Falc0nPuls3 didn't start this thread to brag about his GPU but it appears that's the only reason you chimed in. BOOOOO
Even at 5ghz I bottleneck on the CPU in strategy games with my OLD GTX460. Even an i7-4770K@5ghz will be the source of minimum FPS caused by CPU bottlenecks in lots of strategy games and MMOs REGARDLESS of GPU choice (except something iGPU class like a GT610). This has been heavily tested and explored by enthusiast players who have tried all sorts of things to "solve" minimum FPS issues in high unit count mufti-player games. Changing graphical settings, resolutions, and GPU strength doesn't solve it. It's tied to CPU performance, and usually per-thread performance, an area that PD needs all the help it can get.
If I had an FX-8320 and a GTX650Ti Boost and I intended to play games, I would overclock the piss out of that CPU to bring up my minimum FPS and maintain real-time in strategy games better.
Cinebench can not be used as a stress test for piledriver (except to test the FPUs, but it won't tell you much about stability or thermal limits under any other normal workloads). That type of FPU workload is bottle-necked by the schedulers really bad so you'll never achieve any sort of high workload saturation. I can run near 5.4ghz in cinebench, but that same speed will cause immediate thermal instability and/or shut-downs in other workloads. To be honest I don't even like P95 as I find it doesn't achieve peak saturation either. For performance tuning and stability testing I always resort to compiling and trans-coding, as those workloads achieve extraordinarily high saturation levels and will typically offer the fastest insight into whether or not a PD chip has enough cooling, and whether or not it is stable.
The reason for your throttling is CPU temps:
You're bumping up against the 70C mark on core temps, which is probably causing the throttling. The motherboard is fine, the CPU is fine... That particular little liquid loop is not a particularly strong performer, though I suspect that's due to the lower RPM fan it comes with. A quick lookup of how it stacks up seems to indicate that it is worse than many traditional 120mm heat-pipe towers, which means, not much better than the stock AMD cooler.
To get more umph out of the zalman, consider configuring your case fans to all blow into the case, and the radiator to exhaust so that all of the case fans are effectively "assisting" the radiator fan. I would also recommend using a stronger 2500+rpm fan on the radiator as that seems to be one of the biggest sources of performance variation among 120mm radiators. The cheap 120V that I have performs really well, but probably because it came with a strong performing fan.
Hmmm... Maybe a AFC1212D-PWM (Not sure if these work well on rads or not but 110+CFM! yikes! FUN!)Edited by mdocod - 4/6/14 at 1:19pm
