Asrock Z77 Owners Club

Z77E-ITX/3570K Overclock

It was time to pull the trigger on the last piece of the puzzle with my rig...

An Intel i5 3570K

My ever faithful 2600K will now go into retirement

As I had previously mentioned I had concerns with the 3570K's heat disappation and decided to look into the black art of CPU Core Voltage Offset Mode Overclocking as a means to counter this; again the initial testing with my 2600K yielded some good results but would the 3570K perform likewise...

The answer is yes!!!

I now have it running at a bomb proof 4.5GHz @ a mere 1.176V effective using an offset of -0.50V so tick the energy efficient box

Now to the performance...

Previously I was able to run the Samsung Green DDR3 PC3-12800C11 1600MHz 30nm Dual Channel memory @ 2133 (9-10-10-21-2N) @ 1.55V however for some reason I couldn't achieve those same timings with the 3750K :confused:

I've now re timed them as follows -

Not such a bad compromise @ 2000MHz (9-9-9-20-2N)

Would it now withstand a "Damned good thrashing..."

Yet again yes

And lastly to benchmark the wee beast once again

Yeah I can live with that :cool:

how does it apply to my asrock board??

Every Intel CPU has a set of instructions embedded as to what Vcore it will need if given an increased multiplier, it's VID ie If I set the multiplier of my own 3570K to 45 the actual VID of the CPU is in fact 1.2059V.

By using a CPU Core Voltage Offset Mode Overclocking setting of -0.50V I'm overiding the embedded CPU instruction allowing my CPU to run at 1.176V thus using less power whilst maintaining an overclock of 4.5GHz and also generating less heat to dissipate.

Make sense?

Anyone tried using the Auto Overclock past 4.6ghz? Is it stable?, I'm wanting to get a Asrock MB for my next build, simply cause of their high auto OC's.

Well I think my Extreme6 is dead. :/

Anyone had trouble with the LAN port? I don't get a link light on either end (tested cable/connection on my laptop just fine). In windows it is detected but says no connection for the broadcom port.

I did a straight swap out from an P68 Asrock Extreme 6 to a Z77 Asrock Extreme 6. I'd rather avoid reinstalling windows where at all possible. All driver installs went fine it is just this last niggly bit.

I am on latest bios 1.90 which was required to get my graphics card working correctly.

Whats up with yours Ollie?

Ollie1132 · 21 Jul 2012 at 14:51

It's constantly restarting for no appparent reason (originally thought it was my PSU but I tried my older PSU and it does the same)

Sounds like you have something shorting out the motherboard.

I once had a similar problem caused by a CPU cooler backplate, reseated the back plate and hey presto instance fix.

The only other thing that may cause that is if the memory loses it's timings and you get a failed overclock loop.

how long have you had it for?

Is anyone using the Z77 Fatal1ty pro?
One reason I bought it was to let me use a couple of legacy IDE drives that I didn't want to replace just yet but unless you turn off the IDE support via the bios then win7 x64 wont boot. Trawling online yields lots of instances of this but no solutions. Anyone have any ideas?

Few months. The motherboard won't overclock at all now. Nothing is shorting the motherboard (Im pretty sure at least) my ram stays at 1333mhz even if I hit xmp and change it to 1600mhz.. :c

Set it to 1600mhz manually?? IVY's native speed is 1600mhz your not actually clocking anything. If this wont work flash the bios.

Sounds like a corrupt bios this to me.

I have it set to 1600mhz manually. Hm I hadn't considered that what to do to sort it? Currently it is running fine (got stock cooler on) waiting for it to reset. Reckon it's safe to flash a newer bios version?

Korsun · 22 Jul 2012 at 22:21

could you send me a link to that guide,mate?
i build my first pc with asrock and i5 3570k,which I want to oc today,thanks

Sorry for the delay jim....

Does that board have dual chips. If so yes. If not I dont see why not just flash it its clearly not working correctly is it, RMA if this does not work.

Flashed it and it didnt work. Will have to rma it now

the joys.

What went wrong with that exactly?? cant you recover from board disk???

It flashed fine. But still having the same issue. It's not possible the cmos battery is dead is it? (doubtfull since it boots and happily sits around for hours on end) The board is technically fine as far as I can tell.. other than not overclocking and the false/random restarts.
