Ryzen memory nightmares

[DDebbil]

I'm trying to get a Ryzen 1700 up and running with an MSI X370 Gaming Plus motherboard, however it will not allow me to touch the RAM settings at all. On 'auto', the RAM runs 2133MHz, however even if I just manually set 2133MHz instead of using auto, the motherboard will not POST. Needless to say, no other speeds or settings can be set either. I've tried it with several kits of RAM, including some Corsair LPX that I thought was on the QVL, but when it turned up it was the right model but a different version (ARGHHH), but since even manually setting the default speed won't work, I don't think that's the issue. I have the latest BIOS from MSI on the motherboard.

 

Does anyone have any ideas how to fix this problem?

Check the guide for Ryzen ram in my signature

I have the same board (and until the 2700X released the same CPU as well) and I've had 0 issues with Corsar LPX. Try to overclock the CPU before touching the RAM settings. Until I OC'd my 1700 it wouldn't really run the XMP profile either.

The only thing in the RAM guide I hadn't tried already was manually setting the SOC voltage. I tried at all the settings on the side of the RAM but with 2666MHz instead of 3200MHz, and with the SOC set manually at 1.2V - but same result: no POST.

Regarding overclocking first, I also tried setting 3.8GHz @ 1.35V (I know it will run 3.9GHz at that voltage), with all the memory settings mention above, and the result was no POST again.

What about loading xmp profiles? 

[DDebbil]

Neither XMP profile would POST.

Are you sure you RAM is installed correctly in the right slots? (I remember MSI having a different color lay out for their slots)

You want to use channel 1A and 2A (1 red slot, 1 black slot)

By the way, does your motherboard do what looks like an extended memory test as part of its POST procedure (lasts about 10-15 seconds)?

This could be the issue - I have the RAM installed in A2 and B2 (both red lanes).

[DDebbil]

Well, I changed to A1 and A2, but the motherboard flashed up a message to say the RAM was in a non-optimal arrangement, and directed me to put it back into A2 and B2. According to the manual, A2 and B2 is the right arrangement.

Happend to me too, MSI just likes to do things different

That is odd though, I took this image straight out of the manual of your motherboard

[DDebbil]

I think for dual channel you need one stick in the A channel and one in the B channel.

Always insert memory modules in the DIMMA2 slot first. it says in your guide, so it seems like you did correctly there..

1 module in A2 and 1 module in B2

Nope. POST takes about 5-10 seconds after pushing the power button on mine. 

[DDebbil]

Hm - the latest BIOS did improve the POST time a bit, but it's about 10-12 seconds before the top two LEDs go out, and another few seconds before the screen comes on.
