I just recieved an aopen board based on the Springdale-PE (Intel 865pe)
chipset and I whish to know:

1- if I can put 800mhz memory for a 400 or 533 fsb intel CPU and if yes,
what will be the effects of doing this

2- What will happen if I put 400 or 533 mhz memory for a 800 fsb Intel CPU

3- Does overclocking affects SATA bus and is it risky for data and hdd?

Thanks

You can physically put dual DDR400 memory into the board, and yes, it will
work with a 400 or 533MHz CPU, but even if the board has memory bus
multipliers that will allow you to run the DDR400 at its full rated speed,
you won't get the full benefit of the performance, as the CPU's slower bus
speed will act as a bottleneck.

Again it will work, and again you will have a bottleneck, although in this
case it'll be the memory slowing down the CPU, rather than vice versa.

Overclocking shouldn't affect the SATA (or indeed PCI and AGP buses),
because your board should have the option of locking all these at their
default frequencies, irrespective of the FSB.

However, to answer the second part of your point, if you neglect this option
and do choose to overclock your buses, there are risks to data integrity
with SATA, just as there were/are with Parallel ATA and SCSI systems.

Hello Nico,

1- I beleive there is no such DDR memory (800 MHz), maybe DDR2 which you
can't put on 865PE board.

2- If you put 533 mhz memory, then you will be able to overclock your fsb
and proc up to 266,5 for fsb
theoretic, and proc up to 266.5 x (whatever internal multiplier of proc is).
For example, if proc is 2800 northwood, it has locked multiplier 14, so it
will be 266.5x14=3731, but that proc is not heard of working that fast,
3.6 gig max, that is fsb 3600/14=257 fsb.

3- If you going to overclock, make shure that cooling is adequate. Stock
CPU cooler won't fit! Make shure that you lock AGP/PCI bus to 66/33,
so AGP/PCI bus stays down when u OC fsb, otherwise you can fry graphic card
and whatever you have in PCI slots.

And yes, SATA controller is attached to PCI bus, but should be no problem
if you lock AGP/PCI bus.

And. WHEN YOU OVERCLOCK, DO IT ONLY SMALL AMOUNT AT TIME, CHECK SYSTEM FOR
STABILITY, THEN INCREASE GRADUALLY, AND EVERY TIME CHECK FOR STABILITY. IT,S
A VERY PAINFULL JOB, AND COULD TAKE ALL DAY LONG TO REACH SYSTEM LIMIT (STABLEWISE).

Intel boards don't have most overclocking functions such as lock AGP/PCI

Very true, but what precisely does this snippet of info have to do with this
thread?
