Memory O'C problems

[Hendricks3]

im currently running a r5 @4.1ghz with 16gb of corsair vengeance lpx @ 3000mhz on a msi b450i gaming plus ac. i tried to overclock the memory pass 3000 on an voltage when i run cinebench r20 the screen go undetected. anyone knows as to why?

the best way to figure out whats going on would be to set the processor back to stock settings and do your memory overclocking on its own. It could be a combination of your cpu+memory overclock isn't stable for some reason, but for trouble shooting reason you should rule out issues by testing at stock, and then your cpu and memory overclock separately

i did and the cpu @ stock the memory o'c runs just fine however if i o'c both at the same time it just does not work no matter the voltage i set them to

okay, good. Not everyone bothers to separate it out. There are a few things that might help with this:

bios updates - I would avoid updating to a 3000 series bios if your running an older ryzen, but the updates prior to those tended to help with memory overclocking stability for 1st and 2nd gen

SoC voltage - It is possible that a slight bump in SoC voltage will help with memory stability, but you have to be careful with it. On my own ryzen 3000 chip the auto voltage actually was too high for SoC so a slight drop helped my stability (can be very finicky to adjust)

Memory Timings - I hate to suggest it since you have obviously tried to improve performance through ram timing, but you may have to loosen out the timings or swap over to 2T

 

After you have stabalized things I would do a solid number of memtest86, conventional wisdom is 8 passes for solid memory stability

the mobo came with a really recent bios so idk but i will look into the bios update, im gonna look into the SoC voltage and see if it stabilizes and the memory timing i seen how to tie em but idk how to loosen them, would 100% appreciate a brief tutorial on it if possible

If you want some more detailed info please post specifics of your build ie:

Specific Ryzen processor model

Specific Ram SKU so that what type it is can be determined along with suggested timings

Current BIOS version

 

In terms of figuring out timings, once all this information has been gathered you can use https://www.techpowerup.com/download/ryzen-dram-calculator/ which is a useful tool to point you in the right direction in terms of ram settings

I'm not an msi mobo user anymore, haven't used one since K7 era so finding a tutorial for that elsewhere would be a good idea since I'm not 100% familiar with the menu organization

Try 1.368v voltage, that's the voltage my 3600mhz ram runs at.

[Hendricks3]

Ryzen 5 2600

Msi B450i Gaming Plus AC

16 GB Corsair Vengeance LPX 3000mhz 

Msi GTX Ventus 1660ti 

EVGA W 500W PSU

Sillicon Power 512GB SSD

it wont even @ 1.4v

Have you tried that exact voltage. Too much can also cause crashes.

no sorry i tried it @ 1.35v then 1.36v after when straight to 1.4v

in terms of bios, you want to be running at highest this version 7A40vA4
https://www.msi.com/Motherboard/support/B450I-GAMING-PLUS-AC

this specifically addresses some memory stability issues so if you are using an older bios update to this specific one. There isn't really benefits to using the 3000 series updates besides upgrading to a better cpu

 

edit: it looks like 7A40vA6 would be fine as well, but there doesn't look like a good reason to use it

let me check my bios update

I was doing some poking around and it sounds like the corsair dimms are hynix modules, I'm not sure which type specifically but if you read the product number/letter identifier you should be able to look it up. Use this info and the memory calculator tool to identify "safe" timings for a speed you're trying to achieve. This will also make suggestions of SoC voltages to try as well. Hope that helps.

the bios version is the E7A40AMS from 09/25/2019

that's a beta bios... where did you get that motherboard?

If it will let you try to replace that with the one I suggested, since you aren't running a 3000 series chip you don't need that new of a bios. Due to bios size limitations they had to drop some support for older parts in the newest iterations

 

edit: There's a good chance it won't let you downgrade the bios, if that is the case you might as well upgrade to the most recent one on their support page https://www.msi.com/Motherboard/support/B450I-GAMING-PLUS-AC

it came with that bios version when i bought it

weird. So anyway, since that is a beta bios I would try to change it. Are you comfortable updating the bios? I would suggest you do it while connected to a battery backup or something so that you don't accidentally brick the board if the power goes out

yeah i had a gigabyte mobo prior to this one which i upgraded it to the latest bios w/o any issues. again what do i need from the memory module to find out exactly the model of the chips

so i just checked and it looks like my lpx are micron D die
