M55 latest bios flash --- any newer CPU support?

2009-04-03, 23:43 PM

I have an M55 8810 with a Core 2 Duo E6300 1.86 GHz CPU. The latest bios flash for my machine is dated January 09. There is a lot of information concerning bug fixes, etc. Is there any additional CPU support for the motherboard? I'm currently relying on the parts list for the model and motherboard as a guide for upgrades.

 

Thanks.

Solved! See the solution

There's no way of telling whether Lenovo added support for more processors.

It has been determined that the chipset (Intel Q965) on this particular Lenovo board will support up to the Core 2 Duo X6800 2.9 GHz Extreme CPU that came out in mid 06 with most of the rest of the E6000 series. At the Intel website they have a board (DQ965GF) with this chipset that supports the Q6600 and Q6700 Core 2 Quad and QX6700 and QX6800 Quad Extreme CPUs. All these CPUs run the 1066 MHz FSB. Apparently the potential is there, but perhaps the board isn't designed to supply the power to a quad core CPU (95-130 watt TDP). The proof for the X6800 (75 watt TDP) is mentioned elsewhere in the Lenovo forum where someone stated he had replaced an E6300 (1.8 GHz) with an X6800 and it worked fine. All the other CPUs in the E6000 series are 65 watt TDP.

In my Thinkcentre M55 - 8810 works a Intel Q6600 since 3 years without any problem.

 

But here are 2 things you should know:

1.) When you start your M55 after installing the Q6600 the machine give the message:

      "No processor BIOS update found." and a beep. You simply have to wait 2 Seconds and the machine starts

 

2.) Because of the missing processor BIOS update the cooler runs constantly at 70% to protect the unknown CPU from overheating. I use SpeedFan to fix that problem under Windows 7:

  http://www.almico.com/speedfan.php

 

Parameter for Speedfan:

Minimum value: 0%

Max value: 66%

Chip: SCH5127

Sensor: Pwm1

Bus: ISA

Adress: $541

 

automatically varieted on.

 

Thats all. It  works very well. Now I have a very fast Intel Quad in my M55.

I have M55 8805 with celeron 430 inside (very very very slow cpu)

So will it support q6600/6700 because its 1066mhz fsb?

 

Im having problems indetifying/finding my product on lenovo support page for any bios updates. Its like they forgot it still exist somewhere.

 

Have anyone tried high end 775 quadcores like q9600? Guess those are 1333mhz?

Unlike Asus or Gigabyte, where they support every processor possible with the installed chipset, the Lenovo BIOS supports all the processors that it sold with during it's production run (with the latest BIOS.)    The highest being an E6600.    Trying any other processor is a crapshoot.

Tried q6600 and e8xxx and ofc it wont work, didnt even post, just cpu fan at max.

Then i bought E 5200 fsb800 which should work because it says it supports e6600 which is even higher fsb. And it posts, but i get error

0167 no processor BIOS update found

*error boot sequence will be taken if no selection is made

But it wont boot to windows, just blank screen. I installed newest bios update for my thinkcentre m55 8805

What the hell do i do now?

No M55 sold with the E5200 processor (and therefore no BIOS support.)   Looking at the specs for your particular model of M55, it sold with the E6300, E6400, and E6600. 

 

M55 8805 spec
