what is the default voltage of a completely stock 3570k at load? i can't, for the life of me, find it in any review on the major sites...

I'm getting 1.104V at stock with Prime95 large FFT stress. Don't take it as a definite value as it may differ from one chip to another but generally I find Core i5 3570K needs more voltage than Core i7 3770K.

Should be getting mine on Thursday. Will be a huge upgrade coming from my E8400. Will post some comparison benches.

I have mixed feelings on this, I don't feel it helps anything. It takes a *lot* to kill a chip with overclocking, and usually if you're degrading a chip it takes months/years to do so. The big issue is that you will hit an overclocking wall *well before* you get into an area there will kill the chip immediately.

For instance, my Sandy Bridge CPU hit a wall at 5ghz (with admittedly high voltage, near 1.5vcore) and could not go farther no matter what. But it wasn't anywhere near being volted enough to kill it overnight.

I'd agree about hitting the dreaded wall well before you hit the danger zone of killing the chip unless you try some insane amount of voltage. My chips wall looks to be around 5.5ghz

Resale value of the K chip I'd think would be better if the insurance plan is/was purchased.

I bet intel is making a killing with the tuning plan warranty. I see it as being completely worthless, I mean, as I mentioned it doesn't help you overcome the OC wall - the OC wall is hit well before you ever get into the voltage or temp danger zone. My 2600k BSOD's at 5.1ghz even though the load temps are like 70C, and tjmax is above 100C.

Seems like a money grab for intel, it could be beneficial for exotic LN2 cooling but otherwise? meh...

CPU arrived. Didn't boot. I suspect my "22nm" Z68 board was shipped with a non-22nm supporting BIOS. Gonna go exchange it for a Z77. They should have those in stock now.

3770K from Microcenter on an ASRock Extreme 6 board.

My goal was not to push this to its limits but to just go for a moderate, easy, safe OC. I have settled on running at 4.3GHz which is requiring 1.2V to be stable. At these settings I am seeing temps of around 26-30C at no to very low loads and I am peaking at 60-62C under full load. My cooler is the H80.

When I get my 3770k I too am planning for 4.3-4.4 around 1.2v with sub 70c

With the Intel® Core™ i5-3570K and an Corsair H100 I was able to hit 4.8GHz at 1.25v but the temps were up in the 90c (Sorry this is all from memory). I ended up dropping down to 4.6GHz but still around 1.2v but this got me down into the high 80c. In the end I left it at 4.2GHz and 1.15v and I am going to try playing with the voltages some more to see if I can get them lower without any problems.

Feels bad, man. At what clock speed were you running your 2500K?

Unrelated: Tapatalk 2 sucks.

Tapatalk2 isn't that bad.

The last three comments I've posted from my smartphone have had big errors that I've only been able to correct on my laptop. IMO, that's enough for me to say it sucks. But I won't go off-topic, so back into discussing Ivy Bridge.

 

[Subyman]

Anyone have links or speculation on what kind of temps would be expected from a proper WC loop? I have an EX360 Rad and XSPC Raystorm waterblock on my 2500k right now, which is waaaay overkill. Wondering if IB would be ideal on my setup.

Ignore if I am too late on this. I just read this today about Gigabyte boards and Ivy Bridge Link

 

[LagunaX]

UD5H seems fine for those that have it.

My ambient temps are 30C on average and probably 3C lower on a cold night. WC setup is a XSPC Raystorm + XSPC EX240, with an EX360 you could probably deduct 5-10C off the temps I'm getting. Temps for a Core i5 3570K 1.295V @ 4.5GHz full Prime95/LinX/IBT load on average is about 70C+-5C. Assuming as such, my delta temps would be 40C and yours could probably do about 35C delta temp or less.

I don't have readings for anything higher than 4.5GHz as the voltage required increases exponentially anything beyond 4.5GHz for my chip. I would need about 1.410V just to boot Windows at 4.8GHz and BSOD almost instantly, not stable enough to do any stability testing.

So with these low overclocks do you Ivy Bridge owners think it was worth it from Sandy Bridge?

 

[Hippiekiller]

I7 - 3770k is what I got. Got it at micro center for $290+ Tax on Sunday.

Here is how i am running it. All that I did to overclock it was go in and turn the maximum turbo for every core to 4.3ghz. I had it running fine at 4.6 and didnt try to go any higher and didn't make any voltage adjustments. But, I decided on 4.3 as it felt so amazingly fast already.

4.3ghz turbo
1.15v is used when maxxed out in Prime95

I did not make any other adjustments in bios besides the 4.3ghz turbo setting. Am I missing something here? I like it like this cause i get the speed when i need it and then it is running at 1.6ghz when idle. Is there a point to over clocking the old school way?

I don't see why it isn't worth it. Core i7 3770K stands a better chance of getting higher than 4.5GHz with reasonable voltage. Has higher clock speed become a symbol of bragging rights? The actual yardstick should be how high of a score you could attain in a benchmark or how fast you could finish a task, not raw clockspeed alone.

 

[BTRY B 529th FA BN]

I would imagine when one is comparing apples to apples.

Man, I wish I could at least boot the CPU like you guys can! Consider yourself lucky

I took the Gigabyte Z68AP-D3 (rev2) board back and got a full refund. I'm just waiting for the refund to appear back in my account, and am going to get a real board this time. Too bad CompUSA (retail store brand of Tigerdirect) doesn't have any Intel 7-series motherboards in stock. I don't know why, but they're a good month behind in their stock availability. All they have are Intel 6-series, and I'm not about to toy around picking a motherboard that *might* have the latest BIOS installed. I live in Tampa, FL though, and there's not really any alternatives around other than the CompUSA on the other side of town. Maybe I'll call them and see what their stock is like.

Either way though, once my money clears, I'm going to be picking up this board:

Am I making a decent choice here you think?

 

[blackened23]

Got my 3770k. Requires 1.25V to boot at 4.6ghz, temps are high. H100 cooler, temps across all cores after 15 minutes of prime95: 74 81 78 76. By comparison, 2600k was around 60-65 at 4.8ghz.

Was hoping for a better voltage at 4.6. Back to testing, not sure if i'm 100% stable yet. So far, at the required voltage IB seems to be 15C hotter than SB at the same clockspeed on average when oc'ed

 

[LagunaX]

Consider this board too it is the top of the line Biostar board in the same price range:

I got mine. Running it at stock at the moment. HT is enabled.

Ambient: 25c
Idle: 26c-30c
Full load on all cores from Inplace Large FFTs with Prime95 after 30 minutes: 67c-72c
Cooler: NH-D14
Case: FT02
Motherboard: GA-Z77X-UD5H

On the plus side, between the 3770k and my new Seasonic X650, my power usage has decreased by a nice amount. The wattage was measured using a Kill-a-Watt which is connected to my UPS which also powers my router, modem, monitor, external HD, and powered USB hub.

Old Phenom X4 955 Stock Idle: 230

Wow that is even hot at stock speeds! Mine will be here tomorrow so we will see.
