DDR3

Dear all.

I have a PC with intel core i7 CPU, 6 GB DDR3 RAM.
It is already equipped with Gigabyte NVIDIA GTX 295, 1796 MB DDR3.
I need multiple monitors, so I added a second card, the Biostar NVIDIA GT 220, 1GB DDR5.
Unfortunately, the computer hung.
My friend said that the DDR5 on the GT 220 is not compatible with the DDR3 on the GTX 295, and also the CPU.

So, do I have to buy the DDR3 version of GT 220/240 instead ?

Thanks.

Doesn't multiple monitor support disappear when running in SLI?

It is impossible to run a GT220/240 in SLI with the GTX 295. He is not talking about using SLI, just putting a card in the second slot so he can use more than 2 monitors.
To answer the question, no, using a card with DDR5 shouldn't be a problem as the cards are working independently.
What version of the GTX 295 do you have? If it has 2 DVI outputs and one HDMI then it supports 3 monitors on its own;

Yes, I'm not running them using SLI.
I'm connecting it to 4 monitors.
Two monitors from the GTX 295 (the DVI outputs, leave out the HDMI output),
and the other two monitors from the GT 240 (1 DVI, 1 HDMI).

If you are wondering why, I'm using it for my computational research.
The GTX 295 has 2 devices. The first one is for visualisation,
while the second device is for running CUDA.
I add the GT 240 for additional visualisation (grid 2x2 monitors).

jyjjy, you said DDR5 would not be a problem.
So, do the vendors matter ?
The GTX 295 is a Gateway, while the GT 220 is a Biostar.

By the way, I just tried a Digital Alliance GTS 250, 1GB DDR3 as the second GPU.
o SLI of course. They worked.

No, the different brand shouldn't matter either. Honestly I'm not sure why it doesn't work. Have you gotten it to work at all? It could be as simple as a bad card.

I'm not sure too.
The biostar card works alone on the other computer, so it is not a bad card.
For the dual cards system, I'm pairing the GTX-295 and GTS-250.

Thank you for your answer.
