Overclocking the Pentium-M - Page 3

Too close to turn back now

Can not host for long, so someone else please grab the above file if desired.

Numbers on chip:

EDITED 20 minutes later.
Just updating on the ease of disassembly on the i9200.
Took me less than 20 minutes to put back together.
This is by far the easiest laptop I have disassembled.
I think Dell was pretty smart in the design, that allows cheap labor to easily replace customer parts while on their break from flipping burgers. I think I did see part of a fry inside.

This is sh...
it is the ICS950810...
this chip has no smbus-functionality... no chance to overclock.
the only possibility is to replace this pll with one pll with smbus-functionality.
for this you need verrrry goood soldering skills

O.K., if you were to choose a correct replacement PLL, you would choose the one best for overclocking (if it makes a difference), most compatable with the i9200, readily available, and low cost. There are dozens listed, and of course most will not work.

With the above in mind, what is best choice, and possible venders (USA)?

Thanks for the help!

Somebody crack open their 700m!!!

What are the chances of Dell limiting the OC'ing ability in the 700m in a similar manner to the 9200?

It is a CK-408 clock. Thus you have to look for this kind of clock. A good overclockable Ck-408 is the ICS950813. But care. You have to change the pin FS1 and FS0...
In your application there is a 100MHz FSB. Therefore FS1 (Pin 55) should be low and FS0 (pin 54) should be high. To get the same conditions with the ICS950813 FS1 (Pin 55) and FS2 (Pin 54) MUST be low...
This means: replace the ICS950810 with the ICS950813 with following change. Do not connect Pin 54 with the soldering pad but short it with Pin 55 to get a "two times low"...
remove the old pll by destroying it:: cut of the feet of the old pll with a knife and solder out... Then take the new Pll and solder it with a microscope, if possible. otherwise you do not see, what you are soldering...:-)
Then download cpufsb from www.podien.de. now you are possible to overclock your cpu in little MHz-steps...

O.K. I see how this chip should work.
But can not locate it anywhere.
Usual suppliers like Digi-Key or Newark do not list this.
Google was no help as well.
I understand there may be a minimum quantity.
Any source in US, or shipped to US?

Is there any other electronic devices that may have this chip that we could scavage?

BTW, I'll have a friend of mine do the soldering, as he has done a couple dozen TSOP's for me, which are similar. Uses a soldering torch though (leaves solder on pads), and he needed to know what was on the opposite side of the circuit board, (so nothing falls off). Most of his work can not be distinguished from factory soldered chips. This also helps should the need arise that original IC needs to be re-installed for warranty purposes chances.

Thanks for your help.

I have a 1.6ghz dothan coming and that I will stick in my d600. Any chance that I can overclock my d600?

Still looking for PLL ICS 950813.
No luck anywhere.
Please, someone, somewhere, provide a link to this or a compatable PLL chip, so all the Dell P-M owners can finally overclock their systems!!!

I will gladly be the first test dummy. Just point me to where I can purchase the ICS950813.

Could it be this simple?

Assuming that a 1.8GHz (100x18) can run 133x18.

Look at the data sheet for the PLL used in the i9200:
http://www.icst.com/datasheets/ics950810.pdf

Pins 54 and 55 determine CPU FSB speed.
Currently set at 54 = is High, and 55 = Low (ground), which equals 100MHz.
If it is set at 54 = High and 55 = High, then it would be set at 133MHz CPU.
So, if we lifted IC leg 55 off ground, then jumpered it to pin leg 54..............

This would also keep PCI bus correct at 33Mhz.

That easy to make the 1.8GHz into 2.4GHz?

I tried using this guide:

http://www.rojakpot.com/default.aspx...ar1=177&var2=0

First time I tried the two clockgen versions neither detected the correct clock speeds on my 8600. Yet, strangely today, CY28346 detected it correctly at a CPU speed of 1698.58.

I'm new to overclocking, so shouldn't really be meddling with this sort of thing. But I tried overclocking to 1.8ghz which wasn't too high and my laptop didn't blow up.

Though when I reset my PC it reverted back to the original CPU speed.

This probably doesn't help anyone though, but I doubt I'll be meddling with overclocking until someone else puts up a tried and tested guide being a n00b and all. Rebooting the laptop and praying I didn't break it isn't a fun thing to do!

EDIT - On further reading I'd need to set clockgen to startup with windows in "ghost" mode it would seem. Does this mean progress?

EDIT - On further research; when I overclock it seems to mess up my audio drivers. I get no sound, WMP says there's a problem with my audio drivers as well.

EDIT - gah another edit. I tried overclocking whilst playing music in WMP, I can overclock to 1.8ghz no problems, when I try 1.9ghz the audio starts popping and crackling, and stuttering. Not sure what that means, hopefully someone else knows.

EDIT - No wait, my audio drivers have gone screwy even at 1.8ghz now. Confusing to say the least. Enough messing around for today though.

Anyone help me out?

Is it abnormal that I'm able to use clockgen on my Inspiron 8600 Dothan Pentium-M 1.7?

Why is it screwing up my audio drivers. I'm actually quite intrigued. Though I've also noticed when I've overclocked my laptop hangs on the XP shutting down screen when rebooting.

Your lucky you can actually overclock the CPU... I can't

LMAO!!!

ALL 8600 USERS!!! LISTEN UP!!!!

I just realized I used the wrong clocking tool.. LMAO!!!

The correct one is in the Intel CY28346!!!! and I tested it, and it works

Edit - Odd.. If i hit 1.8 ghz, the sound cracks.. odd.. I can stay at 1.76 ghz and nothing happens except being faster...

Yeah I mentioned the correct clockgen in my initial post. In fact, you just mirrored everything I said.

Good to see I'm not the only one getting the crackling though.

I hit 2.4.. lmao... but the sound card just reported "unable to activate" so yeah.. no fair, I want 2.4 on my 1.6.. lol..

Oh well, I'm happy with my 1.77 Ghz But it seriously kills the battery life at max power...

I'm nuts

Just to let ppl know I'm nuts about OCing

I tried using the CG-CY28346 clockgen on my 8600 and it didn't work. I have a 1.5 gHz 2mb cache Dothan. (Yes I'm sure it's a dothan. CPU-ID says its a dothan and it shows 2 mb cache.) Anyways, it'll correctly show the clockspeeds, fsb, etc when I choose get values but when I try to change the FSB, everything but the memory speeds will just go to "-1 .#J" Anyone have any ideas? I'd love to get a little more power out of this thing.

Yeah, same thing happened to me also!! Anyone found out the solution for this problem?

I know this doesnt go here, but I dont know what kind of problems could bring to OC the cpu, I noticed when I have my video card OC the Powerplay doesn't work properly when going battery or pluged, it show me a lot of errors, and I really want to keep powerplay hehe.

no problems.. if i slow it down it goes to 600 mhz.. no biggie. Battery life at max sucks.. before i had 5 hours minimum but with full power i only had 3 hours.

Temp doesn't rise, still normal. That was my big issue is the temp but temp remained normal and stable
