1.73 ONLY CAN GO TO 2.25
2.00 ONLY CAN GO TO 2.58
CAN YO IMAGINE HIS FEELING NOW :(
B1 cpu's are VERy POOR overclockers... that IS your problem. I had one too, a 730 ES... a B1 and they are terrible!Quote:

what is the differance between the ones that end with five and the other ones? (735vs.730, 745vs.740) which overclock better and which are newer? Thanks!
:EDIT: Nevermind i did some research :D
if it ends with 0 its new and has a 533mhz bus.

well this does 2.77 @ 1.692V @ -10C at best - can't keep that on very long 'cause I use the pinmod to get those volts and the pinmod doesn't seem to work if I fill the socket with di-electric grease (to insulate it 'cause -10C)...hmm...I hang it around 2.66 for its 24/7 speed
*checks the one in his laptop*
also B1...hmm
7x5 are always 400fsb B1 cpu's...
7x0 are always 533fsb C0 cpu's
Intel Engineering Sample 533 fsb cpu's are simply B1 cpu's with 533fsb enabled on-die, and OC poorly.
oh - so all 400fsb are b1s aye...'cause i can't use the 533 fsb ones 'cause even the 2.13 only has a 16x multi and i'm on the dfi 855 board so my fsb doesn't go too highQuote:

WHAT VOLT IS FINE FOR OC, I THINK TOO HIGH MEANS NOTHING, BUT
I DO NOT KNOW HOW MUCH IS A GOOD BALANCE POINT.
Please I hate it when ppl talk in caps ;) - I've found 1.6V to be roughly the sweet spot - anymore offers little help.Quote:

IMHO I am affraid, that Yonah & dual core ones would not work properly on existing Desktop MoBo &/or using existing CT adapter (different voltages?) & will not be any bios uppgrade ... Maybe will come out newer CT adapter (V2.0?) & bios for it, since actual one (does not support) is not suitable for running LV & VLV Dothans either (IMHO could work, just not recommended) ... :woot:Quote:

Generaly, C-M & P_M have at same Vcore & clock frequency same thermal dissipation ...
LV ones have approx. just 1/2 & ULV ones just approx. 1/3
of dissipation of medium of upper ones, since they have default even lower voltages & frequencies, also Boot Vcore (best samples!) but expencier
& could die if mounted on desktop boards/or thru CT adapter-
(not supported!), but IMHO LV ones with highest frequencies
should work & also OC w/o upping Vcore nicely, but I am not
sure ...
Hey Charlie, I don´t think that all ES 533´s CPU´s are B1 with 533FSB enabled on-die.Quote:

looking good that 2.26.. what cooling?
i wonder if LV/ULV chips are picked from the same locations from wafer 2.26's are. i remember something that chips in the middle of wafer will be usually low voltage and higher clocking ones..
so i don't see no apparent reason why LV dothans won't work with adapter.. apart the overvoltage issues and maybe asus bioses rejecting them..
anyone have LV/ULV cpu lying around and want to risk to try it with ct-479? :)
they are quite expensive.. but if you'll get for $300-$400 a chip that does 2.9-3ghz on air, that's not much..
3,1 Ghz with aircooling? If so what's the ambient temp?Quote:

hehe i dont nope much for WC ether. It will make it way more stable proabaly cpu -21c idle/ -14c load. Should be enough to make it 24/7 gaming rig @ 3G. Rememeber this is not a benching setup, box runs for as long as i like. On the pics the box is just getting assembled but you will get the point. Watercolling is setup diferent then on the pics, my heatercores are repositioned and get all the air from AC fan. You like their size :woot: they are from Mustag GT 1977 .Quote:

So far i find that 280x10 1:1 2.4.4.6 is the best 24x7 gaming setup. With realy not bad 1121FSB for descent rambandwide, ok ram latency timings @280, and realy low latency cache this cpu has which = fast read access to memory, which is the most imporatant for game performance , this setup realy shines. Cpu power = to fx55 @ 3.4 at least. How many do game on that speed? I realy dobt Fx-55 would give me same performance in my chillbox. Phase is for benchmarking not gaming. I do respect it and want one for my self to but that's not an option for now :mad: . Id love to have one day anyway thou :)

What the hell for a box is that?:D
Is it a part from an Airco? Or a rebuild fridge? I can't make it out of your pic.
How come your AM3 result is so low, I see a graphiccard that is at least a Gainward GF6800GT (@ultra speeds or a GLH edition :P)
280 fsb is idd nice for a 24/7 system @ such low voltages :)
I wish I could do that with my BH5/6 stickies :D
very nice :toast:
no condensation probs btw?
good luck for that 3G :)
hehe i hope this next pics will make it clear. It's 5000BTU AC inside the 98can cooler. If you can read on 2nd pic what does the label says :D And yea i have sold my GT to get this Dothan sys :mad: . But there is no regrets there, il get an 6800 Ultra in short while. Here is what my card scored with p4 in Aqua http://arc.aquamark3.com/arc/arc_view.php?run=421432806Quote:

No no condensation i sealed it completly air tight. Took a while but in the end it was all worth it. Drew from EOCF helped mentaly on this progect. I was runing my s478 p4 @4.3 24/7. But this Dothan is just a blessing for the box almost no heat otput compare to pressy

LOL Railer,
glad to see you take care of your old gear !!! :D
Looks quite like a mess :D
Doesn't that AC consume alot of power ? :D
hehe that pic is called mess:D
It was taken when i was setting this up. It was a messy proccess no dobt and that's not old hardware most of it went into the box, as long as i dint step on anything :p: Now it's all legite and clean.
For 5000btu AC not much. It's energy efficient. Once i use the thing for the whole monts 12-14 every day and my electric bill went up like $25. But usualy it eats like $15 a monts cause i still use it quite alot.Quote:

w00 got 177FSB on the DFI board stable; never used to be able to get past 173 with an ATI card (hates up'd AGP clocks).
Just booted at 178 - testing its stability. :)
I'm pleased to say at 177 the AGP/PCI were at 66/33 :)
no vagp mod on this atm...
ok that wasn't stable...
ok i just put a 40mm onto the nb
went further this time but looks like 177 is still tops...
hmm gone to a 6x multi and it stabilized at 178 :)
w000 stable at 180!!!
Nice box ;) I have to make me one of those so I can run a cascade realy nicely without condenation.... ill prolly never get around to it though. So iam basicaly set up now but I still have a question.
Ive read the info on which boards do what in regards to fsb, vcore and the like but still havnt seen a good comparison between the p4c800 and the p4p800's. I woould obviosly rather pay $60> for a p4p than $115+ (ebay is the cheapest seing as newgg is out. unless you know of something else). So does the p4c realy offer better performance? if so in what areas? Thanks Alot Guys!

thanks - this is really weird though, pretty much anything from 134 to 172 it slows down in windows ALOT, from what I read earlier in this thread this can be fixed up by upping the AGP/PCI but my vid card won't take anymore than 68/34. What I find weird though is at 173-180 its rock smooth.Quote:

Heh JSU that box is quite usefull with phasechange. Drew over EOCF build one to and uses with his DD unit. Best part about it you dont have to condence proof your MB or VC. That's a major problem with phase since even if you do good job on condensation proofing with -100c temps the whole MB not just by the socket gets quite cold and you can get condensation very far from socket. The most B**ch is the pci and AGP slots a bit water there spell death for hardware. With chill box it's just so much esier. Just stick evap inside and you done. Also you get the effect of cooling the whole sys like NB, memory controler,ext... = very important for stable overclock.Quote:

So p4p800se makes a great choice if you plan to use Nvidia card since there is no problems with locking agp/pci with it. It's also 1/2 cheaper them P4C800e-deluxe.
Now P4c800e -deluxe is 875 chipset board and PAT comes natural to them. You dont have to boot @ 200 to keep it. Also i belive it donthave agp/pci lock problem with ATI but if im wrong on that one you can just boot @201 fsb
and that will lock it. People here say that in general its a better and faster board. But expensive.
I got great results with P4P800se and i think it's just ezier to setup, i have not ever had the other one so i cant realy say anything about the setup. So whatever rings your bell JSU they are both great boards.
Have i summerd up major factors guys? Correct me please if i missed something important :cool:
No, your multi stays the same; option for your MoBo socket is just one pin shorthing (2nd) option something like this:Quote:

As for 3rd option (VccA rising), involves modding MoBo in your case; see PM datasheet & study a bit voltage sources on your MoBo too - here U are on your own ... :)

Yeah I know what you mean condensation wise on the agp slot. I was benching with my GPU cascade and it was only for a few minutes so i thought it was cool not to put grease in the agp socket. Well it ended up being a few more minutes (very addicting) and I ended up with a screwed up 9600p and a dead IC7.... Realy annoying ;)
I can only say with SuperPi. Last pic is mine (quite similar similar clocks, so it's kinda representative).Quote:

Basically, this way you can all the way to 1.708V and you can adjust the voltage to what you want based on the chart which Jericho so kindly hosted for me. i.e. if you want 1.6V you set in the bios to 1.084V, or if you want 1.7V you set in the bios to 1.196V, etc;

nono 2.66 is the max, I can run with a 181FSB max with a 10xmulti, 175*15 seems the best performance (cause faster ram)Quote:

Anyway, that's an unfortunate core mhz limit if you ask me. But I know after saying that, my next chip will stop at like 2566. :P
I need to know if I can use a Zalman 7700alcu with the same (simple) mod as with the 7000. Thanks much if anyone knows.
It's not the same for the 7700 and the 7000, but both can be modded to fit. I'm sure the info is somewhere around here.
Meh. i'll just get the 7000alcu. From the looks of it, these things dont do much of anything above 1.65-1.7v on air, and I think this HSF should have no trouble handling the ~80watts that would make max. (1.7/1.3)^2*(2800/2133)*27/.75
just got my new toy, 730 Dothan & CT-479. Installed my 7700CU Zalman on it which was a bit of a fiddle I have to say. Did the u wire mod too. Results are pretty good but I don't think my EB ram is very good with this setup. This is on a bog standard P4C800 using the latest beta bios (for p4c800 NOT p4c800 ed) & booting at 201 fsb.
Did a 27.40 Super Pi 32m with 2600mhz.
I'm quite happy with a 1ghz overclock to start with :)
edit..forgot the piccie!
Bit of a fiddle? Does that mean it was tricky? Also, what's the U wire mod for? I thought it was to adjust vcore... which your board should be able to do from bios.
Was tricky in the sense of getting a decent contact & trying not to do any damage to the core... So are you saying I need not have done the wire mod for vcore ? I thought you had to do the mod so you could choose vcore in the bios.
I have a question for you (since you have P4C800 & PM-730 @ 2.6ghz ), Can you make me a bench with WinRAR3.3 (or above version, under Tools/bench&hardwareTest) [816kb DL stripped ver.here: http://users.volja.net/jerman55/WinRAR33.exe ] in SAFE MODE on those settings you have in your attached picture?

(none safe mode, sorry)
@ 2.79 (11x254.1) resulting KB/s = 658 (current KB/s = 664)
recon it would fly with some TCCD >300mhz x 9
I get 702Kb/s with the rig in my sig (11 x 254.7). No safe mode
What would score a P4 @ +4Ghz ?
Of course memory b/w is critical to the Dothan!!!! I don't know WHO ever brought up the point that it was "unimportant"!!
The 400fsb Dothans on the 855gMe chipset are DOGS to be honest...
Nice scores guys (that WinRAR_bench is a kind of a real_life alternative memory benchmark, almost independant of processor core speed & type of memory; a bit less independant of FSB clock & multiplier (& best results with memory in synch [1:1]) & mainly [around 4/5] depends on real memory clock (with lower latencies & better Northbridge design, scores are better per clock calculated). I aspected worse results. Per 100MHz recalculated mem.clock you all get around 265kb/s +/- few %, almost just like my old trusty BX chipset :) , g-o-o-o-d ! :) [this bench has nothing to do with compression benchmarking or HD testing!] ... :)
well here is mine from sig...

p4c800edlx, 4x bh5, 200w pelt + 11c water, vcore 1.7v, vagp 1.93v
hoped to tweak it under 24sec, but one bh5 stick mysteriously died.
is 3.4v 24/7 too high?

Well I haven't done any intense gaming on it (10*181 isn't very fast)Quote:

173*15 is rock stable though - it's what I run 24/7 at.
with a bit of tweaking I managed to get under 28 seconds for the 1m run.. Nothing great compared to some but it's nice to break these little barriers ;)
not ultra quick ...
but at 1.4v in bios ....
heh i can make 2.6GHz with 1.196V in the bioss but at 1.212V (next one up) I get around 2.2GHz :P
Did some 3DMark2001 today with my fellow 730 on air:
Spec's:
Dothan 730 @ 2794MHz (310x9 5:4) (vcore=1.62v real) aircooled
Mushkin 2x256MB BH-5 @ 248MHz (vdimm=3.4v real)
Asus P4C800 vdroop, vcore, vdimm.
Sapphire X800XTPE @ 520/560 (stock)

click for compare
...and some SuperPi at the same speed:

I'm having some weird problems with my Dothan on an P4P800-SE. I can't boot at anything over 225fsb and in windows I can't go much higher than 230mhz because the screen freezes if I go higher. I keep the RAM below 200mhz all the time . I've tried both tha 400fsb and 533fsb jumper but they gave me the same results. I have a Dothan 740 by the way.
The board shouldn't be the problem because I ran my P4 at 14*245mhz, this was at the bios that came with the board however.
Another weird problem I'm facing is that I can run Prime for hours at 2.6ghz 1.42v real but windows is not really stable at this speed. Another weird thing is that if for example a speed is prime stable then if you up the fsb by only 1 mhz it can't even boot anymore.
Should I try an older bios? I'm now using 1009.004 beta or something like that. Atleast it has a 9 and a 4 in the name. Are other people having the same issues that I have with this bios?
Please help me, I have tried everything that I could think of and I just can't believe that this Dothan can't do a high fsb.
whats all thise REAL vcore now??? :P
my VID5 is always 0 (grounded) so anything from 0.7V in the bios to `1.196V I get 1.212V to 1.71V
For me real voltage is measured directly on the motherboard and not the readout that CPU-z or MBM gives you.Quote:

My Dothan 730 (same board..P4P800 SE) maxes out at 2600Hhz.. regardless of MP (10x260, 11x235, 12x218).
At present I accept this fact until I've tried another combo.. or I can afford another Dothan.. :)
Yes I have tried all multipliers from 6 to 13 and I still can't boot over 225mhz. I don't care that my Dothan can do "only" 2.6ghz, I'm happy with that actually. Just the fact that I can't boot or run above a certain fsb is freaking annoying. And ofcourse it sucks that I can't bench even a few mhz above a 24/7 stable speed.
I bought much BH-UTT and a DDR booster for handpicking some nice sticks for high 2-2-2-5 action but now I can't and it really, really sucks. I will try with the 4:5 divider (fsb:mem) to see how that works but I really want to run 1:1. Default multiplier is 13 by the way.
I'm going to try another bios now.
What bios are you using?

I've got a replacement coming soon, hopefully it wont have a fsb wall issue, but if it does, I'm going to take a hard look at my adapter and possibly replace it.
This seems to be the case with Dothan... you "hit a wall" at a certain clock.. regardless of MP.. At one clock (ie. 2610Mhz) it runs Prime95 24/7.. at 2620 it just freezes..Quote:

Currently I'm running on Bios 1008 as 1009.004 gave very little extra gain.. A little higher max. VCore (1.6 instead of 1.575) and of course the ability to change the VCore downwards.. and to change MP.. As long I'm only interested in max.clock.. and we have the tools to finetune in Windows I do not see the point/benefit of running this Beta-Bios..
I saw the discussion somewhere about the fact whether old skool BH5 is/isn't the same as the BH-UTT.Quote:

You said they are completely the same.
Maybe this is also an example that this combo doesn't perform well :D
Put some "old skool" BH stickies and prove you are right :)
I'm currently buring my sticks in at 250mhz 2-2-2-5 using the 4:5 divider and it works like a charm.
I have a feeling that the 1009004 betal bios first sets the fsb and then adjusts the multiplier downwards. I can do 10*245mhz from windows now but I can't boot past 225mhz and this is annoying because I just want to memtest 1:1.
I think I'm going to get another 1 or 2 Dothans and see how it goes. I just can't believe the Dothan is the problem because it CAN run at already a much higher fsb in windows than it can boot at.
It's the bios alright.Quote:

If u want to do memtest on 250+, just use the DDR500 (=4:5 right?) divider on 200fsb+.
That's how I do it.
What bios do you mean? I'm using the latest 004 beta. Did you use the 003 beta for 245mhz fsb? Or the 1008 final?
003 betaQuote:

here u go guys,
Thanks, I got it e-mailed already but you should keep it hosted for if other people are having the same problem as me.
I'm going to try the 003 beta now. You'll hear from me within an hour or so.
good its on there for our use :D
use it all u alike.
If u have any other files u want me to host ie
BIOS files. then let me know via PM.
