Can't upgrade the 533mhz FSB T2250 to Core2Duo???

[dfichtner]

I bought an HP dv2050us computer with a T2250 CoreDuo at 1.73ghz. I bought it, reading online that I can upgrade a CoreDuo processor to a Core2Duo. Now I find out that it has a 533mhz FSB, and all of the Core2Duo chips run at a 667mhz FSB.

So does this mean I can't upgrade to a Core2Duo chip?

The HP tech in chat said I can't, because the pins won't match. I'm a little shocked. The motherboard specs/chipset seem to fit what will work for a Core2Duo chip???

I'm a little shocked, because I can't find any chatter on the web AT ALL about people not knowing you can't upgrade these 533mhz FSB CoreDuo chips to a Core2Duo.

Does anyone have a different answer than "NO!"

Thanks!

umm the coreduo chips are socket 479 and are meant for mobility (laptops?) where the core 2 duo's are desktop processors and are socket 775. and they actually have 1066 mhz fsb. There is no way for you to use these new processors in your rig.

Edit, i think your thinking of the Yonah chips, which are 667 mhz...

sicloan is correct... and not that the pin configuration won't match, but the core2duo doesn't even have pins... I have no clue where you read that or perhaps there was some sort of misunderstanding... but simply... no way. Even as sicloan stated, the FSB speed on the core2duo is actually double the coreduo but even if the core2duo had the same pin configuration you're going to push SO much more heat that the stock laptop cooling would never take it.

So does this mean I can't upgrade to a Core2Duo chip?
Conroe? No. Socket 775 no pins on CPU. Merom? Possibly. Socket 479 pins on CPU. I have upgraded my Mac mini Core Duo (Yonah) to Core 2 Duo (Merom) with no problems. Which chipset does your machine use? Check out the article here (http://www.anandtech.com/printarticle.aspx?i=2808). Feel free to ask further questions if you need more explanation after reading the aforementioned article.

[dfichtner]

Of course, I mean the mobile chip? Mermon? That's a Core2Duo chip, as well, right?

Here is what I got back from HP Support:

Thank you for contacting HP Total Care.

I understand from your message that you have Intel 2250 dual-core chip,
which is at 1.73ghz with a 533mhz FSB and now you want to upgrade the
FSB to 667MHZ. Let me assist you in this regard.

I regret to inform you that what our representative told was correct.
You can upgrade the processor to any of the following processors.

T2050 (1.60GHz)
T2250 (1.73GHz)
T2300E (1.66GHz)
T2400 (1.83GHz)
T2500 (2.00GHz)
T2600 (2.16GHz)

But FSB is the circuit that is integrated on to the motherboard which
is not possible to upgrade. This may disappoint you. But I convey my
apology for the inconvenience caused to you in this regard.

Please get back to me if you need further assistance and I will be glad
to assist you.

Sincerely,

Rebecca
HP Total Care

use cpu-z to find out what chipset it has on it. mermon is the mobile version of conroe. lower speeds and lower voltage but with socket 479, going from core duo to core 2 duo may just require a bios update for the lappy. As long as the chipset supports the faster fsb. the mac mini uses such laptop parts and fugger over at xs that got a mermon ES droped it right in and it worked perfectly. you just need to do a bit of research.

[dfichtner]

Thanks, Evil -- that's a program I needed...

Here are the results, which make me think I CAN upgrade. What do you think? Would it be capable of 667 FSB just because it's the 945GM chipset?

Would it be possible that HP is purposefully limiting it in Bios so that people cannot upgrade? Why would they do that? Or do you think they just aren't that far along yet in upgrading the bios, so they tell their techs that "it can't be done."? Actually, this exact dv2000 computer comes in a 667FSB version with the 667FSB CoreDuo CPU, as well. From what I can see on their website, the bios is the same for both computers.

I still think HP is wrong...

Here were the results:

Aha... I am coming up with this after searching the Intel site. Support for both 533 and 667 fsb. Am I missing something? Me thinks HP is stoopid...

Looks like it would work to me.

[Evilsizer]

ok so then if they sell the same model lappy with the option of either cores CD"yohan" or C2D "memron". Then it is just a simple open up laptop and drop in replacement.

[The Coolest]

Should work without any problems.

[dfichtner]

I think they just haven't updated the information for their online support people. I don't plan on upgrading to a Core2Duo for at least a year anyway. I would like to do that with Vista, and also add a 7200RPM hard drive at the time (if it doesn't sap the heck out of my battery life).

I also see that some of the CPUs they quoted me as upgrades for this machine are 667mhz FSB.

My big concern through all of this has been that the CoreDuo I now have is not 64-bit. Not important now, but I believe it will be in a few years. I just invested $1,300 in this computer, and another $170 on the notebook expansion base, and plan to keep it at least 3 or 4 years. So I was a little shocked when HP told me I couldn't upgrade the CPU to a Core2Duo.

"The Coolest," I see you are in Israel. I hope you and your family are safe.

[dfichtner]

Well, they don't sell the laptop with a Core 2 Duo yet, but I imagine they will soon.

[MadMan007]

They probably told you it can't be upgraded in order to try to sell you a completely new laptop :p

Are you able to get in to the BIOS? If so check what settings there are, you might want to make sure there are memory dividers, bus speed locks etc which would keep the other components from preventing the upgrade.

there is no tweakable settings in laptops from what i have seen as far as ram goes. As the laptop will use the SPD info and set mem speed and timings by it.

all these here support C2D laptop cpus, how so... the chipset supports the FSB and it needs a bios update. The same thing does apply to a laptop as long as the chipset has the FSB to support the cpu. Reguardless of what HP/Dell/ect tells you they will more then likly have a bios update for the laptops. It will save them money then releaseing a whole new line when alot of the current laptops support the C2D now. it is the only logical thing to do. As i dont see them just throwing money out the window to redsign the laptop to be like OMG IT SUPPORTS INTELS NEW C2D.

[dfichtner]

Yeah, well I'm pretty sure it's going to work. Bios update needed? Not sure! That would be the big question. Did that guy who dropped his into a mac need a bios update?

As for 667FSB capability, it definately has that. I sort of laugh at their e-mail, because in one sentence she told me it wouldn't support a 667FSB, then went on to list all of the processor upgrades I can currently do -- guess what -- including some with a 667FSB.

So you guys are pretty sure I'd need a bios upgrade to recognize the new Core2Duo processor, eh? I'm wondering if HP would bother to offer that by this time next year. Is that sort of thing common for a laptop?

And to answer someone's question, there are almost NO settings in bios which can be changed. The date, and that's about it!

It will work. If I could find the link I would link it.

Thanks. The big question being if I need a bios upgrade or not. I wonder if HP service ever upgrades processors in notebooks for people?
