Searching for the Memory Holy Grail: Part 1by Wesley Fink on July 27, 2003 11:13 PM EST

It wasn’t long ago that we were talking about whether DDR400 would even become an official standard. Now, with the Intel 875/865 chipsets, we see DDR400 completely legitimized. More importantly, with the excellent performance of the Intel Pentium 4 800FSB chips, we are seeing enthusiasts actively searching for memory that can perform at DDR466/DDR500 and even higher speeds. These were memory speeds that we never thought we would be talking about on the way to DDRII, and apparently, memory manufacturers have also been caught by surprise. Introductions have been slow because chips are apparently unavailable, but we now see high-end memory manufacturers scrambling to bring out these extremely high-speed memory modules for which enthusiasts are asking.
Given this climate, we decided to take a closer look at the question of what is the best memory for the Canterwood and Springdale chipsets. In Part 1, we will try to determine the best Memory configuration for the 875/865. We were able to examine this and find some answers with Memory that we had on-hand. The answers will be important for many of you who are looking to buy memory for the new boards, so we decided to release the results of our memory configuration testing. Part 2 will investigate the performance of the new DDR466 and DDR500 modules that will be coming to market in the near future. Since we are still waiting to receive many of these new modules, or currently have only beta samples of some of the memory, it will be several weeks until Part 2 is posted.
The Best Memory Configuration for 865/875
One of the questions we are often asked is whether a particular motherboard can run with four DIMMs - or at the maximum number of memory slots for the board. Surprisingly, the answer is often ”no”, which is why AnandTech added the process of populating and testing all memory slots to the review procedures. However, with the Intel 875/865 Dual-Channel boards, we are realizing that additional questions need to be raised. Is there a performance difference in two DIMMs vs. four DIMMs? Do single-sided or double-sided DIMMs perform better on Canterwood/Springdale boards? What is the real performance difference in one DIMM, two DIMMs, and four DIMMs?
Answers to all of these questions will lead to determining the best-performing Memory configuration for Intel 875/865 boards. We set out to find the answer to this question, and what we discover may surprise you.
