Hi everyone, here is another problem which i really hate about this motherboard, it says it has dolby sound onboard, hell this oboard sound is the worst ever cause it doesn't work (i know i should get a creative or asus sound card but that's why i bought ud3p instead ud3r for the sound) In vista 64 sp1 when i use any realtek drivers the sound is not installed properly cause under realtek hd audio manager it doesn't know how to configure 5.1 settings right. It disables the rear speakers and it enables the sides speakers which are only available on the 7.1 ch sound speakers. The windows drivers configure the sound as 5.1 sides off rears on without any issues (detected also on the winamp output plugin) i even have speaker fill option available. The sound chipset is ALC 889A the same as on my brothers ep35-ds3r and to him the sound drivers are installed corectly on vista x64 sp1 as it should be on 5.1 configuration, sides off and rear on and also on the realtek console it has speaker fill avilable which i don't have. This is one hell of a buggy board and gigabyte doesnt have a support forum and they don't seem to be aware of the problem so i dont know what to do cause the sound doesn't have any amplitude and is very low in any way possible. I really dont understand why they didnt @ least fix the sound on this board. My speakers are logitech g51

An issue with sound and it is a "buggy" board? Sounds like some frustration there. Computers, no to alike, often no explanation as to why soemthing is happening. Get used to it.
Here is a link to a forum with Gigabyte representation. Some good info available, as there is here.

about buggy let-s not forget the 333 mch strap, and some voltage blanks ,very picky about memory my ocz 4gb reaper 1066, can't do 1066 pl6 on this board if it's not @ default settings, pLus some picky as hell damn references.
Thanks for info i will look into it, did youre sound drivers installed corectly on vista x64?

Kemocer.here are the the straps and their dividers.
200 strap: 3:4, 3:5, 1:2
266 strap: 4:5, 2:3, 1:2
333 strap: 1:1, 5:6, 5:8, 1:2
400 strap: 1:1, 3:4, 2:3

example:333strap-1:1=2.00B / 5:6=2.40B / 5:8=3.20B

thanks a lot

Don't know why I just noticed it but when overclocked does anyone elses board do this....When I first turn on in the morning (after shutting down at night and switching main power center/surge protector off) it does a quick power on (about a half second) then off then back on in about a second or 2 and continues to boot. It only happens when OC'd. Is it just my board or do any of you have this as well? Thanks!

Yes, no problem at all. It is a bit of a custom install, as I used Daniel Ks set to access THX console.

Installed my HR-05...

The mosfet heatsink can be removed from the heatpipe. Remove both heatsinks from the board and just keep twisting and pulling until it slides off.

HR-05.




The Gigabyte faceplate is held on by adhesive so I took it off...




And put it on the new one!!




All that red is ruining this blue theme I have going now.

@ stn0091,

I am looking to do this as well, did you use anything like WD40 or other oil??

Thanks,

Got a new Q9550 (had an 8500 that I hit 4.2 with, was doing more video work so i decided to get a quad core) , this oc is with 8gb of ram, havent stressed it so far but its looking good!

[lilneel12]

i need some more ideas,
anybody?

bump, no one have any ideas for tweaking this setup?

[pangingIII]

Bout this moding of the cooler :
I've changed the pad of the NB whith AS5 and sanded the SB cooler which wasn't plane at all
Than it appears a massive hole inside, seen after a few second of scratchin' ^^ don't know yet what it will change, but I feel it's better now

First look with my E8600 : some 570 FSBmax with all on "auto" , I'm gonna digg for now W&S

Hey guys sorry for the stupid question...

if i update to bios F9 (i have F8) i lost all my OC profiles ?, i have them on a pen drive, in case that i flash to F9 can i load them ?

Anyone saw any improvements on bios F9 in quads ?

Cheers
Sergio

Yes

i have them on a pen drive, in case that i flash to F9 can i load them ?

With others versions it's work.

Woww nice temp m8te !! Which cooler PangingIII ?

[OC Nub]

What kinda temps running small fft's Pangin? Very nice Overclock

[pangingIII]

Thanks. i use thermalright ultra 120 extreme (silver color one)

Thanks.
it would stay at 75C+ and more for something like ITB test i believe,
i didn't want to run them until i get a better cooling maybe.
