No the reviewers claimed it wouldn't even post at 4.9GHZ much less 5. and Fullinfusion not only posted, but booted into windows and ran a benchmark successfully. Reviewers don't have chips long enough for 24/7 clock testing. If they were only able to hit 4.7 it might mean the 24/7 clocks of the chip were it's turbo speed and nothing more. seeing 24/7 400MHZ higher than turbo flies in the face of what they were claiming. At any rate I'm typing this from my i7 4790k rig right now. Ran a bench got 10580 in 3dmark 11. While that is 2000pts higher than my i7 950 and gtx 480 sli rig at stock, it's 1000pts lower than the max score. That will not do at all! Must get clocking. Batch number is L336D109 anyone have a chip from that batch?
