Hi all

There’re a ton of “what RAM should I buy” threads so here’s a DDR5 RAM buying guide from Buildzoid.


Mods, please let me know if this is not allowed but I can’t see why it wouldn’t be.

TLDR:

Want a cheap kit that you can overclock and is stable and fast? Get the TEAMGROUP T-Create Classic 10L DDR5 32GB Kit (2 x 16GB) 5600 MT/s

CTCCD532G5600HC46DC01​


AMD: go buy Hynix XMP 6000 MT/s CL30

Intel: 6800 MT/s CL30 A Die works on almost any Intel 13th gen.

For a good Intel RAM get Corsair 6600 MT/s CL 32 for good out of the box performance using XMPs.

24gig modules can overclock better than 16gig modules (will elaborate).

Intel memory controllers are all over the place and are often weak or even rubbish.

Z690 boards are no way near as good at posting high end RAM speeds as Z790.

2 DIMM motherboards are much better at DDR5 Overclocking.

Edit: Here's an Intel memory scaling guide from Hardware Unboxed with help from Buildzoid


Regards

Is that a 2 dimm board or dose a 4 dimm board that’s running just 2 dimm work just a good?

As Tetras said, it’s a 2 DIMM only motherboard rather than a 4 DIMM with only two modules installed.

You can get better stability with only 2 DIMMs installed in a 4 DIMM motherboard but it’s not as good as a 2 DIMM only board.

You’ll also see dedicated overclocking boards also put the 2 DIMM slots as close to the CPU as possible to improve RAM overclocking by shortening the connecting traces (such as the evga z790 kingpin).

I don’t know why the 48GB(2*24GB) are not more popular, If I was buying now, I would get one of them. OC’s DDR5 range seems limited and expensive compared to other places.
 
This is the exact set though i've seen a set rated for upto 7200mhz thats meant to be really good.

If i can get upto 7000mhz that would be a treat! Probably have to wait for 14th gen for that though with a more mature MC.

The 48gb kits seem to be quite abit more expensive and timings don't seem to be as tight, unless im reading it wrong.

Prices are all over the place and the 48/96 GB kits tend to be higher frequency kits. I was going to get a 96GB kit, the price jumped £100 in a day so did not bother. Also, most kits are XMP, but AMD kits are slowly starting to show up. Hopefully better kits will appear soon.
 
I don’t see the point of 48GB when you can get 64GB for around the same price. Two strips is generally the better option and requirements only go up. 16GB used to be enough, now 32GB seems to be the new 16GB norm. Obviously depends on what your doing with your pc.

I agree, the 64GB kits have dropped in price a lot. That said the 48GB kits are single rank so work the same as the 2*16GB kits (same number of chips). The 64GB kits have 2 * the ranks so it’s harder to get stable at higher frequencies (2 * the ranks could be a little faster though, like with DDR4). Samsung has now done 32Gb dies so we may get single rank 64GB kits but probably not for a long time.
