Some Neat RcF84 triva facts

1) The ATi A4 for the P4 will have PC2700 aka DDR333 supported.

2) DDR-II isnt QDR

3) Rambus Speeds here to the future
16bit- PC800 400MHz 3200MB/s @ Dual Channel
16bit-PC1066 533MHz 4266MB/s @ Dual Channel
16bit-PC1200 600MHz 4800MB/s @ Dual Channel
32bit-PC1066 533MHz 4266MB/s @ Dual Channel
32bit-PC1220 600MHz 4800MB/s @ Dual Channel
64bit-PC1066 533MHz 8533MB/s @ Quad Channel
64bit-PC1200 600MHz 9600MB/s @ Quad Channel

Rambus 32-bit RIMMs are effectively 32-bits wide, but in reality two 16-bit wide channels are contained on one module, so the chipset still sees it as dual channel. The same is true for 64-bit modules; they use four 16-bit channels on a single module.

5) SDRAM will be at

--DDR--
PC2700(DDR333)-166MHz
2666MB/s @ Single Channel
5333MB/s @ Dual Channel
10666MB/s @ Quad Channel

PC3200(DDR400)-200MHz
3200MB/s @ Single Channel
6400MB/s @ Dual Channel
12800MB/s @ Quad Channel

--QDR--

PC2700(QDR666)-166MHz
5333MB/s @ Single Channel
10666MB/s @ Dual Channel

--DDR-II--

PC4300-266MHz
4266MB/s @ Single Channel
8533MB/s @ Dual Channel
16466MB/s @Quad Channel

PC5400-333MHz
5333MB/s @ single Channel
10666MB/s @ Dual Channel
<font color=red>21333MB/s @ Quad Channel</font color=red>

5) BEDO support was removed from the VIA VP2 datasheet.

6) Even though the VIA VP3 and Apollo Pro chipsets may claim to support DDR SDRAM, this support refers to an older specification of the memory type. These chipsets are not compatible with the current DDR spec.

7)The VIA ProMedia with integrated Trident AGP was renamed to PM601 and was then renamed again to PLE133. And the PM-133 (with S3 AGP) used to be called the ProMedia-II.

8)When using PC133 SDRAM on the VIA Pro133A chipset, only 6 banks may be used. All 8 may be used with PC100 SDRAM.

9)The VIA KT-133E chipset supports the PowerNow! Features of the mobile Athlon/Duron CPUs, though it can still be found in desktop systems.

10)The SiS 645 and 650 chipsets support up to 3GB of PC2100 DDR SDRAM. When using the faster PC2700 (DDR 333) only 2 DIMMs can be used, limiting the chipset to 2GB max mem.

11)The NVidia nForce chipsets differ by what AGP texturing (memory for graphics) configuration they use. Crush 11 uses a 64-bit SMA configuration, sharing main memory with the rest of the system. Crush 12 uses a dual channel DDR configuration (effectively 128-bit) with one channel (a separate dedicated DIMM) used for the onboard graphics memory. If an external AGP card is present the second memory channel can be utilized by the system instead. The same is true for the Crush 17 and 18 chipsets, respectively.

12)The Intel 840 chipset can only support quad CPUs with a 100MHz bus; running quad CPUs on a 133MHz bus is not validated. Dual CPUs on a 133MHz bus is fine, however.

13)The Intel 820 chipset supports D-RDRAM technologies in densities as high as 256Mbit, but SDRAM (via the MTH) is limited to 128Mbit. To achieve 1GB of memory with SDRAM on the i820, <font color=red>Registered SDRAM must be used.</font color=red>

14)The Intel 430NX, 430FX, 430VX, 430HX, and 430TX chipsets do not support write-through mode for the L2 cache.

15)The AMD 762MP northbridge has specific incompatibilities with the VIA VT82C686B southbridge when write-snooping and when using ACPI suspend mode with Registered DIMMs. Note that the 762MP northbridge does not support unbuffered DIMMs.

16)AMD 640AGP chipset was never released.

17)The Shuttle HOT-603 (the only motherboard that shipped with the 640 chipset), uses the 8-bit Tag w/ 1 modified scheme for its 1MB L2, yielding 255MB cacheable in WT mode and 127MB in WB.

19)Intel's 3GIO supports PCI 2.2 cards !!!

22)The Hammer is going to have 200MHz(400MHz) DDR FSB

23)Future Nforce chipsets will have DDR333 support, no intel chipset in future

24)Intel Springdale chipset for the P4 will support DDR-II !!!! The only chipset to date supporting DDR-II.

25)Itatium next chipset is going to be called the i870 using a 100MHz QDR FSB using DDR SDRAM

Thats all

Nice Nvidia and ATi users get a Cookie.... Yummy
