512Mb 266MHz DDR RAM memory module, DDR266 PC2100 rating. 184 pins, non-ECC, 2.5V, suitable for the majority of desktop computers designed for 266MHz memory. Double-sided with 16 chips, rated CL2.5-3-3. Lifetime warranty.
The DDR266 module for desktop is a double data rate module composed of CMOS Double Data Rate SDRAMs in TSOP-II 400mil 66pin package and one 2Kbit EEPROM in 8pin TSSOP(TSOP) package on a 184pin glass–epoxy printed circuit board.
DDR266 is a dual in-line memory module and is intended for mounting onto 184-pins edge connector sockets. Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on both edges of DQS. Range of operating frequencies, programmable latencies and burst lengths allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
Features:
- DLL aligns DQ and DQS transition with CK transition
- Double-data-rate architecture
- Bi-directional data strobe (DQS)
- Differential clock inputs(CK and /CK)
- Auto refresh and self refresh
- 8192 refresh cycles / 64ms
- Power supply: VDD, VDDQ: 2.7V+/-0.1V
- Programmable Burst length (2,4,8)
- Serial Presence Detect with EEPROM

Replace memory and added another and now the old PC works at an acceptable speed again. Memory makers must love Norton as it was taking all the resources.

Truly Amazing
Whacked two of these into a Dell that was struggling badly to cope with everyday tasks, and it's like a brand new machine now.
