Foxconn uses the same Aptio UEFI as ECS and Biostar, yet all three versions have different menus. Of these, Foxconn and ECS are most similar, yet Foxconn’s is more restrictive.
Memory voltage appears to work, yet it’s the sole item found on the Fox Control Center menu page.
The P67A-S’ Advanced menu controls clock speeds, multipliers, and core voltage. We were unable to get CPU voltage changes to have the desired effect, Host Clock controls would not work in a predictable manner, “Non-Turbo” ratio is locked at the core’s original setting, and “Turbo” multipliers above 43x would revert to 43x under load.
Since memory voltage of the previously-described menu appears to work, we were happy to see that all memory ratios of the 21.33x were also available along with primary memory timings. Hardcore overclockers need not apply.
Searching through Foxconn’s P67A-S main menus brought us to the DIV-2S settings, also seen on the competing ECS board. Unfortunately, any changes we attempted were rejected.
I'm just missing benchmarks like SATA/USB speeds etc. Please Tom's get those numbers for us!
1. SLI "support". Do not understand why end-user has to pay for mythical SLI "sertification" (all latest Intel chips support SLI by definition) and a SLI bridge coming with the board (at least 75% of end users would never need one). The bridge should come with NVIDIA cards (same as with AMD ones). Also, in x8/x8 PCIe configuration nearly all NVIDIA cards (exept for low-end ones) will loose at least 12% productivity - with top cards that is about $100 spent for nothing (AMD cards would not see that difference). So, If those cards are coming as SLI-"sertified" they have to be, in the worst case, equipped by NVIDIA NF200 chip (though, I would not recommend to by cards with this PCIe v.1.1 bridge). As even NVIDIA GF110 cards really need less than 1GB/s bandwidth (all other NVIDIA and AMD - less than 0.8GB/s)and secondary cards in SLI/CrossFire use no more than 1/4 of that, a normal PCIe v.2.0 switch (costing less than thrown away with x8/x8 SLI money) will nicely support three "Graphics only" x16 slots, fully-functional x8 slot and will provide bandwidth enough to support one PCIe v.2.0 x4 (or 4 x x1) slot(s)/device(s).
2. Do not understand the author euphoria of mass use of Marvell "SATA 6G" chips. The PCIe x1 chip might not be "SATA 6G" by definision, as it woud newer be able to provide more than 470GB/s (which is far from the standard 600GB/s) - so, I'd recommend to denote tham as 3G+ or 6G-. As it is shown in the upper section, there is enough bandwidth for real 6G solution (PCIe x8 LSISAS 2008 or x4 LSISAS 2004). Yes, will be a bit more expensive, but do not see the reason to have a palliative solutions on $200+ mobos.
