Does Vista 32 bit support 1066mhz ram?

Am I missing something here? I know that vista 32 will not support more than approx 3.25 gig ram, but does it not also support 1066?

I built a new computer, I knew that it was not going to support the full 4 gigs I purchased but I was not expecting to be stuck at 800 mhz.

Is this the case or is there another problem here?

POST shows 800 and loads windows fine.
I go to BIOS, manually set 533 and then it pasts post showing 1066 but then vista fails to load.

I have:

RAM

CPU

Motherboard

When POST runs it shows that it is running at DRAM clocking at 800 and not 1066. This is with the auto settings in the BIOS.

When I try to change the bios to 533, it will show 1066 in post but then it will not run in vista.

Set voltage & timings manually.

Memtest86+.

Then try getting into Windows, & if it's actually stable, you'll be able to.

Setting the fsb to 533 means you're trying to overclock your processor a lot.

Don't increase the fsb like that, instead go into the memory timings and set the divider so just the memory runs at a faster speed.

But note: this has practically no impact on system performance. Memory speed simply impacts bandwidth and the AMD chips are not bandwidth limited even at lower memory speeds (DDR2-800 provides plenty for them) so the extra speed is just a waste. Which is why most of us around here recommend against spending extra money on high-speed memory.

I have never had to manually set my ram speed before. I do not know the information on my hardware to compute the timings. Where can I find the information or can someone help me compute them?

Thanks.
