Ram over locking
Ram over locking
Hi everyone,
I'm relatively new to Ryzen building but have some experience with PC construction in general.
I recently upgraded my system from 16 GB of 320 MHz RAM to 32 GB and installed a B450 motherboard. Since then, I've been experiencing crashes in games, and I suspect the issue is related to the RAM.
I'm using XMP profile 1 with a memory speed of 3200 MHz. Is this sufficient for my system? Should I consider downclocking? Or am I doing something incorrectly?
Additionally, I ran a Mem86 test and received these results: test 7 address expected fdffffff actual fdffff7f cpu9.
This goes beyond my usual knowledge, so I'm reaching out for advice or insights from anyone who has dealt with this situation.
Thanks!
James
You might need to increase the SOC voltage slightly, but keep it below 1.2v. Raising the SOC voltage can assist with higher memory clock speeds. Additionally, you may want to boost the RAM voltage as well, though it shouldn't exceed 1.4v for 3200mhz.
Hey there
appreciate the help, what is a soc? I'll give it a shot now
This refers to a System on a Chip, or SOC, which is integrated into the memory controller on Ryzen and other components on the die. Raising the voltage on the SOC can assist in stabilizing higher memory frequencies. Certain boards may undervolt the SOC excessively, causing problems with XMP profiles on some systems. I wouldn't exceed 1.2v for regular use without adequate cooling.
I had to boost my SOC from 1.1v to 1.17v for my Threadripper setup because running eight RAM sticks and a 3200MHz clock was unstable. A slight increase in SOC voltage helped with random app crashes and occasional BSODs. This should be similar across most Ryzen models currently available.
Raising the SOC voltage will cause a minor temperature increase, barely perceptible, but pushing the CPU closer to its safe operating limit may slightly raise the maximum temperature.
That's great. Yes, overclocking works well. Everyone adjusts the timing too. Some people say it's essential. What are the expected improvements? I checked the DRAM calculator and have all the figures, but I haven't had time to enter them into the BIOS yet. Could be the boost isn't that strong.
