If 2133 speed ram has 11-11-11-30 timings at 1.6v does that mean you can run the RAM at a lower speed(like 1600 or 1866) at a lower voltage(1.5v)with tighter timings like 8-8-8-24?
Yes, basically. There are pretty much only 5 types of RAM, not the millions you see, made by 5 companies you've never heard of and then slapped with a different sticker, heatspreader and PCB - spektek and qnix(sic) (bad ram), PSC and BBSE Hypers (no longer made, only in 2gb sticks), micron d9, hynix, and samsung. Theres a few subtypes as well, samsung HYK0 (wonder ram) and HCH9 (better), Hynix CFR, MBr, BFR (different density chips, CFR is 'worse' is 'slower' but double sided at 4gb sticks, BFR is the hyper hig speed 3-4ghz sticks but being single sided at 4gb, perform worse about 400-500mhz wrose per clock, think of it like single channel vs dual channel).
Buying the right RAM means understanding what the stick is really made of. Saying something like 'i prefer gskill over corsair' is kind of misguided, neither company makes ram (and both have the same outstanding lifetime warranty and support, like all ram these days). A gskill hynix CFR is going to be exactly the same as a corsair hynix CFR.
RAM is often binned, but really only see that at 2800mhz+ kits. Sometikes the 1600-2133 are low bins, not always though.
So seeing as theres literally basically only a couple types of ram being sold, what happens is companies will sell the same RAM IC in 50 different ways. Literally. A prime example of this is PSC RAM of yesteryear, for example, gskill sells them as Gskill ECOs at 1600 CL11 1.3v, and then as Gskill Pi at 1.5v, and some 'premium' kits at 1.65v, yet its all the same. Then they have them as ripjaws, ripjaws x, z's, etc ad nauseum. Mushkin sold PSC as 1600 6-8-6 and 2200 7-10-8 in about 5 different lines, charging more for 'premium' redlines than 'midrange' black. this is true today still.
The stock ram speed ram is sold is really quite irrelevant, as the kits will do much more, just like CPUs and GPUs. So something thats 1600 CL9, will be sold as 1866 CL10, and 1600 CL11 1.5v, and 1600 CL10 1.65v. They are sold under a MILLION different combos. They may be some hynix that do 3ghz easy, or some microns that struggle to go past 1600.
Right now these best RAM to buy would be the Gskill Ripjaws X 2400 CL11-13-13-31 2x4GB for i think $72 on newegg right now (they were $56 a few months ago). Thats basically the same price as the cheapest RAM, but being Hynix CFR they can do about 3.2ghz easily (for reference, I've validated 3300mhz without trying and Im running 2800mhz CL12 24/7). But im not sure what ICs this ram is, could always be the next HCH9s or CFRs for cheap, but probably not.
DDR3 Ram runs really cool, and is good to run up to at least 1.9v on air in 2 sticks (stay under 80c, though 2 sticks @1.75v is about 40-50c max). Every IC is different, sammies dont like much more than 1.65v, hynix seems to be best around 1.7-1.8v, BBSE loves voltage. Whatever RAM you get, just do 1.75v and the best you can do from there really.Edited by Belial - 11/22/13 at 6:16pm
