Memory Ryzen RAM - what works @ what speed
- Thread starter LukeD
- Start date
Kingston ValueRAM 2x16GB DDR4-2133 ECC KVR21E15D8K2/32
Works perfectly at 2133.
OC: So far perfectly at 2400.
ECC is reporting as "6 (0x6) Multi-bit ECC". ( Gigabyte AB350N ITX ).
Will see in the future what the memory can handle beyond that but already happy. Spend 210 euro for the kit ( retails at 330 euro ) and OC to the 2400 version ( same DDR4-2400 kit retails at 400 euro ).

I bought these 3200 sticks from Newegg the other day, Team, who like to use Samsung B-die 
They are Sammy B, timings are 14-14-14-31

Used in my Silverstone SG13 Ryzen 1600 build which I've overclocked to 3.95 Ghz.

I did the update to P.3 on the ASROCK AB350 Gaming ITX/ac ..but now my Vengeange LPX will still not do the 3200 , and I lost the CL15 at 3066 ..it will only do auto now and that defaults to the looser 16-18-18-36-54 .

I'm a little late to the party but I might have some information someone will find useful. I recently put together a Ryzen 1500x system using the ASrock ab350 fatal1ty itx board.
I'm using G.Skill TridentZ dual-rank Samsung E-die ram (F4-3400C16D-16GTZ) which i got from a friend. I've read that dual-rank ram isn't great for Ryzen, but I think that information is outdated. This kit maybe rated for 3400 mhz but the XMP profile of the asrock board sets it to 3333 mhz with a cas latency of 16 and it does boot, however it was not fully stable.
I ended up going with 3200 mhz and 14-15-15-34 and also tightened some of the secondary timings as well which proved to speed up the cpu further. I had to use 1.45 volts for the ram to achieve these settings. and about 1.125 volts for the SOC. It is now fully stable.
I get a cinebench score of 914 when overclocked to 4ghz flat, which is very good for a Ryzen 1500x. Though that only tells half the story. According to many sources dual-rank ram is faster than single rank at the same clock and cas timing. I've seen several videos showing a higher in game FPS with dual-rank so long as the GPU isn't the bottleneck. I've read that dual-rank memory takes a little bit of the load off of the memory controller, perhaps that is part of the reason I don't know.
To add to this information I would like to explain also the importance of tightening secondary timings. When i did that i achieved higher physics scores in 3dmark. So i would recommend experimenting with that no matter what type of ram you have.
I found this video useful for overclocking secondary timings even though I don't have the motherboard he is using.

I have two 8GB single rank Samsung c-die from an HP OEM System. Using an 2400g and a gigabyte b350n itx board with the F22 Bios I was able to run them at 3400mhz cl 16 19 19 19 38 58 T1 with 1.4v and gear down mode enabled. The rest of the timings are mostly set manually. The only noteworthy one is tRCF at 545 since I can't get it any lower.
I'm realizing how useful Gear down mode is. Doesn't seem to cause a performance hit at all, especially when it enables a higher stable overclock when turned on. I would say only turn it on if you're having stability problems with a high memory overclock.
Running my F4-3400C16D-16GTZ dual-rank samsung e-die kit at 3333 mhz now 14-15-15-32 CR1 with gear down mode enabled (1.45 volts still).
