CPU replacement Question

Has anyone replaced a one of these processors in red for one in blue and got the 800 bus?

Core 2 Duo T5250 1500 2048 667
Core 2 Duo T5450 1667 2048 667
Core 2 Duo T5550 1833 2048 667
Core 2 Duo T5750 2000 2048 667
Core 2 Duo T5850 2133 2048 667

Core 2 Duo T5270 1400 2048 800
Core 2 Duo T5470 1600 2048 800
Core 2 Duo T5870 2000 2048 800
Core 2 Duo T7100 1800 2048 800
Core 2 Duo T7250 2000 2048 800
Core 2 Duo T7300 2000 4096 800
Core 2 Duo T7500 2200 4096 800
Core 2 Duo T7700 2400 4096 800
Core 2 Duo T7800 2600 4096 800

 

I replaced my T5450 with a T8300.
EDIT: all that matters is you need a chipset that can go up to 800 ("newer" C2D supported ones) and that the BIOS supports the new CPU.

 

I've been doing some reading up on this and I'm not 100% sure the chipset plays a part in this speed, if I read correct, I believe this because "The FSB frequency is the speed (in MHz) of the processor front-side bus, with which the processor communicates to the chipset in the system" This came from the Intel site, If the chipset played a part in this speed, why wouldn't it say the speed the chipset was able to receive or process this data?
Saying that I do agree the bus it limited to the systems abilities as shown on this motherboard’s spec's showing the ability to run a bus of 800 and 1066 ( I know this MOBO is not compatible with the processor’s I posted, but I couldn’t find one that was)

Someone told me a 1066 bus processor wouldn't be able to run in such a system, I believe that person owe's me an apology, because it seems as you know less than you think you do and you shouldn't be telling people they're wrong when they're not!

 

I don't think I owe anyone an apology. You just fail to understand the fact that you're being confused left, right, and center.

I clearly stated on the other thread that a Santa Rosa platform(965 chipset) does not support 1066 mhz processors. Secondly, I also stated that the 1066 Core 2 Duo's physically fit into any Santa Rosa board as long as it's socket based. And I also stated that they may or may not boot up, and even if it does it will not work at the intended speed. Where have I stated otherwise?

First of all the specs of the motherboard you mentioned are of a Montevina (GM45) chipset, so it does support both 800mhz and 1066mhz FSB processors since both are of the same socket configuration. So you're way off topic there, and you need to look up the right info.

 

It got it on there (Processor Support for an Intel® Core™2 Duo mobile processor in an mPGA479 socket with a 800 and 1066 MHz system bus)

And you say it wouldn't go!
Just who is confused!

 

I don't think there's any chipset - or laptop for that matter - out there that will run the red processors but not the blue ones... maybe some oddball GL960s, but in general any machine that supports the blue chips should support the red ones as well.

 

Doesn't that chipset on that motherboard from intel say it runs both 800 plus 1066 bus ?

 

Before this gets a little heated, I'm going to state some very obvious points.

First of all, you seem to be confused as to which CPU's go with which chipsets. So here is a quick breakdown!


Napa Chipset (945) supports only Socket M Yonah (Core Duo) & Merom (Core 2 Duo 667 65nm)Processors.

Santa Rosa chipset (965) supports Socket P Merom (Core 2 Duo 800 65nm) & Penryn (Core 2 Duo 800 45nm) processors.

Montevina Chipset (GM45) Supports Socket P Penryn (Core 2 Duo 1066 45nm) & future CPU revision (stepping sometime this summer).

For more information read here at Wikipedia

 

Are you talking about the GL960? The GL960 only supports 533MHz FSB officially, but most of the time you can get it to run 667MHz FSB processors and 800MHz FSB processors just fine...

Only the 45 series chipsets (maybe the GL40?) can do 1066MHz FSB. It can, of course, also do 533/667/800 MHz FSBs as well.

 

Yes, but on the first post of your thread you listed 667FSB and 800FSB processors. How is that 800 and 1066 FSB?

 

You told me no 1066 bus can run in a 800 bus system did you not? That motherboard proves you wrong.
I'm thinking if this motherboard can, there might be others out there that can as well.

 

Oh my. You don't seem to read through all our posts, or you fail to even understand anything anyone here has posted as well as the thread before this.

I'm going to give up trying to educate you. Why am I even trying so hard to make you understand all of this?

 

That prove some motherboard are inter-generational!

 

945: 533MHz AND 667MHz FSB Socket M processors ONLY.
965: 533MHz AND 667Hz AND 800MHz FSB Socket P processors ONLY.
P45: 533MHz AND 667Hz AND 800MHz AND 1066MHz FSB Socket P processors ONLY.

P45 boards DO support two generations of processors, but 965 boards DO NOT.

 

Thanks, you prove it is possible.

 

That just proves my posts were correct?! 965 = Santa Rosa. hahumbug!

 

That list almost implies that Meroms would work on the P45 chipset to the untrained eye, which is why SPQR seems to think he has proved his point.

Intel still make budget based processors(not so much anymore though) ie; 533, 667 Penryns that can run on the P45/GM45 Chipset since it supports all Socket P. But to clarify, I was talking about the 965 chipset all along as the previous thread was talking mainly about upgradability of older platforms, and not the current ones.

 

WELL, you know it's POSSIBLE that you'll get a few mutant 965/BIOS combinations that will run 1066MHz chips at 800MHz, so you could technically "upgrade" in those cases... but I mean ultimately you still won't get 1066MHz on a 965 which is the point here.

 

Right, but I have yet to see any of these mutant 965 (lol) boards capable of 1066mhz or even recognizing a 1066 processor on boot up. That would likely be a very popular thread if someone has discovered one of these beauties, but it's been months since Montevina based processors released, and still nada. Theoretically, Santa Rosa with some tweaking with an unlocked BIOS is capable of 1066, much like Napa was capable of 800, but Intel won't support it, and neither would OEMs.

I have seen overclocks getting close to 1066 FSB on 800Mhz Processors, but that's still not like a T9400 on a 965 board. etc.

Anyway, I'm pretty tired trying to communicate with SPQR, so I'm just gonna let this thread just die.

 

i replaced a t5250 with a t7100 ES edition in my dv6500t

 

I didn’t mean to cause disharmony, rather get to understand the mechanics of computer components better, which has been achieved (for me anyway), the most important thing I’m going to take from this is although some things are possible others aren’t and that generalization on both sides can lead to disputation. Thanks to all for your input, it was annoying at times but useful anyhow.

I'm glad I hope it shorten your lifespan!
