ASUS P5K-E and Graphics card problem

I have been using an Nvidia PCI-E graphics card with my P5K- board. I
upgraded to a new graphics card (GIGABYTE GV-RX385512H HD3850 RT), but
I can't get it to post. I tried both PCI-Ex16 slots. I tried the same
card in another system and it posted fine. When I put the old graphcis
card back in, everything works.

Any ideas?

maybe you need to change something in the bios "graphic adapter" as boot
device.

Does the new video card draw more current? If there is a power
connector that should go to the video card, make sure it's plugged in.
Does the power supply provide enough current on the voltage rail the
card uses (+12V? Not sure on the newer ones)?

It does. I bought a new power supply to provide the following:

24 pin motherboard connector
8 pin CPU connector
6 pin PCI-E connector

Still no response from the card. I tried it in another system, with
the same power connections, and it did post, so this is specific to
this system.

What are the specs of the new PSU? I.E. amps on each rail,
manufacturer.

Since you can run the system with the old card and the new card on
another system, The difference is the power supply, or the card socket.

BTW, is the 4x4 PSU plug installed in its socket near the CPU?

The PSU is a Rosewill RD500-2SB, it supplies 15A on the first 12V rail
and 16A on the second 12V rail, should be plenty. Its 3.3 V rail
supplies 22A and its 5V rail supplies 16A. Maximum power output is
480W. The motherboard has only one 8 pin plug next to the CPU, and
that's where the 8pin plug from the PSU goes. Could this card be
drawing so much power, I need a more powerful PSU?

The problem with power supplies is some manufacturers and/or resellers
don't always tell the truth about the wattage rating. The only way
around this problem is to get a PSU from a known good PSU
manufacturer/supplier.

From reading reviews from customers at Newegg, you can get an idea of
which brands are good. Seasonic is one of the good brands and some of
Antec PSUs are made by Seasonic for them. I have a Antec Earthwatts 430
watt PSU.

Your 480 watt PSU specs:
+5V = 16 amps
+3.3V = 22 amps
+12V rail 1 = 15A
+12V rail 2 = 16A

My Antec 430 watt PSU specs:
+5V = 20 amps
+3.3V = 20 amps
+12V rail 1 = 17 amps
+12V rail 2 = 17 amps

My 430 watt PSU outputs more than the 480 watt PSU you have. A perfect
example of the problem in buying a good PSU.

There is (and should be listed on yours) a maximum wattage spec for
specific rails. On my PSU, +5v and +3.3V rails combined can't exceed
130 watts. The two +12V rails can't exceed 360 watts.

The specs for the video card are:
450 (real) watt or greater PSU with 75 watt 6-pin PCIe power connector.
Certified power supplies are recommended.

In short, the PSU you have does not supply the current needed for
running that video card and the rest of the system. A "certified PSU",
I believe, means SLI certified, but it could just mean high quality,
high output.

A good quality (more expensive, but you get what you pay for), 500 watt
minimum PSU should be in your system.

Something like this is what I would consider. It has three +12V rails @
18 amps each, and 24 amps on both +5V and +3.3V. It has over 80%
efficiency (meaning more current is supplied with less heat; 80% of the
120V AC input is converted to usable power).

A very similar, specs wise, Seasonic PSU:
http://www.newegg.com/Product/Produc...82E16817151029

So look around, do some checking to see what you can come up with at a
price you can afford, but make sure it's a high quality PSU. Newegg is
a good place to look since you can get a feel for the quality of the PSU
from customer reviews.

The HD3850 is 63.1W in 3D mode, and less than that when you first try
to start the system (according to Xbitlabs power measurements). So
5 amps or so max for the video card, is not a lot of 12V load. You can see
the numbers here, that starting at the BIOS level draws very little power.
The 63 watt number only applies if something like 3DMark was running.

http://www.xbitlabs.com/images/video...power_full.gif

The HD3850 is PCI Express 2.0 standard. Only a few motherboards
operate PCI Express 2.0 interfaces. The rest use the older,
original PCI Express standard interface. What is supposed to happen,
is the video card is supposed to negotiate the connection rate,
and fall back to the 1.0 standard.

According to this article, ATI's solution to compatibility, is
to have the video card *start* in PCI Express 1.0 mode, and only
advance to 2.0 mode later.

http://www.xbitlabs.com/news/chipset...press_2_0.html

So that doesn't explain why the card doesn't work.

Does the motherboard BIOS beep the "bad video" beep pattern
to the computer case speaker, when the HD3850 is used ? Do
you get the single beep meaning "POSTed OK" ?

Have you tried connecting a monitor to either of the display
interface connectors ?

Is the HD3850 PCI Express 2x3 power connector connected ?

Does it look like the video card is mechanically seated properly
in the PCI Express slot connector ?

Have you tried any alternative hardware configs ?

1) Reduce system memory to only one stick of RAM. Install HD3850 and test.
2) Reduce system memory to only one stick of RAM. Install old
PCI Express video card, in the primary "blue" slot. Install
the HD3850 in the secondary PCI Express x16 slot (x4 wiring).
While there is no guarantee the HD3850 will be happy with x4
lane wiring, running that way may allow you to get into Windows
with the Primary card, and use utilities like Everest, to see
if the second card is visible on the bus or not. You may need a PCI Express
power adapter, to get a 2x3 connector for the second card, and at the
low power draw of the HD3850, even a single Molex disk drive to
PCI Express 2x3 adapter cable would be a workable solution.

I used another PSU (CLIO 550W, with the same results). In any case, as
you point out, the Rosewill PSU should have had enough power to deal
with this card (less than 35W at startup). Yes, I did try both DVI
connectors, and I did check to make sure it was seated properly. Both
power supplies have dedicated 2x3 PCI-E power connectors, and I'm
using those They both have two of those). Your email got me thinking
about one thing I have not tried yet: force startup in PCI 1 mode in
the BIOS, and see if that works.
