Replacing Centrino 1.73 for 2.13?

I have the HP dv4000 notebook with the Intel Centrino (Pentium M) 740 1.73 GHz Intel Centrino

Am I able to swap out and put in the Intel Centrino (Pentium M) 770 2.13GHz one?

If so, I'm thinking when the prices come down some, I'll make the swap.

 

How much is that 770? AFAIK, those prices are going to stay at their current levels, since no new processors are on the way until Santa Rosa.

 

Well, the new dual 2 core cpu's ought to drive the prices down some. But, what I was asking, can I make the cpu swap? Centrino 1.73 to 2.13?

 

Just something you may want to know.

Pentium M production will end in January, so they may become scarce a short time after that, so I wouldn't wait too much longer.

Just so you know.

 

Well, it shouldn't be too difficult as long as you have the skill. You might want to look for a service manual for your notebook, since it will have detailed instructions on how to take your notebook apart.

Basically, it might not be worth it. 23% increase in computing power, which I'm guessing isn't worth the price (about $400 right now).

I'm also going to guess that the price will not lower much more. Core Duo (and Core 2 Duo) processors came out quite a while ago, and the Penium M price drops probably already happened.

 

Well, news sources say Intel will cut prices on the Pentiums and Celerons running on the NetBurst microarchitecture more, but, when they plan to do so before they're completely gone, I don't know. I mean, maybe once production ends, but then who knows how supplies of them will last.

 

Pentium M is not NetBurst

 

The prices will stay the same if the supplys are low

 

Didn't say that it was.

I was referring more to the desktop chips (which are NetBurst), since I hadn't heard of the Pentium M price cuts as of yet.

Probably should have made myself a little clearer.





The prices will stay the same if the supplys are low

Yes, that's nothing new.

I meant when Intel plans to cut the prices is not known. When production ends, or right before the last of them are at retailers.

 

This hasn't been answered yet? ^^^
Is it hard to do, swapping the cpu
Has anyone done it yet with the dv4000?

 

Hard to do.. not really...



Will xyz cpu fit xyz model?

To the OP on a CPU upgrade..

1st step is to Check

HP PartSurfer to see if the SAME motherboard is used. http://www.partsurfer.hp.com/cgi-bin/spi/main

If it is the next step is to confirm that the BIOS will "see" the new cpu... Confirm that that model was SOLD with the cpu you're wanting to use.


BTW: If a faster cpu is $400... it's not worth it.


PS: How much is the price on that cpu you're talking about? You sound like another poster who was asking if a dv2000 /dv4000 would address 4 gig of memory who had not bothered to "price" the "upgrade".
(the upgrade being more than the cost of the machine)


Bottom line is a "new" machine would give better preformance for the $$$$ spent.


.

 

Now THIS is the answer I was looking for and then some!
Thanks for the info, I will check everything out. The current price is $400+ for the cpu. So I will wait until the price comes down, IF it does. At least I will know what it takes to do it.

Now, how do I give you credit "rep power" for this? I haven't done that yet...

Rep power, you click the little icon that looks like "bells"? a the lower left hand side of the page once logged in. (right above the Post Reply button)

.
BTW: Wish I could provide more info for you... Be aware that some people have upgraded the cpu on various machines without success.... something about the bios being "locked"...

Keep in mind "laptops" are basiclly a "sealed" unit, unlike a desktop 3rd party (non-oem) motherboard mfg's in which whose products bios is "updated" as new cpu's come out within a cpu's "famliy" a laptops bios is not updated..

Laptop mfg's wanting you to buy a "new" model....

You can also try "Intel" fo spec sheets on the cpu's you're wanting to use.... but keep in mind that the bios may not "see" a cpu, be able to use all the functions if it does because of the bios.

.

 

You never know sometimes as they can work too when their not supposet to... see this post from the HP forum:
http://forums1.itrc.hp.com/service/...03723&admit=-682735245+1163956961011+28353475

The HP tech I spoke with (Robert), said that the DV4030CA that I have cannot have the CPU upgraded. I went against this and decided to do it anyway. I bought a Pentium M 760, some Arctic Silver paste, and changed the CPU. It works PERFECTLY.

Let me write that again: It works PERFECTLY.

 

The above is a perfect example of HP "techs" not knowing "what" cpu will go into "what", or if a model will take an "updated" cpu. in 9999.99% of the cases when you call HP you will get someone reading off a "screen".. that screen of course saying xyz model is not upgradable... and as the last poster in that thread mentioned the mfg prefering people to "buy" a new notebook, instead of "upgrading"... The only time you might get some info being from a "geek", a "overclocker" /owner of the same notebook who has researched how to "hot-rod" it..

You won't be able to upgrade the video card, that's for sure, since its an integrated video chip, and not something like a mini-PCI module like a WiFi card would be.

The CPU I'm not sure of. I actually want to upgrade the CPU as well (I also have one of the DV4000 models, very similar to yours). I talked with HP support, they said its impossible to upgrade the CPU. This didn't make sense to me, since the BIOS in the laptop isn't coded for a particular CPU (to my knowledge). I already ordered a CPU off eBay (Pentium M 760) and I'm going to see if it takes it. I'll let you know if it works .

Well, I did it.

Let me write that again: It works PERFECTLY. The heatsink had to be cleaned of course, to be able to apply the new thermal grease (by the way, HP, you really should apply decent thermal compound to the CPU. What you had in there was pathetic).

Congratulation Cristian Asenjo

Your information is interested. Would you provide more information such as:
- Your previous CPU (is it Pentium M 730?)
- What is the chipset on your main board?

Thanks.

Thank you

The previous CPU I had was the Pentium M 730, using a 479 package (even though it has 478 pins).

The chipset I have, according to the Intel Chipset Identification Utility is:

Mobile Intel(R) 82915GM/GMS/910GML Express Chipset

end of quote.

Reason for that I'm sure is HP would rather sell you another notebook instead.

 

hi,i'm Gianfry from Italy,sorry for my bad English.
i need an help from you.
i have an HP nx 6310 and nx 7300,both with celeron M 4xx and chipset video intel 945GM family.
reading,hp guide-manual,they would be able to upgrade cpu with duo core T2400 OR 2500 ,fsb 667.
for nx 6310 i made a bios upgrade at version 0.8-the last one,but my upgrade do not runs!!
anyone can help me?
when i reboot my HP,with cpu-upgrade,the bios reads the new cpu correctly,and writes CORE INSIDE,but the boots cuts off black!
please help me
thanks much and have a nice day
Gianfry
