Asus A7V133

[Guest]

I've got a pair of these boards along with two 850 Tbirds to run on them. Here is my experience:

I have closed the L1 bridges. I am running the multiplier at 9.5. Operating continuously for 3 days with no problems. CPU is running at 49 C and mobo at 32 C - higher than I hoped, but well within operating range. I can't seem to get beyond 950 mHz.

I can't change the voltage from the 1.75 which is coded using the other bridges. Setting a higher voltage using the BIOS results in a hang and reset on the next power-up.

I can change the FSB rate, altering the PCI and AGP rates as well. According to the manual, going over 120 mHz will set the PCI divider to 4 instead of 3. Armed with that, I set 134 mHz and a multiplier of 7.5 (CPU at 1005 mHz.) It did not work, although I had upped the voltage, which may have accounted for that.

Questions: How do I change the voltage? I'd like to set 1.85 V. Is the divider for AGP based on PCI? I want to get as much as possible without squeezing the PCI and AGP specs too much. Anything else I missed?

Sounds like you've got a crossed/open bridge somewhere. You might try using a 'sharp' #2 (or even #1) pencil and a magnifying lens.
The agp is locked at 2/3 the system bus speed, I think. That puts it to 33/88 at 100/133 bus speed. If you aren't getting at least 1ghz on those chips, there's some thermal efficiency you're missing out on.

Are you using the bios to check your cpu temp?

I'm positive I got the L1 bridges right. I examined them through a high power lens. Besides, without L1 bridges closed, the clock multiplier cannot be changed in the BIOS.

According to the A7V133 manual, running the base clock over 120 mHz sets the PCI divider to 4. Whether a similar divider is used for the AGP clock I cannot say. I don't wish to run AGP that far over spec, but since it doesn't work anyway, who cares?

Temp is reported by the BIOS and read by ASUS Probe as well. I'm using the GlobalWin FOP 32 from Tom's cooler test and I expected it to work better. 46 C isn't bad, but it's higher than I expected it to be.

Isn't the voltage controlled by the L6 bridges??

According to what I read on AMD's site, it's controlled by the L7 bridges. However, I thought that closing the L1 bridges gave you access to changing the settings using the BIOS. I did not attempt to change the L7 bridge settings.
