Sager 5680 with 865PE chipset enabling PAT (Perf Acceleration Tech) on motherboard? - Page 3

I actually am very interested in enabling PAT, as well as playing with this nifty overclocking utility. When Warp8 posts how to do it, I'll be among the first in line.

I'm a little wierd. I love beating my friends' uber desktops in terms of power and speed. PAT is one more step on that road.

Edited to add: Oh yes, I have a 5680, and am still loving it to pieces.

Not literally.

Thanks all,

- Aeon

Pat

Hello !

I need a Tool to write in the Memory Mapped REgister FEFC0000 !
I have a Tool (PCITREE) but i want a tool that i can start automatic with windows startup, like a commandline or dos tool!
Is there any programmer outside that can make such a little tool,or know where such a tool is for download.
Overclock with CLKGen is over commandline ,thats nice. Dev 0:0:6 accessable is over the WPRCSet in autostart,we only need a tool that write in MMR FEFC0061 a 71hex instead of a 58hex.
Than all start automatic overclock and PAT on.
the next i must change or lock the freq. is the multiplyer of the AGP,PCI Bus to get higher overclock, at 220FSB(38PCI) the Audio Pci hangs and the Rambus multipl. i want also change,all this is no problem with the whitepaper from intels i865p and the access of the MMR Dev6 !

Thanks to all !

That program worked to overclock my 8890 I assume. Normally running seti it takes aprox 2.8-3 hrs a unit, overclocked to 3.1ghz, it does them now at 2.5-2.7 hrs per unit. So it did do something.

warp8, by changing MMR offset 61 from 58h to 71h you change 3 bits in a reserved area according to intels datasheet. You also lower TRAS 2 clocks, but you dont change CAS latency or any other memtiming settings. Neither Intels datasheet nor the french paper says something about these changes. Where have you read about it?

Also, what parts of the whitepaper are you referring to that changes the multiplier? To my knowledge, and according to the whitepaper for the pll chip, you cant change the multiplier.

On the 8890, the Clock Gen program seems to take effect immediately. Furthermore, any changes are automatically discarded on reboot (either shutdown, restart or hibernate). The auto reset is probably a good thing. Of course, if you want to always overclock, you can place a shortcut in Startup.

Re PAT - My French is rusty, so possibly what I found may be wrong. However, I do not think that the paper provides a way for us to activate PAT. It just explains the interplay between the configuration settings, the chipset and the CPU. It also explains how Asus was able to enable PAT on a 800FSB - 865PE board. It also provides the answer as to why so many of the other 865PE notebooks have PAT enabled. As I understand it, the 865PE supports PAT when the FSB is running at 533MHz.

As Henrik discovered, you can use the information to reset your memory config from CAS 3 to either 2.5 or 2, assuming that your memory can support it.

Cas 3? What RAM are you using? My 3200 is CL2.5...

Yes, this is how it is supposed to work. I cant understand why it works like people says it does on the 5680.

Also, to clarify things about the PAT, the french paper and memtimings. Everything about changing memtimings is fully documented in intels datasheet, its no secret at all, and it is not supposed to be. On the other hand, the 865 chipset does not officially supports PAT by intel and therefore nothing is documented about it. The french paper suggested an undocumented way to do it, but this didnt work on the 5680. I havent verified that the way warp8 now finally wrote he did it works, but I'm curious where he did get the information about it.

the ram in my 5680 has horrible timings its cas 3 and like 8-3-3 no wonder it runs at 200mhz

Dear god if you guys manage to write a program that enables PAT, overclocks, and controls fan speeds with the temperature readings, I seriously will crap my pants.

Sounds like we got MUCH more than we bargained for with Sager... I wonder what the Alienware fanboys have to say about this, lol!

Gimme your 5680 and I will write it for you...

I would in a heartbeat if it wasn't my primary work PC! I almost wonder if you could work something out with Adam @ PCTorque with you getting a loaner PC, or a serious discount off a 5680 in exchange for writing performance enhancing utilities that they could brand as PCTorque Utilities? Might be something to think about for both you and PCTorque!!!

Think about it, you'd get a better computer, they could sell more PC's because they could sell them as overclocked with PAT enabled, etc... Easily making a run at Alienware

I doubt PCT will want anything to do with this - being that they wouldn't want to give us any reason to void a warranty I understand!

Henrik - a few benchmarks have trouble on my machine, but it has been running fine at 3.1 with the agp at 74. Im going to leave it at 2.8 though being that I dont like overclocking the agp/pci like that. As far as I know, there is no way to lock it using this MB, right?

To Henrik

Trust me !

I have PAT ON !!! and cas 2-2-2-5 at 200Mhz .
And the multipl. of the Dram and Agp is also changeable.
Pls give me your mail and i send you all my whitepapers and screenshots !
Thanks i must go sleep now. Sorry long day !

Well, the question of the day is if he really have enabled PAT or not. Maybe he got fast memory thoughput because of his memtimings 2-2-2-5. They are the fastest possible.

Odd...on my 5680, ClockGen takes effect immediately. It defaults to the BIOS speeds on restart.

Thats how it should be. I dont know why some had to reboot, I think they have got it wrong somehow.

I have an 8890 - came stock setup with CAS 3. Not sure whether or not the memory can do better. What machine do you have? Did it come with CAS 2.5 or did you have to modify the settings?
