Wow.. I almost miss the days of my X58 system being the daily driver, got many years out of that thing. Though, its interesting to see how increasing the RAM speed only seems to affect the 'copy' aspect and doesn't do much for Read/Write..if anything it ends up about the same or lower! That's why i just used a good 1600MHz kit, tightened the timings (9-8-8-20 CR1) at 1.5v and left it alone! My X5670 happily did 4.4GHz on an AIO at 1.28vCore, only had my IMC clocked at about 2800MHz and got figures pretty close to all these posted ones, as the IMC was much more efficient it didn't have to be double the RAM speed, if i remember right you only 'need' it to be a tickle over 50% higher otherwise there's little benefit - getting it to 3800MHz just made things get really warm with little improvement! I ended up hitting about 4.6GHz if i wanted to push past 1.4v on the core but..nah. And the QPI/Vtt i always kept at 1.2v, not like i had exotic cooling (a big air cooler/AIO is hardly exotic, is it?) but yeah, it's long since been retired. I actually miss the 8086K i ended up with, i hit the silicon lottery jackpot with that one! (5.4GHz no AVX offset at 1.38v) And of course de-lidded it! But i think i need to do some investigating on my current system as these numbers have dropped quite a bit...they're also not that far off the Xeons in terms of raw numbers now are they? Though mine used to easily do nigh on 50GB/s on the RAM before all the Spectre/Meltdown crap, wonder how much it hit the speed on Ryzen with Specter V3?
