couple more OC'ing questions

[asdfguy]

Ok, does this sound right?

I must first find my max. mem. speed & max. cpu speed. I do this by lowering my cpu mult. and increasing my core untill my mem. test becomes unstable, in which case I up the mem. voltage and keep going. Once I've determined my max. mem. speed I set everything back to default. I then lower my ratio and attempt to find my cpu max. speed by upping my core speed once again. I do this untill it becomes unstable at which point I raise my cpu voltage and keep going. Also I know that I must keep my HTT around 1000Mhz.

My questions:

Why do I need to keep my HTT around 1000Mhz and what happens if it's above or below?

How do I know how much voltage is too much for my mem? I know that for my cpu I can determine this by watching my temps.

I use PCProbe, one of the items for temp. monitring is mobo. Which part of the mobo. is it monitoring?

Everytime I increase something, I should run a test to determine if it's stable. For how long? I've read I should run Memtest when testing my memory. But that runs for 16 hours. Do I really need to run a test for 16 hours every time I incease something by 5Mhz?

Thanks in advance!

The memory voltage should only be increased so that it's stable if the system isn't stable. The HTT speed shouldn't be over what is announced as max supported for the mobo, cause if it does it will become unstable. It can be a bit over, but not by a lot. And if it's too low the bandwidth to decrease, which will cause the performance to be a bit poor compared to if it's all properly set.

raise multi, raise vdimm, works great.

How about raising the frequency first? The voltages should only be played with last, and very carefully.

Watch for stability issues. You shouldn't be increasing the voltage much at all.

I think that it is the North bridge, but I am not sure

To test the CPU, just run SuperPI. I don't have much experience in OCing RAM, but I don't think that MemTest would do anything. Just see if your system is stable while running SuperPI.

When using SuperPI don't just OC until SuperPI reports about an error, you should always check the checksum at XtremeSystems. Cause sometimes it can calculate without errors, yet it won't give the right "answer" which could show up as errors when playing games etc.
