What windows 98 can do, and what other motherboards can do, I don't know. Anyone who doesn't change their price daily must have enough margin on the modules not to have to do so. Micron full spec. The Crucial modules are well engineered but you're going to pay for it. Price watch is misleading at best.
People charge below cost for modules to get their products listed at the top of the list.
You normally can either buy only one, or the vendor charges you way too much for shipping. Please, companies are just not out to lose money. If they're offering a loss leader, they're going to make it up somewhere else. If demand is good on Monday there will be a trend of a price increase. If the demand is poor, the price increases we've seen over the past few days will slow immediately.
