Ram Mixing

[JinnXV]

Hello, 

 

I have an older PC that I'm trying to upgrade the ram for, currently, I have 16GB (2x8GB)  CMK16GX4M2B3000C15B V5.39

I'm looking to get another pair of 16GB (2x8). I have found some with the same serial number and timings however the version number is either V5.30 or V5.32 I am wondering if this would work in my system?

 

Should I consider dropping the blue colour kit and try and find a black kit that has the same version numbers?

If your RAM modules have different voltage and timings, they may not work well together, and they may cause errors, crashes, or performance issues. For example, if one of your RAM modules has a higher voltage than the others, it may overheat or damage the rest of the modules or the motherboard. If one of your RAM modules has faster timings than the others, it may cause data corruption or latency problems.

some ram will work some wont... if its duel channel then i thin you need 2 sticks the same but if you got 4 slots the other 2 can be different.

This genuinely sounds like its out of Quora. XMP or the standard JEDEC profile provided in the board would automatically adjust voltages anyway. The bigger issue would be timing balances that would dictate stability, because kits are designed to work with only the pair that's in the box not with other sticks. Its not the end of the world but if you're not willing to tweak around you're going to be better off buying a 2x32GB kit, and sell your existing 2x16GB kit.

People take the rule of thumb of dont mix ram and turn it into an unbreakable gospel rule... It's so weird. 

Its a rule of thumb, you can break it. Given that the ram you are looking at are the same timings, same sub timings, just different revisions, the odds of issues or even performance regression is minimal. The odds exist, it's minimal. You are fine. There is no strong reason to throw out the perfectly good ram you have to spend more.

And get pennies on the dollar. it is just not worth it. Even selling ram NEW on ebay/craigslist/facebook market place takes forever at used pricing. Used ram is not a particularly liquid asset without fire selling it. That is way more of a headache then taking the .1% odds of the mixed ram not working at an acceptable level that you can just return if you roll snake eyes.

I mean depends on the market. I sold a shitbox 2666 2x4 kit for like 70% of brand new cost within 2 weeks.
