Another Northwood OC questions

[onza]

Well i finally purchased a northwood 1.6a and i have a few questions that i'd like to be answerd.

1. As you increase the FSB i notice that the pci bus also increases but at speeds of 100 and 133 its 33, which is what you want it to be at... so my question if its in the lower 40's what does it really do to the hardware ? the higher the fsb in pci = higher temps and more volts??

2. What does the CPU/MEM - 1:1 4:3 4:5 4:6 exactly mean?

3. added questions on memory timings, cas latency(2.5, 2), ras to cas delay(3,2,4 ), ras precharge time(3, 2, 4), and ras active time(6, 7, 5, 4).
the first vaules listed are the ones present... i'm just wondering what those numbers mean.

my setup is p4s533, ocz pc2100 memory, northwood 1.6a, asus gf3 v8200, and as of right now i have it at 133fsb..

onza~

1. the higher the pci the higher risk of damaging your pci cards and corrupting your harddrive.The temps shouldn't be affected and the voltages won't go up but the hardware is made to run 33Mhz and many cards and hd's crap out at about 40Mhz pci, pushing it above is risking killing something. The harddrive is also connected with the pci-bus and as the pci is increased there is a much higher risk of bad writes and thus corrupting the os and files written on it.

2. The speed of the memory is related to the fsb, 1:1 means the memory runs the same speed as the fsb (ie 133Mhz fsb = 133Mhz memory), 4:3 is the fsb at 133 and the memory at 100 (or similar with other numbers), 4:5 cpu 133 ram 166, 4:6 cpu 133 ram 200 etc.

3, it's the memory timings, the lower is better. Not all memory can run with low timings though.
