What RAM are you getting/bought for Ryzen

TeamGroup Dark Pro testing at 3466 using the F4d BIOS for Gigabyte K7. Promising so far, will try for 3600 if this proves to be stable.
 
3600 was a no go, although to be fair I didn't increase the voltage above 1.38. It booted to windows but rebooted shortly afterwards. 3466 is stable in P95 at 15-15-15-36, well stable for an hour before I stopped it.

New Gigabyte 1006 bios on the gaming 5 has my G Skills 3466C16 booting straight up at 3466 off the xmp profile. I couldn't even post at 3200 before.

Which RAM is this please? That's my preferred board choice. The RGB or the ripjaw?

Cheers

Well in my eagerness to swap, I forgot to do benchmarks on the TeamGroup (hynix) ram.

But I've managed to get my Ripjaw V 3600 booting into windows at 3466 18-18-18-38.

I'm sure with some tweaking I can get it to 3600.

Here's some AIDA64 speed tests.

Are you able to tighten those timings at all? I'm seeing significantly higher L1/L2 scores at 3466 / 15-15-15-36 - about 200GB/s higher.

I'm running at 3200 14-14-14-36, haven't benchmarked yet though. Might be able to improve on that further

What motherboard is it? I just tried 18-18-18-38 and am still quite a bit higher than you - although I'm on an R7 1700 that might explain it?

15-15-15-36 (Although CL is showing as 16, must be a BIOS bug)

Possibly, I'm using a Taichi with the R5 1600. What ram are you using? Do you change any other settings to get it stable at 3466?
 
I'm using the Team Group Dark Pro (3200), all I've done is voltage to 1.37v and timings as per above. Can't get 3600 stable at any voltage or timing, so I think this is the limit. Did try 14-14-14-35 but froze booting into windows.
 
I have just bought a Gigabyte X370 Gaming 5 and a 1700... looks like the G Skill RGB is pretty decent compatibility wise? And it looks cool :)

Do people think that the 3200 kit is sufficient or is the 3466 / 3600 worth the gamble on the hope that future BIOS will like it?

It will be 2x 8gb so hopefully ok...
 
The main thing about the RAM is you really want Samsung B-Die ICs to ensure a generally hassle free time. These can be found in 3200MHz CL14 kits and i believe 3600MHz CL16 kits or the high frequency kits. I believe the 4000MHz CL18 are Samsung B-Die too.

Hynix MFR ICs aren't too bad, my Corsair Vengeance LED 3200 can do 3200MHz CL14 with 2x8GB and a little work but 4x8GB is a struggle for 2933MHz. I can (and will faff) some more and i'm sure i'll get 3000MHz stable, but doubt i'll be able to get the same speed and timings as 2x8GB.

Edit:
Here's a useful list:

That's really helpful, thanks. I didn't notice until checking but the 3600 kit I had been looking at (£205) was CL17 vs. the £235 for CL16 kit (both B-die) or £165 for the CL16 3200.

I think going for 3600 is probably worth it for +£40 but not for +£70 (vs. 3200)

Any reason to worry about the CL17 position being too loose, or good to go?

Cheers!
 
I'm looking at this -

Manf.Code: F4-3600C17D-16GTZR

On the list there is no "R" on the end - does that make any difference?

The R will stand for RGB. The other kit is the non-RGB version. Same RAM otherwise it seems.
 
Cool, thanks. Turns out the 3200 stuff sold at other stores (OCUK don't seem to stock) is all E-die so glad you helped me out there - cheers! 3600 ordered :)
 
Worth noting that achieving 3200MHz-3400MHz has become much easier, but don't expect much more without some serious work.
