Dolphin (emulator) - the best stability tester

[HeXen]

looks like someone doesn't plan on keeping that mobo for very long. Oc'ing can be fun n all, but maintaining high stress, stable and cool or not, shortens the life of hardware, sometimes really short. i've lost many mobo's from OC'ing with liquid coolers, 240mm side case fans, even at one point used 7 120mm fans. only had ram sticks fail on me a couple times, most high end ones seem to last pretty well.

main thing is, the performance difference is mostly just benchmark numbers. Getting a small few FPS in games or a couple milliseconds in some apps is hardly worth the bother to me anymore.

 

[cmdrdredd]

Wait... 4.5Ghz at 92c????

You sir need some better cooling

What? You're not stressing the motherboard at all. You're using the CPU multipliers which are provided by Intel to make the CPU run at a higher speed than stock specifications. The motherboard is only applying small amounts of voltage and not running beyond stock speeds.

Unfortunately cooling doesn't get much better without a TEC or phase change. I have a Swiftech block, Laing DDC pump and a good triple rad, the base of the waterblock and the water don't even get warm and my mount is fine. I'm guessing this chip in particular is just warm for Ivy - perhaps the thermal paste under the lid is especially poor or something. Either way, the temps don't hinder my overclock.

 

[exar333]

I am doing 4.6ghz on air, with 2 more cores and still cooler. D@mn IB is a hot CPU...

 

[cmdrdredd]

Really? I'm running air and for $80 I don't even touch 75c when running linX. I bet if you ran IBT you'd throttle. IBT only runs up to 81c for me.

Something is very wrong with your water setup that's for sure.

 

[Subyman]

Wow, my SB 2500K at 4.4Ghz with 1.35-1.38V only gets to 45C under massive load with my loop. I'd say you need to back off that voltage and be happy with a lower overclock. You are asking for trouble running that daily.

It's not the voltage (which is below stock/at stock levels) and it's not the clock speed.

I have the same CPU except I'm on Air and am never seeing above 75c in LinX. There's just something with his water cooling that isn't quite right.

I don't know why you guys think temps you get with Sandy CPUs are relevant at all. They really aren't, we all know the thermal properties of Ivy Bridge. On water, with temps you are getting I wonder why you aren't overclocked way more. Also, do you really need 1.38v for a 4.4Ghz clock speed?

I thought that might be the case too when I first installed it. I moved the loop intact over from an overclocked Q6600 which was running in the low 50's LinX loaded (which was good for that chip), and saw those temperatures (90+). I remounted (paste application looked fine) to no avail, tore the loop down and cleaned it and remounted again still without a reduction in temps. My idle temps are great - just above ambient for all 4 cores. Under load, the waterblock doesn't get noticeably warm either, and I have good reason to believe my mount is fine. The only conclusion I can come to is that my chip is probably a good candidate for de-lidding.


Perhaps I should lap the chip and block too?


cmdrdredd, what program do you use to report temps? What exact voltage and clocks? What is your Prime small fft highest core temp, an your LinX highest core temp?

In my Bios I set +.011 offset with LLC off, CPU PLL voltage at 1.7125. I use realtemp to check core temps. Highest LinX temp is 74c, highest Prime95 SmallFFT is 77c for a second then drops and settles at 75c-76c.

CPUz reports 1.248v.

For whatever reason our prime temperatures aren't far off but LinX warms my chip up about 15c higher than yours. Are you using LinX 0.6.4, as linked at the top of the CPU forum in the stability testing guide?

 

[cmdrdredd]

Of course I am. The temps vary a bit between runs but those are pretty much what I'm seeing.

IBT is of course higher

Intel Burn Test and LinX are the same, aren't they? I assumed they were since my temps are about the same in both.

The performance difference really depends. As Things get more demanding, overclocking can give very tangible benefits. Particularly if you arent running the latest and greatest. I had a Q6600 before my current system that was overclocker to 3.2 GHz. There were a couple times it reverted back to defaults due to power outages and I felt the difference as soon as I loaded my first game and it was a huge difference. If for whatever reason I couldn't overclock and was stuck at 2.4GHz I'd have upgraded at least a year or two sooner than I did. And that OC was stable through the entire 4+ years I had it.

My last stability issue only happened when idling or web browsing...either upping voltage or decreasing the clock speed eliminated it. Playing games or running benchmarks or prime didnt cause any problems. Explain that one. That's why Im not really one for stress tests. Sure I'll run prime for 5 minutes as an initial test, but I just do my normal stuff and go from there.

You had LLC enabled didn't you?

No offense, but you will never find true stability with a mindset like that. Wouldn't you hate it if you were doing something important and lost all of your data, or time spent on that project etc. It's annoying when that happens and to eliminate that, we have stress testing programs. P95 should be ran overnight and IBT/LinX should be ran for a MINIMUM of 25 loops, I recommend 50-100 though, WHILE WATCHING TEMPS. You can still web browse etc, just don't expect to do any heavy lifting while p95/ibt run.

For comparison sake, they are certainly relevant.

If you use C states and speed step to drop voltage during idle it is possible the voltage was dropping too low for idle speed. People using negative offset or very small positive offset sometimes experience this.

For comparison sake, they are certainly relevant.

Only if the user is running a sandy CPU. We've covered this in many threads and even in articles here on AT. Ivy bridge is simply going to show higher temperatures. So when someone says "my 4.7Ghz 3570k is running 90c at 1.38v is this safe or should I think about dropping clock speed to keep voltages down?" and someone comes in and says "oh well I'm running 1.43v at 5Ghz and my 2600k doesn't hit 80" That's not helping anything at all.

Comparing apples to oranges is never relevant.

Those extra couple hundred MHz aren't worth suiciding the CPU.

Well, I'm still going to repeat myself. I am running the same CPU, same clock speed, same voltage and I'm getting 10c+ lower temps. He's on water, I'm on Air!

So...what's the deal with that? I find it hard to believe that his CPU is that much worse.

If he can get the temps under control that's great. If not, then he really should aim a bit lower.

 

[Martimus]

He may have hotter ambient temps as well. Although thinking about it more, that wouldn't account for a 10C difference. You probably just have a better chip than him.

 

[cmdrdredd]

it has the same stepping codes (according to cpu-z).

It's just really odd. I'm also in Florida where it's been consistently in the 90s lately and the temp in my computer room is about 78-80

cmdrdreddm, what are your IBT load temps? Mine are identical to LinX at ~88-90c on the hottest core.
