Got the father's P6T SE to replace my EVGA SLI3 which is in repair, and though in the benches it's ever so slightly beyond the EVGA, overall it's a really nice board. The only problem I've come across has been the High TDP Turbo limit, which caps the overclock at 4GHz when using a BCLK less or equal to 200. E.g. I wanted to go for my beloved 186*22 and nope, it wouldn't stay at 22, dropping to 20. Cross-flashing to P6T WS Pro solved that issue but introduced more substantial ones, so I rolled back and stayed at 4 GHz with HT off, LLC off, and vCore on auto.
Other than that, here's some nice results I've got with a set of three Crucial Ballistix 4GB sticks on this board.
Daily driver, 1600 7-7-8-18 CR1, 1.54V in BIOS. Must be stable cause BF4 hasn't crashed a single time, while with the less stable memory setups it would crash very soon after entering an MP match.
I was pursuing 30 GB/s read and achieved it on this board. 2000 8-8-9-24 CR1, 1.62V or 1.64V set in BIOS. 3600 uncore, 4400 core, both were required to achieve the >= 30 GB/s read rate. Pretty sure it was stable, though I can't properly Prime this since the cooling is not adequate enough to handle 4400 core, even with HT off. AIDA64 Extreme cachemem benchmark ran just fine though.
