Hi, a quick and maby usual question, but wich I couldn't find a rliable answer to in the web:
I will soon get a HP 255 G9 7N075ES NOTEBOOK with a AMD Ryzen 5 5625U prosessor, that contains only one stick of DDR4 SO-DIMM 8gb 3200mhz cl22 running at 1.2V.
I want to upgrade to 2 stick of 16gb each. of course, going with the original parts would be the safest way, but, when already replacing with new RAM, I would like to squeeye a little bit more out of it.
Nowing that it is absolutely no high end PC, I am a bitt worried about putting in Mushkin Redline 3200mhz cl16-18-18-38 running at 1.35V
As far as I understand, the voltage will most probable automatically be reduced to 1.2V and therefore also the memory speed.
You could ,ofcourse, manually force higer Voltages (1.35V) and timings in the BIOS, but that cuold be harmful, isn't it?
In particular the Voltage worries me, as I couldn't find useful information regarding it in the net. Neither i could find useful information about the motherboard used regarding RAM.
The best one with 1.2V I could find is G.Skil Ripjaws 3200mhz cl18-18-18-43. This would be the safer option, as I guss.
Or would it harm the CPU or motherboard to put 1.35V on it?
Furthermore, I have been told one should check, if I actually can sett the timings named by the manufacturer in the BIOS, because, apparently, some motherboards only support a very narrow range of different timings.


About a hint or short explanantion, I would be very glad. Many thanks in advance!
 
Ok ,thanks for the replies. Sad to get to konw about the bad compatibility.
So, theortically, if I am able to sett the timings for the new ram in the BIOS, 3200mhz cl20 1.2V JEDEC Ram should most probably work without issues, right?
Or does HP force its clients to buy its spare parts?
