RYZEN DDR4 MEMORY, WHAT YOU NEED TO KNOW!
- Thread starter Gibbo
- Start date
It's good to see they are catering to the DDR4 standard that AMD use as well as the separate DDR4 standard Intel use, was worried they might just try and make money off peoples confusion or something
This Ryzen RAM situation is a little confusing (and I can't find the post stating the freq differences you expect between 1T and 2T.
I have bought 2 x 8gb G.Skill Trident Z RGB 3000 C15D. I am trying to find out if this is single or dual rank. I am still in the window where I can return it and go with something else but first, does anyone know how to identify rank without opening the box?
If it turns out to be dual rank, will it still work but at much lower speed?

You can tell in the latest CPU-Z whether your RAM is dual or single ranked in the SPD tab btw.
F4-3000C15D-16GTZB
It'll work, just currently not hitting the rated speeds. Same with some single rank kits though, I've got single rank 3200mhz but can only run 2666mhz at the moment.
Should be a product code on the box that you can google or message Gkill and ask them about if it doesn't show up on reviews/tech specs. Gkills codes look like this...

When you buy ram at like 3000mhz, it means you have to overclock the ram, what is putting me off is that the computer won't boot.
Will xmp profile save the day?
Sorry but i want advice i haven't done this overclocking business and want some experience.

Which model is that you're thinking of switching too?

Dont buy ASUS get the gigabyte for now. I personally do not think the issues with the crosshair VI can be fixed via bios updates.

In my experience of Intel you can select the Hz for your RAM from a list in BIOS (I presume you can do this on AM4). This is separate to the XMP profile. In two builds where I have previously just set the RAM via that method I have then switched to the XMP profile. In both cases that resulted me in having to reduce my CPU overclock.
XMP profiles are Intel profiles. I would be holding my breath if I was to instigate the XMP on AM4 boards. Indeed one of the tech people on YouTube outright killed a stick of RAM by switching to the XMP.
In other words XMP could ruin your day rather than save it.

Currently kits on the market are validated on Intel platforms. When using memory that has been binned on another platform, there is even less guarantee of it working at the rated speed and timings, depending on the density and speed of the memory kit. XMP is simply a table in SPD that lets the user set various settings from within the BIOS. Normally this consists of purely the primary timings, VDIMM and frequency, but can also set other rail voltages depending on what the memory vendor wishes to specify. It is by no means an assurance the kit will run without needing to be dialed in - even on the platform and board the kit is validated for.

Because of my long term proclivity for AMD, I have always had to buy Ram which was Intel approved as there is or was no or very little ram AMD approved. I have had few problems running at the rated speed and CAS settings by manually setting in bios. This takes a little longer and often needs more voltage than the nominal. I have done this on several motherboards, Gigabyte, Asus and Asrock for the 970/990/780 chipsets as well as previous DDR2/DDR/PC133 etc. memory systems.
Yes it may affect the maximum CPU overclock, however I check system throughput ie GFlops etc. in addition to absolute frequency when deciding the optimal performance. As long as it is overclocked, the maximum frequency is academic.
I have 2 x 8Gb of G Skill 3200 CAS 14 Ripjaw waiting for Ryzen, not inexpensive (£140 incl.) we shall see.
just changed my order to this myself, loved the look of the asus but just keep hearing to many problems, also was told possible gigabyte delivery incoming friday but not known what exactly

Interesting, i have a set of 16GB Ripjaws 3400mhz CAS16 though, will be interesting to see if yours work, are yours double sided modules? i had a look at mine last night and they are, which is a bit worrying.
Soldato
Without removing the heatsinks, and I cannot find it written down anywhere, they appear to be single sided modules. They are samsung branded memory.
Soldato
It doesn't matter if they're single or double sided. It matters if they're single or double ranked. You can get 2 sided single rank memory.

How do you tell if they are single or double ranked then? i cant see what brand the mem is either.
