thats weird.using CTIAW to check it says my PAT is fully enabled.and all i did was just enable memory acceleration in the bios

question : with fully enabled PAT its tougher to oc right?or am i wrong?

i know why you got full enabled PAT. Its because you are running <200fsb. my prescott last time also full PAT enabled with just 170fsb+-. too bad i cant make it till 200fsb. now running with 2.8C and oc a bit already exceed 200fsb. Even enable it using tweak865 also only manage to get partial enable.

guys , who wanna try this ... no need to flash bios for fully PAT enabled .... check this out here .... care to share some result if anybody try this ... want to know wether it's working or not ...

@sang_karim
Memset have more settings compare to the Tweaker865, as i previously use both before.


@pengster
If you are mentioning on the 865 chipset, i guess would there be any constraint since we are forcing it to enable the PAT? On 875 board, OC n PAT doesnt limiting each other as i use it before.

hmm.. tonight go home try and see how it works. hopefully it can fully enable the pat.

Here are two screenshots comparing disable and enabling the PAT on my ai7, juz that some of the setting change and nothing significant.

The PAT is fully enable as i juz read some review on the net.
NB Strap 667fsb, GAT = A-A-A-D-D = Fully Enabled PAT
NB Strap 800fsb, GAT = A-A-A-D-D = PAT Disabled
NB Strap 800fsb, GAT = T-A-A-D-D = Fully Enabled PAT
NB Strap 800fsb, GAT = SR-A-A-D-D = Fully Enabled PAT
NB Strap 800fsb, GAT = F1-A-A-D-D = Fully Enabled PAT

Seems that try to set GAT option in bios doesnt allow the comp to boot up, it juz stuck after finish displaying the POST. Weird though.

KahLooN, do you get extra overclocking when you increase your vAGP?

For now, I can't even run 250MHz on 5:4 dividers, although I know my RAMs can take the strain. It must be because of the four RAMs slots used up.

Also, my AI7 gives me memory error beeps when I try to enable GAT.

Also, try reducing the DRAM Idle Timer. I lowered it to 8T and I got a boost of 100 3DMark03 marks.

Well i think the vAGP helps to stable the system, but im not sure till what extend as last time some forumer say is better to max out the vAGP.

Maybe coz you are running with all the ram slot occupied? Have you tried with juz 2 sticks?

Regarding the GAT stuff, im not so happy with it coz supposingly the ram timing 2.5-4-4-8 can enable the Turbo mode. As my previos board and ram can do that, but not on this board. Perhaps maybe need some tweaking i guess.

For the Memset setting, i dont have much time to test all the different settings. Maybe when im free i will try play around with it.

Well, I wouldn't want to waste my time since I have no other choice but to run with four sticks to give me a GB of RAM. Maybe I could try it someday

Does GAT tighten timings on the northbridge or on the RAM itself? And do you have CPC enabled?

@KahLooN
i have the same question like colin, does cpc disabled can perform better??

i tried just now but not working for my p4p800x.

The GAT setting tighten the setting on the ram only as it change several parameters that i have shown in the screenshot.

For the CPC setting, i usually disable it. This is what i set in the GAT setting, A-A-A-D-D.





@kabukiawie
The CPC if im not mistaken related to those setting such as 1T or 2T. For intel board, those timing make no impact as disabling it will help to gain a better frequency. I myself follow what been say by forumer, hope that helps.

Back during my Nforce2 days, enabling CPC helps you to gain extra bandwidth but limits FSB. Disabling it makes the opposite, and is a requirement for double-sided RAMs.

Guys, thanks for the information.

i disable it and see how it works. it seems the newer memset is not that easy to use compare to older version. Older version can just put a shortcut at startup then it load the setting automatically after you start windows. hmm.....

Usually the CPC is recommended to be disable according the overclockers in other forum,the reason behind is to get higher fsb. Another thing is also to play with the GAT/PAT settings.

too bad in p4p800x the pat settings is really limited. hmm...... hows your p4p800x pat setting?? share share...hehe

Yea.. Tried with my p4p800 dlx last night. It wasnt works for my mobo. Guess maybe only certain mobo can use this option.

hmm...i'll try it tonite la ... just up the FSB to 201 and try that trick .. will report it tonite ...

ooo..... even with your p4p800 dlx also the same?? hmm.....

Just tried the method posted by sang_karim, and I'm happy to say that it works for me.

My AI7 cannot boot with 240FSB with full PAT enabled, so I tried the workaround instead. Placed the command switch into the boot.ini, set the FSB at 200 and enabled PAT, went into Windows and used Uguru to bump up the FSB to 240.

Now I'm happily running with full PAT with faster memory. I'll post some pictures later.
