DDR4Įach 64-bit rank of DDR5 memory (a rank being a subset of memory chips on a memory module) is divided into two 32-bit ranks, with the latency benefits described in that same overview article being applied in a slightly different way. But there’s more to it than that! How We Tested: DDR5 vs. You'd think that JEDEC ( the industry group that standardizes DRAM) would have at least waited for its memory makers to get DDR5-4800 down to CAS 36 just to stay on track with its previous efforts.
But that just means that DDR5-4800 CAS 40 can only be as quick as DDR4-2400 CAS 20, which would in turn still be laggier than the slowest DDR4-2400 at CAS 18.

Of course, the latency situation for DDR5 isn’t as dire as that big number appears at first blush: Latency is specified in clock cycles, so that anything that cycles twice as fast requires half as much time per clock cycle, as outlined in our overview of how to buy the right RAM. Lower numbers, all things being equal, are better when you're talking about latency figures for memory. (Higher-data-rate DDR5 RAM has been announced, but good luck finding any at this writing!) With DDR4 CAS latencies below 20 in high-performing DDR4 memory, that "CAS 40" might sound concerning. Scalpers were even getting in on the proceedings.) And while we expect industry-standard DDR5 to eventually reach data rates as high as DDR5-6400, what’s currently available is DDR5-4800, with a sluggish-sounding CAS latency rating of 40. (Indeed, DDR5 of any kind, period, was scarce at this writing in late November 2021. Why is that? For starters, hardly any high-end (overclocked), performance-grade DDR5 has come available yet.

The only positive i see for gaming is when you have 2x8 you have room to upgrade when you need itĪ lot of laptops i have come with only 1x8GB of SODIMM memory, leaving one slot for upgradability, if your laptop has this, then you can just find the exact same model of the other RAM you already have, make sure its the same speeds, timings, all that stuff There is no difference really in games if you use 2x8 or 4x4 he has a laptop, so it probably uses SODIMM memoryĪ lot of people think that when a motherboard supports dual-channel it can only support 2 RAM stick overallīut motherboards can come with two dual-channels (which is why they have 4 slots), it can have 2 memory sticks in one dual-channel and 2 memory sticks in the other dual-channel But it would be better to buy 8GB DIMM to make all RAM dual-channel.
