Yeah they are stable man!!! I have new 32m kit GSKILL PSC 2700 6-9-6-21 1T TRFC like 60 and all thirds tight.I found them this weekend. More submissions to come with those. These are the same PSC will not take as much volts as my new best though.
Whats the 5ghz Boot in on that chip on air???
I did 6.475 ish ghz in the Corsair Comp at Computex with my retail. My run was with 1.65v ish too and -100. We did not test more because of time pressures. 6.45 was 1024. Again maybe more is possible.
