The '''Intel Performance Acceleration Technology''' ('''PAT''') is technology built onto Intel i875 Canterwood [[mainboard]]s and other Pentium 4 based [[motherboard]]s that based on the Intel D875PBZ reference board. Performance Acceleration Technology delivers additional system-level performance by optimizing memory access between [[Central processing unit|CPU]] and system memory, allowing increased performance to be exhibited at standard operating specification.

There are three types of Performance Mode: Disabled, Partially enabled, and fully Enabled.<ref>[http://www.devhardware.com/forums/memory-35/performance-mode-114624.html www.devhardware.com/forums/memory-35/performance-mode-114624.html]</ref> There may be [[BIOS]] settings that affect this parameter. The PAT status is reported by some versions of [[Memtest86]] and [[CPU-Z]], and at boot time by Dell motherboards.

[[Asus]] managed to turn this same feature on, on their 865PE chipset based boards but called it "Memory Acceleration Mode" (MAM) to avoid infringement issues.<ref>{{cite web |last=Wasson |first=Scott |date=8 May 2003 |title=Asus first to claim PAT enabled on 865PE board |website=[[The Tech Report]] |url=http://techreport.com/news/5193/asus-first-to-claim-pat-enabled-on-865pe-board}}</ref>
