Re: 2 SO DIMM 144 PIN PC100 [64MB] costs only $70 now... Please post the website where you can get 32MB SODIMM's for $35 each. The best prices I see are $55 for 32MB and $75 for 64MB that will work in a Dell notebook. Your logic seems flawed. You claim to have done your homework but obviously have not. First: Assume you can get the "right" SODIMM modules for $35 each... you cant save $130. The 3500 only has 2 SODIMM sockets and comes with a minimum of 32MB. If you buy two modules, what will you do with the third module? Throw it away? The $100 Dell charges is for a single 64MB module, not 2 32MB, this allows you to upgrade to 128MB in the future. So you have 2 choices: 1. Add (1) 32MB with generic SODIMM for an extra $35 and be stuck at 64MB 2. Purchase with 64MB for an extra $100 and have an upgrade path to 128MB Cost delta, $65. Dell's costs for memory are not exorbitant... they are in-line with most on-line sources for reputable manufacturers. There is no "rip-off" as you claim. Sounds like you have a hidden agenda. Second: What type of memory is used in the Inspiron 3500? EDO, BEDO, ECC, parity, 3v, 3.3v etc.? Better be sure to get the right kind. Ever wonder why most memory upgrades advertised by 3d parties are vendor (eg Dell) specific? Third: Although the 3500 does use a 66Mhz memory and FSB, how do you know the system isn't designed to run with PC100 compliant parts? In designing a memory subsystem, there are a variety of tradeoffs that can be made. Faster memory parts spec'd in a slower system allow the designer to reduce costs in other areas: Did you know: 1. EMI can be reduced through heavier termination on signals like address, ras, cas, we and cs. This heavier termination reduces overshoot, ringing and increases flight times. These increased flight times would reduce timing margin with 66Mhz parts whereas the faster TCO's of 100Mhz parts will work fine. 2. Reduced EMI helps speed time to market and reduces the need for excessive chassis shielding. It also helps to gain approval faster for FCC class A/B and international requirements like CISPR. PC100 is not a scam, the chip timings and module layout requirements are tightly controlled. So, make sure you know what you are getting. I'm not saying the Inspiron 3500 requires PC100 compliant parts... I don't know, but if I was planning to upgrade memory myself, I'd surely find out because one oversight and you'll likely flush $50 down the toilet. MEATHEAD
