Question help with RAM

[Allame]

I want to upgrade to 32GB RAM I'm using this one HX432C16FB3A/16, and I can't find the same one anymore to buy it. the only option is to buy this KF432C17BBA/16, its same speed and company. does it work?

buy a 2x16 kit.

the timings are different at 3200 MHz that could pose an issue.

arnt both the same timing?
edite : c17/c16 so not same

Yes, I was looking at the product sheets for each HX and KF and noticed the XMP timings were different. You might be ok if running at 2400 MHz, or aligning the 3200 MHz timings in BIOS but not worth the risk IMO.

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.
Fortunately, Intel is relatively tolerant of mismatched ram.
This is more difficult when more sticks are involved.
Ram must be matched for proper operation.

What is your plan B if the addition does not work properly?

To avoid possible problems,
I suggest you buy a 2 x 16gb kit and sell the old ram or keep it as a spare.

You can sometimes compensate for errors by increasing the ram voltage in the motherboard bios

Running mismatched ram in the past I put the slower ram in the primary ram slots, channel 1, slot a, channel 2, slot a and I put the faster ram in slots b.
I was able to run xmp and it was stable with the faster ram dialled back to the slower speeds.

You really are better off buying 2x 16GB sticks and putting the memory you already have to one side.
Even matched memory can have problems working with 4 sticks, there are always tolerances.
