Tested some DDR4 Hynix kits recently: Team Elite 2400C16 HyperX Predator 2666C13 HyperX Predator 2800C14
DDR4-3200 multi works fine on nearly all X99 boards out there. DDR4-2800, -2933 and -3000, however, only seem to work fine(-ish) with ASUS.
This kit is most likely Samsung-based and should easily do specs of similar 2133 9-11-11 and 2400 10-12-12 rated kits.
Anything that reliably does 1400MHz 9-12-12-21 tWCL6 tRFC112-128 at or below 2.00V qualifies as "good" in my book.Depends on many things. 2200C7 are known to tremendously vary in quality, from kits that barely run 1200MHz to kits that can do 1333MHz 8-12-8 tight at 1.80V. $60-150 would be the range, but you're not likely to sell the kit for more than 100€ ($115) unless you show 1300-1333MHz 8-12-8 tight at acceptable voltage.Hypers are useful on 775 (X38 and X48), AM3,...
I'm not sure if you can or will ever be able to find good Samsung 2Gbit D-die on new kits anymore. Both 2400C9 and 2600C10 versions of TridentX are no longer available in both EU and US (unless you find an obscure shop that kept them in stock) and there is no other maker/model where you are guaranteed to get the same IC.So the only way to go is second hand market. Here is a 2400C9 quad set on ebay, for example: http://item.ebay.com/181652887869If someone is not willing to...
Best DDR4 for benching is currently Hynix-based.
Some Samsung DDR4 "tight" 1600MHz runs on air:
One of the most common issues about running "new" RAM on "old" Platforms is that new RAM is usually made with high-density chips that require high timings (tRFC in particular) which the old platforms are not able to default to. Could you go to BIOS - Ai Tweaker - DRAM Timing Control page and tell the sixth number that appears in the "1st Information" line ? (for example, it's 60 on this picture) If you see a value significantly below 200 then you could try setting the...
1) All DDR3 that are currently on the market are flashed with a number of JEDEC profiles (with generally safe settings like DDR3-1333 CL9 or DDR3-1600 CL11) purely for the purpose of backwards compatibility. To get anything above those JEDEC values, you either have to load the XMP (the "profile" with kit's specs) or dial the settings in by hand. 2) It is common that memory voltage readout on ASUS Z97 boards exceeds set value by 0.02-0.03V. 3) I see no reason to change...
You can probably get your set to run DDR3-1866 at 8-9-9-27 around 1.65V (which is perfectly safe) or at 9-9-9-27 at 1.50V or less. All you need to do is go into the BIOS and adjust memory frequency, timings and voltage.
