Are you exceeding the capabilities of your monitor ? For example,
setting the refresh rate to 150Hz or something ?

Does it look like a monitor type problem, or a video card type
problem ?

For the test that fails, what is the error message ?

If you run a game or attempt to use 3DMark, are there
any other error messages ?

If you cannot figure it out, send the card back and have
your vendor test it. Better than being stuck with a card
you aren't sure about.

had same problems, and with direct sound. I reinstalled DirectX 9.0b and
solved the issue.

No, I have an LCD connected with DVI, it was automatically set to the
optimal setting of 1280x1024 60Hz. I knew that it could also be set at 75Hz,
according to the LCD instructions, but the video card panel claimed that
only 70Hz was also available, so I didn't change it at first. But today, I
thought 70Hz is still within spec, so I tried it and now the tests pass. I
then changed it to 75Hz, because that is what it is suppossed to be.

But, the screen is still getting cut off, sometimes when I reboot. The BIOS
and Windows loading screens look to be correct, but its difficult to tell.
However, the Windows welcome screen has horizontal lines that appear to be
equidistant from the top and bottom; so if it is only once I get to the
desktop, if must be a driver issue, correct? Is this most likely a DX issue?
Any advice?

I tried DX 9.0c and Viewsonic Unsigned Monitor INFs and no combination
works.

Here is what I did notice, the BIOS menus and loading screen look fine, it
is the Windows loading screen where the screen gets slightly cut off at the
bottom and ghosted at the top. After a driver change and reboot, the screen
is always corrected, it is one, or at most two, reboots later that the
problem occurs again.

Also, I looked into my LCD's menu. When I select 'Auto Image Adjust' it
doesn't do anything, that tells me that the video card is sending a correct
screen, and the LCD doesn't see its own fault and doesn't adjust it.

Also, when I change the LCD's input mode from Digital to Analog, seeing as
there is no Analog connection, the screen goes blank and then switches back
to a corrected Digital Screen. The LCD re-initializing the input is
correcting it.

I will have to power off the PC and try the Analog input tommorow, my guess
is that it will work, but if it doesn't, does anyone else have a clue?

Thanks,

It appears as thought I have solved the problem; I turned off 'fast writes'
in the Radeon settings, and so far it has rebooted four times and the
desktop is fine, previously it was a maximum of two times. I read a thread
in the ATI NG from two days ago, and it seems it doesn't worsen video, but
can cure problems turning it off; what does 'fast writes' do anyway?

From the AGP20 spec (no longer available from Intel, because they
are idiots...) -

"The other enhancement to the PCI protocol is the acceleration
of memory write transactions from the corelogic to the A.G.P.
master device acting like a PCI target. This is called fast
write (FW). When the FW protocol is enabled, the PCI write data
target at the A.G.P. master transfers at the same rate as the
A.G.P. data transfers. PCI memory write targeted at the corelogic
from the A.G.P. master transfers at the PCI data rate. FW flow
control is more like A.G.P. than PCI. See Section 3.5.2.2.2 for
details."

The AGP slot uses a combination of protocols. There are transfers
via AGP protocol, at up to 8X. There are transfers that use PCI
like protocols at 66MHz. I think what they are saying above, is
when FW is enabled, the data burst gets sent on the bus at 8X
instead of the normal 1X rate. it is like DDR memory, in the sense
that DDR transfers two data chunks per clock, whereas in this case
the FW PCI protocol can transfer eight chunks in one clock.

Now, on the surface of it, that suggests a huge speedup. To
really understand what happens, you would need to know how large
the typical FW PCI transaction is - it is quite likely pretty
short, so there might not be that much performance gained with
the protocol enabled. If you run 3DMark, you can bench this
for yourself, and tell us how much difference it makes
