What is current sweetspot for DDR5

[oxrufiioxo]

Issues are like bugs found by the community. I think AMD has certain design and people expectations are different.

I think it has more to do with people being use to intel and being able to run all kinds of janky combinations.... I ran 8+4, sticks with different speeds/timmings, different brands all without issues on intel. With Zen you have to be a bit more smart about what you pair it with and ideally it has a docp/expo profile otherwise you are at the motherboards mercy. I think also for whatever reason there is less validation with AMD. Honestly though I've done countless AM4/AM5 builds without even looking at the QVL and haven't had any what I would call major issues. I did a lot of memory tuning on AM4 it was honestly really easy, easier than on intel in my book anyways with subtimings etc. I do stick with Bdie almost exclusively on AM4 and 6000CL30 on AM5 so that has probably helped alot. To be fair the last 2 intel systems a 9900k and 10700k had terrible IMC and the asus boards I had both kinda sucked a Z390 Code and a Z490 Hero.

- Making use of 200 GB allocated to a 2 TB PCIe 5.0 SSD, alleviating the cost of DDR5 memory, thus allowing fast data flow back and forth on the motherboard, taking advantage of the benefits of pairing DDR5 with a high-performance PCIe 5.0 SSD
- Knowing that a high-end PC game can use more than 100 GB of data, and Windows 11 alone uses 60 GB, the strategy of using a "virtual DDR 5 memory" on the SSD could solve the high costs of DDR 5 and its memory usage for heavy applications, perhaps creating a new problem generated by the lack of a bottleneck in the PCIe 5.0 interface, even though it is twice the speed of the previous generation...

Friends don't let friends buy Corsair RAM.

Honestly it's my go to whenever I build a system for someone (which is rare now) because it simply works out of the package. I've never had to RMA one of their kits, used to have this issue with both OCZ and Crucial.

That said, isn't a sweet spot almost unique for each individual based on budget, performance need, other hardware, and timeline of use and future upgrades.

It is one of my go to brands too, has been for years for the same reason - I have never had a stick of Corsair RAM fail.

No, not even the fastest PCIe Gen 5 SSD currently available is 10% as fast as DDR5 system memory. RAM sticks remain relatively inexpensive, so your best option is still to buy enough for your needs to be met. 32 GB should be adequate for gaming PCs, 64 if you are a power user megatasking - more RAM is only necessary if you have specific usage patterns for it

The OPs first post is full of inaccuracies regarding memory manufacturers/companies. I don't have the energy to go through the whole thread to see if they were corrected but I'll assume our guy ir_cow straightened him out

Thanks, will add this to pile of inaccurate information I've dispersed on various other hardware.

Old reply but for me it's about history. For all the time I've been into computers Zen is the first time I couldn't just buy whatever was cheapest and just plop it in. I did that on the 2600x (2x8GB G-skills something 3000Mhz something) and over some months they would slowly corrupt Windows and eventually it wouldn't even boot until I reinstalled. Downclocked to 2400Mhz and everything was fine. I have never been much into RAM stuff (because "good" RAM has always been expensive and that money was always better to spend on faster CPU or GPU, or more RAM) and it has never been a problem until Zen.

Price wise it's simple just buy the cheapest a-die kit you can find clock & it to your CPU's capabilities which probably covers 99% of the use cases. On AMD you've severe bus speed and ratio limitations making high speeds irrelevant so 6000-6400 with timings as low as possible is the way to go. On intel it's probably ~7200 on 4slot boards and 7600 on 2 slot boards ( -other than i9's- you proly cant find imc's capable of 8000+)

The only kit I ever had issues with and I'm not alone was corsair LPX which wouldn't even boot with one stick... That was with first and ryzen+ only though 3000/5000 worked without issues.... My go to was 3200 CL14 and then just manually tuning it however I wanted I never found a single 3200 CL14 kit that didn't work on Ryzen 2000-5000. I even have some 4000 low latency kits that work fine at 3800 on 5000 that are meant for intel.

I never cheap out on RAM on any platform at least not over the last 15 years. Although comically DDR5 might have been the cheapest kits I've ever purchased with 2 32GB 6000 CL30 kits costing my like 110 each...
