Question RAM voltage and support ?

[Veinamaa]

I've planned to get a 1,25V CL30 6000mhz kit but it got sold out. The only other avaiable kit with same specs excluding the voltage is the Lexar ( LD5BU016G-R6000GDGA ). It got me thinking how much does the voltage matter. Lexar isn't also listed in the supported ram list on the motherboard's site that I plan to get. It also isn't listed in the amd expo section on the amd's website.

Does the voltage matter at all if both ram sticks would be the same? Will the ram work fine on this board/with this setup?

The motherboard I plan to get:

GIGABYTE B650 AORUS ELITE AX

The cpu:

RYZEN 7 7800X3D

What country are you in, so that we know where you can purchase from?

What is the CAPACITY of the kit, ie, 16GB, 32GB, 64GB, etc. that you wish to get?

What is your budget?

Most DDR5 kits are 1.35v, but it shouldn't matter. If it is a 288 pin DDR5 DIMM and is compatible with a specific motherboard (Based on the motherboard QVL list OR, more importantly, the memory manufacturer compatibility list, which is basically only offered by G.Skill, Corsair and Crucial, although you CAN often find proof of compatibility for a given memory kit model on a specific board by searching for it online as many forum users post proof of compatibility.) then whether the voltage for that kit is 1.1v or 1.4v, or anything in between, it SHOULD not matter.

Yes, you ALWAYS want to buy memory in a matched set or kit where ALL of the memory (DIMMs) that you plan to run come together in ONE kit that have been tested for compatibility with EACH OTHER from the factory. Buying separate DIMMs, even if they are the exact same model, is no guarantee of compatibility.

Please read the section in my memory guide titled "Mixed memory (Or the odd man out)" at the following link, and the whole guide if you so choose.

How To - Troubleshooting problems with PC memory (RAM) and XMP profile configurations

In the beginning, there was......BIOS Before you go ANY further, go to the manufacturer product page for your specific motherboard model AND revision. Revision is an important aspect because for any given motherboard there may be more than one version of that model which will be identified...

This is the list I'm planning to get. My budget is around 12 k PLN but it's already heavily stretched. I'm from Poland and I wanna get the whole pc from one place so I can have it assembled there.

The planned capacity of the kit is 2x16GB (32GB total)

Most RAM manufacturers quote two voltages for their DIMMs.

The first (slightly lower) voltage is when the memory is running at the standard JEDEC speed.

The second (slightly higher) voltage is when the memory is running an XMP overclock profile.

Hence, you might see 1.20V at DDR5 4800MT/s and 1.35V at 6000MT/s.

When you raise the memory clock speed, it's often necessary to increase the supply voltage to maintain stability.

Some people choose to overclock RAM even faster than the highest XMP speed and manually increase the memory voltage still higher.

Eventually a point is reached where too much voltage significantly shortens the life of the RAM, or in extreme cases, excess manual over-voltage settings can destroy the memory chips.

Not just "often", almost certainly, if it's outside the JEDEC or natively supported parameters. The rest, and even that for the most part, totally correct.

Well, to start with I'm pretty damn sure that memory won't work because it is ECC (Error correction checking) memory and that board only supports non-ECC DDR5 DIMMs based on the specifications listed on the product page.

Any idea if this ram would be fine?

IR-6000D564L30S/32GDC

(GOODRAM 32GB (2x16GB) 6000MHz CL30 IRDM BLACK V SILVER)​

That is ECC memory as well.
