the p4p800 performs just as well as the p4c800e, so y go with p4c800e when it's more expensive than p4p800??
 
honestly the P4P800s are just fine, it's just that some people want the extra features that the P4C-E has to offer, like Intel LAN rather than the Gigabit LAN, which was one of the big dislikes with the P4P800 boards.
 
The P4C800's have more SATA ports, Intel PAT technology and ECC ram support. So theres a few features that the P4C-800's have that P4P800's don't. Its all about preference.

PAT doesn't make a huge difference but it helps some. So I think that P4C800's are faster. Just not enough to justify the $60+ difference in price.
 
Oh, and take note about the difference between a P4C800-E Deluxe and the original P4C800 Deluxe. The original mobo was the first 875 mobo out and it was great, but it used the ICH instead of the ICH-R, which is found on the E, and even the P4P800 deluxe. The Intel LAN is found in the E but the regular P4C and P4P both use Gigabit LAN. There is a downside to the P4C800-E 875 chipset, which is the fact that PAT or the Intel Performance Acceleration is disabled on the mobo when occupying all 4 memory banks. This shouldn't be a bid deal, but it was not a problem for the P4P800 deluxe. I have both boards and the vcore voltages both stray a little, but nothing too consequential. The P4C800-E's voltages seem a bit more stable, but it could be just my specific board.
 
i agree that it's all dependent upon the user's preferences....for me i don't use SATA or RAID so i guess deluxe is too much for me....

so does PAT on the p4c800e forces the ratio to be 1:1?? and is this the same case for p4p800 with MAM on? i'm assuming PAT = MAM from threads around here.....
 
PAT does not force the ratio to be 1:1. You only get the 1:1 ratio provided your memory can handle running at the appropriate frequency opposite of your FSB. Such as 800MHz Cpu's use the DDR400 memory, 533's use DDR333 and 400MHz FSB chips use DDR266.

At least this is the case with the P4C800 and P4C800-E. As well as the P4P800. I forget what other settings you have to use to get the 1:1 ratio. I've been working on cars all day and I am tired of typing now.

let me put it this way.......to have PAT/MAM enabled on the p4c800e/p4p800, the ratio has to be 1:1........and i was wondering if this is the case???

i heard also only the p4c800e can still have PAT enabled even when the ratio is 6:5 or 3:2, since it's i875 that officially support PAT technology rite?
 
I have pat enabled with no issues I have it in turbo and ram performance enabled
The differences which I made my decision were the intel lan which uses csa the extra sata in the future when I upgrade my hd's I also use the ide raid and it comes with sata power cables thats 20.00 right there where the p4p doesn't

I have the P4C800-E Deluxe, and the Intel LAN *is* gigabit (specifically, Intel PRO/1000CT CSA gigabit Ethernet) and uses Intel PROSet drivers. The 800 Deluxe uses 3Com gigabit Ethernet. I'm not knocking 3Com, but the Intel solution used in the E (and the P800 Deluxe) doesn't use the PCI bus, and thus isn't bottlenecked by it.

I have the P4C800 Deluxe which has that 3Com Gigabit Lan. It is a very good nic with alot of features such as built in diagnostic/loopback capabilities and so on.

It does use the PCI bus. In all reality though that's the kind of speed difference that would most likely barely even show up in a benchmark. What is really important in favor of the P4C800-E is the fact that the ICH5R has better RAID performance than the Promise solution onboard the P4C800. The same goes for the P4P800 network interface.

As far as PAT working on i875 boards with a memory ratio of anything other than 1:1, the only comment that I can make is that CPU-Z reports PAT works when using a 5:4 ratio. However we all are aware that 1:1 gives you the best memory performance.

Also, there's a lot of discussion about whether PAT works at 1:1 on 865PE boards with an overclocked 800FSB processor.

there is a way to get PAT/MAM on the P4P800 when you overclock past 200 fsb but you have to use two different bios flashes to enable it. Info
