Enabling XMP Doesn't Post

Ryzen 5600X

2x8GB G.Skill Ripjaws V 3600Mhz

ASRock B550 Pro4

 

So I've noticed my memory was running at 3000Mhz. I know I have to OC anything over 3200Mhz but I've seen XMP doesn't really work over 3200Mhz even though the profile says its setting it to 3600Mhz. Though at this point I have no idea where to go from here. I have no idea what I should be doing to OC memory to get the 3600Mhz it can do.

The first thing to do in cases like this is update your BIOS to the very latest version.

 

Your memory is actually the perfect speed for a 1:1 ratio on Infinity Fabric to RAM, there should be no reason for XMP to not work.

 

Also make sure XMP is increasing the RAM Voltage up to 1.35v and is applying the correct timings.

Make sure your timings are 16-19-19-39.

So my BIOS is one version behind. I will update and post back the timings the XMP is trying to use.

@PorkishPig I tried manually setting frequency to 3600 with 16-19-19-39 but still wouldn't post after I saved to it.

Are your memory modules in slots DDR4_A2 (2) and DDR4_B2 (4)?

Your board's QVL doesn't show support for G Skill 3600 modules, anything not on the QVL is a gamble on it working out of the box. You'll like need to manually tune it or it just won't work at all.

Indeed they are. Am I kinda forced to manually tune everything to get it to posisble work at 3600mhz?

I went looking earlier but my only question is why is the 3600 in the xmp setting?

The memory comes with the settings and the BIOS picks them up as an option. I can't really think of an analogy for it. My memory is also rated for 3600 but was a few letters off the supported SKU and I can only get it to 3466 stable so far, obviously it's not ideal for Ryzen so I dropped it to 3200 and am waiting on new BIOS updates for stability.

I gotcha. Do you happen to know of a board supporting Zen 3 and 2/4 3600?

Your board supports those, just not the specific RAM modules you have. You can probably google QVL and your RAM serial and get some results.

QVL's mean nothing, manufacturers have to pay to have DIMMs verified and added to the list and most simply don't bother.

 

These days RAM is RAM, G Skill RAM is known to be good stuff and work fine with AMD based systems.

Do I have to manually set the FCLK....go through all the timings...I'm just not sure where to go from here. Manually setting to 3200Mhz with default timings works but if I go above that, or use XMP...it doesn't post.

QVL is a list of verified modules, anything not on it means it may or may not work from default XMP profiles... You'll need to manually tune it if XMP doesn't work, and even then, it might not work. The RAM is rated at it, but that doesn't mean the motherboard will cooperate at those default settings. You'll likely be stuck at 3200 until you find the timings that work with your particular board or they add more updates that tweak the BIOS and support more RAM. In my BIOS updates it literally lists "Added more RAM support" as a feature.

No, the entire point of XMP is that the rated speed information is stored on the modules, the board should just read and apply the settings and it should just work.

 

Try resetting the BIOS to optimised defaults then applying XMP just in case there's another setting somewhere throwing one of the clocks out.

 

Failing that you could also try boosting the SOC Voltage up to 1.15v just in case the issue is the IMC on the CPU.

You do realise that memory management is done by the CPU these days, right? The board does nothing other than provide the data bus from the RAM to the CPU.

 

QVLs are totally useless, they provide nothing of value at all. Memory issues are caused by either a bad DIMM or a bad IMC on the CPU, not the motherboard.

I've tried the bios reset to no avail but changing the soc voltage. Is it a fixed voltage or offset?

Fixed voltage, you can go as high as 1.2v with no cooling.

 

For context, Ryzen CPUs have a small SOC inside them that handles a few tasks that used to be done on the northbridge, one of those tasks is running the IMC (Integrated Memory Controller). If you got really unlucky on the CPU lottery you might have a CPU with a weak SOC that cannot handle running the RAM at 3600Mhz.

 

If at all possible it would be really useful if you can stick the RAM in another computer and test XMP. That way you'd know if the fault was with the RAM or the CPU.

I'm trying a 1.15v SOC. But figuring the XMP is setting it to 3600Mhz that is cl19, if this doesn't work should I just try and lower timings at 3200Mhz, or does it not work like that?

If that doesn't work then turn XMP off, boot into Windows, download CPUz, run it, open the SPD tab, select a slot with a module in from the dropdown then take a screenshot and post it please.
