Memory Tweaking Help

[Yazzia]

Hello, long time reader first time poster!

I recently got a good deal on a 3900 non-X, and the memory I'm using is giving me a lot of trouble.
According to Thaiphoon Burner it is B-die 3600MHz chips so it should be fine to run at that, however the system doesn't even post when using the XMP settings.

I have also tried using the Ryzen DRAM calculator on the 3600 - Safe setting and it also refuses to post.

Any help would be appreciated!

Wow, that CPU is supposed to be for OEMs only...

Don't use XMP, as it's really quite hit and miss with Ryzen systems.
Did you set the correct memory Voltage according to the stickers on the RAM?
What's the actual rated timings of the modules?
Your system spec and Taiphoon burner seems to have different ideas in terms of what the modules are.

Yeah I was confused at first, a webstore in the UK is selling them alongside motherboards.

That is a picture of the sticker on the modules, they are definitely D60G as the heatspreader on the D40s is totally different.
I will double check the voltage but I'm confident I set it correctly.

Are you running 8 Dimms?

No only 2

I've just tested the DIMMs in a Z370 board I have and they work perfectly fine in that board with a 8600k.

It occurred to me that I hadn't tried the other slots on the board, so I did that and the memory works as intended now. Never had that problem before but live and learn!

His board only has four slots... Want to explain how eight DIMMs would be possible?

A lot of boards have a specific way on how to insert the DIMMs these days and it varies a bit from board to board.
At least you got a board with daisy chained memory layout, so you should be able to overclock it from where you are now, if you're interested in that kind of thing.
I would test the safe settings in the DRAM calculator for sure, as the standard latencies for those modules aren't great.

Glad you got it worked out Yaz.

Yeah I just got the safe settings working now, don't think I'm gonna mess around without any more today

If those work, then you're pretty golden, as the safe settings for your modules aren't half bad.
Would be interesting to see an AIDA64 memory benchmark.

Try fast 3533, also make sure your ram stay cool.

I didn't say it was possible, and obviously I didn't check.
I questioned due to the Ram showing as a 8x8Gb set

I kind of expected you to be under 70ns with those timings, but still not bad. Try tweaking the Trfc down a bit, it might help, even if you don't want to change anything else.

This will help a lot.

Those are very decent timings.
