Yes I know that, I have 8+2 phase UD5 and I can't make my 8350 stable at 4.8 GHz, all these boards can do 35 Ampere per phase, >280 Amperes for CPU only, can load >500watts CPU overclocking. But all these boards don't support LLC in BIOS. Without it you can't make your CPU vcore stable and you will not be able to push your VRM to its limit. I have tried setting vcore to 1.60 volts. You know what happens at load ? vcore goes to 1.456v, I set 1.80 volts and it went down to 1.50v, idle temp and voltage stayed horribly higher for 24/7 usage, same happens with most UD7 rev 1.0 owners. I also didn't know about this LLC thing when I was using 1055T. Same is happening with you too.
What? I ran my FX 8350 at 1.7v, 5.3ghz on all cores and it lasted like 3 minutes of IBT AVX burn test before it crashed. I run 5ghz flat 1.6v 24/7. I think you are a little confused, my UD5 has LLC support.
Also, F12 official BIOS came out on the 7th. Not sure why you're having these problems, you're probably just going multi-only overclock, which will usually only take you to 4.8ghz on any board. The big OCs come from a mix of bus and multi overclocking, and it takes a lot of time to dial it in because there are bus dead zones where the system is just much less stable when the bus it at a specific speed.
I've had bus/multi combos where it wasn't stable at 4.8ghz and then I've had bus/multi combos where it was stable 24/7 at nearly 5.1ghz. So you just need to play with it. FX is not shake and bake "woo I changed my multi and bumped vcore a little now I win benchmarks" chip, it's a chip that takes dedication and lots of tweaking to get right. That, and tons of reboots.
UD5 BIOS is fantastic with being able to save BIOS profiles, I suggest you save a few bus/multi combos and see where you can go with it.
But as for you guys talking up 4770k, I'd gladly pay $300 for a nicely binned FX chip. I've OCed SB and I've OCed FX and Intel OCing has become so simplistic with such little room to play with things that I would never brag about an Intel OC on SB or later.
But this seems about right for AMD, they've been pulling this crazy release price and then it gets sane in a few months thing at least since 7970. This is about where it should be, and if you're looking for a fun chip to play with and you're ready to graduate from "look at muh benchmarks I changed the multiplier and got the best OC possible xD" crowd then it's not a bad deal.
