overclocking

Hi all,

I'm having some odd memory issues with my build. Here are my specs right now:

QDI Superb 4 motherboard
Intel Pentium 4 Northwood 2.4GHz (512KB L2, 533MHz FSB)
3x 256MB PC2100 DDR266 RAM
16MB NVIDIA TNT2 Pro AGP
Seagate 80GB IDE HDD
Generic USB 2.0 PCI
Generic Modem PCI
Bestec 250W PSU

To be even more specific, here are the current brands and models of each module:

Kingston KVR266X64C25/256
Samsung PC2100U-25331-Z
SMART SM5643285D4N0CHM0H

Supposedly, they are all PC2100 266MHz modules with a latency of 2.5. Looking in Speccy, the Kingston module is somehow running at a speed of PC2300 ~284MHz. I've never overclocked RAM at all as I don't know how to.

However, when I first started the computer, I had the SMART module in place first and then reset the BIOS settings, including the integrated overclocking options. However, this still doesn't explain why the Kingston module runs at a higher speed than the SMART and Samsung module.

Why is it like this? On a side note, where could I find the motherboard manual for the QDI Superb 4?

Thanks in advance.
