Tech Support Forum - View Single Post - Intel D845GRG running at 400FSB instead of 533FSB

I have a Gateway/eMachines E Series E2000 system that I got for free.

The motherboard in this system, an Intel D845GRG, is stated on the Intel Site to run up to a P4 2.8 with a P06 or higher BIOS (the MB had P11 on it), and support a 533mHz front side bus. So I have removed the Celeron 1.8/400FSB that was in it and installed a P4 2.53 Northwood that has a 533mHz FSB, but the system is stating that it does not support this speed and has kicked it down to a 400mHz FSB, thus running the CPU at 1.9gHZ speed.

It will also not update the BIOS when using any of the programs from Intel, but I did finally get one from Gateway, after a few days of emailing back & forth, that did updated it to the final P19 BIOS they have. They also stated that the MB will run at 400/533FSB. I was hoping that would resolve this FSB speed issue, but no go, same results. The motherboard knows it is a 2.53 533, and Win XP Pro w/SP3 sees it as a 2.53, but it will not run at this speed. Here is the info on the BIOS update....

Bios Update for the Essex, Essex 2, Nimitz, Shiloh and Yorktown Motherboard, version RG84510A.15A.0057.P19
Supports: All Operating Systems

This MB also does not have an AGP slot, CNR slot, and some fan headers / jumpers.

The serial number of the system is 0028744157.

On the motherboard are the following numbers from two stickers located between the CPU and the memory...

1st one - 4000792
2nd one - ABRG24016730-AA-AB6577-301

I opened the case up, switched the BIOS jumper from Pins 1-2 to Pins 2-3 to get into the Maintenance mode, but nothing there that I can see that would affect the Buss Speed.

It took 2GB of pqi memory no problem, running them at 266. I guess that my question to anyone on here that can help is this....is this motherboard "crippled" and just flat-out will not run at 533FSB, or is there somewhere on the MB and/or BIOS that I can "throw a switch" to get this running at full speed that I am missing?

Thank You in Advance for any and all help that you can send my way! John
