Proper RAM Setting - Am I getting everything I can?

[ccarterc]

While back purchased the Sabertooth X58 mobo with DDR3 Patriort Viper II Sector 5 RAM 1800 PC3 (14400). Saw the other day during boot, it said RAM loaded at 1066 MHz. Wondering if I have been a moron running ram at half speed for the past year, I got CPU-z to check what's going on. Now I am more confused than ever.




Does the comp automatically choose timings table to use or does it change during use? Are my settings correct and running my ram at optimal speeds?

Here is my ram: Newegg.com - Patriot Viper II 'Sector 5' Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1800 (PC3 14400) Desktop Memory w/ 3DMark Vantage Model PVV34G1800LLKB

If your board has a XMP setting in the bios, use it. Otherwise you'll have to manually set the XMP speed, timings and voltage.

How can I tell which timing table is being used? Is the JEDEC#2 being used currently since it shows 533 mhz and my DRAM is 534mhz?

[SugarJ]

Yes, it's using the JEDEC#2 profile, only giving you DDR3-1066 speeds. You have to double the speed shown in CPU-Z to get the DDR3 speed.

That being said, memory bandwidth is not usually a limiting factor for most people and you may not notice any speed increase in your daily use.

So I set it to XMP. Now I got this:

Does that mean I am operating where I should be now?

Go in the bios and change the memory multiplier.

Yes, that's now running at DDR3-1800.
