Could use some pointers...overclocking

I think i'm ready to start testing the limits of my rig although i'm sure i'm going to be very limited by my slow memory timings and cpu lock. My system setup is as follows.

Gigabyte GA-K8NS Pro
ClawHammer 3200+
2x 512mb Kingston pc3200 valueram

First off my multiplier is locked at 10x so i'm limited in that area and then obviously my ram is an issue. One of the things i'd like to know are the maximum timings of my memory. Everest says @200mhz both modules are 3.0-3-3-8 cl-rcd-rp-ras. Does this mean these are it's maximum values? Should i even bother messing with the ram timings on this rig? Should i just stick with pushing the fsb? Also i guess i'm a little nervous about following standard guides and pushing the voltages with both the clawhammer & cheap memory.
It's been awhile since i did any overclocking beyond my videocard so i'm feeling like a neophyte all over again.
I'm hoping someone can get me started in the right direction here.

basically what you need to do is to lower the HTT multiplier to 3x or 4x and use a ram divider setting lower than 1:1. If you manually set you memory to 133, 150 or 166Mhz you can push the core speed without your memory limiting you.

Don't change your timings on your memory it's not really woth it.

I've been reading a little on the HTT but i don't understand it. Tried on both 3 & 4 with the same results so not sure which one to leave it on.
Should i lock the memory at 166 or should i just try to keep it at or below 200 as i increase the fsb?
Also now, for some reason uknown to me, i can't change the cpu multiplier like i could before. Before it wouldn't go beyond 10x but it would go below 10x and now it won't. (??) tried disabling spread spectrum and nothing.

Off to a bumpy start...

Now by setting the RAM to 166, you are not locking anything.
What you are doing is running the RAM @ a fraction (5/6 or 0.833 to be exact) of the speed to the HTT (akin to FSB).

I would suggest setting the LDT or HT multi to 4x (or 3x if you have your HTT over 250) to keep your HT frequency below 1000.

LDT x HTT = HT frequency (akin to system bus i guess you could say)
