Help me choose a P45 motherboard

post #1 of 21
Thread Starter 
What I am looking at:

ASUS P5Q $119
ASUS P5Q-E $149
ASUS P5Q Pro $149
Gigabyte GA-EP45-DS3R $144

Whats important:
  • Price
  • Heatsinks, I don't really want a board with heatpipes because I will be removing the NB heatsink, forcing me to remove all heatsinks connected to it.
  • TPM - Trusted Platform Module
  • ICH10R
  • PCI Express 1.1 or 2.0 at 8x speed or better (In addition to a single PCI Express 2.0 16X)
What is considered:
  • Dual BIOS's - always nice to have
  • 5 second Linux, not sure if I will ever use it, but it certainly sounds neat.
  • 2 PCI Express 2.0 - Although I probably will not use them, I would consider it. What I am somewhat confused about is wether these P45 boards advertised with 2 PCI Expres 2.0 slots are full 16x bandwidth on both slots through the NB (like X48).
Thoughts:

The P5Q-E has 2 PCI-E 2.0 slots, with one operating at 8x (I think ), a TPM, dual BIOS, and 5 second Linux. Its only draw back is that it has a heatsink.

The P5Q Pro has 2 PCI-E 2.0 slots (not sure their speeds ), 5 second Linux, dual BIOS, but no TPM. Considering that it also has a heatsink and as the same price as the P5Q-E I don't think I will be getting this board.

The P5Q is fairly basic and cheap. It only has 1 PCI Express 2.0 and no other PCI Express over 1x speed. It is cheap, it doesn't have heatsinks, and it does have 5 second Linux and dual BIOS. What it is missing is a TPM and of course the extra 8x PCI Express.

The GA-EP45-DS3R has 2 PCI Express 2.0 slots (one 8X), a TPM, dual BIOS, no heatpipes, but lacks 5 second Linux. The only downpoint to this is the lacking of ASUS's 5 second Linux.

If anyone can help me understand PCI Express on P45 that would be nice.

It seems like that P45 can do 1 PCI Express 2.0 16x or 2 PCI Express 2.0 8x. I got this information from Intel's spec sheets.

Did you read my post at all? I didn't really specify overclocking as a primary concern. Any P35 / P45 / X48 / X38 board can take a Q6600 to 3.60Ghz, which as high as I want to go.

This is correct. The P45 NB is limited to only 16 lanes of bandwidth. The X38/48 has 32.

According to Intel's spec sheet all P45 with ICH10R has a TPM, but the ASUS P5Q, P5Q Pro, or the DFI P45 board do not advertise it.
