845G and DDR333 Question

[MacKenzieIII]

Ok, yesterday I got a 845G Motherboard.

And I had understood (from reading Toms Hardware) that these motherboards (unlike the 845Es) could do a FSB of 133 while doing DDR333.

But when I go to mine, I only have 2 options either 2x or 2.66. This means at fsb of 133 I get either run the DDR at 266 (2xFSB) or at 353 (2.66xFSB).

Now I must admit the motherboard I got was from the totaly new and untried Albatron PX845G Pro II. But I had though that the ability to do FSB 133 and DDR at 333 was common thru out all 845G motherboards. Is this wrong? Has anyone else had problems getting DDR333 at FSB133 with an 845G motherboard?

IIRC, for those mobos, above 132MHz FSB, you have to move a jumper, to enable the extra ratios. Not real sure though.

I second that, On my epox 845g i can set the fsb to 133 in the bios, but i dont get the 4:5 ratio for memory until i set the MB jumper to 133.

My motherboard has no jumpers So are we saying that maybe the board knows that my chip is really just a 100fsb (1.8A) chip. And since I cant trick it with a jumper, like the Epox board. It will not offer me the 2.50x option?

Since the 2.50x at 100fsb would be DDR250 and thats nonspec?

That seems really stupid. But I guess. I can use the Bios to turn the FSB to 133, with the Epox board does that work the same way the FSB133 jumper does?
