Hi. I have a P8H67 ASUS mother board. it has two PCI 16 Express slots. the first slot is Blue and second slot is black. When I put my 1 GIG DDR2 9500 GT graphic card in the first slot, it gives me 3 beeps and one long beep and no signal at boot, when I put the graphic card in 2nd slot, it works fine and nothing is wrong..when I check the black slot pins on motherboard, I saw it has less pins comparing to blue slot...what is happening? is something wrong with motherboard? why doesn't the blue slot work while the black works? Thanks Alireza

Here are the specs for the motherboard for the HP Pavilion a6700f -

• Manufacturer: ECS
  
• Form factor: microATX - 24.4 cm (9.6 inches) x 24.4 cm (9.6 inches)
  
• Chipset: NVIDIA GeForce 6150SE nForce 430
  
• Memory sockets: 4 x DDR2
  
• Front side bus speeds: 2000MT/s (2.0 GT/s)
  
• Processor socket: AM2+
  
• Expansion Slots:
  
  
  
  • 1 PCI Express x16 slot for graphics card
  
  
  • 2 PCI Express x1 slots
    
• 1 PCI slot
  

If you can find something similar you should be ok.
I can assist if you need someone to "review" any replacements you might be considering.

Asus P5NSLI mobo?

http://www.asus.com/Motherboards/Intel_Socket_775/P5NSLI/#specifications

Supposed to have two expansion slots for PCI Express graphics cards.

If the Blue one is used ONLY, it is PCI Express X16

When two -> SLI-Ready <- PCI Express cards are plugged into the Black PCI Express slot, and the Blue PCI Express slot; the Black PCI Express slot operates at x8.

PCI Express x8

The Blue PCI Express slot does also. PCI Express x8.

So you're stating that one of the PCI Express slots are gone?
Just solder blobs where it should be?
Reply in a Comment.

Both PCI Express expansion slots are gone?

There are still the white PCI expansion slots. Not ANYWHERE as good, but any of them can be used for a PCI graphics card.

You mean will the Asus ATI Radeon HD6450 with 1GB of graphics memory, work in a Compaq Presario SR2020NX Desktop PC?

Yes.

The Compaq Presario SR2020NX Desktop PC has a PCI-Express x16 expansion slot.

{Motherboard illustration and photo are towards the bottom of the page}

Look at the specifications.
Scroll down to the heading - Expansion slots.

Three PCI. (PCI expansion slots)

One PCI Express x16 graphics.

NOTE*
Looking at the motherboard illustration, it is Wrong.
Shows - PCIEX1 (PCI E X1)
According to the specifications it is a PCIEX16 expansion slot. (PCI-E x16)

A PCI-Express x1 slot has 36 contact pins. 18 on each side.

In comparison a PCI slot {White} has 124 contact pins. 62 on each side.

Looking at the photo of the supposed PCI-E x1 slot they show, the black PCI-Ex1 slot is longer than the white PCI slots.

It is a PCI-Express x16 slot with 164 pins. 82 on each side.



The Asus ATI Radeon HD6450 uses a PCI-Express x16 expansion slot.

So you know the graphics card will fit. Low-profile to boot.

Power requirement:
The Compaq Presario SR2020NX desktop computer comes with a 300 Watt power supply.
(Although in actuality it's more like 70 percent of the maximum rated wattage. 210 Watts)

Enough power for the computer, and the graphics card.
ATI graphics cards do not use as much power as a comparable Nvidia graphics card.

Concerned that the Asus graphics card uses DDR3 graphics ram memory, and the Presario SR2020NX uses DDR2 Sdram ram memory?

Don't be. The graphics cards graphics memory runs independent of the computer's ram memory.

Be sure to check which slots you are putting them in, stay within the same colors as to which needs to be put in.

This may be why, looks like your using DDR2
DDR2 1066MHz DIMMs work only on the black slots for one DIMM per channel. Ensure to install the DDR2 1066MHz DIMMs ONLY on the BLACK slots!

This may be the case for all speeds of DDR2

You ASUS mother board has 2 PCI slots.
1 PCI Express x16 <- this 1 is for video expansion
1 PCI Express x1

You can use any PCI express video card; preferably an ATI one so it doesn't conflict with your current ATI chipset.

Now a days every motherboard is come with PCI-Express Slot and this mothrboard can also handle more than 3.0Ghz CPU and it support DDR2 RAM which is faster than DDR1 RAM.

High FSB and high storage of DDR2 RAM will increase your computer performace.

DDR2 RAM FSB is depend on your motherboard choice. Because your motherboard should be able to support your RAM FSB rate.

PCI Express X 16.

P5LD2-VM Manual

See page 1-20

Hi rovin,
So you bought an XFX GeForce 256MB video card. You're board has 1 free AGP 8x video slot & 3 PCI (White opened slots).
You mention there is not slot for the new card. (What type of video card did you buy)? PCI-E, AGP or PCI?
The only slot you're board does not have is a PCI-Express.
Look in you're manual on page 1-7 for the location of the AGP video card slot.
If you bought the wrong card, exchange it for an AGP 8x or PCI.
The ASUS P5PE-VM uses a integrated Intel® 865G chipset with integrated Intel® Extreme Graphics 2 Technology, which uses you're system memory to function.
If you need a manual you can download it from Asus. Click on the link to open to the P5PE-VM download site.

I hope you find this helpful.
