770X CPU Upgrade to PIII Help?

[arkan]

[Moderator edit: Moved from Official 770 Upgrade thread]

Hi,

I have a 770X with DEVA card and Toshiba DVD rom, and I want to upgrade it to P III with your explanations.

My 770X has 13.4 LCD with 1280X1024 res. and 8MB Video ram. 40 GB HDD, 196 MB RAM

I have just upgraded its bios without battery successfully.

Now it needs to be upgraded to P III.

I believe that all informations on this forum is full of knowledge to upgrade its CPU to P III.

Thanks

Sounds great. If you are looking for help with the upgrade, then I would recommend starting by reading The official 770 Upgrade and general information Topic. Then you can post specific questions here in this thread.

Thank you for your quick reply Phil,

Yes I already checked all topics related CPU upgrade.

But I'd like to ask you if it is possible to use PIII CPU of Toshiba laptop ( satellite 2670 DVD) in TP 770X, and if I use a speed step CPU ( For ex. PIII 850 MHz ), is there any hardware modifications for max speed ( to cancel speed step function)?
( I read some modifications of speed step CPU for TP600 )

Thanks

The processor that you will need is a MMC-2 PIII, and for the speedstep mode read this.

Thak you for your reply cmarti,

I had already read this link, but there is only TP 600 CPU speed step modification in this link.

I wonder if it is available for TP 770X too.

[...] there is only TP 600 CPU speed step modification in this link. [...] I wonder if it is available for TP 770X too.

The CPU is the same in both machines, and theoretically, the mod should have identical effects. I'm not quite sure if someone in this Forum is running a modded speed-step MMC-2 CPU in their 770X or not, but I'm pretty sure I've noticed someone running a 770Z with such a mod (+ the DeepSleep utility) and achieving max CPU speed by doing so.

Of course, there are no guarantees that you will be successful with your specific machine: you have to be pretty good with a soldering iron to do this correctly and there are several other potential roadblocks you can run into simply doing a standard CPU replacement on a 770X machine.

Thanks Phil,

I will check it with TP 770X soon.

Actually I'm an electronics engineer and can do such modifications easily.
