DELETED_5350

What memory are you using as you might have trouble with 1666mhz.

In order to get the value you will need to adjust the memory multiplier in the BIOS. With a good cooler you should be able to reach 4ghz :)
 
leave the memory as it is, it hardly makes any increase in performance, uses more power, makes the chipset create more heat and therefore lowers the max possible overclock
 
To overclock your memory you can play with the bios settings. You will see in the opening bios screen a option to change the ram frequency (change the ratio) you might want to give that a try. If the overclock is not successful there will be no real downside except the bios will reset to the last successful boot settings. Give it a try.

If you look in the manual that came with the board there is quite a bit of information there that tells you how to change the settings.
 
Have a look in your bios and see what is the voltage on your ram. I suspect it is 1.5 volts. Up that to the ram spec of 1.65 and you should be good to go.

And have a look and write down what your ram timings are. Look in the bios or in CPU-z if you use CPU-z compare the SPD values with the actual memory values.

Last option , it just could be that your ram just will not overclock. But I doubt it.
 
I use an FSB of 250MHz with a memory multiplyer of 6.66, gives 1666MHz on OCZ Gold 12800 (1600MHz).
 
A low end GFX card like HD5550 or Nvidea GT240 will improve your graphic performance and release RAM back to the system. This will cost ~£50. If you think it worthwhile.

I do not know if the OCZ gold is a lot better than your Corsair, or enough to make a difference.

Using Crosair XMS 3 8gb. (CMx8gx3m2a1333c9).

Looks like you bought the 1333 MHz rated RAM, so you may struggle to get it running at 1600+. Should have bought 1600 MHz rated version as it's the same price anyway.

Assuming your ram will run at those speeds, you'd be looking at an overclock of, say, 166 bclk using the 10x mem multiplier, or higher bclk using the 8x mem multiplier. Your CPU will do 4 GHz no problem, but you'll need a decent cooler. Doesn't need to be as expensive as a H50 - £30 air cooler will do just fine, but the H50 is nice too.

If your RAM doesn't like going faster than 1333 MHz, you'll be stuck on the x8 or even x6 mem multiplier to keep the RAM speed down when overclocking your CPU.
 
There's no reason that ram should give you problems overclocking. You could for example in theory have a massive 4.4 GHz overclock on your CPU with 200x22 settings and still run your RAM on the x6 multiplier (assuming your board offers a x6 - can't remember if mine does now). If your board only offers a x8 as the lowest mem multiplier, you'd have to limit your bclk to 166 to keep the RAM at 1333 (166x8), which in turn would limit your CPU overclock to 166x20 = 3.66 GHz.

Out of interest why are you more concerned about a RAM overclock than your CPU, or is the CPU sorted? And what software are you using to try and overclock? Better done in BIOS really.

Totally agree with this chap. Ram is not as important as your CPU when you are doing a overclock. The real world differences are hardly noticeable between 1333 and 1600.

Your board will allow you to overclock quite a bit and the ram options are good too. Take your time and small steps is the way forward.
