i5 3570K quick test.

[stulid]

4Ghz (turbo disabled, ratio set to 40X, thats it), walk first before you run


idle,

Prime95,

 

[stulid]

What have you changed the voltage to for 4Ghz? Is it still at stock? I realise screenies show different voltages but wondered if they were accurate with this cpu?

4.5Ghz please

Voltage is default, only the CPU ratio is adjusted for that pass.

 

[stulid]

You going to push it tonight or take it in easy steps.

Football is on, will take it easy, 4.3Ghz next, then 4.5Ghz

 

[stulid]

Indeed, this is a full retail chip right?

Yep.

 

[stulid]

4.3ghz, LLC set to normal, vcore increased a few notches, could be refined more if I had time,

IDLE,

Prime,

 

[stulid]

4.5ghz going now.

 

[stulid]

Edit: At idle, how come it hasn't clocked down? Are you running with speedstep disabled?

As it says above the pics, turbo disabled, this disables speedstep too.

 

[stulid]

4.5ghz, bclk sorted so its 100mhz exactly and not that silly .9 extra.


Prime95 kept failing early on, or a Bluescreen and restart.

Tweaked the Vcore two notches more 1.320 set in the BIOS, LLC set to high.

Finally got Prime95 to do 20mins (obviously thats still not considered stable but I usually find that a worker stops within 10minutes if there is an issue)


Idle,

Prime95,

 

[stulid]

Not used burntest, and to be honest I need to flash the BIOS to the latest version (current got F5 on it) and have to crack on with a few other things to do with this board, will be revisiting my OC and hoping to tweak it properly to maybe reduce the Vcore one notch or two etc.

Also want more than 4.5Ghz

 

[stulid]

Any chance of a cinebench run at 4.5, cheers.

 

[stulid]

That seems like very cool temps for 1.32v compared to other reviews. Most of those were 3770k's so if the 3570k can do this then the 3570k looks much better for overclocking.

For reference my 2500K @4.5Ghz using the same cooler averaged 52.75c across the cores running Prime.

The average of the 3570K on the previous page is 56.5c


Different boards were used though.

 

[stulid]

1 thing to note is that the OP stated that Prime lasted for 20 minutes before it failed.
.

I never said that.

I cant be bothered to sit and watch it running prime95, so I give it 15-20mins to get toasty and then take the temps.

It was going fine until I stopped it after 20mins.

 

[stulid]

Any more testing stulid? really looking forward to more results, as Monday approaches I need to make a firm decision whether to buy or not, I'll be happy if it is totally stable at 4.5Ghz-4.6 at low volts and temps but I have not seen any real reports of this yet.

Not looking good to be honest.

 

[stulid]

Is heat causing the problem (when the voltage is pushed higher)?

NO, its just not stable over 4.5Ghz, not doing anything special either.

 

[stulid]

4.5Ghz,

edit...Using the HD4000 GFX.

 

[stulid]

So, in your opinion what would be the highest stable 24/7 overclock, for your particular CPU? 4.4Ghz?

4.5Ghz is rock solid, strange that it ****s up with anything more.

Could be the betaBIOS, could be a lack of Vcore.

 

[stulid]

Could just be a **** chip?

And after owning a 2500K that was 5Ghz+ (ran SuperPI at 5.2Ghz), could have gone higher if was a brave man with the Vcore.

I guess I was expecting the same.

 

[stulid]

So if you had the choice which would you go for in my position, I have a z77 board all ready, 2500k or 3570k?

Honestly, I want my 2500K back.

 

[stulid]

hmmm, looks like I might have 4.6ghz nailed.

a bit at a time I'm getting there, shoving 1.35v up its butt.

 

[stulid]

What kinda temps are you pulling currently at 4.6Ghz Stulid? isn't 1.35v and 4.6Ghz still with in the "reasonable" tempratures for IB?

prime95 has been going for over half an hour now(I usally have issues around 10minutes if it's going to stop)

temps recorded,

max 64,71,70,64

current temps right now are low to mid 60's
