About 2 week ago I was playing and enjoying Hellgate: London, despite the so-so
reviews. It is simplistic, but fun. Anyway, my system is about a year old, I custom built it with a fast dual core CPU and a high-end graphic card. I went with the 64bit version of Vista because I was expecting to upgrade over time and I was hoping games would start taking advantage of the processors. The system was setup with 2 gigs of ram, which i figured would be enough for a while. However, as I played the game I was encountering severe slowdown. Looking at the system monitor I found that Vista was taking close to a gig of the ram and the game was easily taking the rest.
Shopping around a bit I found a great deal on another 2 gigs of ram from the same family as the original set.
2 gigs of Cosair 800mhz DDR2. , $87 ($47 after Mail-in rebate).
A few days later the ram arrived and I popped it in expecting the system to be humming in no time. Instead I was hitting long Vista startups, followed by a crash a few minutes into the startup completing, if it got that far.
My first thought was bad RAM, so I ran the new Memory diagnostic included in Vista, but it didn't find any issues. Than I pulled the ram and hit google to track down the issue.
Turns out I have a problem with the motherboard and Vista that took a good deal to track down and set up, but now that it is done, everything is running smooth at 4 gigs. If you are running into a similiar issue, I hope this helps.
First off, if you are going to 4 gigs or beyond, you should use a 64x processor and version of Vista. You can get up to 4 gigs of RAM with XP and Vista x32, but it takes some tweaks and it doesn't fully use all 4 gigs. See Pae for details. I have an ASUS P5N32-SLI SE Deluxe motherboard. The Microsoft KB doesn't specify this motherboard in the description, so I assume it is true of other motherboards as well.
Here are the steps you need to take if you run into the same issue.
- Take out the new ram until you are done.
- Read the manual, or at least skimp it for pretty pictures and anything to do with Bios updates and Ram.
- Update the Bios. If your motherboard supports it like the P5N32-SLI than use EZ-Flash. Get the latest ROM from the motherboard manufacture website and write it to a floppy. Rename the file to P5N32SD2.ROM. When the system is loading hit <ALT>-<F2> during the POST to get to a EZ-Flash prompt. Then insert the diskette with the latest ROM.
- Once it is flash load up windows and make sure you are still good.
- Get the KB file KB 929777. Install the KB and reboot.
- After the reboot, check to make sure everything else is patched up to the current level and shutdown.
- Once it is down, install the new ram and boot it up, stopping at the BIOS setup, which is usually <DEL> during the POST.
- Here comes the painful pain that I am going to research further to figure out why it is necessary. In order to get the system stable at 4gigs I had to knock the memory speed down to 600mhz from 800mhz. It isn't readily apparent how to do this in the BOIS, but you need to go to the chipset settings | AI Overclocking and move the board speed down to 800mhz, which in turn kicks the memory down to 600.
Truthfully I don't really notice the downgrade in memory speed, but I am seeing improvements in all applications and the game is running smoothly now.
I will try to find out the reasons behind these steps, but for now i have a fast, smooth system and I am happy with it.
