P4GPL-X + Dothan OC problems

[albertwesker]

Please give more details!!!! You're the only one we "know" running this configuration, give us all the details and tweaks!!
I bet you're on an IDE HDD right??

C

I don't use any tweaks, if you want to reach an high fsb, you only have to set the PCIe frequency higher than 120 MHz.

For example:

PCIe = 123 --> 2,2*123 = 270
so you can get a fsb of 270 MHz, if you use a pcie clock of 123 MHz.

The PCIe clock does only overloads the HDD ( if you use an IDE HDD on the Onboard Controller) and the Northbridge. If you consider the formula ( 2,2*PCIe = FSB), there is no problem with your graphic card. You can also select an higher PCIe clock, but it have to be higher than FSB/2,2.
With a Vchip at 1,6V you can reach a PCIe clock about 220 to 230 MHz. For Higher PCIe clocks, you have to do a Vchip mod to 1,9V.

I use a Promise PCI SATA RAID Controller with 4x WD 250 GB and Vchip at 1,6V, so i can reach a FSB of 290 with no problems.


here is my result in 3dmark 2001:



P-M @ 3150 MHz + 7800 GTX @ stock

the 7800 GTX isn't the best performer at 3dmark 2001, a x850 XT PE should reach 40-42k easily.

OUTSTANDING!!!!



have you tried a P4GD1 also?? Great results... will a standard IDE HDD work without the additional PCI card??

i haven't tried a P4GD1, because i couldn't buy this board in germany. The P4GD1 has got the same layout as the P4GPL-X, but it has got 4 ram slots, so you can select the same settings, which i posted.

If you want to reach a high PCIe clock, you have to use a PCI Controller for your HDD's, otherwise the HDD's wouldn't give a signal, if the PCIe clock is higher than 110-113 MHz.

Only problem is that there is none SLI PM mobos there so dream on But great idea non the less

really think so? then take *this*

that may be an option some time soon.. who knows. then we may be running
a cpu on a board that it wasn't ever designed to run on - thanks to an
adaptor (ct-479) - and then we might even be able to run 2 pci-e cards in sli-
mode on that same board - again not designed to run like that - using yet
another adaptor....
now that would be something. hail the adaptor-manufacturers... given the
muscle the dothans have already shown, we might see some very very good
stuff (scores) based on this - some day...soon...



@ albertwesker, you don't happen to be dukee from hwl?

[marvt74]

Thats possible the greatest sight i've ever seen

[albertwesker]

yes, i am dukee from hwlxx

wtf? thats crazy ....adapter-o-rama.

[HITAC]

try using this formula to calculate the necessary pcie frequency:

pcie x 2.2 = fsb

so if you want an fsb of ~225 mhz you should try somewhere around 102 mhz pcie
- maybe try 100-104 mhz, whatever works (best)

Doesn't work....

All over FSB215 (215,5 real) is NOT stable.
ram async, more voltage..... all tried....


Should I get another PCI/PCIe clock with setting PCI to (e.g.) 104 or higher?

FSB215,5 PCIe100 -> PCIe 107,73 (clockgen)
FSB215,5 PCIe105 -> PCIe 107,73
FSB215,5 PCIe95 -> PCIe 107,73



OK.... I will try it now with IDE-HDD, PCI-raid-HDD and Jumper@400 instead of 533.

[HITAC]

What FSB is set in the CT 479? I get better fsb with jumpers in fsb400 than fsb533.

BINGO !!!
I love you.

More FSB is now possible...

OUTSTANDING!!!!

I have used onboard ICH6 PATA on the P4GD1 up to 138MHz PCI-E and 295MHz FSB. Used a Western Digital WD1200JB (120 GB).

There is also an PCI PATA RAID controller integrated on the P4GD1.

Look at key features.

Well seems Dothan on pci-e is looking better and better, my 730 is arriving on the 8th and adapter and board on the 11th, so I have three days for flashing bios 1006.001 XD

To get high FSB speeds FSB400 jumper is the way to go then?

PD:Wondering if a 750 would have been better due to higher multi. The 730 has 12 multi but which has 750? 13,5?

the 760 has 15x default, so i guess a 750 has 14x (14x133=1866, about right)
iirc intel doesn't offer .5x multipliers

[Jericho]

m730 = 12
m740 = 13
m750 = 14
m760 = 15
m770 = 16
No 0.5x options



how could i get them multipliers wrong !

i took the FSB533 MHz jumper and i can run a FSB of 290 MHz with no problems.

the P-M 750 has got the multi 14

just clarification, so you set it to 100Mhz jumper? Sorry if this sound a repeat question, but I just want to be absolutely sure because mine is arriving real soon.

i set it to 533 MHz (133 MHz)

[HITAC]

I definitely get higher FSB at 100/400 Mhz jumper.

[Jericho]

I definitely get higher FSB at 100/400 Mhz jumper.

Made no difference for me

[death metal]

Hehehe, ok. Thanks guys, so maybe it'll work, and maybe it wont'. I gues I just have to try =)

[Playful_Buffalo]

nice work

[albertwesker]

the P4GPL-X works great with the 7800 GTX

now aquamark with 287 MHz FSB

[16floz470ml]

So with this board you can change the cpu multiplier? The p4gd1 does not allow you to change the multiplier? What is the deal with that? He is running a 750 with a 12 multiplier.

[Neova]

Albert,

What kind of cooling are you using? Lets see some pics of your rig!

And it does appear you can change multi with the P4GPL-X. Wish I could find that MB around here.

[markodude]

@16floz...
EIST from www.cpuid.com lets you change the multi in windows...
