For the GA-P35-DS4 rev2.0 is nothing change. I guess lucky people is "rev 2.1" and DS3 users.

In windows 7 X64, i can't play simple MP3 for God Sake. Before and after driver installation, naked windows.

By brother has 2 children, his old Asus computer runs windows XP. Interesting part is he has viruses and they avare. Everytime turn on the computer winlogon.exe (or similar) will warn and will restart if you click "OK"... So that message must stay with you. Children at least 30 stupid games installed. Here is his DPC check with sick virus computer




And my Gigabyte GA-P35-DS4 Rev 2.0... I have tried all versions. 3 different display card ati one of them.

Bios versions until F8 to F14. I have tried F8, 10, 11,12,13,14

I am told F14 should fix the problem. Also from this topic someone mention bios9 had a bug for my rev and model number

I do these with naked windows (nothing installed, no pci card, no usb, nothing) and after drivers etc installed :) And every other install i go and check DPC checker. Disabled everything including mouse i am holding.

Regarding your F5 suggestion i am not very sure if there is any for my revision (2.0) The site shows F8 to F14 and support tech would ask me to try or send me one. They told me F14 would fix, and disable something on the bios setting, i forgat right now but i did. Its peaks to 4000 right now.


I won't buy Gigabyte for sure. But i heard Gigabyte bought 51% of Asus :) What else i can buy now? Abit? MSI?

I would like to see picture of other boards DPC checks. I can't find any

Just found you guys here after getting the E-Mu 0404 USB for DAW work this week and noticing 'snap-crackle-pop'.  Getting DPC spikes up to 4000us correlated with sound degradation.  May try downgrading BIOS if no other solution :-(.

Has anyone with the P35-DS3L ever get a beta BIOS to try from Gigabyte?  I just sent them a request 10 minutes ago.

I was having similar DPC issues.  I have tried with and without overclocking, no help.  Upgraded to F14 bios, some improvement, but not great, any mouse activity triggered DPC spikes. Then a support person at m-audio suggested to disable the CPU Enhanced Halt (C1E) and CPU EIST. And boom - DPC is very stable.  Once in a while when opening an application it spikes all the way to 16ms (prior to disabling the switches it did not go up that far), but at least it only spikes once and then stays low all other time.  So to summarize, my setup GA-p35-DS4, intel 6600 overclocked to 3gz (just set the multiplier to 333), F14 bios and with the CPU Enhanced Halt (C1E) and CPU EIST switches disabled, windows 7 64bit. 
Hope this helps.

I got a new processor and used EasyTune6 to sort out some teething troubles. After this my soundcard started popping and dropping out like crazy. I thought the soundcard was dead but used the DPC checker and found a horrible latency problem with my Gigabyte motherboard, in the form of very regular spikes every 3 seconds, of about 13000 microseconds! While I was convinced for a day that it was a hardware problem, it was solved when I turned off Gigabyte's own EasyTune 6 program, which had installed itself to run in the background and sample all sorts of info about the hardware on a regular basis. THe program is great for checking CPU temps and overclocking etc, but it is also evil... Uninstall it after use!
