Ivy Bridge Lowered Expectations Club

[utahraptor]

Yes I admit I thought my 3770K would be special and would run 4.5 GHZ with no problem and run cool with a Corsair H100.

The reality is I can't get really get past 4.3 GHZ on all 4 cores at 1.29 volts.

I do run with turbo so with less cores I pull 4.4 GHZ.

The Corsair H100 sounds really bad on medium or high settings. It is not the volume, but rather the frequency I think that makes the sound terrible. Even when the cpu is idle it sounds bad on medium or high. No sound or grinding or anything, just bad sound.

I tried to do 4.5 GHZ full time, but I had to keep pushing up the voltage and the temps were getting really bad with the required voltage.

Another strange thing, with my mother board set to the following turbo multipliers : 43, 44, 45 45 I NEVER get 45, even with a single core loaded. I don't know if it is a design defect or what, but the only way to get 45 multi is to set every turbo bin to that speed.

Anyone else get a turd of a chip?

What kind of temperatures are you seeing?

Also, something doesn't sound right. My i5-2500K hits 4.4 GHz on 1.3v fairly easily. Your CPU should go at least as far at that kind of voltage. I know every CPU is unique, but unless we both have some kind of crazy outlier, something isn't right.

 

[Yuriman]

I have the same experience with the multipliers.

What are your temperatures? You may find that due to thermal limitations, you might be stable with a lower voltage.

Also, your chip may require that you enable PLL overvoltage to get a higher frequency. Have you tried that yet?

Another user posted here a few days ago with a bum 3570k, he seemed unable to get even 4.3ghz stable. So far as we could tell, he wasn't doing anything wrong.

EDIT: My experience has been generally positive with Ivy Bridge. My chip seems pretty middle-of-the-road - it will do 4.6ghz with around 1.29v but I'm not comfortable with that on a day-to-day basis as it hits 100c in LinX with watercooling. I think the chip itself is a good overclocker but the thermals seem particularly bad, a good candidate for delidding.

I think you could list all your equipment .each ib mb requires different setting as the programers made up different names for most settings.

-ocing ib is tricky with the way they set up the bios,-I like you keep on adding more vcore at one point to try to get prime 95 blend stable @ 4.6

-only to catch on prime only had problems with the ram stressed in blend not in the other torture tests , as I under clocked the ram down to 1866 [ram auto set 9,9,9,@ 1.63v] until I had a stable cpu in prime 95.

I did not think ram that was underclock that much would fail and would cause the system to be unstable. it had passed memtest+ at stock speed[2400 10 @ 1.65v] before 3 x bios updates , so I just under clocked it to set the cpu again now that the new bios had stopped coming.
-but when I set the Ram's xmp which is 2400 10 @ 1.65v and it pasted prime 95 blend easy with .020 less vcore.

I doubt you have a bad chip , only a bad bios set up.

I have the same experience with the multipliers.

I have strange multiplier issues with a 2600K on a P67 motherboard. With the previous 2500K I could do 45x fine for 4.5GHz. With the 2600K setting 45x results in... 44x. Setting 44x results in... 44x.

 

[masterxfob]

i can only hit 44x with 3570k and asrock z77 x4

This is my reaction to Ivy :

That piece of crap was not stable even at stock speeds.

Tried it on three different motherboards, with four different (expensive) power supplies, at least five different types of ram, and with various coolers and diamond thermal paste (grain of rice size) ranging from the stock cooler just for giggles all the way up to my H100. It would push past 50C in the BIOS, usually freezing in the Bios (again, THREE different boards), and it never once saw a Windows desktop, even with trying undervolting and slightly overvolting (only 100mV) with the H100 in place.

In more than 25 years of working with literally hundreds, or more probably thousands, of Intel CPUs, I've never seen one this bad out of the box. It was a totally unusable piece of garbage, and it wasted my time.

This was a new build for a customer who is fairly important to me, so after explaining that Ivy is basically a very minor tweaking from Sandy that has some drawbacks, we got a 2700K in there, and it's running 4.8Ghz under a 212 at very reasonable temps with only a tiny voltage bump. On the same initial board with the same initial ram and the same PSU.

So yeah, I'm done with Ivy, and I won't be recommending them to anyone, unless it's a notebook with a warranty, or a cheap desktop that won't be overclocked.

I bet Intel does better, much better, with Haswell. Every once in a while they have a dunce moment, such as the P3 1.13, or Prescott.

Why the rant? Replace the CPU and be done with it! Based on the pic you posted, I did pretty much the exact same build a week ago for a family member. Worked great, and I only had a CM 212+ cooler. Got the 3570k to 4.2ghz, and it only maxed temp around 80C with both the CPU and GPU stressed. Worked great with only a slight voltage bump. Couldn't be happier TBH.

Well, the rant was because out of several dozen Sandy builds, not a one gave a lick of trouble, other than a DOA PSU that was promptly exchanged.

Besides, 4.2Ghz? I don't care if Ivy is slightly faster clock for clock, when it's more expensive and doesn't reliably clock as high unless you de-lid it.

I think they only make sense for :

Nuts who delid.
People who never overclock (admittedly, this is a huge market).
Notebooks.

Apparently 4.5Ghz is the common limit on decent air cooling for 3570k/3770k, yet I don't seem to have trouble getting 2500k/2600k/2700k to 4.8-4.9, so it's kind of a wash.

I guess I'm cranky because I almost refused to believe that the thing was defective, and wasted a lot of time confirming it. It's more a testament to how good Intel usually is that a rare bad one would make me so angry.

 

[WhoBeDaPlaya]

+1 I was not enthused with the 3570K I got from the MC here in Dallas. 4.2GHz max with sane temps under a CM 212+ w/IC Diamond. Coming from an i7 920, I was sorely disappointed (4GHz @ 1.152V).

Changed it for a 2500K. Once I get a damned (probably mobo) issue ironed out, I'm looking forward to OCing it.

On the bright side, Ivy produces noticeably less heat under load, and that's important due to my cramped living space. It's the difference between an unpleasantly hot room when gaming, and comfort.

In all probability your GPU puts out substantially more heat than either anyway. Unless you're not a gamer? Neither Sandy nor Ivy, even overclocked pretty good at boosted volts are anywhere near a high end GPU, or oc'd BD for that matter.

I also think some of the reason Ivy puts out less heat is because less is effectively transferred from the die to the IHS due to lower quality TIM (proven by the de-lidding folks).

Not saying that a hot PC isn't an issue. I have a CM Storm case, 750W PSU, GTX 670 FTW (stock), and a 2500k currently at 4.9 (testing my H100), and I can't feel any heat coming from the case. But my PC is in a large room that's well ventilated, so my ambients are low anyway. I can relate to not wanting a flamethrower in your room if space is an issue.

 

[utahraptor]

What would be a good starting point for taking the PLL voltage up?

 

[WhoBeDaPlaya]

As I understand it, people recommended decreasing the PLL voltage for IB overclocks, not increasing it.

 

[Yuriman]

"Internal PLL overvoltage" is a different voltage from PLL voltage, apparently.

Depends on your chip.

My rig has no problem heating up my room to over 80f. (Without stressing GPU) I wouldn't call Ivy a cool running chip by any means.

 

[IntelEnthusiast]

I am sorry to hear that some of you seem to be having a problem with the 3rd generation Intel® Core™ processors. When I built my 3rd generation system with the Intel Core i5-3570K, Intel DZ77GA-70K and the Corsair H100 for cooling I was stable at 4.6GHz but temperatures were up to around 90c in LinX.

If your processor isnt running stable at stock speed give our technical support a call at 916-377-7000 and they will be happy to see if they can help you out.

 

[UNhooked]

Well at first I was bummed that I didn't get Ivy for my new build but threads like these make me happy that I went with the 2700K chip and a Z77 mobo.

I think Ivy is a great option if running stock but for the OC community I think Sandy is still king.

 

[Idontcare]

Anyone else get a turd of a chip?

I would consider my 3770k to be a "turd of a chip".

Lapped my i7-3770K and there was zero improvement in operating temperatures!?

However, delidding it and replacing the "turd of a CPU TIM" definitely made lemonade from those lemons.

Delidded my i7-3770K, loaded temperatures drop by 20°C at 4.7GHz

Yes but delidding needs 'cajones'

Not each CPU is equal.

 

[Termie]

I'll admit there's a wide spread in quality of the Ivy chips, and if Intel is concerned about overclockers, it should look into why Ivy is so unpredictable (TIM, perhaps)?

I've been very lucky with my chip. Runs 4.4GHz at stock volts (mid-70s C in IBT), and 4.0 undervolted to 1.05v (low-60s C in IBT). This is with a lowly Hyper 212+, beefed up with dual Scythe Kama Flow 2 fans and some MX-4.

I also got extremely lucky with my old e8400 (3.6@1.2v, 3.3@1.1v), and less lucky with my current i7-860 (limit of 3.25@stock volts). So there's always going to be some luck involved, but Ivy definitely pushes those boundaries.

 

[BenchPress]

I bet Intel does better, much better, with Haswell.

What are you betting on? Running stable at stock speed, or running stable at a high overclock?

They're increasing the number of arithmetic execution ports from 3 to 4. Last time they've increased it, going from Pentium 4 to Core 2, the clock frequency was dropped significantly. Of course that also included a healthy reduction in pipeline stages, and Core 2 ended up being faster. But Haswell might end up performing only slightly better (for scalar workloads), at lower clocks to reduce power consumption. Of course there's still mighty AVX2 and TSX to look forward to.

I'm still hoping they found a way to eliminate the downsides of widening the architecture, but I wouldn't bet on it. Haswell may not be an overclocker's dream. It should do great in ultrabooks, All-in-Ones, and perhaps even tablets though...

 

[rgallant]

my take on ib coming from x58\920 is that the mobo makers failed on the bios ,their take on it even from RAGA[asus] IVY B OVERCLOCKING GUIDE is that there is so much info on sb over clocking we'll skip that and go to the 30 x ram sub. settings.wgaf

-there might be 5 settings in the z77\ib to change for a stable 4.6 oc but the idiots mixed them in with 30 other useless settings. enable\disable something on one page and it makes some other settings\menu change in a different section\page.

I would say when sb came out my 920 bios was way more stable than a sb bios having been tweaked over the years , so users coming from sb to ivy would find sb easier as most bios's are from z68 and only tweaked before being added to the z77 mobo's.

http://www.overclock.net/t/1291703/ivy-bridge-overclocking-guide-asus-motherboards
is a fairly simple guide to overclock ib and will get you in the ball park of 4.6
-and for those using a $20.00 cooler on a $1500.00 build what can I say.

 

[utahraptor]

I may try to adapt the guide to my gigabyte board. I did not realize that the BSODs could give specific codes
