i know this is going to sound weird but it was the bracket on the raid card that was the issue. i swapped the ram around on the cards and it didn't work. i swapped the pcie slot and it worked with the 1 gb nv but not the 512. and when I screwed in the bracket it didn't work. so I unscrewed it and it worked. i did that a few more times and I came to the conclusion the bracket is magic
So I know it is odd but I have a perc h700 raid card with 512 MB of cache on a dell precision t7600. I acquired a perc h700 card with 1 GB of cache memory. I thought since its the same thing just a different cache it would work. well I unplug one card and plug in the other and the fans blast and nothing else happen, I didn't let it run for long because of the noise but it didn't respond to me pressing the power button and it didn't boot to bios. my question is what am I going to do. do I need to install firmware or something? I have no idea and I want to know if the card is defective. my guess is since I ordered it from eBay someone just found the ram and replaced the 512 MB ram with what they found. I did a similar thing with the other card and it did the same thing fans blasting and all. theirs a cable connector on the ram I'm wondering if I have to load something into the ram to make it work like some firmware but honestly, I have no idea. is my only option a return?
