Performance Acceleration Technology (P.A.T)
Hi,
just trying to get some *confirmation* about this tech. I understand that it is meant to be a bonus feature of the Canterwood chipset that somehow makes the memory work faster. What I wont to know now is whether this feature only works when you run your FSB and memory bus *synchronously* as in 1:1. I seem to be reading stuff that says it is not available when you run say in 5:4 ratio? If this is the case then its a great *leveller* between Springdale and Canterwood chipsets, where someone wants to run 5:4 ratios. . .Is this true, or am I misinformed? I am reading about G.A.T now, an ABIT feature similar to PAT for Springdale chipsets. . V I P E R L A I R .com Game Accelerator Technology http://tinyurl.com/3eex5 Looks cool, and seems to be getting great results in web reviews (lol Streetracer, F1, sound funny) -- Wayne ][ new specs coming soon! |

Maybe not a complete answer to your question, however it is my impression that PAT will not work if overclocking is enabled. Whether this is due to the asynchonous ratios people usually get between CPU and RAM when they overclock, I don't know. There have been some posts about being able to enable PAT with overclocking on an Asus board, but then only by jumping through a bunch of hoops that includes several bios flashings. Even with jumping through these hoops, it is my understanding that you can only get 10, maybe 15% overclocks with PAT enabled. I don't know if going through these machinations makes the system unstable or produces memory errors. I haven't done it; BIOS flashings in my experience have brought much pain. My sense from my own benchmarking is that PAT gave my system (P4 2.6c, 1gig of PC3200 DDR RAM as 2 x 512MB sticks) no more than 5 or 7 % increase in "results." I got better results from the mild 10% OC'ing I'm doing on both the CPU and the RAM (FSB=220/880, CPU:RAM ratio of 1:1). Good luck. ken |

It's not a simple topic. I can tell you that PAT is enabled on my IC7 at
either 1:1 or 5:4. I can still tweak memory settings and overclock to the limits of my ram with PAT enabled. When I went from two to four sticks of ram, PAT was disabled at 5:4 but worked at 1:1 or when the NB strap was set from 800 to 667 -- which limited fsb overclocking and lowered performance. The Abit released a new bios update that got all the performance back -- even improved it at 5:4 -- though PAT still reads disabled. The 5850+ Sandra memory scores I'm getting at 5:4 now are right up there with the PC4000 1:1 scores I see with PAT enabled. That leads me to believe it's actually working, but just not registering in the apps that normally pick up on it -- like CPU-Z or Sandra. And if you think that's confusing, try to figure out what GAT does, or how to get it working at anything other than the default AUTO settings. According to an FAQ at Mushkin, setting GAT at anything other than AUTO overrides both the SPD and manual timings and runs the memory at 1:1 at settings that equate to 2,2,2,5 in F1 -- faster than most memory will run comfortably. I've never had any luck at all with it, any setting I select either makes the system less stable or shows no measureable improvement. The hassles with getting GAT configured are one of the main reasons I plunked down an extra $20 for a Canterwood board. After reading some of the laments from those trying to emulate the results from the review sites on Springdale boards using GAT, I'm glad I did. In general, the Canterwoods clock higher and don't have to resort to tricks to get good memory performance. Why settle for a simulation when the real deal doesn't cost much more?

PAT is enabled on my IC7-G according to CPU-Z. I run at 5:4 with the memory
at 2, 5, 2, 2 in manual settings. I have not had any luck with GAT. I just leave it set at Auto on both an IC7-G and an IS7-G. -- Thomas Geery Network+ certified ftp://geerynet.d2g.com ftp://68.98.180.8 Abit Mirror ----- Cable modem IP This IP is dynamic so it *could* change!... over 120,000 FTP users served! ^^^^^^^ "Skid" wrote in message news:vdbTb.156614$sv6.860918@attbi_s52...

I've an Asus P4P800 with Hyperpath (the name Asus gives to PAT, see in the article hereafter why yhey did) enabled. The fsb is overclocked at 240 MHz. DDR are Corsair Twin 1 GB (2x512 MB) PC3700 at 1:1 and cas settings of 3-4-4-8. Sandra benchmark gives 5457 - 5334. Compared to the normal values of 5007 - 5005 with the 875P chipset, I found my values high enough and stopped further overclocking. If you want detailed information about the PAT story, there is an excellent article on the link below. There is also an extensive memory benchmark with the P4P800 and some personal considerations of the testers. A must read ! http://www.xbitlabs.com/articles/mai...us-p4p800.html |

I will continue reading up. But what you said is pretty much what I have been reading, that is the Canterwood is the daddy, while the Springdale is a *kludge*?. I have a hunch that the newest Spingdales (AI7 etc) have been re-worked in some way because one or two reviews I read have been by former Canterwood owners who after reviewing the AI7 have decided to keep it instead of their original Canterwoods?. As far as ABIT and Canterwood boards go, there is only the IC7. I have read several reviews on this board and am still undecided between it and the AI7. -- Wayne ][ new specs coming soon! |

the only thing I am not sure about with the AI7, is that it has uGuru on it
and it does not appear to have a way to be disabled. this in turn forces you to use only uGuru for temperature monitoring and such as it has a lock on the sensor ports. -- Thomas Geery Network+ certified ftp://geerynet.d2g.com ftp://68.98.180.8 Abit Mirror ----- Cable modem IP This IP is dynamic so it *could* change!... over 120,000 FTP users served! ^^^^^^^ "Wayne Youngman" wrote in message ...

Hi TomG, I read the same thing. . . snip AI7 BIOS 14 - Released Date: 2003-11-18 3) Disable Winbond W83627HF sensor unit to prevent incorrect CPU voltage information shown in some third party software. http://tinyurl.com/3yhon snip I am a big fan of Motherboard-Monitor, used it for years (you can *tweak* it great) love the periodic HTML-based log. But I figure that ABIT have put some effort into the *hardware-monitoring* uGuru chip, so I am naturally curious what this new chip can do. I like the concept of having the motherboard turning up the rpm's of fans according to temps (I think ASUS has had this feature for a while, Q-Fan?). It seems all the new ABIT boards will carry this feature? It's funny I remember when you bought your IC7-G and the P4 2.4Ghz, that's why I asked if you upgraded! Now IIRC that would have been about 6-7 months ago? I remember reading up on the board at the time, looked v nice but in the U.K it was about £150.00 and the CPU's were about £200. Am I right in thinking that the Springdale & Canterwoods are only about 6-7 months old? -- Wayne ][ new specs coming soon! |

Woger MKII wrote PAT gets disabled if the FSB clock is over 210mhz, and that is a Intel Standard.. You need CPUID to check for this.. Hi, are you sure about that? I never heard anything like that, what I heard was PAT is disabled in anything other than 1:1 ratio. Lol the Plot thickens :P -- Wayne ][ new specs coming soon! |
