The Fastest, The Hardest: DDR533 From Geil
PC4200 is coming to the desktop... with horrible timings...
Memory companies continue to push the speeds of their modules higher and higher following the requests of computer hardware enthusiasts. GeIL recently announced the fastest DDR SDRAM devices ever running at 533MHz, speed meant to be achieved by DDR-II SDRAM memory only in 9 months time.
GeIL, a well-known company among overclockers and hardware enthusiasts positions its latest addictions to the Dual Channel Ultra Platinum Series of memory-module kits for use with dual-channel systems by power users community.
Both new versions of the GeIL Ultra Platinum Series products use 3.5ns memory chips, 6-layers PCBs and are equipped with copper heat-spreaders and may work at 2.6V ~ 2.95V voltage. The difference between the so-called PC4200 and PC4000 modules is just speed and timings: DDR500 modules use CAS2.5 7-4-4 timings, whereas DDR533 devices boast with CAS3 8-4-4 timings.
Memory kits are available in 512 and 1GB versions and come in retail package with neon green clear acrylic case and instructions. Do not expect them to be inexpensive, I should add.

At FSB400 (200mhz - PC3200) each cycle is 5ns
Cas2.0 is 10ns
Cas2.5 is 12.5ns
Cas3.0 is 15ns
Pick your FSB and scale accordingly
FSB533 (266.5mhz = 3.75ns) PC4200
Cas3 = 11.25
FSB500 (250mhz = 4.00ns) PC4000
Cas2.5 = 10ns
Acutally not that bad considering the Bandwidth.....
This is why: (from a review of this memory)
Realistically timings aren't as significant as that much bloody bandwidth!
Im not saying tight timings are not important but that is a seriously monster clock speed. It's gonna be damn fast whatever!
No memory for an Amd setup though.
... yet..
This kind of memory is semi-immature, give them a few months and lets see what they can come up with
Amd is going "800 fsb" as well in a short time and this type of memory will be needed even for amd users. I do believe this is the end of the DDR. Next step is probably DDR2.
