I ordered an E5-1650 V2
so I'll report back once I get everything assembled on the bench.
I think this is a really good topic to be honest because IMHO the ONLY REASON I am still running on this X5470 (with (2)980Ti's on blocks) is because intel has rested on their laurels for about 8 years (or we're simply screwed and CPUs will never get significantly faster.. think that new 5.1Ghz Xeon is B$??
). When X79 lauched it was crazy expensive and the lame X99 is making it easier to get into X79
As far as my
experience with S775, my Xeon X5470 was a night/day difference
with regard to overclocking ability compared to my previous Q6600, Q9550 and QX9770 CPUs
in the same motherboard using the same ram. The X5470 has a 10x multi stock which means it is practically
an unlocked CPU so no an X5470 isn't 100% unlocked
but with a 10x..who cares
All I could get out of my QX9770 was 4.2Ghz no matter what (maybe it was a dud.. I don't know..) and with the X5470 I'm getting almost 4.6Ghz. Same exact system and components just a CPU change. I haven't run out of O/C headroom either yet my temps are just too high to go further. In addition (surprisingly) I was able to run my memory
at higher speeds with the Xeon X5470 than I could with the QX9770 (I am not sure why, these CPUs do NOT have an integrated memory controller). I'll include some screenshots for those who remember S775, I'm pretty proud of this one (and yes I'm using 4 sticks of ram).If you are familiar with the 775's and especially the 790i Ultra chipset you can agree this is no easy task. Look at the memory latency, top of the pack beating CPUs that DO have an integrated memory controller. My Xeon X5470 (Click to show)

Not too shabby
the Xeons are going to be higher bins and for that reason alone better overclocking is possible. It is also silicon lottery of course. When you get a Xeon that has an unlocked Multi, I would consider that the "Holy grail" of CPUs
... I really can't say from personal experience as I've only owned one Xeon but my results seem to be on par with what others also get. I really don't think I was all that "lucky" I just took the time to tweak. I am just one person but I think if running a Xeon was just completely pointless there wouldn't be nearly as much buzz about doing it as there is.. It is definitely possible, people are doing it and for socket 775 is was HANDS DOWN the best choice to run on that platform. The QX9770 doesn't even come close.
I'm betting on another round of Xeon success with S2011! Good times! We shall see!
