It has been surmised that I need to upgrade my memory to possibly alleviate some weird experiences I'm having with Sonar. So, I want to upgrade from 4 to 8 GB. However, the memory I installed originally is not available any more. I can find PC2 6400 RAM still, but not in the same timing as I currently have, which is 5-4-4. How important is it to have the exact same timing on the add on memory? Options I'm finding now are 4-4-4-15, 5-5-5-15, and 6-6-6-15. If it's OK to mix, which would be the best option? Thanks.
I wouldn't mix myself... I had a hard time recently even getting a brandy new gigabyte z77 board to recognize a 4x8GB pack of corsair vengeance... even with XMP config, I had to fiddle around in the BIOS to get the timings set right... PITA if you ask me, these high falootin' computers with their fancy pants RAM chips...
I have an unopened pack of OCZ PC2-6400 (Titanium Edition) 2x2GB running 4-4-4 @2.2V here... If it helps I could send it to you if you want to try before buy sorta thing... figure you might be able to just run at your current timings (or higher) and undervolt these new sticks... keep in mind, the 4-4-4 and 2.2V go hand in hand, but that doesn't mean you can't undervolt, etc., to match things up. I certainly wouldn't overvolt your old chips... Let me know, and I can drop them in the post, and if they work perfrectly for you I promise I won't ask for more than... $175 or so for the pair... :)
