That's real nice stuff, enough to make me want to get one. Only thing I don't get is why you're using the 12x multi? Why not 11x260-270?
Dothan = Big Boy on the block. FX-57 will be no great improvement over 55, so 2005 may be year of Dothan (Sonoma)

See this post for some 3D03 power (aircooled video) :)Quote:

Was just makeing sure I dont crash or limit video OC because of FSB (and AGP). I'll push it harder later. ;)Quote:

Doing 3D (w/ fast video card) at 260-270 1:1 2-2-2-5 w/ i865/i875 and max chipset settings ain't exactly an easy task thou. And even if the board and ram could do over 250 w/ max settings then there is this silly ASUS feature => wont lock AGP/PCI when booted at 200FSB w/ ATI card - so at ~250FSB the X800 is pretty much at the limits as far as AGP speed goes.
But once I apply some better cooling for the CPU the AGP thingy ain't a problem as I need to change to higher FSBs and drop ram to 5/4 divider.
Did you manage to get your other cascade fixed ? Or are we taling Ln2 on cpu and cascade on Ati ? I guess the ideal would be 300x12 at 5:4 240MHz RAM 2-5-2-2. Easy for me to quickly write that though :)Quote:

This is certainly an interesting chip. It looks from your akiba.fi website that the none Deluxe P4C800 can also use the 21 BIOS and work, so I am back looking for a cheap 730 for gaming. I just hope it does not screw up, I promised my wife if I could have an FX-55 benching rig I would not need to mess with the house machine we use for general stuff. She gets mighty mad when my experiments going wrong causes downtime and stops her getting to hotmail ;)
These Dothans certainly add an interesting extra dimension. Opp managed to get nvidia back to the top of the orb again for 2001, maybe macci can get Intel up there again as well .... who would have thought it ?

[QUOTE=macci]Does it give the higher ram speed also at 134MHz (PCI should be locked at that boot-FSB)?
I have the resistor mod for Vcore adjustment so haven't tried other VID mods. VID4 mod + Vcore mod gives atleast 1.7V - which seems to be more than enough. Optimal voltage for this chip for air/water cooling appears to be at around 1.62V.

you only get 3:4 divider at 133 fsb possible at 166 to.
i am using p4p800-e bios 1007e.003 in the p4p800 and the agp/pci lock works ok.
still have a limit of 170fsb but i have not upped the vcore over 1.568v yet.
the p4p800-e allows me to change vcore in the bios but only upto 1.6v but it shows as 1.58v after my p4p800 droops under load.

waiting we might get a new wr :)

TAM's screenshots seem to have the PCI and AGP in spec. Which FSB/PCI ratio is it using? 1/7 or 1/6? And how does dropping to the 5/4 ram divider with a higher FSB fix things?Quote:

Thanks a lot, these are really incredible results, then again I wouldn't expect any less of you. ;)
Andy, yup around 300 zone w/ 5:4 is what I'm aiming for. I also got my good P4C800-E mobo back from The Stilt. Its been thru SPi1M at 316FSB 5:4 2-2-2-5. So with some good luck we might be seeing a Dothan 3D-run at lets say 310x11 5:4 :)
I'll be testing how the 5:4 divider and high FSB performs w/ aircooling first and if things are going as they should I will probably mount my working GPU cascade for the Dothan chip.
And yes ASUS has posted BIOS files w/ adapter support for every P4C800 board. So just make sure you have the latest BIOS flashed before you put the Dothan and the adapter in and there should be no hotmail-downtime :D
The P4C800 does lock AGP/PCI if nVidia AGP card or any PCI video card is used. And TAM was probably useing some PCI card as he was doing only SuperPi runs.Quote:

For some very wierd reason the P4C800 wont lock w/ ATI R9x00 or X8x0 when booted up at 200FSB (for optimal performance). It locks it w/ ATI too if booted up at 201 or any other higher FSB. Dropping to 5/4 means that I dont need to post at 200FSB anymore which means that I get working AGP/PCI locks which means that I can hit high FSBs :)
An overclocked Dothan on a P4C800-E should beat a 640 @ 4.2ghz ?
Is the multi locked ? I should buy a 730 this evening.
Could it reach high fsb ? (currently @ 262fsb on my P5P800)

why you can't post in 1:1 over 200 :confused:Quote:

sure I can but it wont be any good then ;) fastest chipset timings are enabled only when booted at 200FSB.Quote:

wish these adapters worked on Abit IC7 mobos too..the AGP/PCI problem wouldn't be there then and its just as fast in terms of 3D speed - plus it MIGHT give even higher video card OC (this was the case w/ 9800XT atleast) ;)
a quick aircooled FSB test with this current old P4C800+Dothan => passes SuperPi 1M at 9x310FSB 5:4 2-2-2-5
The P4C800-E Deluxe is going in next :D
Can you please post any idea's of the mounting your doing for the cascade.
well true for PAT :(
i hate asus PAT, abit one is really nice instead...
then for benching with ati and PAT enabled you need 5:4 right?
PAT can be enabled (w/ 865twk software) and is actually enabled at 201FSB boot too. But there are other chipset timings that are making quite a difference too (FSB Strap mode, DRAM Latency values etc).
well, i am using AS8 now, and i find pat an improvement in performance, but only for low clocks, with extreme cooling i prefere more mhz than PAT enabled...
FSB Strap mode ec ecc are involved with fixes or other???

Could you post a shot of your score against steve's?
http://service.futuremark.com/compare?2k1=8523922
I believe he has the highest air-cooled score on the ORB, would be good to see them side-by-side.
Kinc has the aircooled WR, see post #127 (there is a comparo too) :)
So far, got my 730 running at 2.52Ghz (210 x 12) with stock cooler and Vcore 1.47 (does 2.4 @ 1.37) and p4p800se. Got Vcore and agp/pci locks in bios with 1009 bios.
@ Macci,
What you posted about the ATI cards might explain why when I booted at 200fsb and then used EIST / clockgen to raise bus to 238+, my computer would lock up within seconds. I was using a 9600XT at that time....maybe I'll switch to a Nvidia card tomorrow.
In a huge hurry but just enough time to post these. Will be back later :)

Just a quick 3Dmark lobby run between SuperPi runs.
@ 3248MHz, card 520/530, Lobby low WR :D

done w/ GPU cascade, poor insulation, temp -81C :D
