Ram did 4 passes of memtest okay. I upped PCH, PLL and VCCSA to the edge of white, running blend test again if this doesnt work its really gonna suck.

Fixed it, had to set up digi+ settings for the RAM, must of been getting vdroop.

gonna see if it last through the night for stability thumb.gif

I'll get it out of the way now, but people are going to tell you to stress using 27.7 as it introduces the AVX FFTs to the stress test, and should give you a better picture of stability. It draws more voltage to do the AVX tests.

No one here has any AVX software besides Prime and Linpack. Testing with them will only make people lower their clocks, or state max load Vcores that are way beyond real-use voltage.

Go ahead and get familiar with 27.7, but it's too much for 99% of people's setups here.

So for overclocking I just change multiplier and set voltage accordingly, and that's it?

What do I do for vdroop, LLC, and PLL?

I'm trying to figure out what ram kit to buy to pair with the 3770k I just ordered. I'm trying to figure out if any of you guys who are running 4.5ghz upwards are using a certain brand or not but its hard jumping around 15 pages. I'm also thinking of either going with the asrock extreme6 or the fatality z77 professional but totally undecided on the ram.

I can't decide between the boards. How important is 16+8 power phase design vs. 8+4? I'll be water cooling everything including the mobo if I can (cant find any chipset blocks for any z77 boards) and I want to run the highest OC I can. I also have a rx480 and ordered a TJ07 which is on it's way, this is going to be a fun build biggrin.gif

I know Linux, which tends to be finicky about running/installing with unstable overclocks, works perfectly too.
I think too much attention is being put on these WHEA errors.
Also, to whomever was referencing the chart for what temps they are supposed to be getting, you're interpreting the chart wrong. It was simply to show that not just voltage, but frequency is completely relative to temperatures. That it's not just the fact you're running 1.3v that's making the processor hot, but the fact you're trying to cram information in and out of the processor at 5ghz that's doing it. It was Sin's way of illustrating how tri-gate influences and how sub-zero can/will perform really well with these chips because of that.

the WHEA errors are definately to do with internal CPU errors that are recoverable - and it means the CPU is not fully stable/and or performing at full performance

for instance with a Handbrake encode at 4.6 - 1.275V (note was LINX and Prime95 stable (latter 7 hours) - I was getting WHEA 19 errrors every 1-2 minutes

at 1.29V one WHEA error every hour or so

at 1.305V every 2 hours or so

1.31V none so far ...

you can tell they effect performance, as if you are just fast enough to be stable running LINX and getting loads of WHEA errors you will note your MFLOPs in LINX are lower than they should ... and its repeatable

I've seen say at 4.6 at 1.27V down to 96, repeatable (and stable in LINX) yet bump Vcore to 1.305V and LINX scores go up to 104 ...

why is this ? well every parity error the CPU is doing a re-calculation ,yes its still stable to windows and applications but the processor is slower than it should be due to these recalculations

yea I've been told, and I appreciate your input.

I'm not the type that 24 hour stress tests and what not the machine is used strictly for gaming and I never play a game for more than a few hours at a time.

Until I get heavily into folding or whatever, I'll stick to regular prime and at the most like 8 hour sessions. If it passes that, its more than worthy in my book. thumb.gif

I would recommend some G.Skill RipjawsX/Z that have a XMP profile of 1866mhz speeds or higher. The Trident X ones that were just released also seem tasty as well. On a sidenote, OC'ing RAM is actually quite easy on Ivy Bridge, so there shouldn't be much harm in doing so if you want to get even more juice out of it.
The ones that I bought (http://www.gskill.com/products.php?index=462) are currently running at 2410mhz, with timings of 10-12-12-35-1T. That's really not bad seeing as they were originally intended to run at 1866mhz smile.gif You could also go for the Samsung Green kit, as they are known to be extremely OC friendly due to their low voltages.

As for power phases in motherboards, it shouldn't matter too much, but it should help a bit with more power phases, assuming they are designed well (i.e. digital power, etc).

I've returned a few CPUs at Microcenter and they never took it in the back to test it. They just took it and gave me a new one. Do they do that at the Microcenter by you or were you just assuming they do because Frys does it?

Try the following things if possible:

Adjust your LLC/vdroop (try 'high')
Enable internal PLL overvoltage if this setting exists
Set your RAM to run at default XMP/stock speeds if you've OC'd it
Set your CPU current to 140% and extreme duty power phase in the DIGI+ power settings
