I don't think one is better than the other.
Some will say ACPI, others will say standard PC.
I've been a huge fan of standrard PC, but now that I'm back on scope platform, I did a reinstall with ACPI turned on, and no problems so far (I have 3 boards in my system).

I am a standard pc fan as well, but
I think i'm gonna install in ACPI.
To get advantage of hyperthreading and maybe become a little quicker with two or three programs running together. Nothing sure 100%.
Thanks!

there is NO advantage to hyperthreading worth speaking of. indeed, it often leads to instablity. please don't fall prey to marketing scams....

What kind of instability? crackles for exampe? There must be some basic advantages of ACPI over standard pc.

Hyperthreading is not the same as ACPI. Turn it off regardless of whether you use ACPI/standard PC. It leads to instability with Scope and other software too. The performance gains are pretty questionable at best.

I've found ACPI to work pretty good, even on an old Dell P3 laptop with a Magma/Pulsar system attached.

For modern motherboards I recommend it. Standard PC can work pretty good (maybe better) but I've seen odd quirks happen sometimes (for example, if you have a modern motherboard there simply aren't enough IRQs for all the onboard devices in standard PC mode).

The best thing to do is just try it. There is no substitute in this business for cold hard experience. That's the way it is with computers unfortunately.

do you consider abit ic7g 478
as a modern motherboard?

Yes. By the way the comment I made about experience in my last post was not meant in a negative way - from posts I've seen on this forum some people seem to have better results with Standard PC than with ACPI, *and* vice versa.

Therefore, with things like this there are sometimes no definite answers. The best thing to do is try one and see if it works for you. If it doesn't try the other way and see if that's any better.

My personal hunch is that ACPI will be better for you, but definitely kill hyperthreading.

standard pc kills huberthreading as i can see.
Why should i try with acpi then if i disable hyberthreading?
because of more irqs?
I thought that the real ones are 15. On acpi these are "kind of mixed" and make the rest irqs. Not sure! i would appreciate some help here :???

ACPI is a system management system, it's not just about IRQs.

All modern motherboards are designed to be run specifically in this mode.

Standard PC is a 'legacy mode'.

Do you advice me to disable hyberthreading from BIOS before installation, or try install with hyberthreading and disable it later(if i have problems)?

Disable it before, you don't want Windows installing with the multi-processor kernel.

if hyper-threading processors do problem with scope than its 100% worthless to buy one. is duel core and hyper-threading processors are the same? does it gonna work with pulsar?
Thanks

To be honest, i haven't seen much difference between acpi and standard pc. Some actions are faster with the first and some other actions are faster with the second. I have the feeling that standard pc is a little more stable. It gives you the emotion to be sure, and work without being nervus. On a pc like mine atleast.
