A8V, 4200 and 2x UAd-1s, load issues...

[Gary M]

Hi all,

Brief history:

Old system - A7m-266-D, 2x XP2400MP, 1.5 gb ram. RME 9652, 2x UAD-1.
New system - A8v Deluxe, x2 4200, 2gb ram, same cards. Various HDs.

With my old system, running the same load-test cpr in SX3.1, the uads would show a 10-15% lower load when in slots 1 and 2 than in any other slots. Eg, when in slots 1 and 2, uad load=75%, when in slots 3 and 5, uad meter=90%. Slots 1 and 2 on the A7M266-D were 66mhz slots as opposed to the others which were traditional 33mhz.

Now with my new x2 setup - running that same load-test cpr, I am getting the higher 90% load again, no matter which slot I put the uads in. Nice performance boost on the native cpu front - pleased with that, but effectively I'm losing three Pultecs-worth of power on the UAD front. Rather dissapointing.

Can anyone comment on this? Really can't see why this would be...

Gary.

I have had all kind of strange problems as of recently (upgraded to A8V deluxe). I have found (using the tested and tried method of trial and error, and a bit of help from Bret at UAD support) that by running the UAD:s in \"AMD-8131\" mode (yes, I KNOW that doesn't make sence), i get a bit higher CPU load, but a lot lower UAD load. This has also been verified by a friend of mine on a P4 with Intel chipset.

uad-1 project a8v deluxe & amd x2 3800 no probs

Hi,

I have only the simple plugins but My system has no problems.
My former 2x amd on a7m266-d was way worse because of my promise tx4 (DO NOT USE THE PROMISE ON THE A8V FOR AUDIO)

Gary: I have put together a little load test:

http://www.cutpaste.org/temp/LoadTest.zip

What readings do you get when running that? I get 98% on one card, but 63% on two cards. I have a very similar setup as yours (apart from me having a A64 3700+ and not a X2)
