Hello, I just recently upgraded my ram to samsung 3600Mhz. I am able to run it at 3600 on my b350m Pro4 board in Windows 10. Only problem is, when I use the program LatencyMon to check my numbers, it tells me my system has a hard time handling real time audio and to update my Bios to fix this issue. I get constant huge latency spikes. Aside from the Latency issue, my system runs fine with my ram settings at 3600Mhz. When I lower the Mhz to 3200, I don't get any errors or spikes. Anything above 3200MHz causes latency spikes. I tried increasing the voltage on the ram to 1.4v(highest I can go on this board) but the Latency problem still occurs. Any idea as to why? Any possible solution to reducing latency without lowering my rams default speed? I am on the latest 6.00 BIOS. |

should be a mem error problem use a proper memtest if there are errors that should be causing the latency but then again you didnt state your system specs not what latency numbers youre gettingin your test. it could be a ryzen 3000 with an unequal fclk -------------

Thanks for the reply. "it could be a ryzen 3000 with an unequal fclk" I have no idea what this means. I am currently running a 3800x at default clock speeds. Someone else suggested I tinker with the chipset/board voltages. As for memory testers, I heard those things are not very reliable/accurate. I was thinking of trying Prime95. I have no blue screens/crashes/freezes or audio stutters with the ram at 3600. Everything runs fine. The latency issue has me wondering if games will perform worse(more stutters,frame drops) If latency has no effect on this, then I was thinking of just leaving it at 3600 despite the spikes latencymon tells me Im getting. |

The infinity fabric (the architecture that connects the 2 clusters of cores or "CCXs") typically runs at the same frequency as the RAM, with Ryzen 3000 however it is now possible to run the IF (fclk) at a lower multiplier which enables higher RAM frequencies at the cost of latency. The difference should be negligible but some RAM combinations may not play nice with it. That said, most games prefer frequency when it comes to RAM so I would just give it a try and see how it plays. You can use something like MSI afterburner to check your 0.01% lows in both configs and see which gives you the better experience, 3600 or 3200. As for audio, "live audio" refers to audio recording. You want as low latency as possible when recording tracks and keeping them time aligned, playback is not an issue however. It would effect streaming audio too but no one will care if your speech is 0.01s off time to when you said it  If you will not be doing any multi track recording (making music for example) then you don't need to worry about it. -------------

| I appreciate the info. I will most certainly try out MSI and see how it performs between the two. Thanks again. |
