  1. Laptops on Ryzen 5 2500u seem to run on standard 1200 MHz memory speed based on CPU-Z screenshots I've seen on the internet. So running at normal frequencies shouldn't be a problem for a notebook. I thought about trying a factory reset. EDIT: From what I've read, installing the OS once again from a USB stick will remove all the custom manufacturer tweaks and leave my system as it should be. Does it make sense to try that?
  2. Only one is removable and the numbers don't change at all. I noticed that when I plug it in the value jumps to 933 MHz and the system itself along with all applications (unsurprisingly) feel much smoother. When I pull the power cord out, though, the DRAM resets back to 400 MHz. It seems this is some kind of weird power management solution from Lenovo. I tried contacting their support agents from US and UK about this but they don't seem to know what can I do. Are there any ways I can change my memory frequency besides doing it from BIOS(since the laptop UEFI doesn't provide any memory options)?
  3. Accidentally checked the memory tab on CPUZ. It says my DRAM frequency is 400 MHz, while it should be 1333 MHz as far as I'm aware (I currently have 2666 MHz RAM installed). I tried changing it in the UEFI/BIOS but it doesn't have memory related options whatsoever.
  4. My CPU was running on max frequency when benchmarking for a span of several minutes without lowering the GHz so it doesn't seem to be the problem. Besides, building and running a 10-line program shouldn't put such a load on the CPU insofar as to cause throttling or overheating.
  5. Hi, I have recently bought a Lenovo Ideapad S340-15API (Ryzen 5 3500u model). Everything seems to be fine with the laptop except for one thing. After installing Visual Studio 2019 I ran a few tests to see if the code executes as smoothly as expected on a new laptop. To my disappointment, the IDE takes about 3-5 seconds to build and run a program as simple as "Hello World", much slower than my 10 years old desktop does it. So then I ran Passmark Benchmark on it and every component did fine except for RAM. Turns out my memory latency is 192ns, which falls in the 1st percentile :(. I learned that high memory latency is a frequent issue on AMD systems, but I didn't expect it to be THAT bad. Currently my laptop has two DDR4 2666 MHz memory sticks installed, one 4gb soldered on-board and the other 8gb Kingston I added. My question is - could slow compilation occur in Visual Studio due to high memory latency? If so, how can I mitigate the effect? EDIT: Btw I tried disabling the anti-virus to fix the slow compilation but it didn't seem to change anything
