Where did he say anything about having RAM with UTT-BH chips? BH-5 wont run CAS 3.

its not the chips themselfs, its the Eprom that has the timings and stuff.

The Eprom stores the timings and settings but its dependent upon the memory chips themselves as to what settings they are capable of running. BH style memory doesn't like anything but CAS 2. If you try CAS 2.5 and especially CAS 3 you'll just get errors.

Yep thats how you tell the difference between the Value VX BH and CH, it if will boot at CAS 2.5 then its CH. The Value VX I got was CH and wouldnt exceed 230Mhz no matter what the voltage/ setting.

BH will run 2-2-2-5 at 2.8V or less. CH wont.
Greenman100, you want to spend that extra $30 for decent memory because value RAM isn't properly speed binned. Unbinned UTT is often garbage, and quite unpredictable. The odds are not great - we're talking about a memory IC that is tested to ABSOLUTELY NO standard of operation or integrity after fabrication (Hence the name, UnTesTed). As such, UTT ICs in value RAM specified for CAS 2.5/3 operation are quite unlikely to overclock particularly well - they haven't been binned to see if the ICs are:
~ Capable of overclocking past spec (200 MHz)
~ Capable of running with tight timings
~ Capable of taking high voltages
A poorly manufactured IC that would have made it into the trash can had their been a standard of integrity/operation at fabrication (which there isn't for UTT) has a potential for sudden death at higher voltages - it hasn't been tested to any standard of integrity, and hasn't been speed binned aggressively by a memory module manufacturer.
225 MHz 2-2-2 at 3.3V doesn't sound like a lot, but may well be unachieveable with unbinned UTT.
