  • Ordered 4 for a potential future build. Cheers.

    • 4800MHz CL40 DDR5 for future ?

      intel 13th use DDR5 5600 MHz

        Oh shi*

        • It's totally fine. Intel 13th support up to 4800/5600 MTs. Intel. So, you can still use it. However, it will bring 10-20 FPS differences for some games. Link.

          BTW, can someone explain why it's up to 4800/5600? Depends on the specific model?

          • @ChristmasCC: 4800-5600mhz is the jedec range. Anything above will still work with intel+amd. However Intel+amd consider anything above jedec speeds as an overclock+unsupported officially. Yes, activating xmp/expo/docp voids your cpu warranty in intel+amd's eyes, thankfully there's no way for them to ever tell.

            • @JerraJones: Sorry but have no idea what jedec range is. Seems like different voltage? I think what makes me confusing is: "The 13th Generation Intel® Desktop Processors support DDR5 (Up to 4800/5600 MTs) & DDR4 (Up to 3200 MT/s) speeds. While the 12th Generation Intel® Desktop Processors support DDR5 (Up to 4800 MT/s) & DDR4 (Up to 3200 MT/s) speeds." Why the 13th DDR5 has two different up to? The rest only get one?

              • @ChristmasCC: All it means is that 13th gen Intel will "officially" support 5600mhz as well, whereas 12th gen did not. 5600mhz or even 6000mh would work with either CPU, jedec refers to the standard speeds all DDR must meet, and the voltage range it must run at when meeting that speed. i.e. there will not be 5500mhz DDR5 on the market because there is no jedec standard at that speed.

  • so wait, can someone explain why this would not be good for a future proof system? I want to build an AM5 system but the ram prices have been limiting. This is very tempting

      2 kits of the deal RAM = 32GB for $100

      The current AM5 budget king is the $170 32GB Kingston kit here which can be manually tuned around 6000/CL30 to 6400/CL32 depending on your mobo, CPU and luck

      If $70 + tuning time is too much for you, best to get this cheap kit now and then upgrade to a factory 6000+ kit when prices further drop

      Note Samsung have just announced they are cutting DRAM production because of massive oversupply so recent DDR5 price drops are likely to continue only for the next few months

      Really depends on if you are going with the X3D CPUs or regular. For the non-3D CPUs, going with such slow RAM is silly as they lose a tonne of performance while the X3D CPUs lose far less but still pretty notable for the price difference compared to total build cost.

      Note: The difference may be even larger than the video I linked if you tune the sub-timings.

  • How much can you OC this RAM?

    • It doesn't have a heat spreader so i wouldn't overclock it much. The RAM chips have no cooling at all so it could over heat. These aren't designed for overclocking enthusiasts. It's designed for OEM systems where there generally aren't any overclocking done.

      • +2

        Heat isn't an issue, RAM doesn't generate enough heat since DDR3 where voltages were much higher. No DDR4 RAM needs heat spreaders and no DDR5 will need them either, heat spreaders are as useful as a rear spoiler on a Mitsubishi Lancer.

          They look cool though. :P

          Any how there's a guide over at Overclockers on how to overclock DDR5 ram. That might help. Looks like these RAM sticks are at the base DDR5 ram clock of 4800mhz so it should overclock a bit. The RAM sticks were built for OEM systems for stability and not overclocking in mind so you might not get a huge overclock out of it.

          https://www.overclockers.com/ddr5-overclocking-guide/

      • I'm 99% sure heat is not the limiting factor here.

  • Look at the price of the 32GB RAM stick of this it's $173.95. https://www.mwave.com.au/product/crucial-32gb-1x-32gb-ddr5-4…

    Makes 2 x 16GB sticks for $98 from this deal an absolute bargain in comparison to just one 32GB stick.

    • If you're going with amd you're pretty much stuck getting 2x32gb if you need 64gb of ram since 4 sticks of ram is very unstable rn on am5.

      • I wonder if that might be a BIOS issue or if it's a chipset bug.

        How that passes quality assurance is beyond me.

        • Amd early bios isn't known to be great with higher ram speeds, am4 wasn't all too different in its early days where even 2 sticks of decent speed (ie 3200 c14) wouldn't work frequently.

          4 sticks will be fixed eventually undoubtetly, amd's 'cap' of around 6000mhz won't though since the memory controller on 7000 series cpus can't really push much higher.

      • I've got 4x16GB RAM on a 7950X running 5200MHz CL40 (XMP), and it has passed a stability test at 5600MHz CL40 (Manual OC) as well. I don't think there's a huge issue with 4 sticks.

        • 5200 cl40 is very slow speeds and is just jedec spec, equivalent would be ddr4's jedec spec of 3200 c22. If you wanted to push it higher/get amd's recommended spec of 6000mhz you'll have a bad time.

          • @JerraJones: Difference between 5600MHz and 6000MHz is 7%, and price difference between 4x16GB and 2x32GB is 70%, I think that it's still worth it going for the 4 sticks in this case. Anyway this cheap RAM probably won't be able to hit 6000MHz even ignoring CPU memory controller limitations. And personally I would prefer not to push it higher and increase the risk of stability issues, which is why I am using the stock XMP profile.
