5GHz Overclock advice

Default LLC is silly.

Is that of stable?

You really want the LLC to make idle and load voltages equal.. So it'll read 1.4v (let's say) at idle and 1.4ish under load too. That'll be a good OC.

You need to raise the LLC to high/level 3/4.
 
Well you can have it upping your voltage by using a lower vcore and a high LLC.

So it'll idle at 1.3 then on load itll rise to 1.35 (or something). Though i found that less stable than the other way around.
 
When it BSOD's are you taking note of the error. It may be you need more VTT not vcore. Next time take note and find a bsod code list.

IIRC 0x124 is more VVT

Just because.
So long as temps stay below 60 odd I'd be happy. + it'd be nice just to see if I could too

I'm also having another push for 5GHz on my 2500K. I made some progress at lunchtime, setting manual voltage to 1.465 with LLC settings @ extreme, it peaks at 1.502v & 63 degrees after 5 mins of Prime95 (i'ts all I had time to do!). I tried turning down the LLC after this but couldn't get it to boot into windows.

Do we think 1.502v peak might be ok to run for 6-12 months? Bearing in mind if I do kill it I will just buy a Haswell! (Though ideally I would like this one to last until the 20nm chips come out).

I tried at 1.450v but bluescreened with WHEA uncorrectable error a few seconds after starting prime. Haven't tried 1.455/1.460 yet - will do tonight for sure.
 
1.42Vcore at with LLC step 7 seems stable. Under load it's actually getting 1.488v but temps max out at 51*C with the fans turned up.
Still cant get below 7.5 seconds SuperPi 1m.

I wont be pushing the RAM any more, I only paid £20 for 8Gb last year so if I kill it I'll be ****ed about having to pay £70 to replace it!

Nice, I'm not way out from what you have got but as 1.45 wasn't stable for me I am wondering have you changed any other voltages manually? Like PLL, VVCIO etc? The only voltage I have manually set is Vcore, everything else is on auto.

Cheers,
 
I have all of the voltages set manually but at their defaults. only thing I have touched is the VCore @1.420v and Multi step load line (LLC) step 7. Oh and Ram 1.550v

What SuperPi times are you getting?

OK cool thanks for letting me know. I have never actually run SuperPi before! Shall download it tonight and let you know.

On another note I've had absolutely no luck in OC'ing my 2x4GB G.Skill 1600MHz, it's XMP is 9.9.9.24.2T. I have tried at the default mobo timings of 11.11.11.11.28 with clock set to 1866MHz and also 8.8.8.8.24.2T @ 1600MHz but no luck there either, both either dont post or I get to prime95 and the threads bum out. I have tried voltages of 1.55/1.60/1.65 but it doesn't seem to benefit at all. Any tips here would be good, I am kind of guessing with the timings so this is no doubt why I'm having no luck, that or this memory just wont run above it's rated spec.

I've no idea with the Ram tbh. Somebody on here suggested those timings to me and I've always ran them with 1'55v for some reason. Probably just lucky that they happen to be stable!

Yeah me neither, going to stick with the XMP timings for now, which are good anyway really.

SuperPI 1.9 1M calculation @5.0GHz: 7.547s (never run before so nothing to compare to, is this score ok?)

I'm running at 1.460v now, gonna set prime going for a few hours to see if its stable here
