nice oc macci, what temps did you get under load using the peltier? And what kind of Peltier was it (200W ? more?)
I'm thinking about getting a Dothan+peltier setup myself, even more after reading through this thread ;)

Macci,
How far I'll be able to overclock the 730 stock voltage/cooling ?
Is there a way to push the voltage without modding the motherboard ? (pin mod ?
TY
Only monitored temp in the BIOS and at 2.4G and 1.6V the coldest was around +1C but the watertemp did get quite a bit higher during the benchmarks. I'd say around +6...+10C if not higher.Quote:

TEC was a 156W Umax 15.6V model ran at 12V.
I'd guess around 2.4-2.5GHz but it really depends on how lucky you are. I'd say I was pretty lucky with this particular chip :)Quote:

Connecting CPU pins VID4 and Vss together gives a Vcore of around 1.56V. This can be done for example by useing a tiny bit of 'U' -shaped wire in the socket or by connecting the CPU pins together w/ conductive paint or wire.
all 1021-versions for P4C800/-Deluxe/-E deluxe support CT-479Quote:
well, how i can know wich one support ct-479??
Does it give the higher ram speed also at 134MHz (PCI should be locked at that boot-FSB)?Quote:

Basically from 6X to the max value the CPU supports (in case of 730 12X).Quote:
Once you are in Windows, what Multi range do you have?
Does this range vary depending on the model?
But adjusting to lower than 9X didn't work for me.
thx macci, i am ordering just now a 730, hoping it is lucky like your ^^
adabter will be here in a week or two, and for the begin i try my p4p800 dlx i have in the server :D
Well I'm not having any luck accessing the ftp server (no password) and I can't seem to locate the latest 1021 bios. Can someone link me to that bios please? :)

Awesome results macci :woot:
Looks like I'll have to pick one of these up soon for some fun :D:D
Great work Macci. :toast:

A try with a Asus P4GD1 and the CT-479 would also be interesting because of the Pci-Express support.
Or the board sucks?

Looks like Windows reinstall is the next step as I messed up the OS. 2840MHz was too much for aircooling :D
Added a bit better fan for the GPU cooler and it should be able to do near 700MHz now with these ambient temps. Might be enough for 17k Mark03 all aircooled.

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)

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 ?

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.

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)

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???
macci:
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 :)

Now that's more like it!
How big is the hit if you overclock straight up from BIOS instead of booting at 200 and using clockgen?
need to clock some 50MHz higher or so. Depending on memspeed. w/ 5:4 I can in some cases reach almost the same performance cos it makes it possible to use a bit higher memspeed.Quote:

The first very quick cascade run (w/ 350W PSU mind you :D) maxed at around 3350MHz so that would mean 11x305 5:4 for optimal 3D speed.
I saw 982FPS in Lobby low at 295x11 (3248MHz) so 999 aint that far away. Couldn't run higher than 295 bus now since was useing a unmodded 350W test PSU which only gave a memvoltage of 3.25V.
I'll take the camera, better PSU and some extra insulation for the next run :)
whaiting for yor pics macci...
i have choose a 740, i hope i can hit 3ghz 3d-stable with my home made single stage...

More pics => HERE
I was mainly running superpi today but did some quick 3d-tests with low card speed. Also had quite a wierd problems with the mobo / RAM and didn't manage to get a single decent full 3D-benchmark. One minute the board would do 310 5:4 and the other it would fail even at 295 - at one point didnt even load windows => changed RAM sticks and the problem went away. I'll probably try with the Golden P4C800-E next (this run was done useing the same old trashed P4C800).
Also had a terrible evap. contact (As can be seen from the pics...). BIOS temps were around -35C w/ full voltage...evap was at -81C :D
one full run was all I got and its at low CPU speed as I was testing the max 1:1 for this board / RAM:
Dothan @ 12x258 2-2-2-5, video 533/550 => 37485
That would be around 41.5-42k with full card speed - at 3.3GHz it shouldn't be too far from the top spots.
overclockers PRON!!!!!!!!!!!!!!!!!!!
MACCI, what's yout feel on the frost on the board? IMO, if the frost is simply on the pcb like that I haven't had problems... if it gets under electrolytic cap's then I've had melt-downs.

Very impressive macci!
lol, overclocker's pr0n indeed. :slobber:
Ricky tweak a go with these procs? Is DX9 really quicker than DX8.1 with Intels?
I really like the dothan.. a dothan @ 3Ghz with some sli action would be fun to watch!
Macci; good luck with the P4C800 tweaking/clocking..
blah..I remember my old P4C800-E Deluxe board, it managed 350Mhz FSB 3:2.. and 5:4 at 325Mhz or something.. ofcourse I managed to kill it..
offtopic: Does anyone know a i915 tweaker for mu dothan?!?
back to the topic: great job you guys... go for the big numbers!!
Good to see the cascade back in action.
Someone give Macci a better PSU ;)
i will gladly send him my neopower 480w...but im sure he doesnt need it :D
This is awsome, no doubt about it. Hopefully I will have me setup up and running next week. Will be using P4C800Deluxe -E, and Dothan 1.6GHz (hopefully at 2.4GHz ++) Will only be using aircooling but looking forward to trying out Intel once again :)
Great job macci :)

Haven't tested win2000 yet but in the past P4C800 and P4 would run best on WinXP. Might be different w/ Dothan but needs some testing :)Quote:

Your scores are always the hardest to match clock for clock.
Dothan sure does eat up fx55 130nm clock for clock....particularly on 01'.
Here are some 3d benches done with dothan at stock fx speeds(200x13),def vcore, and 5-2-2-2 on the ram. These screeenies make for good compare with fx clock for clock.
3dMark 03, 05, and aquamark are on x850xtpe boxed cooler def volts and slightly oc'd using winxp, dx9c and 5.5cats. 3dmark 01 is on a x800xtpe and is using def card clocks using win2k, dx8.1, and 4.12cats.
Not 100% sure these are the most optimal driver/os combinations btw.

Wow that is impressive and very tempting. I loved overclocking my PIII600E and Celly Tualatin (I currently have a TbredB) and a Dothan could be my next upgrade. Keep going, show the people the power of the P6 core.
