I get two "workers" err every time I run it. The rest is fine though.
Since Prime95 can go on testing even when two CPUs are down, I've been able to enjoy good stable results on all the other CPUs.

This lead me to think about the times I used my 920 on Stock cooling when it would easily exceed 80 C and usually be around 85 C on max load. (I used to catch a 90 C every now and then too!). This was without any O/C.

So I'm starting to believe that I may have beaten Mr. CPU4 and Madame CPU5 to death in those earlier, overly hot, 5 full Stock years... Is this possible?


Nah that's usually how it goes. Every core is an individual. Some run a bit hotter and some need a bit more voltage to run a specific speed. I think its very unlikely you did any real harm back in the day. You just need to give it some more voltage that's all.

When your CPU can do +12h of prime95 with no failed workers then you can call the overclock stable (though it might not be rock solid even then).

its common practice to disable Hyper Threading thumb.gif

On Toms hardware years ago there was a topic on how much electric OC pulls on these chips i.e - 4.0 mhz , 3.8, 3.2, 2.66 and 3.8 seemed the best all round as in electric in return for speed.

But someone on here I think explains that all chips are not equal - such as mine, i can reach higher clocks on just default therefore same electric used thumb.gif

Im pretty sure you can get a stable overclock with turbo off and hyperthreading off. You would not see much of a difference with hyperthreading off unless you use applications that can actually use it. (Not that many atm)

Thanks for the bit of info ladcrooks, now I'm feeling somewhat more in terms with settling for 3.8 ghz. thumb.gif

Although I've managed to take malzmidx' advice and get the core speed to 4 ghz by Disabling Hyper-Threading ; I left Turbo still Enabled. (I just don't know why I don't Disable Turbo, maybe I want to see that "x21" there, maybe it's me wanting to squeeze every bit from the bclock...)

Current VCore is 1.3.1V


Max Core Temp: 72 C


However, in Prime95, one of the cores is still giving me the finger.

What the hell is wrong with that little brat?

Must I absolutely feed that sucker with more Volts to get it to do it's job like Bit_reaper's suggestion?

If I remember correctly, you should be able to use x21 without turbo enabled lol. I was able to do x23 with my 950

What sorcery is this? eh-smiley.gif

When I disable Turbo, I'm left with manual multiplier settings, which can only be set as high as 20. I cannot manually set it to 21 ; thus, I let Turbo handle it to achieve the x21 effect.

Am I missing something here?

May be different with i7 950's? Or maybe it was my motherboard in general. I never got my 950 past 3.9 though. Not sure what step it was but either way I couldnt do anything.

Try at 3.8GHz, if you get that stable you can try going up. Every chip is different though, all you can do is keep trying, find a stable lower setting and attempt to work up is a good method. Have you confirmed the 191 baseclock is fully stable, a 191x15 multi for example would give roughly stock CPU frequency and confirm baseclock/ram is good. If you've done that it's really about how much volts/temps you want as your personal limit.


Edit, 930 and 950 has extra multi's available above 21, 920 doesn't.

I know that lol. But my confusion is: Shouldnt OP be able to get 21x multi without turbo??

On some boards you're able to set up to 21x, on others it's a setting that forces 21x to always on. On Gigabyte, i think, if you set 20x it will turbo to 21x when needed as Intel intended and the "turbo" setting forces it.
