I am a little confused on how to get the RAM 1:1.

What would i need to do my ram stock is 800mhz. Everytime i raise the fsb, my ram speed goes up as well.

Okay, it's partly because if the RAM/CPU ratio is at 1:1, the RAM processes the information sent by the CPU exactly. In this case, neither the CPU sends more the RAM can handle, or the RAM stays partly idle, because the CPU is sending less the RAM can handle. Basically you even the matter. The CPU sends - the RAM processes.

Also, this allows your overclock to go higher. Let's say, for instance, you have a higher RAM than CPU ratio, then your RAM frequency would be higher. If your RAM isn't overclocking friendly by X or Y reason, then you would be stuck. So you "lower" the RAM frequency (which is good in your case, as it's a 1:1 divider, the best divider for Intel CPU's) and your RAM can be squeezed more. If the RAM is your obstacle in your overclock, then you can gain more speed.

For example, in a old P4 2.4A I had, I went to 3.0Ghz on a Higher RAM than CPU divider. I made the divider 1:1 and I could get to around 3.3 Ghz. So it definitly does matter, and it makes the CPU work better in my opinion.

The only exception may be if you have severely limiting RAM and a CPU that is an excellent overclocker. That is up to you to determine, tho. Does a 5:4 divider at a super high CPU clock offer better performance than half the FSB in 1:1? Well then, stick with 5:4. At the same time, running RAM faster than the CPU offers absolutely no performance gains (the CPU is doing the processing, RAM merely receives data as it is fed to it...). I don’t know why motherboard manufacturers even offer dividers to run RAM faster than the CPU, but they do. So, please, for my sake, don’t go setting your CPU bus speed to 133 mhz and DRAM frequency to 200 mhz (or 400 mhz, depending on how your BIOS lists it).
EDIT: If you want to find your 1:1 Divider, just multiply your FSB by 2 and select that number in DDR Frequency.

EDIT2: Damn, double post.

That vCore isnt that high for that OC.

Thats the same vCore and speed as mine. Temps are even the same.

Only difference is that im running 400*8.

My CPUs VID (stock vcore) is 1.3250. Week 27A btw.

Seems a little high to me, but as was mentioned, CPUs can vary.

Stock? You mean you left your Vcore set at AUTO in the BIOS? I wouldn't do that, chances are you're using much more than 1.325. What program are you using that told you that was your Vcore? Because that is the exact voltage listed as the max by Intel.


grkgus, first off, you stated you have had this system for 1 day and you are already at 360FSB.....so I am assuming that you did not use the 'slow n steady' method of overclocking.

You will get a more stable, higher overclock by making small changes and testing each one thourghly, but that's your choice.

To get 1:1 on your RAM and to stop it from increasing on it's own, you need to take your RAM speed and timings off AUTO. Set your RAM speed manually and it will lock itself there and not change it unless you do so. Conversely, you will have to manually increase the RAM speed manually everytime you increase the FSB to keep the 1:1.

I did take them off auto, but in the bios when changing FSB the speeds of the ram change respectivly. All the timings go up with the FSB.

I did get it to 3.0 before i did 3.2 and prime95 ran on both with no errors for 4 hours. PI finished in 15 seconds on 1mb

I will try a bunch of different things everyone mentioned here though. I really appreciate all your help. I will keep you guys posted with results.

Thanks
