Does Vista 32 bit support 1066mhz ram?

[imported_Giuseppe]

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.

Your overclocks failed.
Therefore Windows failed to load.

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.

It's all there on the Newegg specs page.
