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

[Dr.Spankenstein]

Hi all,

Let me preface this by saying this was my first build, but I'm a quick study and have no preconceived notions...

With that out of the way, I'll let you know what I'm workin' with (read sig.).
I have tried to perform the OC DEBUG mod with a piece of solder wire and some tape. I am not quite sure if it was successful due to the fact that one of the first things I did once the OS was installed was to update to the most currect BIOS. (After reading the recent poor reports, I realize that this was part of my problem.)

What I'm mainly trying to achieve is access to the "Advanced"/"Performance" menus in the BIOS. With the 1478, I was able to select up to 50% burn-in (only stable @ 30%) but I have no provision to adjust VCore. Would anyone have suggestions as to how I might access this? or more specifically, is my mod no good or is the BIOS version the real issue? I did try to revert to the 1304, but it was completely different from the 1478 (menu wise).
For instance, on the "Main" page of the 1304, there was a heading where the multi-processor enable/disable line would be in the newer Bios that read "single core SW" or something to that effect. When in the "Advanced" menu, selecting "Override Settings" took me to the warnings, but provided no options.

As it stands, I'm using the 30% burn-in with a little bump to MCH and FSB voltages. Running my RAM @ 1:1 533=693Mhz eff.)
I would like to enable Vdroop and adjust the core voltages by what ever means possible. Any help would be appreciated.


p.s. Sorry for the dump!

Hi,
I think that your mod wasn't successful, otherwise you was able to see VID option to set vcore, even if it doesn't work with last BIOSes (147x)

No response from Intel yet about the problem of the vcore with last BIOSes

You were right about the mod not being successful, so I went and purchased a CircuitWriter pen. Now we are talkin'! I also flashed back to 1763 BIOS and things seem much more stable. That would agree your findings about CPU VID settings not sticking with the newer BIOSes. (Way to hobble myself right out of the gate! )

Well, at least I can ratchet back my voltage settings to default and start from scratch. I almost piddled myself when I got my first 3DMark05 score over 14000! Me likey the "F" chip+X1950XT goodness!

Thanks for the suggestions and I look forward to hearing what Intel has to say to you.

Cheers,

Hi guys
I'm here again but unfortunately with bad news
I've contacted Intel by telephone too and I've spoken with the technicians at London... this was their response (by mail):

Intel response:
Dear Mr. INFECTED,
Thank you for contacting Intel® Customer Support.
We are pleased to assist you within the scope of Intel® limited warranty.
Case regarding changinging Voltage ID for the Intel(R) Dekstop Board D975XBX.
I would like to inform that it is not possible anymore to change the Voltage ID in the BIOS of D975XBX. you are right that with older BIOS versions this option was available and was functioning. This option by default is set to default and changing it will not work as expected. This is not an issue but a function we have decided to not implement anymore in the current BIOS versions.
If you need further information then please call us or reply to this email
Kind Regards,

They say that this is for stability reasons with Windows Vista but I think that's not absolutely true! I think they wanna induce to the purchase of Intel Bad Axe 2 D975XBX2, because this remains an exclusive option of this motherboard
Unfortunately with old BIOSes there's not a full support to Windows Vista (I got an error while I tried to install it), so we can't update BIOS from the v1463 anymore if we wanna continue to change CPU VID and do overclocking!
In my own little way I'll continue to send technical email to Intel, about the same problem, hoping that they restore CPU VID... but I need of your help too, do contact Intel you too, maybe together we can change something!

Cheers,
