Sunfire, the chipset isnt holding him back at all. Im, and a lot of other people too, very pleased with the 790FX. If the motherboard (if that was what you meant after all) is holding him back, could be a possibility as Im facing a strange 'max' as well. However, it could be simply the max after all.

I set 1.475V in BIOS and got 14x252 as max speed stable, increasing Volts to even 1.55V didnt show any improvement. I dont have watercooling though, but decent cooling. TRUE with 130+ CFM fan. At current settings I dont get above 50C load.

It's just 'strange' to see the CPU being 24/7 stable at one point but one Mhz higher HTT with even 0.075V more it doesnt improve. Maybe I got the real max out of it but if I see those results with LN2 and 3.9~4Ghz Im not so sure if this is correct.

@ Aussie: Im pretty pleased with this moterboard indeed. I simply refuse to wait weeks for a replacement so Ill order a new one today or tomorrow. The question however is if I'd go with the same one (as it pleased me) or with DFI. If you read the above part Im unsure if I really got the max out of the CPU and DFI really give some surprises now and then with increasing OC-ability.

The thing what makes me doubt to go with DFI is that they release a lot of BIOS's, mainly beta, but after all 80% of all their BIOS's are crap and it's very rare there's a BIOS with all things fixed and maxed. You'll have to pick the BIOS that works best for you and sacrifices things you dont/hardly care about

Their 790FX board looks solid after some good BIOS's, but if you look at some older boards some of them still have problems but after a while DFI simply goes like "Well, we're sorry, we've got 8 new motherboards with newer chipsets and cant solve the problem of that board anymore, have a nice day". Though as I said, I dont think that will happen soon with their current board as it's simply a good chipset but still.

*sigh* choises choises.
