What's the big difference between 865PE and 875P chipsets?

[donfm]

I'm returning my MSI NEO-LSR motherboard because it is a piece of s**t!!!!!! MSI apparently didn't even test this board before they put it on the market. BIOS stability problems, crashes, poor overclocking ability you name it. Seems my problems are common to this board since others are having the same issues.

I now need another board and wondering what's the deal with the 865PE chipset that seems popular all of a sudden? Thanks in advance?

875P has PAT (performance accelerated technology). The 865PE does not. PAT does make a small difference in overall system performance, however, many doubt this claim since the performance cannot be observed in Sisoftware Sandra unburred memory bandwidth scores. Intel charges a lot for this technology, and it is only available if you are running a P4 "C" chip and DDR 400 speed in dual channel mode. If you change the memory ratio, PAT is disabled, as it is when running B and A P4's.

865PE boards are popular because they are a lot cheaper, and not noticably slower, than the 875P. The 875P is a great chipset, it's just that MSI doesn't make a very good product.

A lot of these boards do have some issues with memory timings, and some people have reported problems getting the Serial ATA to work right (especially when using adapters) but other than that these are fine boards.

If you are still using your 2.4B, I would save my money and get an 845PE board. Less buggy, and the performance will be pretty much the same.

actually the springdale(865) has been noted in test to perform better than the canterwod(875) in non 800mhz chips. but for the 800mhz chips it outperforms the sprindale by quite a bit. the main difference is on board extras. you can get canterwood boards with alot more of the xtra sh!t that you want.

Thank you for your responses. Now I need to find another board to replace my MSI NEO 875P. I presently have a 2.4BGig P4 processor but was going to go for the C version at a later date. Now I'm not sure to go with the 865 or get the P4C800 Asus board. I will never buy another MSI motherboard again!

If you guys were going for an 875P board whgich one would you pick?

donfm, you'll want to look into the p4p800 pe (with ich5R),by asus. it is giveing the 875 a run for its money, but dont take my word, read some of the reviews and thats where you'll end up.(asusboards.com)i bought one.

Thanks tommie, that is exactly the board I am getting. The only problem is it doesn't seem to play well with many brands of memroy so watch make sure you look at the ASUS recomended memory list before you buy people.

Actually Intel says there is no such thing as PAT but that the Canterwood has a better memory controller. PAT was made up by marketing types from various Mobo mfgrs to make the 875p look better than it really is. In actuality the 865PE is just using a lesser tweaked controller.

Who at Intel told you this ? If you are basing your statement on the Register news story say so. Personally I don't think it's a very good source.

Okay obviously I've been out of the motherboard scene, but can SIS655 still compare with intel's 865PE chip? I'm just wondering if the spending the extra $30 for the entry-level 865 boards are worth it.

I agree. The only place this news came from was second hand news. Not very reliable if you ask me.

Well, aeverywhere I look Intel is beating around the bush and not answering the questions directly. ASUS has now pulled mention of PAT being enabled on the 865 with their boards and now calls it something else. Point is...everyone is avoiding mentioning PAT except those at hardware message boards and websites.

This is enough for me to say PAT is marketing hype.

well, as far as memory bandwidth is concerned the SIS655 with dual PC2700 DDR gets a sandra score of 3412/3411

The i865PE gets 4503/4484 with dual PC3200 DDR which is it's default setting and it overclocks well.

Plus you get support for 800Mhz FSB P4c CPUs.

Yeah, and I am not sure if the SIS 655 board will support 200 FSB. Guess you could try it out for us and let us know, optimistic. If you are using anything other than a "C" chip, I would only get a Springdale or Canterwood for the features.
