Got your attention? Good, now I can finally rack up those imaginary "internet points" by showing off my geek bling.
So short story: the Xeon E5-1680V2 for the x79 is a 8 core cpu that is unlocked and sports a large jump in cache.
So as with any enthusiast hardware there is a time and place where users can build, overclock, and gloat over having a rig with the best hardware and unrivaled performance. This time is short as the next year the newest and greatest is released.
Comparing X79 to X99:
2. nvme support
3. 8 core cpu support
In the case of ddr4 I already have 64gb of 2133, thus the jump at this time to ddr4 doesn't really excite me. Nvme is interesting and may be enough to jump ship to x99 if performance for say load times simply went from fast to instant. Luckily it seems some people have had luck with the intel 750 pci as was my case. Great, so 1 and 2 irrelevant. 8 cores however is also exciting. However at the time I felt I was out of luck and 6 cores was just going to have to be enough (in all actuality its completely overkill... but its a free country). Still with google a short click away I decided to see if that magical "4970x" ever came to be. Toil as a did however for a while 2 hours at work I just couldn't find any hope until a few stories appeared.
Great! I just found 3 instances.... oh wait its just the same user on different forums arguing the same thing. A user named lutjens had obtained a E5-1680V2 and posed his results of a 4.5oc. It sounded too good to be true, especially that CPU-Z had some inconsistencies. Never the less the idea stuck. Did I ramble on enough yet? Well good, I'll keep going.
So a few days later at work I find said xeon in an ebay listing. Expensive... but still less than a 5960x. "Well if the intel 750 worked... maybe this will too!". With that I bought the cpu and cried as I submitted the payment. Just waiting for the cpu caused enough anxiety, did I just waste a big wad of cash? Well even if it did work the answer could be yes if you think about it.
Well as you guessed yes, it did work. With days of tinkering I present my 8 core xeon on x79 running at 4.4ghz. I just say my office has been quite toasting the last few days benching but at 1.352vcore at max load I couldn't be happier. Well the goal was to match my 4.5 4930k... but nevertheless I'll take it.
So if you really wanted an 8 core overclocked cpu on x79, try the E5-1680V2. From what I gather the cpu was for Apple's mac pros for late 2013. Most Xeons are locked since x58 however apparently doesn't apply to one socket configurations... yet.
Special thanks to lutjens for being heckled in forums but pointing me in the right direction.
