Posted June 3, 201312 yr So what are you guys doing to get these crazy frequencies? I'm using a kit of 2666C10 Samsungs and the highest I can get is 3000. Any ideas?
June 3, 201312 yr Samsung is not as good for raw frequency as Hynix (single-sided MFR in particular). Might be a cpufreq/IMC limit as well.
June 3, 201312 yr Author Samsung is not as good for raw frequency as Hynix (single-sided MFR in particular). Might be a cpufreq/IMC limit as well. I figured Hynix was the one setting the records. How high do you think Samsung will go with a good IMC?
June 3, 201312 yr Who cares how high it goes, it is good for competive 32M benching on air, almost as fast as cold PSC.
June 3, 201312 yr Ive seen some pics off 5M 56s on cold PSC ^^ early days but looking good Edited June 3, 201312 yr by Bullant

June 3, 201312 yr I care how high it goes! Half the fun with a new platform is pushing frequencies. :banana: then you need single sided MFR:)
June 3, 201312 yr Author Right. But I have Samsungs! And I want to push these. What kind of frequencies can you expect from Sammys with a good IMC? Are they going to stop around 3000 or should I be able to get 3200+ with the right timings/voltage?
June 3, 201312 yr Mine stop at 3100,no matter if 10-13-13 or 12-14-14,that is the limit at normal ambient.If you go sub-zero on them 3200+ is doable...
June 3, 201312 yr Author Good stuff. I can get a bit over 3000 but I'm not very experienced with pushing frequency on Samsungs. Thanks to l0ud, I can tighten the hell out of them at 2800, though
June 5, 201312 yr maybe help a tiny bit, you remember that setting we saw in early haswell memory OC leaks, tRDRD in GBT BIOS this is called tRRSR i find some increasing this it helps a few MHz(about 25-100mhz).
June 5, 201312 yr maybe help a tiny bit, you remember that setting we saw in early haswell memory OC leaks, tRDRD in GBT BIOS this is called tRRSR i find some increasing this it helps a few MHz(about 25-100mhz). 5 should be good up to 2800 and is much faster than 6, but you are right is should gain a bit for higher mhz runs.
June 5, 201312 yr Author I hate that all the secondary and tertiary timings are in a different order/have different names from the Z77 boards. As soon as I was getting the hang of it it all changes
December 15, 201311 yr test Samsung Chip on air single chanel http://valid.canardpc.com/8bgke7 RAM G.Skill F3-12800CL9D-4GBXL https://scontent-a.xx.fbcdn.net/hphotos-ash3/943278_651771651502939_1150165335_n.jpg
December 15, 201311 yr Do you have a picture of the ICs? I wonder what 1Gbit ICs they used, such that do 1500+ on air.
December 17, 201311 yr Do you have a picture of the ICs? I wonder what 1Gbit ICs they used, such that do 1500+ on air. I do not have a picture this ICs, this memory composed by dual side chips
January 2, 201411 yr I have a GSkill PI 1600MHz CL7 1.50v PSC kit, what is the maximum voltage that I can give the memories on air with good air flow?... maximum voltage for 24/7 and maximum voltage for bench.
January 3, 201411 yr ~1.75 for daily use and as long as they scale (up to 1.85-1.95V) for benching They scale very well, is a triple channel kit 3x2GB, I can get 2200MHz 8-11-8-24-74-1T @ 1.83v with 4500MHz and 43x uncore, they also do 2400MHz 10-17-17-36-88-1T @ 1.83v with 4500MHz and 43x uncore... let's see what I can do with 1.95v! Yesterday bought a second-hand GSkill PI 1600MHz CL6 2x2GB PSC kit with the same serial as my triple channel kit (11221040....), the idea is to make a 8GB kit with the 5 PI sticks without losing the ability to overclock them.
