[quote]Raistmer,

It's my own host, not development one (but still I like it too much to kill BTW ;) )




ok, I was just afraid there might be a problem with your terrific development work if this board's oc'ing could not be resolved.

Talk about sparse oc'ing options - there are at least as many oc'ing options in the manual as there are salt-water crocs in Kansas! LOL

I did pick up on one possibility - really clutching at straws here - you mentioned using ET6 earlier, but the manual shows ET5Pro in use. Perhaps ET5Pro works better with Q35 and later ET version doesn't?

Hey Raistmer, just throwing an idea out there for you;
If the mobo itself is not OCable, how about a BSEL mod then to fool it to run at a higher FSB? (asuming your CPU isn't already at 1600)

Could you give some more description of what BSEL mod is? I'm not familiar with this abbreviature.

It involves covering one or two pads underneath the CPU with a small piece of electrical tape, specifically the pads that tell the motherboard at witch FSB the cpu is supposed to operate.


Something along these lines.

I can point You towards what It is, But since I don't know what type of cpu You have, I can't narrow the focus too much so I'll give You two Google Search links on the subject, enjoy.

I see, thanks.
My CPU is Q9450, not included in list of supported CPUs for this modding.

As long as you have a motherboard and memory that can handle an FSB of 1600, you should be golden. Do this and your Q9450 should act as a locked XQ9770 (that is 1600FSB and 3.2GHz).

I looked at the specs for your motherboard at the gigabyte site, and it seems the board has 800-1333 FSB support. It MAY still support FSB1600, but it's not certain to work...

"tape the contacts " - what he proposed to do?
short circuit these 2 contacts or cut them away or what?

IMHO, cover contacts with isolation tape "izolenta" ;)

Uh-oh.

The mod page says the BSEL mod will not work on GIGABYTE motherboards.

relevent text:

"Read the Following Before Doing the Mod:

snip..

The mods won't work on gigabyte motherboards as they use the CPU ID to determine the FSB, not the pins on the CPU."

Well that options out, As Gigabyte knew someone would try this and so this idea is shot down in flames.

Too bad...What can I say, sorry but I'm an Asus guy. When it works the BSEL mod is great. Easy, non destructable and reversible.

Pity that Gigabyte board doesn't support this.
But from other side - maybe this fact just saved life for my CPU... :))))))))

Maybe there are some other ways? ...

try "ctrl+f1" in the BIOS

and you will see "advanced seetings" option or something like that

Done already - many memory tuning options but no FSB-related ones.

Probably it's the nature of Gigabyte motherboard based on Q35 chip. As was stated in this thread they are positioned as corporate-stable ones, that is, w/o OCing abilities easely available to users. That's why I looking for software-related ways for OCing.

BTW, there is another "hard question" about the same motherboard.
I chose it because it has embedded GPU chip. The reason was to use embedded chip for video output while leaving PCI-E nVidia board for CUDA-only computations.
But I can't configure Vista to use both devices. IT refuses to see both GPUs.
IS it possible? (to run intel's ebmedded GPU andnVidia 9600GSO GPU simultaneously?

Have you plugged monitor into both ports? With Vista have to do that & reboot. Extend desktop onto both. Then Boinc should see them.

I have always been under the impression you cannot use onboard+card for multiple monitor. So never tried. XP might handle it because will recognize card without need for extend desktop.

It really depends on the implementation. Most older onboard Intel video chipsets would automatically get disabled as soon as you plugged the card into the AGP slot. I know that some newer onboard graphics chipsets from nVidia and ATi allow you to use both, but I'm not certain about newer onboard Intel video chipsets. All I can suggest is to read teh manual and see if it mentions a way to do it. If not, then Gigabyte probably did not implement this feature into that motherboard, or Intel graphics still do not support this feature.

The way I see it:

1) reflash to another BIOS. BIOS that has overclocking features.

2) open the case and see if they installed FSB selector. FSB selector could be a set of jumpers or it could be a DIP switch.
