OCZ PC4400 Dual-Channel Kit
OCZ also provides a matched pair of 512MB DIMMs in their Dual-Channel Kit.
OCZ packaging is virtually identical to Corsair packaging. The OCZ website calls the matched pairs "Dual-Channel Kits". Heatspreaders on the OCZ PC4400 were copper-colored.
OCZ PC4400 Dual-Channel Kit Specifications
| OCZ PC4400 Dual-Channel Kit Memory Specifications | |
| Number of DIMMs & Banks | 2 DS |
| DIMM Size Total Memory |
512 Mb 1 GB |
| Rated Timings | 3-4-4-8 |
| Rated Voltage | 2.70V |
We confirmed that the SPD timings to be set at 3-4-4-8 at DDR550. OCZ states that the DDR550 parts are tested to work with the Asus P4C800 or the DFI LAN Party 875B. Testing is performed on an Asus P4C800 motherboard before packaging. For DDR550 memory, OCZ is using Hynix Revision C-D5 memory chips.

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 !

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.
