If I am overclocking my cpu, should I set my RAM to 1T, 2T, or Auto? I want to up my ram as well. Any thoughts?

More about : auto

Hey what's up... Overclocking/tweaking ram is of the same mind set as overclocking the cpu. Mostly trial and error and lots of testing. Some can run 1T some can't, it all depends on the motherboard, the actual ram you have, and the voltage your willing to run through them.

The first thing I would do is leave the command rate on auto for now, and find the highest frequency your happy/stable at. Once you have locked down what frequency your going to be running at, I would move to the main timings, and see if you can lower them a bit. Test Test Test... If your good there you can try running 1T can't hurt.

Which setting on my mobo would adjust the frequency of the RAM? And thanks!

Should be able to set your ram manually in advance settings. You should also set the proper voltage manually if you haven't already, it should be labeled on your ram box or the ram it's self.

Hi man.

How's going the OC?

The thing is easy.

1T: Gives you the max performance but not very good stability
2T: Gives you the best performance and stability

Now, keep in mind that if you overclock your CPU using the CPU multiplier, the RAM isn't affected,so, you can set it to Auto or change the settings to the specific settings for your RAM.

Finally, What rated speed is your RAM? Because if you try to run your RAM to a not rated speed, you can kill the MIC of the CPU, the RAM or both.

If is 1T on auto, don't change it.

:lol:  sorry, I just meant that if the mobo set it to that specs is because is stable,so, Why change it?

have you gone through the settings and tried to enter the correct values for the ram?

First:
CPU-Z is telling you something different from the package because it is reading the actual contents of the SPD chips on the RAM. What the packaging is telling you is that you bought RAM that was tested at a higher speed (overclocked) after it left the assembly line. If you will note, the packaging gives a higher speed at looser timings and probably a higher voltage.

Second: I leave the command rate (?) on Auto. I spent a lot of time on my first Core2 system testing and tweaking settings. Based on DDR2-1000 RAM, I found that dropping the command rate from -2T to -1T increased memory i/o about 3%. :) 

Unfortunately, it made no difference in real world performance. :( 

Things might be different with DDR3 RAM.

I am new to the terms "loose" and "tight" settings with RAM, so if you could explain what you mean it would be helpful.

I already changed the RAM ration to 1:4 and now it is running at 1600Mhz. However, I still need to change the latencies to match the mfg's recommendation.

Basically loose timings are higher values meant to run a little slower, and tighter would obviously be lower values. So if your timings are 7-7-7-21, you could loosen them to 8-8-8-24 and so on. Higher timings can help when stability is a problem, but performance will take a hit in the process.
