GA-Z68X-UD3P-B3 with RME Fireface 400

[Kraznet]

I built a new system using the Sandy Bridge 2600K CPU and the GA-Z68X-UD3P-B3 with 16Gigs of ram. The DPC latency is very low until I open my DAW which uses the Fireface 400. It then shoots up to just under 500us. I notice the new motherboards no longer use TI chipsets and have switched to VIA . I've disabled all the usual stuff in the BIOS and set the power options to performance in Windows 7. I have the latest F 4 BIOS. I'm thinking I may need to get a PCI E TI FireWire card. Anyone else noticed similar problems?

I have the same mobo. Since I use the Tascam FW-1884 it *must* use a TI chipset. I'm on F5 and get about the same results as you with a PCI-3 ADS Pyro card (TI Chipset).

I suspect that this mobo needs a better BIOS. I tried F6 and F7a. Both were worse. My mobo came with F3 which up in 1100 range. At least now, on Rev F5 I get ~500 like you.

Not happy as my previous Q6600 mobo was around 50 with the onboard TI chipset. I just "assumed" Gigabyte was a die hard TI Chipset user.

My bad. Sadly, I may never buy another Gigabyte mobo again.

Hi both.

Latency is normally caused by the way a program or driver is (badly) written. It doesn't release the kernal as it should and so causes a backup(latency)  to form in the queue. With this in mind I would check to see if there is a newer or better written version of your software/drivers.
