Cheap Processor Upgrade? - Page 3

Timings on DDRII modules suck in general.
However that aside, this mod has some huge potential.
Ziddey and I are working on it.
Ziddey is going to do a guide for the I6000.
I am going to design a guide for the I9300, and also a Vcore mod guide.

Actually they are cas 4 @533 (cas 3 @ 400)

Sweet. I love you Spaz and Ziddey.

It still seems too easy though. What exactly are the downsides to this? Just a hotter processor and a little less battery life?

Warranty becomes void, could mess up your laptop if you dont know what you're doing, and pin moddiing can suck if you dont have a steady hand.

Ziddey gets the credit for the Idea. Im just going to add onto it with the Vcore mod.

I dont imagine heat output will go up much at all, unless VCore is altered. Probally slightly less battery life, but the boost in performance will offset it.

I doubt heat will be much of a problem if you dont raise the vcore. My desktop 2.4 p4 runs 3*c hotter under load @ 3.5ghz

I guess I don't know as much about processors than I thought I did. If such high performance can be achieved without much problem (coating one pin with nail polish) and very little extra heat, why isn't Intel selling 2.0 Ghz Pentium M's for what Pentium 715's sell for now? Is it just one of those things where it's the only way they can make money? But why not just release faster and cheaper processors and blow away the competition (Turion) and do the same for their higher end models, so they basically move their entire processor line up by 500 mhz for the exact same price.

No Gold Beater Im sorry this will only work with the i915 Mobile chipset that supports both 400/533 bus speeds. It will not work on a 855 chipset laptop, because that chipset doesnt support 533 FSB processors.

I am going to be ordering my 1.7 Dothan off ebay today or tommorow, My laptop is going to be here monday, and I should have a guide up by the end of next week hopefully.. Unless someone wants to overnight me a spare 1.7 :P

i think that some 855 chipsets can do 533, but they sense the bclk pins instead of the bsel i believe. i'm not sure how exactly those pins work. the tech sheets dont document those much





also, could someone with a real pm 760 (2.0) chime in with what their default vcore is? because if it's the same as that of the pm 715 (1.5), there's no reason at all why an overclocked 715 would be any different at all from a 760. and if dell uses the same heatsink, then it should function in that respect identically as well.

and if the vcore on the 760 is higher than that of the 715, then more power to you! you have a cooler running 760 and itll have longer batt life than a true 760, and it should be stable still. intel puts a lot of buffer into these.

Ziddey - Could you show me a link to the pinout. I have the I6000 with the 1.5 and would like to try this mod on it. It seems like the process should be the same as my 1.6 p4 to 2.4 mod. Drop a u shaped fine copper wire connecting 2 holes in the socket right?

exactly. drop a u in there and youre good to go.

http://www.intel.com/design/mobile/datashts/305262.htm

there's a link to the download page. the pinout will be top down view, which is basically socket view.
edit: the bsel0 is row3, #16 (26 columns total)
to the left of it is a ground (vss) and to the top is one too.

Thanks. Well I'm off to get some prime 95 heat output in stock config. Rip my new computer apart and run prime again to see the difference.

My wife thinks I'm crazy. You should have seen her face when I bought a new truck, brought it home and proceded to rip the thing apart to install a new set of camshafts.
