Ram 1600mhz or 1333mhz?

I just recently found out that canadacomputers (store that put together my computer) had installed the ram running at 1333mhz although the ram is 1600mhz,
i went into the bios and just changed the system memory multiplier from Auto to 16.00
but beside the 16.00 to its left it says 1333mhz under the (SPD)

i checked on cpu-z that my ram is going at 800mhz, x2 so 1600, just wondering if i had changed the settings right in order for the ram to run properly, or is there something else id have to change?
timing or etc,

im running adata 2x4gb 1600mhz ram.
i5 2500k
gigabyte Z68AP-D3 mobo

If your DDR3 memory modules have XMP profiles in its extended SPD you can also make a change to Extreme Memory Profile (X.M.P.) setting in the BIOS setup to use the XMP profile stored in the SPD EEPROM chip of the memory module.

Cpu-Z is usually correct. If it says it's running at 800(1600) then it probably is. Make sure your using the latest version of Cpu-z. Going from 1333 to 1600 is not going to be a huge increase in fps especially if you have a discrete graphics card. Integrated graphics cards get more of a boost since they are using your actual ram is graphic memory. And even then it isnt going to be that much.

Not exactly what your going with but the difference between 1600 and 2400 speeds is about 3 fps. (for the G Skill Ripjaws X), and even that is within the margin of error.

i bumped up my Dram voltage from 1.5 to 1.6, that'd be fine right?
the bios indicated there was some issues with voltages due to overclocking not sure why so i stepped the ram up to 1.6,

1.6 is fine for adata 1600mhz (2x4gb)

Intel's specification for Sandy Bridge Processor safe memory voltage is 1.5V ± 5% (i.e. between 1.425V and 1.575V).

I'm pretty sure that 1.6V should be OK but don't increase it beyond that.

the voltage says 1.55-1.75
thats why i went in the middle at 1.6, i accidently put it to 1.16 than my computer crashed after a restart lol

Hi there,

It supports Intel Extreme Memory Profiles (XMP), so go to BIOS and enable XMP.

Done. No need to do anything else.

so should i keep the multiplier at 16 or no?

XMP is a profile stored on the RAM.

By selecting the XMP, BIOS will adjust itself whats needed.

You have two options:
1. Use the XMP profile

2. Manually set the memory Voltages and Timings.

I've always gone with option 2 because I want to use the tightest (i.e. quickest) memory timings.

hm i used auto timings, and the XMP profile, theres two options on it, disabled and profile1, i didnt sure what it was so i left it at disabled, and my voltage it at 1.6 and i left the timings cause i know nothing about that,

windows index is reading my ram at 7.9 atm though, i guess i should be okay without adjusting the timings?

Works well, leave it be.

BTW, check the difference. No performance gain.

RAM speed comparison - We're looking at a less than 2% difference from the fastest to the slowest.
