and battery life too probably
true, but you could use speedswitch and keep your speed low when you dont need it. If its stable that is...

I would wait till I can confirm the Vcore mod will work. ALso be aware there are some versions of the Pentium M with only 1Mb cache.

Once I get mine in I will confirm if its a 478 or 479 Pin SSpec code.

Im leaning twoards the 478 because the 1.8 400 was only offered in one pin configuration 478.

Yes the Bainias would be a bad choice. I would not even think of changing the vcore.

Once I can confirm the package I will post a list of the proper steppings.

Seeing as we will be using dothan, I will already go and secure my purchase before someone else uses buy-it-now

ok, i ordered a pentium m 735 dothan @ 1.7ghz for $168. This would put me at 2261mhz if it works

Damn good price. Tommorow I will post a layout of the socket package and the proper pin to ground. Right now I am on Tynelol w/Codine,(Tore a Ligament in my ankle) so im a tad drugged out

I will have to wait on the Vcore mod, as that will most likely require a Permanent mod to the processor. Im not going to post it unless I can confirm it works on my own dime.

rock on! I'll be looking foward to your layout and will make a detailed thread with pictures when I do it.

If I require a vcore increase, which i dont think it will (knocks on wood), I will just sell the 1.7 and try using a 1.6. I saw two 1.5ghz dothans on ebay for about 130 shipped.

Well the one thing is if it requires a slight Vcore increase, It can be scaled back with software. Im thinking of doing the Vmod with a .15 -.2 increase then scaling it back if needed.

If you want to wade through the Data sheet be my guess.

Here is the links(Think this is the right one)

533 Mhz Dothan Specs Sheet.


400 FSB Dothan Spec Sheet

1.612 Vcore would require breaking 2 pins off.
1.644 Requires Only 1.

Even better Idea. Actually I have some conformal coating around here somewhere.

Wait, so if your CPU FSB is already 533MHz, this mod doesn't help you at all right? Or, would this mod let your crank it up to say 800MHz? BTW, does the Dell 9300 have any RAM timings features at all so you can tighten up your timings?

From what I've read and understand, it will only work with the 400 mhz FSB models. Basically you're physically removing (or coating) a pin so that the 400 FSB is instead a 533 FSB with the same Mhz multiplier that it had before. If you got a 1.6 Mhz 533 like me, then it would work great because you could sell your processor and then spend $130 for a 2.0 ghz (or faster) 533 mhz 2MB L2 processor, about 1/8 the price.

I'd really love to hear if this works and if there are any thermal/battery problems.

Sounds sneaky enough. Everybody is selling their 400Mhz FSB on eBay now because they want the new 533MHz FSB so I could probably pull a pretty good deal. However, as I asked in my above post, can you tighten up the RAM timings?

Ziddey has already confirmed this worked on a I6000 with a 1.6 400 Dothan.

Ram timings are going to be controlled by the bios, not sure if they are fixed by dell, or if they are designed to read SPD settings and go from there. Thats another thing to test one of these days.

Thanks. My reason for asking is because all the 1GB DIMMS are CL 3 which sucks. I don't really wannah wait for CL 2.5 so I was wondering if I could tighten if up to 2.5 like you can in most desktops.
