Hey guys I was thinking it might be nice to have a definitions bank in the OC guide. I get a little lost in the BIOS. Maybe its cause I have a newer Motherboard/bios but I have alot of options that arent covered in any guide Ive come across. Let me know if there is a another topic for this stuff.
Help with the definitions and how/why to adjust them would be great thanks.
On my bios OC profile under "manual" configure:

Besides the FSB freq. I have a PCIE Freq. (100-200) --
Adjust PCIE Frequency : Usually, PCI Express bus clock has no direct relationship with overclocking; nevertheless, fine tune will help overclocking as well.（The default value is 100, it is not recommended to set to 120 above, which might damage the graphic card.）

CPU Mult:
The clock multiplier (or CPU multiplier or bus/core ratio) is the ratio of CPU clock rate to front side bus or northbridge clock speed. A system with a CPU multiplier of 10x will have its CPU execute 10 complete cycles for every cycle of its FSB.


CPU Volt
CPU Voltage : This item plays a critical role in overclocking, but due to the relationship is complicated, which is not easy to find the best setting. We suggest users fine tune this value patiently, for processors might crash due to wrong setting. According to our experience, with a good CPU fan, the CPU voltage doesn’t need to set to the limit. Take Intel Core 2 Duo E6850 processor as example, it is recommended to set the voltage between 1.45~1.5V.

options are: Auto or Advance 900ps, 750ps,600ps---> 150ps, or normal, Delay 150ps
"AI Clock Skew is used to compensate for the differing lengths of the traces (wiring) on the motherboard between the memory slots and the CPU socket.
Note that one memory bank is further away from the CPU socket than the other. This results in slight differences in the time it takes for the CPU socket to communicate with the two memory banks.
If data from one bank arrives at the memory controller before it's corresponding data from the other bank (dual channel, remember?) then the memory controller must hold (cache for 1 clock tick) the first data until the second arrives.
AI Clock Skew can compenstae for these differences. It can save a clock tick every now and then. This probably won't speed up gane play, but if overclocked to the extreme, may add some stability.
It's interesting to note that the settings are in trillionths of a second."



IN my Memory options section

Memclock mode: Auto, Manual, Limit
Auto would fix it with the FSB Freq. I am assuming
CAS Latency: Auto, 30--->60
TRCD:
TRP:
TRAS: 5CLK ---> 12CLK
IT/2T Mem timing:
MCT Timing mode:
BANK Interleaving:
Sets whether to allow memory accesses to be spread out over banks on the same node or across nodes, decreasing access contention

NODE Interleaving:
Sets whether to allow memory accesses to be spread out over nodes on the same node or across nodes, decreassing acecess contention

DQS Signal Training control:
MemCLK Tristate c3/ALTVID
CS Sparing enabled:
DIMM Power Down Control:
Allows DIMMS to enter power down state by deasserting the clock enable signal when DIMMS are not in use

While a local guide would ceratinly not be unwelcome...
