Check the power requirements of the new video card. Is your power supply adequate?
How old is it? It should say its rating and brand/model on the side.
The new video card may run with 1 stick of RAM, but 2 sticks could be overloading the supply.
If the video card box says it needs 400W and you have a 2-year old 400W
power supply, it may be too weak since power supplies get weaker over time.
See if you can borrow a friend's powersupply that is well above
the minimum requirements. If you need a new power supply, buy a name brand as they
are more reliable - get one that is 100W more than
the video card says it needs. (Some brands: OCZ, Corsair, Coolermaster, etc.)
And, make sure that the necessary power connectors for the video card are connected to the
Thank you for your reply. It operates with 2 sticks of ram but only in the B channel and only in single channel mode. I have changed the power supply 3 times thinking the same thing. The card recommends a 300W power supply, I have an ANTEC 400W supply. I even removed all but one of my cooling fans with no change, thinking they might be drawing too much power, I have 3 cooling fans plus the CPU fan. If it is a power problem, it is a very strange one. I pdut the exact same 2 DDR memory modules in Slot 0 of Channel A and Slot 0 of Channel B and the PC will not even boot up. I can put those same exact 2 DDR modules into the Slot 0 and Slot 1 of Channel B and it works just fine. Problem is that this is a very in-effecient way to use memory and it slows my system down. Not to mention with only the 1G of memory it doesn't work as efficiently as with the 2G I originally had in it. Since power supplies are not all that expensive I guess I could get a 500W supply and give it a try. It just seems strange that, if it is a power problem, it would not work with the two memory modules no matter where they are placed.
Again, thank you for you help
Manually setting the speed (timings) of the RAM in the BIOS - often AUTO can screw things up. Set voltage to specification 2.6 up to 2.8
Try RAM in diffferent slots:
Channel a slot 0 with B slot 0 or 1 or 2
Then swap the modules, putting the b012 into a0
and moving it around to b, 0 1 or 2 again.
The most recent BIOS release notes indicate that there has been a fix
for using large amounts of RAM. Perhaps you want to consider flashing the BIOS
if your version is not the most recent.
I will check the BIOS, I had downloaded what I thought was the latest from the Intel site but now am wondering about that. Regarding swapping the memory modules, I did that for every configuration possible for a long time and the only configuration where I would even get the 1G of memory to work is in single channel using channel B to hold both modules. However, I am going to put in a larger power supply and flash the BIOS again. Between the two of those surely that will take care of the problem.
Thank you again
