FX 83xx.

thats a contradiction
that cpu will bottleneck all sli/cf setups when you actually need cpu power to run the game
or when the game uses less than 8 cores, which means it will bottleneck the vast majority of games -

arma, h1z1, ark, gta5 will all be cpu limited by your setup
dota2, csgo, skyrim (fully patched + tweaks ), bf3 should all be playable
