Intel D875PBZ Motherboard...i875 Chipset
Hello Again,
As you can tell from the subject header, my question relates to Intel Legacy boards. My Intel D865PERL board finally died, (several bulging/leaking capacitors), on me after a long and useful service life. The hardware and peripherals used on it are still solid. In wanting to maintain as similar a system to the 865PERL as possible, I've run across the D875PBZ board that appears to exist in 2 versions...the 875 and the i875 chipset. I've googled, gone to the Intel site and read many forum threads about the D875PBZ. For the life of me I cannot figure if there are any significant differences between the 875 and i875 chips. I'm assuming, (yeah, yeah I know what they say about assuming), the i875 chip is superior here. If the 875PBZ was state-of-the-art today, and other than being the latest/greatest what would make you choose the i875 chipset over it's brother, the 875? Hardware and peripherals: p4 3ghz HT cpu 1 250gb sata hd 1 500gb sata hd 1 1tb external hd 21/2gb pc3200 ddr memory ati 9200 128mb vid-card hp 2009m monitor 2 sata optical drives 1 external optical drive lexmark x4650 all-in-one 1 rocketfish 5.1 sound card 1 front panel floppy/media card reader 1 pci add-in card for sata optical drives 1 pci add-in card for front panel floppy/media card reader 4 120mm case fans 430 watt psu OS will be XP updated to SP3. Any and all thoughts are welcomed. Thanks, Curt. |

Any and all thoughts are welcomed. Thanks, Curt. First of all, there is only one 875. (See 875P Canterwood, here.) http://en.wikipedia.org/wiki/List_of_Intel_chipsets I see only one board listed here, in this list. http://www.intel.com/p/en_US/support/dsktpboards The technical product spec gives more details. The LAN chip connects to the CSA bus on the Northbridge, so this is the "high performance" configuration. The alternative way to build in LAN support, is to connect a LAN chip to PCI on the Southbridge. The 875P is unique, in providing a second bus suited to a CSA LAN chip. http://downloadmirror.intel.com/1519...chProdSpec.pdf Page 15 shows the block diagram. 82547EI is a CSA bus equipped Ethernet chip. CSA is the second hub bus that runs at 266MB/sec. The 82547EI can do gigabit Ethernet in both directions at 1 gbit/sec at the same time. That is "full duplex". The 266MB/sec bus interface is what makes that possible. Full duplex means file transfer at 125MB/sec in both directions at the same time, using 250MB/sec of the 266MB/sec available (or there abouts). The only "option" I see in that TechProdSpec, is to remove the built-in audio. I wish each option had an exact part number, so you'd know. ******* Intel has used the letter "I" as an icon on the chip. Here you can see Canterwood, as the thing with "82875P" and the letter "I" on it. http://hothardware.com/reviews/image...75_chipset.jpg With Intel, the letter on the end, helps indicate whether there is a GPU inside the Northbridge. For example, 865G would be a chip with built-in graphics GPU. 865P was the version which got graphics via the AGP slot, and the customer buying an AGP card. 875p on the other hand, only comes in one form, and always requires the customer to buy a graphics card. Up to AGP8X is supported by that family, for the AGP slot. If there is some subtle difference here, I couldn't find it. I have a P4C800-E Deluxe here, which would be very similar to your D875PBZ, and the ICH5R still hasn't blown up on mine. Paul |

'Lytics are simple to change out. HTH, Twayne` |
