Silicon Power DDR5 64GB (2x32GB) Zenith RGB 6000MHz (PC5-48000) 288-pin CL30 1.35V UDIMM Desktop Memory Module RAM SP064GXLWU60AFDH White

I had to exchange for the RGB version, however...These sticks are so worth the money! Plug and play, easy to get setup. Blazing fast! PC runs soo much better now! Increased the stability of my Framerates, games run so smooth now!

Fairly certain these are A-die dual rank since there are chips on each side of the pcb. I did not take off the heat spreader to inspect the chips. Upon seeing a decently priced 64gb kit with good timings at 1.35v I assumed these must be some of the newer A-die that are also being sold at cl26/1.45v, and as far as I can tell I was correct in that assumption. My used 7700x did not like going anywhere above 2000 on the FCLK "infinity fabric clock", either a weak memory controller or it's too hard to push dual rank that high in general.The memory had zero issues running at 6200 or 6400 but without the infinity clock going higher it's just better to run them at 6000 and see what you can do to lower the timings. It's tough finding overclocking examples of dual rank, I did manage to find a good video but it was on the older manufactured chips that require far more voltage.Nonetheless these chips took some decently fast but safe timings and perform flawlessly at 1.435v @6000 cl26. I can't guarantee it will stay that way but they have passed all stability tests with no errors so far. Attached pictures should show the safe timings. A few voltages do not show up and it incorrectly reports these as SR "single rank" but the same program identified them as DR "dual rank" until it stopped displaying some voltages. The MEM VDD is 1.435, MEM VDDQ 1.435, and CPU VDDIO 1.410 even though it displays closer to 1.435v from the sensor readings, the others report as 1.44v so they are fairly close to set voltages. Everything below CPU VDDIO on the right column is on auto, this is what memory guru "Actually Hardcore Overclocking" advised for dual rank A-die. VSOC was not happy unless I left it on Auto voltage.At 175 bucks these are a great value over buying advertised cl26 @6000 kits that cost up to twice as much for 64gb of DDR5.

After 6 months, functionality remains great. So far, memory quality can compete with more expensive other brands. Don't know yet how long memory will last.

i made the mistake of relying on pcpartpicker to confirm my cpu:mobo:ram would work together, but it turned out that since my mobo supports multiple series of cpu, only the 8000 series works with this ram, and i was building a 7000 series pc, so i had to return these well made fair price sticks, then spend $30 more on nearly the same timing only because my mobo maker database confirmed it working with my cpu.something else i noticed due to all the sensitive timing issues on DDR5 mobos is these sticks must work in pairs, so if one fails you won't get half the ram, you'll get no ram posting at all. other sticks can run alone so check with your mobo maker on what they support should this be a future trouble shooting concern for you. i also noticed if your mobo has 4 stick slots, don't count on adding 2 more sticks in the future - that may not work ever, or at least until further firmware updates or mobo revisions. bottom line is triple check your ram choice before checking out.one odd thing i noticed in this listing is "Supports overclocking with Intel XMP 3.0 and AMD EXPO" which according to Gigabyte is not true, all Silicon Power sticks are XPM and no stick I have ever seen supports both clock/voltage management standards, so AMD pc builders may want to quadruple check with on what cpu:mobo you use before you buy this.

Very happy with the RAM for my AM5 Ryzen 7700 setup!

Super low CL rate + 6400mhz + clean aesthetics + smooth RGB and all packed in the lowest bang for buck 64gb package. These are perfection!

Not much more to say. 100% confident the RAM died because memtest86 said so and tested it in multiple machines. The RAM lasted less than 24 hours in a brand new build before it kicked the bucket. I read here in other reviews that it does not work well in AMD machines, so count this as a second recommendation to avoid this RAM for an AMD machine.

Works great right out of the box with my 9800X3D on a Gigabyte X870I AORUS PRO ICE motherboard. I'm running the kit with the default 30-38-38-96 EXPO timings at 1.25v and everything's stable. I'm pretty sure I could tighten the timings up more than I already have too. The RGB works nicely with SignalRGB and OpenRGB too.
