E7501 vs E7505 Anything diff besides AGP?

[LanEVENT]

I am in a very big hurry to get a few servers updated, and I would like to get the E7501 Chipset Mobos, but I am being told by just about everyone that they will not be available for another couple weeks. However the E7505 boards are out, and I can purchase them right now. To me the difference is really that one has an AGP port. Some people have mentioned that the memory controler on the E7501 is better. I am just looking for input. I would hate to prolong my very neccessary server replacements anylonger than I have to, but I would rather have the better product.

Thanks for any input

Here's from Anandtech's Xeon 2.8 DP and 2.0 MP Review (a very good article, and would likely be of interest to you:

Next we have the E7505 chipset, otherwise known as Placer. The role of the 7505 is to basically take the functionality provided by the E7205 and bring it to dual processor Xeon workstations. The specifications of the chipset are the same, the only difference is that these chipsets are validated for dual processor operation and support the 604-pin Xeon DP interface.

Moving onto the server side, Intel is updating their current chipset line with the Plumas-533, now known as the E7501 chipset. The original Plumas chipset (E7500) was the first dual channel DDR solution from Intel and as the name implies, the E7501 simply adds support for the 533MHz FSB and dual channel DDR266.

Just like the E7500, the 7501 does not have an AGP interface (why would you need AGP on a server?) and is strictly a Xeon DP chipset, Pentium 4 owners will have to stick to the E7205 (Granite Bay).

I take this to mean, yes. They are identical except for lack of AGP controller.

If u would like some more assistance, please don't hesitate for email/pm/im me. Jesus is LORD!!!

See thats what I thought as well, and I did catch that article. As I was going around looking for the 7501, I was about to settle on the 7505 just because of time and I was told by several people that it was worth the wait for various reasons. one person even said that the 7505 was not Dual channel, just interleaved, which I thought was odd, but then I went to intels site ( http://www.intel.com/design/chipset...iid=ipp_srvr_proc_xeon+prodi_compare_chipset& ) It mentions that the 7505 is single channel in the memory area - which leads me to be very confused

Hmmm, looking at that chart, I notice that it says not only the E7505 but also the E7500 (which is most certainly a Dual Channel DDR chipset) use single channel. That statement about the E7505 is very confusing. it says it's single channel, but yet it says that memory must be put in as pairs. To be honest, I'm not certain that chart is exactley a reliable thing. It says that the 460GX (on the same row as about the single channel) uses 72-bit wide DDR SDRAM DIMM's, but not only is it an SDRAM chipset, but the chart states right below that row that the 460GX uses PC100 SDRAM.

To go further, I went to the http://www.intel.com/design/chipsets/E7505/ Home page and it says that it has Dual Channel DDR266. My hunch is that Intel has got a few errors on the chart you linked to. I would say that the E7505 is just an E7501 with an AGP controller.
