Make sure you press F5 as soon as installation begins and install the 'MPS Uniprocessor PC'.
28000 sounds nice. I've been through 3 Dothans so far and none of them even come close to 2.8GHz. :( One of them can't do 2.5, the other falls below 2.6, this one used to be able to do 2.7 before I chipped its core. :-/ Perhaps the fourth time around....
Thanks for that Gautam.

Just cranking her up. Hitting 2832 Stable ATM.
Won't do 2850 stable though, but my P4C800ed is dropping bad to around 1.54v under load(1.6 set in BIOS). So need a droop mod and maybe a Vcore too.
I also have some PC3500 BH5 corsair sticks that I can use for a fast run.
As for the ballistix. Just ran 5 full loops of memtest(All tests) @ cas2,3,3,8 PAT on 235mhz :)
Pentium M 740
2x256MB OCZ BH-5
P4P800SE (droop mod + 3.3 = vdimm)
Prom mach2 R507
Going to do a vcore mod tommorrow to get higher. The proc doesnt seem to be a very good one but its nice for now.
The first screen is a bit f*cked but srry about that :p:

@ The Doctor : I see you have a digital uniMeter; did you maybe measured real CPUs supplied Vcore (Vcc) & how? (to compare it with Bios/monitorProgram readout)

and one more .this is a24/7 set up :D
A random though here on the 400MHz and 533MHz FSB chips and their overclocking abilities... Has anyone checked cache latency between the 2? (At the same FSB and overall clockspeed, same RAM, ratio and timings, etc)... I'm wondering if there's any difference between the two and that's why the 533MHz chips can clock to higher FSBs?
Edit: Ignore that - just realised that it would really show up in the performance if the 533MHz parts / C0 cores had a higher cache latency (don't know what I've been smoking ;))
Here's an issue I just found happening with my 730.
I seem to have hit a FSB wall.... regardless of multiplier I cannot boot (not even a post) at >247 fsb.
I can boot at 247 X 11 with 1.55V in bios. Thats not totally stable, but I can atleast pi 1M at that speed. But at 248.... no post. Strange thing is, I can and have been booting at 237 X 12 as seen in my sig.
So I figure ok, lets find the max FSB. Now this is on a P4C800E that did 275 fsb on my 14 multi pressy just a few weeks back. 10 X 250 = no post, 9 X 250 = no post, 8 X 250 = no post, 8 X 245 = no post...... Have not tested lower.
So WHY can I boot at 11 X 247, but 8 X 245 will not post at the same vcore :confused: My ram can handle up to 250mhz 1:1, but even with a divider I still could not post at 250 (ram at 200).
I have not tried clockgen yet, well not fully that is. I booted at 237 X 12 (max stable so far) then clockgened up to 240 X 12 .... seemed ok until I minimized clockgen .... locked up.
Questions:
Most important: I have the 4pin P4 connector plugged into the mobo, and I am feeding the adapter with its 4 pin power connector as well. Does the mobo power connecter need to be there? or could it be hindering anything ?
Is there any particular mod that should be done to the adapter itself? (have droop modded the mobo a while back).... strange thing is, that while there does not seem to be any droop, I set 1.5 in the bios for instance, but yet the sensor reads 1.47ish.... It used to overvolt at idle.... 1.5 would be 1.53ish, so that I find strange, but I figure the sensor is just reading wrong. I have not done the U wire mod (using the new beta bios for vcore / multi adjustment)
Is 1.6v safe for a 24/7 system ? I have been hesitant to go over 1.55v, but I have tried 1.6 for a few mins... still no post (cooling in sig)
I just don't understand why I cannot boot at higher FSB at low multipliers..... I guess the cpu just doesn't like higher fsb, but why does 11 X 247 work, but 8 X 245 not :confused: :confused: :confused:
Thanks for any input :)
@ The Doctor :
According to the pics, measuring was done on Mosfets on MoBo, you should have done it on the adapter with temporary very small HS provisorly mounted-no fan (to have access to adapter onBoard Vcore regulator) @ stock clock speed, I am sure the values would be different than from MoBo ...
@ Frozendeath :
The mobo power connector does not need to be there! (adapter has its own Vcore regulator feed with electricity by that "floppy" plug ... To rise the Vcore, IMHO you have to do a "VID pins wire trick mod" on the socket of the adapter & do not go over 1,6V ... If this does not help, means that adapter onBoard Vcore regulator can not go higher much ... find Intel datasheet for example [C-M] 30311004.pdf (p#16&36) for Dothan pins & Vcore definition ...
I'm VERY VERY upset now. My 730 hits a wall at 210-215 just like my 715 did at ~166. There is absolutely NO WAY to stabilize above 210-215 on either p4p800 or p4c800 with any of the 2-3 bios I've tried on each. This would be an easy 2700mhz chip if not for this issue.
Bah!

now i just quoted the rest because i may have some input for you there.
anyway. i have somewhat the same issues. multi 8x is a no go, but then
again a bunch of guys around me have the same problem. you can select
the 8x multiplier with almost anything (i didn't try anything below 200), but
rest assured, that it *should* not work. it seems this is some kind of bios
issue. but a general one, as it affects p4c800-type boards as well as p4p800
type board - i am running a p4p800-se.
anyway, i found 9x to be the best multi available for some aircooled high
fsb-action. so far i had it up to 311 via clockgen. 8x doesn't work, 7x can be
selected, but magically switches over to 6x. so the multi-settings left are
6x, 9x, 10x, 11x, 12x and whatever multis you have available via your cpu.
i prefer the higher ones 755 and upwards...
you may try to boot at 8x133 or 8x166 - shouldn't work... so don't bother
with 8x - even selecting it via eist in windows makes my rig crash before
i can say wow...
with my p4p800se i can boot at 250 - 9x 10x, whatever.. maybe a single
mhz more, but 252 is a no go. doesn't matter what kind of mem-divider or
pat-setting i'm running. so live with it. whatever your max bootable fsb, be
happy with it - it's not the end of the road, as i found out via a couple of
days of testing and some good hints around here.
btw another thing regarding your overclocking trials from 237x12 towards
240x12 via clockgen. it might be wise to drop the multi a notch - either via
setting 11x in the bios options or by dropping it via eist in windows. trust
me on that one. unless you run 1:1 and your memory craps out on you, you
should be able to rise the fsb a good deal above your max boot. sure there
has been the occasional "bad" board that won't do much more anyway, but
in most cases you can go higher using clockgen.
a word of notice regarding clockgen. use small steps to up the clocks if you
want to shoot for max-fsb. i usually boot at 10x250 or even 9x250 (on going
for >300 fsbs) and then - knowing i can go beyond 300 - i up the fsb in steps
of about 10 mhz til i am at ~290. like 260, set, 270, set, 280, set, ... when
i reach 290 i use smaller increments, until i'm in the killzone where i only up
it by clicking once, max twice on the arrows to up. then set -> bench spi1m,
next, ... on first trying for max fsb, i went from 250 to 30x in increments of
1mhz fsb... took 30mins to one hour to finally get there ;). but sometimes if
you make to big a step, the sys locks up even if it *could* run with the
selected fsb-clocks (& overall clocks).
regarding the p4 plug. leave it plugged into the board. it's there for a reason,
so keep it that way, it's better and all...
regarding 1.6v 24/7. well writing this reply i don't see your sig ;), but anyway,
i would make that choice depending on what your temps are loaded/unloaded
- i try to keep my rig below 50°C loaded.. but then again i'm still only using
the default asus-heatsink. my 24/7 clocks & voltages are this:
266x10 @ 1.52v (or whatever that exact setting in the bios is). it works with
1.51x, but i usually up it one notch for better stability. that way i can run
it all day and all night. on benching i go up to 1.6v and ~2.8ghz (barely
stable enough) resulting in about 54°C loaded, but i wouldn't run it at 1.6v
24/7 with that stockcooler. using a half decent waterblock, like that zalman
zm-wb2 (that i still need to find over here for a decent price) or some kind
of phasechange, i wouldn't think about it. with phase i would probably run
upwards of 1.7v if it would yield significant gains...
true!!! 8x doesn't work on my P4C800... 9x++ work great!! Sky, your 311fsb, is that 1:1?? The best I can do 1:1 is 295fsb,,, with some G.Skill.Quote:

btw charlie, do you still use the booster or did you vmod your p4c? i'm asking
out of curiosity, as so far no one answered my question whether hooking the
3.3v line direct to the dimmslots offers a higher useable vdimm compared to
doing the oldskool vdimm mod using lm358 pin 4 to ground at same 3.3v line
settings.
i imagine it *could* be like this:
- 3.3v soldered straight to the dimmsocket offers 3.3v vdimm (all the time).
- pin4 to ground @ 0 ohms on lm358 offers 3.3v -0.10-0.12v (due to chips)
is it like that? if so, i'll do that 3.3v to dimmsocket mod, because 3.3v @3.7v
just to get a useable vdimm of about 3.47-3.5v under load is bad. and this
makes benching a nightmare.. you never know what kind of voltage your ram
gets at any given time :(
even with most of the 400 fsb parts crapping out at fsbs of 16x-18x ish, theyQuote:

more fsb (almost twice that of the 755 :D).
overall the newer ones are the better choice, but (imo) only for the higher possible
fsb. the chips i have don't differ much in terms of general overclockability (see
above)
After some tweaking i loosened up the preformance setting wich in my case meant the clock by clock speed was reduced slightly but the cpu could clock 50/60MHz higer (other 20MHz were from vmod).

I found the same thing you and highlander did. I cannot post at 250 X 9, but via clockgen I can run 280 X 9 spi 1m stable, 285 locked up, but I was only at 1.525v so I bet if I raise vcore I can get into 290 + FSB
So yes there seems to be a major bios issue, some sort of wall that when we hit it there is no way to post at even 1 fsb above said wall.
The strangest thing is the wall for some is 217, 230, I'm at 247....
Thanks again, hope asus looks into this, maybe that is why bios 23 is beta :p:
Isn't that the one you showed before (in your previous post)? :DQuote:

Vdroop just stabalize your Vcore when you system is under load. And doesn't let ou choose the desired Voltage.
But after I've done the Droop-mod it overvolts my Vcore with +- 0.04V (1.618V instead of 1.583V)
Exactly 1mhz is what i found too.Quote:

But although the 23beta is possibly to blame, at least the multiplier option works. Hopefuly they will fix it.
The reason I believe it to be a BIOS problem, is due to the fact I also get problems with mem timings.
If I boot and run memtest- then change Cas/tras etc Its error free.
An exaple is 233 , I still can't post lower then cas3,3,3,7 with Full PAT, yet i can adjust to Cas2 in Memtest and run 9hours full runs error free :confused:
Ahh interesting info on your mem timings as well.
I have not tried that yet, but I will do so this evening. I was running 5:4 on the mem with timings loose enough to push any problems onto the CPU as I upped the FSB.
But I will try a some tighter timings tonight and see if the no post happens to me as well.
Its all very strange, other chips in the past, most times they will post but not boot windows, or crash when they hit the desktop or whatever. Ususally add more vcore and it becomes stable. Finally you max it out and back off a little. But I have never seen this, where the chip CAN do more but something (bios ? mobo? adapter?) will not allow it to post despite its stability in windows at the higher settings.
I should also point out, that I have tried with 2x256 Bh5 & 2x256 BH6 to see if it was due to the capacity of memory, as it had been said 2x256 may give better boot FSB.
Exactly the same results - no post at 246 regardless of multiplier.
Also I can adjust mem timings in Windows and run everything there stable too - so its goto be the CT-479 & BIOS>
@ Frozendeath :
@ charlie :
& @ others too ...
The problems with initial lower Fsb boot (no mater the Vcore set) but if clock is rised in Windows later goes higher is in fact Bios/design problem according to Intel´s datasheet !!!
Yes, in electrical specification there states for Vcore: Vcc,BOOT .. 1,2V (-/+ 5% margin)!!!
This voltage is controlled by 2 output control pins on the Cpu (VssSense+VccSense) that tell MoBo that all is Ok before attempting other Post procedure, no matter what actual Vcore is set-that looks like kicks_in determined by MoBo/Bios later when POST is finished! So that Vcc,BOOT too low Vcore at begining is the problem. Same is why MoBo has to be flashed before mounting P-M Cpu on it to recognize that states (if not flashed looks likes no boot at all except on ECS-P4IBASD (i845D) MoBo).
Yes guys, I´ve done today my "homework" by deeply studying datasheets whole day [http://developer.intel.com/design/litcentr/index.htm] & I am prepairing a post with more possible enhancements & troubleshooting ideas to better OC {"Me brainstorming, You make modds!" :D :D :D ... way, like I did it on times of Tualatin_on_BX mod breakthru on MadOnion/Futuremark thead more than 3y ago) also for some other sites forum Celeron-M thread guys :) ...
So how to circumvent that boot 1,2Vcore problem? Hardware way Fixing Vcore on the MoBo & maybe some of those other 2 mentioned pins (or both) "fixing" by adding some pull_up/down resistor for forced termination or isolating them (modding the adapter or MoBo further-need of also P4 datasheet for last!) That way IMHO could the MoBo or adapter be tricked to supply @ boot higher Vcore immediatelly resolving that lower Fsb problem on boot!
The other solution IMHO could be by isolating in socket the E4 pin (PwrGood) & connect it via "wire trick" to a non isolated first (not so) close VccP pin, to trick the CPU & MoBo that all is Ok, so that MoBo supplies full Vcore@boot to a CPU & boots anyway. Same way we did it for Tuallies on slotkets time ago to enable booting ...
I also checked fotos of that Asus CT-479 I got from different sources: There on it are 2 linear voltage regulators: bigger one for VccP (1,05V -/+5%) for signal i/o Cpu stages & smaller one for i/o chipset GTLREF-erence (0,63V -/+1%) = electricity source for that is from that additional "floppy" power conn. like for other electronics there on it, while Vcore source is from MoBo P4 socket ...
And you know what that means? It means that Intel reverted back to 8y ago (to P-1 family way) for supplying Cpu with 2 main voltages-differential supplying (like last ex.P233mmx & before) again !!! One for strictly main core & one for cores i/o signal stages! Thats way you need that Asus adapter (also because too may pins are differently placed on P4 & P-M Cpu, especially a bunch of Vss and Vcc pins interchanged). P4 & other last 8y Intel CPUs have single power supplying (like AMD too, starting with classic Athlon till now) ...
Did I make my homework or didn´t I ? :p:

Now that we know what it is maybe the bios code could be extracted and injected into IC7's or other boards? Or vmods might be the easier way to go since it seems they might need one anyways? Nice work Spajky ;)

Nice work Spajky, what this basically means is that the adapter is not able to supply atleast 1.14volts the instant we call for it to boot at higher FSB (each adapter probably varies slightly, and thus the various "FSB Walls" we are seeing).
Thats great info, now where do we look? The bios is what is monitoring this, but the adapter is the source. hmmmmm..... Bios modding or Vmodding....
Maybe a resident bios guru could take a closer look ;)
See my previous post again, I right edit it (added another trick!) :)
Spajky
If what you say is true, then it must also be try the inital load with the default multi since changing the multi has no effect on the FSB wall.
If the max boot OC for a 730 is 12*210mhz = 2520 mhz
then changing the multi in the bios "should" yeild 10*250 = 2500mhz as a new max..... should it not?
Of course, I may be out in left field here since I have no idea what I am talking about :D
Quote:

Changing the multi to 9 does not allow me to boot at 315 X 9 = 2840.
In fact I cannot even boot at 250 X 9. So that does indeed confirm that the multi in no way affects the "wall"
The question this brings up to me is:
When does the multiplier get applied to the cpu? If the set vcore does not kick in immediately, how long does the multi take to be put in?
For example, trying to boot at 9 * 265 is actually like 12 * 265 causing the initial load to be high enough to pull the 1.2v "vcoreboot" to a no post flag?
For that to make any sense then the wall must hold for every multiplier, thus for me, I can boot 12 * 237, lets say that 240 is the magic wall number..... I step it down to 9 * 250, it still won't post as its stitting at 12 * 250 the second I power it up, causing to much load for the voltage regulator to keep up until the vcore set in the bios kicks in...
Just thinking out loud here ;)

I too think this, and this is why ppl are able to boot with different FSB values before they hit the wall. I guess it will depend upon
a)cooling
b)CPU's default multiplier.
E.g I can boot with max 245mhz FSB with an m740, if I were to change to a m750 (that topped out at exactly the same mhz) I might be down to 210mhz wall.
@ ALL : Could be that you all are right, about that bios boot problem - MoBo boots (when Bios checking hardware for first few seconds on AUTO settings (bios boot_block defaults) & only than a bit later applies settings determined in Cmos; many boards arround have this issue as I see ... so previously set multi/Fsb/core_frequency & Vcore are not engaged instantaneusly first moment!
Guys, Abit & their Bios manufacturer made stuff to be safe for use for normal users (NOT OC-ers eXtremes), so do not think that there would be available some "enhanced" bios uppgrade for you from them! You need to find someone else really capable to hex_edit the bios code & prepare you a "hacked" Bios for your purposes to re-flash the MoBo resolving certain problems. IMHO this would be the best way.
The next "safest" way would be to try that "dirty Vid Pin wire trick" on P-M socket/Cpu to trick the MoBo of higher boot Vcore if works. If does not, the next step would be leaving that dirty wire mod trick engaged & again reflash Bios with the same Bios version. Could happen that then you will be having a default Vcore higher than before & could be raised in bios even more (maybe up to 2V-attention!-too much!). This trick worked many times in the past, maybe will work also here. Here you have an mine example of tipical FlashBoot diskette ready to be than custom modified if works for you (read_me inside,file): http://users.volja.net/jerman55/FlashBiosFD.zip
The third "safe" way would be that my mentioned Hardware way Fixing Vcore on the MoBo. But that also involves some reading & knowledge too: Vcore Mosfets on the MoBo are driven by an output of 8-bit input digital PWM chip there, which gets combinations on its state binary pins by another smaller digital chip, which gets serial data on MoBo´s i2c (SMBus) data link from Bios (that last chip on old boards with only jumpers or microSwitches for Vcore wasn´t there needed)! Find searching on Google datasheet for that mosfet driver chip on your MoBo, to know which its pins to solder (or terminate with pull_up/down resistors) to a 8-way microSwitch setup. (not sure if w/o need for cutting traces near that chip on MoBo will work, maybe will!). So instead of controled Vcore by Bios, you have a set of switches, which is IMHO better than have on MoBo totally fixed just single Vcore! So that microSwitchSet controls the input logic states of a Mosfet driver chip to procure "right" Vcore to the Cpu!
The forth "safe" mod would be that (added later in my last post on previous site) "PwrGood" trick; see an example picture on my site under comp/mods, how I did similar stuff for Tuallies; the wire is fixed with transparent sellotape & goes shortly into a hole of an orange isolating small tube used for isolation not to tuch internal contacts base (to prevent any electrical shorts-"Electronics runs on Smoke; if it comes out of it, its a BS !") :D :D :D ... You better practice modding/opening socket before on some dead slotket/socket/MoBo, to make it later "tiny", nice & clear & not "dirty"! Do mods on the table not already mounted inside PC!
The last one less safe is the first socket/2-pins mod I proposed (VssSense+VccSense), but you have to study yourself datasheets further before attempting that. I hope that you know, that all these my modding ideas can be tried at your own risk, nobody guaranties you success & many times things can go "south"; sh1t happens! :) But usually people with guts have at least some success (not always)!
Further ideas for better OC will follow maybe already today later !

i tried that with ic7 .. injected all dothan microcodes from aopen 915 mobo (for some odd reason, dfi mobos don't have microcodes for c0 step).Quote:

btw, does mobo need a "confirmation" about vccp and/or gtlref, too?
with pent M and adapter, they are naturally too low or missing (because adapter generates 'em and mobo gets too low feedback voltage or none)
hmm... mby i'll try to tinker with it this weekend as i still haven't sold my ic7.
i kinda hate asus and ami bios, so i'm interested :)
Yes, this makes so much sence to me, I bet it's the case here. I really hope there will soon be a cure for this through a new beta or hacked BIOS or something. My 730's max is at about 2600MHz and that would mean my max boot FSB is a bit under 220MHz.. Haven't tested this yet since I've been booting at 200 or 201 but I'll bet.Quote:

But this IMHO does not resolve the Vcc,boot problem! It looks like just helps keeping Vcore stable under load, but IMHO that is NOT needed for Dothans, since even if max.OC-ed they do not consume more than 2/3 of current like P4 can & does!
So if droppin´ Vcore under heavy load exists, probably there is some not good Caps or MosFets overheating problem (maybe also PWM controler overheating too; you know what to do then :) )
@ caater : dothan microcodes injected into bios code alone does not help much (only post show propper Cpu) but after recognition of Cpu, other Bios routines coded inside bios do other job (involved with CPU recognition) & that has to be hacked too!
[Q]does mobo need a "confirmation" about vccp and/or gtlref, too?[/Q]
IMHO not necessary, but depends on MoBo design/Bios code; looks like on Asus boards it does. Thats why I proposed modding the adapter as an alternative ...
But guys, are you sure that you have a locked PCI/Agp clock inside bios enabled? If not, this could be also a problem with all kind of peripherrals like integrated audio, Lan, firewire, video card, IDE & especially Sata controller not tolerating too much out of specs clocks! Try to disable temporary ALL except FD controller & insert an old PCI graphic card just for test & start a PC with a Dos/W98 boot diskette! Does it boot with higher Fsb than before? If so, have enabled PCI/Agp lock in Bios but also enable one by one alone those Sata controllers. Can happen that that Bios lock affects only one Sata controller (could be same problem like with some NF4 AMD board as I recall) ! This is to check too!
If PC boots by only FD & IDE controller enabled on higher Fsb than before, take some old Ide spare drive formated Fat16/32 & insert it as an only HD enabled inside temporary, but before go here: http://users.volja.net/image/Files/ResQsys.htm & have some fun ... :D :D :D ...
Hasta La Vista, I´ll be back soon ... :)
I know that's a little off topic but had anyone here try the vdimm mod on P4P800 VM ?
THx
well, my experience with pm730 and adapter was very brief.
got my system working and tuned up, when just suddenly, p4c800e died. with smoke.
i hope that adapter didn't die :(
@ spajky: that's what i was afraid of.. only microcodes won't do..
all we need is one interested bios engineer :rolleyes:

A bit different MoBo/Bios design; no hardware checking routines @ post; barebone features w/o added newer peripherrals, who knows what else. The ECS one is so old that even is not supporting 200Fsb & runs even with regular SDRAM ! Since I did not read before whole thread (I am on DialUp!):
What are other non-Asus MoBo (except that mentioned) that work; do you have a list? Make some research for me please!

In your third option, this would involve a set of dipswitches to manipulate vid's(0-5 on and off) and set vcore directly to ic right? This could be done on the ct-479 itself locations u4 or u5, or on the p4c800-e at this location?Quote:

´ALO ´ALO,
Listen to me carefully, because I am gonna tell You only once! ... :D :D :D
@ ALL : Some additional ideas for better final OC : "MODding the Asus CT-479 ADAPTER!" further ... :) [final part]
[datasheet for Dothan & P4 required too]
If you watch your CT-479 from top view having power connector on your left /according to best pics I have not having the adapter myself/ :
- 3 chips on the right are IMO bidirectional cmos digital/analogic voltage clamp Bus switch ICs [Purpose: translating both way i/o Cpu signals to chipset & viceversa by adapting voltage levels; on P_M native boards not needed! Inividual quality of them determines adapters posibility of highest OCs; as an example: generic modded slotkets for Tualies OC-ed them better than PowerLeap slotket having this kind of ICs on-board]
- on left upper corner: IMO all-in-one switching (PWM) regulator/doubler IC [purpose: generating all other supply voltages needed for circuitry on board not using +5 or +12V, negative ones for example etc.] Certain SMD elements around it /caps & resistors/ determine its output voltages.
- big linear voltage regulator on the top of socket (probably using power feed_in +12V line, not sure) [IMO it procures 1,05 VccP voltage for the CPU i/o stages = 2nd core voltage - 1st time after 8y & P233mmx again true CPU differential/double powering!!!] Max current rating 2,5A !
- smaller linear voltage regulator (transistor?) taking previous source (VccP) to generate 0,63V i/o digital signals recognition state reference voltage (GTLREF). It is situated IMO in the left middle between power connector & that PWM chip.
- maybe there around is some other SMD transistor or lin.regulator (can´t find or see it-maybe in the middle between previous mentioned smaller voltage regulator & left upper socket corner!) to procure VccA voltages 1,5 or 1,8V for CPUs internal analog PLL clock generator (4 pins on CPU, see datasheet), but maybe is not even there & previous PWM chip takes care also for that!
- "missing" LowESR cap close upper to power connnector! Designed but not soldered maybe because of space problem with default cooler mounting? :) IMO serves filtering entering power line.
Linear voltage regulators (=LVR) have usually right pin Input, left pin Pilot-V & middle one (connected to its under metal base) is Output-lower/regulated_voltage. Mounted classic SMD transistor usually has terminals: single upper one Collector, right down one Emitter & Base /control/ pin on left. Both types can be positive (I+O or C-npn_Q terminals) on more positive potential) or negative (viceversa) as regulators mainly or even combined /positive regulator and pnp transistor instead & viceversa/.
Positive type "LVR" output voltage is determined/piloted usually by a middle point of a 2-SMD_resistors voltage divider going from its positive O terminal to Gnd (ground, mass, zero volt, black power conn.wire) & usually its minimal voltage is around 0,65V if its P terminal is directly [w/o resistor] tied to the Gnd (no need than for the other resistor!) if the LVR has fixed out voltage.
So to change its output voltage you just need to change those resistors value ratio, maybe by replacing them with other values or changing/diminishing/lowering their value by adding paralell to one of them much (10x?) bigger value resistor to lower a bit their value. If you add additional resistor to one going to Gnd, you will lower that output voltage; if you do that to the other one going to + , you will rise (overvolting!) output voltage. Easy ! :)
For maybe changing that PWM chip voltages (I can´t decipher markings on it), you are on your own by finding apropriate datasheet for it for further procedures if needed!
Before you try anything (sure like always on your own risk not to blame anyone if sh1t happens): do modding stuff on the "Lab Table-non conducting surface" with only adapter involved /no Cpu, no MoBo!/; when measuring voltages & results of mods you will have to power it up by inserting the power connector powered from some PSU on. Should not happen anything, myself I powered many times MoBo´s On w/o CPU or anything inserted in & had no problems later.
Hope I do not have to mention, you have to have some practice with soldering tiny & delicate stuff & have proper soldering equipment with magnifying glass & light, calm hands & digital multimeter (DVM) too. If not (or not having guts), let someone else capable & equiped do it 4 U instead. But if you guys do mods on MoBo, this should not be a problem ... :) But first carefully find & measure default voltages on CT-479 /VccP, VccA & GTLREF ones/ !!! And for checking & doing mods is nice to have a spare adapter (cheap), MoBo (not so cheap) & some older Celeron_M (much cheaper than P_M!) if something goes wrong. :)
What is to accomplish? Overvolting over defaults certain voltages just like Vcore on MoBo! :D for same purposes!
- VccP = Cpu signal i/o stages powering them higher to 1,15V (max.1,2V!-same as "Vcc,BOOT"-default Vcore boot voltage); same effect like upping Vcore, but it has NEVER to be higher than VCcc,BOOT one to prevent reverse currents from Vcore inside the Cpu; files data corruption may occur! [I experieced this with my Tuallie time ago!]
- GTLREF = signal reference point /threshold between signal binary states/ setting it higher to 0,7V; helps chipset having higher margins between 0&1 digital states - better Fsb OC at higher FSB.
Those two task accomplished, Cpu & chipset will be consuming a tiny bit more current & heat a bit more, but only few % ! Shouldn´t be a problem! Max rating: GTLREF 2/3 VccP; max VccP same as Vcore = 1,6V but only if that low 1,2Vcore Vcc,BOOT problem is resolved before somehow, but even with that fixed, I woudn´t go higher for safe than 1,5 V VccP & 1V for GTLREF maybe with additional cooling of those 2 voltage regulators, not to overheat & kill them or damage the MoBo´s chipset or CPU !!!
- 3rd check: VccA voltage for internal Cpu PLL generator: for P4 & P_M is/should be 1,8V, while for Celeron_M can be also 1,5V (or 1,8V) max 1,57 (or 1,89V). Maybe this is selectable somehow by that CT-479 Asus adapter when C_M is inserted (maybe even Bios way) & that could be one of the reasons (lower V option!), why people using it could not OC for example that CM_350J more than max.170-180Fsb/2,3GHz regardless Vcore & cooling !!! (could be that SMD transistor/if there in the middle between mentioned smaller GTLREF voltage regulator & left upper socket corner is responable for this or even that PWM chip, who knows; a need 4 voltage measuring to know that!). Max current rating to Cpu there = 120mA !
- next possible enhancement to the adapter: adding some min.1000µF/16V "missing" LowESR cap there; since can not be mounted normaly because of HSF, would have longer connecting wires (not best), to fix that is a need to add on its contacts under the slotket an additional 100nF block-decoupling capacitor to further "clean" incoming power to the adapter (power stability)!
The effect of this "enhancements" (not counting some more heat generated) is that currents running thru Cpu & adapter/chipset are a bit higher thus lowering signal impedances & so less succeptible to disturbances (signal "ringing") following to beter stability of setup alowing higher OC. But is never good to exagerate with limit values (long term success & running it for years like my Tuallie) !!!
So ... "dr.Spajky" has finished his homework for You all & left the building, now its your turn to proceed ... :D
"...We will Clock it to the Moon, We will OC-it to the Moon to the end of this year, not because is easy, but because is Hard! ... J.OC.K ! :D :D :D
My goal for Christmass: Celeron-M_350J 100% OC on Air, to replace my current Tuallie ... :)
Space (1,3@2,6GHz), the Final Frontier ... :D :D :D
Please snip a bit quoting! when replying ...
k|ngp|n , Yes & No; cheaper & older boards can function like this, but looks like newer ones do not. Bios reads Vid definitions (wire trick! on socket for default Vcore) & after first second checking all voltages recieves from Cpu boot Ok command & gives than digitally thru SMBus data to voltage regulator what "default" Vcore or rised in Cmos settings to set. Thats why that Vcc,BOOT 1,2Vcore problem is present; with my Idea modding digital states directly on the MoBo chip for Vcore might circumvent that problem!Quote:

I've up'ed the voltage using all three methods- using a trimmer attached to the voltage regulation chip, the vid pin mod, and the bios control. I've found no difference between the vcore p4c800 mod and the bios control. Both are great. I think the vid pin mod is a bad idea because you can't finely tune the voltage! For example, I'm running my 730 at 2.9 using 1.478v
Have any1 used dothan 760? Got ne luck with those?... i could get one for cheap(finnish prizes) ~300euros. Just wondering is it worth buying. In theory it could run faster because of the higher 2.0ghz core speed.
IMHO Vid pin mod is a great idea to determine default Vcore (lower/higher just a bit if needed to expand/shrink Bios Vcore setting range) if needed & done properly. In case of my Tuallie & my MoBo bios, I couldn´t go lower than 1,5 & max was at more than 2V. After that mod I could go lower & max Vcore could be set to 1,75V (max safe long term for Tuallies! with better cooling 4 OC-ing) & all values in_between like used to be before.Quote:

Someone should really measure that VccA on CT-479, maybe Asus decided to use lower fixed (1,5V) option on their adapter for that ...
I need to ask a question about cooling and these beast. I have my 730-pm now @2880 PI stable. Now cpu runs -11c idle/2c load. It is still with stock CT-479 adapter in my chilled air chaimber. Now do you guys think that it be wort to put it on chilled WC? I would probably be -20c idle/ -7 load.
I just have seen that most people just gained 100-200 or so Mhz from sub temps with cascades. Ln2 is dif story. I have hit a wall right now @2880 benchable. Without chiled air it was 2.65. I could take cpuz screen @2.960 but that dont make me anything since i'm building 24/7 sys to play games. Wc is installed in chillbox but i realy dont want to oppen her up, playing even @2400 just kicks a**
Yep, looks like 0,09µ process & Dothan core design has a limit @ 3GHz even with Phase cooling!Quote:

My Dothan is benchable at 3106mHz @ -65C
I'm hoping to gain like 3G bench with chilled water. Only 120Mhz to go. Besides on water the temps @load would be realy stable. Same WC holded my Pressy @4.3 @8c load. Thats like atlest 150W of heat. Also with this 730 my temps in the box just stay on same level, much less heat. Onother part is that my PSU rails are also got stable as hell 12v is @ 12.22 @load and it use to drop to 11.67 with pressy.
Anyhow i love this setup. This is a truly overcloker dream cpu. :fact:
On air I'm good @ 2800ish... and yeah, it's a 750.Quote:

The mem timings hurt my PI performance. These are good chips Hynix b5 280mhz stable only @2.8v but wont hold tight timings. Best i could do is 2.4.3.8 @240 mHz. With 3.2v max i could probably go pass 300 but i dobt there will be a need for such with my setup
I will need to sell them now.......
1GB of OCZ EL DDR PC-4000 Gold VX memory with OCZ Booster are on the way ;0]
You think those should do well with my MB? Man i hope they will, I serched OCZ site and it says they are "compatible" With natural cooling they will get in the chillbox i hope i can up the voltage quite a bit :sonic:
Low timings DO matter. I gained about a second in superpi when going from 2,5-3-3-8 to 2-3-2-5 :)Quote:

Getting like 27k with a 6800gt though. My fillrate on the x800 is wwaaaay to low as well - onyl around 7.7k. Only thing I can think of is the 4xAGP but I dunno. Anyone got any ideas?
4x agp does nothing like dropping 7k, but it could very well be a driver related problem.
when i first got my dothan, i slapped on a branspanking new win2k install and did some
benches.. superpi1m, 3dm, the works.. while superpi was about par, 3dm(2k1) was off
by a good few points, 5k iirc. so i asked a few friends, what an intel setup needs to get
the gfx flying (having done my last intel in pentium 90mhz times) ...
chipset drivers was what they told me (doh). in my case it worked wonders - should have
thought about that myself, but got carried away with excitement. swapping a now dead
9800xt with a 6800gt (including new driver install, ...) did show some differences, but
nothing like you experienced..
seeing the gt score as high as she does, i doubt its the agp-driver, but it might be
good checking that one out...covering all bases, so to speak.
btw what dfi board are you using? the pos i855 thing?
Still same Hynix b5 ram @ 2.85v but way better PI times. I managed to do 10x280 1:1 with 2.4.3.8 and 11x 265 1:1 2.4.3.8. When i'l put my chiled water on i should be able to go further with 11x265. I'm trully amazed by this ram cause i never thout it would do 280 @ 2.x.x.x timing. Having mem controler cooled to -25c proabably helps. Will use OCZ booster to give these 3.1v is the max i think they will hold. Is this a good score for my FSB and timing guys? i have not tweaked OS fresh install.

Quite nice scores i think. I just wish i could do that with my upcoming 760. What cooling?.. air? warm water?
Well iam thinking about getting one of these babys but am not sure wether now is the time to get one. I guess that the 750 is the one i want. But is intel going to come out with dual core ones in the near future? Will they be reasonably priced? How much would i 750 normaly go for and where can i get one? What is the best mobo with agp, i guess its a asus with te adapter right? How do these things react to timings on ram? I would love to chill one of these things :D .
That about sums it up thanks alot guys.
This is with chiled air inside the box. It gets beter i broke 2880 wall :banana: this chip hunted me with for 3 days. So far i think this is my max until i hook up WCQuote:

Sup JSU this is edfx from EOCF. Long time no see :toast:
With your phasechange you should look atleast for 750 to get higher multy. The lower the timing the better. Some good bh-5 will do you good. Also look around here how to mount a phasechange to this cpu. They are realy fragile. Get one you won't be disapointed ,these cpu :slapass:

I think in 2006 1st or 2nd quater. There will be single and dual core Yonah. these will have 800fsb instead of current 533. Also they will have more improvements over existing Dothan. I seen a chart where Yonah will be 27w TDP and extra cool version of 17W TDP. Not sure if .65 nm will be used now just emagine how those will overclock :woot:Quote:
Sounds good but what about the new wave of them? when is that comming?
Railer-
I hear Yonah will be on a 166 bus.
Also the Dual core will share 2Meg L2 cache.
Yonah although based upon Dothan, is a major redesign.
Banias > Dothan was not much of a change, so Yonah should be even better :)
Where did you connected the 3,3V on the mem? On a cap or directly on pin 7 ?Quote:
