Ram Recommendation

[deflorence]

Which DDR5 32G Ram from the Overclockers shop do you recommend, Oh you great experts? (I will get 2 of them in order to have 64G).
I have the TUF Gaming B650-Plus Wifi mobo, Ryzen 7 7700 B-Core Processor, Win 11 Pro.
My main use is content creation/video editing.
I currently have the stock 2 x Corsair 16384 4800Mhz with Expo Tweaked set at DDR5-4800MgHz.
Merci!

This is not recommended with DDR5, I'd get 32x2 instead (or 2x48).

Getting 2 x 32 is what I intend to do, apologies if my initial post was not clear about this-The Overclockers shop list of DDR 5 Ram is: 5200 MHz, 5600 MHz, 6000 MHz, 6200+ MHz & 7200+ MHz. Given my mobo & my needs, which are recommended?

Oh right, the recommended speed is 6000, preferably C30, e.g.

My basket at OcUK:

• 1 x Corsair Vengeance EXPO 64GB (2X32GB) DDR5 PC5-48000C30 6000MHz Dual Channel (SKU: MEM-CRS-02841) = £179.99
• 1 x G.Skill Trident Z5 Neo EXPO 64GB (2x32GB) DDR5 PC5-48000C30 6000MHz Dual Channel Kit - B (SKU: MEM-GSK-01361) = £229.99

Total: £417.97 (includes delivery: £7.99)​

6200 or 6400 is sometimes possible to run (depends on the CPU's memory controller), but not something I'd do myself, especially since you plan to run dual rank sticks.

To run higher speeds than 6200-6400 you will have to run the RAM out of sync and that has a performance loss that needs very high speed memory to compensate. There's an article which talks about that here and the points are similar for your Zen 4 CPU, as for Zen 5:

DDR5 Memory Performance Scaling with AMD Zen 5

Our AMD Zen 5 Memory Scaling Review examines six different DDR5 memory speeds, including DDR5-8000, DDR5-6400 1:1, DDR5-6400 CL28 and others. We looked into how these speeds impact performance in gaming at four resolutions and a wide range of application workloads.

With most workloads, the performance loss below 6000 is not that big, so if you can find a great deal on a slower kit (e.g. there's been some big deals on Crucial Pro kits lately), I wouldn't worry.

Impact of DDR5 Speed on Content Creation Performance (2023 update)

DDR5 memory has kits rated for up to 8400 Mbps, while desktop CPUs only officially support up to 5600 Mbps. How much does running at official specifications actually impact performance in common content creation applications?

Merci. So the upper limit (in my case) seems to be 6000Mhz. Useful to know, and thanks for the Puget System article.

I think I'll go for the G.Skill Ripjaws M5 (2x32GB) as the CAS numbers look good (CAS 28-36-36-96), and there is a lifetime warranty. I'll decide over the w/e-When rendering videos lasting 1 to 3 hours and with complex special effects, any minute you can shave off the total rendering time is a godsend, as FX are done by the CPU, so there is a lot of shuffling of your video material between memory & CPU.

Personally, I wouldn't. Reason being, from what I can see they're nearly £100 more expensive than a cheap C30 kit and you can never 100% guarantee that any memory overclock will play nicely with your CPU/motherboard, which would be very frustrating if you just paid top dosh for a premium part, but just "meh, whatever" if you cheaped out.
