Router

From my experiences, the following router model share the similar memory chip specification. Therefore, most of the time memory chip from one model is interchangeable with another.

1. DRAM

* 800 series prior to 850/870 series; SOHO 90 series; 1700 series; 2600XM series; 2650 & 2651 - 100 Pin DIMM, SDRAM, 125MHz/133MHz, Unbuffered, Non-parity, 8ns, 3.3V, 16Meg x 32

* 800 series: 870 series - (provided by bigsy ) 168 pin DIMM low-profile CL3 non-ECC PC 133, i.e. Kingston KVR133X64C3L/128 works (full specification is clickable here), modules that are not low profile will not fit in the case correctly

* 800 ISR series: 880 series - (provided by jmbronk ) 512MB PC2 4200 SODIMM, i.e. Samsung PC2-4200S-444-12-A works

* 2600 series (excluding XM models and the 2650, 2651, and 2691) - 100 Pin DIMM, EDO, 60ns

* All 1800 routers EXCEPT 1841 - 200 Pin SODIMM, SDRAM, 266MHz DDR, Non-ECC CL2.5 e.g. Kingston KVR266X64SC25/256

* 1841 - 144 Pin SODIMM, SDRAM, 133MHz, Non-ECC CL3 e.g. Kingston KVR133X64SC3/256

* 2811/21/51 - (provided by kamikatze from this post) ECC DDR266/333/400 DDR. Kingston do a 512MB upgrade - KCS-D2800/512

* 3825/45 - (provided by kamikatze ) DDR333 or higher with ECC and at least CL2.5 (@333MHz). Kingston do 256MB & 512MB upgrades - KCS-D3825/256 & KCS-D3825/512

2. Flash

* 800, 820
* 2500; 2600 (2610, 2611, 2612, 2613, 2620, 2621, 2650, 2651); 3600; 4000 (4000/4000M, 4500/4500M, 4700/4700M)
* All 2600XM models
