Crucial CUDIMM 64GB, DDR5-6400, CL52-52-52

3 are the main takeaways of this review, first that CUDIMM modules (and perhaps even CAMM2 if developers can resolve certain scaling issues) are the future, second that CUDIMM modules are plug and play when used with compatible motherboards (no need to enter BIOS to select a profile) and third that as you manually up clocks timings increase alongside them. Also I need to point out two things, first that from the next CUDIMM review such kits will have their own charts (different systems so not quite fair to have both UDIMM and CUDIMM in the same charts) and second that I’ll be using the Core 9 Ultra 285k system at stock settings meaning no overclocking like I do with the 13900k system (should allow for easier comparison of my results with that of anyone else’s – not to mention I may be swapping motherboards soon). Going back to the RAM at hand it’s a bit strange to see Crucial/Micron release a CUDIMM kit running at just 6400MHz and even though you can up clocks or reduce timings (too much room for that due to low stock voltage) the lack of heatspreaders will not let you get away with a lot (I strongly recommend using them at stock settings). Just before the end of the year the 32GB DDR5 6400MHz CL52 CUDIMM kit by Crucial (CT2K16G64C52CU5) retails for USD169.99/195.55Euros directly from Crucial a price tag which although balanced will probably seem like a lot to some people (based on stock clocks). I also tend to agree and so although the very first CUDIMM kit by Crucial performs well it’s not what people looking for a CUDIMM kit will look for, not just based on stock clocks but also the lack of heatspreaders. If however, you don’t care about those things and are able to find this kit for less then I do suggest giving it a shot, it might just surprise you.
