AI Appraisal Estimate

A pair of legacy desktop computer memory modules consisting of green printed circuit boards (PCBs) populated with black integrated circuit chips. The module on the right features a prominent Micron (MT) logo with a white label indicating a 128MB capacity and PC133 speed specification. It also bears an HP inventory label with part number 220114-001, suggesting it was originally pulled from an HP business desktop or server. The module on the left is a similar SDRAM stick with a 'Made in Taiwan' label and exposed black memory chips from various manufacturers. Both units feature standard gold-plated contact fingers at the base for insertion into a motherboard's DIMM slots. These modules date back to the late 1990s to early 2000s, a period characterized by the transition from SIMM to higher-speed DIMM formats. Externally, the units show minor signs of handling and some dust, but the gold contacts appear relatively clean with no significant oxidation or deep scoring. The PCBs are intact with no visible cracks or evidence of thermal damage. While obsolete for modern computing, they represent a specific era of semiconductor manufacturing and system integration by major OEMs like Micron and HP.

I have examined the provided description and visual data for the pair of legacy SDRAM modules, consisting of one Micron/HP 128MB PC133 stick and one generic Taiwan-manufactured unit. Visually, the modules appear to be in good physical condition; the gold-plated contact fingers show minimal wear, suggesting low insertion cycles, and the lack of scoring or oxidation is positive. The PCBs show no signs of electrolyte leakage or thermal blistering, consistent with standard office-environment retired hardware. The market for PC133 SDRAM is currently bifurcated. While these components are obsolete for modern productivity, there is a steady 'niche' demand within the retro-computing community for building period-correct Pentium III or early Pentium 4 systems. The Micron/HP branded module carries a slight premium due to the reliability associated with the MT chips and official OEM part numbers (220114-001). However, as 128MB was a common capacity, these are not considered rare. Comparables on secondary markets like eBay show individual 128MB PC133 sticks selling for $5 to $12 depending on the brand. As a pair, the value is primarily utility-based rather than collectible. Limitations: This appraisal is based strictly on visual inspection. While the modules appear authentic, I cannot verify functional integrity or presence of 'bit rot' without a POST (Power-On Self-Test) using a compatible vintage motherboard and MemTest86+ diagnostic software. Further, I cannot confirm the integrity of the traces under the labels. To provide a definitive valuation, I would need to perform a physical stress test and verify that the SPD (Serial Presence Detect) data on the EEPROM chip matches the physical labels.
