wow, really, most hit 4.8 under 1.35...hmmm, Im not sure where youve been looking?Quote:

^^Under subzero...yes, most newer batch will do 1.35~1.39 Vcore bios @ 5Ghz
a 2600K that can go 5.8GHz+ under subzero not necessarily can do 5Ghz stable on air/water with less than 1.395Vcore...and vice versa
Heres (4) 2600K samples from different batches/ Gigabyte UD7-B3 Single stage cooling @ -15C evap temp. idle...Lynx non avx
1st. cpu maxed @ 51X and 5140Mhz wall with 1.375Vcore bios LLC7 for 50x100BCLK

mmm will you be selling any good ones soon dumo? :)
How big is your phase change? I have sourced a 3/8 HP unit, will this be enough for a good 2600K?
How much volts are you using at max clocks?
:up:
Its an old Vapochill LS stock unmoded and it still can hold 2600K HT on oc'd.
For max. clock I use 1.585~1.644 Vcore load windows (max LLC) depend on the chip
I had vcore up to 1.7 last night trying to get my chip to pass 3D11 at 5400 , it seems like cold is the way to go.
PM question coming too.
:)
Yes. in general cold will help stability with less Vcore (it won't raise Mhz wall) as long as chip is free of cold bug
Heres chip with absolute wall @ 5230Mhz with zubzero/air/water.
Passed all benches 3Ds or 2Ds with 4C/8T near its max. Mhz wall
Some of higher Mhz. wall 2600K chip won't even do 4C/8T at 100Mhz. less than its maximum wall...

I didnt specify enough info. I am running a 2500k with air cooling (archon)Quote:

I wanted to run my 2600K on 4GHz (for 24/7) use.
Got it OC'ed now and set the Vcore to 1.250 v (CPU-z always seems stuck at the wrong voltage for me... ???).
Are these temps OK?

well done dumo.Quote:

more heat is generated & core temps are increased 10C+.
CPU-Z power draw is increased from 130w+ to 150w+.
I was 10 hour prime stable at 4.7Ghz v1.392-1.412 (depending on load conditions), but Linx w/AVX failed after 20 minutes. At that point I gave up on 4.7Ghz and went back to 4.5Ghz where LinX is stable at v1.312-1.332Quote:

Any reference about this ?
(Sorry by my bad English)
It's a very new batch. Be the first to add your results :)
my 24/7 settings
on a noctua NH-D14
Attachment 118747
Finally I need about 1,336v to get 4,5Ghz stable 12 hour prime (64 bits).Quote:

L045B386 close to yoursQuote:

Very nice clocks, yep and we are pretty similar on 24/7 settings! I was trying to find, but is there any write up specifically for the maximus iv board for the voltages, there are quite a few settings which I bet would work well to lower the vcore a bit on mine.Quote:

Your costa is a good one too Andre:up:
Imo, different in maximum multi on each of sb cpu (even from the same batch) have something to do with how quick throttling will start...
Take a look @ cpu #1 and cpu #3 above....running with the same mobo under single stage cooling and almost identical bios settings (vcore a bit different)...pay attention to cores temp on ea. chip. @ load...
cpu #3 can bench 4C/8T at -/+ 10 Mhz from its maximum Mhz. wall whereas the other 3 need significantly less Mhz to be able to bench Vantage, '06 or Wprime 4C/8T
I think Intel put a lock on internal throttling mechanism inside the cpu cores and ea. 2600K/2500K has different Mhz wall or core temperature limit which can trigger throttle...wonder if software mod. can open it up....like this http://www.asusrog.com/forums/showth...and-Workaround
Thanks Dumo but aint Costa Rica its Malay L045B836 for me the best chips, never tested a C batch from CRica but all others do the same they hit x55 at high high volts and they are stable at 5GHz on high volts, some are heaters some notQuote:

I'm just about to find out throttle stop proggy:)
Vcore scaling or more cooling will be a non factor at certain point
Theres must be some explanation of why (2) 2600Ks with the same batch and a few digits serial # difference have totally different Mhz. wall...and I think this trend will carry on to SB-E and Ivy bridge too:(
cool Dumo ill test alsoQuote:

i cant find Bidirectional PROCHOT on the MIVE...but opening Throttle stop its OFF by default...
Are all those runs on water? When I dint have water, with all settings on auto, I was increasing the multi and I went up till 5.2ghz (and I dint want to go higher), I'm yet to try anything higher then 5ghz, I guess I'll give it a shot tonight.Quote:
