I just recently got a new motherboard (MSI z87 MPower Max) and an i5 4670S (yes, I'm aware, it doesn't OC and I got an OC board, it's a temporary CPU.) Full specs down below.
According to Prime95 my CPU speed is 3100.6mhz as expected, base multiplier is x31, but according to it the Turbo multiplier is x34, which is should be x38 (3.8ghz) as the spec sheets state. In the stress test and when rendering a 4k video I can only seem to get the CPU to peak at 3.38ghz.
I'm using a CoolerMaster Hyper T4 to cool this thing and it's well under 50C at most times even 10 minutes into the stess test, according to windows I'm only hitting a max frequency of 3.38ghz, which is a bit odd. I've enabled MSI's OC genie and now instead of reducing the multiplier below x31 like Intel CPU's it's now locked at 3.38ghz. Something in the motherboard or some setting is not reporting the right turbo multiplier, I've dug around and I'm stumped at this point, I obviously can't manually adjust the multiplier as it's a locked CPU, when adjusting the base clock even in the slightest the system does not boot.
Specs
CPU: Intel i5 4670S http://ark.intel.com/products/75049/Intel-Core-i5-4670S-Processor-6M-Cache-up-to-3_80-GHz
GPU: Gigabyte Geforce GTX 970
RAM: 6gb of some corsair 1600 XMS3
PSU: EVGA 600B 80Plus Bronze
Mobo: MSI Mpower Max Z87 Bios ver. 1.7 (I haven't updated to 1.9 yet because I don't really see the need to, but I might do so anyways.)
