Looking for some 16Gb Single rank dies, possibly for 4 x 16Gb or 2 x 32Gb Dimms.
Is there a way to tell for certain which Crucial Ballistix memory are using the newer rev.b?
Would all 32Gb Dimms at 3600MT/s or the Ballistix Max be running dual rank?
I know it sounds like overkill but I'm exploring upgrade options.
I don't think you can, those are mixed with 8Gbit RevE/16Gbit RevB.
I bought some patriot 16GB*2 Kit 4400c18, for the price of the kit, it is very likely it's single rank.
I will report back when I receive those from amazon next week(if I remember).
but why insist Single rank?
For your case if you wanted 64GB ram for whatever reason, you'd better off buying 32GB*2 RAM.
Reason: you buy 4*16GB stick, if you lucky enough getting all 16Gbit RevB, on a dual channel platform running 2DPC, you will still have a dual rank effective memory.
if you buy 32GB*2 sticks, they are dual channel anyway, save you trouble if you got both revE or revB
Isn’t there a chance you’d end up with 4 x 8Gb dies, it being quad ranked? I’m not 100% sure how it works.
yes.
chance 1: 8GBit IC for both pack
chance 2: 8GBit IC for 1 pack, 16Gbit IC for another
chance 3:16GBit IC for 1 pack, 8Gbit IC for another
chance 4: 16GBit IC for both pack.
chance for OC (or chance to even run stock stable):
chance 1: too many IC make OC impossible
chance 2&3, mixed chip make it impossible
chance 4: The OC capability effectively works like 2*32G, maybe ever slightly better..
That's why I don't recommend you do 16G*4.
because there is literally 1 situation you will have if you buy 32G*2 >> you get 16Gbit chip in dual rank.
What I mean is, 2 * 32Gb can still be quadranked 8gb IC, which would be bad.
@ATangk: It could be, but the chance is not huge at all, since crucial only rebranded their Ballistix lineup like few months ago which is after 16Gbit IC went mass production.
What's the odd for they to make a extremely complex PCB, solder on so much 8Gbit IC, and also making sure all the chip together runs high speed?
I'd go 32GB*2 still, even if I'd end up with that small chance of getting 8Gbit IC.
@ATangk: Big Oof
I guess if this is the case, buy two of 16G*2 kit from Amazon, before installing them just have a peek at the PCB to make sure if they are the same.
if not Amazon's return was generally not too bad.
Or go to a retail store and ask them nicely about your situation.
@ATangk: Hmmm, I only bought this
I've got the 4400 18-26-26-46 1.45V (which is now out of stock)
after I report back, you may want to consider get yourself the 4133 version. (4266 TRCD too high, and high voltage too)
but just to head you up, back in when I work at a computer store, patriot has insane failure rate, I am buying this kit for the lolz since it's stupid cheap.
If it works I win, it it doesn't I will simply return and keep using my old B-Dies.
@OMGJL: I saw that but those timings look quite bad… I guess in the meantime 32Gb should hold the fort. I swapped my cooler and now I actually have to remove it to replace the RAM, so I'm not super keen to have to do that a lot.
@ATangk: The 4133 timing is decent enough. 18-22-22-42; Voltage: 1.4V
I got the 4400 because it's cheaper than 4133 at the time of purchase, and high frequency MIGHT be better bins, even with way loose trcd.
Not sure how much luck you will have overclocking large dimm`s. I moved from 2x16gb, to 2x32gb, and briefly tested with all 4 sticks (so 96gb). Generally the larger the ram count, the further I had to reduce clocks to pass memtest.
That said I don't know a lot about b-die and other nuanced details. I didn`t want to spend days squeezing out the extra memory performance
Wouldn't mind knowing also.
