Ivy Bridge i5 3570K/i7 3770K batch and o/c results

[tool_462]

Hey guys when I look at CPU-Z it shows my voltage as 1.248. I have it set at 1.35 in the bios. Is this normal or am I missing a setting? Also on load with P95 it drops down like 1.2?

What is your LLC (Load Line Calibration) set at? Try High or Extreme.

[Trice]

I had it on Regular. Put it to Extreme and it shows 1.248 and goes to 1.192 under load.

Is there a different program other than cpuz that will show accurate voltage? Or am I missing something in the BIOS?

CPU-Z voltage will be as accurate as anything else.

Are you setting the voltage to Manual or Offset?

I don't know how the MVExtreme BIOS differs from the MVGene but I can't imagine too much...so I should be able to help.

[Trice]

Its on manual.

[Trice]

When I put TurboV EVO to 1.185 it shows 1.296 vCore.

So stupid, and I still put BIOS to 1.3 and it doesnt "stick"

Testing Imc all air, all default vcore on MVG

3770k (diddled+liquid pro) h60 (upgrading to h100i) soon
gigabyte z77ud5 mobo
corsair vengeance 1600mhz cas9 mem

corsair ax850 watt psu

Im at 4.5ghz fully stable but i need 1.32v bios to keep stability with (extreme llc)
if i lower by 0.010 i get bsods my max temp 82c (only with fans at low)
I have tried going to 4.6ghz but even with 1.4v bios its not stable am i doing something wrong or have i hit the max clock for my cpu seems like i got a poooo cpu by your results

thanks guys

It looks like you have solid gear though you may have just an average chip. My current 3770K can do 5G at 1.37 solid on water with the lid on. What is your VCCSA and CPU PLL voltage set at?

the only volts i have touched it
cpu v core 1.33(bios)
pll volts 1.60 (bios)

everything else is auto
hwmonitor has vcc at 3.36v
hope that's what your wanting not sure how to find what it is to be honest

the Thread still dead?

3570K Batch L247B677 4.5Ghz with 1.088V

[tranceaddict]

Here is the 4.8GHz at 1.245V Prime SS.

Just an update. As the temperatures rose here to high 20C, I had to up the Vcore by 0.025V to be fully stable. Interestingly, prime was still stable but BF3 started to crash, and in Event Viewer I isolated the cause to the CPU. This just goes to show that even though it's prime stable, it might not be 100% system stable.

How is your IMC?
I have a similar batch, L247B700, it's good with 1.170v loaded (DMM) for 4.5g. But seems to need a lot of vtt (1.141) just for 1300mhz memory @ CAS11, Cmd rate @2T.

What is your CPU PLL voltage? I've read plenty of stories where the CPU PLL voltage has been set too high and actually limited maximum core speed. Try values of 1.65v and 1.75v, one of those may see you able to increase your CPU clock and decrease your vcore, 1.32v just for 4.5GHz is a lot for a IB. Its probably also worth your time to delid that 3770k, clean off the stock TIM underneath and take off the black rubbery sealant stuff. Doing that should see your load temps decreasing a good 10c, maybe more, and may also be another avenue to explore in order to lower your vcore.

i5 3750k 3234C407 Anyone know if this week is good?

[Ket]

Currently testing a i5 3570k, seems like its a pretty good chip as it will do 4.5GHz @ 1.12v or less. Will report back with screens after more testing.

[sepol]

I bought a new i7 3770k, Batch 3227B508. I'm using voltage offset. The voltage with 42x multi is almost the same as with 45x, 1,32V.
Is this normal ? The fact that my motherboard is a MIVG-Z, Z68 and not a Z77 can have something to do about it ?. Or it's just an averege chip with bad voltage regulation ?

[Ket]

1.32v is pretty high for 22nm really, what are your load temps like and have you set a relatively high LLC then tried lowering vcore? The fact you are using a Z68 won't make much difference either.

At 4.5ghz my hottest core tops 95?C. I know it's too much, like my vcore is. I use 50% LLC and a offset vcore of 0,005. What makes me think that I have a bad board is that the Vcore is always the same, independent of the multiplyer, with the same offset of 0,005. Always 1,32V, 1,35V.

[sepol]

I found out that with the 2600K it?s the same on bought my boards. Voltage is always 1,32, when LLC is at 50% and offset 0,005, independent of the multyplyer. Faulty Bios ??

[Ket]

Use fixed vcore instead and try 1.2v, it would also likely serve you well to delid your 3770k, time and again people have shown they shave off at least 10c by delidding, applying your own TIM then popping the IHS back on top. The issue with the 3770k and 3570k is that the black sealant doesn't allow the IHS to properly make contact with the core, which is what gives rise to the horrible load temps the instant you try to OC. For reference my 3570k which I have delidded, cleaned off the black sealant, used some Arctic MX4 then just sat the IHS back on top of the CPU now has a max temp of 67c on its hottest core fully loaded with boinc @ 4.5GHz 1.12v. For me going faster than that requires quite a voltage bump, even 1.175v doesn't allow 4.7GHz to even be marginally stable so given IBs tendency to heat up easily 4.5GHz has to do for me, not that 4.5GHz is anything to sniff at you aren't really going to see the difference between 4.5GHz and 4.8GHz or even 5GHz in 99% of cases.

What method did you use ? The Razor or the Hammer one ? Everybody talk about Liquid Coloboratory pro. What I have here is chilly factor 3 Tim, I think it will do, at least as an experiment.

[Ket]

I used the "gentlemens touch", which is the razor method with a slight twist. I don't pry the IHS off I just stick with the thin razor and cut around, it only takes a few mins longer and minimises the possibility of damage. For sake of experiments I decided to increase vcore to 1.2v on my delidded 3570k and shoot for 4.7GHz again, all seems to be well right now, but temps are about 10c higher.

4.5GHz > 1.12v > max core temp 67c with the CPU fully loaded running BOINC
4.7GHz > 1.22v > max core temp about 78c with the CPU fully loaded running BOINC

The question for me (and this will apply to you as well) is do you run the extra voltage for +200MHz? The only real reason for doing so would be for epeen as real world applications you aren't going to see the benefit of that +200MHz. If you are really hellbent on max speed then as I will likely do investing in the services of a NZXT Kraken X40 would be a wise move, although for a cooler it is pretty expensive really.

I'm looking for a great clocking chip on air or water. has to be do atleast 5.0ghz and must be 3770k anyone willing to sell or help me find it?
