September 26, 201311 yr yeah.while sorting out haswell chips,there was a direct correlation between cache(ring) clock and core,the better the core the better the cache frequcny,shitty core meant shitty cache freq.
September 26, 201311 yr My first 4770K comming next week.L310B487 wish me luck. L310B487 Tested Spi 32M around 1,28vcore :-) Coldbug -93 ish :-(
September 26, 201311 yr L310B487 TestedSpi 32M around 1,28vcore :-) Coldbug -93 ish :-( To bad, but how did it overclock on LN2?
September 26, 201311 yr L312B349 - 5000 1.38v on air. Coldbug -116.9. Validation - 6300 1c LN2. L312B364 - 5000 at 1.40v on air is not picked up. RMA. L316B319 - 5000 at 1.248v on air passes SP32M.
September 26, 201311 yr Got an L315B407 today, 5ghz is 1.38v. I guess I'll try on LN2 since it's my best 4770k so far.
September 26, 201311 yr L312B349 - 5000 1.38v on air. Coldbug -116.9. L316B319 - 5000 at 1.248v on air passes SP32M. Looks promising. Please will add your results after LN2 test
September 26, 201311 yr Crew 316 was terrrible for us sebro, we didnt find any 5ghz, you got a lovely cpu there lets hope it scales!
September 26, 201311 yr X6800/E6600/965/980X Rules works here again ? Hot chip on Air best chip on LN2 L310B488 5g 1.35 32m 85 degrees 6510 1.8 CB -134 CBB -132 very very hot chip wprime 4.3 1.25 95 degrees L310B488 5g 1.31 32m 67 degrees 6380 1.90CB -112 CBB -108 wprime 4.3 1.25 75 degrees

September 27, 201311 yr Haswell is such an interesting animal...so,after 15 chips.... -general rule for me,the better the core(lower voltage for 5 ghz) the better the cache/ring frequency -some chips can do 4.5 stable with 1.15 let's say but they end up not doing 5 ghz at all,while some require 1.2 and they do 5 ghz under 1.4 -VID could be an indicator of chip quality but not main factor,got 2 0.97 that would require 1.45+ for 5 ghz while my best chips*under 1.3 * had 1.02 -imc quality varies,but not related to core/cache,the best imc i encountered*3400 stable 32M with 1.15 vccio a/d had almost the worst cores i've seen requiring 1.3V just to enter os at 4.4 ghz -chips behave differenty when searching for lowest voltage for a given frequency,example while testing for 5 ghz 32M some chips would give not exact in round or sqrt,some would simply freeze the screen while others will do classic 101 or 124. -ram frequency play a role in vcore required for stability but not to all pieces,testing stability at DDR3-3000 some would require +0.02-0.3 over DDR3-2133,some would need the same vcore. Still have some things to figure out,maybe other members can chime in with experiences and binning multiple haswell so we can create a has$$well wikipedia here

How did you test stability? Which tests did you use(LinX, Prime95 or SuperPi 32m)? ))
September 27, 201311 yr At 5 ghz only 32M since i have yet to found a chip that does prime For lower frequency stability,say 4.5 i use prime with avx.

September 27, 201311 yr Hasfail much? ^ New one here, L316B316 around 1.475 for 32m at 5 GHz, can do 4800 uncore with 1.39 vring. Will try on singlestage.

September 28, 201311 yr For light benches like pi,pifast,2001 aquamark up to 1.5 is fine on air,i have not seen any degradation whatsoever
September 28, 201311 yr For light benches like pi,pifast,2001 aquamark up to 1.5 is fine on air,i have not seen any degradation whatsoever I didn't mean degradation I meant cpu themp. This cpu is hot at 1.35V ))) I can't imagine what temp will be at 1.5V ))
September 28, 201311 yr 4670KL313B428 5 GHz 32m 1,250 Volt on air. Will test today on LN2 I think this scales good under Ln2...Good Luck...
