Hey everyone! I recently upgraded my RAM from 64GB to 128GB, and I'm seeing some pretty disappointing benchmark results. I know that UserBenchmark may not be the ideal tool for this, but I also got a low score with PC Mark 10. I made sure all my RAM sticks are the same brand and model, and my motherboard supports the memory frequencies. My setup is as follows: MSI MPG B550 Gaming Plus motherboard, AMD Ryzen 7 5700X CPU, AMD RX 7800-XT GPU, and 4 sticks of Corsair Vengeance RGB Pro 3200MHz RAM with Windows 11 as my OS.
Before the upgrade, my UserBenchmark score was [this](https://www.userbenchmark.com/UserRun/70617114), but after adding the new sticks, I got [this result](https://www.userbenchmark.com/UserRun/70657008) with no significant changes whether XMP was on or off. PC Mark 10 gave me a really low score of [this](https://www.3dmark.com/pcm10/137534419), suggesting that my setup is performing worse than a typical office laptop. I did get better read speeds and latency with AIDA64 Extreme, but I'm still puzzled about what's going on. I haven't tried removing the new sticks to retest yet, but I plan to do that soon. Any ideas on what could be causing these weird results?

Your benchmark scores largely depend on more than just RAM capacity. UserBenchmarks can be a bit misleading since they might favor certain CPUs. The increase in RAM won’t significantly enhance tasks if your CPU is the bottleneck, and 128GB might be overkill for your needs. Plus, if you have RAM with different voltages or timings, that could also hinder performance. Just keep in mind that speed and latency matter as much as capacity!
It's possible you're running into issues with having 4 RAM sticks installed. The CPU might be having a harder time managing the increased memory due to the extra slots. Just because you've got more RAM doesn't automatically mean better performance—the CPU still handles everything. You're not only storing more data now, but the CPU has to keep track of more memory slots, potentially slowing things down. Also, make sure you’ve installed your RAM sticks correctly in dual channel. If they’re not in the right slots, that can affect performance too!
Definitely check the slots! If you have the first set in slots 1 and 3, then the new ones should go in 2 and 4. And don’t forget to peek at your BIOS settings—sometimes adjusting settings can help bring out the speeds you expect!
Have you tried disabling and then re-enabling XMP/DOCP in the BIOS? It might help. Also, keep in mind that switching to 4 sticks could potentially change your RAM timing from 1T to 2T, which could impact your benchmarks slightly. And seriously, why do you need 128GB? Just curious!
Did you check that your motherboard officially supports 128GB? Sometimes there can be unannounced limitations in terms of memory compatible with certain setups. Rebooting and adjusting your BIOS settings might also help—you'd be surprised how often just toggling XMP settings can yield better results.
Totally! You should look for RAM with lower latency if you want to improve performance. For your setup, RAM with a speed of around 3600MHz could be a better match.
