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

DSsential1, first read this thread http://www.sagerforums.net/showthread.php?t=9729

Secondly, to answer your question about WPCREDIT, I dont think that would be enough to do it. Correct me if I'm wrong, but I think it works like the bus speed selection (FSB). The setting is set one-time-for-all when the system starts, by reading the state of some pins of the northbridge. In the FSB case its the BSEL pins on the CPU that tells the PLL which frequency to use. This is why you on some motherboards can change FSB by isolate pins by masking them with tape. When the system has booted there is no way to change the setting programmatically. Asus simply found out how intel designed the chipset and included appropiate logic into the mobo.

However, if I had a 865 chipset myself (I have 845 in my 5660) I would have investigated more into this. Of course it would be nice to gain this improvement.

I have the 5680 Sager with PAT fully on!

there are two programms you need to turn on PAT.the first is WPCREDIT the second is PCITree.
At www.x86-secrets.com you see the instruction.
Set with WPCREDIT dev0:Bus0:Func:0 the register F4/Bit1 to 1.
then the hidden dev6:bus0:func:0 will be avable in WPCREDIT!
Then set in dev6:bus0:func0 the register 04 and 05/Bit1 to 1.
so the hidden MMR region in the high memory aera is accessable.
Then take PCITree and go to the dev6:bus0:func0 and look at register 10,11,12,13,14 there is the base address FECF0000 of the high memory area and edit the MMR like www.x86-secrets.com show and you have enable PAT.
Then turn off access of dev6 and MMR and write in a 0 where you befor have enter a 1 Bit.
Sorry i an Austrian(German) programmer,bad english,hehe....

i have with sisoft sandra with CAS2 and PAT on 5200/5210 MB sec in Mem.Performance.

Ah, I was wrong for once

Hmm... too bad the x86-secrets site is in French. I wouldn't mind trying this.

Whoa.. you did this on a 5680??

If I had a 5680 I would have made a program to do it, maybe somebody else can do it for you 5680 owners

Someone get this man a 5680!

need pcr file

been looking all morning for dang PCR file, can anyone mail it to randy82103@atypicalview.net because that would be really great.

randy82103

randy82103, You dont need a PCR file, the only thing a PCR file does is to give name to addresses, but since the french paper only talks about addresses anyway, no problem there.

Thanks!

I anxiously await more developments with enabling PAT on the 5680!!!

I have some more information for you regarding PAT. I have been helping DSsential1 via msn messenger so here is how it works, at least what I think at this moment
Everything on our mobos are exactly like intel wanted and intended it to be. This means that you cant tweak much by software. The FSB speed for instance, like in my example in a previous post, are selected by the pins of the cpu, and there is no other way to change it. This is easy to understand, because neither intel nor clevo wants us to tweak and possibly damage or overheat our computers. Also, its a price stategy of course, with different components aiming at different price ranges. However, asus and msi and the other mobo manufacturer have a selling point in that their mobos are highly configurable and tweakable. Thay make lots of effort to give the customers what they want, and that is an overclockers card. Just compare our bios to a asus desktop bios These mobo manufacturers sidestep intels intentions quite easy by integrate logic on the mobos like for example not let the cpu select the fsb speed, they also use pll's which give you the possibility to increase fsb by small increments. I have investigated into this subject and I was correct before. Asus did enable PAT by fooling the northbridge that it was running with FSB 533 when it in fact was running with FSB 800. So what asus did wasnt anything extraordinary. the 865PE chipset have PAT enabled when running with FSB 533.

We didnt succeed to enable PAT on the 5680. However we changed the memtimings from stock 2.5-4-4-8 to 2-3-3-6 this gave a minor improvement. Also, when we tried to enable PAT, we didnt succeed, but we did _something_, because we gained a minor improvent again. So all together the throughput changed from about 4200 Mb/s to 4400 Mb/s. Not much, but at least something.

We havent got any more info from warp8, but I think he didnt have a 5680, he probably have a desktop.

PAT on 5680

HiHo all !

Sorry is was away this weekend form home,so i cannot reply !
But now i am back ! OK, first i have a 5680, from www.bullman.de ,and i have enable the PAT with this two programms, when you need a screenshot from my CPU-Z or wciat prgramm with fully enabled PAT Technology i can post it, or when you need a screenshot from my register and MMR settings i also can do this.
You didnt need to tweak the Northbridge to 533 BootStrap, it also run with the 800BootStrap, only Asus and some other Manu. get the easy way to tweak this way,because PAT is on in the 533BootStrap, but you can also enable it in the 800BootStrap but you must Tweak some more,then i the easy way of 533BootStrap.
Sorry for bad english again !
I also think there is a way to get the FSB higher then 200FSB,with a hardware mod !I look when i have some time in the Datasheet of the ICS pll and search the pin´s to override the Chip select.

Interesting, I am proven wrong again. warp8, you must have made some more changes than those in the french paper you linked to. Bits 0 and 1 of address 40 in dev 6 was read only for DSsential1, how did you do it?

Also, regarding the pll chip, I dont know about the 5680 but my 5660 have a ICS950201, datasheet is here http://www.icst.com/products/pdf/ics950201.pdf
The only settings are 66,100,133, 200. My setting is 133 (x4 QDR = 533). I know the only way to change it is by soldering pins and I have thought of it but my 3.06 would be heading for 4.6GHz on 200 fsb Tell us more about the mod you were thinking of!

Juhuhuhu !!!!!

I can overclock the BOOK !!!! JUHUHU !!!!
The pll inside the 5680 (Clevo D500P) is the ICS 952618BF !!
I found a Programm for a near same pll on www.cpuid.com/cpuz.htm !!!
I can overclock my 2.8Ghz to 3.2Ghz COOOLLLL !!!!
Pat instructions follow !
I have some Problems with my Win2003Server so i have not much time,sorry!
I am working on it !

Please please please!! More info!!!!
