Ryzen and memory

[chew*]

I have ordered samsung B die. Rumour has it 2400 is realistic. I grabbed a 3200 c14 bin so worst case can tighten them up @ lower.

Any other types of high performance ic's the AMD crowd wants to see tested.

Seems 8 gig sticks are the norm now so for real worlds sake lets stick to 2x8g reccomendations.

Lets also stick to 2400-3200 speeds. Please dont ask me to test garbage however( cl 15-17-17 2666 for example )....something that does cl10 @2400 to cl14 @3200 should suffice.
Obviously got sammy b die covered already...

Oh and lets try to keep price sub $200. We are amd guys so lets be cheap about it..

Lmk now so i can order it.

I heard about 2933 Mhz OC is working also

[chew*]

Ive heard rumours but ehh is what it is could be screenshot stable. Thats why im going to see for myself.

2400 to 3200 according to rumor so thats the ballpark i will play in for ordering. Can always clock the 3200 14-14-14 stuff much higher but pointless if sacrificing timings.

Main importance is testing diff ics. Would not be first time AMD was not fond of a certain ic.

Any idea what ics these are?

V5.20 if can believe picture...

Ok i think v5.2x is hynix...

[FlanK3r]

I dont know, its possible. I have few kits ready: Savages, Vengeance and few TridentsZ So Im hope, one of them will be working with Ryzen.

I got some Samsung B-Die myself (Corsair Vengeance LPX DDR4-3733 CL17). I was unaware that Corsair was using Hynix anything in their Dominator series, but it looks like I've learned something new today.

[chew*]

The key is variety. Only a variety of samsung in different speeds wont cut it.

Not many options it seems though. Guess last one to look into is crucial. They use micron only.

These suck timings in with voltage it seems.

[Charles Wirth]

I am sure a lot of the reviewers will have many DDR4 kits handy.

The better ones from DDR4:
Samsung B, C, and D die
Hynix AFR and MFR

I'm quite sure they will but AMD and memory and total system performance has always been my specialty.

[drmrlordx]

I hadn't heard of Samsung C-die. Learned something new again! What a thread.

So is C-die generally better/worse than B-die?

[Charles Wirth]

C die is usually 4GB single side module and tRCD and tRP must be set higher than B die values.

[chinook]

I've ordered this kit (don't judge..)

https://www.newegg.com/Product/Produ...82E16820232485

Along with the voltron VI hero and a 1700X. If it's ok with you, chew, I'll post my results in this thread. I don't know what ics these have, though.

P.S. nice to have you back, chew

Nah dude I think you'll be alright, you can control the led's with i2c it looks like, or eeprom.
And besides those kits are usually among the best anyways, along with corsair platinums.
You're pretty much guaranteed to get a decent ic regardless with those.

I didn't realize that MFR was still going around, I knew they were still around 1st gen of ddr4 but wth...
I would think samsung is the safe bet, the hynix being a potential iffy, it should work but who knows yet.
If there is any ddr4 micron it may be worth a shot.

I always look for the gskill/corsair trident/platinum series 1st, then mushkin (red/black whatever it was called) and teamgroup, etc.
Edit: oh and Adata..., I like them sometimes (I actually prefer them and gskill the most).

I wish there was a src for oem these days wth...
That was always so much better, getting a few sticks at a time or whatever you could and binning them.
Cheaper and plain better I think...

C die is usually 4GB single side module and tRCD and tRP must be set higher than B die values.

Okay, sounds a lot like E-die.

In other (related) news it looks like B-die is playing well with the C6H at least. Word on the street is the C6H is achieving speeds of DDR4-3200 while other boards are not doing as well, except maybe the top-end Gigabyte one?

UEFI/microcode updates in the next few months may improve the situation.

[chew*]

The gigabyte is more than happy with the kit i initially posted/ordered 14-14-14 pc 3200. No tinkering required.

Asus is wrong.

[chinook]

Asus is wrong.

What do you mean by that?

[chew*]

Thats where the info came from...read news post...in one of the amd threads.

[chinook]

Got it now, thanks. Was worried it was related to something else. Are you by any chance testing the gaming 5? I can understand if you can't say, though.

[chew*]

I can't share results or some info but board is no secret with youtube unboxing videos.

Yes its a gaming 5.

Btw chinook no i dont mind and those are samsung b die. Same bin i ordered just with rgb...were backordered so i grabbed non rgb.

[dasa]

good as place as any to move this i hope?

seems some bios updates may be needed for faster ram speeds

both asus b350 mb specs max out at 2400, x370 pro 2666, crosshair 3200
https://www.asus.com/au/Motherboards...form-Products/

looks like asrock is only claiming 2400 up to 2666mhz
http://www.asrock.com/mb/index.us.asp#AM4

while gigabyte and msi are claiming 3200mhz on all there mb
the gigabyte memory qvl only goes up to 2666 with 4 sticks of ram and no 16g sticks tested yet


apparently not the most reliable of sources but anyway

What we recommend is the following:
If fully populating a system with 4 DIMMs (2DPC), use memory up to a max of 2400MHz.
If using 1DPC (2 DIMMs) ensure they are installed in A2/B2 and use memory up to max of 3200MHz.

The indication I have received from HQ is that AMD has focused all their efforts on CPU performance so far and will release updated code in 1~2 months when we expect improved DDR4 compatibility and performance."

In short if filling all 4 DIMM's set your speed to 2400MHz and work up from there.
If using 2 DIMM's put them in the A2/B2 slots and a max of 3200MHz should be possible.

In our testing only the Crosshair board achieved 3000-3200MHz, the others were in the 2400-2666MHz range.

BIOS updates will come!

seems a lot of people are taking that as asus commenting on competitors mb as well with the 3000-3200 only on crosshair claim but i took it as referring to there mb only

[chew*]

Your best luck is going to be single sided.

Chances are if you end up with a double sided 8gig stick (no clue if they make them) your going to wall at the same point as 4 sticks populated.

16 gig double sided educated guess they do make. Double sided will likely cap at the 4 stick populated cap. Probably will not oc that well either.

4 doublesided...ehh be lucky if it posts.

[chew*]

Over 3200 might be pointless anyway.

For all i know 3200 might be pointless.

Needs to be tested.

[dasa]

there is some out there and gigabyte has tested CORSAIR 16GB 2Rx8 CMK32GX4M2B3200C16 DS <double sided as ok on there am4 mb
http://www.gigabyte.us/Motherboard/G...10#support-doc

very true some memory controllers in the past have hit a bandwidth limit where higher frequency made little difference even in synthetics at which point only reductions in latency mater

[chew*]

Cool. For info sake the memory shipped in ryzen box is corsair 3000 v5.30. Looks like its on the qvl. Ill note exact model when home from work. Not like theres an NDA on corsair ram in kit.

I correctly assumed it was hynix after researching plats v5.xx were hynix.

While i would like to order asus board now i think ill order the plats first. They are not in qvl so while i have gigas attention on bios detail...

Finding the sweet spot for speed latency on the platform is a tad more important for endusers than my personal ln2 adventures.

Great to see you back Chew , awesome tread. I will be spending some time around here again seince AMD it's back in business.

I heard about 2933 Mhz OC is working also

Great to see you here too my old friend , i'm on AM4 wagon too.

I am sure a lot of the reviewers will have many DDR4 kits handy.

The better ones from DDR4:
Samsung B, C, and D die
Hynix AFR and MFR

Hola Charles , great to be back !

Guys i need some help identifying wish ics are on this memory kit , Samsung B , C or D die ? They will go into a Ryzen x1800 built.
