Mixing memory

[Smarajit]

So guys last year I bought the following setup:

- AMD Ryzen 5 3400G(https://www.amd.com/en/products/apu/amd-ryzen-5-3400g)

- VENGEANCE® LPX 8GB (1 x 8GB) DDR4 DRAM 3000MHz C16 Memory Kit - Black(https://www.corsair.com/eu/en/Categories/Products/Memory/VENGEANCE%C2%AE-LPX-8GB-%281-x-8GB%29-DDR4-DRAM-3000MHz-C16-Memory-Kit---Black/p/CMK8GX4M1D3000C16)

- RX Vega 11

- ASUS PRIME A320M-K(https://www.asus.com/Motherboards-Components/Motherboards/PRIME/PRIME-A320M-K/)

Now the point is I want to increase my memory to 16GB, but the identical memory model is expensive now here. So I surfed a while and found some sweet deal on these ones:

-  Adata XPG Gammix D10 8GB (8GBX1) DDR4 3000MHz(https://www.xpg.com/us/xpg/486

- G.SKILL RIPJAWS SERIES DDR4 MEMORY MODULE (8GB X 1PCS, 3000MHZ) (https://www.gskill.com/product/165/184/1594188700/F4-3000C16S-8GVRBRipjaws-VDDR4-3000MHz-CL16-18-18-38-1.35V8GB-(1x8GB) )

Therefore should I mix memories?

You always should try to avoid it, but in theorie there is nothing wrong as long as you et the right speed (wich seems to be true by looking at your Text above).

I suggest you do not mix ram. Can and will have a plethora of issues. 

 

2x8gb kits can be had for cheap nowadays.

 

For instance:

Whatever you end up getting, get a match pair as a kit.

I have 3 different types of DDR3 in my computer and it has been stable for years, the average user post stated back then never mix RAM. But maybe I was lucky as you might see when reading further. Only thing I had to do is set all modules to the lowest modules settings for all 3 brands to work.

 

DDR4, honestly if there are only a limited amount of actual chip makers who then get rebranded, all you have to be concerned about is are they all from the base chip maker? There are more than 3, perhaps 4 or 5 I've managed to research now, and none of them make it clear they make chips for other people. Presumably so they don't cut their own throats by being undercut.

 

But I'm going to stab that only an engineer can tell you why you can mix the makers and make a educated guess it is more down to the controllers to the RAM being different makes, not the speed as stated on the bin. Two different might make the drivers act schizophrenic and cause a CPU nervous breakdown? I might add copyright as a suggested cause as it might force the makers to have these RAM differences and it is this that makes them more likely to be incompatible with each other.

 

However, in saying that I saw Toms Hardware state you should not even add additional RAM kits of the same type!!! ie buy them as 4 modules kits if you want 4 sticks, and only use  1 kit of 2, and never adding a second kit of 2. This might be down to the fear of different makers supplying to the same brand, they never said, but I was quite surprised to read that never mix statement.

 

I can also say not all RAM is made for your CPU, you have to read the small print. If it doesn't say made for AMD, don't risk it, avoid it, and to back that up I read a few buy complains of how G.Skill Royals would not work with Ryzen CPU, but G.Skill only ever wrote it worked with Intel on the pages I read those comments.

 

I sure would not want to mix up banks like I did with my DDR3.

Besides with all the cosmetic differences you lose all that when you mix em up and it might end up looking pants. All I might mix and match might be just be down to same brand but red and white colours, gold and silver, etc

 

final word. I'd say get a kit of sticks and don't use that single stick anymore. Look at the Hyperx Fury and Crucial Ballistic brands as not only are they generally budget priced and they are one of the few I see claim made to overclock, the other brands don't, but you'll find those brands have a host of speeds so they  must be binning them to charge you more I believe. Go for 3200mhz seeing the Motherboard says it supports that as an O.C. and don't limit where you search for deals, use e-bay, amazon, web shopping tabs in go duck go and google, dedicated web sites that look for you like pcpartpicker, use every method you can think of and snap it up when you get the deal you can afford. Heck even buy from a different continent if they agree to ship it to you. You probably will do anyhow and not even know it as your local shop might have been supplied from China or the USA?
