I'm currently building a PC with a budget of around $650, excluding parts I already own. I've encountered a compatibility warning that's got me puzzled. My setup includes the Patriot Viper Venom 32 GB (2 x 16 GB) DDR5-7200 CL34 memory, which operates at 1.45 V. However, this voltage exceeds the recommended maximum of 1.35 V for my AMD Zen 4 CPU by a small margin. The warning suggests that the RAM might either run slower to comply with the voltage or might need to exceed the recommended voltage limit. I made an edit to clarify that I was confusing the AM5 platform with Zen 5, and I was only checking the RAM compatibility with the motherboard. Here's a breakdown of my current build: [PCPartPicker Part List](https://pcpartpicker.com/list/DwYrdb)

The warning you’re seeing isn’t a glitch! It indicates that the voltage your RAM needs could potentially harm your CPU. Keep in mind that the Ryzen 7600X may not even be able to handle the RAM's maximum speeds because its memory controller could be a bottleneck. It might be wise to save some cash and pick slower RAM that operates at a lower voltage but has stable rated speeds instead.
You might not get that RAM to run at its full speed due to the voltage issues. It could default to 4800 or 5200 MHz, and you may need to adjust the timings manually to reach those higher speeds. Most users find 6000 MHz CL30 RAM to be more reliable and stable, so consider that as an option.

Your RAM speed is pretty high, and with Ryzen CPUs, it can be hit or miss. Overclocking to 7200 MHz might require extra voltage, which is why the warning popped up. To be sure it's compatible, check the motherboard's QVL for RAM list. The only surefire way to know is to test it out since you've already purchased everything. Just give it a shot and see how it goes!
Would it be better to return the RAM for this option? [PCPartPicker Part List](https://pcpartpicker.com/list/FvFtPJ)
No worries, it should work fine as long as you're running the latest BIOS. I would suggest dialing the RAM speeds down to 6000 MHz and tweaking the timings to something like CL30 or CL28 for better performance. I can send you some tuning suggestions if you want!
I'll think about your tips! With age, I've become less patient about running performance. Meanwhile, check out this RAM swap — is it a better option? [PCPartPicker Part List](https://pcpartpicker.com/list/FvFtPJ)
Oh, I see now! I confused AM5 with Zen 5. Would this RAM be a smarter option? [PCPartPicker Part List](https://pcpartpicker.com/list/FvFtPJ)
