can't get it right

[daleevr]

Hi if anyone could help me understand a memory issue I would appreciate it very much and thanks in advance. I have built my first computer, I am not a overclocker. I have a DX38BT mother board with four gigs memory 1333 corsair. My question is why does EVEREST show my memory at 1066 and my memory is 1333. My bios is right I think!

does your bios read your ram as 1333... if not you have to manually change it to

You have DDR3 1066 which is sold as 1333. The standard voltage for DDR3 is 1.5v and what companies do is test memory at higher voltages, lower timings, faster speeds and when the have a bunch that can operate consistently at these settings they will program the settings into the SPD (Serial Presence Detect) chip on the RAM as EPP (Enhanced Performance Profiles) settings and then sell them at those speeds. What you need to do is download and run CPUZ and click the SPD tab and you will see all the settings for your memory. The motherboard defaults to the Standard JEDEC settings so you will have to go into the BIOS and manually set the memory to the settings you see in CPUZ.

This is an example from my memory which was sold as DDR2 1066 2.05v

Thanks to you both. I have downloaded the cpu-z and see my setting. I will go into my bios and check the settings and make the changes. Thanks again!

Hi, I gave that a try and my computer would not boot. I did hear three beeps. Had to move jumper and set everything back as it was. The question I have is the freq. setting is at default, it would not let me set it higher than 400. My memory is 533!

you should be able to set it higher than 533 for 1333 you should be setting the memory for 667. The choices are limited by the FSB on Intel chipsets due to the number of multipliers the board has built in so if your running a 1066FSB give 1333FSB a try and see what different memory speeds it gives you.

Looking at my bios settings, my fsb is currently running at 1333. It shows the memory at 1066. My freq. setting under memory overrides are set to default. The other choice available would be automatic. Where should this setting be? And thanks for your continued help!

I am unfamiliar with Intel's BIOS, I don't know if they use Award or AMI. There should be advanced settings for the RAM where you can set it to manual and input your desired settings. Default and automatic are the same thing.
