I already have 2x8GB 3200MHz +_G.Skill Ripjaws V_ DIMMs in my computer which I got to run with my _Ryzen 5 +1600_ at 2933MHz; first generation Ryzen is quite finicky when it comes to +getting some memory to run at higher clock speeds and the XMP profile didn't +work. Usually, you either need to choose RAM that your motherboard vendor has +tested and confirmed to work at certain speeds, or you need to spend some time +tinkering to get the best possible results. + +When I first got this RAM, I tried putting it in my computer but was only able +to get it to run stably at a really low speed, something like one step above +2133MHz. I wasn't willing to make that sacrifice for what I thought at the time +was an unnecessary increase in RAM. However, with me constantly running up +against my computers limits, I decided to give it another go. + +I first tried keeping my settings the same and plugging in the two new modules +into the two available slots on my motherboard. As expected, this failed to +boot. Then, I tried a configuration where the two smaller capacity DIMMs were in +the primary memory slots (A2 and B2) and were the only memory modules in the +system. This, surprisingly, worked without any problems; the modules were +running at 2933MHz and I had a total of 8GB of RAM. + +Then, I reset my memory settings and I put the 16GB modules in the remaining +slots (A1 and B1). The computer booted fine, with 24GB of RAM running at a stock +speed of 2133MHz. Slowly, I increased the speed and upped the voltage until my +motherboard threw a tantrum, beeped loudly at me, and reset my settings. I +landed on 2866MHz at 1.25V but there was an instance where the motherboard +failed to boot, but tried again and succeeded which made me up the voltage to +1.35V hoping that it was just a voltage problem. + +So, as I am writing this, I have 24GB of RAM running at 2866MHz at 1.35V. Slots +A2 and B2 are the _Ripjaws 4_ 4GB DIMMs and slots A1 and B1 are the _Ripjaws V_ +8GB DIMMs. I ran a few stress tests using `stress` and did a memory benchmark +and things looked okay. Except that Firefox tabs keep crashing… and now the +`apt` module in polybar is reporting "a corrupt package file or wrong hash". +Hmm… + +Okay, I'm back! I dropped the speed down to 2800MHz at 1.35V and things seem to +be running stable now. I tried dropping the voltage as well to reduce power +consumption and heat generation but anything below 1.35V was not stable either. + +Despite running the RAM 133MHz slower, there is not a noticeable difference in +the responsiveness of my computer or the performance of my games. Then again, +even if there's something like a 5FPS drop in games, it's worth it for the peace +of mind of not running into OOM situations. I'll see in the coming days if the +current speed is causing instabilities and if I'll have to drop it down even +further (the next lowest mark is 2733MHz) but, for now, I'm just enjoying my +extra 8GB of RAM. + +(If you're wondering, I arrived at a maximum voltage of 1.35V because that's the +voltage the XMP profile set and I didn't want to risk going higher than that.) + +_This is my sixth post for the +[#100DaysToOffload](https://social.paritybit.ca/tags/100DaysToOffload) +challenge.
