Kancept<p>So, I decided to max the RAM out on my <a href="https://infosec.exchange/tags/Lenovo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Lenovo</span></a> <a href="https://infosec.exchange/tags/Thinkstation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Thinkstation</span></a> <a href="https://infosec.exchange/tags/P340" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>P340</span></a>. It takes 128GB of RAM. It gets here, I install it, machine just turns off and on. I troubleshoot, and if I pull the ram from DIMM slot 4, it boots fine. Not a bad stick as I rotate through them and they all test fine. I reinstall the original ram (2x 16GB sticks) and I notice the same slot is bad. </p><p>Call in to get warranty work, get the mobo swapped, same issue. 🤔 While the tech is on the phone to get another mobo on the way, I get some idea that maybe it's an allocation issue since it's happening during POST- you know- like the old <a href="https://infosec.exchange/tags/BeOS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>BeOS</span></a> >1GB RAM issue. I pull my 3.2TB Samsung PCIe AIC NVME and 💥, machine boots and posts all ram- including DIMM slot 4. I try my NVME in another slot and same issue. 😓</p><p>So, weird issue- I can't have a PCIe AIC NVME (or at least this one anyway) and have all 4 ram slots work in a Lenovo ThinkStation P340 tower system. You'd think for a workstation-class machine, this wouldn't be an issue. But here we are. 128GB of RAM or an additional 3.2TB of screamin fast PCIe NVME server-class storage. 😐</p>
