Maybe the 875 board doesnt like TCCD memory (which i presume you have).

God don't say that ! I've just bought some TCCD for my p4c800.. I thought it was good stuff for the 875 chipset?

I dont know that for a fact, I simply suggested it.

Oldschool BH5 and 865/875 simply loves each other like mad. Thats a fact.

29s whit 1M is the fastest what i can get. 9x270 gives that. 10x250 givest that too. but those are not stable clocks... so i think that i stay whit 12x203 and wait for water block for northbridge and check does that help at all... "passive cooler is extreme hot"...

and my mems are kingston hyperX 460ddr 2-3-3-7... not BH5. dunno what chips those have. and vdim mod is for 3.3v

Edit: i noticed weird thing. when setting 204-205FBS. my wlan "usb" goes really slow. downloads drops 100kb/s -> 10-15kb/s... when i set it to 206 its normal again....

ok first of all i'll put my rig that is:

Dothan 750 + CT-479
P4C800 E- Deluxe
2x256 old bh-5 + booster
cooled by vapochill LS

made the u-wire mod and flashed with last bios 1023 , vcore is set in bios at 1.6v , also the temp in bios displays -20ºC

i managed to achieve 3030 Mhz (12x152) at 2-2-2-5 3.4v

so here goes the rare issue , i could get 24s in super pi 1M , thats ok , but when i pass 2M or 8M the performance drop , this example should explain better

Dothan at 3000 (250x12)

1M result--> 25s
2M result --> 1'04s
8M result --> 5'07s

San Diego 3700+ @ 3230 Mhz (320x10)

1M result --> 25.500s
2M result --> 58s (@3216 Mhz)
8M result --> 4'47.500s (@ 3210Mhz)

Dothan at 3050 Mhz

1M -->24s
2M --> 1'02s
8M --> 5'01s

i don't get this.... best overclock on San Diego and i can hardly get 25.433s in 1M , i've got to relax clocks to pass 2M and get 58s , why Dothan is faster in 1M and slower at 2M and 8M ???

the temp is always the same according to speedfan , even on 1M or 8M , what could be wrong??

saludos and forgive my bad English

During the small calculation of 1m most/all data fits in the 2mb L2 cache of the dothan which makes it faster because it has twice the cache of the San Diego. During longer calculation the dothan loses it advantage because it has to use the system memory more during the calculation giving the San Diego an advantage with it's bigger raw calculation power and ondie memory controller giving lower latencies.

Good insight, I was wondering what caused that issue myself and that seems logical. My 730 hits a wall around 213x12 :(. That's not TOO bad but i was hoping for at least 2.6ghz. Best SuperPi I got was using 2-2-2-5 @ 208x12 which gave me 30.8 sec or so.

I agree to some extent, the Dothan holds about a quarter of super pi 1M in it's cache whereas the Deigo holds 1/8 so that gives the dothan a major advantage, but in more memory intensive tests (such as 2M, etc) the low latencies from the ondie controller allow it to pull ahead. However, what I disagree with is the statement of bigger raw calculation power. I'm inclined to believe the pM has a better raw calculation power than the Deigo at any given clock (I mean as in both at the same clocks). It has a 9 stage pipe, compared with a 12 stage on the Deigo. It's not jsut the cache that makes it faster. I mean, take a series 6xx vs a deigo at 3GHz. The 6xx can fit double the amount of the test in its cache yet the Deigo will probably do it twice as faster regardless 'cause it has a much shorter pipeline. That's just my 2c.

Yes I agree that clock for clock the Dothan has probably slightly more raw power. But this was a comparation between a 3ghz Dothan and 3.2ghz San diego. I think a SD at 3.2ghz has slightly more raw calculation power than a Dothan at a 200mhz lower clock.

Nice with this thread :D..
I am just waiting for my 750er, and i need som info - do anyone knows the distancepieces, which can make it possible to mount a watercoolinghead through the 4 std. mountingholes?

I have i picture, but i need some dimensions! Does anyone have got these?

Hi men. I have tvwo qustions:

1.what is bootblock "trick"?
2. Can I use Dothan CPU on ASUS P4C800 DELUXE rev. 1.03 (non P4C800-E deluxe)

1: Use the search function as this has been covered in depth.

2: Yes the none -e supports dothan, but will not allow multiply adjustments from BIOS>

When overclocking the PM, do the jumpers on the CT-479 matter? I OC'ed my 750 to 2.85g. I am getting ready to replace the stock cooler with a Zalman 7000. I removed the jumper just for fun ... did not seem to make any difference???? Can they be left off??

SuperPi @ 2.80 is 25.82sec.

Maybe the b1s run cooler than the c0s...

*checks*

well Intel says the C0s arelike 27W whereas the B1s are 21W, don't know if that effects it too much once o/ced.

The TDP is more a guideline for sys integrators than a real indication. And is the same for all the 533 family (from 1.6 to 2.26).
IMHO there isn't a different at all in dissipation, after all the voltage is the same as B0. Probably this different results are just dependent on case cooling, Tambient and overvolting (well, and termistors).

Umh.. interesting found.
easier to mod in this way, just cut the jumper pins, no solderings or low profile minijumpers.

The Dothan has a comparatively weak FPU,....after a certain point (Pi @ 2 meg), it's larger cache will lose out to the A64 cpus.

It makes sense, but not explains why it still kicks A64 in games. I guess games use the same type of calculation .

Maybe I was doing something wrong but my Dothan @ 2.6 (260x10) was way slower in 3dmark01 than a Venice I was running between 2836 and 2862....especially in nature. Of course if I had a better Dothan that would run at 2.8+, I'm sure it would win. The substantially lower nature fps I got with my Dothan seemed to bear out the weaker FPU thing. I should have ran the Venice at 2.6, as well and just compared the '01 nature fps.
Did get good CL fps though. :D

hum , it is quite strange because Bigtoes running a P4C800 and a Dothan at 2500Mhz /220@2-2-2-x seems to be much faster than that . Here is a test of a Aopen board at 200fsb running a Dothan at 2.1 (slower than an Asus ) . :confused:

Don't get me wrong, I like the Dothan/Sonoma cpu and I'm really happy with my P-M system but I was getting better '01 scores with a 200-300mhz faster Venice. I can't expect too much from a P-M that maxes at 2.6 with 1.6.vcore.
Another thing....I think this has been mentioned before but my Dothan feels alot slower in windows (moving files around, opening and closing apps, etc.)....not bad but a little annoying at times.

I understand you . It is basically a gamming processor , maybe you are felling the difference in bandwidth . How are you running at 2600 ? From what i have seen low timmings are very important .

Can anyone here with a P4C800E-Deluxe go lower then a vcore of 1.5? Bios 1023...
08-27-2005, 01:45 AM
Marlowe

Two questions:

1. Are there different steppings? Wich tend to overclock best? (this should be included in the front page)

2. Using a P4C800E Deluxe with the latest 1023 official Bios, use of software to adjust FSB/multi/vcore is not needed since all this can be done in bios, CORRECT?

Thanks! :)

1 - There are 7x0 and 7x5 cpus , the 7x0 overclocks better . Other than that there are two Intel Sspec number for each kind of processor (eg : the Pm 770 can be SL7SL or a SL7SP ) . For Dothans people usually ask for packing date and/or place it was built (eg :Philippines /Malaysia ) . There is no database so far for the best clockers . BTW , it is not a bad ideia since all other processors have one in this forum :D

2- Partially correct , somethimes it does not boot at high fsb and people change do it in Windows

Okey! Continuing on the stepping subject:
I found these two types of the 1,73 GHz '740' at the Intel site:

SL7SA 1.73 GHz 533 MHz 90 nm C0 2 MB 478 pin PPGA
SL7S8 1.73 GHz 533 MHz 90 nm C0 2 MB 479 pin H-PBGA

The package and number of pins are different! Surely this must have some effect! At least do they both fit in the same socket and hence fit in the adaptor? Are there any information on wich version tend to overclock best of them? If not, are there any cpus built in a certain production date and/or fab that is known to overclock higher?

Just want to make the best out of my money you know :)

ran some 3d01 for you, this at 2.4ghz, 200x12 with the 6800Ultra at 466/1.3ghz, the wife uses this machine now so i can't push it to hard.

see how this compares, remember you need a 6800Ultra at the same clocks to do apples to apples ;)

Both are socket 479 , this is the Package Type you are looking . Yes both will fit in your adaptor . There is no info regarding best clockers , cause for some reason we don’t have a database . We have for Venice/ San Diego / Winchester …..basically for AMD stuff but not for Dothan :(

Hello DrJay! Sorry to hear about your poor results! :( What cpu and stepping are that?
Does anyone know of the steppings on one or more dothans that has clocked well (2700 MHz ++) ?? :)
According to Intels site there are only two different steppings of each type, so there aren't many options.. :p:
But if one package method are consistently perfoming better than the other, this is very important.

So the ones we put in our adapters are the PPGA versions?
So there are actually no steppings to choose from with the dothans.. only time and place of production..

That just makes everything so much easier! :( :stick:

Yes - PGA are the ones you want. Worth checking if you're thinking of picking a chip up 2nd hand (e.g. from ebay) and the seller doesn't have a picture / enough info (for example someone was selling 5 x ULV 900MHz Celeron Ms on ebay.co.uk today but they were all BGA - or I would have snapped them up ;))

Trick is 200fsb and turbo mode with BH5, only clock with clockgen over this.

you guys witht he P4p or p4c boards, unless you are running 250fsb 2.5-3-3- you would do better running 200 with turbo and a slight clock in windows, trust me ;)

Wait, the P4C800-E DLX PAT doesn't run above 200 FSB in the BIOS? I thought that for that board everything works with PAT. Getting my board in a week and planning on running 220 FSB but not if PAT/turbo isn't working. Also, would 220 at 2.5 CAS be worse than 200 at 2 CAS performance wise in gaming?

Ofcourse I've got Asus CT-479 adapter. I tried 400/533 jumpers on CT-479 - no effect :(

I checked on DFI-855 MGF too, not runs :( But DFI doesn't support sonoma dothans officially

Thanks for running the test Bigtoe. Unfortunately, I can't use it to see if my system is hosed as I don't have a comparable vid card. Closest available to me is a 6800le w/ 12 pipes.

[QUOTE=Rovtar]i have water cooling :p

as i said earlier, cool it BETTER - add peltier to that for a start and i am 100% sure with one 226W pelt you will brake not only 2.7 but some more barriers :D

i don't think that cooling is the problem beacause full load temp. are 50 °C max

exactly - 50C is high - my 745 runs at 52C load with no heatsink overclocked to 1.94 - if i want to reach the 2.6 range I need to keep it below 40C or it'll reboot.

btw ur sig says 1.9 - there are no 1.9s; the 750 is 1.86

3dmark03 is a vid card test - cpu has very little to no effect on the last three tests.

I get a boost of under 20 marks from 2.4 to 2.6GHz with an x800xt.

i know, but i expected at least 100 points from 200mhz clock...

Try using a P4 or your C-M and flash the bios to the latest verison. Then replace CPU with P-M and it should boot.

You then might need to REFLASH the latest bios again with the P-M.

I had to flash my P4C800ED with 1009.x bios with a P4 cpu first, then reflash with P-M after it booted but showed bios checksum error. No problems so far and still tweaking.

you guys witht he P4p or p4c boards, unless you are running 250fsb 2.5-3-3- you would do better running 200 with turbo and a slight clock in windows, trust me ;)

As bigtoe said....... :)

NOT booting with 201MHz fsb BUT with 200MHz fsb.......With the 201MHz fsb you lose about 300+MB/s Memory bandwidth with the BH chips..... ;)

Also comparing a P4P800-SE with a P4C800-E, it's like the day and the night.....NO compare at all.....875 chip shows it's teeth on P4C800-E mobo....... ;)

hmm

problem

using the p4p800se

and when i boot @ 200 it's faster but the AGP/PCI aren't locked, if I boot at 201, it's ALOT slower, but the locks kick in

hmm

Try to clear C-Mos and do it again......It happens to me too with the P4C800-E sometimes...... ;)

Hmm as the P4C800-E is discontinued, what would you recommend instead if I cannot snap up a P4C800-E quick enough? P4P800-SE?
