Basically in 3dmark Vantage I lose about 1000 3dmarks compared to a UD5 at same speeds and no amount of tweaking has made up for it yet. Sorry if this is a noobish question but I have not yet messed with any of the skew settings, does this affect performance of the board?
check the BR review on xcpus.com, they compared it to the classified and saw the same weird perf drops, it only seems to affect some memory dividers... it could be that you have to manually adjust the mch straps for the diferent memory dividers... i dont know why clock for clock the classified is slower, but i wouldnt be surprised if its caused by some relaxed timings they use to get higher bclock/qpi speeds? i dont know if you can actually adjust this and get back to tight timings and good clock per clock performance for people who really dont need high bclocks...

but the dram bandwidth is the about the same between dfi and evga .
mem skews that i am talking about is a internal setting in the bios
for dfi it is set via bootup clocks which are tweaked by their engineers
evga is via mch strap.

rtl 53 at 2050 c7 is really unreal and awesome dfi cannot do this atm with
their current bios afaik.
yeah i thought so too, but i dont think its turbo since it affects diferent mem speeds... some speeds are fine, some are notably slow

thats odd about dfi btw, are you saying they decide when to chose what strap and dont allow users to adjust it manually in bios? thats kinda weird for dfi...

but with lower memory multiplier and same uncore multiplier you can get higher? try more vtt and... i dont know how they are called on the evga board, but increase the x58 voltages, theres a 1.1 and a 1.5v voltage, increase both and see if it helps... can you get higher with cas8? i was quite surprised when raja showed how much memory can hold you back bclock wise... he switched from some good samsung to some good elpida sticks and it gave him 10mhz higher bclocks or even more iirc... and he couldnt get those even with relaxed timings before...

its weird, and i dont really get why... but several people had the same experience, they couldnt get high bclocks even with high vdimm, vtt and loose timings, then switched to another set of mem and could get noticably higher bclocks then...

whats the highest bclock you can boot at SAE?
your on phase change right?
