Need Ram advice

So whilst spending most of the day trying to fix the ubuntu install on Hood I noticed that my ram was running slow, i.e 1066 instead of 1333. Set the BIOS to force 1333 and reboot and still no dice, so took the ram out and tried in my daily driver (same M/B) and i had the same problem. All my other ram brands work as it should at 1333 but this patriot stuff just won't play ball even though its rated at 1600. Given that there is no way to overclock these boards everything needs to be running at full speed so i am now pondering more RAM.

The question is what RAM to get. I've spent most of today browsing the top team forums and have got completely confused.
Almost all say that bandwidth matters - this i get and that would mean 1333 as a minimum
Voltage - does it matter if it 1.65v as most of mine is and it seems to be running fine? The board prefers 1.35 or 1.5v
Latency - some say it doesn't matter, some say it does.

any ideas or suggestions as to what to buy - money is reasonably tight as i am saving up for some upgrades
 
Every body used to say to me a while back that with the 1366 i7's that ram speed and latency did not matter. I had a hard time believing this so I started testing. I found that both made quite a bit of difference, I found that with a 980X at 4.3Ghz I could shave up to 1 1/2 minutes off frame times with ram speed and timings. The Timing's part can be a little tricky, tighter timings do not always mean faster you have to find the sweet spot for the ram you are using and if you get any of the timings to far off balance you then create a bottle neck which will cost you throughput. It is best to let the memory run at default timings if you do not want to spend the literally days of testing you timings to find the best. Although it can be worth it if you have the time and patients. There have been some memory brand's that I have not been able to run better than the board default's Patriot being on of them but most will.

As far as the 1.5v if you want your memory to run at it's best then get 1.5v memory as far as it running at advertised speed and timings that is pretty much a shot in the dark and depends if your MB recognises the memory profile or not. The G Skill 1.5v 1333 memory has good timings 7-7-7-21 @ 1.5v for a reasonable price but I do not know that your board will recognise the XMP profile. http://www.newegg.com/Product/Product.aspx?Item=N82E16820231405 or http://www.newegg.com/Product/Product.aspx?Item=N82E16820231492

Cheers for that, i doubt the board will recognize XMP - it will have to be SPD based - which makes things a bit trickier

Edit:- Just managed to track down the 4Gb kit version of that ripjaws for £21 + shipping. I'll get enough to do 1 machine and see how I get on. Plus looking at some of the photo's here and on other forums it looks like this is good stuff - its the same stuff Hoth17 mentioned and it looks the same as the stuff patriot has in his rig
