vista WON'T boot with 4gb
Peter,
I know Windows Vista doesn't use the whole 4GB. That isn't what I was saying. If you look at my original post, I did mention that. My point is that Windows Vista does report correctly that my PC does have 4GB of memory. My system has 4GB and Windows Vista is showing me that I have 4GB. From a hardware perspective, that is what I want to know. Now from a software perspective, you may want Windows Vista to tell you how much RAM is usable. I don't really care how much RAM Windows Vista uses when it comes to the operating system telling me how much physical RAM the system has. After all, it swaps stuff to the hard drive anyway. If I put 4GB of physical memory into a PC, I want the operating system say the PC has 4GB of memory. But my main point was to help anyone that has this same problem with their system when they attempt to upgrade from 2GB to 4GB. Before they start messing with voltages, they should try upgrading the BIOS which may solve the problem. After all, we are not all experts on what voltages all the hardware should run at. "Peter Foldes" wrote: Henry Here is a better explanation as copied from Ken Blake MS MVP You can't use the entire 4GB of address space. Even though you have a 4GB address space, you can only use *around* 3.1GB of RAM. That's because some of that space is used by hardware and is not available to the operating system and applications. The amount you can use varies, depending on what hardware you have installed, but can range from as little as 2GB to as much as 3.5GB. It's usually around 3.1GB. Note that the hardware is using the address *space*, not the actual RAM itself. The rest of the RAM goes unused because there is no address space to map it too. -- Peter Please Reply to Newsgroup for the benefit of others Requests for assistance by email can not and will not be acknowledged.

"Henry Morgan" Henry wrote in message ... I encountered the exact same problem with Windows Vista 32-bit. My PC has worked fine with 2GB of memory. I figured upgrading would be simple and purchase a new set of Corsair Dominator 2GB PC2-8500 C5 1066MHz modules (2 x 1GB DDR2). This pair is EXACTLY the same type as was originally in the PC. With 4GB installed, I would get the Blue Screen of death when attempting to boot. Even when trying to boot in safe mode. I tried some of the things suggested here and then decided to see if my motherboard had an updated BIOS available. Sure enough, my BIOS was a year old and one of the new versions reads "Improve Memory compatibility". I didn't think upgrading the BIOS would fix the problem since the original and new memory was working fine when installed separately. But to my surprise, it fixed the problem. I am now running Windows Vista 32-bit with 4GB memory installed and it reports that the system has 4.0 GB. Whether is uses all 4 GB, I don't care. I just wanted it to work. So the first thing I would check if you get this problem is your BIOS.

Thanks for your explanation Henry

I'd like it to show both the amount of physical RAM detected (good for troubleshooting a hardware problem) and also the amount available for use by the OS (helps with optimizing RAM usage) Tom Lake |

Install Aida32 or Everest
