Price and rating as shown on Amazon when we collected them. Both change.

The Lexar THOR Z Series OC DDR5 RAM is a 32GB kit (2x16GB) running at 6000 MHz with CL36-40-40-96 timings, and it takes fifth place in this guide. The listing prices it at £424.99 and shows 4.4 out of 5 from 75 ratings, with 71 of those 75 ratings at five stars and 9 at one or two stars.

The awkward part is the timing column. Nine of the ten kits in this guide are 32GB at 6000 MHz, and the cheapest of those — not this one — is £409.99, so the Lexar asks £15 more for the same capacity and the same headline speed while running looser CL36 timings than the CL30 kits around it. The reviews describe other things again: one buyer says they "got them for £300", which is not the £424.99 on the page, and two others describe a single 8GB stick and a 16GB system, while the title and the RAM Size field both say 32GB (2x16GB). Everything on this page is taken from the Amazon listing — we have not tested the memory ourselves.

What buyers actually say

Quoted from customer reviews on Amazon

Verified purchase

“Amazing Ram for the price, got them for £300 so cant complain as regardless of what people say, the price is the price. Been running at 6000mts with no issues.”

Adam Clewes

“I grabbed this single 8GB stick of Lexar DDR5 RAM to throw into a test bench build, and overall it gets the job done for the price. Popping it into the slot was easy, and enabling the XMP profile in the BIOS worked on the first try without any stability hiccups. The aluminum heatsink looks clean and keeps things cool even under load.However, you need to know what you are getting into with single channel memory on DDR5. Running just a single 8GB stick means you miss out on dual channel bandwidth, which can significantly drop your frame rates in modern games and slow down heavy multithreaded tasks. If you are building a primary rig, you really want to grab a matching pair instead of running just one stick.Unlike DDR4 where the power management integrated circuit was on the motherboard, DDR5 actually moves the PMIC right onto the memory stick itself. This helps with power efficiency and direct voltage control, which is why these overclocked modules can push higher speeds cleanly.It is a decent budget stick if you just need something basic to boot up a system, but definetly plan on adding a second stick soon for proper performence.”
