I have some questions about your upcoming 128GB RAM setup for the 5950x.
I have some questions about your upcoming 128GB RAM setup for the 5950x.
Hey there, I just invested $600 NZD in two units of G.SKILL Ripjaws V Series 64GB DDR4 (specs: CL18 - 1.35v - 18-22-22-42) from the link you shared. I’m curious if running this at maximum speed with my 5950X is safe. Have others tried this before? The machine is built to handle a lot, but I was thinking about pushing it hard while I was feeling energetic. I’ve got some notes on my PC configuration via builds.gg and hope you can help me understand the risks. Thanks for any advice!
Expect it to function properly. In the unlikely event, you might need to access the BIOS and reduce the RAM speed to 3200 MHz. Alternatively, you could adjust the timings slightly—such as 18-24-24-50—and pick a middle frequency. The official spec states that for dual-channel dual-rank sticks (like your 32 GB units), the highest guaranteed XMP frequency is 3466 MHz. It could run smoothly at 3600 MHz, but may not work with memory slots supporting DDR4 1866/2133/2400/2667/2800/2933/3000/3066/3200 or higher speeds. By JEDEC standards, it backs up to 3200 MHz, while A-XMP OC MODE 1DPC supports up to 4400 MHz and 3866 MHz. The architecture allows non-ECC UDIMM, ECC UDIMM, and un-buffered memory.
I'll provide her with a toot using OCCT and then share the results.
They don't share all the details—this setup works with just two sticks, but Ryzen can be quite challenging with four. It's also important to remember that the 5950x isn't ideal for gaming, especially in my experience; unless you have a specific need, a 5800X3D would likely perform better. Many games I play saw noticeable improvements in stability when switching from a 5950X to a 7800X3D, which probably would have done the same with a 5800X3D. It'll be fun to see if the upcoming Windows update that boosts Ryzen performance actually makes a difference for the 5950X in games.
Absolutely, that's a clear point. The terms refer to specific configurations—either one DIMM per channel or two DIMMs per channel. It seems there might be ambiguity about whether it means only one channel is active or if multiple channels can share the same setup. To get a better understanding, I recommend reviewing the QVL lists and checking how many sticks were tested with four in total, along with the frequencies observed.
It could be true, but in practice it's not that straightforward. Using a dual-rank stick in one socket is similar to having two single-rank sticks in different sockets on the same channel, except the second one is more likely to encounter problems. With four dual-rank sticks across all sockets, it feels like you're dealing with four DIMMs per channel, which raises the risk of training complications and forces manual adjustments to speed and timing.
