Dothan @ CT-479 - howto and fixes.

[leejsmith]

I tested the cascade before i bought the xp 90 it worked very well but i wanted this on air ready for use in a htpc.

The brackets are a bit fiddly to install but i just about have it sorted now. If only i now some one that could make a new p4 retension bracket it only needs the height increasing to match the added height of a ct-479 just a couple of mm and any p4 cooler will fit no problems.

Naturally, LOL, cause you are already near ambient with the xp-90, lol. I think water is useless on these things, unless it is chilled.

Nice work on the brackets though!

funny you should say that i thought of that a while ago and posted in OC.com forums... didnt have access to XS just reged here... if someone was willing to make them i would be up for two of them.

*edit*
if im right the height increase should equal the height from the adapater? if someone was able to measure that would be great. if no one is able to make some when i do some calling around on my next day off. To see if i can have a few made.

OK, this is really pissin me off. Someone has to have a fix for this multi issue. I can get maybe to 175, but I have to creep up and that doesn't get me anywhere near where I need to me at 12X. I really don't feel like waiting for Asus to get off of their duffs to make a new bios, and I don't feel like buying a new board.

Edit: Do we know that the P4P800-SE can get around this?

cpumsr will change the multi for you once your in windows but as your not setting fsb to 200 in the bios you might have the same problem i have gettings the fsb over 168 was impossible no matter what multi i used.

edit: just noticed from your post yes you have to install the driver for cpumsr to work.

[leejsmith]

I think the p4p800-vm is the only bios that has multi adjuster.
but it has not fsb /vcore options so thats a no go too.

it's still early days the p4p800 and p4p800-e are not officialy supported yet.
why add options to one bios and not the other when the boards are almost identical ? the only thing i can think of is the vm boards are for sff / htpc so they think adding the multi options will allow better power management but on the p4p800 it's not needed.

Asus just needs to get the BIOSes flowing!

What about 200 FSB pin mod(under adapter)? Ok, it doesn't give you room for finetuning with only the multiplier adjustable, but it's far better than only 133 FSB...

Or is there an undocumented 200 FSB jumper combination on the adapter?

What do you think is the reason for the max 170 FSB (statement in the first post)? Is it because of to low Vcore or have someone tried that too (VID mod)?

[leejsmith]

I think the main problem is the 1.6 400fsb dothan i am using a 533fsb would be better but i dont have the money to get one at the moment unless i get another one from ebay.

Also using 200fsb with a multi of 16 would be a high for air cooling so the 533fsb with 12 multi would be the best option.

I have used vcore of 1.6 when it only needs 1.5 to run at 168fsb so i dont hink any higher vcore will help and the lowest multi of 8 still failed at 169fsb.
I could add a 2nd vid mod by putting vid2 to vss for 1.64v but i dont think it will help.

168 fsb is not that bad for a 100fsb chip

[Mats]

Thanks for the info! I meant that you should take advantage of that unique multiplier control. Set it to x12 or x13 and then do the FSB pin mod. But as you say, it probably won't work anyway.

Does the two FSB jumpers represent BSEL(0) and BSEL(1) respectively, or is it more complicated than that?

...and yeah, du do have a nice overclock there!

[Astral7]

Yeah, that's the problem, there is no multi adjust in bios except for VM. I too have the 1.6/400FSB and 3.2GHz is just too high without xtreme cooling.

[Mats]

Sorry, I meant VM only.

[leejsmith]

What is the fsb pin mod for 200fsb ?

The other problem with the vm is a lack of other overclocking options. vddr will only go to 2.6 in the bios and the ddr booster will not work so memory will be a limiting factor.
I could try the vm bios in the p4p800 at least the booster will work and vid pin mod for cpu vcore.

Sorry, I meant VM only.

http://www.xtremesystems.org/forums/...134#post872134
Since the FSB jumper configuration is 2x3 pins, I just thought that you could do it with them. But since it's on the PM side of the adapter I highly doubt it.Anyone tried?
On P4 the two pins together gives signal for either 100, 133 or 200 FSB, dunno what the fourth combination gives... 166?
On PM I only know about 100 and 133. I wonder if the other two combinations will work.

[Astral7]

I'm going to pull a VM out today, so I may have time to give some of this a try. The vDimm issue is an easy fix with grabbers. Maybe just a limitation of the 400FSB chips not wanting to run over 180FSB. I'll see what I can figure out later today.

[Schnubbi]

Thats no problem with the multi. -> eist ghost mode & clockgen ghost mode


You download Eist ,extract them .
In the main menu are a file called save.txt ,open it and write the FID (multi) that you want ,save the file.
Than you make a shortcut to the Eist main program open it and write after for example "c:\eist.exe" -file=save.txt (save.txt is the name in that you change the FID (multi)

Put the eist shortcut now in the autostart directory ,thats all.
The next windows start the multi will be changed automatically in the background.


If you can read a little bit german you can read this. (i have wrote that for our german forums) [picture to the how to]

http://www.forumdeluxx.de/forum/show...&postcount=145

Clockgen:





EIST: (same procedure as clockgen with the .txt in the main directory and -file= in the shortcut)




€dit: With this setting in windows you can run over 200Mhz fsb and 4:5 ram ratio for example 200Mhz fsb 4:5 ramratio = 250Mhz and coldboot problems are past,too.

Important:
If you work with clockgen too (automatically start), rename the eist shortcut in the autostart directory with a letter that comes before the clockgen shortcut. (execution order)
Example: eist shortcut -> shortcut a.exe / clockgen shortcut -> shortcut b.exe

[datura3]

great idea schnubbi. I'll give that a try.

[datura3]

Nice work, look's like a prospective approach to the shim "problem".

Any board reccomendations?

I'm picking up a cheap Celeron tommorow to flash with (Yay! 2 computers for the price of three ) Maybe I'll buy a cheapo 478 board and give the combo to my mum, I'm sure she needs a gig of ram.

Thank you for the welcome uclajd

Is that hole punch shim just paxmate sound damping foam?

This is interesting. But I can change the multi using cpumsr; I just can't go over a certain FSB with my P4P800-DX (using P4P800-E bios). Not sure how this would help that issue.

What board and bios are you using Schnubbi?

[socrilles]

if you go to notebookforum.com in the dell 9300 page, there is a thread called cheap processor upgrade (or something to that affect) there are people there who would be happy to trade a 1.6 ghz 533 fsb, for a 1.6ghz 400 fsb for any1 who is interested

I have the Asus P4P800-Se with a Pentium M 2,0 Ghz C1 .
with automatically eist & clockgen ghost start i have 12x multi and 238Mhz fsb in windows.
One of our Forums has broken 300Mhz fsb with his Asus P4C800-E deluxe , now 315Mhz fsb only when pat is off.

If pat ist on he can only go 270mhz fsb. (sure a bug)


P.S: Sorry for my bad english

[uclajd]

Yeah, the SE's are nice for the Dothan. I think some boards (like the P4P800 and DX) are just FSB limited at about 170-180. I have had this board boot into Windows at 300 before though (using a 2.4c on straight water), so I don't know why this happens with the Dothans.

Think I might have to pick up an SE.

@uclajd

have you try to deactivate pat and set perfomance mode standart ? If not try it (voltage is enough ?! )
Perhaps the bug is on the Asus P4P800 (E) ,too. ( i dont know)

I cant say this exaclty, because in the moment i only use single channel. I wait for my second Twinmos Twister pro.

[uclajd]

Yeah, I could never get PAT or performance mode to work on this crappy board, LOL.

Edit: Just sniped an SE on ebay for $61.

uclajd, do you have a 400FSB Dothan? That's what I have and with the SE I can't get past 165FSB even with 6X multi in Windows. The 533FSB Dothans are the ones everyone is hitting these high FSBs with. If anyone has been able to get over 200FSB with a 400FSB chip please post it.

I think the VM is dead. It was acting funny last time I used it with booster, and now I've tried three diff. cpus, five sticks of ram, two diff. PSUs and VC. No luck. So I'm gonna start working on some cooling for the SE.

Thats right.
The 400Mhz fsb Dothan i personaly know only were able to start max. with 190Mhz fsb.
Have you got a 400Mhz fsb Dothan ?!

[uclajd]

No, I have a 760 (2.0 533).
