Constant Memory Problems

[finkangel]

First post here looking for advice for a problem with overclockers prebuild.

I bought a prebuild in 2019 and it ran with little problems until recently when i tried to upgrade the ram. Initially I tried to add 2 more sticks of ram to the existing but that was unstable and wouldn’t post half the time. I tried again by replacing the original with 2 sticks of 16gb, but ran into the same problems. After updating the bios and resetting through CMOS and few times it was still unstable, however now that i’ve put the original ram back in the problems persist.

Could anyone give me some advice on this issue, should I revert the bios back to its original settings? XMP has been enabled and i am testing without but 2400mhz memory is not ideal.

Specs:
Ryzen 7 2700x
zotac rtx2070 amp extreme core edition
gigabyte b450 aorus elite

original ram: nighthawk 16gb(2x8) ddr4 3000mhz PC4-24000C16

1st ram upgrade: crucial 16gb(2x8) ddr4 3200mhz CT2K8G4DFRA32A
2nd: crucial pro 32gb(2x16) 3200mhz CP2K16G4DFRA32A

 

[something daft already!!]

Is it stable without XMP enabled? Have you tried increasing the voltage slightly to the RAM or tried different slots?

seems to be stable without xmp at 2400 but still testing, using slots 2 and 4 and changing them doesn’t seem to make a difference. I was hoping to use a higher clock speed for my ram than 2400mhz. Without xmp I’ll try increasing to 2800.

Is the new RAM using the same settings and in the same slots? Note that if you're having problems in Windows, there is a possibility that unstable RAM can corrupt files saved to your SSD.

Afaik the 2700X isn't really ideal for running 4 sticks, these CPUs had fairly weak memory controllers, but running 2 sticks shouldn't be too bad.

Note that the latest BIOS on these boards might not be well optimised for Zen+.

Yeah, for the 2700x, 2x 16gb I'd configure it to run ddr3000.
3200 was a tough ask even for 2x 8gb for the 2700x

I think you need to delete those links and just post the ram details because they are a competitor.

CT2K8G4DFRA32A
CP2K16G4DFRA32A

I quickly looked up the second set and they appear to be CAS 22 which seems slow to me when most of the 3200 RAM Overclockers sell looks like its CAS 16, I think CAS 14 was the high end stuff.

Have you considered buying a newer AM4 cpu for that "gigabyte b450 aorus elite" to take advantage of the performance improvements and the better memory controller which would help fix your memory problems?

Maybe send the kit back and get one rated for 3200 C16 so you can make the most of it if you ever decide to upgrade the CPU?

set XMP but manually adjust the ram speed to 3000 or 2800 if that isnt stable.

 

[Journey]

Just swap your CPU, 2700X is a PITA.

 

[ATIorNvidia]

Clear the CMOS and try to manually run at 3200 without enabling XMP. Is the BIOS on your board stock form Gigabyte or provided through the OEM/Prebuild company?

Try running Memtest86+

Update:

Tried multiple things with BIOS and diffrent sets of ram. In the end its stable running at 2800mhz using the original ram sticks. I appreciate all the suggestions but I have tried all these fixes multiple times (clearing CMOS, running memtest, using earlier bios). In the end I'm still unsatisfied with the overall performance of the pc and decided to get a new prebuild after 5 and 1/2 years of using this one, due to having to run most of my games on fully low settings with DLSS. My original aim was to increase the performance slightly with RAM so it would last me another few months but realising I would likley need to replace the motherboard and cpu, I just decided to go all out.

Thanks for the all help regardless.

Are you going AM5 then, what GPU have you gone for?

fully low settings with DLSS

Surely thats a GPU limitation and changing RAM wouldn't help?

aim was to increase the performance slightly with RAM

From what I've read with older AM4 CPUs populating all four RAM slots often meant running the RAM at a slower speed to get it stable so it could have had the opposite effect.

need to replace the motherboard and cpu

You could have got a newer 5000 series AM4 CPU thats one of the main benifits of AMD they don't change the socket with every release. The newer AM4 CPU's are faster and have better memory controllers so the RAM would have had a better chance of running at 3200 that said the corasir RAM kit you picked seems poor at CAS 22.

I had issues with my 2700 in the past as well with 4x8gb 3200Mhz and it would only run at 2933Mhz. As soon as i upgraded to a 5800X i could set the speed at 3200Mhz/XMP and didnt have a single issue.

I would also gone for a 5000x series ryzen and you would have not had much of an issue running that memory at xmp. Older AMD CPUS (I have owned 1800x, 2700 and 5800X and built hundreds of all gen AMD Ryzen CPUS) and i can confidently say that the earlier iterations of the CPU were very very finicky with memory.
