Is your CPU stable on OCCT's Linpack @ Max setting?

[Studabaker]

Here's a stability test that I hadn't heard too much about.

Everything is stable on my computer except for this, it fails out at some point (so far between 15-25 minutes). It also drives temps ridiculously higher than Prime or Orthos at CPU burning settings will run, my cores were hitting 75 when Orthos CPU stress gets them to 63 or so.

I'd like to know if all those insane overclocks out there are as stable as the overclocker would like to think they are.

Linpack is designed more for testing your cooling setup than stability really. Its programmed to make insane amounts of heat. Its actually written by Intel themselves. I darent run it for an hour to see if its stable, lol.

 

[AllHopeIsGone1]

I'll stick to Prime95.

 

[newtekie1]

My 3.6GHz 24/7 clock is stable with LinPack. My 4.0GHz clock speed is not, though it is stable with everything else, LinPack is actually what made me lower the clock back down to 3.6GHz.

 

[Studabaker]

Hah, man! I bet Linpack would destroy most people's 'stable' overclocks!

 

[Urukland]

Linpack is the intel burn test . It put the heaviest stress in the cpu, more than any other stress software like orthos or prime. Not bad to know the limits of your cooling system, but i prefer run 8 instances of prime instead, because it test better the stability of ram. Sometimes a rock solid oc in linpack fails in prime95 in minutes.

 

[alexp999]

Where the hell does linpack find 3gb of stuff to shove in the ram??

Temps reached about 70*C (OCCT temps are wrong for my Q6600, they reported 80*C )

Nope. Just let it run for 30 minutes and it's still stable. Only 56c too.

Nice! Our specs are pretty off though. When I get a HAF 932 and a Xigmatek HSF I'll do the test at 3.6 and let you know how the E7400 pairs up to your PII X3.

 

[ShadowFold]

I've already owned an e7200, nowhere near as fast

hell no mine isn't after about 20min temp peaked to 92c and it failed how can it get that hot using a Xigy 1283 and MX2? my clock is stable for over 24hrs of orthos and ~2 weeks of folding and bonic so far

Try running Core Damage

Aha, so we have another. Those temp readings are probably off for you indeed, but wow, that's still hot even if you're getting temp readings off by 10 degrees.

Also, you've got a mighty OC + voltage on that little chip.

stock is 2.5ghz running 3.125(3125mhz) stock voltage for my chip is 1.18v running 1.36v

Try running Core Damage

almost an hour of core damage btw Nextsensor seems to read my temps the best Everest gave me WAY TOO HIGH readings so i don't think it got 92c or close to it 40c seems about right but nxsen doesn't read my v-core right CPU-z shows it 1.36v but that doesn't matter to me all that i want to know ATM is what one has the right temps

so hows this (btw this is 3ghz 3.125ghz wasn't stable for this test but is 24hrs orthos stable so i will set it right on 3.1ghz for 24/7

Yep, sure is. I don't run anything unless it's absolutely stable. That's how my video card died, running a slightly unstable overclock.

That's why I set my vid card back to stock. The 20-30 MHz OCs I get on the core/shaders/mem doesn't even do anything, it makes it less powerful if anything. Case in point I'll never buy another BFG card again.

 

[ShadowFold]

My 4850X2 goes from 625 to 720 pretty big jump

Don't worry, I am thinking there might be an ATI card in my future.

All my machines are linpack stable.

What kind of OCs, voltages and temps are we talkin here.

9450 @ 3.8Ghz sits in the upper 90's for linpack @ i think ~1.3vcore (could be less havent been in bios for a wile and its not fully tweeked)

Q6600 @ 3.4Ghz 1.38vcore under water loads in the mid 70's with linpack

Q6600 @ 3Ghz 1.35vcore loads in the high 80's under linpack

E8400 @ 4.2Ghz 1.35vcore loads in the high 90's under linpack

Not sure what the new quad will do though i doubt i will be overclocking this one.

 

[Mussels]

i ran linpack and only one core loaded. made me sad.

edit: oh yeah, it as "monitoring for a minute" and i hadnt quit CoH or portal woopsies.

There might be some incompatibility here, every time i run linpack my machine shuts down. Not resets, not BSOD - it turns off. Starting 7 back up there is no "windows has recovered from a serious error" or anything to indicate an actual crash.

I wonderi f OCCT is reading temps wrong and forcefully shutting down my system...

 

[silkstone]

I ran OCCT, at first it wasn't stable. There was something off on the temp sensors. It would jump to 80C and then stop! Once i got it working properly and reading the correct temps my comp was fine and stable

Probobly because your hitting the thermal shutdown for the CPU.
