graphic card dedicated video memory problem

Nvidia Geforce 3d vision kit
November 1, 2010 at 07:04:49
Specs: Windows Vista, AMD Athlon X2
hi,
i have an hp Pavilion and i upgraded my ram from 2GB to 4GB and also installed a new 1GB graphic card NVIDIA n9400GT. When i had installed it, it showed dedicated video memory as 1024 mb. but recently my games were lagging and so i checked the system settings on my NVIDIA control panel and it showed dedicated video memory as 128mb.
Can someone tell me what the problem is and how to fix it!

Dedicated video memory usually relates to integrated graphics. Did you disable the integrated in the BIOS before you installed the card? Are you running Vista 32-bit or 64-bit? See how much of that 4GB RAM is actually being recognized by Windows.

Post the model of your pavilion and the full model number of the new 9400GT card.

Normally when you install an add in graphics card it disables the on board chip. Did you connect the monitor to the new add in card?

If both the on board and the add in card are not running on the same bus then the on board may not have been disabled. That is why I asked for the model of your Pavilion.

It appears the add in card comes in both PCI and PCIe configurations.

PCIe is the preferable choice if your motherboard supports it.

If you have PCIe on board and bought a PCI based add in card then you need to boot into the BIOS (setup) screens and disable the on board chip, or at least reduce the shared RAM.

OK, your computer has a PCIe slot. However, you did not post the full model number and brand of the 9400GT.

I need that to determine if the bus type is PCI or PCIe.

I suspect it may be only PCI. If that is the case and you intend to keep that card then you need to follow the instructions I posted above which are "If you have PCIe on board and bought a PCI based add in card then you need to boot into the BIOS (setup) screens and disable the on board chip, or at least reduce the shared RAM".

you need to install the latest graphics drivers for the add in card.

If you are using an add in PCIe graphics card then you don't need to do anything.

Going back to your original post you stated you are reading the results of nvidia control panel. I am not familiar with that utility. That said, I suspect that all you are seeing is the specs on the on board graphics chip.

The term dedicated memory can be confusing. When memory is part of the graphics card, as it is with the 9400GT it is dedicated RAM. However, your on board graphics chip can allocate up to 129MB of system memory to the exclusive use of the graphics. That 128MB is said to be dedicated.

If you added system memory (RAM) at the same time as you installed the 9400GT you may have done something wrong.

When you boot the computer do the start up screens indicate you have 4GB of installed RAM running in dual channel?

You didn't answer my question about where the monitor is connected. Do you have the monitor connected to the 9400GT?

Go to Device Manager and see what is listed for display adapters. Post back the results.

Did you install the latest drivers for the 9400GT in Windows 7?

device manager display manager says NVIDIA GeForce 6150 nForce 430,
yes my 4 GB RAM is installed in dual channels..

The thing is when it was installed the decicated video memory was 1024 mb but now it shows 128mb. and that change is easily feltwhile playing games. as in earler i could max graphics in alost every game and play it but ow in the lowest of resolution settings games lag.

i have a windows vista.

You STILL haven't told me where you have the monitor cable connected. Is it connected to the add in card or to a port higher up on the motherboard.

From what you are saying it sounds like you don't have the 9400GT installed at all.

Device Manager lists ONLY the Geforce 6150? That is the on board graphics chip.

the reason why your games lag is because u bought a crappy v-card.
9400gt isnt a gaming v-card.
I think your 9400gt is TURBO CACHE means it steal ram as a video memory.

" now i dont know whether it is the add in card or no". Did you install the add in card? If so, how can you not know where it is?

The on board graphics port/s are up high, next to the USB, PS/2, network, speaker connections, etc.

I am still not sure if you are even using the 9400GT. Lets assume you are. If the computer was given to you with the card installed then you have nothing to compare to. I thought you were comparing the 9400GT to the on board video.

Go to the link below and use option #2 to automatically download the correct drivers for that card. That may help somewhat.
