Cedar Mill is old, but still have something interesting to do.
I tried some mobo s which are unfriendly to Celeron D (Cedar Mill). 'unfriendly' means you can't post or overclock Celeron D on those mobo s without any mod.
Now I post some works, and I appreciate more info and help. :)
First come is P45 chipset. How to run Cedar Mill on P45?
P45 do 800Mhz FSB at least, Cedar Mill do 533MHz FSB by default.
So the first thing is FSB 533 to 800 pinmod.

For pins insulating/isolating, can use double-sided tape or insulating adhesive.
For pins shorting, can use aluminum foil or conductive adhesive.
Remember: do not short pins directly, insulate/isolate pins first.
BSEL1 connected to VCC is OK, but not necessary. You also can isolate BSEL1 on some P45 mobo.
BSEL0 can connect to VSS (H28), but inconvenient and risk.
Why I connect BSEL0 to E28 not E29?
In Celeron D datasheet, E29 connect to VSS, but on P45 mobo, E29 not connect to VSS always.

This is my FSB 533 to 800 pinmod CPU_Celeron D 347 (D0 stepping)

The second thing is VID mod.
Many P45 mobo s are designed with VRD11.1 PWM and power phase, so VID mod should do.
How to know VID of a Celeron D? I use Gigabyte EP35 mobo, it can tell me VID.
My Celeron D 347 VID is 1.2625V (VRD10.1), so I did VID mod like this:

Maybe the mobo's BIOS stop me, mobo post with C1 error (Award BIOS).
Need help :(
Is it wrong that this excites me more than a 7 GHz Ivy Bridge? :D
I don't think so :D Celly D powah! ermm..mebbe install on diff chip 1st :shocked:Quote:

Celeron D worked fine on many ASUS X38, X48 mobo s but Rampage Extreme, here was the thread: http://www.xtremesystems.org/forums/...ead.php?244033
Since Rampage Extreme can bin Pentium 4, so it's not so hard to bin Celeron D.
By FSB 800 pinmod, Rampage Extreme can say 'Hi' to Celly :welcome:

good thread, thanks!
First I see hipro5 on HWBot. Then I see this on XS. Sometimes the past strikes back. Thank you for the post!
It's pretty interesting that:
1) BSEL mod works (Asus started blocking it on 945P boards)
2) BSEL mod is enough (like Rampage Extreme)
Could you share those MoBo datasheets you've inserted info from? ;)
C1 on Award means memory problems. Maybe it's the strap+mem ratio problem. As for DFI X38/X48 LT they work only with Core CPUs. My X38 LT T2R doesn't boot even with Pentium D. But DFI P35-T2R works fine. Sounds like racism :D
I can help you check more ideas as I'm fond of modding hw too.
P.S. I think X-mods is a more proper section for this thread: http://www.xtremesystems.org/forums/...83-Xtreme-Mods
THX, man, you're right. :D Please tell me how to move this thread to X-mods?Quote:

The mobo's datasheet I inserted only have EP45-DS4 Rev 1.0, sad... :shrug:
Very interesting thread as usual from you...you're the Celeron man xD
Do you guys have any idea on how to get a prescott to run on a tpower i45, as the board does not support it :(
Ask the moderators via PM ;)Quote:

Keny,
Where does POST stop?Quote:

I will get back to you with the post code when I get the board back out and running up. Probably a day or two before I get time toes with it.Quote:

If you want prescott on Biostar I45, I think VID mod first.Quote:

Is the VID mod on prescott the same as the VID mod on the celeron D, like below?Quote:

before VID mod, you get to know your prescott VID (VRD 10 or 9).Quote:

I can run the Prescott on a old 775 board and get the vcore from CPUz if that's any easier, or does it need to be measured from them pins, I presume I just measure each pin to GND
Edit: I don't have a P35
I'll move it to the Mods section if you want.Quote:

Vcore from CPU-Z is not so accurate, for example VID 1.2500V and 1.2625V can be showed as the same 1.235V.Quote:

Yes, my friend. Thanks for helping :)Quote:

As your test result, VID [7:0] should be 01110011, Vcore in VRD 10.1 should be 1.3750V, but in VRD 11 this VID code is weird.Quote:

On the old board (some generic msi thing) this pentium 4 540 and the stock vcore is 1.22, it goes up to 1.3* under load, damn p.o.s board fluctuates all over constantly but it settles @ 1.22 on idle
Just to confirm, as per the pin# in the diagram i'm getting 11001110 on the i45
http://i247.photobucket.com/albums/g...ps8eb75159.jpg
Do you think the same vid mod that you done on the cele will work on this p4?
P4 540's VID works with VRD 10.1, the same as Celeron D, so I think it should work if VID code is correct.Quote:

Why did I do FSB mod? Because CPU failed to get 800 FSB on air without mod.
Why did I do mobo Vcore mod? Because Vcore 1.90V limit (including Vdroop) without mod.

Nice results there.
Is there a mod to get the CPU multiplier unlocked as I have got no adjustments at all on my CPU ratio after doing the vid pin mod on the p4 540, it overclocks ok but its limiting as the CPU ratio can't be lowered once the clock reaches a too high speed for the ram devider to cope with
As you can see its greyed out with some sort of error message

By my testing, Gigabyte P965/P35 mobo can change P4 CPU ratio, ASUS P965/P35/P45/X48 can't do that.
Ok thanks, no biggie, its just nice to be able to adjust it for spi runs etc, where ram efficiency is key. Glad I don't need a different board to run these old cpu's as I only have this one 775 board that's any good at overclocking.
Another way for FSB 800 mod.

Maybe you guys are bored at Celeron D 347, so I tried a 360.
Celeron 360 has 26x multiple, will did 5.20GHz at boot by FSB 800 mod, a bit hard for air cooling.
But I still did this :)
