I have an IWill VD133PRO motherboard with a 733EB P3 and PC133 SDRAM. I overclocked my processor to 913MHz (166*5.5). I had to turn the memory clock to hclk-33MHz, cuz it won't even boot if I leave it at hclk. My problem is, it says that my DRAM clk is at 100MHz during boot up. With my current setting, shouldn't it be 133? If not, how do I make my DRAM clk run at 133MHz?

Thanks for any help.

May have to break out the MB manual,... not familiar with that board, but I'd bet there is a a jumper somewhere that needs to be changed.

I do not know if that motherboard is 100mhz max or will even run 133
this is the most likley reason for the -33 requirement
one reason for the -33 may be keep you from overclocking your pci/(and agp bus if agp)
does your board/ bios have a 4/ divider? (100 mhz is /3---66= /2)
if it's AUTO then you'll really have to dig
use what works or dig through some older forum posts
what did SEARCH find on your motherboard
pc133 ram will run but most likley not at pc133
you might be able to tighten up your timings at 100 to cas 2 or some bios give you a choice between 8 and 10 ns, etc depends on your ram
Iwill usually has manuals online

however you are doing fine so far
7200 rpm drive will really help if you do not have one
