2GB DDR2-800 RAM Sourcing Guide for Industrial & Legacy PCs

The phrase "2gb ram ddr pc800" refers to two distinct legacy technologies, with the current market predominantly revolving around DDR2-800 (PC2-6400) rather than the much rarer PC800 RDRAM. * DDR2-800 (PC2-6400): This is the most common interpretation. It operates at 800MHz with a bandwidth of 6.4 GB/s. As of 2026, it is physically and electrically incompatible with modern DDR4/DDR5 motherboards and is primarily used for maintaining industrial systems or legacy PCs WikipediaAlibabaMade-In-China. MODEL. LAPTOP DDR2 2GB. CAPACITY. 2GB. Memory Speed. PC2-6400S 800MHZ. Memory Socket: SO-DIMM. RAM COMPATIBLE. Work with all brand motherboard. Chipset. ...

Kingston makes it quick and easy to select compatible RAM memory for your Desktop PC, Laptop, or Server. ... At PC800 speeds that i850E chipset of mine would accept 64 RDRAM devices total, 32 per channel. * Pricing Trends: In 2026, prices are influenced by a broader memory "Supercycle." Increased demand for AI-related HBM and DDR5 has reduced overall legacy production capacity, causing stable but slightly elevated pricing for older standards BacloudNewegg. B2B listings show that DDR2-800 modules are highly accessible, while PC800 RDRAM shows zero active large-scale wholesale availability, confirming its status as an ultra-niche collector's item.

RDRAM - Wikipedia

Because of more complex interface circuitry and increased number of memory banks, RDRAM die size was larger than that of contemporary SDRAM chips, resulting in a 10–20% price premium at 16 Mbit densities (adding about a 5% penalty at 64 Mbit). Note that the most common RDRAM densities are 128 Mbit and 256 Mbit. PC-800 RDRAM operated with a latency of 45 ns, more than that of other SDRAM varieties of the time. In 2001, benchmarks pointed out that single-channel DDR266 SDRAM modules could closely match dual-channel 800 MHz RDRAM in everyday applications. In November 1996, Rambus entered into a development and license contract with Intel. Intel announced that it would only support the Rambus memory interface for its microprocessors and had been granted rights to purchase one million shares of Rambus' stock at $10 per share. To achieve RDRAM's 800 MHz clock rate, the memory module runs on a 16-bit bus instead of a 64-bit bus in contemporary SDRAM DIMM. RDRAM was also up to four times more expensive than PC-133 SDRAM due to a combination of higher manufacturing costs and high license fees. PC-2100 DDR SDRAM, introduced in 2000, operated with a clock rate of 133 MHz and delivered 2100 MB/s over a 64-bit bus using a 184-pin DIMM form factor. With the introduction of the Intel 840 (Pentium III), Intel 850 (Pentium 4), Intel 860 (Pentium 4 Xeon) chipsets, Intel added support for dual-channel PC-800 RDRAM, doubling bandwidth to 3200 MB/s by increasing the bus width to 32 bits. Rambus DRAM (RDRAM), and its successors Concurrent Rambus DRAM (CRDRAM) and Direct Rambus DRAM (DRDRAM), are types of synchronous dynamic random-access memory (SDRAM) developed by Rambus from the 1990s through to the early 2000s. The third generation of Rambus DRAM, DRDRAM was replaced by XDR DRAM.

RDRAM NooB: What is the diff between PC-600, PC-800, PC-1066 etc....

The previous poster has all the info you need about P4 fsb (RDRAM naming is quite straightforward while DDR you have to memorize or get out a calculator): PC600 - 300mhz (600 MHz effective hence the name PC600) PC800 - 400mhz (800 MHz effective) PC1066 - 533mhz (1066 MHz effective) PC1200 - 600mhz (1200 MHz effective) Thus a 400 MHz fsb P4 matches the best with PC800 since both run at 400 MHz. Memory speed is arbitrary to FSB. PC2700 DDR SDRam operates at 166FSB because a lot of users choose to run at a 1:1 ratio to the FSB. RDRam boards usually have 3X or 4X multipliers. Meaning if you run at 100FSB and use 4X, you would get 400Mhz or PC800. At 133Mhz, 3X is 400Mhz and 4X is 533Mhz (PC1066). RDRam is meant for high performance. TRUE, but some of the boards are very inexpensive and the ram is also not that expensive. For example: ComgGeeks has an D850GBA for $20.00 + $9.00 shipping ($29.00) GoogleGear has 128mb PC-800 for $41.00 each shipped (2 for $82.00) NewEgg has Celeron 1.7 P4 (Retail w/HS & Fan) for ($53.00 shipped) Thats $164.00, not bad for this combo, for a woman who will never OC, nor play any games. The PR nomenclature for RDRAM designates the "effective" clock frequency of the RAM modules. RDRAM transmits data on both the rise and fall of the clock cycle (just like DDR-RAM - twice per clock), so a PC-600 module runs at 300mhz actual, and 600mhz effective.
