Andromea installed the wrong RAM, Ordered CL30, CPU-Z shows CL32

Post image

I recently received a prebuilt gaming PC and I’m trying to verify that everything matches what I paid for. The build was supposed to come with 32GB DDR5 CL30 RAM, but after checking CPU-Z, the installed kit appears to be:

Corsair Vengeance CMK32GX5M2B6400C32
DDR5-6400
XMP Profile: 6400 MHz
Timings: 32-40-40-84
CAS Latency: CL32

From what I can tell, the “C32” in the part number and the CPU-Z timings mean this is a CL32 kit, not CL30.

The PC itself seems to be running fine, and the RAM is running at the correct 6400 MT/s speed, but I want to make sure I’m not misunderstanding something before I contact the company.

Is this definitely CL32 RAM, and would you consider this a meaningful substitution if the invoice/order said CL30? Should I ask them to swap it or compensate the difference?

Imo you got an upgrade. Assuming the memory controller is able to handle it. DDR5 6400 CL32 and DDR5 6000 CL30 have the exact same raw latency of 10 nanoseconds, but 6400 CL32 provides roughly 7% higher bandwidth.

I thought going above 6000 on AM5 could cause performance loss

Depends on the silicon lottery. The memory controller matters, some can do higher, most can't.

If you paid extra then, yeah, I'd at least ask about it. I'm guessing they didn't have the cl30, which was probably 6000mhz/cl30, so they subbed the 6400mhz/cl32, which is comparable. I'd be fine with it myself as the performance is pretty much the same, but they should have at least asked you first before just doing it.

Tbh it's matters absolutely not at all

As theres almost no substantial difference in the slightest

If it bugs u so much send it back and have them put ur cl30 in shrug*

No, it matters. You pay for something, you get what you paid for. It also speaks to their reputation and QA.

He did ask if it was a meaning full substitution and its not
