      I have a G443 power spec that I got in 2023. I recently updated my BIOS and when I went to adjust my ram I noticed the ram Frequency. Should I have my ram in G2 or G4? Also when it comes to fans should I have my cpu in PWM and in safe mode? Also should I put the Pump I. DC and the.n turn of safe mode? And should my case fans be In DC or PWM?

      This was all set up originally but I think my setting got messed up with the recent BIOS update I did and I’m new to the whole PC world? 

      Also when my AIO front fan speeds up it makes a auditable whining noise. Which it hadn’t done that till I updated the bios. 

      Any help would be great

      For the memory. Those are gear modes. Don't adjust this individually unless you want to delve into overclocking. Just load the XMP profile, it'll do all that for you.

      CPU should be in PWM mode. Does not need to be in safe mode. Pump is DC, I'd set it to full speed. Don't throttle it.

      The case fans all run through the controller on the back. It needs to be on PWM, otherwise it'll just run at 100%. Probably why you're hearing the whining sound. We set to PWM as default, stock BIOS defaults to DC.

      So if I put XMP will it override the frequency  I set yesterday? Or can I disable that? I already put it on a G2 option 

      And then probably a dumb question but how do I set the pump to max speed?

      also thank you for the response this helps a lot! I find BIOS very daunting

      It will and you should do that. XMP will set the frequency, primary timings, VDRAM voltage and may also alter SA/VDD2 voltage. Just change the frequency alone is very likely to cause some level of instability.

      Should be in the hardware monitor tab. Let me know if can't find it and I can check a board. The pump header should default to full speed.

      Edit: XMP won't touch SA/VDD2 behavior technically. That's board behavior coded to change when XMP is enabled. Only DRAM is actually set via the profile.
