Ram voltage cause of crash when OC'ed?

My specs:

Asus K8n-E deluxe
3400+ clawhammer
1 gig OCZ platinum rev. 2

Hello. When I set my FSB clock to 220 (20 higher than the default) my games instantly lock up and crash. I am assuming this is a ram issue.

1. Would my ram voltage fix this?

2. What should I have my ram voltage set to?

3. Is it possible to get a 220 FSB overclock (2.5 ghz) with my ram at 400 mhz with stability? If so, how would I do that?

Thank you.
 
The lock ups could be from the CPU itself or the rams. So to find out, you will need to buy faster rams first like PC4200 or higher. If the system becomes stable then the rams need to be replaced. If the system still locks up, then the CPU is the problem. In this case, you can try raising VCore voltage to see if it can get stable. Caution, this can actually destroy your CPU. Advise do more research before you jump to conclusion.
 
I would follow the "isolate then consolidate" advice. Set your ram divider to 166 or 133 and your HT link multiple to 3x or 4x, to take these both out of the equation. Then you can find the highest HTT (not FSB) base clock and CPU multiplier combo that the CPU can do with stability. Once you have that, then do the same thing for the ram and HT link, i.e. set the CPU multiplier low to take it out, and then work the ram multiple to edge it up as high as it will go. When you find the highest speed the ram and CPU will run at you can work out the math to figure which base clock and multiples get you closest without going over.

When OC'ing, it's not a good idea to just raise the FSB to some point and hope everything works. You need to start by doing as stated above. For more info, there is an excellent OC'ing sticky in the CPU forum that explains this in more detail.
 
My motherboard has no settings for HTT, it just has CPU clock multiplier 1-11 and FSB 200-300. I have a HT thing that goes up to 4...what should this be set to? I have no idea what this is. Also, my ram can be adjusted, but there's no HTT for the ram either. I'm confused. You're asking me to do things that I don't think are options in my motherboard's BIOS.
 
I just don't understand what HTT is, or where to find it. I've actually read that sticky before, it makes as little sense to me as what you're telling me to do does. I don't have a HTT setting, it's just not in my motherboard. I have a HT ratio, ram settings, CPU multipllier and FSB multipllier. That's it. No HTT.
