Does the 940GML chipset support Pentium Dual Core?

Hi all. I want to upgrade my wife's Compaq Presario V5204NR cpu. Currently, she has a Celeron M 410.

Firstly, I have done a BOATLOAD of searching on this and have hugely conflicting results, mostly stemming from the fact that no one really knows what chipset that they have due to how it is reported in most utilities. (i.e. It reports a long string that names ALL of the chipsets "945/943/940GML").

I recently upgraded MY processor (945 chipset) from a T2050 to a T7200. That was very successful. I thought that I would put the T2050 in her system. I upgraded to the latest BIOS which purports to support the T2050. I popped the known-good T2050 in her system, and got nothing. I put the M410 back in and the computer is fine. I think, therefore, that the chipset is definitely the plain-jane 940GML. I could not get a peek at the actual chip to verify.

So, now I am wondering (assuming 940GML) which processors WILL be supported. I am 99% sure that it will have to be a 533mhz processor. I am 90% sure that a T1350 Core Solo will work as there have been many people that claimed it does. I was hoping for something more powerful still, and came across the T2130. It is a 533Mhz Pentium Dual Core. The Wiki Page indicates that it may work:

"940GML Calistoga 82940GML (GMCH) ICH7-M January 2006 Celeron M, Core Solo, Pentium Dual-Core"

Other sources have said it will work, but I don't have anything definite.


Any thoughts on the 940GML with Pentium Dual Core?

thanks!.

 

I have an Dell Latitude with the GML940. I have tried HARD to upgrade the CPU. I had the Celeron 430 @ 1.73GHz. I have bought and tried like 5 different CPU's that said would work with the 943/945GLM. Everything from T2400, T5600, T2390 Would not even fit., T2080, Not one would work... The only upgrade that worked for me was the Core Solo T1350 @ 1.87GHz. I installed that, and it did work....

Here is the thread i started.

So, really, whats it worth to you? The Core Solo is nice, I have run Win XP, Vista, and 7 all on this laptop with out any real issues, so the core solo can handle the O/S with out problems, but you will not be editing 1080 Video, while doing 100 other things. Just will not work, but for everyday computing, Word, Internet, EMail, messing, forums, youtube, all works fine.

 

Ahh.. so you did (at the end of the post) try a T2080. I strongly suspect that T2060/2080/2130 will be HIGHLY variable per 940GML and BIOS... if at all. Do you still have that processor? Want to sell?

They are running about $20 shipped on ebay. I may just get the 2060, $13, and give it a try.

After my old T2050 did not work, I started looking. The 940GML ONLY supports 533Mhz processors, does not support Core Duo or Core 2 Duo processors. That leaves out the vast majority of processors that you tried or considered.


Now I am hoping against hope that at least some 940GML supports Pentium dual core (2060/2080/2130) and that maybe it was just your BIOS that did not support it. Otherwise, you are right in that the T1350 is the fastest processor that it will take.

 

The Celeron M 450 (2Ghz) is another alternative

EDIT
a few days old post where an OP tried to upgrade his acer laptop. He/she has an i940GML too ( link)

 

As far as i know , T1350 is ur best update.... IMO , the celeron M is not much of an upgrade...

 

How can you say that the Celeron M is not much of an upgrade?

The T1350 is clocked at 1.86Ghz while the Celeron M 450 is clocked at 2Ghz. That's 133Mhz more than the T1350

 

Yuck. I had really hoped that there was some kind of dual processor support with the 940GML.

I may try a 2060 anyway... they are so cheap. Otherwise, the core solo T1350 is it.

 

That would be your best bet.... If it works, then you can upgrade to something better, if it does not work, then you can sell the T2060... Let us know how is goes...

 

I've used the T2060 in a i943, and it's a significant boost over the T1350, or the Celeron @2GHz. And I know this is odd, but about the T2060, the Intel ARK page says it only has 1MB of L2 cache, but it has 1MB per core. I think mine got a 4.6 on the WEI rating. But then about a year later I upgraded to a Core2Duo T5500. Good luck experimenting!

 

The T2060 was sold as a Pentium Dual Core and as such it has only 1MB L2 cache shared by both cores, not 2MB as you think.
