Overclocking Thread of Celeron D (Cedar Mill) on P45 Chipset or any Unfriendly Mobo

Hi, everyone.

I start this thread for 'wytiwx', and his turn now. :D

THX Ivanqu. :D

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:

OK, all mods done, let's rock. :D

This old skool overclocking just does it for me. Good job, now get that chip COLD! :D

Extreme cooling was already done before this thread :D

P45 8GHz done. Real valid Vcore was 1.93V.

Now working on Gigabyte EP45-DS4, ASUS P5Q Pro and DFI LT X48-T2R.

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

Please please please get an Asus Commando vmodded for the chip, or a P5B-Dlx :D

I can try to bin this 347 chip on P5B-DLX when I get free time :cool:

But I'm not good at ASUS P965 chipset, and sometimes I will hit damn Cold Bug Boot.

Gigabyte EP45-DS4 finally done, need one more pinmod: BOOTSELECT (Y1).

But I can't save any BIOS setting, so I have to load default setting. That's a little hard work.

Mod way: FSB 800 mod & VID mod
Mobo: Gigabyte EP45-DS4 Rev 1.0
Cooling: air
BIOS Version: F10b
Vcore: 1.235V

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?

I think it's too hard to do this mod on DFI X38/X48/P45, shoud I go on?

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 :(
