Intel Application Accelerator

[SouljaAC]

Im debating on wheter or not to download this.

SOme ppl say to dl it, some say not to dl it.

I don't know what to do. Please help me in my decision, my specs are in the post about drivers that I did an hour ago.

Thankx!

I like IAA. Gives me a nice boost in Win2K. From what I hear, it's not as noticeable in WinXP.

Tell me what IAA is?

Free speed boost?

I use XP and I don't see any additional speed with or without it.

Would this IAA be good on an old i810E + Celeron 500 setup?

Nvidia dets dont like it. When I install IAA it says my card only has 32MB of ram when it gots 128!

Odd. My Ti4600 has 128 Meg as always.

IAA is simply just a IDE bus mastering driver for certain Intel chipsets. They use to named it Busmaster driver or something but somewhere along the line they changed it to Intel Application Accelerator.
Installing it should be no problem if your board is supported. You might actually benefit from the speed boost it gives for enabling your dma mode for hdds connected to the controller.

It is mostly an IDE driver, but has a little more.

Optimizations for Intel® Pentium® 4 Processors
Intel Application Accelerator enables a performance-enhancing data pre-fetcher for Intel® Pentium® 4 processor-based systems

I'm not sure on this, but I think you also need it for Hyperthreading support.

Here's a related question for the forum - is IAA useful if your primary drive (boot drive) is connected to an onboard RAID controller, rather than being controlled by the onboard IDE controller? I'm going to be setting up an EPoX EP-4PEA+ board soon, w/ the lone HD connected to a HighPoint 372 onboard RAID controller. In this case will IAA be of use, or can it potentially be a problem?

Nope. Wont do a thing. It only works on Intel IDE controllers. Why are you putting your HD on the HPT instead of the Intel IDE ports? Too many drives?

For the following reasons. One, it allows me to put my DVD and CD-RW as single masters on the primary and secondary IDE channels. Second, it keeps the optical drives off the same channel as the HD. Third, I've seen better HD performance connecting to the HPT as a single drive, compared to connecting it to the onboard IDE.

Maybe I'm all wet here, but this has worked for me on the last couple of systems, so I'm going w/ the same configuration when I set this system up. I got delayed in setup as I had to wait for Directron and/or Northgate Innovations to come through w/ an I/O shield, which was missing from the 4PEA+ box. FWIW I'm still puzzled why the 4PEA+ board hasn't been more popular, what w/ its feature set. It's getting very difficult to find online these days.

I agree. The 4PEA+ is a great board. It has the best feature set of any PE board. It's nearly impossible to find one now. I hope EPoX comes out with a really nice Sprindale PE.

So all i do is install this on my Athlon XP and i get a free performance boost.

IAA only works on processors with SSE2 (so far only the Pentium4 and soon the Athlon 64). It replaces the default chipset drivers with SSE2 optimized ones allowing better background use of the HDD and in some instances increasing performance.

 

[lenjack]

Works with Intel 800 series chipsets.

I have to say thanks for posting this thread. I was just screwing around and went to the IAA link that was posted. I saw that there was a new version and I installed it. It cured a problem I've been having for months.

Windows XP has been hanging on my first boot everytime. I have to hit reset and it reboots ok, but some of my startup programs don't start. Not a big deal but annoying. I haven't had a proper boot in awhile. I've reinstalled all of my drivers but never thought to reintall IAA. I did... and it fixed it! Perfect, quick boots. Thank you again.

Also, I did see an improvement in access times from the time I uninstalled IAA to after I installed the latest version. If you have a P-III or 4, install it for the hell of it and try it out.

One problem... Now when I try to go into the program I get an error. I've uninstalled and reinstalled an it won't fix it. The drivers show up in device manager ok so I may just leave as-is. I'm way better off now than I was before.

Ur welcome dude who posted above me, but I just wanted to know too.


But I wanna compliment Anandtech forums, cuz I was kicked from Hard Forum cuz they said I wuz spamming when I posted 3 posts in 15 minutes.
Thats so bull. So thankx anandtech peoplez!

Well, DUH! Since when has Intel created Athlon chipsets! If they have, that would be interesting, indeed!
