Ryzen 3600 and Memmory settings : MSI B450 Gaming Pro Carbon AC

[Humbug]

Hello

 

I would like some assistance in getting my RAM to match the XMP spec exactly.

 

The RAM modules I own are these

2 x 8GB DDR4 3600 T-Force VULCAN TUF Gaming Alliance DDR4

CL19-19-19-39

https://www.teamgroupinc.com/en/product/vulcan-tuf-ddr4

 

It shows up correctly under the SPD tab of CPU-Z as the only XMP profile.

 

 

 

So then I enable XMP in the BIOS and it looks like the correct option in the BIOS as shown below.

 

 

 

However when I log back into Windows and check CPU-Z I can see the below issues.

CL is 20 instead of 19

tRC is 82 instead of 58

 

 

 

In the BIOS I cannot figure out how to tweak the TRC, I only have below options under DRAM configuration.

 

 

 

If I go to the advanced overclocking DRAM section I get this which I cannot make head or tail out of cause I am a noob to RAM.

 

 

 

Now there is an option under DRAM Overclocking called "Memmory Try It !" where you can pick from a list of presets. So for example I chose the below which works fine.

 

 

 

It worked fine but as shown in CPU-Z below my tRC is still at 82 even though the other timings look good.

 

 

 

System specs

Ryzen 5 3600

MSI B450 Gaming Pro Carbon AC WiFi

2 x 8GB DDR4 3600 VULCAN TUF Gaming Alliance DDR4 GAMING MEMORY

AMD Radeon R9 290 Sapphire Vapor-x

Try more than one monitoring system 

For cl latency it could happen if the imc needed to up the cl latency and couldn't get to the advertised speeds with the cl19 but the trc is really really weird Maybe try hwinfo64 to monitor the ram speeds

And update the bios

Verified with Ryzen Master. It confirmed all the CPU-Z readings.

BIOS is up to date.

 

Also as mentioned in OP my system runs fine even at 16-19-19-19-39, which is even a lower CL than what my modules are rated for, yet it's stable outside the XMP profile...

But the tRC value is still really high.

So manually adjust Trc back to 58.

This completely slipped my mind but do what @ShrimpBrime said and try manually setting it to 58

I wonder what the Trfc 1 is set to. There's a slight bit of performance gain getting that tighter. If it's 700 or higher, I'd manually lower that one too.

Yea I agree but I just noticed that OP said that they can't even change anything other than the cl so they can't even change trc or trfc

Yes he can.,

Just needs to click the "advanced timings configuration tab. You can see the option on the second screen shot in the first post.

When i click on Advanced DRAM configuration I get the below. I can only change the items under Main Timing Configuration.

From Sub Timing Configuration downwards everything is greyed out. Regardless of whether I am in XMP mode or not.

 

 

 

If I go the advanced overclocking DRAM section I can see the below which looks like greek to me. Can I change the tRC to 58 from here? If so how?

Go to Trc control enable it and then it should allow you to change the timing to what you select or type in the number pad.

Ok I did that, below is what I did in the BIOS. But look at what it says about the range of possible values on the right. btw when I enabled that control it defaults to 39 before I change it. Anyway I changed it to 58.

 

 

After I set it to 58 and log back into windows below is what I get. tRC has actually gone up further.

Lol that is far out! 

I'm not super familiar with MSI bios's, but that's f'ed up man lol.

Maybe it's just bad firmware or bios from msi 

They are not necessarily known for the best bios experience lmao

 Ya, but how do we help him with this?? Someone that has MSI experience could help.

My newest MSI board is AM2 chipset. Athlons and Phenom Agena core chips.

I remember a while back on the forums some one had similar problems with their ram and I think we concluded that the bios was shit and other people from Reddit where complaining about it and it ended up being the bios / uefi

We can't really do anything about it I suppose 

Other than maybe op reaching out for msi help

some good info on Actually Hardcore Overclocking on YT

Sorry to necro an old thread and OP has probably fixed it by now, but this might help someone else. MSI wants the DRAM timings entering in hex for some reason, not decimal.  Why MSI, why? It does actually mention this on the BIOS screen in the side panel though.

 

Using an online dec-hex converter, dec 56=hex 38. If you enter 38 in BIOS, CPU-Z should confirm that your tRC is now 56. Or at least it did for me.
