Overclocking i5 3570 (non-K)

Icaraeus · Jun 21, 2014

I read that it was possible to overclock my CPU so I tried overclocking via the BIOS.

I had initially enabled non-k OCing in the BIOS and then changed the values from default to all cores at 40 (4.2Ghz) with the BCLK at 107.5. My computer failed to start half a dozen times so it reset itself. I went back into the BIOS and changed the values to [Core 1 @ 40, Core 2 @ 40, Core 3 @ 39, Core 4 @ 38] and put the BCLK at 105.0. My computer boots up normally and my speed is apparently at 4.0Ghz. I ran Prime98 for 30 mins and it seems fine. Did I successfully OC my CPU from 3.4 to 4.0Ghz or am I missing something?

CPUZ validation? the BCLK change could account for 175 MHz. For the non K SKUs the easiest way is just use intel XTU but that only gives you an extra 4 x 105 (BCLK) turbo.

On CPUZ it's running at ~3988mhz and goes up to 80 degrees at full load (Prime98). Is this safe? It stays at 70 degrees 99% of the time on Prime98 but it did go up to 80 degrees once according to HWMonitor.

Sure it's safe. What does it say your multiplier was?

Icaraeus · Jun 22, 2014

Overall clock speed at 4.0Ghz according to BIOS

My multipliers are:

Core 1 - 40
Core 2 - 40
Core 3 - 39
Core 4 - 38

BCLK - 105.0

Ah you'd be using the turbo boost oc. Probably. Try multiplier 43

Icaraeus · Jun 22, 2014

Which core at 43? I tried all cores at 40 multiple times and my computer kept shutting down after 1 second until it reset itself.

Alpha3031 · Jun 22, 2014

Lower the BCLK back and just do one core 43.

Icaraeus · Jun 22, 2014

Do I put Core 2,3,4 at 40, 39, 38 (only change Core 1 and back BCLK back down to default)?

Alpha3031 · Jun 22, 2014

Yes, and consider installing Intel XTU, it'll give you more info

Icaraeus · Jun 22, 2014

Okay I managed to get up to this:

Is this alright?

Alpha3031 · Jun 22, 2014

If you put +50 mV on the turbo you should be able to get 43. Before you do that what is your current turbo voltage?(you can monitor voltage by clicking on the wrench thing) We don't want that to exceed 1.3.

Icaraeus · Jun 22, 2014

It's staying at 1.216V according to HWMonitor. I started up Prime95 and left it a min before looking at voltage. Also the BIOS is locked to 42 on the multiplier. I typed in 43 but it just changed to 42 when I pressed 'Enter'.

Alpha3031 · Jun 22, 2014

Use the XTU and try again, if it doesn't work still bump the voltage up, and then BCLK to 103.

Icaraeus · Jun 22, 2014

I managed to get it to 4.3Ghz through volt increase. I'm a bit worried about the temps though, is it still okay?

Did some testing and it only ever gets up to 60 degrees. It only goes higher with Prime95, thanks.

Alpha3031 · Jun 24, 2014

Welcome, and those are pretty good temperatures considering most K parts only go up to 4.5 GHz with an air cooler.

zenx · Jun 24, 2014

I know this is solved and all, but just wanted to add that the temperatures in your picture are pretty scary. From what I see you didn't run prime for a very long time and the temperatures are still in the rising phase, they did not stabilize and you have 86 degrees for one core. A lot of things could happen, for example your heatsink gets full of dust over time and that will push the temperatures even higher and yes prime95 gives your cpu a 100% load, but it's only a matter of time till you come across some application that also requires your cpu at full load and you could start experiencing random shutdowns and stuff..

I assume you are using the stock cooler so I would recommend that you only increase the multiplier and leave the clock speeds and voltages alone so your temperature stays in check (I have my non-k 3470 at 4 ghz [40, 40, 39, 38] with a thermaltake nic c4 and it never reaches 60 degrees with prime). You could also aquire some fancy cpu cooler and play with clock speeds and voltages but generally I wouldn't recommend it with a stock cooler. Anyway it's not really worth it since you won't really see any real performance increase because probably your system isn't bottlenecked by that cpu

Cheers!

It only goes above 60 through Prime95. I did some testing and when doing anything including gaming and heavy multitasking it never goes above 60 degrees.

zenx · Jun 24, 2014

Hmm.. okay, well in that case if you have a pc speaker attached to your motherboard you could set up a temperature warning for say.. 80 degrees in the bios that way you can be at least sure what's causing it if you start experiencing issues

just to be safe
