Gigabyte GA-8IHXP overclocking problem

[ferrus]

Hi,
I have oc problem with ga-8ihxp i hope somebody can help here...
I would like to use the integrated sound chip but it seems it does not work when the board is overclocked.Even with 103MHz FSB! Is it a driver bug or i should use a pci sound card instead? Or any idea what could be the problem?

Strange... if there is an option for it you can increase the I/O Voltage (or PCI Voltage) a little to see if that solves the problem.

My PC eats so much money that I'm in 'desperate' need of it to buy PC3500 RAM, help Svol with his OC project!

Thanks, I will check.

The PCI voltage is not adjustable. I tried all the possibilities with the CPU core voltage (max 1.7V) and "Over RIMM voltage" & "Over AGP (1.7V)" but it did not help. Strange, but sound works well when I go up to 133 MHz FSB - unfortunately windows becomes very instable.
After a long fight I managed to reach 105MHz FSB: sound works & win is stable. But I expect much more from tihs board... any idea???
Anybody knows how to set memory type to PC1066? When i set fsb to 133 bios still allows only "AUTO" "PC600" and "PC800" options.

With 133MHz FSB the PCI divider will probably go from 1/3 to 1/4 of the FSB... thus making 33Mhz again.
Maybe if you flash the BIOS with the latest version those memory settings will be added?

Checked BIOS release: the newest is in the board.
Unfortunatly PCI divider is not changeable manually...
So under 133FSB the PCI is the problem, above the CPU or the RAM.

Finally I was success: now the CPU is running on 2.4GHz, CPU core voltage 1.5V. I sat the RAM type to PC600 and fsb to 133 MHz --> RAM speed remained on 400 (3*133) just like PC800 mode (4*100). So CPU speed is 2.4GHz, sys bus 533MHz, RAM 400MHz.
