Pentium M 735 1.7GHz Processor upgrade?

I think I've found a processor to upgrade to. But would firstly like someone to confirm to me that it will work, plus my bios will run it.

It's to go in a HP Compaq nc4010.

I cunnrent have a Pentium M 735 1.7GHz and have found a Pentium M 755 2GHz SL7EM here http://cgi.ebay.co.uk/Intel-PENTIUM-...6.c0.m14.l1318

Will this work ok?

 

Can't open the link. How much is the 755 for..??
You can pin-mod the 735....Check out these guides.

Yes it will..

Download CPU-z and check what chipset you have

 

thats the same laptop my girlfriend has. I know hers has a 4200rpm drive in it, so you may want to upgrade the harddrive before upgrading the processor, since a faster harddrive will speed up loading times more than a slightly faster processor. Dont tell her, but I bought her the fastest ata/pata harddrive for her laptop, as a starting school again present

The processor you found will work fine.

K-TRON

 

The CPU upgrade might do less than you expect. It only really makes sense if you are maxing out your CPU often, which rarely happens for most users.

A fast harddrive, more memory and a clean install can often be more effective to improve performance.

 

Pin-mod is definitely worth trying, in my experiences with it I have had great results. My W3V is has pin-modded for quite some time and it still works so I don't think there is any high risks involved except for the modding process.

I also recommend getting a faster harddrive instead, notebooks back then were mostly 4200rpm drives(likely IDE). Jumping to a higher density 5400 rpm would be a huge increase in performance, the fastest available IDE drive is the WD Scorpio 250GB PATA/IDE drive.

 

It is fast yes, but the Samsung HM160HC is a bit faster. It has 160GB on one platter. It's a really good performer, my XP SP3 boots in 26 seconds of it (with 1.6Ghz Dothan).

K-Tron posted some benchmarks comparing the Samsung with the WD:

26 second boot with boottimer.exe:

 

Looks like I stand corrected, the Samsung is indeed faster! Was not on this board for some time so missed out on this. Nice Review K-Tron. I see you used my HD Tune bench

 

I have already upgraded to the WD Scorpio Blue 250Gb and reinstalled in the last couple of days.
I've also upgraded to 1Gb RAM which is the most I'm told it can accept.

What does pin modding achieve? May well still go for the CPU upgrade, could I also overclock it?

 

Pin modding can give you a 2.13GHz CPU for free. It's a bit more risky maybe.
There is a guide how to do it but can't quite find it at the moment. Check Andy's post above.

Overclocking is also possible.

 

Pinmodding is essentially overclocking. Your 735 would run at 133 FSB and will run at 2.26Ghz instead of 1.7Ghz.

Make sure your nc4010 is using the 910 Chipset(Sonoma) though, the pinmod won't work if it's anything else.

 

this is wat I have



IS that the correct chipset?

 

Nope. That's the ATi RS200m chipset. It may or may not work, I've seen some threads a few years ago discussing about the ATi chipset and some said there were success with it. It's worth a shot. Just follow the pin mod guide and see if it boots up.

 

And if it doesn't work I can just removed the wire and purchase the 755 instead?

 

actually, it doesn't look like it supports 133mhz, so the pinmod is not an option.

I think the highest supported processor is the 765, which is 2.1Ghz.

 

You could also try raising the FSB with software. It's easier than pinmodding because you don't have to open up your laptop.

Pinmodding has a higher succes rate though as far as I know.

ThePentium M 755 2.0GHz is £60 on ebay, is that worth the money as I can't do the pin mod?

When watching CPU-Z I do see it hitting the 1.7GHz when running applications

 

Honestly, you need to look at your CPU usage in the Task Manager. Unless it is hitting 100% for a good amount of time, there is no point to upgrading. You can't even upgrade beyond a single core processor.

I'd stick with pin modding and software modding.

 

Agree with Greg, the upgrade only makes sense if you are maxing out your CPU a lot.

I'd try the software modding first. Maybe it runs fine at 2.0Ghz.

 

Honestly, I would recommend to upgrade the memory or the harddrive first as discussed before as those would actually add noticeable difference to the performance of the notebook.

If your running XP, you may want to look into a utility called eboostr that can utilize unused RAM and use it as a file cache. I'm using that on my W3V and it's awesome, I wish there was something like this for vista(ready boost is garbage)

 

There is no point pinmodding if neither his chipset or ram are unable to support the 133MHz FSB of the modded CPU.

I have a M755 with a i855pm chipset. I've tried using SetFSB managed to get 2300MHz but it was very unstable and I can't do it anymore for some reason.

I do a lot of video encoding and that maxes out my CPU, makes doing anything else simultaneously impossible. And it takes ages.

 

2300MHz, i855. Which PLL in SetFSB..??
I remember PhilFlow had a hard-time overclocking his notebook's FSB via SetFSB..

 

Likewise, i have a PM725 on a 855pm chipset. I only managed to reach 2.1-2.2ghz through SetFSB (stock voltages). Any higher and the sound card would cut out lol

 

I have a Pentium M 735 pinmodded to 2.26Ghz on my 910PM chipset, it tops out at 2.4Ghz before causing major stability issues with SetFSB.

 

Yep I only got from 1.6 stock to 1.8Ghz.

But that could be enough for the OP since he has 1.7 and wants to get the feel of 2.0.

 

Which version of SetFSB should I be using?
