Check this out:


Is it at such a low multi and cpu speed because of the non existent load? I'm just idling atm

CPU-Z displays your core and voltage real time, you'll need to put it under load to see it at full clock/voltage.

Edit: also what motherboard do you have, what cpu cooler, etc? Is your sig rig up to date?

alright thanks smile.gif

so should I run prime95 and run

Custom, 1344 FFT - 1344FT, Available ram use all your ram but leave 1.5GB (1GB for windows and 500mb spare), and set cycles to 1 minutes. So it should look like this:



So I have 4GB ram total, im using 2.5GB for this test If you have 8GB, use 6.5GB etc.

If you can pass 15-20 mins of this test, restart the torture test and use 1792 - 1792 for the FFT size. Again do this for 15-20 mins.

If you can do both these tests, you have a good indication of the cpu being stable, and you can either go ahead and do an overnight p95 blend test if you want full stability, or increase the CPU multiplier.

You can do that, personally when I'm just finding a decent overclock to start out with I run the Small FFTs option as I don't care about loading up the ram much. This option however doesn't fully stress the CPU so it's not a true test of stability just more or less can the CPU handle synthetic 100% load at your voltage/multi setting.

I run my experimental parings of voltages/multi for about 5-10 minutes and bump up some more until I hit temps I don't like, then I'll back it down on voltage bit by bit until BSOD, bump the voltage back up and run a long prime95 session using your sessions you displayed.

Everyone does it differently but that's what works for me, how are you monitoring your temps?

I recommend Core Temp, pretty nice utility and for those of use with logitech keyboards with the screens on them it'll display temps on that.

Can you explain how to start the prime 95 test? I don't want to ruin anything.

I have never oc'ed before and although I know a lot about hardware, I know jack crap about overclocking frown.gif I hope that's going to change!

No problem it's not that hard, definitely make sure you have a temp monitoring application before hand so you know if you need to turn the stress test off.

Using prime95 is simple:

1) open prime95
2) select the small ffts option
3) click ok
4) it'll open a child window per thread of your cpu, in your case of Core i5, 4 windows + the log window = 5 total.
5) monitor each one for errors, if you start to see errors or you're satisfied with the stress testing results, go to step 6
6) to stop prime95 click test-> stop, click ok. (prime95 icon at top left of the window should go pink)

If you want to start another stress test:
1) click options in the top menu
2) torture test
3) repeat from step 2 up above in first instruction set.

Now the image you posted is from another overclicking thread, it'll be a fine tuned stress test to get results faster but shouldn't be run until you've got a good base overclock figured out.


EDIT:
Check out some of the overclocking guides on ocn as well, it's a wealth of information and more than I can provide nor care to repost for the sake of keeping the forums clean and good info centralized.

Here is one for sandy bridge processors.

Thank you so much smile.gif

I will do these in a second but what is an acceptable temp? I am getting a maximum of 48 degres on my core 3 (I just installed an ran microsoft security essentials?)
post #18 of 65
48 degress, is that C or F, also depends too on your ambient temps.

I wouldn't run your CPU above 80C daily personally but everyone is different.

C* sorry

I'm in Australia so it's in Celsius smile.gif

Also what do i do here? it asked to change the memory amount?



EDIT: I have 16GB of ram if that helps?
post #20 of 65
48C is good but an install of Security Essentials isn't a full load test.

Close that window, you don't need change anything in Options -> CPU.
