The memory's 400mhz. No wait, 333mhz. Wait, 400...

Has anyone experienced this?

I recently put together a new rig with an ASUS A8N-SLI Deluxe (a very common board: http://www.newegg.com/Product/Product.asp?Item=N82E16813131517) nVidia 7800GTX and 2 sticks of OCZ DDR400 PC 3200 RAM (http://www.newegg.com/Product/Product.asp?Item=N82E16820146969). The initial build and install went smooth.

I upgraded the BIOS, and all of a sudden the board was "auto-detecting" the memory as 333mhz. I did a few reboots just to make sure it wasn't a glitch, then manually set the memory to 400mhz. Worked fine. I was disturbed to see it "auto-detecting" the wrong speed, so I turned auto-detection back on to see what it thought now. 400 mhz. What the heck?

I found that everytime I flashed the BIOS (to no matter what version) it would always "auto-detect" the wrong speed. Set the speed manually then change it back to auto-detect: voila, the correct speed always appears.

Is this a flaw of the board, a flaw of the sticks, or am I otherwise going crazy?

Nah it's common for that to happen.

Just set it back to DDR400 & be happy.

It's common for a board to "autodetect" the wrong speed? That sucks.

 

[The Pentium Guy]

It's common? Ah well, just set it manually then.

 

[n7]

Okay maybe not common.

But not terribly uncommon for A64s either AFAIK.

My 4x512 MB PC3200 sets itself @ DDR333 on auto, though that likely could be the result of using the 4 dimms.

 

[The Pentium Guy]

Yeah, that's the result of 4 dimms . THAT's a common issue.

I have a Venice. It should default to DDR400 @ 2T, no?

The older cores would default to DDR333, i know, but i AFAIK, it shouldn't with the Venice...

Yeah, it probably just excpects to force DDR333, so that is what it sets it to...

So manually set 400mhz? Is it going to hurt the board/sticks? I always get a little wary going against what the board detects.

 

[Cheezeit]

no, manually will not hurt anything

Solution: I actually read the instructions and put the sticks in separate memory channels like I was supposed to (instead of side by side). If anyone runs into this, don't be *cough* an idiot like myself.
