PC Building

[SteelCondor]

Hi All,

I've been struggling to get my new PC to run my ram sticks at the advertised 6000m/t.  I can only get it to run at 5800 or lower.

at 6000, it will boot and do non-taxing work/processes but anything taxing will eventually freeze my entire system. no BSOD, no useful event logging (that i've found). just freeze.

Now i realize the difference between 6000 and 5800 isn't great but at this point it's an educational endeavor for me.  What am I doing so wrong that I can't use the ram at the advertised speed? 

I started with expo only: crashes

disabled expo, remained at 6000: crashes

dropped to 5800 and set the timings to "tighter" in the bios. Perfectly stable.

System Specs:

CPU: 9800X3D at a CO of -28

Motherboard: MSI B650 Pro-S

GPU: Zotac 3080

Ram: G.Skill Trident Z5 Neo 2x16 (on the QVL)

PSU: 800w Corsair Gold+

You might need to tweak the voltage settings of the RAM, but that's something I do not recommend.  You should at least look for a BIOS update for your MSI B650 Pro-S motherboard.

Hi BigAl,

My bios are actually the most up to date version. i've tweaked the DRAM voltage to 1.4v from 1.35 as well. 

Still won't do 6000mt

[Hiramabiff]

make sure your ram is on the qvl for your mother board, also make sure your mother board bios is fully up to date. 

My issue with corsair was fixed when I changed to GSkill with a bios update. 

Even though the corsair was on the qvl, it created issues. I found corsair to run bad on a msi board, Gskill always fixed the issue for some unknown reason. 

On my ASRock build it hated corsair memory. Yes the qvl was exact. major problems. went to gskill and problems fixed. 

conclusion, 

gskill rocks, 2 different mother boards, corsair sucks 2 different mother boards. don't purchase corsair.

Hi Hiramabiff,

My ram is on the qvl, it is also G.Skill.

Make sure you have the latest Motherboard BIOS installed per Motherboard CPU LIST:

Ryzen 7

Granite Ridge

9800X3D

100

4.7GHz

8MB

96MB

B0

120

AMDRadeonGraphics

Latest Beta BIOS

Having the latest BIOS installed will help with RAM MEMORY compatibility.

I would open a MSI SUPPORT and G-SKILL SUPPORT Tickets and see what they suggest.

[SteelCondor]

Hi elstaci,

I saw that. My motherboard is on the most recent bios update as I saw its patch notes stated increased memory compatibility.  it didn't help however :(.

That's a good idea.  I suppose i came here first because I figured it might be a cpu thing.  I am undervolted a little bit (-28 CO) but i'm not sure if that's a potential cause.

Memory Context Restore to disabled instead of AUTO or Enabled. Normally forces the training during boot.

You could bump the VDD (memory voltage, some can only go to 1.4v others can reach up to 1.45v)  Check the memory vendor.

vSoC voltage could help as well but dont go over the safe point. In the last 7000 1.3v was the limit. Becareful with this setting.

Decrease CL to 40 and keep 6000.

Try other EXPO profiles or DOCP/XMP if available.

Check if the sticks are in the correct slots and clean the contacts gently with a rubber or isopropyl.

Sometimes Memory Context Restore enabled plus Memory power down can help, but this can shave performance.

Do try it out

Good luck

Hi JohnnyEnglish,

every time I try a new bios ram setting I allow it to train once before I enable MCR.  Is that enough?

My VDDR is at 1.4v actually.

Doesn't CL30 5800m/t to -> CL40 6000m/t generally result in a performance loss?

The sticks are in the correct slots: 2 and 4.  It wouldn't even boot when they were in 1 and 3 (which was what i did when I was building the thing XD)

[johnnyenglish]

Hi.

As for the MCR, its a picky setting. I cant leave mine enabled or auto, it will crash before even entering Windows. Since Im on a 21 segs boot delay, its not a big real and I can keep 6000 CL30 on a 7950X.

5800 CL30 is better but CL40 is more like a troubleshooting thing at the moment that you might want to try.

You can also, maybe, try older BIOS to see if it helps. But this is strange because 6000 today should be easy to attain. Could be a bad IMC, not sure.

Check for a piece of software called, Ryzen Memory Calculator, might help, it did helped me previously with my AM4.

[SteelCondor]

Interesting. I'm generally able to get into windows even with MCR on @ 6000m/t. It's only once i start actually doing anything remotely intensive that I'll freeze. I have ram power down disabled too if that means anything.

I attempted tCL 40 @ 6000m/t and froze in a similar way. Expo was still disabled.

I can't really try older BIOS as there are only currently two bios versions that support this CPU. I've used them both at this point. no one has been better than the other really.

I looked at Ryzen Mem Calculator and it seems too old at this point.  I'm running an AM5 processor that was released less than 2 months ago and the last time this software was updated was 2020.

[johnnyenglish]

You might want to enable memory power down with MCR enabled. That gives me stability but slightly worse results in gaming. Try it.

Whats is your current vSoC voltage?

6000 should be really easy, you might want to consider that you got something going on, either the board or CPU.

I'm running out dry here. Try see if Buildzoid tried something on How channel.

Hi JohnnyEnglish,

vSoC according to my bios is nominally 1.2v but it's set to Auto.  I haven't touched it.

I've now tried:

Power Down=Enabled +

6000mt +

MCR-ON

-----

Crashed

Power Down=Enabled + 

6000mt +

MCR-OFF

-----

Crashed

I do thank you for your advise and no worries if we can't figure it out.  yeah it could be my imc is just barely not good enough or the mobo isn't the best.  Either way I don't think it's so great a problem that it's worth RMAing but it is dissapointing. 

Ram has never played nice for me.  my last build was similar. coudn't xmp it without bsods so i had to just set it to what the cpu at the time was rated for and I left it there.  One day I will conquer the great ram mystery. 

[johnnyenglish]

On my previous system, the corsair kit had troubles with the 2700X reaching 3200 stable. So I had to increase a bit CL and bump vSoC voltage back then.

If your vSoC auto is 1.2v I believe you can go to the max safe limit, that should be 1.3v

However, I would do this with extreme care and step by step as this kind of tinkering can cause harm to your CPU.

My current kit is also GSkill.

[SteelCondor]

Ok. I know my CPU is fairly similar to the 7800X3D So i'll look into what VSoCs were working for people with my same issue.  I'll bump it up a little but i'll probably keep it beneath 1.25v to be on the safe side until I hear back more from MSI on the subject.

I think MCR and Power down mode should always be the same. So put both enabled or disabled.

Check also that GDM is enabled if you run 6000 CL30.

Asus boards I think also have 2x MCR setting in different places in bios and 1x power down setting so you have to make sure all 3 settings are same.

[johnnyenglish]

ASUS does have two locations for MCR but one does nothing. The one that does is in the memory settings page.

[atmosphere]

This might be a lot of work but did you try and reseat the cpu itself? 

When in windows does it show dual channel in performance monitor (mem-usage tab)?

[SteelCondor]

Doesn't really say anything at all regarding channel.  It does recognize 2 of 4 slots are being used. 

Cpu-z says it's doing 2x32 bit channel
