Chaintech VNF3-250

[fibes]

I installed 2 x 512MB 3200 doubled sided sticks in module slots 1 and 2. My internal system BUS frequency reads 333MHz when POSTing. How can I change it 400 MHz? Is it something I need to change in the BIOS or is it a jumper on the motherboard? I'm thinking it's a jumper on the motherboard, but I don't know which jumper it would be. There are so many, and the documentation that came with the motherboard is so piss poor. Can someone help me out?

Thnanks!

Its a platform limitation. Unless you have a winchester or later core, you can't run 4 double sided DIMMs at 200Mhz. If you do have a winchester or later, you can do 200Mhz at 2T, or 166Mhz at 1T. Whatever you do, use Memtest86+ to make sure its stable.

he's only running 2 dimms and the board only has 3 dimm slots anyway.

go into the bios, there is a setting in there i believe. i'd have to look, but i'm fairly sure i had to change mine as well.

I Have this Board and According to the Manual, Which I found very well written if you read it.

2 double sided Memory Modules should be used in slot 1 and 3. Not sure if it will fix your Speed problem but It may work better the way Chaintech recomends

Oh, I can't read then. For a single channel board, using a cpu with a core revision less than D (newcastle, clawhammer, everything except for the new semprons) and two double sided DIMMs will force you to clock the ram at 166Mhz to maintain stability.

wtf?

I guess that wasn't very clear. D was an internal revision. Newcastle and clawhammer processors were C revision. Everything that's built on a 90nm process is E revision, including the new socket 754 semprons.

i'm running 2 double sided dimms at 200mhz in my single channel board just fine with a clawhammer.

That's great, but those cores were only designed to run at 166Mhz with 4 banks of RAM. Mine will reach 184Mhz with 4 banks before it becomes unstable at default voltage (2.5).
