Dont have an i7 anymore, but yes, thats as low as it went. Voltage was read with a DMM, CPU-Z reports it WAY wrong.

Also, you are testing partial ram in that pic, not all. Makes a big difference in stability.

As far as the voltage that I can't argue about as I did not read them with a MM, but the RAM, was used about just over half, and then these settings also primed for 5 hours that same night, and went on to crunch at 85% for about a day and a half after. So I'm pretty sure it was stable. But regardless I'm not running those clocks now anymore, I'm on stock cooling so down to 3.6 GHz @ 1.094v. I miss my watercooling! "hung:

What Cecil was getting at is, when running LinX to test stability, you should run 20 passes and remember to press the "All" button beside "Memory to use". Itadds quite a lot of stress.
I've had runs crash in the 19 pass, 70+ min in.

I completely understand, but keep in mind I ran prime for five, I would like to say almost six hours that night and it didn't fail. I do however completely agree to what you guys are saying.

Prime really does nothing to i7, doesnt matter how long you run it when its not fully stressing the system.

If you run 8 threads of it, it'll stress all cores to 100%, did a quick run just to show you, see below:

Task manager will say 100% even when its not. The memory controller is on the chip, and prime does not stress it fully. Even 3dmark will say its 100% when its not. Thats why there is a large difference in temps between the tests.

I never noticed that, thanks for pointing it out. Prime is still to me the best method of stress testing based on my experiences. If you can overnight prime with no issues, I say you are good to go. LinX is great, but I've had LinX stable rigs fail prime. So I try to stick to prime unless I'm just looking for quick stability.

Meh, everyone's definition of stable varies. For me, if it runs wprime 1024, superpi32m, all the 3Dbenchmarks, and my fav game of the month, then its stable. I'm not crunching, folding or running a cad system so this works for me in my world.

I used to be that way, but eventually it used to come back and bite me maybe 3 months down the line. I do crunch 24/7 with both of my rigs though so yeah, just stop crunching for one night, test and if stable, crunch happily ever after :D
