Help with 7VAXP!!!

[NIKO]

I Got some problems with my Gigabyte 7VAXP board, I can't get It to start with the FSB switch set too 166MHz.

On this page they had no problems with getting the board running with 166Mhz, they can set the FSB from 166 to 200MHz:

And on this page too:

What am I doing wrong.

The CPU is not unloked.
The cooler is a Vapoo.

What processor are you using, whats the Vcore, and what are your temps to start off with. You will need very good cooling in order to get any processor up to 166 fsb from the start.

 

[NIKO]

Processor: 2200+
Vcore: 1,98V (Max)
Start temp: -5°C

 

[cypher]

I wouldn't expect the 2200+ to run at 166 fsb even at -5C and 1.98V. These processors are known not to overclock very far especially when still locked. At that fsb you are going for a 446.7 mhz overclock very hard to obtain if not impossible. You would have more luck using an 1600+ or 1800+ to run at 166.

But should It not be able to bood op and then maby crash?

 

[cypher]

No running that high it wouldn't even POST. Try setting your FSB to something more reasonable like 135, than work up in 1 mhz increments untill you find where it will no longer boot. Than back off untill you get a stable boot and OS load. Finally run prime 95 for awhile to see if stable and watch your tempretures.

Thanks Cypher

Why dont you unlock the CPU and that way you will be able to lower the multiplier to 11x and set the FSB to 166MHz. If it wasnt stable at that you could set to 10.5x and then increase the FSB up from 166 and get the same speed as the 2200. The benefit of this would be that the CPU and the DDR would both be running at 333MHz and therefore you wouldnt have a bottleneck.
The 2200 is real easy to unlock, all you have to do is join the fifth(lowest) of the L3 bridges and that is all. See here for more info.

BTW I am presuming you have DDR333 or 400
