MA790X / MA790XT-UD4P 790X bugs fixes etc etc.....

We both know this board was designed for 1666 and tight timing ram. We also know ram speed makes very little performance difference unless your benching and even then not much. Plus this is a 84.00 cpu and 80.00 motherboard so there we have it. Not really a fair comparison.

Not designed for 1666 and tight timing ram huh? Timings dont have any effect on the board as far as clocks, only the IMC. 1666 CAS 9 and CAS 5 are the same on the board. (1600+ cas 5 is good stuff )
I told you my 565 sample does 1800+ didnt I? The 555 isn't much different.

My 965 did 1790 with Hypers on my 890GX-UD3H, that clocks ram about the same as the UD4P so I'd like to see at least 1700.

While PSC can do 2000-2100 stable on 890FX Hyper won't even get past 1900...on 790 series that goes 1800-1880 PSC to 1700-1800 with Hypers...so it should be easier for you to clock PSC than I'm able to clock Hyper. When that board debuted, it was $130 and not $80 btw, I owned the DDR2 variant till I sold it to gomeler (he got 6 Ghz on a Sempron 140 with it) and loved it to death.
