Intel PAT Compared On 865PE Boards
Xaley writes "There is roundup at VR-Zone on
several 865PE boards
which came equipped with Intel PAT feature and definitely consumers will be
happy to purchase these boards without paying a premium price that Intel has
charged for their 875P chipset. A typical 865PE board costs around $150 and a
875P board costs around $200-250 so it is a cost savings of $100. Of course,
Intel won't be too happy about it since sales of their 875P chipsets will be
affected but there is no stopping for motherboard manufacturers from adding in
the PAT feature into their 865PE boards now."
A lot of people say, "What's that?"
It's PAT.
Intel should stop reusing acronyms. PAT = Page Attribute Table, a feature in PIII+ processors that helps manage caching of memory ranges.
A deep unwavering belief is a sure sign you're missing something...
Funniest quote from the whole article:
There are so many good marketing specs thrown into 875P that make the hardware enthusiasts to go after it and even prepare to pay a premium for it.
I take back all those nasty comments about hole-in-the-wall-2-guys-in-a-dorm-room-'review' sites. Well, okay, not all of them- even this guy has some SERIOUS grammar problems :-)
Please help metamoderate.
since AMD doesn't harrass/sue third-party chipset suppliers (like VIA) so no one can get away with playing games like Intel is doing with PAT. I prefer nVidia nForce2 chipset boards these days. YMMV.
...what'll stop the overclockers/enthusiasts from turning on PAT? Won't that still eat into their sales of 875P based boards? Somehow, the fear of voiding our warranty never enters the equation...so what's the deterrent?
Q: "Why do sound techs say 'check 1, 2'?"
A: "Cause if they could count any higher they'd be lighting techs."
I read it as Port Address Translation. Expansion of acronyms would be helpful in the original post. -Chuck
The 875P Canterwood chipset with PAT supposedly provides a 5-7% performance improvement over 865 chipset.
WOO HOO!
TMFA's! When will we start patenting acronyms?
PAT=
Port Address Translation
Page Attribute Table
and now Performance Acceleration Technology
Good security is based upon reality and common sense. Common sense is a function of having common knowledge.
200-250 is not correct in many cases for the P boards, I just got a MSI 875P Neo board for around 150 and it has all the goodies like SATA and got excellent test results.
"There is a constant pressure from Intel to advise motherboard manufacturers not to offer PAT into their 865PE boards but on the other hand, there is a considerable amount of pressure from consumers demanding PAT in their 865PE boards. There is a great dilemma faced by the motherboard manufacturers here whether to include the PAT feature or not. However to keep the sales going, it is advisable add in PAT into their 865PE boards to keep the consumers happy."

All of this worry over $100 bucks difference? That amounts to about 1 days work for most of us. We are more lazy than I ever suspected! Arguably, this is what leads to early psychosis.
+2 cents.
Word out of Intel is that there is a future revision of the 865 chipset will have PAT disabled in hardware before being shipped to motherboard manufacturers. The system will just lock up if they try to enable it.
So keep in mind this situation is temporary.
It may be less than a day's work difference in price, but that doesn't mean it's insignificant. Imagine if someone offered to sell you a candybar for $100. Which would you say: "Gee, that's less than a day's pay." or "You've got to be kidding."
If you're paying $150 for a motherboard without PAT and $250 for one with PAT, that's a 66% markup for 7% performance increase. Not all that impressive of a deal.
This feature is useless for business applications where reliability is essential. While the PAT logic is in the 865 chipset, Intel does not guarantee that it has passed chip-level testing. It may work, it may not work, it may only work over a limited temperature range. It falls into the same category as overclocking the CPU. You don't know if the chip passed the test for a higher classification and was marked for a lower speed to satisfy market demand, or if it failed the test for reliable operation at the higher classification. If you want that guarantee, you pay the premium for the 875P.

Most of the 865 chips are basically rejected 875 chips. Intel didn't want to waste the chips so they came up with the idea of just renaming them 865 and sell them as lower performing chips.
Your right in that intel should have done something to permanently disable the chips.
