The ULTIMATE ASUS CT-479 Adapter Modifications...You want MORE...GET IT...

[caater]

I've tried that too.....No go....I raised the internal 3.3Volts to up to 3.7Volts with no impact at all.....

i actually meant cpu io voltage (vccp), it's the same as vcore with p4 but lower with pentium M. also there are several other voltages that need some boost and it seems that you've just done that mister

@ sky

Well these are the one we need. Make sure the 100uf/16v and the tantalum 47uf/16v are electrolytic capacitor. and for the 1uf/63v make sure its ceramic!

* Wtf. the dutch conrad doesnt sell some of the parts :s

tantalum are not electrolytic.

Might want to use aluminum caps like what ATi uses on their video cards (470uf/16v I think they are?) in place of the electrolytic ones if going below -40c is going to be a problem.

[__TRONIK__]

Can anyone come up with an e-tailor in the US where these might be bought? got a few off some dead mobos but cant find all of em. quantity needed would be nice too!


*edit* - just a thought, but could this mod break down the 2.5ghz, 210fsb wall that myself and many others have hit? Going to have to take a chance on another intel 730 otherwise.

[HKPolice]

I think you mean 1uF 6.3v not 63v caps right?? Why would you need 63v caps there....

There was a same question, a few pages before.

No I mean 1uF/63v.....You can use one at over 16Volts though....

If you mean lower left of the front of the adapter, they "where" the jumpers for the 133MHz fsb bus

Corect for all....(exept the 6.3Volts)

www.mouser.com. Not sure which caps are of the right specs there though, huge selection.

[__TRONIK__]

yeah that is the site I found when searching about - hard to find exactly what is needed though

[hipro5]

WTF Happent here?.......I only was out for one day......!.....

HOLY SH**, thats awesome!!!!

this with "ultimate" or only what you've shown so far?

MUST MOD ADAPTER....

Yes this is with the "ultimate" mod.....

Booted up yesterday my THIRD POS 770 CPU.....It booted at 284MHz fsb.....

With an adapter without the mods, the 770 could do undr prommie @ 3117MHz..... , with the moded adapter it reached 3280MHz benchable and 3264MHz Super-Pi 32M.....Not that good.....

[hipro5]

hipro you need to be crwoned "thy god" by all - amazing stuff

reckon you can do anything about the 180 ish limits on the b1's?

I think that Bannias will be helped as well too....

[hipro5]

Uhm, first posting since months now

What about the capacitor at PQ2?
I already started to mod one of my CT-479, but i only found 22uF/20V, try it or better leave it out?

Put it on......Only good will do and no harm....

[hipro5]

Hipro, is see many of the caps rated @ -40. Wont this be a problem when running with ln2?

Is there a problem playing with LN2 without the adaptor, straight the mobo and one - let's say Prescott - .....Same thing.....

[hipro5]

hipro5

excellent work,my friend

A personal matter:i need the IC red circled from the picture.My ct-479 adaptor suffered a short circuit and this IC must be replaced.I cant find it anywhere for sale.
So,by chance,if you have this IC and you are willing to sell it i would really much appreciate it.Thanks man and sorry for this little offtopic.


[IMG][/IMG]

Ha,ha,ha.......That's EXACTLY what I need for two other adapter I was send by friends......I can't find anything about this IC......I have found the other two ones but not this one......

[hipro5]

I Have an adaptor with a broken pin. Are there any usable caps on it?

One more simple request please Could you locate the components here that we're gonna need? Please

Member - XtremeSystems "Team Dothan"

thank you sir

One of my two adapters was with two brocken pins and I repare them....It is easy enough to do so than through it away.....Yes you can use some of the capacitors from this adapter but they are not easily desolder from it....

[hipro5]

I know a shop in Berlin, they should have theese parts. Conrad and Reichelt have most parts, but not the 22uF/10V tantalum capacitor.


1uF 63V or 100nF 63V:
C1, C24, CB1, CB2

22uF 10V:
PQ1, C and E contact. C is the one in the middle, E the one below it.

100uF 16V:
CE2

47uF 16V:

Should be theese contacts, better ask hipro5.

Yes these are the contacts....The small circle is the ground and all the other(not the big circle but the surface) is the +12Volts......You HAVE to clean it first from paint so as to solder on it......

[hipro5]

I cleared out the picture for hipro.



Only have to know witch left leg to witch point? Hipro

No need to replace anything.....Just feel the missing ones.....

[hipro5]

hey hipro,

i compiled a list of parts needed. maybe you should have a look to see if
the part-numbers match with what you had in mind - at times the pics
of the shop that has them shows some 35v voltage samples, whereas the
text describes it as just right.. erm

*** NOTE ***
this list has not yet been verified, so use it at your own risk
***END NOTE ***

the shop is www.conrad.de
up top you'll see a space to enter the article numbers:

1uF / 63V
wima smd2200 1,0uF 1uF / 63V
451008-62, size "2200" - 0,69€ / each

?.....


22uF / 10V
smd elko tantal capacitor 22uF / 10V, 10%
502017-62, size "b" - 0,17€ / each
502029-62, size "c" - 0,45€ / each

Sise "b"


47uF / 16V
smd elko tantal capacitor 47uF / 16V, 10%
502106-62, size "d" - 0,70€ / each
501274-62, size "d" - 1,32€ / each

Size "c" (beter) but size "d" will be OK(biger)


100uF / 16V
mini el capacitor 100UF / 16V -40/105 gr
460699-07, (460699-62??) - 0,18€ / each


if you could check that these ^^^ are correct, we can make it the shopping
list for europeans (if conrad ships to outside germany, haven't checked that
just yet)

About the 1st one could you give me a link?...

[hipro5]

i actually meant cpu io voltage (vccp), it's the same as vcore with p4 but lower with pentium M. also there are several other voltages that need some boost and it seems that you've just done that mister

Vccp is well done on ASUS adapter....BUT you are close enough.....

[hipro5]

I think you mean 1uF 6.3v not 63v caps right?? Why would you need 63v caps there....

NO......We NEED ABOVE 16Volts ceramic capacitors.....You'll not find easy at 16Volts ......The most common is the 63Volts ones.....

[Sidewinder]

About the 1st one could you give me a link?...

It would be in german, if you can read it i could give you a detailed description.
Its a plastic foil capacitor, the foil is a polyethylene terephthalate foil. Higher insulation resistance, lower temperature coefficient than "normal" foil capacitors.
Dielectric:metallized polyester foil
Capacitytolerance: +/- 20%
Temperaturerange: -55°C to 100°C

I hope this can help you.

[hipro5]

U P D A T E ....

OK - OK .......You are a LOT ....

I'll give you one of the mods right now to climb higher......I didn't want to till I bench myself BUT my type is that I CANNOT hide secrets which are for the common good.....

A little summary first....ASUS technicians when they built the adapter, had in mind that it will work with the ULV DOTHANS as well.....ULV Dothans are the ones which wants about 1Volt VCore to work.....There are some pins on the DOTHAN CPU that need 1.5Volts for the ULV DOTHANS and 1.8Volts for the "regular" ones.....ASUS gives ONLY 1.5Volts on the adapter.....These pins(of the Dothan) are for it's internal fsb to work properly - in simple words - ).....They are called "VCCA" pins....By giving 1.5Volts at those pins, Dothan CPUs are "underclocked" as for their fsb and functionality.... ....So giving @ 1.8Volts, we can work with our Dothan as they should.....Min VCCA is 1.75Volts and MAX VCCA is 1.89Volts....I have give ONLY 1.8Volts VCCA for the time been BUT I thing that giving MORE that 1.8Volts - let's say 1.9Volts - it will be better.....Although I haven't tested yet over that 1.8Volts because I have soldered a resistor and not a trimmer so as I play as I wish....
You MUST put the 133MHz fsb jumpers on the adapter......I HAVEN'T tested what does with the 100MHz fsb jumpers.....

GET THIS......





......and LET'S see some real benchies with those DOTHANS out there.....

Can't you find a ceramic SMD one...?.....They are very common......

[Sidewinder]

You added 3.2k at R2 (2k?), what about using a poti and remove the regular R2?
3.2k and 2k parallel would give 2.6k, higher resistance = higher voltage?

Conrad has 100nF/20V, i have a box with 100nF/63V at home.

[celemine1Gig]

For those who are trying to find the parts. Have a look at

http://www.rs-components.com/index.html

They are located all around the world and have nearly all the parts you can think of for any mods.

Hmmmm.........2KOhms is on adapter....... 3.2KOhms is HARD to find though so you can use a 3.3KOhms one and we have > 6.6K (3.3K . 2K) / 5.3K (2K+3.3K) = 1.2453K.....

Don't ripp of the existing resistor...just solder a 3.3KOhms in parallel with it OR a 5KOhms trimmer 25Turns for more accuracy......BE WARE to trimm it at it's MAX resistance and then solder it......

[DaWaN]

If this fixes the 180 FSB limit on Celeron M I am going to buy a Celeron M chip
Nice work Hipro5
