Excellent work and links

Should be sticky along with parallel thread

Thanks for the time, make it look SO EASY

You need to explain this mod a bit clearer IMO. The thread header mentions both I9300 & XPS2. (both are 533fsb PCs) So what I think your doing is replacing the stock 533Mhz CPU with a new 400Mhz CPU, and then applying the Pin mod (wire) your tricking it to run at 533Mhz for a nice little overclock?

If this is not what your doing, then clarify.....


What we need is a mod to make our stock CPU run at say 566Mhz or so...

If it hasn't been pointed out yet, when cleaning the thermal adhesive off the GPU/CPU, its best to use isopropyl alcohol. It will clean the surfaces really well which will ensure smooth application of AS5 and proper contact of the HSF with the CPU/GPU.

I meant to say that also. And the surface of any cooler should be as flat and smooth as possible, no scratches. I hand lap my desktop coolers with up to 2000 grit wet paper for a mirror finish. In the perfect world we'd have perfect metal to metal contact, no paste needed. But in this world we have pits and valleys, etc. But the smoother the finish, the better the metal to metal and less paste is needed so it works better!

OKay forgive the nOOb'ish question, but I am waiting for this Laptop to arrive (although I only got the 2.0 processor not the 2,13). What is it that this mod accomplishes? From the way you folks are talking it is something VERY obvious to most people in this forum, but maybe you guys can explain it in a way that makes it clear to me what this Mod is giving you in terms of addition to your processing speed, or whatever?

Thanks and sorry for the nOOb question.

I have edited the post to include the alcohol suggestion. The coolers DEFINITELY needed to be lapped, but i didn't want to get into that. i will edit it to state they should be lapped and look elsewhere. I will try to add a more concise definition of what this does in the first paragraph, I think it is readily apparent.

This mod accomplishes taking a cheap, low speed 400 fsb CPU and turning it into a cheap, 533 fsb CPU. If you already have a 2, it probably isn't worth your while, unless the 1.8's are found to work fine at 2.4. If that is the case, then you should sell your 2.0 and but a 1.8 and make some money on the swap and have a faster CPU

ohhh boy I just embarassed myself, lol

I wonder if it would be possible to replace the aluminum heat sink for the 6800go in the 9300 with a copper heat sink, that would also help the heat and allow for higher overclocks for more bragging rights

We need some more people to try the mod with the 1.8 for a 2.4oc and I'd like to see some benchies(stress testing too) comparing the stock 2.0/533 to the newly modded 2.4Ghz cpu. Who's up for it?
I've spent too much already on my desktop San Diego/DFI upgrade to experiment myself.

I would really like to see some more info on the 1.8 mods too. What do we have, 2 confirmed so far? I don't think I would upgrade mine again. Unless of course, someone wanted to take my 1.6 off my hands But it runs nice at 2.13, so I am not complaining.

Come one stcky the threads mods!!!

wow howd you take such good closeups

i had so much trouble getting nonblurry closeups with my canon a75

thats why my guide doesnt have any actual pics

great job!

Thanks. I use the macro zoom on my old Nikon CoolPix 2.1 megapixel. I got smart at the end and turned off the flash. If I had done it sooner, they would have looked better. But i wasn't about to take it back apart and redo them

I felt our guides were a good complement to each other. Yours has a lot of the good background/tech info and mine has the step by step.

my 1.6 ghz comes in tonight, was $140 off ebay including shipping hopefully I can get $100+ for my 533 fsb variant to make it a really affordable upgrade.......on a side note it seems like 800fsb should be a possibility because the 915 chipset can definitely handle it with the p4's, this would make a 533 fsb 1.6 ghz a 2.4 ghz 800 fsb chip

I just looked at the tech docs for the p4 socket 478, and the bsel1 and bsel0 settings don't correlate to the same speed:


bsel1 bsel0 p4 pM
L L reserved 133
L H 133 100
H L 200 reserved
H H reserved reserved

I guess this probably means the bios would have to be heavily modded....oh welll it was a thought
