Ryzen 3000 Memory System Explained (Buildzoid)

Simply put, don't break dual channel memory, especially with 3rd gen Ryzen, because you'd basically be cutting performance in half, even if you aren't using the APUs.

Even if you're on a budget, just run 2x4 and get another 2x4 later.

Yep and Buildzoid always does interesting videos even if he a bit obsessed with VRMs, no, make that a lot obsessed lol. You have to take into consideration that Buildzoid is always looking at things from an over-clockers perspective, if you're not going to overclock your system with every last tweak then the VRM aspect is not as important to you. Also VRMs are less important if you're just going to throw a 6-core onto the motherboard with 2 sticks of ram and never upgrade it beyond that. I wouldn't pay > £110ish for a motherboard because money spent elsewhere will get you much better performance increases and I'm not much interested in over-clocking beyond setting XMP and maybe trying to set CAS 1 or 2 lower.

Dual channel is a rule for any modern PC anyway. If people go single channel - welp.

[MrL0G1C]

Thankfully this mostly applies to DDR4, I still have DDR3 in my system and it's only running single channel because the mobo has a faulty memory slot (found out way too late) :-(

Morale of the story, test all memory slots when you buy your mobo.

I also have a faulty slot. Screw ASUS.
Now, what come to tests - they're full of ♥♥♥♥. They ran memory at 2400MHz, no wonder it didn't show that much of a difference. Typical DDR3 user runs it at 1333/1600MHz, and the performance difference is just as significant as with DDR4.

I have been saying this stuff for a while already. The memory controllers in Ryzen CPUs are garbage.

Everyone else: "Just get dual channel 2x4GB now, you can add another 2x4GB later."

[Bad 💀 Motha]

2x8gb is not that expensive.
Buy that and be done with ever adding ram to that PC.

If you are a pro needs user then obviously you should increase your budget and save up more so you can go with 2x16gb minimum if your work apps benefit from having alot of ram.

[Omega]

Yeah, 16GB is $80 now. Dirt cheap compared to what it was 1-2 years ago.

[Malygos]

I mean you can get 3600mhz cl16 for like $150 ram is cheaper than its ever been and since ryzen benefits so much from it why go single channel at all? I have a hard time seeing anyone buying these new chips running 2 4gb sticks unless its with the 3600.

[Bad 💀 Motha]

Cause 3000 or 3200 is just fine and not ridiculously priced

Most people buying $350-$500 cpus built for multithreaded workloads arent worried about an extra $50 for the performance gains. https://www.techpowerup.com/review/amd-zen-2-memory-performance-scaling-benchmark/4.html

Some games beneifit as much as 5 fps from 3000 to 3600mhz excepct better in cpu heavy apps

[Bad 💀 Motha]

That's fine for a 3900X
But it won't make much difference on a 3600 or 3700X, especially if that buyer is trying to keep costs down a bit if possible.

Except it does i can get measurable differences on my 3700x going from 3000 to 3466 people spending $350+ on a cpu arent sweating $50 more for ram i know because im one of them

It's not really necessary to spend more on the best RAM you can get unless you have the budget, in which case you'd have a Ryzen 9. 3200 CL14 Flare X is pretty affordable and enough for most, and it can overclock pretty nicely on a good board.
