Can anyone help me push a little further? Bios shots are below... currently using my machine at these settings but I BSOD x101 16 hours into Prime blend. Warning: Spoiler! (Click to show) (cliff's notes)
47x @ 1.385 vcore
auto vccio and PLL
ultra high LLC
extreme phase & duty control
PLL overvoltage disabled
I'm not happy with me temps... max is 68-75 across the board. Would love to lower vcore to get this 24/7 stable. I don't want to mess with C3/6 as storage speed is very important to me.
Any ideas? I figure my best options are to press forward by fine tuning PLL & vccio OR drop down 1-2x on the multiplier to run cooler/safer.

I decided to clock my machine down for the Summer. I've been running 4.8 with offset voltage since December. Recently, I was getting a BSOD every other week or so with a 1E error. There was never necessarily anything going on when I got the BSODs. I could be in a Word Document or Firefox, no gaming or anything at the time. I thought maybe my overclock was degraded, but when I checked the logs, I noticed that the last thing that happened before each BSOD was an attempted backup via WHS Connector. My WHS machine is not currently running, so I'm guessing that was the real reason behind the BSODs.
Anyway, I decided to go for 4.5. Via manual voltage with LLC set to Ultra High, I found that I needed a minimum of 1.256 vcore showing in CPU-Z to be stable for 16 hours in Prime 95. The VID was showing 1.3411 under load. It was really hard to get 1.256 vcore under load with any level of LLC while using offset voltage. The problem with Ultra High LLC was that I had to set offset to -.075. I would get the right vcore at load, but idle was dropping to 0.94 or so. I've heard that you can get BSODs when you're running that low. I didn't, but I wasn't really testing it for any amount of time. I went through all levels of LLC with the same problem. I could easily get the right load vcore in CPU-Z, but idle voltage was always sub 1.000. I eventually settled on LLC set to normal (AKA 0%) with offset of +.020. This got me 1.000-1.008 at idle and 1.248-1.256-1.264 under load. I was able to finish 16 hours of Prime 95 with this. However, I took the screenshot and left it running and I got a 3B BSOD a couple hours later. I noticed that it was running at 1.248 when I last looked at it. So, I've actually since changed the offset to +.025. The only downside I see to this setup is that under light load, voltage is hitting 1.304. Full load drops it down around 1.256 though. Enough talk:
Intel Core i7 2700K Batch 3138A726
BCLCK 100.0
Mulitplier 45
Offset vcore +.020
PLL 1.60
Duty Cycle Extreme
Phase Cycle Exreme
VRM Manual 350
CPU Current Capability 140%
Everything else auto/stock
Max Core Temps 59 66 66 64
Ambient temps from 25.4 to 26.4
Here's the proof and BIOS settings I used for the 16 hour Prime run:
I may have to try auto and see what happens.

As far as i know my system is stable .... I have been runing prime for the last 16 hours and it is really stable As you can see in the photos.. I want to join the club
One thing that i really want to know is if you guys think i can get better temps by lowering the Vcore . But since i am fairly new to this overclocking world i think i might be getting way over my head.
I used a very easy guide to overclock which i include along with the pictures.. Of course i used the simplest way .... and only had to change like 3 settings in the bios and i was done.
What do you think so far of my overclock ???? Do you think i can get better temos by lowerind the VCore or use something like DVID.
Thanks
Shremi

@ breenemeister - thanks for the suggestion. I lowered PLL to 1.4 in order to do a step-up test to find the minimum. No boot at 1.4, but I'm currently 1hr stable @ 1.5. My temps somehow seem higher than before (2-3 degrees). My ambients are about 65F/18C. Trying to decide now if I should bump PLL up to 1.6 and restart or keep pushing thru with the current test.
