AsusA7A266 doesnt like AMD 1600?

I recently sold my Amd 1.4 so I could buy an
XP 1600 thinking that it might be faster.
I recently noticed while playing an MP3 that
every minute it hiccups. This also happens with
AVI, MPG, WAV, Soundforge, and Diablo2. I cant really tell if its happening in Photoshop.
These files are not corrupt and be accessed and
played fine from other PCs on the network.
I have played regular music CDs in my cdrom and
they play fine. I put MP3 cd in my cdrom and
it again hiccups. Ive burnt these MP3s onto a
cd as music (not MP3) and no problems.
Im using an ASUS a7a266 mb with the latest BIOS
and still the same problem. Ive run DXDIAG
(DX 7.0 is what im using) and tested the sound and music. Sure enough it hiccuped, but DXDIAG
doesnt notice it and ends the tests saying
everything completed successfully.
I used Norton Ghost to bring my PC back to a
fresh install and still the same prob. This must
mean that the problem is hardware, right?
Stats: Win 2000
AMD XP 1600 (Problem started here)
ASUS A7A266 MB
Maxtor 80Gig HDD
Adaptec 29160 SCSI card
Seagate 20Gig HDD
512 DDR Ram
Soundblaster PCI128
Matrox G400 Dual (32MB)
3Com NIC

Please tell where to go from here.

Woo, there last BIOS update was released on my birthday... 24/10/82 - im sure the XP chips where released after that, i think the XP chips have the morgan core, but im not sure, someone please correct me if im wrong, but have you downloaded the latest drivers for the Creative card?

for anyone wanting the BIOS update it is<a href="http://cgi.asus.com.tw/cgi-bin/dl.asp?filename=mb/socka/m1647/a7a266-e/ae261007.zip" target="_blank">HERE</a>

THe release before that is <a href="http://cgi.asus.com.tw/cgi-bin/dl.asp?filename=mb/socka/kl133/a7vl-vm/100la.zip" target="_blank">HERE</a>

But if it worked fine before, i'd say the chip isnt fully compatible with the Mobo.

Good Luck.

i have the same board ,,,,was hoping to do a simular type of upgrade to ,,,,,i have the box here,,and it state "palmino ready" ,,,i believe this is from bios ver 1.7 ,,,,i have upgraded bios to ver 1.9 ,,,,but cant remember which site it came from
the later bios upgrades inc the fix for ati vid cards

good luck freddy

latest asus a7a bios available here: <a href="http://www.amdmb.com/files.php" target="_blank">http://www.amdmb.com/files.php</a>


from what i read ver 1006 and above cover palaminos + morgans ,,,,,,,my board 7 week old came with 1007 ...

Only hiccups with mp3? Dma.

You've gotta remember mp3 playing is using cpu a lot. I notice you've got a scsi card in there as well, is system on it or anything that might be in the mp3 process? I take it that it doesn't like games either?

Via chipsets do not like an ide/scsi mix, its how the Southbridge works to intercept the wait signals that causes the problems. So if anything on the PCI bus is active then the scsi card knows cos its own bios is loaded, so it'll make the cpu wait another cycle until its sure that whatever is done - hence stutter.

Streaming audio from cd's is different and requires very little cpu activity and I don't think that uses DMA at all, because you only need 1x for audio don't you?

Most CD units are dma on demand and default to some PIO mode other times.

I hope you got full price for your 1.4 'cos none of the xp chips are that good under 98 or 2000, no sse enabled instructions there, you want like the name implies xp, then you will get your performance improvement. Potentially this could be your problem, I don't think AMD will be very happy about this, but all the xp chips I've put in under 98 seem worse than the equivalent athlon, this may be to do with how the chip executes, but I just can't say (No doubt I will now be endlessly quoted on that one..!).

DXdiag is pretty naff for sound testing all it does is ask if you can hear it, and looks at all the files, which no doubt you could have done yourself.

After all that, all I can say is latest drivers, bios and try without the scsi if that's possible.

Re the suspicion about the board not being xp capable - if it gets into windows you can be 99% sure its ok, as long as it sees it correctly at post.

Sorry I wasn't really that much help, but at least some info?

I posted to you before in another section but read <a href="http://forums.windrivers.com/cgi-bin/forum3/noncgi/ultimatebb.php?ubb=get_topic&f=17&t=007569" target="_blank">this</a>. It is a problem that I had and what I had to do to fix it.
