The first kit is a retail kit I picked up from Newegg in July. I did not have high hopes for this kit but it turned out to be pretty nice. I used this during Keep’s competition on a XI Apex and 9900k, and got it 32m stable at 4300cl13-13-28 1t which you can see here: https://hwbot.org/submission/4564122
Turns out this kit does pretty well but does require higher vdimm, testing on z490 with a 10900k, this took around 2.05 to 2.1 to get 4800cl14 stable. With some additional tweaking it very likely could do 4800cl14-13, which I tested for awhile but could not get quite stable. With more time or a better imc its very likely. Below is a SS with this kit after testing, test was for minimum passing.
Asking $250 $200, obo shipped for this kit based on the 1t performance, comes in retail packaging.
Team Group 4500cl18
This next kit is a Team Group Xtreem 8-pack that Websmile originally did a quick test on,
This kit would not post 4800cl14 1t for anything but does really well at 2t. At 2t it flew through 4800cl14-13 very tight subs at 2.05 vdimm. This was a very easy to use kit once you set vdimm right.
You can see despite no 1t on this kit the timings are nice and nets a good gb3 score even at 5ghz.
Asking $225 $180, obo, shipped for this kit, originally paid significantly more for it, but it wont do 1t on z490 like the other kit.
z490 Apex XII
I received this XII Apex from an RMA for a XI Apex since Asus couldn't repair the board. Board works really well, tested the memory kits below on this board. Comes in retail box, with all accessories, and RMA slip documenting the exchange.
Asking $375 shipped in the US, international shipping is extra.
This is a retail 10900kf, sp 65, that I bought to compare to my current 10900k. Some quick testing showed it was not as strong so I stopped testing it. Took core up to 5.2 in my quick test, imc is totally untested. Comes in clam shell.
asking $500 shipped in the US, international is extra.
~~4000cl16 Dual Rank Royals
Just finished testing this kit, ran up to 4700cl14 with pretty tight subs, I did not tune terts at all. It did not want to do 4800cl14 easily but could be possible with some extra time. Screenshots included show 4700cl14 and 4666cl14 which this kit managed with very low volts.~~
~~Asking $335 $320 shipped CONUS, extra for international. Comes in original packaging.~~ Sold elsewhere.
