Let’s start by looking at a 16GB 4800MHz DDR5 kit from Crucial. Yes, you heard me correctly; 4800MHz and 2x8GB DIMMs. Clearly, wallet-friendliness is a priority here.
That 4800MHz rated speed runs via XMP, though we don’t get EXPO operation for the AMD platform. Timings are 40-39-39-77 at a very healthy 1.1V.
The 16GB set is 2x8GB. That’s pretty unusual for DDR5 given that the individual ICs we commonly see are 16Gb per chip. What that means is that Crucial is running four ICs per DIMM, instead of the usual eight or sixteen.
I guess we could possibly think of this configuration as half-rank, instead of single-rank or dual-rank, in completely oversimplified, unscientific layman’s terms.
Given that these sticks are Crucial branded, the underlying ICs are from the Micron stable. And they look to be A-die ICs.
Styling is about as basic as it comes, and that’s fine given the priority of cost over flashiness. You get the ICs mounted on a simple black PCB that features a sticker purely for product categorisation. The height is that of a standard DDR5 PCB, so there’s no worry for CPU cooler interference.
Evidently, there is no heatspreader for the 4 chips per DIMM. But that is probably fine given the 1.1V operating voltage; excess heat should not really be a concern, and the included temperature sensor will help validate that point.
Pricing for Crucial’s 2x8GB DDR5-4800MHz kit is currently low-to-mid £60 on Amazon, depending on which discount is applied for the day you check.
That’s reasonable given that faster-clocked 2x8GB DDR5 kits tend to cost £75 or more. And some of the more affordable 2x16GB kits are in the region of £130+.
