Anyone kows A way 2 raise vcore more? Wire mod doesn't work and mobo won't go higher then 1.425 ( 1.6 in bios )...

I guess you are looking for a vdrop mod . I`m not shure how it will work since the power to the cpu is supplied by the adapter . By the way ,don`t try soldering the mobo if you haven`t done that before ?

no, you don't need to do that. It's just a setting somewhere. remember past 220 fsb you need to up pci-e freq to desired fsb/2.2.
Remember all the obvious stuff, trun off spread spectrum, set memory timings a bit loose at first... my P4GD1 was "plug n' play" and runs fine @ 11 x 250, 1:1, 2-3-2-5 @ 3.2v 24/7 at 115 pci-e freq.

Have you found any vdimm mod for the board? Except the 3.3v rail mod?

I have done it before and I do not know what went wrong, droopmod worked but had 2 get it off and soldered it up again and didn't work anymore and vcore 0.2 lower

If it worked first time get rid off all vmod stuff and do it again from scratch. Anyway the clock in your signature is very good , from what i have seen i don`t think more vcore will help you , at least not on air .

Got Spread Spectrum Disabled and tried to loosen the mem timings ... and nothing
:rolleyes:

upping vcore and chipset voltage didnt help.. ive tried tccd and "new" BH-5. Different multis and higher pci-e frequency.. nuthing helps :( I have started to think there is something wrong with my mobos chipset, like it couldnt handle fsb past 151.

I gotta send my processor to my friend and he tests it on his P4P800.

And i have water running in my cooling system.. cpu temperature around 32-40.

If vcore can get higher I can do higher FSB with lower multi and I will put it on water :) But I will try again tomorrow or smthing, so little time these days :mad:

Nice mod on the waterblock :D . It does not look like a CPU waterblock .Is it a chipset waterblock ? How much fsb are you getting with this chip ?

It's an cpu Wb created by Rosco and DerfOne from cooling-masters for now i'm hiting a wall at 190 in 1:1 because my P4P800 Vm just deliver 2.65V for my Bh5 . Tonight i will v modd it :D

Looks very small for a cpu waterblock , i`m still loking for one that fits .

BTW,i prefer an OCZ booster instead of vdimm mod

Seems that these mobiles are all equal , it does not matter if you have a 770 or 730 it will hit the roof between 2500~2800 on air .

Thanks,

The craziest thing is the temps. Between idle and load I'm only getting about 6 degree difference. :eek: On water that is normal but on air the temps usually jump a bit higher.
08-05-2005, 08:52 AM

I just got my second 730. Locks up at the exact spot my last one did. And the guy who bought my last one also locks up there with it. This is seriously looking like some kind of intentional limit on these cpu's. But to test that I need to know how to read week dates, and I'd need a lot of people to post their Dothan's model, stepping, week date, and max prime stable overclock.

Hmmz strange problem, just fixed my vcore. So I put 1.6 on it. Can get
225*12
235*11
235*10
238*9

anyone knows what the hell is going on? ( it's nog my mem, got divider on it ). Or is this just my max? Temps are a bit high so water is going on it tomorrow or tonight, maybe then I will get higher.

I can't get my Dothan to boot with the P4GD1 :(
It does boot with a Celeron in it.
I've flashed to 1005.006 bios and the official P4GD1 105 bios and neither work.
I've tried two adapters, might be cpu? Well I don't know.

Also of note is that my PCI/AGP lock just fine no matter where I boot up. I just booted at 166 and clockgened up to 200 no problem. Also, I'm Priming 2400mhz @ 1.25vcore, so I seriously doubt that 2500mhz is a natural limit of this chip.

2500 @ 1.25vcore priming now. *Sigh* this chip would be a monster if I could get around this lockup @ 2.5

Edit: Flashed back to bios 1008 and my limit went from exactly 2500 to exactly 2400. This is getting quite irritating.

Seems to me that all these chips are very similar , does not matter if you have a 730 or a 770 it will hit the wall between 2500~2800 on air .

and as Bigtoe said :

"A dothan at 210x12 turbo mode (clockgen from 200 up) on a p4c800e+ 3500GX is upto 2 secs quicker super pi 1m test than a
san Diego at 3.2GHZ on a fully tweaked DFI with VX ram"

A lot of 2500Mhz PM are faster than some 2800 .....
08-05-2005, 08:07 PM
Lithan

Well, I'm not interested in the difference between a San Diego and a Dothan. I want a dothan that does 2700mhz+ for my own reasons (not beating san diegos at Spi).
I highly doubt it's a chip limit since It runs prime stable at 1.25vcore (significantly undervolted), and since it changes with different bios. Here's my experience so far...

1. Three different bios on p4p800se and two different bios on p4c800-e dlx. All hit a wall at 2520 or less.
2. Two different 730's. Both hit a wall @ 2520 with p4p800se and bios 1.009.004beta
3. Cooling makes no difference, voltage makes no difference, ram makes no difference, None of the bios settings I can find make a difference.

So my natural assumption would be that the ct479 has something to do with it... but I sold the first 730, and the buyer hit the same wall so if it is the ct479, it's a common issue with them.

Fully disable PAT, this helps on any multiplier below 13* on ALL my Dothan 740's at a P4P800-SE. Boot at 201mhz and see how it goes if you didn't try yet.
08-05-2005, 08:14 PM
Lithan

How do i do that on a p4p800se? I'd assume set system speed to "standard" (instead of turbo/auto) and MEM to "auto" (Instead of enable).

Incidentally, for whatever reason, my p4p800se boots just fine with "performance mode" (as titled in cpu-z) enabled at any FSB.

That said, I've tried with all those options disabled and booting at 201+ FSB. I can't even get it to post above 211 fsb.
08-05-2005, 08:23 PM
alexio

I just set performance mode to standard and boot at 201mhz and work my way up from there. I'm using the 1009.004 beta bios and this works for me. Memory divers aren't important at all.

With PAT enabled I can't go for example past 11*241 but if I disable PAT I can do 260*11 with my 2,86ghz Dothan, I have this 241 limit at all Dothans. Strange thing PAT also gives me limits at all other dividers and probably too if the chip runs at a higher fsb with the 13* multiplier but I need other cooling to test that.

I think you should use 865 tweaker and try out all timings. Have you done this already?
08-05-2005, 08:35 PM
Lithan

Edit: Correction. Bioses DO NOT change my overclock. What dropped my overclock 100mhz was changing the jumper on the ct-479 from 400fsb to 533fsb.

I'm starting to suspect the ct-479 more and more, and will probably replace mine.

Can you link me to 865 tweaker? I'll try it but honestly I highly doubt changing timings will effect anything. I'm running much much much looser than I've run on this board with 478 procs before.

I'm running at the 400fsb jumper now. I might try the 533fsb jumper but I don't think this effects my overclock.

Me too, it is very strange that PAT is limiting me at all dividers. This can hardly be a motherboard issue. I think the CT-479 has some bugs and we need a revision 2. I can't believe replacing the CT-479 will make much of a difference. This device is so simple that there can hardly be something not correct in the device. Maybe there are some bugs but this would effect every one and every device.

Guys, just to clear things up, if I get a "vanilla" P4C800, would it have the same o/cing options and performance as the P4C800 (-E) Deluxe (assuming that everything else works ok?). From Asus website, it seems that in chipset features these boards do not differ at all, but I recall somewhere people did not recommend the "vanilla" P4C800 (couldn't find that to confirm though)?

You won't have the MP option in Bios as P4P800SE & P4C800ED.
That's a major problem for dothans with a higher MP 14+.
Since you prurchased a P-M740 it's not a problemo for you ;)

yes, it is 7x5 CPU, but check his stepping, it is C0 and NOT B1, like 400FSB chips, it should do high, just depends what mobo he uses and if its BIOS allows changing multi :)

The MP option is bios depended. If your bios doesn't have the MP option, you can't change it. Basicly every board support changing MP.
Last I checked the P4C800 bios (1021b_04) didn't had a MP option.

What I've tried:
P4P800SE bios on a P4C800-> MP option works
P4C800ED bios on a ^^^^^-> MP option doesn't work at all.
As you can see even flashing a bios with MP-option doesn't always guarantee the ability of changing MP.

yes you can do this but you lose your onboard lan as the p4c800ED uses a different type than the vanilla p4c800. I tried the ED bios on my vanilla p4c800 to get the MP option but when I tried to save with the changed MP it just seemed to revert back to default of 12 so I flashed back.

max vcore, through pinmod is 1,8V, max vdimm depends onboard (or mods you do) and multiplier can be set with EIST.

I was dumb enough to mount it without pads so I can only blame my self.
I didn't get any good contact either.

MrLobber, yes P4GD1 is fully locked

Urlyin, I don't need to cause I could boot with the adapter :D I got a 16 bios or something in it and it worked flawless :P

Yes. Removed the clips, dremeled the edges off the bars they had rested on and mounted them again underneith the bars with a couple washers each. Mounted about eight times. Chipped core second and fourth time. Got a heatspreader off a 1.8a now, but I've already moved to a zalman so I could put the xp-120 back on my A64s.

Stryg ... you can add Systool to apps ... it can change multi, FSB , memory timings and find max oc, plus monitors CPU temps from on board chip ... here. Works with my PM 750 and P4P800-E ...

Do i need that vcore u-wire mod to get higher vcore in p4c800-e dlx mobo?

i can put 1.6 in bios. and rise it whit vcore mod. but but. is that u-wire mod needed in that mobo?

Here is one tip on how to cool the dothan with water+pelt, very easy installation if you have the parts.

Swiftech MCW50-T with parts from this heatsink.

http://www.nordiccrew.com/crusader/MCW50_dothan.gif

The zalman 7000/7700 have the same parts, just rip 'em off. On top of the block, I have a rubberpad so that the retention wont slip. A 80W pelt should be able to keep the dothan cool dont you think?

My Dothan 730 stays onder 50 with full load with water and 1.6 vcore. Is this good? Or should it be lower?

I don't get why everyone's temps are sooooo high. I get under 30C @ 1.6V with a MCX159 chipset air cooler and only a few degrees above ambient on water.

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.

Ok. My 730 boots whit 12x203FBS and its stable whit that. but thats all. i cant set any higher or its not stable anymore. i had used setfsb program to set clocks in windows. temps are 33C idle and 46 full load whit 1.6V.. i had tryed whit lover mems setting. still :banana::banana::banana::banana:ty clocking. any advices?

You could have reached the limit of the cpu. Unlucky if you have. Are you running turbo mode ? Try running standard if you are, it seems to help mine clock more reliably. Is it just locking up ?

no turbo mode. all standard. looks that im extreme unlucky whit overcloking cpu:s... yeah. it just locks up. looks that 1.5->1.6vcore dosnt have any effect. looks that im going to sell this and get new one and hope the best

and it runs something like this. 9:250. 10:225. 11:215... so its almoust about same speed as 12x201.

i had done vdroop and vdim mod. so vcore is stable... looks that i just dont have luck whit overcloking. or im doing something wrong.

Try finding the 1M breakingpoint with every multi. That should give you a fair idea of the CPUs max.

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.

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?

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.

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).

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:
