So I bought a new PC and I'm looking to upgrade the RAM. Bought it on a really good deal, which I why I didn't go for a custom build(or one with as much RAM as I would've liked). It has an i5-9400F on what seems to be an ASRock B360M Xtreme, in this CyberPowerPC rig. There's currently a 1x8gb kit of ADATA XPG Z1 @ 3000Mhz(Running at 2667). I tried setting up an XMP profile, but after using CPUID and UserBenchmark, they both saw it as running at 2667(not 2666), which I found odd(so I disabled the XMP profile). Not here to get advice on setting up an XMP, maybe 2666Mhz is just the cap for the mobo, I really don't mind. I just want to know what I should do for upgading my RAM. I was looking to get 16gb(2x8gb). There are 4 RAM slots, but why should I use all of them. Also, I just searched it up(while writing) that the ASRock B360M Pro4(which this board is based off of) only supports 2666Mhz and lower. That means that I can't get anything higher even on an XMP to my knowledge.
I have 3 different ideas:
1) I get an identical 1x8gb of the same brand
Pros: Gives me the 16gb I wanted while saving one 8gb stick, I can also try to return the 1x8 if it doesn't work
Cons: Might not even work and also seems that a 1x8gb stick of the XPG Z1 is very hard to find
2) I get an identical 2x8gb of the same brand
Pros: Guarentees that I will get at least 16gb and maybe even 24gb
Cons: Costs more than just buying a cheaper 2x8gb kit of the same quality(by G.Skill or Corsair for example), I don't really need 24gb(but doesn't hurt), the ASRock B360M Pro4 only supports dual channel, so 3 might not even work
3a) I just get a 2x8gb @ 2666Mhz kit and just admit defeat at the hands of CyberPowerPC(Since I think they just bought a 2x8 or a 4x8 and split the sticks up into these PCs)
Pros: I know what I will get out of it, will be able to save even more since it's just 2666mhz instead of 3000 or higher
Cons: I get an extra 1x8gb of 3000mhz RAM(not bad) laying around, might not be the most cost effective way(Which will make me feel bad)
3b) I just get a 2x8gb @ 3000+Mhz kit
Pros: I know what I will get out of it, also helps if I decide to upgrade mobo(and CPU, since I don't like Intel chipsets and CPUs)
Cons: Costs a little more than 3a, I get an extra 1x8gb of 3000mhz laying around, even less of a cost effective way, might not even upgrade(could just sell)
I'm leaning a little towards option 1, since I may be able to just return the stick and live on. Option 3a is quite tight, with 3b falling slightly further and 2 just being not terrible either. Also, please excuse the crazy rambling in the first paragraph.
Thoughts?
