I was at the edison computer show yesterday, and while I was just going to pick up a 8500, I ended up getting way too much stuff for the second box- and having put it together I have a question.
I picked up a ECS P4VMM2 motherboard for a Steal, I also picked up another P4 1.6a (I really like how quiet they are)
here is my question.
I am trying to get the system to work at different frequencies. I know the ECS are not very overclocking friendly, and the P4VMM2 has almost no documentation online.
The bios lists sdram dimm settings at 100 or 133 frequencies, the cpu jumper on the motherboard can be set at 100 or 133, the ddr setting can be set at 100 or 133 (effective 266 freq)
I am using some crucial 133 sdram (222) that I was previously using on a a KT7 without problems-
If I post with the cpu freq set at 100, the sdram at 133 it will start up normally, resulting in cpu at 1600, and ram at 400 freq (ram freq at 100 Mhz) EVEN though the setting in the bios is for 133 Mhz
The board will not post if cpu freq is set (by jumper) at 133, I assume that it is because the cpu is Locked. (the bios will list the cpu and will not allow changes to it)
interesting fact- if I set the cpu jumper to open (neither the 100 or 133 setting) the computer will boot at 100 (again I think because the cpu's frequency is locked)
Why would the bios let me set the sdram freq at 133 at cas 2 if when the system loads, sandra states it is running at only 100 mhz?
why would the motherboard have a cpu frequency jumper (100 or 133) if the cpu is locked and will only allow it to run at 100 mhz?
would pulling the ddr stick off my primary machine (now with ati 8500
) allow the setting of the cpu frequency or would it just allow the setting of 133 for the ram in the bios (for 266 ddr) I am really impressed with this motherboard none the less, for 65 bucks allowing me to have onboard video, Lan and sound. (although it is now hosing the radeon LE)
