Projects

memholder

So far, this project has been a success and a great learning experience.

On October 17, for the x48 DIMM and SODIMM version, I added another set of two posts in the middle of the long side to offer more support given the weight of hundreds of memory modules. This six-post version would be mechanically compatible with the existing four-post version though for deployment at 2nd Life Inc, the current memholders may have to be swapped out. The existing ones would be used at home instead, where there it is not expected to be potentially thousands of memory modules stacked on top of each other.

On October 18, 2025, entering yet another day of trying to get the Raise3D N2 printer at Build RVA to print memholder designs within the same or less amount of time than the Ender 3 V2. I have spent about US$65 on a 0.6mm and 0.8mm nozzle for the Raise3D N2 printer and installed the 0.6mm nozzle on the left extruder. As time and bed adhesion remained persistent issues, I eventually decided to cut my losses and went back to printing these out on the Ender 3 V2 as time and money is ever tight.

After the panel swap in the Samsung Chromebook described in the following section, the Chromebook took place of the X200 Tablet as the 3D printer controller for now.

On Saturday, October 18, I received an Innolux N116BCA-EA1 Rev.C2 to take place of the N116BCA-EA1 Rev.C1 that has light spots on screen. There was a noticeable improvement with this Rev.C2 variant over the Rev.C1. I plan on using the left over N116BCA-EA1 Rev.C1 in an external monitor, possibly revisiting MonitorCow with a monitor small enough where I can reasonbly 3D print the case instead of trying to carve out a case from MDF like I did with the larger, 15.6", MonitorCow MNC-N156KME-GNA from 2024 that never got finished.

Integration of memholder into 2nd Life Inc. has been highly successful, increasing storage density and preventing damage to memory modules.

As with Windows 10's support discontinuing the next day, I asked if I can put Linux on the work PC at my workbench. Later on, my supervisor gave me permission to install a Linux distribution onto the work PC. Before installing Fedora, I removed the hard drive that was in there before, preserving the Windows 10 installation along with all of the files, and put in a Micron 1100 2.5" SSD along with two 8GB DDR3-1600 modules with Micron D9RVX ICs. After that, I installed Fedora 42 onto the PC.

I worked on finalizing the setup of Fedora on the work PC,

When sorting through laptop DDR3, I found a set of Kingston SODIMMs from 2012 with Hynix H5TQ2G83CFR-PBC ICs that have an XMP profile for DDR3-1866. I found this interesting as that few laptops from the time had XMP support and that this was extended to SODIMMs in the first place.

After getting a set of DDR3 SODIMM-DIMM adapters after the success with using the DDR4 ones, I was able to test DDR3 SODIMMs in a desktop that has an ASUS 970 PRO GAMING/AURA and AMD FX-8350. It turns out that this motherboard is quite good for memory overclocking.

I do not have much information about what I did during this day but I continued to work on memory testing.

Friday, October 17

While waiting on memory testing, I worked on inspecting some monitors that just came in within the previous days. Among the monitors was a ViewSonic VG2439M-LED. At first I thought this monitor was going to have an Innolux MVA panel like the more recent counterparts but it had a TN panel; a Chimei Innolux M236HGE-L20 Rev. C3. This so far has been the best TN panel I have ever seen, looking more like MVA, AAS or another IPS/VA technology. After noticing this, I immediately offered to purchase this unit and I brought it home this day. The monitor took place of the VG2249 that I temporarily set up in the lab so I can return the VG2249 to its rightful spot on my desktop upstairs.

In laptop scrap, looking for any RAM, SSDs and displays, I found a bright blue HP Stream laptop that I found interesting as it had a SODIMM slot on board but with soldered eMMC storage. I later found out this is common for low-end laptops of this time (2018).
