Although SB and IB CPUs they are capable of running at 1333,1600,1866, or 2133 the official support speed is DDR3 1333.
So when you set up a system, at first boot it should be set to 1333 regardless what RAM you installed.
First step is to set the motherboard to Optimized defaults. It goes by the CPUs spec, which should be 1333.
Unless some motherbaords have a workaround, but I ve always had to manually set the speed or the XMP profile after the initial setup.
Sandy Bridge memory standard is 1333MHz, but I think Ivy Bridge got a bump up to 1600MHz. Problem is, you have to find RAM that has a JEDEC standard of 1600MHz. If you find RAM with the correct JEDEC standard, it will automatically recognize it in the BIOS as 1600MHz. Most of the RAM I've looked at is still 1333MHz standard, but with a couple mouse clicks in the BIOS, it can be set to w/e speed it is advertised as....i.e. 1600, 1866, 2133, etc. It is such a simple task to turn on XMP in your BIOS and change your RAM speed, there is no need to look for a workaround.

I stand corrected. It does seem Ivy got the bump to 1600. Not sure why I was still thinking 1333.
Thanks for the correction kbrady.
OK guys... I just pulled the plug on buying the 32gig RAM kit at:
Newegg.com - CORSAIR Vengeance LP 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CML32GX3M4A1600C10
Once installed, do I need to do anything to the bios to maximize this upgrade?
I did a little further reading on SSD and numerous sources have these as not being as accurate and reliable as standard hard drives. So, since my machine is primarily for business purposes I need absolute reliability and longevity.
For now, I'll stick with my new Western Digital VelociRaptor WD2500 HHTZ drive which contains their latest technology.
My 32 gig kit arrived to day, and I just got 'em installed.
I know my machine recognizes all 32gigs of RAM because I used Belarc Advisor to give a read out of all components in my system and under ram is shows the 32gigs there, so best I can tell at this point all 4 sticks of ram are working properly.
Unless there is some test you guys know of that can be run to verify this.
Now that I have these installed, do I need to do anything to the bios
to maximize this upgrade?
Well, I guess I cheated in buying a computer that is already overclocked to 4.0ghtz (I bought it from Velocity Micro)
I went in to the BIOS and XMP was already enabled and the RAM is already running at 1600, and Timing 10-10-10-27.
So, I should be good to go... right?
It would seem it is running as it should be.
OK, so after installing the new 32gig RAM kit...
OK, so I went to Fossil Free Online CPU Load or Stress Test.
and clicked on 100% then ran CPU-Z Validator and the results
can be seen here: CPU-Z Validator 3.1
Couple of questions...
1) Why does it say "Rejected by CPU-Z 1.61" ?
2) Why is "Freq : 4000 MHz (100 * 40)" highlighted?
3) Why is it showing "RAM Speed : 800 MHz" ?
I don't know why it says rejected by CPU-Z, as I've never tried to validate anything through it......google it to figure it out, I'm sure someone has explained it.
Frequency is what you are trying to validate, it is the clock speed of your processor.....4000MHz = 4.0GHz
800MHz * Dual Channel = 1600MHz
Actually, that is incorrect........what I meant was 800MHz DDR(Double Data Rate) = 1600MHz
It's been a long day.
