Motu 8pre with 8GB of RAM / XP x64 (SOLVED)

Hello,

I just bought a Motu 8pre, and it does not play sound when I have 8 GB of RAM installed. The sound output gets very crackled and distorted. It seems that MIDI input still works. I test both in Winamp, and in ASIO mode in Reaper.

I have 4 sticks of 2GB of RAM, in an Asus p5n32e sli plus motherboard. Now, if one stick of RAM is removed (leaving 6GB installed), then the 8pre works! It also works with 4GB. And with 8GB in XP 32-bit Professional.

I have been running this machine for a year with 8 GB of RAM, and it is stable. I did run Memtest86+ and Prime95 for over 72 hours, with no errors. The machine dual boots XP32 in which the 8pre also works. The RAM is definitely good and adequately cooled.

I have a P5EWS with 8GB and both Vista 64 and XP 64 do the same thing with an 896HD. XP 32 works but using that with 8GB is silly since only 3.25GB are recognized.

I certainly hope they come up with a fix for this soon!

Thanks for the reply, minerva. Does your 896HD work in XP x64 if you have less than 8GB (e.g. 6 or 4) of RAM installed? Just asking because my 8pre works in that setup.

I have four 2gb pieces and if I boot with one (2gb total) it works perfectly. If I boot XP Pro 32bit it does not matter. Vista x64 is the same way so this is a common problem. Sometimes there is no sound playback, others it plays but sputters badly.

Ah...so in Vista x64 you get sputters with 4GB of RAM, but not with 2GB?
But XP Pro 32bit sounds good with 4GB of RAM?

Yes that is because the 32bit OS will not address more than 3.25GB (on this board) RAM.

The drivers are clearly busted and we need a fix sooner than later!

Great news. If you contact MOTU, they will give you an updated driver that should fix this issue.

Ridiculous.

Would you be willing to send others the new drivers? I'd be willing to host them for download. MOTU's customer service is notoriously lacking for this type of stuff in my experience.
