Performance Test Configuration
The Memory testbed for evaluating the Corsair XMS4400v1.1 and OCZ PC4400 is the same used in our earlier reviews of DDR500 and other High-Speed Memory.OCZ PC3700 Gold Rev. 2: The Universal Soldier
OCZ 4200EL: Tops in Memory Performance
Mushkin PC4000 High Performance: DDR500 PLUS
Corsair TwinX1024-4000 PRO: Improving DDR500 Performance
Mushkin & Adata: 2 for the Fast-Timings Lane
Searching for the Memory Holy Grail - Part 2
All test conditions were as close as possible to those in our earlier memory reviews.

Since both Corsair and OCZ target their DDR550 memory at the Intel 875/865 enthusiast, we only tested on our Intel test bed.
Test Settings
The following settings were tested with Corsair XMS4400v1.1 and OCZ PC4400:- 800FSB/DDR400 - the highest stock speed supported on 875/865 motherboards.
- 1000FSB/DDR500 - the specified rating of the majority of recent memory modules that we have tested.
- 1066FSB/DDR533 - the maximum speed that many current Intel 865/875 boards can achieve. This value was also tested because it provides 3.2GHz speed at 12x266, which is a useful comparison to standard Intel 3.2GHz performance.
- 1100FSB/DDR550 - the specified rating of the test memory modules.
- Highest Stable Overclock - the highest settings we could achieve with this memory and other memory we have tested.

Nice results at 5:4 vs 1:1 ... See, I told you so, after reading one of your older Ram articles from a few months back... 5:4 2-2-2 beats 1:1 2.5-4-4-8 anyday =)I'm glad you tested it !

holy tiny target market, batman!how many people require memory to run at 275fsb default?

Very good memory article once again Wesley. I dont know where this 'low latency memory doesnt make any difference' argument started but from my observations, it is false. OCZ usually test on an ABIT IC7 so I wonder why it did't make the grade on the DDR550?Any hints as to when DDR500@ 2-2-2-5 is going to become reality. It seems like the old BH5s are still the lowest latency mem. chips and they've been around for a year now. 1:1 at low latencies and PAT aggressive is the way to go. That's why I run my 2.6c at 2.8 even though it goes stable to 3.3 but then I got to run the mem. at 5:4 (no PAT) and performance improvement is barely noticeable.
