Bought this cpu from here :
http://forum.hwbot.org/showthread.php?t=173585
Copy-paste from Firekiller's listing :
" It can do around 6.78-6.79 XTU, its also the 2nd highest clocking 7700K on X265 and can run Unigine at 6960+ MHz
Cache-wise it can do 6.5GHz easily "
Very strong IMC - on Apex IX, ambient, easily 4133 -12-11, SPI32m.
Under LN2, Stavros pushed the memories to 4200 - 12-12, with 0nly 2.04V.
What I can verify, is that under ambient water the cpu is good for 5.4ghz cbr15,
with only 1.32V on Apex IX, and 5.5ghz core / 4.7ghz cache 1.44V
