Man this is making me drool over this mobo as it has so many mods and stuff to play with.
Omce school gets out i'll start staring at the bios and see if I can find something cool:)

sorry guys, forgot to post the link :D
heres the p4gd1 tweaker beta i tested for franck
http://www.cpuid.com/download/Tw915.zip
note:
cas doesnt seem to work and 15.6µs gave me a nice boost on my bh5
enjoy :toast:
thx a lot again franck!
outstanding job! :clap: :toast: :woot:
nice :D
hopefully a final version is released soon..don't wanna kill my utts
lol, this tool doesnt kill memory :D
Quick question for those in the know: what kind of HDD is better, SATA or IDE? Or does it not matter?

great Post
The ICH6 SATA controller stops detecting drives over 120MHz PCI-E frequency on my P4GD1 using WD Raptor 74GB. If you keep you PCI-E frequency low SATA works like a charm. :)Quote:

and if you disable it you only have one ide slot wich means 2 hdds or 1hdd and an optical drive.
i would go sata but i dont know how much it might limit the board...
or you get a ide or sata pci raid card... pciE and pci are clocked independantly on this board, right?
btw, just found out something very interesting:
my banias 1.4ghz hit a solid wall at 150fsb. i tried setting the default fsb to 133 through the ct479, no difference, tried all different settings in bios, nothing... 150 is stable, 150.5 freezes the system. i havent tried booting with over 150fsb since i can only boot with 14x and this chip maxes out at 2100mhz...
anyways, i increased the pciE frequency to 110 and now im stable up to 164fsb...
now thats interesting isnt it?
i thougt my banias would be limiting the fsb, but why would the cpus interface suddenly work at higher speeds because the chips vga intzerface is working at higher speeds?
any ideas why a higher pciE frequency actually helps to get a higher fsb?
did anybody check if altering pciE maybe automatically increases the pciE interface voltage? increasing vagp on older intel chipsets helped to get a higher fsb.
i assume that the agp or pciE interface is the weakest link in the chipset and its the first part that craps out when oced, so increasing vagp helped to get a higher fsb, and maybe increasing the pciE freequency automatically increases the pciE interface voltage?
whats the default pciE voltage?
does anybody know where to meassure it?
OR, this doesnt have to do with the pciE voltage at all and its a clock generator/divider issue... hmmm
EDIT: hmmm scratch that voltage thing, i thougt of that since increasing pciE even more doesnt allow me to reach a higher fsb, butfor you guys with dothans thats the case afaik.
and 150 was stable and 150.5 wasnt, wich sounds very much like a clock generator/divider issue...
164/165 is the next step where i get a system freeze all the sudden... thats a 15mhz step, arent some plls using a reference clock of 14.3mhz?
150fsb is the first wall, 10x15mhz, the next wall is at 165fsb, 11x15mhz... coincidence?
Hmmmm, that is very interesting saaya.....thanks for the info all!
I doubt it's the voltage but IDK what else it really could be (how's that for a logical statement :D).
yeah, i just edited my post :D
i think its a clock generator/divider issue...
I'm think this is because of the overclocking lock Intel tried to implent on this chipset, where max overclock is 10%.Quote:

kamerat, but i can reach 150fsb easily, and my default fsb is 100...
so that would be a 50% limit.
if its a overclocking limit thing then dothans should have problems pretty much exactly at/above 200mhz fsb as thats a 50% oc for them from 133mhz fsb. is this the case?
vapor, i tried 120 pciE, nothing...
so pciE and pci speed are coupled meaning a higher pciE speed results in a higher pci speed?
saaya - 165FSB must be the wall for your Bannias.Have you tested it in 865/875 chipsets ? BEcouse only there you will be 100% sure.
Also,for 120-135 PCI-E freq,first adjust chipset Voltage(1.6-2.0) then apply desired PCI-E freq. I needed 1.97v for 131 PCI-E and 285 MHz 2-2-2 1:1.
some other things related to P4GD1/P4GPL-X
-first one has a better chipset.Same settings for 285 2-2-2 in GD1 cant work well in GPL-X.Max attainable in GPL-X was 271 2-2-2.
-for high multi Dothans (750-780) use boot FSB 167+. If u boot at lower 100-166 FSB you will get lockups in windows when trying to raise FSB with Clockgen.
-both boards works well even with New CH-5/BH-5 modules,thing that was almost impossible in previous I865/875 chipsets.I personally ran 4x512 New BH-5 (2x512 twinmos pc3200 1A4T + 2x512 twinmos SP pc3500) @ 235MHz 2-2-2, Prime95 stable.
I never tested 200 MHz boot in P4GD1 since im on a high multi dothan.Could someone make a compare with a boot (lets say 175MHz) and upping with CG in windows to 200 -Vs- boot 200/windows 200. Im very interested for Pi 1MB adn CTIAW results made in this 2 ways.Thanks.
first boot on my p4gd1 + ct 479 + pm 740 1.73 533
black screen , no display :/
what can be the problem ?
with a matrox millenium pci , the same black screen , i hear the HDD but no display
flashed a dothan compatible bios yet?
how to flash without display ? :o
Likely, the BIOS you are using is not compatible with the Dothan. There are a couple of ways to update it. One is to use a compatible CPU (P4) in the board and update to the lastest (Dothan compatible) BIOS. Another is to "hotflash" you BIOS EEPROM chip in another board and place it back into your motherboard after it has been flashed.Quote:

many guys said it can be a problem
i ve a p4 here , but there are 2 pin broken :/
I'd sugges that you guys use a known good OCing s478 (i.e. 2.4c) to check whether PCIe value would impact your stability or not. As with my posting here, http://www.xtremesystems.org/forums/...ad.php?t=76691, there was no tweak on PCIe to hit past 250FSB. My Dothan was also able to hit 2.7Ghz without PCIe tweak (though, it's just 225FSB http://valid.x86-secret.com/show_oc.php?id=32305). I don't have a shot/validation link of higher FSB/low multi for my Dothan though, I forgot to take a shot before selling it :)....
I guess I'm gonna go buy a new pair for myself then :)...and just join the fun again :)...
no i dont have a 865/875 board, i might get a p4c 800 e deluxe though.Quote:

is the cpu fsb limit always a rock solid wall that comes out of nowehre or is there a discrepancy between max full load stable and max idle/windos stable?
hmmm i think i will compare 140fsb with 100 pciE and 140fsb with 110pciE to see if there is a difference...
too bad there is no multi option in p4gd1 so we cant boot at low multi/high fsb...
skirms_fr, your using a pentium 4 cpu?
to me it sounds like your problem is that the default setting in bios for this board is that pciE graphics are set as default display device.
im not sure if this works, but you could try to enter bios blind and go directly to the pci/pciE option in bios and change it.
this only works if your system initializes properly, wich i dont know...
or your cpu is simply dead since 2 pins are missing... can you test the cpu in another system or have another cpu to try?
i have a celeron D 2.4ghz i used to flash the bios on this board, i could use it to see if the limit is a mainboard or a cpu thing... but from initial tests it seems to be an incredibly bad ocer... :DQuote:

after all the pentium m and pentium4 use a different signaling voltage for the quad pumped fsb interface iirc, so the adapter is in between the board and cpu and might cause those fsb problems too...
EDIT: did anybody with a dothan on a p4gd1 ever find a similar problem to what im having? a wall at 150fsb and then 165fsb?
saaya....most Banias's can't hit 170FSB from what I know (honestly, I don't know a whole lot), so you're in about the right place right now.
Could be something else limiting you for sure, but I wouldn't worry about it.
If you've got my 780ES there, you can test with that if you like.

Another thing: set CT-479 jumpers to 100,not 133.It helps reaching a higher FSB.
Im still looking for a 200 vs non 200 boot to see if the P4GD1 reserve us a surprise,even a little one :)
And thanks for the PM :toast:
