Lance your screen shot looks almost identical to mine after I rolled-back to F3, glad to see it worked for you. I've had two heavy-duty sessions since then and no problems, although things were stable for me before. I guess I just feel better now. BTW I vote you get Q6600, you can overclock it to 3.0 with ease, but you might not need to.
Yeah Ill probably get Q6600 since it is prett reasonable price now, and Im building a mobile system anyway, with this!!!! thermaltake lanbox Ill put the best performing cpu in the main unit, probably Q6600 Oc'ed to 3.0ghz ...and the 2nd best one in the mobile, which will probably be the E6320 Oc'd to 3ghz. Thanx for the fix for my board!

Sorry I didn't answer your Question after the Sonar Freaked out. I rebooted and it's back to performing well now, don't have a clue what caused that. There is a process that keeps popping up called winlogon.exe, but I dont logon or use those facilities.
Winlogon is part of MS's phone home project installed as part of the Windows Genuine Advantage garbage. Basically Winlogon will check your system every 14 days and report back the state to MS headquarters. Sadly it can not be removed in any real way and will be installed if you try to access Windows Update or many of the tech and download sites. It comes as a regular install package, or as a browser plugin. Fun eh?

A dead winlogon will kill your system - it's an essential Windows process (and the whole spiel about it being part of WGA and 'phoning home is BS).

Someone on the Internet also said it's part of the Windows Genuine Advantage stuff as well. I will live with it unless it becomes a proble,.

Mailed Janus from Gigabyte team support (janus.yeh@gigabyte.com.tw) asking for a fixed bios for my GA-P35-S3G and after one day only i got a new beta bios (F4D) that fixes my DPC spikes!!!!!!!! The problem is gone and seem that i got no other side effects but im still investigating. I've run a 35 minutes S&M memory stress test and i got no errors. My system (Intel Q6600 G0 quad core with 4 GB G.Skill PQ Series ram) is not overclocked so i don't know if i can get problems with OC. Seems that at Gigabyte there's two support centers,one of that centers it's full of dumbs,other fortunately not!!!

KWild,
That's great news! The beta BIOS works well on my system, too, except that I cannot change CPU voltage. I would think it would be easy for them to fix that, so I'm hoping for a good official release after their beta testing.
Did your audio performance improve?

Was this a problem only after flashing to the new beta BIOS?

If possible, could you flash back to your previous official BIOS and test it? We need to find the problems with the beta BIOS so Gigabyte can fix them for an official release.

Desperate Dan, I have in fact gotten that problem when closing SONAR, which I have traced to the fact that I have an iLock USB key with my KORG Legacy stuff that gives me problems every now and then. It's as if the device doesn't shut down properly when I close a SONAR project that is using the Legacy plug-ins. The way I shut down is to close the project first, wait a few seconds and then close SONAR.

Dan, Are you able to adjust your CPU (vcore) voltage in the BIOS and have it actually make a change when read with HW Monitor or CPUID within Windows while using the beta BIOS?

Hi Dan, I actually haven't overclocked this Board since I got the New BIOS, but I will try now and let you know what happens. I Did notice that the BIOS headings are in the wrong order, I assume they will fix that for F4. The M.I.T Section is first instead of General Settings in the BIOS list. Still the Latency fixed, that's good enough for me.

I Have just set mine back to overclocked at 3.2 Ghz (8 x 400, Mem 2.00, CPU Voltage 1.375) although the Voltage is set at 1.375 Hardware monitor and CPU-Z shows around 1.16/7 volts for CPU core which is way under the 1.375. I am going to push it up a little at a time and see if it responds and get back to you.On the Old BIOS I was showing around 1.34/5 volts CPU with the 1.375 BIOS Voltage setting.

That's what mine is doing, too. If you run Prime95, it will probably fail quickly. I have found that if I overclock using the F3 BIOS, then flash to the new beta BIOS, but don't clear the CMOS, it will hold the voltage you had it set at in the F3 BIOS.

Janus also sent me a Bios. first he sent me F12, which didn't make sense. Then today he sent me 13b which I need to try (this is for GA-P35-DS5(rev2.0)).
He seems to be a highly regarded individual on that TweakTown forum. Let's hope we are pushing things toward official production release fixes.

Hi bin68, All is not lost. Ask Gigabyte tech support for the beta BIOS, F4b. I have the same board as you, and I've been running it for a while with great stability and no DPC spikes. There are a few minor problems that I have faith they will work out in the final release. If you are not overclocking, then you likely will have no problem with the beta BIOS. If you are overclocking, do not clear the CMOS when you flash to the beta. On my system, the CPU (vcore) voltage doesn't respond with the beta BIOS. I am overclocked to 3.2GHz (8x400), and as long as I have the voltage set correctly when I flash to the beta BIOS, it holds it and everything is fine. I contacted Gigabyte through the Tech Support Page, but some people have gotten faster service by contacting Janus Yeh through the Tweak Town Gigabyte Forum. For some reason my link to it won't work, but you can google tweak town to find it.

I just want to say that I just installed the beta bios "13b" that was provided to me from Janus in Gigabyte Tech support for the GA-P35-DS4(rev2.0) and it works like a champ. with F12, and a barebones simple new XP Pro install, not even a soundcard installed, I was seeing regular speaks in the 700us range and occasionally some around 1500us. Installed F13b and now a "spike" is 40us, even when I am moving the mouse around like crazy...and often times it is under 10us.
I think Gigabyte is on top of the issue, whatever it is. Let's hope it makes it out into all of their board's production BIOS releases.
By the way, a Q6600 is in my board and its overclocked lightly to 3.01ghz and working fine with this bios, but I left the settings from the previous BIOS as suggested by Dan in order to retain the vcore settings.
Anyway, just wanted to report something positive.
