Core i7/X58 Overclocking Thread

[ReverendMaynard]

And with that I bow out of this divergent conversation confident that this statement alone has proven my point. Being a scientifically minded person (or so I'd like to think) I cannot accept this criteria as proof, as it is based more on coincidental data and emotional response than it is of a reproducible test scenario designed for our purpose.

That having been said, it's obvious that you folks who do clearly understand that the criteria is undefined, and you are comfortable with that. I cannot fault your choice, as it is your own to make.

Hoping that I have in the least raised food for thought, I apologize for the divergence.

Todays overclocking is about as scientific as taking a dump. Sometimes it's easy, sometimes it burns and sometimes nothing happens at all.

[Splave]

if you need to be 40 hours prime stable for your computing needs, you probably shouldnt be OCing in the first place

Thanks for the great visual...I could've done without that.

It does take some scientiffic understanding to do this though. We do mess with electricity, and alot of test our PSU's, and check voltages, and we have to follow physics principals to do it. There is a bit of science to it.

[vikingboy]

if you set linx to use all available ram it creams prime for stability.

thanks for she info will try it too. Do i need to run two instances or is one actually able to fully load a 920?

[JWMc]

I don't think it's running Prime blend long term that causes the crashes. Isn't it more likely specific tests that it's doing? I got crashes right after an hour in 3 times in a row now as I'm raising VTT and it's always on the same test.

My thing is, I'm asking the system to do pretty tight timings with a big increase in BCLK. There may be specific memory bus loads that consistently cause blue screens and I don't want my system to randomly crash because of my bad settings.

What kind of VTT are you guys running with triple 2 gig modules in the area of 8-8-8-21-1T @ 200 BCLK, 3200mhz Uncore or higher and 3600mhz QPI?

Unfortunately I've spent all of time so far on dual channel and I'm just now getting my ass around to triple channel so I have no frame of reference for common VTT requirements at a given OC yet. Time to dig through some screenshots and posts some more.

you sir are very welcome lol.

You know what I mean though. Overclocking 8 or 9 years ago called for allot of dinking around. Today, we have so many methods of data backup and recovery, with cheap massive storage, flash drives and imaging techniques the need for anal levels of stability just isn't as critical as it used to be.

Sorry to drive the subject into the ground, let's get back to the results

[dejanh]

Bottom line is this...and I'm pretty sure I said this before too...

If stability is mission critical to you (a) you should not overclock and (b) you should not be buying off-the-shelf desktop chips

MRI Tech to Systems: "Hey, what are you guys doing here?"
Systems: "Dude, we totally overclocked your MRI scanner and it's 2x faster now! No need to thank us "

You'd never see that...

In that case I'm certainly glad I have nothing to prove to you

Yep, I can attest to that. Tape backups were good in their day, but they were painfully slow. Now, backups are not an issue.

I don;t mess with MRI's, but I do mess with Rcoket Data that is irreplaceable. I don't worry about my OC's becasue they are tested stable...stable enough that with my backups they don't matter.

Basically I do both. I do some mission critical stuff but small errors if I were to ever get any would not be an issue. Actually they wouldn't be an issue on an MRI either. They'd just do it over again. My Mother has actually had to have an MRI done over again becasue of a defect in the image, so even those machines are not infallible.

A chip

[YukonTrooper]

Let's see some longer runs, Roller. Five minutes isn't really indicative of much.

woah that's way better than my 920 3836A756!, what is your full batch number again ? It's for this thread http://i4memory.com/f55/i7-920-batch...e-share-13570/

[SteveRo]

I think this is the best I can do "ht on" at 21 cpu multi - keeping all voltages within intel specs (on water) - over night prime run - 9 hrs prime stable -

[Khalmyr]

Man I get so sad when I think I got one of the worst clockers around :P 3838A

People doing 4Ghz with 1.3v or less when mine requires 1.42v, and the heat output is so massive by then (low 80's) that I can't run Prime for too long

OC on mission-critical machines? Yes please!
You sure you're in the right forums?

Sorry mate, had a real good laugh when I saw this... 1,52V vcore being within Intel spec? Not even close
Nice OC anyway

Intel's max is 1.55v....plus his temps are beautiful.

[jcool]

Well on my box it says something about 1,3xV max as with the C2D's

.80 - 1.375 is the voltage range...that has nothing to do with maximum voltage. There was a page straight from Intel floating around here that showed the max voltages. I'm positive it was 1.55v core and 1.35v VTT.
