Intel D975XBX "Bad Axe" Mod Thread (including "Conroe" support for rev 303 and lower)

good work fcg

[hicookie]

i'm using stilt's alternative guide,works fine now

[VictorWang]

BTW：
FCG, a separate 220ohm resistor be added to the VR in series to prevent grounding Pin #1 but not in Parallel.

And... a 10k VR maybe better as I had to screw so many circles to higher the vdimm to 2.35v.
but... start from 2.35v to 2.6v , half circle gives 0.1v more. that's dangerous.

you're correct, should say series, not parrallel. I will fix this. Thanks!

Can 24.9 ohm be replaced by 24 or 27 ohm? 24.9 are not so easy to get

[TCounceller]

Tolerance of 1% or greater. 1% of 24.9 is .249... so no :P

Unless, of course, you'd like to throw away perfectly good money.

I said I could supply the parts. Just PM me if you need them.

[hicookie]

some compents are hard to find, finally, my -302 works support conroe, thanks FCG's awesome guide

[infrared]

Hmm, nice job!

I guess there's no chance of modifying a p5wd2 premium w/ i955x chipset

I might skip the conroe and just wait for the woodcrest...

Hi, freecableguy

This Vddr Mod by TAM, not Tarosa, Also TeamJapan

Image 4. Vddr Modification - up to ~2.8V for your DDR2 (optional)

Mny Tnx!!

Thank you for correcting me, I have updated the guide to reflect this.

Can someone give me a link to the 0908 bios for this board. Also is there a windows flash utility for this board?

Thanks

The onboard thermal diode works great to -100c

[Chesterfield]

Really a great job!!

[OMEGA3]

D975XBX Tcore mod, by OMEGA(Team Japan)

Hello, FUGGER-san, FCG-san and all,

Onboard thermal diode works till about -127C,
Hardware monitoring on the BIOS, "00" is displayed when -127C is exceeded,
the alarm rings next, and the frieze.

Monitoring of Two Remote Thermal Diodes by SMSC EMC6D103CZC.
The mod, can be set this temperature to higher.
at 100ohm, for set about +30C

Mod:
Removal 0ohm register, 200ohm potentionmeter set to 0ohm, solder to both lands.
Higher registance to rise display CPUtemp on BIOS.

The alarm will be heard, if it rises it too much at air cooling.

[death metal]

Thanks OMEGA3!

[OMEGA3]

Vcore Mod, by TAM(Team Japan)

Vcore can set BIOS by FCG's mod, This is for need more Vcore.

Vcore Mod: Connect a 50K ohm potentionmeter (set maximum), from Pin #4 of ADP3189 to GND.
Lower resistance to raise volts. Registance at about 6K ohm, rise 0.2V.
Registance to more lower, shutdown by Protection.

Measure point: between the "Green's mark" to GND.

Awesome mods Omega!!
That is the first mod I have ever seen of a temperature monitor That is brilliant!

i had heard of a tcore mod but never looked into what it was.

Great job FCG!!!

I got Rev 304 but there is no need to do Vcore Modification mod obviously since all mentioned OC options (fsb, vcore, 30%, power slope) are available in bios already. And pins are not shorted btw.

[piki]

Hi, I have an intel d955xbk motherboard and all i wan't to know is if there is an easy way to change the vcore on this motherboard like on the 975x. The fsb is easily overclockable over the 10% bios limit with a program like clockgen or systools but i've reached the voltage limit, so any help will be appreciated.

Thank you

I haven't seen/heard anything saying this is possible...but I haven't been "in the game" now for quite awhile, just goin' on what I've been seeing...doesn't look/sound like it'd work.

[ninjagordy]

hi lds, just so any u.k. members know.... the 304 revision is available at www.scan.co.uk . i received mine this week.

justto confirm....do i need the vcore mod for ths revision or not?

Rev.304, I think that Vcore mods is not needed.
If desired more Vcore, then do the extreme Vcore modification(imeage5 of Thread top).
