You can disable those options.Quote:

Dumo has done a LOT for this thread, and for overclocking in general for a lot longer than most any of us, and is a great asset to any forum he posts in. Judging by some of your previous posts, the same cannot be said for you.
Another 3103B306 with s/n. *A1281
SS @ -15C evap. idle temp.
It needs significantly more vcore than those 57Xs
Dunno about its IMC though, need more testing with more cold
So far....
http://img714.imageshack.us/img714/4...nshot065mz.jpg
Nice chip Dumo. IMC cant be too bad at all, it does 102+ bclk with ram up to speed, that is plenty high for benching.
That chip may be the gem you have been looking for when you get it colder. If not PM me, I know the perfect home for it.
Looks like some of these later chips are doing much better.
Hit aquamark with that setup asap :up:
Probably a background program is getting 90% of the attention of the CPU? Might want to check for that.Quote:

K series overclocking and voltage range recommendationsQuote:
Originally Posted by noobzed
Quick Note regarding Voltage Scaling – Internal binning of both D1 and D2 parts we discovered consistent voltage scaling patterns.
1. For K series parts, the stock voltage supplied will allow for consistent overclocking generally up to a multiplier of 43x. There is potential for the multi to be raised to 44x depending on the load induced. This default voltage range be approx 1.240 to 1.260 under load.
2. Increased range between 44 to 47x multipliers will generally require a voltage range between 1.30 to 1.375V with an LLC recommended setting of high to ultra high.
3. Increasing the range between 48 to 50x multiplier will generally require a voltage range between 1.40 to 1.500 with a LLC recommended setting of ultra high.
4. Increased range between 50 to 52 (52 generally considered peak max multiplier except for rare 54x parts) will generally require a CPU voltage range between 1.515 to 1.535V with LLC at Ultra High and potential fine adjustments to the CPU skew range.
The results below are based on the range of the CPU turbo multiplier when overclocking.
Results are representative of 100 D2 CPUs that were binned and tested for stability under load; these results will most likely represent retail CPUs.
1. Approximately 50% of CPUs can go up to 4.4~4.5 GHz
2. Approximately 40% of CPUs can go up to 4.6~4.7 GHz
3. Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)
Additionally it is recommended to keep 「C1E」and「EIST」option enabled for the best overclock scaling. This is different than previous Intel overclocking expectations where the best scaling was with disabled power states or power management options.
Update specific to D2 and retail parts: Jan 11 2001
As always ASUS strives to be at the forefront of performance and functionality offered by a quality bios. Keeping this in mind ASUS has been actively working in conjunction with Intel to optimize overclocking potential on ASUS P8P67 motherboards and K series CPUs. With the latest bios revisions ( 1000 series ) or 600 series for ROG specific optimizations have been made to the microcode and corresponding tables that relate to D2 and retail parts. These are improvement are in addition to general improvements in all respects. Present with this new build of the UEFI is a new option. This option / value is “ Intel PPL Overvoltage” this option furthers multiplier scaling considerably.* In addition due to the increase in scaling more exotic forms of cooling cannot be used and will be needed under certain multiplier ranges and corresponding voltages. The general maximum range for the highest performing dual fan air based heastinks still remains 50x to 52x.

andres and friends - my current 2600K can complete superPi 1mb at 56x with 1.63v but it needs near that to pass 3D at 5400 and 1.575v at 5200, is this common? Should I keep looking for a better one? Or just up the volts as needed for benching? How far can you go for benching on water before there is a big chance of killing the cpu?Quote:

Picked up a chip today, Batch# 3101A104. Max multi is 56x. Havent done any testing yet, need to get it colder to try 8 threads. Also need to update my CPUZ, vcore set in bios is 1.55v LLC2.
nice chip these Costa Rica batches seem to be clocking a bit better huh?Quote:

ocnub - fix up your vcore reading (later cpu-z) or at least tell us what you used ....
Any idea what they might clock to on P67? Would they do 2300?Quote:

Nice work Nub, I have the same card with a EK supreme block in one of my systems that really cranks also. That 06 CPU score is sweet, pushing 12K is respectable for Sandy.
Hi all
After some years on core2 e8400 i jump to sandy 2600k today and after some tests i get stable 4.2 ghz with 1.240v load cpu voltage and 1.22v on idle.Should i consider my cpu good ?Attachment 117459

I dont dare to go a lot in becouse of the cooling, it still hangs idle at like 50ish and in partial load 60-70. (25 ambiant)

guys, how much would a 58x-60x chip actually cost? I'd even pay 850 for one of those beauties :D

At 55x around 1.55v, for 56x 8 threads 1.62v.
3109C384
55X max multi into windows 7 (have screenshot)
56X got to windows options but froze at windows loading screen
57x was a NO GO for any windows options
Overall not a bad little chip. Its kinda funny, but apparently i can boot into my BIOS at any cpu speed including 6.4ghz, not sure how im able to do that?
EDIT: I should add these results were very quick and dirty, all on air cooling, 1.59V, i didnt mess with BCLK at all, all 2 core enabled
If it makes it to windows load screen at 56 but crashes it just needs cold.
Does bios screen say 6.4ghz ?
ok so 56X would be the max multi on this chip?
yeah I actually took a picture of it with my camera, its says 6.4ghz and all my other options stuck as well
Is there settings that need special attention to get the benefit of cold? I have had three 54x cpu's that all dropped in multiplier when I tried my SS.Quote:

From the EVGA Claassy thread somebody went to a 1500W PSU and beat the cold boot problem with a 970. Is that a good route to go (COST is :eek:)
(Got two "better" chips now tho....I hope:up:)
Its weird that your chip will boot to bios at 64x. Its hard to say if 56x is the max but Id say yes. Try dropping bclk to say 99 and see if it boots, or raise bclk tQuote:

The chip has a strong IMC, it passes 32m at 108.7 bclk. The other x56 chip i use runs best using the x56 multi, and runs the same max mhz with HT enabled, just needs a little more vcore to use HT, but passes WPrime and 3DM06 CPU test no problem.
They all act different, its best to try different multipliers and find the sweet spot for your chip IMO. Some will run higher mhz using a lower multi, some wont do high bclk and run best with the max bootable multi, Im guessing this is IMC related but its just a guess.
Another chip I had (but killed) was a x57 that I was able to boot at x58 when dropping bclk to 98-99. I was hoping to get it to run x58 for benching with dryice, but its been hot and humid, and I think condensation killed it doing my first dryice run.
Ask Dumo, he runs SS, but I think he had a chip that had a cold bug above +0c. Dont think there is a setting that will help with cold bug.Quote:

Did a little LN2 run with my 56 multi 2600K yesterday on a GB UD4, had to struggle to get the bclk up cause the UD4 only allows steps of 0.5 at a time.
The chip has a wall at 5650 MHz at 1,62 vcore but can bench everything at that speed.

It seems the flurry of results here has died down, are you guys still buying-and-trying to find a golden chip? Im tempted to grab another one and try again, but its such a lucky dip and its hard to sell used chips here.
:(
My chip does superPi at 5650/1.65v on water but wont pass 3D at anything over about 5250, would cold help this chip out?

I understand..........:)...........You were not talking below 0 degrees.Quote:

i had 2 costa rica batches...1 POST at x55 and booted to ONLY SPI in windows at 5500 with 1,644 straight from bios, the other 5600 but just POSTS imposible to enter windows as its beyond that on volts...for me such chips are useless, i still got my good all x54 wich i can be stable and bench at propper volts, so finding a x56 that can be benchable at around 1,62 will be awesome, still i didnt find one and i guess never as it understable that most ppl that find these batches are keepers

A little more info on my batch...3109C384 (My Frys has more of this batch, maybe I should bin a couple)
Highest multi with PLL disabled, booting into windows 7 64...51X
So apparently on my ASUS mobo OC settings arent initialized till after boot screen, which is awesome...you will always be able to boot to bios to change settings that fail, no more waiting till the board resets. FYI: I was able to boot to bios with a multi of 200x
Thanks OC Nub for that good info :)

Can you change BCLK by more than 0.5 without the board resetting it self? I've tested both UD4 and UD5 and they both locks up if I increase the BCLK by more than 0.5 before I save and reboot.
yes no problem here guess its a good UD7 B2Quote:

sergio - I dont know why, it wont pass any 3D bench above maybe 5300 absolute max and it needs like 1.65v for that yet it will Pi at 1mb 5650 1.63v .... it just reset on me running 3D11 extreme at 5276 .... ffs ... I might try a different mobo and see what happens.

Easy, everything is default other than ram speed and voltage, multi to set in os, multi itself and vcore.... LLC Ultra high (second highest - seems to cause no overvolting)
54x100 just failed with 1.65v in it .....
I have been trying to work out why my 3D11 gpu score had dropped by 3-400 points, I tried all different settings but I just got them back, I dropped my ram speed (2133 Mushkin) to 1600, so my physics and combined are down but gpu is up again .... it seems lke my mobo doesnt like my new rams ....
:(
From what it seems, all 2600K hit 4.8 under 1.4v, most under 1.35.Quote:
