Combining / adding new ram

[gracethegame]

So I have DDR4-2801 / PC4-22400 DDR4 SDRAM UDIMM in slots 1 and 3 (ram slots).
Can I add G.SKILL Ripjaws V Series 8GB (2 x 4GB) DDR4 2400Mhz CL15 1.2v Desktop Memory Model F4-2400C15D-8GVR 15-15-15-35 to slots 2 and 4?

You could indeed add them, but expect system issues, the answer is no.
Reason being do not mix ram with different brand speeds, voltages.
Tell me the model number and brand name of you're ram.
So that we can see what you're dealing with here.
Also give me your mobo name and model number so you can get more bang for your buck.

Hi thanks for the reply, I appreciate the time taken to reply. I think G Skill F4-2800C15-4GVR and ASUS Z170 PRO GAMING are what you're looking for. I was thinking 2x 4gb sticks of RAM.

I think it should work. The MB would just default to the slowest speeds. Just make sure the memory is listed on your MB's memory QVL, which can be found here. However, it is preferred and recommended to keep with the same memory and you will have less issues and the best possible performance by buying an all new kit with the capacity you want.

F the required voltage requirement between the two brands is different, expect problems. Over-volting RAM is common in situations when you're trying to raise its speed from its nominal speed. (In other words over clocking it).

AFAIK, the board won't compensate for voltage, but will compensate for speed, always running all the RAM sticks at the speed and timing of the slowest modules.

I doubt if you could indeed, over-clock mismatched pairs of RAM. But assuming you were inclined to install matched pairs , over-clocked RAM is always subject to instability, and shortened life span due to heating issues. And like CPUs, some brands and models, over-clock better than others.

I put up that last paragraph because it seems you're trying to get a speed bump by installing faster modules. You Won't

But, the funny thing is, "Windows Experience Index", rates more RAM, at a much higher index than the exact same memory at lesser quantities.

I'm not sure if that test takes into consideration the system "paging", when the computer runs out of the installed RAM, and is forced to write to the system drive.

Thank you very much for your replies. I just want the RAM to be compatible and work fine. I'm thinking another 2x 4gb sticks would be best as opposed to 1 8gb stick. There's a website I'm looking at getting it from "pbtech.co.nz" I have a budget of $200 if someone could give me assistance as to which RAM I could get that would be good. Thanks once again.

What you haven't told us yet, is the brand of the RAM in the machine, and why you seem reluctant to simply buy 2 more sticks of it...

In spite of how high priced as RAM is these days, you should still be able to buy a kit of 2 X 8 GB, and simply yank the RAM in the machine now, and pop 2 new 8 GB sticks in.

Here's the Gskill you're considering at Newegg in a 2 X 8GB set, for $183.00: https://www.newegg.com/Product/Product.aspx?Item=N82E16820232178

That would be the most reliable and fastest running solution.

Next best would be to simply buy another set of 2 X 4 GB set of the brand and speed which is already in the machine, and pop it in the empty slots.

Although you have to realize, the speed bump up to PC 2800,. isn't going to be as monumental as you'd like it to be...

Given your prospective budget, I think you're making this more complicated and difficult than it needs to be.

I would recommend you make whatever purchase you decide on at Newegg, in lieu of another supplier.

That only holds absolutely true if you're in the US or Canada. (Although the prices would be higher in Canada due to their weak dollar ATM).

Part of this discussion should be about what you'\re using as a system drive. Unless you already have an M.2 PCI-E SSD for C/: and are running out of RAM, your biggest performance bump would probably be in replacing the drive.

I prefer you get one stick so you will have less upgrading issues when upgrading to 16gb in the future.
Thats the best price tag you could ask for, if you want to get two 4gb for a higer price tag as shown on the site.
Thats cool too but don't say I didn't warn you, have a look at my ram here for a second:
https://www.amazon.com/dp/B00UFBZOVE/?tag=httpwwwtechsp-20

Thats in my system supporting my Core I5 7400, I haven't had any issues besides the recent lagging.
If I throw on another stick of that into my system I got 16gb and my system would do "MUCH" better than as it is.
If you think about it as long as that mobo will allow you to reach 32gb of ram without grief.
You got it made, think about what I said over time and do the match, I promise you won't regret it in the near future.

OK, the prices of durable goods in the ANZAC nations have absolutely nothing to do with prices here in the US. Particularly with computers parts and musical instruments, the prices down under often approach double those of here in the US.

As near as I can tell, the link you provided to the Crucial memory, was at Amazon in the US. I say this because they picked and offered to ship it right to my zip code here in the US.

In a final appeal to some common sense, why would you think running 1 x 8 GB stick of RAM which is only a few MHz faster in single channel mode, as opposed to the dual channel 2 X 4 GB which exists now, would offer any definable improvement?

Provided that the brand and speed of RAM extant in the machine now is still available, the most reasonable solution would be to buy a single 8 GB stick of it, stuff the 2 X 4 GB DIMMs in channel A, and the new 8 GB in channel B. Then you're done
