Verification of 32GB memory upgrade compatibility.
Verification of 32GB memory upgrade compatibility.
I'm using a Ryzen R5 3600 in B450 Mortar max and an RX 5700 XT. My RAM is currently 16GB (two 8GB modules, Kingston KHX3200C16D4/8GX). In some games, memory usage has reached around 14.5-15GB, so I'm weighing the upgrade to 32GB against the cost. DDR4 modules are affordable. I searched for the same RAM but it's no longer in stock, so I'm exploring alternatives. The models I've checked include Kingston KF432C16RBK2/16 and KF432C16BBK2/16 (both 3200 with 16-18-18). They seem similar enough, even if the heatspreader differs. It should work fine, right? If it's not worth the effort, I could opt for two 16GB modules, which would be more expensive. I'm also thinking about getting a 5800X3D later but not right now.
It's advisable to upgrade the path to 2x16GB memory. Older Ryzen chips can sometimes struggle with 4x sticks, though it's unclear if the 3000 series is affected. Generally, increasing RAM to 3600MT/s isn't that costly. If you decide to go with 2x16GB, that should be feasible.
It varies. If you assume XMP will function, it won't. But if you intend to adjust frequency, timing, and stability, then it might be possible.
The AM4 board doesn't support quad channels, but dual channels still work even with four sticks. That's the straightforward answer.
It actually has four sticks, but they’re more likely to cause issues than two. It’s not saying it won’t work, just that swapping both is a better choice than adding extra ones. You also gain a small benefit—being able to use 3600MT RAM.
take a look at the burner screenshot to spot the IC and search for compatible OEM bare PCBs. These often come with exact part numbers that define the IC revision and rank configuration. For example, an 8GB HMA41gu6afr8n should be a 4Gbit dual-rank (double-sided) Hynix AFR, while a 16GB M378A2K43DB1 matches a dual-rank Samsung 8Gbit D die. Ordering the right model guarantees the precise RAM specs and density.
Keep in mind that some affordable RAM options like these can deliver impressive speeds—such as hitting 3400 DDR3 on generic boards—though you’ll need to be flexible with binning. If you’re after top performance (above 3800-4000 DDR4 or even 5000+), consider investing in a higher-end kit.
If OEM bare PCBs matching the same IC aren’t available, opt for budget kits like the 3200C16/3600C18 set. You’ll likely get random revisions and plastic heatspreaders, making it hard to ensure quality. Stick with Hynix or Micron-based sticks (Klevv or Crucial) for better reliability. Unless you’re targeting extreme frequencies, this approach is mostly practical and cost-effective.
You'd need clear specifications to compare the chips accurately. The differences between models like 3600MT CL18 and 3200CL16 aren't always straightforward. Prices vary based on storage size and brand, so a direct comparison isn't always reliable. It's hard to get consistent info across sources, making it tricky to decide without more details.
Some respondents seem eager to manually adjust RAM speed. I haven’t been in that group before; if you need it to function smoothly, investing in the right capacity is better than trying to fix it yourself. If you’re willing to invest four times the recommended sticks, go for it. The main concern is how much time you’re prepared to spend troubleshooting when things don’t go as planned. Not always, a 3200 CL16 chip might support up to 3600MT CL18, but those could be slower variants meant for different uses. The reason faster RAM is worth buying is that manufacturers have validated performance at those speeds and programmed the necessary timings—so XMP/EXPO should work as intended. Pushing slower RAM beyond its rated speed can take hours of timing tweaks or may never run stable faster than the label suggests.
