post #1881 of 7032
Sorry I forgot to respond here. I've been at work a whole bunch. My computer lasted the 12 hour prime 95 with no errors or anything at 1.2V @ 4.3ghz . What's the next step?

I guess I have to go a little higher then. When I finally get a stable Vcore should I use what CPUz tells me or what I put in the bios for calculating the offset??
Totally Dubbed gives a good explanation of offset: post 1534, page 154
So you use the manual vCore (not what you see in CPU-Z) and subtract the most common VID under load.

As for using it, of course you should use it, but only after you know for a fact where your minimum manual vCore is for that multiplier and you are completely stable.

You also have to ask yourself if you really want that level for 24/7. I just found my stable level for 4.7 but the vCore was about 1.35 and the temp was 88c. 1.35 and above is definitely on the high side, and the 88c will go measurably higher when it is summer and I end up using a little quieter fans. So even though I am stable at 4.7, I am not sure it good for the life of my chip to leave it at that level 24/7. Therefore anyone new to this needs to find the manual vCore and max temps where you are completely stable for at least 3 speeds in my opinion. So for me I have to find 4.5, 4.6, and 4.7, and believe me that takes a long time but it the only smart thing to do when you are new at this.

Work? Wait, we don't get paid to spend hundred of hours overclocking???

See my post above. What do you want? Max overclock that you can get away with, slight overclock that you don't have to worry too much about? Also check your Windows Event Viewer for WHEA warnings during that 12 hour run. It is possible to get those and still pass prime for 12 hours. There are varying opinions on what that means, but from what I have read and seen it means you are .005 too low on your manual vCore.

Last question:

What is the best voltage for my ram ?
At first I put the 1.5V like in the OP but it didn't worked so I put 1.6V. Should I put 1.65V like in the specification of my ram or is it better to have it a bit lower ?

Haha I wish man

I want a slight overclock (4.3) stable for my gaming! No errors in Windows Event Viewer. I'd like to keep it cool. My temps got a max of 81C during stress testing. So far during gaming with this setup it has (so far) gotten to a max of 65 but I could see it getting a max of 75. I feel ilke thats not too bad, but I would like to lower it slightly if possible. I read the thread about offset and possible settings I could change to optimize it. I'm not sure if all of the settings in this thread are optimal for a minor overclock like mine.

Anyway, I just don't exactly know where to go from here in terms of the offset path or what tests to do

Ignore what you see in the pics for the guide. You need to use the timings and voltage that are specific to the ram you are using. It should give you all that info on the box or stick itself.

If you are happy with the temps and speed at 4.3 which you have already done, then you just need to figure out your offset and set it up. You can try 4.4 if you want just to see where temps go. I would recommend testing whatever level you end up at again when you start using offset and keep an eye on your min and max vCore and speed to make sure it is doing what it should during load and idle. It is a good way to make sure you did not type in something wrong. Also save your bios settings to a profile and save it to a USB in case something happens and you lose all your bios settings, or when you flash to an updated bios.

Cpowa,
To be specific, you need to click on "DRAM Timing Control" on the Ai Tweaker page and enter 9, 11, 10, 28 for the Primary Timings. Then on the main Ai Tweaker page enter 1.65 for "DRAM Voltage."
