RAM recommendations with the Ryzen 7 5800X3D – Article in progress

We were the first to upload information and a review of the processor AMD Ryzen 7 5800X3D (using RAM DDR4-3200C14 4x8GB) by not having been bound under any NDA or having obtained the sample illicitly. Today we have what I have been working on in the last few days and that is to test how to scale different RAM kits with the new processor AMD Ryzen 7 5800X3D.

The launch of the processor has been a great success, but we still have criticism of its launch price and consideration for users who are about to build a new PC, who, by buying the platform, will no longer have access to future improvements.

It was 4 It will require a new motherboard, although current liquid coolers that support AM4 will also support the new socket AM5.

Our first results will be using 720p resolution, because the bottleneck (or stress) goes to the processor, not the graphics card. In a few hours we will also have results in 1080p, but it won't really add much value information (for reference only).

Let's hope for Monday, or Tuesday at the latest (because they still haven't brought the kit that we expected today, Saturday) to have results on how the new AMD gaming processor scales, with low-frequency 2x8GB kits, to difference from those we have tested today.

Also found is the data that we use with the Intel Core i9-12900K/KF processor with unlimited power limiting.

Summary – Getting the most out of Ryzen 7 5800X3D doesn't cost that much

We have yet to prove what penalty we get from using a 2 DIMM configuration, as most reviewers use 2x16GB or 4x8GB to compare processors and video cards. A setting of 2 DIMMs (2x8GB) will be more common.

We will also see in the following days how it scales with a configuration of 2 DIMMs with 3200C14 (XMP) since I have that RAM on hand.

In short, while there is an improvement using more expensive kits and manual overclocking (3800C14 with manual timings) really the improvement is minimal with a configuration of 4 DIMMs. This is the opposite of what was seen with manual OC with the original release of processors using It was 3.

I think it will be more interesting to see in the following days, how much performance impact there is using 2 DIMMs y rams slower. The 3D V-CACHE it's leveraging the improvement one sees in gaming with AMD's new processor.

This is speculation, but also frequency/IPC is another factor that we don't see scaled up with manual RAM overclocking. There could be better scaling with overclock via BCLK + RAM OC, but that would be more focused on the enthusiastic public.

The good news so far is that if you use a kit of 4 DIMMs 3200C14 get very good performance with Ryzen 7 5800X3D.

We will be updating this note with more results (2 DIMM setup and lower frequency RAMs) with our gaming benchmark.
