Is it correct for me to think that most of the problems caused by BCLK OC/UC are caused by the changing of the PCIe frequencies and not the BCLK frequency itself? (i.e. will i be able to OC via BCLK without a problem if it is separately controlled from the PCIe frequencies?)

If you are talking about current or recent intel mobos, I think just about everything is tied to bclk(sata, usb, etc). That's why if you go much past normal frequency you start running into problems(someone please correct me if I'm wrong with a link or 2).

I have a MoBo that has seprate BCLCK and PCIe freq controls, that's why i'm asking.

If your base clock is 133, I'm guessing you have something like an older model i7/i5/i3 (pre sandy bridge). If that's the case, you should be ok adjust the base clock up or down without affecting other systems on the mobo(other than ram). So you want to OC by raising the base clock, but you want to lower the base clock because you are getting dangerous temps at load. What cpu cooler do you have? You may need to reseat the cooler and apply new thermal interface material. Any change to your overall case cooling(new gpu, change in case fans, etc)? Are you getting really high temps on your mobo, or is it the cpu? Just wondering...

Rather than drop the base clock just drop your multiplier, this will decrease your frequency and your load. Down clocking this way would have the added bonus of not messing with any other clock speeds

CPU cooler is (probably) stock :( and underclocking is only a temporary measure until I can get my dad to buy a new one, the GPU temps are fine (below 80 deg C max load anyway)
And I only recently noticed the temps because I just installed a monitor for temps.
I really don't know the mobo temps.
