Push your GPU as hard as you can. Gaming wont improve from OC'ing ram...at all. Pending on what your using for a GPU you might run into a situation where overclocking your CPU will net a benefit. but I can play BF3 on full ultra settings at stock. overclock the GPU and FPS goes up by about 5 avrage. CPU has no affect what so ever on my set up.

Ok, here's some multipliers and voltages that you can use as a rough guide to get you to 4.0ghz stable:

 

CPU: 200 x 20 = 4000mhz 

CPU voltage: 1.45-1.5v

 

NB: 200 x 13 = 2600mhz

CPU-NB voltage: 1.35v

 

HT Link: 200 x 10 = 2000mhz

Leave this voltage at stock.

 

It is very important to overclock the NB when overclocking your cpu because it helps to stabilize it, and it gives you a big performance boost.  When overclocking the NB make sure not to touch the NB voltage, instead you have to raise the CPU-NB voltage.

 

Edit: That guide up there that mrinnocent linked to was written by Slappa, a very skilled overclocker on this forum.  I would pay attention to it if I were you ;)

I think that may have been the problem, I was trying to stabilize the CPU before I messed with the NB. I will have to try this tomorrow.
post #35 of 48

Overclock everything one at a time (i.e. CPU multiplier, and do not put any focus onto anything else until you are done that).

What motherboard are you using by the way?

Ok so which is it, do I do the CPU and NB at the same time or do I do the CPU and stabilize it and then the NB? I'm getting conflicting information here...
post #37 of 48

CPU and NB at the same time.  Once that is stable then you can play with ram timings.

try to stay under 1.55v and your HT link at or around 2000mhz (it works the best between 2000 - 2400 but 2000 in particular tongue.gif) and u north bridge at 2600mhz to 2800mhz increase ur northbridge to 1.35v to 1.4v check and cross check ur maximum multiplier its usually 19 or 20 and check what speed are u getting at stock usually 955 BE goes upto 3.8 with stock voltage i guess correct me is i am wrong guys and as for the timings of RAM it would be safe if u turn it to auto for the time and once u know your limits u can tweak around with ur RAM in the last . Remembr one thing do small increments and overclock one component at a time try to run the other components at stock or underclock them till that time smile.gif
hope that help you smile.giftongue.gif

Let's make it easier to read,

1. Keep your voltage under 1.55
2. Keep your HT Link as close as 2000Mhz as possible
3. Clock your CPU-NB to 2.6-2.8Ghz
4. Have your CPU-NB (not NB!) at 1.3-1.4v (Personally, I can run 2.6 at 1.25v...but 2800 doesn't even post at 1.35v) <--- I have 4 Dimms if that matter, maybe eith less it'll be stable wink.gif
5. Make sure you're not using the stock cooler and it is seated properly.
6. If your have an awesome overvolting board like the Crosshair V, make you you type the voltage properly.I have set 1.9v onto CPU once.

Well you can use the stock cooler for 4.0, it's just not good, high temps and loudness D:

If you where running a high end GPU set up like 6990/590/580SLI/6970CF then yes, you will get a few Frame's while gaming. but you can run the test's yourself. remove all overclocks and play a game, take not of FPS. Then overclock to your highest stable point and check your FPS.

I beg to differ. My 955 was bottlenecking my single 6950 (ulocked to 6970 @ 930 core) in battlefield 3. I now have it at 3.7 ghz and it no longer is.
