The way to denote that these boards are Prescott ready is by the colour of the CPU bracket. Most of the new boards are shipping with the yellow CPU bracket which denotes that they are Prescott ready. All previous motherboards followed the following colour scheme...
Black – 400Mhz or 400\533 FSB (Northwood\Willamette) – No Prescott at all and no Hyper – Threading support on some models
Orange – 400\533\800 (Willamette\Northwood + Hyper Threading) – Prescott support through Bios update on some models
Yellow – 400\533\800 (Willamette\Northwood & Prescott + Hyper Threading) – Prescott ready
The previous versions of some of the motherboards that we have already sold do have support for the Prescott CPU, but will need a bios update. Gigabyte has added support for all other motherboards like the following...
Please note that most of these boards listed have the Orange CPU bracket and will work with the Prescott CPU after the bios update...
8KNXP series rev 1.0
8IK1100 rev 1.0
8IG1000 series rev 1.0
8PENXP rev 1.0
8IPE1000 series rev 1.0
8I848PL
8I845GV (Only support Prescott 2.8Ghz @ 533Mhz)
8S648FX/L
8S661FXM
We are still checking on the following motherboards for support...
8VM533 – 2.8Ghz 533FSB only
8S650GXMP – 2.8Ghz 533FSB only
8ST800 – 2.8Ghz 533FSB only

8TRS300M – All Prescott CPU's
All the Intel Chipset Gigabyte motherboards with the 1000 series or 1100 series will have support for the Prescott CPU. All other motherboards with the 800series or 900 series may not support the Prescott CPU. Gigabyte has not released bios updates for these boards as yet. We are soon to find out if there will be any support for the Prescott CPU's on the 800 and 900 series of motherboards.
Aopen
Aopen has not provided support for the AX4SG-Max with the Prescott CPU as well. The AX4PE may not have any support at all. We are still to find out if the Aopen XCube's with the i865 chipset supports the Prescott CPU. At present these is no support on these products.
Asrock
Asrock has not had any bios updates posted on the website for following motherboards for Prescott support…
PM266A – no guarantee
P4S650GX – 2.8Ghz @ 533FSB
P4VT800 – All Prescott CPU's
We still have to find out if there will be any support for these motherboards.
Intel
Intel has provided support for the 865 and 875 chipsets at this point and the supported motherboards are as follows...
D865GLCL
D865GLCLK
D865GBFL
D865GBFLK
D865PERLL
D865PERLK
D875PBZLK
At present there is no support for the Prescott on the S875WP1-E and the D845GVSRL. The last available bios update only has an update for the Intel 3.2Ghz EE CPU for the S875WP1-E. There is no mention of support for the Prescott CPU at this stage.
We have mailed the relevant suppliers and we are still waiting for them to check if there is support for the platforms not confirmed as yet. We will follow up and more feed back will be supplied at the earliest.
NB:
All products mentioned in the above list are products in our current product listings. If there is a product not mentioned in the above lists, please mail me so that I can do the necessary follow up…
