NOTE: If you have Sandybridge (1155 socket), your only stress-test options are Folding@Home or Prime95, all other CPUs can use any of the 4 tests.[/I]

Sorry man but I have to hold the rules true for everyone. =/ I even had Uggor earlier trying to sway me and I had to tell him no. :P

Also, you need not add all the extra info. :P Just put the voltage down that you set the CPU at in the BIOS. idc what your offset etc are at.

Really don't think my thermal paste is spread or real temp is being gay as soon as a core hit 90c it dropped down to 75 1sec later

This is because you are running IBT with extremely small problem sizes / low memory usage. With each run lasting only 7 seconds, you aren't going to hit max temps for long before the cores get a chance to cool back down. Check my screenshot for a much longer run with ~6GB used instead of 1GB.

I think the H100 can squeeze out 4.8GHz @ ~1.5v with a push/pull setup and I learn to use all the other voltage settings.

CPU PLL is probably the only additional voltage based setting you need to mess with. Sometimes lowering it to 1.7V can help stabilize an OC at a certain core voltage.

Sorry man but I have to hold the rules true for everyone. =/ I even had Uggor earlier trying to sway me and I had to tell him no. :P

What's the reasoning behind this? Just curious.

[DeltrusDisc]

I actually just realized Wadoo wasn't using Max IBT settings. He is disqualified until he can show one using the proper settings outlined in the original post. Sorry I didn't realize till now.

@kidsafe - I don't know all the numbers and reasoning exactly why, but apparently IBT does not properly stress 1155 Sandy Bridge CPUs in the same manner as other CPUs, and sure it will push higher temps out of it compared to the likes of Prime or F@H, it still is not a strong enough test and good enough at testing stability on Sandy Bridge. I was advised not to allow IBT for SB by I believe Cilraaz, if I recall correctly, since he is a more hardcore OCer and thus someone I trust on the matter. I am looking into whether this is still the case or perhaps IBT was updated.

[kidsafe]

Okay, see you again in 8 hours.

[DeltrusDisc]

Yay I like people who are dedicated! :P

none of us in SB-E are using max settings, and i doubt any of us would rather bother

[DeltrusDisc]

How very honest, though that kinda annoys me. I guess I need to highlight that part in the original post. >_<

[kidsafe]

It would be unfair for SB-E to only have to pass ~2m of IBT. Not when I have to pass 8 hours of Prime95 blend.

Yer i saw that the other two SB-E did standard so I thought that was what you were asking for don't have enough time to leave my PC doing an 8hour burn test more then once

[DeltrusDisc]

Yeah sorry. =/

Me too...I just used the same IBT settings as Cyanotical did when he posted his result. Time to do a F@H test then.

um no, most 24/7 stable lists/clubs want 12-15 hours, not 8, and if there is an issue, it may take a while to show itself with prime95, meaning you could have hours of CPU degradation, not exactly something im interested in with a $1000 cpu, a $180 2500k is not a big deal if it fries, nor is there reachable thermal limitations on it like on the SB-E chips

*Shrug* Your $1000 SB-E will be the functional equivalent of a <$200 part in roughly 2 years. For a $35 premium, your i7-3960X can also be covered by the Intel Performance Tuning Protection Plan. I agree 8 hours is not a guarantee of stability...that requires an uptime metric on the scale of years, not days.

Find the point at which Prime95 crashes immediately. Add .01V to your CPU voltage. Run again...if it crashes in under an hour, add .01V again. If it doesn't crash, try to leave it running overnight. Finding the proper CPU voltage shouldn't take more than a couple of nights.

Well you have other tests available to you, since your chip is not just a Sandy Bridge chip. You could use F@H. ;p

Which I'm pretty sure you do anywaysssss.

16 hour P95 test, nice kidsafe! Added!

[kidsafe]

For Sandy Bridge + Asus mainboard owners, you can adjust CPU voltage a third way in addition to Manual and Offset Mode. In the CPU Power Management sub-menu is a setting for Additional Turbo Voltage. Basically this is an offset that only gets applied to turbo multipliers and it works great in conjunction with the normal Offset Mode and higher LLC options.

For example, to achieve 5GHz (w/HT off), I'm looking for 1.432V under load with Ultra High LLC. For my particular board this can be achieved a couple of ways.

Offset Mode of +0.065V results in 1.432V load and 1.064V idle.
Offset Mode of -0.035V and Additional Turbo Voltage of +0.136V results in 1.432V load and 0.976V idle.

Additional voltages needn't be messed with, but some people do bring them down slightly to reduce overall component temperatures. I see no issue with running the following settings:

VCCSA   0.925V->0.900V
VCCIO   1.065V->1.000V
CPU PLL 1.800V->1.700V
PCH     1.050V->1.000V

Yeah I overslept a bit, then went out to lunch before stopping the threads. I'm actually experimenting with a 5GHz OC now, but HyperThreading is disabled.

[DeltrusDisc]

Well you have the cooler to do it best with!

thats not my point, if i was using an i5 i would have no trouble pushing into the 1.6v range, because if it fries i can get it replaced in 20 minutes, i live near a microcenter that always has them in stock, if i fry my 3960, im out a CPU for at least a month

[kidsafe]

I have multiple PCs (and Macs) to use as spares and I'm sure you have a spare PC or two.

Updated initial post with the following new requirement in desktop SSs.

As of February 13, 2012, a new requirement has been put in place: you must also have your MMO-CHAMPION.COM USERNAME listed in a text box in the SS as well!!!
