good call. i forgot to mention that fact. with rmclock you can set the max multiplier it'll use so you could scale down to 2.13 (16x mult) if that's what it takes to get stable. (this is all assuming that you have at least a cpu with 16x multi. also, youd need to be able to boot into windows at max mult, which in your case would be 18x133=2400)

Can you change the max multiplier in RMClock somehow? Using the default install, it's capped at 15x. I have a Pentium M 2.0ghz.

You cant adjust the multiplier higher than it left the factory.

Yeah, I figured that out after I posted. So to do the mod this thread is mostly about the top upgrade would be the 400 mhz fsb 2.1ghz pentium m. I may try it later on a 2.0 or a 2.1 after the 2.26 comes out and the price drops a bit.

Gonna have a very hard time getting a 2.1 stable at 2.79. You are gonna also have major heat problems. I think this mod could work with a 1.8 no higher. I dont think the coolign system can handle any more than that really.

They had unlocked multiplier pentium m's on eBay a few days ago, all priced at 150 bucks a shot; too bad they all sold, and were all engineering samples. Still would have been awesome to experiment with, esp. since those kinds of chips are so rare.

I think CPUs with unlocked multipliers are only useful for a motherboard that lets you set the multiplier in the bios... right?

All Pentium-M's have unlocked downward multipliers. Akin to the Non-FX A64 Chips.

Now Id Imagine even ES Chips would have to have a upper multiplier set at the factory. If not the bios would not know how to correctly set the ES chip up upon POST.

Well it'll be fun to fry, I mean try.

The chips were quoted to be model 745 (which is 1.8 ghz) and said specifically in the description that they were multiplier unlocked upward. I would love to have owned one, if not for the fact that now they're gone

Not necessarily. RMClock allows you to change the multiplier, which is one of the tools I will be using primarily.

So.... so far there are two people that got this to work and one that semi works, not prime95 stable... ?

I'm eyeing this. I'm thinking about trying the 715 to 533fsb. I currently have a 1.6ghz 533fsb on my 9300.

If I find enough people getting good luck with this, then I'll try the 715. 715s are about $220 new. Not that bad of a price considering this mod will make it equivalent to a $400 cpu.

Anymore updates on this? Is everything still working well to the few that tried? Any odd problems you have run into?

As a side note--why not bring this topic into the general forum as a new thread----i.e. ziddey--to get more people interested in this and attempting it, that wait to get more success in a variety of notebooks and work out any kinks. I bet there are a fair amount of people willing to try this, but few know about it as this is in a Dell 9300/XPS 2 specific forum.

Just a thought....

I have a 9300 with the 1.6. I just ordered a 1.6, 400FSB, 2MB cache chip and hope to run it at 2.13. I think this should work. I would prefer not to be doing volt mods. If it doesn't work, I can always downclock it to 2. I just paid $144 on a buy it now on eBay (shipped.) I will let everyone know how it goes. I hope I will have it in a week or so. I am also going to try to document with pictures. Also want to add Arcitc Silver to the CPU and GPU at the same time.

That way both companies can do minimal work and still throttle the market. That's the problem with having only two companies, they can easily control the market. I guess they never thought there would be anybody smart enough to uncover their secrets. Pretty tight shyt for those of us that can read, though.
They have been doing this for years. Once CPU's get relatively stable, and yields go up, chip manufacturers may be making all chips that could be say "2.2 ghz" but then they can't extract as much money from the market as possible. If you sell them at different price levels, you can discriminate and let people pay more for the same product (minus the clock lock they put on after). Plus 99.9% of notebook users won't do this so I don't think Intel cares too much :0)

Other than heat, what makes a processor unstable? Why does raising the voltage help? If it's only heat that causes problems, what is the limit? Just some questions I've never heard the answer to.

heat and resistance are directly related i believe. thus, with higher temperatures, the electric signal can't transfer as well and the error in transmission occurs.. voltage dips. (that's why they send high voltage down power lines, but you have a transformer to drop the voltage down. the voltage loss due to say the "internal resistance" in the wire will be the same for the same amount of current, thus having a higher voltage will take a smaller hit in such cases where the error occurs. however, with higher voltage is even higher temperatures. and it continues

Hi, I am still running strong on my 2.26Ghz CPU in my 9300. I believe I am still the fastest 9300/XPS2 system in the world, eh?

The other day, I compressed 3 DVDs into xvid back to back. It took about 24 hours (my 9100 2.8ghz takes about 30 hours). During this process, the temp ranged from 58C to 67C. No issues though. Woohoo.

What the hell are you using to encode DVD's to Xvid. 8Hrs each is a lot.

I use AVISynth to virtualdub. I set everything to max and turn all options on. Most people dont even know where the extras like GMC, QPel, and Adaptive Quants are located (but they add 2-3 hours) easy.

What chip did you buy? The 1.7 or the 1.6?
