1st time OC - not sure how to proceed - Page 2

post #11 of 17
Thread Starter 
show_oc.php?id=1600963

this is what i've done so far.

-cancelled turbo mode
-set cpu voltage to manual (1.275v)
-set multiplier to 18
-set RAM to 1600mhz and 7-8-7

i haven't touched voltage in either RAM or CPU yet, and the system seems to be stable.

***does it make sense that i'd be able to go to 4ghz without upping the voltage, and still maintain stability?

***also, i'm still seeing multiplier changes (x4 in idle 800mhz to x18 load 3600mhz). is that normal?

Everything looks good, but:

I would leave memory an vcore on auto for now until you get the hang of things and just up the multiplier until it is unstable and then try to up your vcore just a little until it is stable.

On the memory, you could also set it manually to the factory settings if you want just so you know it is running at the rated speed.

You are wrong. Memory ratio does not matter at all on AMD systems with the integrated memory controller. This is not 775.

You probably won't need as much voltage as everyone else, apparently Phenom IIs overclock better/require less voltage when cooler. This can be seen when you put a Phenom II under LN2, it apparently requires less voltage for 4Ghz than on air. Since the NH-D14 is pretty much the best air cooler out there, your prospects are looking very good here wink.gif

The multiplier changes are normal; this is called Cool'n'Quiet. Some people recommend disabling it, but I being a slight environmentalist and favouring running cool recommend that you just leave it on because it will most likely work for you 100% fine even at 4Ghz (as it has for me). Cool'n'Quiet downclocks the processor during low-load scenarios (i.e. non-100% load requirement).

Yeah you're right, missed the cool n quiet feature. Thx! smile.gif

Should I do anything about the CPU-nb? It's currently at 2000, isn't it bottlenecking the 3600 oc on the CPU ram-wise?

1) Get the term "bottleneck" out of your head. It's just something that's thrown around on OCN because people have nothing else to say.

2) Increasing the NB Frequency has shown to yield some performance increases. With a a 3.6ghz CPU, a 2400/2600mhz at 1.25/1.3v NB is pretty standard. At 4.0/4.2ghz CPU, a 2800/3000NB at 1.4v pretty standard again.

Don't worry about the NB Voltage. The important one is the CPU/NB voltage.

Also, if you're going to change anything, do it one thing at a time. If you change your RAM, CPU, and NB all at the same time and some instability occurs, then you can't really diagnose which one was the problem. Get one thing stable at a certain speed, and then bring all the others up one by one. It's incredibly tedious, but it's the best way to insure stability.

thx, helped out a lot. and of course i'm doing one thing at a time, not that much of a noob smile.gif

anyway, running stable now at 4.2ghz (25-39c) 1.3v, and 1600mhz @ 7-8-7-24 1.5v. not gonna oc my gpu, since it reaches 68c after excessive stressing, so i don't wanna see it go over that.
did install my old 8800gt tho, metro 2033 looks great with physx biggrin.gif

thx guys for all the help!

It usually always bottlenecks memory access times out of the box, but I don't believe an NB clock speed will ever bottleneck the clock speed of anything else (except maybe the RAM if the RAM is running at ridiculously high speeds, maybe). You will want to up the NB clock, it gives a big performance increase due to additional memory link bandwidth.

You may have an option to increase the GPU fan speed, allowing it to run cooler and giving you overclocking headroom. Even then, I'm pretty sure it can take a lot more than 68C.
