Pin mod on a clarksdale mobile CPU

I am unsure how to start research on this but I was hopeing that some one here could help me find a Pin sheet to try and proceed

Please share what you find

VID table page 85.
Pinout page 106.

You can clearly see how to volt mod.

What is your aim, volt mod or OC?

 

i720 ................

 

Maybe look for it here:
http://www.intel.com/products/processor/index.htm

 

only way i know of is to do the same you would do with FSB with a pin mod on the montevina platform.

I am quite inexperienced in this matter but i wouldn't mind some help in testing

 

So you're looking at this datasheet (for others who might want it):
http://download.intel.com/design/processor/datashts/320765.pdf

Look at page 72, I don't think you will be able to generate your own clock.

You could be better off looking for your clock generator on the motherboard and pin mod it to 166mhz or 200mhz.

EDIT: Sorry I didn't see your last post. Any chance you would take apart your notebook to find the PLL?
Maybe somebody should try it on a less expensive desktop first?

 

I'll take apart my laptop in a heart beat it's easy for me now

The blck is unlocked because it overclocks the 920 using it in bios

 

Next time you have it open, could you please take a few pics of the motherboard or maybe take note of what PLL it has (if you can spot it).

The notebook must have a PLL, and it's likely the PLL is programmable. So there is a chance you could overclock with software. Though since abo no longer supports setfsb, you would have to do it in linux (see grub2 bootloader OC: http://forum.notebookreview.com/showthread.php?t=430230&page=3).

 

i will find it tommorrow.

ITs a PM 55

 

I can actually change my voltage in the BIOS

ALSO i just found out the Bclk is in the BIOS. 920xm can get a 5% overclock and when it is enable the Bclk adjust to 140 mhz instead of the standard 133

My M17x will be opened tommorw during school. I have the R-2. Hopefully i will be able to get this working. I am excited because:

I know the BLCK is unlocked
I know it works on the 920

 

Any chance you have a phoenix trustedcore BIOS?

 

not 100% sure if i do or not. I do know its phoenix, I have PBE and as soon as i can fgure out how to dump my bios i will go through it

rewrite that BLCK value

They have not posted it to the Dell website yet

ALSO

I whipped out setFSB and i can ALMOST get all my stats and ONLY the first 5 work to even get some stats.

SO i am guessing i have a ICS which is the most common

 

Click on the diagnosis tab and select "PLL diagnosis" as the PLL, click getfsb and post a screenshot. I will be able to tell you if it's ICS or not

 

less chips i have to sift through the better

 

Something is wrong. It didn't read the registers.
Could you select the PLL you did before (ICS9248BF-102), click getfsb and upload the screenshot again, but with the diagnosis tab showing.

 

its the same. It will not read them since technically there is no FSB ni guess... Its alll handled on the CPU

 

I would say it's because setfsb doesn't support the chipset so it can't access the SMbus properly. Same thing happens on older notebooks.

Looks like your best bet is a bios mod or a PLL pin mod (if you can find it and if it's a good one, i.e. not some realtek PLL).

 

Sigh**

Wish the setFSB guy was around and yea

I bet i he would of charged money he would still be doing it

I am still going to crack it open tommorw to have the pll to try and help with th grub project

 

Ok, good luck

A photo of the PLL and the area close to it would be great (to see if resistors are directly connected to any pins, makes it easy to pin mod).

There is a guy on this forum (inteks), he is writing code for a new setfsb in C#. Looks like he is getting close.
I can give you a link to the source code if you want to check it out.

 

C is NOT my code

but i would love to help test

 

Link to the project:
http://code.google.com/p/setfsb/source/checkout

You need to use subversion (I don't know anything about it), you can use http://tortoisesvn.tigris.org/ to check the code out.

Problem right now is that it can't enable the SMbus.

I'm not good at programming at all. I took a look at the code using visual studio, I can't help though.

Great work, too bad I can't find the datasheet on the IDT website.
Maybe it's too new?

 

I looked as well

Wish I had a program to test it
