Asus A7V333 : Question about OCing

[BentValve]

I have had this board for around 6 months and changed CPUs to an Athlon T-Bred which I found out would OC pretty good...I cranked the FSB up to as high as 163mhz and the system ran good, however I also dont know anything about OCing and I did not realize that this is too fast for my PCI and AGP ports so I lowered it to 155mhz.........but then I realized that the PC2700 is only running at 310mhz not 333mhz.....I backed the fsb down to 133mhz and cranked up the multiplier instead. Now the ram runs at 333mhz but I wish I could crank up my FSB a little more without
it affecting the ram speeds.
There are no options to change the ram speeeds (as far as I can tell) other than the CPU/memory ratio which can be set at auto or 1:1.

Please tell me how I can run my ram at 333mhz and my fsb at 155mhz oir higher. ....or is this just not possible?

TIA

Lower the cpu multiplier and crank the fsb to 166MHz, then you will have a 1/5 pci divider. Bump the DDR voltage up a little bit and start with relaxed memory timings, then test and crank the timings up slowly.

I did that and SiSoft Sandra still says my PCI and AGP bus are too high,.

AGP is showing up at 84mhz, 4x84mhz (336mhz)
PCI-- 1/4x 42mhz
FSB and Ram -- 2x167mhz (334mhz)

Is there a manual setting in the bios to set the pci divisor to 1/5?

Hey I have the same problem! Does the a7v333 support the 1/5 divisor or not?

Sandra says it doesn't!

Is there any way to test what speed the agp and pci is running at?

Sandra is full of baloney. The 1/5 divider was enabled with about the 1012 BIOS or so.

Thanx man
