when i am gaming the ram temps go to like 45-47c max
My DDR5 (2 x 32GB) RAM is currently sitting at +55°C during a long 1080p to 4K upscale. I've run at these temperatures continuously for up to 36 hours. So far, so good.
The manufacturer's spec for my memory is Operating Temperature range: 0°C to +85°C.
i have enabled XMP becouse ram wouldy only work at 2133mhz without xmp,but ram is 3200mhz.
The stock (default) JEDEC speed of 2,133MT/s is typical for DDR4. This is the speed DDR4 RAM usually starts up at, immediately after you install the DIMMs.
If you want to overclock your specific RAM, you can then try increasing the speed to 3,200MT/s. Whether or not the RAM will be stable at 3,200MT/s (or faster) depends to some degree on your CPU and motherboard.
I failed to get some DDR4-3000 RAM to work at 3,000MT/s with an AMD 2600X, until I manually tuned some of the memory timings. The maximum officially supported memory speed for the 2600X is DDR4-2933 (not 3000).
The XMP speed of RAM isn't guaranteed to work in all circumstances. Sometimes you have to tweak the timings. Sometimes RAM doesn't work at the manufacturer's maximum rated speed and you have to dial down the XMP overclock.
