Posted January 16, 201312 yr Hey Guys Nice section here, like it Finally i found time to test some new Samsung IC from G.SKILL, here are some screens. some quick tests from 2666C10 16GB kit Dec2012 Default 2666 C10 tight timing 1.65 Stock Air cooling ambient 23 degrees (HyperPi Stable) Max 2720 with 1.65 and Stock Air Cooling 2920 C10 loose secondary and third timings Cold Air ambient 10 degrees 2780 C9 tight timings and stock air cooling ambient 23 degress 8GB 2870 C9 tight 2V for this and cold air 10 degrees Note: Samsung is not like other ICs when colder they scale ,they stop scaling after 5/10 degrees and when they are too cold start to be very unstable, normal ambient 23 in my room and opened windows 10 degrees they scaled about 90/100MHz and very stable when they are load (HyperPi) no worries about voltages you can go over 1.95 on normal air and +2.0v when colder for benching.
January 16, 201312 yr Crew Best frequency to run these at during benching Hiwa ? 2600C9-12-12 ? +2800mhz and higher seems pointless as the looser tertiary timings don't make it much faster ( if not slower )
January 16, 201312 yr Author Higher freq is just show no performance there, 10 seonds slower when run 2933 loose s and t timings compare to 2666 tight s and t , nut not +2800 caz that 2860 C9 is with tight S&T , if memories can do it specially if cpu IMC is capable to run 16GB high freq memory so maybe a day can beat PSC (2% of CPUS?)

January 16, 201312 yr 1330-1360MHz with 9-12-12 is the region to aim for if you don't want to worry too much about RAM while benching, Alby.
January 16, 201312 yr Nice memories! I have here only 2400 CL10 TridentX, one set does ~ 2750, second 2800+, I have to test them more deeply and I will also post some info
January 29, 201312 yr Crew Nice memories! I have here only 2400 CL10 TridentX, one set does ~ 2750, second 2800+, I have to test them more deeply and I will also post some info I can only reach 2666 on mine mate, 2800MHz boots in OS, but reboots the PC as soon as I start to stress them... latest batch 2400C10 are great till 2600MHz; doing 10-12-12-30 1T at 1.73Vdimm, 2666MHz needs 11-12-12-30 at 1.75Vdimm...

February 17, 201312 yr so temperature wise, are you saying you cooled them to 10 degrees and that was about it? didnt try sub zero?
March 8, 201312 yr my TridentX 2666cl10 1400 9-12-12-21 /32m only 1,880v, with 1,9 i can run 32m but trrsr4:) Edited March 9, 201312 yr by nachtfalke
March 9, 201312 yr yep, imc it is very important with some latency.. i can also run 32M - Twtr set to 4 with this IMC ...and compared with another cpu´s imc ( that i tested) on this cpu i can run less v dimm , about 15mv less at same freq/latency
