Hello know-hows,

Can any of you nerds tell me if the following are compatible please?:

Intel D975XBX motherboard
Corsair TWIN2X2048-6400C4 2x1GB 240-Pin DIMM XMS2-6400 CL4

Motherboard manual states it supports 533/667mhz whilst these modules are 800mhz.

I'm new to this and about to build my first PC. If anyone can help me with a few questions I'd be grateful.

Thanks in advance...

lol...

I have that board and that memory... It works fine on that board and I was able to overclock mine well above 1GHz from the factory 800MHz clock speeds. The limiting factor on that board is the voltage as it only goes up to 2.2 Volts.

Thanks for the quick reply.

Your obviously a man with excellent taste!

Did you have to tweak the Bios? Or does it configure automatically?

And why does the 2.2voltz limit you?

Is that too many questions?

Whas that another one?

And why does the 2.2voltz limit you?

2.2V is limiting because the Corsair PC2-6400C3 and C4 memory series can handle more voltage than 2.2V.

As you noted 800MHz is not officially supported, so you have to manually set it.

From your brief answer I gather it's quite a complicated procedure, but I'll ask anyway:

How does one set the bios to overclock?

It's OK, I'm not going to overclock it as I've read that long term it will damage the processor.

I read the D975XBX manual and it says that when installing memory, remove any device in primary PCIE.

As I'm building from scratch, and my graphics is PCI express, and I need the graphics card plugged in to see the boot, I'm presuming I use the secondary slot?

But when can I return the graphics card to the Primary? or do I not need to?

I believe it's a physical problem in that the video card in the primary PCI-E slot interfere with inserting/removing RAM. No need to move it anywhere else, just install your RAM first. ;)

In case you're wondering, I have this board and it's nearly impossible to do anything with the RAM while the video card is in.

thread locked as you have more than one open with the same question.
