I welcome bigger kits and from more suppliers, but the specs are disappointing. I built a threadripper machine with 14-14-14-34 memory (64GB) because that is all I could find in stock. I wanted a minimum of 128GB (preferably in 4 sticks), but I'm not willing to destroy the timings to get to 3600MHZ. 16-16-16-36 at that speed would be "acceptable." Otherwise give me a bigger kit at 3200 with my current timings. Those already exist, but I can't find any in stock. Threadripper is not bandwidth starved and my apps are latency sensitive anyway.

You do realize that CL 16 on 3600MHz is nearly identitacl to CL 14 on 3200MHz? That is only for the first 128 bits, after that the 3600 kits destroys the 3200 kit. How often do your CPU fetch that small amount of data?

Of course, and you realize that if the processor is not data starved 3600 does zip over 3200 right? You do understand "latency sensitive apps" - right? I can do the math just like anyone else which is why I'm willing to accept 3600 16-16-16, not 16-20-20-GodKnowsWhat. It is not impossible to build large sticks with the speedier timing and 128GB 3200 14-14-14-34 already exists (but no stock). When larger no compromise kits are available, I don't have a problem opening my wallet to finish this build properly, but as I have latency sensitive apps, I'll wait for what I want. And yes, they fetch tiny amounts of random data at ridiculous speeds. If you have apps the don't make tiny requests, be thankful, any cheap ram module will do.

What software do you have that needs such low latency? Financial, mining, 3D presentation? What CPU do you have, does CPU matter or is just memory the important part? Just wondering.

I'm running a Threadripper 3970x and cpu does matter. The software is looking up 32bit and small fragments in a table of hashes. I have numerous apps with similar needs, including some I've written myself. The size depends on the app, but 32 bits is the large end of the spectrum, 16bits the low end. And no it is not mining, finance or 3D. :)

Aha, even more interesting. Is it security or compression software? I'm a developer, too, so I'm even more curious now what software that is. If you don't want to disclose more details, just point out the most publicly available example of such software, or send PM.
