RAM upgrade

[Curtis vincent]

Any advice on kits of Ram to go for. Want the fastest but best value for money kit of White/silver DDR5 at least 6000mhz with no more than CL34. I do a lot of gaming but my PC is also for work (3d artist) Currently have 64gb of cheap DDR5 4800mhz CL38 Rest of the system is multiple NVME ssds a custom cooled 12900k and a 4090 for context. I suppose my only other question would be how much benefit would I really get from an upgrade. I do a lot of 3d modelling with high density meshes in Blender, Maya and zbrush. but also want the best performance when gaming. I run the alienware QD oled 3440x1440 ultrawide for context.

G.Skill Trident Z5 RGB Series 32GB (2 x 16GB) 288-Pin SDRAM DDR5 6000 (PC5-48000) CL30-40-40-96 1.35V Dual Channel Desktop Memory Model F5-6000J3040F16GA2-TZ5RS (Metallic Silver)
Seen this for about 130
or same but twice the capacity for 235

But I'm open to better deals if anyone knows anything​

I don't think it is worth it.

Guru3d did a scaling article here and TPU did one here, for your type of workload (blender), the difference between 4800 and 6000 appears to be less than 1.5%.

Puget's more in-depth article suggests the same conclusion:

While increasing DDR5 memory frequency does positively affect performance on both the Intel i9-13900K and AMD Ryzen 9 7950X, the overall gains were relatively small, especially as the frequency was raised beyond the maximum supported memory frequencies of the processors. As we observed above, going outside those frequencies resulted in an overall performance gain of just 5-7%, with the most benefit to our Unreal Engine benchmarks and virtually none to our Rendering benchmarks.

I suspect you could easily overclock your cheap DDR5 to at least 5600 by copying the settings of legit 5600 memory, especially if you just do it temporarily for testing purposes.

Overclocking the ram is something I have thought about tbh. Just not very experienced and generally because of my work I tend to favour stability over slightly more performance. but if you reckon that might be possible then no harm giving it a go.

Should be pretty easy, here is one of buildzoid's videos on the subject:

Quick overclock of a 2x16GB Crucial DDR5 4800 CL40 kit to 5500 CL38

Summary:The dimms are single rank 16GB based on Micron 16Gb rev.A x8 ICs.The ICs are temperature sensitive. This isn't really a problem before 1.4V.5400 38-4...

Giving it a go might put your mind at rest that it's not worth it, but if you value stability then I'd just leave it be, Puget also made this point in their article, since you'd be overclocking both the CPU and the memory beyond spec:

However, the tradeoff for that increased performance is the potential for decreased system stability. In our experience, attempting to push higher frequencies and lower timings can result in a higher likelihood of Windows BSODs and applications crashing. A great example is what we saw when using the DDR5-6400 RAM on AMD. Although we have seen others use that fast of memory – you can even buy AMD EXPO kits for it – we couldn’t get it to work while running any content creation applications. While this is acceptable for many enthusiasts, as they are more willing to tinker with timings and voltages to get to a point of sufficient stability, as workstation manufacturers, it is not something we can endorse right now if you need your system to be a reliable part of your workflow.

What this testing has solidified for us is that if you are looking for the best mix of performance and stability, using RAM that matches the CPU manufacturer’s specifications is probably the right way to go. And to be clear, we are talking about the officially supported RAM speeds, not any of their “optimized for best performance” recommendations.
