Gosh, those timings would generally be indicative of Hynix CFR, but could also be sporting the same ICs as your Team kit, MFR. Pricing (low) is what makes me suspect MFR.
This Team 2400 kit is the next one up in price and I know it to be single-sided MFR.
Plus there is no feedback on this kit...another indicator that it is a "new" kit. Many of the new kits are using the single sided MFR because (1) they have to do something with the ICs that don't meet the specs for the 2933 and 3000 kits, (2) memory IC availability is low right now, so Samsung and Hynix CFR aren't as available as they used to be which is what had been used for 2400 kits, which in turn (3) makes the 8 IC single-sided stick cheaper to make than one with 16 harder-to-get CFR ICs.
Edit #2: The only thing that doesn't support single-sided is the pic, as what I can see of the PCB just above the "golden fingers" isn't consistent with S/S modules. Look at your Team 2666 and on one side you will see a closely packed series of SMC just above the golden fingers and on the backside the PCB will be bare. The GSkill kit you linked doesn't look like that. Of course, I've bought kits from the Egg with pictures showing double-sided modules and received single-sided (Team Vulcan Series) so the picture may, or may not be accurate.Edited by Reefa_Madness - 6/6/13 at 1:29pm
