Ryzen 2600 persistent stuttering when under load/rendering

[badpcbadname]

So basically whats in the title. 

My rig is a 

Ryzen 2600 (On 3.8 oc with 1.3 voltage, but I get basically same results no matter what oc and voltage, including auto for both)

MSI B450 M-ITX Gaming Plus AC (MS-7A40)

Zotac Mini 1050Ti

G.Skill Aegis 3000mhz ram 8gb one stick (Set to 2933 with xmp)

Corsair SF-450 psu

Toshiba HDW110 (HDD, 1tb 64mb cache, 7200rpm)

120GB SDD (SPCC)

Noctua NH-L9a Cooler

FD Node 202

 

The issue is that when my pc is under load, like gaming or cinebench, it freezes for 1-10 seconds frequently. My CPU max temp under load is averaging around 75, so it is not overheating, even though these aren't great temps. I started noticing this issue recently, and my cinebench scores are the same, if not better than before the issue started. I noticed this issue before I oc-ed, and get better performance with the OC, even though it doesn't affect the stuttering. I really don't know what to do, I've looked up my issue and everyone seems to be having this on idle, not under load. My ram also seems fine, apart from being single channel. It worked perfectly on an older 1300x build I used to have. Any help would be great, Thanks!

2600 is more powerful than 1300x and thus requires more RAM to operate properly. Its held back by a single channel RAM.

I know it is theorectically being held back, but how would this be causing Stuttering? I don't see this happening, considering that the workload is much the same.

get into the BIOS, look for downcore control option, and drop your operating core count to 4 and disable SMT. That should let you test memory performance (though downcore itself is kinda buggy so it might not take effect)

Ok, thanks, I've done this. How would you reccomend that I test my ram, and what could I maybe do if this isn't the problem?

by 'test memory', I mean do things that were stuttering for you.

Ok, I updated my BIOS, GPU Drivers, With and without smt and downcore, andI am still getting stuttering at least for 5 seconds total in cinebench. Any thoughts on how to fix this? Thansk in advance btw

Do you still have the 1300X around for testing? Also with the 2600 at 3.8GHz you should get at least 1100cb multi core in Cinebench R15, is that the case?

No, I don’t still have the 1300X around soo can’t do any cross testing, but I do get an average of 1150-1230 cb score. It also improves after multiple runs, and doesn’t seem to be affected by the stuttering. When it unpauses it looks like it jumps to where it should be, so it isn’t a complete stop in proccesing, it’s some weird graphical error

I'm still suspecting the single channel issue, but I dont know it can be this bad

 

maybe it completely ruins the timings?
