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.

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/15199/eng/D875PBZ_TechProdSpec.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/images/i875_round_up/chaintech/i875_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.

Hello Paul,

The chip was referenced so many times as i875 in my search, I came to
believe that it was an improvement of some sort. In fact I ran across an
online store offering the board as having the "i875" chip,
http://cgi.ebay.com/ws/eBayISAPI.dl...99633&ssPageName=STRK:MEWAX:IT#ht_2036wt_1138 .
Here's the "Canterwood" reference,
http://cgi.ebay.com/ws/eBayISAPI.dl...001204&ssPageName=STRK:MEWAX:IT#ht_3216wt_904 .
In the second example, the board is described as "Intel D875PBZ - Gateway
Canterwood Bonanza ATX Motherboard" which added to my confusion.
Particularly the "Gateway" part as sub-manufacturer. I thought Gateway might
have made some alteration to fit their specific platform. Luckily, as you
say, the only real difference I've noticed is the 875 was offered with or
without onboard audio. Fortunately, the both of these offerings have the
audio option installed. I just wish the i/o shield backplate was included
with them. Price wise, they are more than appealing.

You help me immensely with a prior post, and again with this one.

Thank you so very much.


Curt.

Dumb question: If the problem is bloated 'lytics, why not just replace them
with good ones or find someone who can do it for you? 'Lytics are simple to
change out.

HTH,
