Hey all,
I was hoping someone could help me out with this.I may have posted it in
another group as well.
I have the Chaintech VNF3-250(BIOS 10/19/2004), A64 2800+ and 512MB
Buffalotech(winbond) PC3700 DDR.
I have the system running at 218 FSB(CAS 2.5,3,3,7,10) and it shows 1971 at
boot. But,the DDR shows 365mhz. When I first got the mobo/cpu the ram did
show 400mhz so I know it can do it. But the original BIOS was buggy as hell.
The last two BIOS versions won't give me 400. Any ideas?Thanks

Lower the base ram speed to 133MHz. Lower the HT link to x3 (or 600 if
your bios shows it to you that way). Raise vcore by .1v. And then raise
the FSB to somewhere between 233Mhz and 266MHz. At 266Mhz, your ram will
be running 200MHz (what you/they call 400, but it isn't). Your cpu will be
running about 2400MHz, and your HT link should be running about 200Mhz
(the default and what they call 800MHz). You might also need to raise ram
voltage to 2.6v to get it stable. That's what I needed with the same ram.
Now you will basically have a 3400+. Make sure the PCI lock is on, but it
should be by default, maybe.:-)

Download CPU-Z and see what it tells you about what's going on.

I had problems with a version of a BIOS update for my board and when I
contacted the Tech Support they tried to tell me there was a problem
with my memory; even told me to go out and purchase new memory. I got
angry with their response because I was of the opinion the were waaaaay,
waaaaay out in left field. Well, when the next BIOS update was
published I updated my BIOS and, lo and behold, everything worked
correctly - again. I did not replace my memory.

BIOS 1.0 lets you set the DDR speeds manually all the way up to DDR 400,
in later BIOS DDR400 setting is replaced with AUTO setting, sounds to me
the board just doesn't like your ram, go back to BIOS 1.0, or sell that
ram to Wes. ;p

I am using CPU-Z. With the first BIOS the ram was correctly id'ed. With the
last two,it says it's Melco PC2700-512.WTF is Melco? Anyway,it was running
at 400(200) with the first BIOS. It runs fine at 350+FSB ,CAS2.And,I'd
rather not use the origial BIOS.It was buggy as hell,though it looks like
this latest one might be too.
