DDR1 motherboard with DDR2 Graphics card

[psd99]

Hi guys,

Got a problem here.

I've got a Sony Vaio desktop PC which has a DDR 1 (2GB) of memory and I want to upgrade the graphics card.

I had a Nvidia FX 5600 128MB DDR1 Ram and I got a ATI Radeon HD2400 PRO 512 DDR2 RAM.

I had no problem with my old card it used to work fine on XP. But since I have tried my new card it keeps getting stuck on the BIOS. I noticed that the system halts on reading NVRAM. I then have to turn of off the PC manually and restart it.

Then again it goes into the BIOS I see it halting on NVRAM. Sometimes it will get into XP but it will freeze and totally lock up the PC.

I haven't seen this thing before does this mean that there is a compatibility problem as my 2GB of RAM is DDR1 and my new graphics card is DDR2?

Please let me know what you all think?

Hi the fan on the new card works fine.

I shall test the new card on another machine and see what happens that machine is also DDR1 memory.

What is the chances of the GFX being faulty if it does boot up but stops in the BIOS?
