When you're considering PC component upgrades, the first question isn't "which part is better?"-it's "which part solves the problem you actually have?" The four parts here show that split clearly. On one side, you have a $14.40 pair of vintage memory modules designed for older PCs or samplers. On the other, a $151.99 hi-res PCIe sound card built for desktop audio and gaming. In the middle, a Kingston memory expansion board for Compaq SystemPro/DeskPro systems and an NHB 108 DIY upgrade module for hobbyist builds.
Quick take
- Need legacy memory for an older PC or sampler? The Nanya memory pair is the lowest-priced vintage option here.
- Need to expand a Compaq SystemPro or DeskPro? The Kingston KTC-9160/8 expansion board targets that platform.
- Working on a general DIY computer project? The NHB 108 module is a flexible, general-purpose add-on.
- After high-res audio in a desktop? The hi-res PCIe sound card is the audio-first option.

2 Vintage Nanya 72-Pin SIMM RAM 60ns Memory Module
If your target system is built around 72-pin SIMM memory, the Nanya pair is the most direct and lowest-priced entry point on this list. The listing describes two used, 60ns EDO RAM modules in that form factor, and the title's "Legacy PC/Sampler Upgrade" makes the intended use clear. That also points to the limitation: used vintage memory is a hobbyist part, and the description says it is sold as-is. If you are restoring a sampler or retro desktop, the low price and the matching 72-pin/60ns description make this a reasonable starting part. The trade-off is that vintage parts like this are sold as-is, so it is best treated as a restoration or hobby purchase.
Vintage Kingston KTC-9160/8 Memory Expansion Board
This board is the most specific memory upgrade in the group. The title calls out the Compaq 129160-001 SystemPro connection, and the description says it is a third-party equivalent to a Compaq proprietary memory card for SystemPro/LT and select DeskPro 386/486 systems. It also has onboard memory modules plus empty 72-pin SIMM expansion slots, so it is more than a single stick replacement. At the higher end of the memory prices, the extra cost comes with a much narrower platform focus. The description notes that the card is untested and sold as-is, so the practical limitation is that this is really a restoration project buy.
NHB 108 Computer Ultimatedly Upgrade Module
When you don't have a specific proprietary connector or a vintage socket to fill, the NHB 108 is the open-ended option. It is listed as new and is described as a module for DIY computer projects, with wide compatibility across systems and use in home offices, gaming setups, or professional workstations. It is also a low-cost part among these four, which makes it easy to fold into a spare build. The limitation is in the listing details: the model and type are both given as "See description," so the module doesn't have the same easily documented identity as the Nanya pair or the Kingston board. You can still use it as a project part, but the loose spec sheet means it is better suited to experimentation than to a carefully documented restoration.
Hi-Res PCIe Sound Card
If audio quality is the point of your upgrade, this sound card is the only product here built for that task. The description calls out discrete 7.1-channel analog output, SPDIF, headset outputs, mic-in, and line-in, plus 32-bit/384 kHz playback and a 120 dB signal-to-noise ratio. It is listed as new and as an internal sound card, so it fits an audio-focused desktop build. The obvious trade-off is the price: it is the most expensive item in this set, which makes sense mainly if you want discrete surround sound and cleaner audio rather than relying on a motherboard's built-in chip. For a gaming or home-theater PC, it's the most purpose-built choice here.
Final recommendation by use case
- For a low-cost vintage memory start, choose the Nanya memory pair.
- For a Compaq SystemPro or DeskPro project, choose the Kingston KTC-9160/8 expansion board.
- For a general DIY computer build, pick the NHB 108 module.
- For high-res surround audio in a desktop, go with the Hi-Res PCIe Sound Card.
The real decision is about matching the upgrade to your hardware. The Nanya memory modules and Kingston board speak to older systems; the NHB 108 is a flexible project part; the sound card is the clear audio-focused upgrade. Let that distinction guide your choice.
