Help with RAM OC

[Weeman94]

Hey guys

 

I just build my new setup and I don't really know how to get the 3200Mhz out of my RAM. I am completely new to OC so I thought, maybe you can help me to do it together.
If anyone is wondering why I need so 64Gb RAM, I manly use my PC for GIS stuff (remote sensing, R, Python, QGis,...) and as satellite images are quiet big I do need a lot of RAM.

 

Right now when loading the xmp profile the screen stays black and I have to reset the MB manually. I managed to run stable at 2666Mhz.

 

My setup:
CPU: AMD Ryzen 9 3900X
MB: ASRock X570 Steel Legend

RAM: 4x Ripjaws V F4-3200C16D-32GVK (so I bought 2 x 2x16Gb)
GPU: Radeon RX 580 8GB

CPU-Cooler: Noctua NH-D15

Power Supply: 750 Watt be quiet! Straight Power 11

 

 

Many thanks in advance!!

enable xmp and manually set dram voltage to 1.35 and SOC voltage to 1.1

[Weeman94]

Didn't work. I loaded the xmp profile, set dram voltage to 1.35 (was 1.350 from xmp) and "PREM VDDCR_SOC Voltage" to 1.1 (was auto).

After 2-3min black screen and no bootloop I reseted it manually.

Into which slots did you install the sticks?

[nick name]

Oh, wait.  So you have a four stick kit now and haven't received that 2x16GB kit yet?  If so disregard my question.  

[nick name]

So you combined two kits to get your 64GB?  That isn't ideal, but may not be the culprit.  The manual says 4 sticks should be supported at the speed you achieved.  

 

I'd recommend having a look at the Ryzen DRAM Calculator.

Your Ripjaws aren't listed in the QVL. Is it single-sided?

[Weeman94]

Using Thaiphoon Burner it is dual ranked. 

Organization
2048M x64 (2 ranks)

 

Die Density / Count
8 Gb B-die (Boltzmann / 20 nm) / 1 die

 

I bought the same kit 2 times.

I've got these results. Shall I just try OC my RAM in the BIOS with that setting?

yeah give that a try

Are you sure your kit is Samsung b-die?  

[nick name]

And no don't try those timings.  If you can't run 3200MHz at 16-18-18 then those timings aren't going to work.

Result from Thaiphoon Burner:

 

 

[nick name]

Hmmmm.  Then I'm assuming it's not quality b-die ie the one everyone buys for performance.  But you won't know until you try.  The thing that causes doubt is how you are having trouble now at higher timings.  

[Weeman94]

I will give it a shot later. However, would you recomend a different kit? Still have about 10 days to return them. If so can you recommend smth. specific?

 

Btw.: Thanks for all your efforts!

I'd just go with the qvl

Set up DOCP profile but set memory frequency manually to a lower than XMP frequency, say 2666mhz. Maybe even lower if need so to post up.

In memory timings menu, you want to set the Cas latency to 16. This will avoid the need to use the "Gear Down" feature where the board allows the  use of odd Cas latencies while it's known the AMD IMC is actually THAT picky about RAM. I do recommend running the Cas 16. It won't hurt the memory, probably respond much better for you. (16-16-16-36) Trfc, leave it auto. No need to change it. Tighter brings instability. You want some redundancy for 24/7 OC.

 

Set XMP - Target Mem speed lower, like 2666mhz. (this sets up sub timings for higher frequency, that's why this approach)

Set Memory voltage to 1.410v

Set SOC voltage to 1.1250v

If wanting to keep Cas 15 or any odd latency, You must Disable "Gear Down mode" which should be located in the memory sub timings menu. However I am not familiar with MSI, so it could be elsewhere. (This is why it won't post when you manually set up the target frequency btw.)

 

If 2666mhz posts for you, Please go to windows and test this frequency before heading out to more Frequency. We need stability first. If 2666 will not post, try a lower speed, maybe 2333mhz and so forth. 

 

 

Hope this quote helps.
