RYZEN Compatible - Cheap fast memory kits

Recommended Posts

so this thing is bugging me... my old i7-5930 is starting to feel it's age or I am, but i am seriously contemplating upgrading the mobo, cpu and ram, to 7nm. I have the 3950x in my microcenter cart along with the asus crosshair 8 but I am not seeing a good and cheap memory to go along with it at my Tustin store. I can also shop the egg and frys if need be but i'm looking for that seriously 7nm compatible mem that will make a new setup like this really amazing ! ... i'm thinking 64gigs and tight like 14cl ... what say you ?

If your running AMD X570 motherboard with Ryzen 3000 series processor, the Trident Z Neo F4-320014Q-64GTZN kit should work, I have used this kit on two builds with no issues. They are hard to find in stock, and kinda hard on the wallet at $600 for 4 x 16GB kit.  https://www.gskill.com/product/165/326/1562838710/F4-3200C14Q-64GTZNTrident-Z-NeoDDR4-3200MHz-CL14-14-14-34-1.35V64GB-(4x16GB)

Asus released new BIOS version 1502 a few days ago for Intel ROG boards, and didn't list any specific changes or improvements in update. I looked and can't find any white paper or listing of performance enhancements or patches/fixes,.. 

So I went ahead and flashed my boards #2 BIOS with it, and seems they did some huge memory performance updates. With manual memory settings I can run much lower VCCIO/SA voltage, and tighter timings @ 4000+ MHz running CR1 now.

You know I forget that memory comes in three designs, A0, A1 and A2. I keep forgetting to take that into account when overclocking and what slot to put it in.

On a side note, ASUS also released a new BIOS for the Crosshair 8 HERO. Just says stability fix. Maybe I can finally get 64GB to boot above 3400?

I have a nice 2x16GB 3733MHz 1.35V profile saved in 1502 BIOS, working on 4133MHz 1.4V CL17 2x16GB now.

Interesting update. I decided to pull off the heatsink on these Patriot Viper Steels 4400s (PVS16G440C9K). It is honestly not a heatsink at all and nothing is actually holding it on besides some tiger tape. Which isn't a good thermal pad either. I suggest putting a fan directly on or have good airflow.  It is a little disappointing but it makes sense why they are cheaper then any other Samsung-B Die binned kits by $70-100 lower.

Anyways the part number is K4A8G085WB-BCPB which translates to one of Samsung lowest B-DIE memory  bins of 2133 / 85c Temp. With a A2 PCB layout. So Patriot must be buying these is mass bulk for really cheap and hoping to get chips that can reach 4400. \

Make sense why I cannot get these to go much higher. But that same time, good job Patriot! Thanks for selling me really fast memory for cheap :)

This make me just want to watercool them. I have a block somewhere in a box. I wonder how high these would go when a bit cooler.

Edit: I was able to bring the timmings down to 14-16-13-13-27-40 :)

I manged to get 3800 14-16-13-27-40 1T @ 1.5v out of G.Skills 3200 CL4 F4-3200C14D-16GVR (Newegg link) . CL14 would error out near the end of Memtest86. I'm sure if I played around with the Trfc or CAD_BUS I could get it to pass, but I am lazy :)

Not bad for $100 ram.

I just reviewed G.Skill TridentZ Neo 3600 Kit.  Great memory kit if you don't want to play around with FCLK or memory overclocking. Even better if you do!
