Here is what I think of my ASUS P4T-E in...... brief:
1.It's one of the fastest (together with the ABIT TH7II) in terms of performance for the P4/i850 combo and probably the leader in quality of design and components plus stability at every attainable speed.
2.There is truly an issue with the clock generators u will find in yoyr mobo probably because of the ASUS facility that your part was manufactured. If the retailer has stock of the mobo and he is willing to help you, do check that the chips near the RDRAM slots (small ones one next to each pair of slots) write ICS on them and not CYP. Everyone says they are more stable and better performers at high memory speeds...If u already own one and you learn the story now like I did 2 days before, I wish you are so lucky as I am finding the ICS ones in mine...!
3. My motherboard with the latest bios version (1005) already preinstalled and proudly written on it, DOESN'T SUPPORT stepless frequency adjustments of the FSB no matter what it writes on the box, in their site (product overview) or anywhere else u might find it. Many people in other forums are pissed with that issue too because we are all feeling fooled and some of them, that might have overclocking as a priority are ready to sell it for the ABIT.....
4. The bios chip is not socketed but surface mounted so u don't have the option to replace it after an unsuccesful flash....
5. OVERCLOCKING. Things have changed a lot compared to the prior P4T for the socket423 P4s but still, in general it remains quite of a hassle with them....
a. Jumperless mode-bios. That's where things are better for the P4T-E but not excellent. You have the 100-133 range avaialable in PREDEFINED STEPS while in the P4T u could go only up to 120 jumperless.We would like a bios update that would allow stepless increments up to 150 or 200Mhz plus adjustments for the AGP and PCI bus other than the default 2/3 and 1/3, as all decent overclocking mobos so everyone can try the legendary stability of it, if needed. Don't be fooled by what is written in the book about the FSB possible configuration range (100-227!!!!). Crap again like the stepless story......
b. Dip switches. Here apply exactly the same settings as the P4T due to the same clock generator, but the thing is that ASUS delberately(?) hides all the info for settings above 110mhz in the manual!! So , you have to download the P4T manual to overclock up to 156Mhz FSB through DSW and access the so much valuable AGP-PCI multipliers. Note that there is no way to manipulate the CPU core voltage this way unless you modify the chip or the mobo by wiring.....
