I Solved My Echo Audio Latency Problem

I flashed my BIOS, installed new chip set drivers and did a clean install of Vista and that fixed it. It still has 11 ms latency but it is rock solid now and I don't have to use ASIO4ALL like I was before. I was about to send it back. I really did not want to return it because it has ADAT so I can hook it up to the SFP. I can not afford RME but my next card will be a PCIe X1.

so it was a chipset driver issue? Or bios.. these things are always so confusing. glad you figured it out.

It didn't make a difference until I did a clean install of Vista again. Probably it's not a good idea to give up on anything too soon.

Any time something goes wrong, Vista will always get the blame because it has a bad reputation.
I flashed the BIOS because I read an account of someone solving his audio problem this way. It didn't make a difference however, until I installed Vista again. Come to think of it I never installed the chipset drivers again after I reinstalled Vista so it must have been the BIOS. I am tempted now to do the chipset but not until I backup everything! Another possibility is that the Microsoft drivers are better but I think this is highly unlikely.

no, they can be unistalled in the device manager, and reinstalled on reboot, or by doing a "repair"(NOT with the "recovery console") install.

Downside to 'repair' installs is that unless you use install media that has been slipstreamed up to the current MS updates, you'll likely overwrite 'updated' files with older ones (messing up your 'updates').
Most likely what occured with a new BIOS flash is the ESCD (Extended System Configuration Data) store was reset, meaning that your hardware allocations could have been shifted around enough to resolve potential conflicts. This can be especially important if you do your initial build & BIOS configuration *before* installing your Scope cards (or other hardware). You can reset it manually too, by using the option to reset it in the BIOS, which is often a good idea when you've installed new hardware. ESCD is a BIOS-level datastore that stores 'PnP' info that gets handed off to windows, a way to keep things permanently mapped to the resources that have been allocated so things don't shift around on new boots, causing windows to confusingly load new drivers for hardware that hasn't changed.
It's also possible that the BIOS update may have resolved other hardware issues by updating the firmware for other devices (onboard LAn adapters & the like). Again not uncommon...

I installed the Intel chipset drivers and that did nothing to improve latency even though it said it was installing PCI drivers. I believe it may have helped a couple of my USB ports.
This BIOS flash was the main thing.
Note to internet:
Gigabyte EP45-UD3R motherboard + PCI audio latency
P.S.
Now I added the ASIO4ALL drivers and reduced the input latency to zero!
Update:
I figured out now that ASIO4ALL is faster because it is using WaveRT, the KHZ can not be changed. I am sure I installed the Echo Audio WaveRT drivers though. It must be doing a live change which would slow it down. I would rather have lower latency!
