Choosing a PC components upgrade is less about picking a single winner and more about matching the part to the slot. The four options in this comparison solve different problems: two are legacy memory components, and two are general DIY modules described for computer projects.
Quick Take
The listed prices run from USD 14.40 to USD 74.99, with the 72-pin SIMM pair at the low end and the Kingston expansion board at the high end. If you're restoring a Compaq SystemPro/LT or DeskPro 386/486, the Kingston card is the targeted choice. If you have a free 72-pin SIMM socket in a legacy machine, the Nanya pair targets that slot family and is the lowest-cost item in this group. If you want a new, broadly compatible module for a DIY computer project, the NHB 108 modules sit between them in scope.

Decision Matrix
| Product | Best for | Watch out for |
|---|---|---|
| Vintage Nanya 72-Pin SIMM RAM Pair | Legacy systems with a 72-pin EDO SIMM socket that need a two-module set | Used, vintage hardware described for collectors and hobbyists |
| Vintage Kingston KTC-9160/8 Expansion Board | Compaq SystemPro/LT or DeskPro 386/486 restoration projects | Untested and sold as-is |
| NHB 108 Computer Ultimatedly Upgrade Module | DIY computer builds where a new general-purpose part is enough | Compatibility is described in broad terms |
| NHB-108 Ultimatedly Upgrade Module | A second DIY option with the same general-purpose feature description | Feature description stays general, so it suits flexible builds |
Product Notes
Vintage Nanya 72-Pin SIMM RAM Pair
This listing offers two 72-pin SIMM modules described as 60ns EDO RAM, the sort of memory you'd use in a legacy PC that takes 72-pin EDO sticks or in a vintage sampler looking for an upgrade. The title points the module at legacy PC and sampler use, and the two-module count lets you populate two slots at once or hang on to a spare. The trade-off is that this is used, vintage hardware described as suitable for collectors and hobbyists, so it is not the same as a fresh production part. Choose it when your target device already has a compatible 72-pin slot and a two-module set fits your plan.
Vintage Kingston KTC-9160/8 Expansion Board
This memory expansion board is the most specialized option in the group. The listing and description point it at Compaq SystemPro/LT and DeskPro 386/486 systems, and it is positioned as a third-party equivalent to the Compaq proprietary memory card. It includes onboard memory and open 72-pin SIMM slots for expansion, which makes it a one-card starting point for a restoration build. The caveat comes straight from the listing: the board is untested and sold as-is. For a collector who has a Compaq system waiting for this exact form factor, the Kingston card is the targeted pick.
NHB 108 Computer Ultimatedly Upgrade Module
The NHB 108 module is a new, China-origin add-on described as an upgrade module for DIY computer projects and widely used across systems. It is aimed at someone who is building or customizing a computer and wants a general-purpose part rather than a vintage memory module. The listing says the module is reliable, durable, and precise, so the pitch is about all-around upgrade use. The limitation is that the description expresses compatibility in broad terms, so it is best thought of as a flexible DIY experiment rather than a drop-in part for a specified board.
NHB-108 Ultimatedly Upgrade Module
The NHB-108 listing carries the same general-purpose feature description as its NHB 108 counterpart: a new module for DIY computer projects, described as precise, reliable, durable, and broadly compatible. If the exact model wording of the listing is the difference you care about, this is the alternative. It is equally useful for a custom computer project where you are not trying to match one specific socket. The practical limitation is also the same: the compatibility wording remains general, so treat it as a module for exploration and customization. Between the two NHB listings, choose the one whose wording you prefer, since their detailed descriptions match.
Final Recommendation by Use Case
- Restoring a Compaq SystemPro/LT or DeskPro 386/486: go with the Vintage Kingston KTC-9160/8 Expansion Board because it is made for that proprietary memory expansion role. Keep in mind that it is untested and sold as-is.
- Upgrading a legacy PC or sampler with 72-pin SIMM sockets: pick the Vintage Nanya 72-Pin SIMM RAM Pair for a two-module set with the right vintage form factor.
- Building a DIY computer project and want a new, general-purpose upgrade part: the NHB 108 Computer Ultimatedly Upgrade Module and the NHB-108 Ultimatedly Upgrade Module are close options. Use the one whose listing description you prefer; both are described for broad compatibility.
