IBM System x3100 M4

(1) MHz only measures microprocessor internal clock speed, not application performance. Many factors affect application performance.
(2) GB equals one billion bytes when referring to hard drive capacity; accessible capacity may be less.
(3) For models with AMD-K6®/2 processors, installed memory in excess of 128MB will not derive performance enhancements from the included external cache. This note not applicable to Network Station systems.
(4) Variable read rate. Actual playback speed will vary and is often less than the maximum possible.
(5) x2 and V.90 modems are designed to be capable of receiving at up to 56kbps with compatible phone line and server equipment, and transmitting at up to 31.2 kbps. K56 Flex modems are designed to be capable of receiving data at up to 56Kbps from a K56 Flex compatible service provider, and transmitting data at up to 28.8Kbps. Public networks currently limit download speeds to about 53kbps. Actual speeds vary and are often less than the maximum.
(6) Battery life results are based on BAPCo's (Business Applications Performance Corporation) SYSmark benchmark test. Battery life will vary based on many factors including screen brightness, applications, features, battery conditioning, power management and other customer preferences.
(7) For ThinkPad systems, weight includes battery and travel cover; actual weight may vary due to manufacturing process, vendor components, and options.
