winchester 3000+ running badly

[Highlandish]

In case Wes is asleep,

You'll find a hypertrasport ratio setting as 5x, 4x, 3x...

So, if your clock is the stock 200mhz and your ratio is the stock 5x,
you get a 1000mhz hypertransport bus.

But, when you start raising the clock it raises the bus, which
shouldn't go over 1000, so you reduce the ratio. At 4x, it will not
reach 1000 again until the clock is at 250. To go higher on the
clock, you'd go to 3x. Apparently the slower hypertransport doesn't
hurt performance.
I just did my 2nd cpu overclocking, on my A64 Winchester, and I feel
so clever! It's just at a clock of 245 with memory set to 133 and
hypertransport at 4x, pci and agp locked at 33 and 66.

So, the cpu, having a 10x multiplier (locked above that), is at 2450
and hypertransport is at 980, and the memory is at (245/200) x 133 =
163, and it's pc2700 memory meant for 166. So everything's ok. It ran
prime95 for 10 hours at 1.5 volts, but at the default volts it got
errors early on, in the first round.

I loaded AMD's cool'n'quiet driver and it said it was varying between
1.1 and 1.4 volts. But I know that if it ran hard at 1.4 volts it
wouldn't make it through a round of prime95, and it does. I tried
uninstalling the cool'n'quiet and tried prime95 at 1.4 volts, and it
got errors quickly. So I would say that the cool'n'quiet display
panel is wrong.
Nice to turn a 3200+ into a 3800+.

excellent, I should now be confident to go ahead. I must say previous
overclocks on different machines had been easier.

but once I am familiar with this setup it should be easier than the previous
ones.

next question, when you say lower the HT link to 3 or 4, do you mean
300 or 400mhz instead of the current 1000mhz?

I should have said 3x or 4x, but it reaaly depends on the bios as to how
you do this. You need to get the link down to either 600 or 800 depending
on how far you are going to overclock. I think Ed explained it pretty
good. It's just that some baords let you set it via a 3x, 4x, or 5x
multipler while others, like mine set to 400, 600, 800, etc. on mine for
3x I'd set it to 600 since that's how my bios does it, then if I raise the
system clock to 233Mhz, the HT link will go from 600 to 3x233 (700). you
can probably set yours to 800, and then when you raise the system bus to
266MHz the Ht data rate will only be overclocked to about 1066. Shouldn't
be a problem. If it is then set your initial rate to 600,

thanks, I'm looking into it.

I can't remember what motherboard you have -- it has to have a lockable pci
and agp so they don't go up with the clock. nforce 3 ultra (939) is what I
have.

mine is the A8V deluxe from asus. I'm tempted to use an old 6g drive with a
new install on it to see if it corrupts the data, if not I'll put this
original back in.

I'd guess that has a pci/agp lock. Just guessing.

Yes, you could do a clean install on the 6g drive and if it turns out real
nice you could use bootitng in demo mode from a floppy to copy it to the big
one. You could put the 6g in a slide-out tray and use it to back up stuff.

below is a cpu-z dump. it all seems normal and is running on an asus
a8v-deluxe rev1 with a new install of xp-pro, I have 1gig pc3200
(2x512).

its been solved, I had cool and quiet on while overclocking, this disabled
the setting to change the vcore. I set it to 1.550 and now my system is
beautiful and OC'ed from a 3000+ to a 3800+. that's a 33% OC of 600MHz!
