Default WTS: 16GB DDR4 Performance RAM

Hello everyone!

A friend of mine got this RAM as a gift (a year ago) but it wasn't compatible with his computer. Unused, but I have no way of testing it.

AX4U2800W4G17-BWZ

DDR4 2800 (17) 4GX8
1.2V 10400080

Shame, I wanted to get an extra 16gb ddr4 but as 2x8gb. Are these SODIMM?
Good luck with your sale.

No problem!

I don't have anything compatible with DDR4 ... I have one machine that'll take DDR3, so no use to me either . Everything else I own is DDR2 RDIMMs or UDIMMS.


These would make a nice build with AMD's new Ryzen CPUs.

Yeah all the new pc's use ddr4. in my build I just completed a couple weeks ago I use ddr4, however I got 2 8gb sticks. So i couldnt use these either. You cant mix and match ram speeds and sizes. All have to be the same speed/size

If by speed you mean for example mixing DDR3 with DDR4, then no, that can't be done. But you can often mix differently clocked RAM and RAM that is a different capacity on the same MoBo.

Although, most of the time you need to have matching capacity modules in the same channel. You can have 2x 8GB sticks on one channel and 2x 4GB sticks on the other for example. AFAIK I've never encountered an issue with that on any dual channel motherboard.

As for different clock speeds, the MoBo will usually reduce the clock speed on the faster module on a given channel to match the slower module on that channel. Other specs of the modules need to be the same though, rank for example.

Best practice is to have all matching modules, but it's not necessarily a requirement, to a certain extent anyway.

Yes, you can mix up ram to some degree. I've seen 48gb rigs in the past, however it is advised to stick to binary numbers for the total.

Yep, we had a bunch of Lenovo desktops with 3GBs of RAM (Intel i5s too) at my last job, think we were using 2x 512MB and 2x 1GB in those.

You can get some interesting configurations in servers, seeing as they often have more than just two channels nowadays. Although, you usually need to follow the best practice configuration for each specific server or it'll complain whenever you reboot it.

Proper configuration is a must if you want to benefit from some of the available memory redundancy options in modern servers.

512mb of ram is redundant nowadays. How long ago was this?

Uhh, two years ago or so. It was all DDR3, the machines were older than 2 years though, maybe 6 years old by now. It was definitely 512MB DDR3, pretty sure those machines came from the factory with 3GB.

Interesting. It shows you how fast technology moves when it comes to computing. 16gb is considered ok to overkill nowadays but give it a couple of years 32gb will become just that.

Default Re: WTS: 16GB DDR4 Performance RAM

My laptop runs at 16gb ddr4 at the moment, but I want to future proof it by adding another 16gb to the last two slots. I was thinking about fitting out with 64gb but that is just expensive and overkill for now.
