hey guys
just received a couple kits of the latest sandy bridge gear from gskill, these kits are targeted at working specifically with sandy bridge..
sandy is a bit of a different ram clocker than we are used to with X58 and especially Lynnfield.. as we are locked to small BCLK changed there is not a huge amount of room to move up and down with our overclocking...
for example on the 2133 ratio you can go from about 1035MHz with low BCLK to about 1111MHz with 105ish BCLK, hopefully in the future we will see more BCLK options to really open up these kits... you wont see any 2400 MHz style ram clocks yet..
that being said, the bandwidth on sandy bridge is very impressive and we dont really require that huge ram frequency to get some very efficiency performance...
i found especially when running 16GB density i could of used some more BCLK, finding a combination that worked well with it was quite difficult and this at the moment is a sandy bridge limitation instead of a kit limitation.. if you look at the results from Hiwa on 1156 you can see 2200 MHz LINX with high density..
i will have some 1156 results to follow in the coming days..

Performance
Lets jump straight into performance and see what these kits are capable of..
Looking at the 4GB 2x2GB kit first...
LINX @ 1096MHz 7-9-7-24
Everest bandwidth @ 1107MHz 7-9-7-24
LINX @ 969MHz 6-8-6-24
Everest bandwidth @ 969MHz 6-8-6-24
Now some figures on the 8GB 4x2GB kit
LINX @ 1112MHz 9-11-9-28 1T
SuperPI @ 1107MHz 9-10-9-24 1T
Everest bandwidth @ 1107MHz 9-10-9-24 1T
LINX @ 969MHz 8-9-8-24 1T
Lastly figures of 16GB 4x4GB performance
Everest @ 1050 9-11-9-24 2T
LINX @ 969 8-9-8-24 2T
