This will most likely be a non-understood ramble for those that don't do build their own systems.
I finally decided that it was time to move CS2 off of my AMD 2600+ system w/1gb ram and put it on my AMD 64 4000+ system w/1gb ram. That 1gb ram thing bothered me though so I ordered 2gb of Corsair matched DDR to go in the MB (ASUS A8V Deluxe).
Well the new 2gb of DDR ram worked fine if I took out the initial 1gb of ram but naturally, that was not what I wanted. I wanted all 3gb to run in the system. (Wouldn't you?)
So off to Corsairs website to see what gives. After a lot of searching and reading through their help forum I pretty had figured out that the two different sizes and revisions of DDR ram just were not going to play together. (Seemed to be their mantra. No matching size and rev, no nice playing together)
What was worse is that if I left the two matched 512 mb sticks in, the system ignored the two matched 1gb sticks. So I had to pull the two 512 sticks.
A couple of times in Corsairs help forum flashing the BIOS to a newer BIOS came up as a possible way to get the system to see two sets of ram. My MB came with rev 1007. They are already up to rev 1017 and even have a beta 1018 out.
The new 2gb of DDR came with stickers on it saying 3-3-3-8. My old DDR was 2-2-2-5. Corsair recommends running the 2gb at 2-3-3-6 (3-3-3-8 is the JEDEC standard).
Well I set the BIOS to 2-2-2-5 and the 2gb booted and tested (memtest) fine. So today I flashed to the BIOS to 1017 and set the BIOS the way I wanted. Confirmed the 2gb was still fine at 2-2-2-5 w/MB overclocked 5%.
Next Step, re-introduce the intitial 1gb of DDR. Success!
The system now sees both sets of Ram for a total of 3gb w/2-2-2-5 memory settings.
The OS loads off of two striped Raptors (boot speed and program load speed is pretty quick). There are two other hard drives set up for data storage and scratch discs.
If I don't build another system this fall, I'm thinking I might upgrade my raptors and my storage and scratch discs as Core 2 Q6600 processors are still a bit pricey for me. That and I'd have to invest in a new case, power supply, video card, etc.
I did find it annoying that the MB was released with specs that support 4gb of RAM, yet
the initial BIOS rev was 1003, my initial was rev 1007 and it took newer that that to get proper ram support on the MB.
Now to check if I can see any real performance gains in CS2 and LR.
