re-downloaded and it seems it worked. running on it, no problems ecountered so far. http://valid.x86.fr/8z7cq9 2702 seemed a pretty solid performer, will reply if the new 2801 has problems.
I'l wait a couple of days to see if there are any problems and maybe then i'l upgrade. I didn't encounter any stability issues with 2702 so i don't see any reason to upgrade as no new features are added. Thank everyone for trying it out anyway.
I've updated my Bios to 2801, but i have problem with bclk frequency, in particular under load..
On x264 benchmark, Bus speed oscillates from 94.x Mhz to 99.x MHz. This causes cpu frequency goes back under 4.6GHz when it should be fixed at 4.8GHz. I reloaded bios default settings with no luck.
Going back to 2702 the issue is gone with bclk broadly stable at 99.9MHz.
