So you WERE Able to get another 500 mhz on the CPU after enabling internal PLL overvoltage?
Or you were able to get 4900 mhz WITHOUT enabling it, but just putting the vcore at 1.5v?
Yes, you would 'think' that Auto would enable it but I think "auto" only enables internal PLL *IF* you go past a certain mhz, and then the board decides to turn it on as a preset. What I should have said is that it probably doesn't "check" the CPU itself to see if it can post or not, and enable or disable depending on that.
Yes and yes, I got 500mhz more after enabling internal pll because I too think auto must enable after a preset point but this poor example can't reach that point so for this CPU it must be set manually.
Off to the shops I go .......

:) got new 2700K today just first attempt here batch # 3143B250 S/n:A1605
this is with air cooling with noctua d14
http://imageshack.us/f/13/2700ktest.jpg/
booting 4,5Ghz under 1.2v to :D but now stable at all, just awesome cpu.. better than all of mine 2600K´s before selling
Merry Xmas to all ppl :D:up:
Jeez you guys are making me want to play with my 2500k..must..resist..urges!!
It seems that 2700k might have worse overall max multi but better 24/7 clock capability, Eva was saying his does 51x with internal PLL disabled (although his does 5.6ghz too)
Now .... Which to buy next .....
:D
The 2700s should be binned slightly better though the high end remains to be seen like aussie stated. The way the new 2600 batches are I think I would try a 2700 but either one will stomp some serious numbers with good hardware.
I bought a 2600K and a 2700K today, proceeding with testing now ....
:)
Edit:
Ok first cpu is a 2600K Malay L142B435 - stable at 5400 1.500v but wont hold 55x at any volts, all other settings are default, what else can help it get further? Or best just sell it as a 54x cpu and try another one?
Next cpu is a 2700K ..... 3122C589 .... but I will try that another day, for now I will fiddle with this 2600K some more. I wish my 3105C Costa Rica didnt just die ....

Hello
First test H2O 2600K Retail
http://tof.canardpc.com/view/dd500ab...a21a4b572c.jpg
Guys, I have a 2700K here that I am testing under single stage, I got it running light benchmarks (1mb Pi and 32m wprime) at 5400 with only 1.400v but it ramps up hard after that and wont run at 56x even with 1.6v, is there anything I can do to get more out of this cpu or is it hard-walling even though it clocks well up to near its wall?
:P
Edit: This cpu seems stable at 5ghz with 1.330v ... pretty amazing if you ask me, the SS must be helping this.
:)
Man.... this is not making me feel any better about the 3135B460 batch 2600k that I picked up at MC this week. Gonna play with it this weekend. Here is to hoping it can hit 5Ghz with 1.45v or less.
Only one way to find out.Good luck to ya.
What is the highest safe voltage allowed for 24/7 usage?
Thanks.
So far, with the BNIB M4E-Z from MC I was able to reach 5Ghz but on 1.43v. I will try to trim it down a bit before I start benching the open-box M4E-Z I got from NewEgg.
Stock settings [loading optimized defaults from BIOS] I was able to hit 107 Bclk on the above mentioned board... Is that any good?
PS: Batch# 3135B460
Well, the CPU is under a Corsair H70 for now; but it is not doing that much since the room where the PC is located is pretty small and has a very powerful steam radiator a few feet away [close valve don't work; been meaning to get a plumber in to cut it off] I'll try for max multi once I order/receive the water block for the motherboard.
I want to make sure I keep this board before I order the parts for the loop.

Swapped in the NewEgg board and so far I've been able to lower the voltage to 1.42. This time around I did a fresh install of Windows 7 Pro x64 [used x86 before], and I ran Lynx with 3GB+ instead of the 1GB+ I had available with x86 and it is going through the 20 passes like a champ. Looks like this is the one I'll be keeping, since I also might have done a better mount job on the H70 because the highest temp so far is around 6 degrees lower than before.
Results so far:

You should update your realtemp to 3.67.
Why isn't you W7 patched to SP1 for the AVX extentions boost? If it is patched, then you can update LinX manually by getting the Linpack binaries from the Intel website and putting them into the proper linpack folder to overwrite the older exe files (not sure if they need to be renamed or not).
My bad... I took the OLD 4.5Ghz club files from my downloads. The new ones are jacking the GFlops over 113.
Guys, I have struck a weird one:
I have a borrowed cpu here, from a forum member over here, he got it up to 5700 or so 2C/2T for pi on air cooling, so now Im testing it on single stage but something isnt right. In normal testing I got it passing running 32m pi at 5000mhz down to 1.320v but it locks up at 5100. The only way I got it to run at 5100 is to disable internal PLL override, with it disabled I got it up to 5600 but while its disabled I cant get it to pass 3D at any clocks. What the hell is going on?
:up:
Does default VID of 2500K/2600K relate to VCore need @ 5.0GHz?
Every CPU is different, but, to be direct, a CPU with a lower default VID tends to require less voltage for 5 ghz, but runs hotter as a result. The "leaky chip" phenomeon was shown back in the X58 and Core 2 days. A higher VID chip runs cooler on average but usually needs more vcore. It goes without saying that the low vid hot chips are the ones that benefit best from extreme cooling.
Exactly right, plus I would like to add that the high vid chips seem to clock higher in my experience on water or better.

Hey why are you running CL8 when your ram is CL7 on XMP?
BTW it's Sandy Bridge not Sandy Bell in your signature.
Is Sandy Bell (like in animated story)... :)
Yes Cas 7 mem keeped at cas 8, at 1,52 Vdram, for perfect stability of cas 7, need more than 1,63 Vdram, no needed...
Cas 7 or cas 8, is inobservable for 24/7 using, or gaming.
OK, so I was bored yesterday and decided to try the above. I figured I would post this just for more info on this batch #...

I tried 57x and could not boot into Windows, doesn't get past post. Is it worth upping the vcore to like 1.58 to see if 57x flies?
Not really going to use this CPU that high as I don't have the proper cooling, but was curious as to my max multi.
Thanks! I'll try 56x102 this weekend. Like I said, I don't have proper cooling to run it at full 4C/8T at those speeds, but that maybe someone else might want to take it off my hands :)
Guys, what the heck does this mean?

I set multi to 57x with reduced BCLK and snapped a screenshot while finishing a 1MB prime run and cpuz is showing 59x .....
Edit: I kept playing with it and got it to 59x set in Windows ... wtf ... it wouldnt do this with single stage on my M4E but loves my P8Z68-V pro gaming mobo on water ..... its possible I guess ...

Weird.
I bought a 2600K L145B654, VID is skipping .98 - 1.3xxx depending on CPU usage. Can do 52x, but heat is my enemy now. Even an H70 can't keep it down!
Looks like a decent chip aussie :up: If you want to check for max multi dont "trick" the CPU by using less then 100 bclk. Try and find out what multi it maxes out with @ 100 bclk and work up from there adjusting the bclk.
Been a while since I posted here but got a 2500k and without any effort at all, ie going outside into a cold shed and rebooting and jumpering constantly into the wee hours, I have managed to get it aircooled up to 5.1Ghz with 1.34v in under 2 hours.
Are all these chips like this? What is the normal frequency cap for this chip on air with less than 1.5v?
Andy
Most of the 2500/2600K chips can run much higher then spec though not as many numbers like the older batches. I just tested two 2700K in the past week and they are pretty decent. One will do 55 multi at 1.50v and the other is just 52 but at 1.42v. Both chips where tested in my torture rack with remote water loops and killa hardware which makes it pretty easy. Both chips also run cool for mid number vid compared to some of my 2600Ks.
Hey, yeah I know it's "tricking" it but I have tried lowering bclk to get a higher multi (as I see many here do) but all previous attempts at this have been lucky to get one multi higher so surely this is odd. This chip gets 57x under single stage and can bclk up with 56x multi up to its max validation of 5812. I can't get it to boot at 55x with 1.55v on water but you can up the multi to 59 as shown. It's for sale anyway so I can grab another that clocks better on water.
Ivy is getting closer so I don't even know if I should be buying any more sandy chips
:D
aussie-revhead your chip is good can do X59 multi
I just picked up an i5 2500k. Do all these have the same s-spec of sr008?
The batch number showing on it is # 3151B188
Also got a P8P67 PRO
It will be watercooled. I will get it fired up in the next couple days and see what it will do:D
@ aussie
great job is that my old chip?
x59 is awesome however it is weird that it wii not boot that under cold with bclk set to 100.
Yeah it's your chip and yes it's odd indeed, I think my single stage isn't cold enough so someone with better cooling may have better luck. The more I mess with this M4E the more I'm beginning to think it had issues but I'm not about to buy another one to find out, I will wait and see what happens with Ivy,z77 and Kepler.
Thanks.

Playing with 2700K and Noctua NH-D14, this is my introduction to Maximus IV Extreme-Z and brand new chip available in Croatia... 3152B027
First boot in windows 5.0GHz with 1.31V 4C/8T

Boot in windows 4C/8T up to 5.6GHz

After that turned off HT, two cores and boot in windows 5.8GHz 1.64V

59x past bios post but freeze at win 7 loading screen so I'm sure it is 59x chip but can't boot in windows 5.9GHz on air so I will try with bclk to get me few mhz more for amazing cpu-z validation on air... I'm in love with this chip...
Guys, which voltages other than vcore do you tune to improve stability? I generally only change vcore and that's been done but the last few pre-tested CPUs have not lived up to expectations so I know I'm doing something wrong. For example, I have a 2700K now that the previous owner got to 5200 1.42 LinX stable but my LinX fails as soon as load kicks in at 5000 1.42v. This CPU also seems to cause vdroop where others haven't, eg with second highest LLC I usually find loaded voltage at windows doesn't fluctuate and sits at set value where this CPU droops 0.01-0.02 under load. It's not excessive but it's not common in my own testing.
Any help would be great
:)
For 24/7 I only tune vcore, vccio, and pll. Maybe you should play a little with the vrm response also. I always try to set as max vdroop control as possible, I preffer that voltage go up and not down in load scenarios.
Indeed my friend, and that was oc'ing straight out of the box, now with some time spent familiarizing with the motherboard and open window in my room this chip is really badass

Its easier to do that with a 2500K than 2600K ...

Whoopi fooking do nob-head.
I thought this was a thread to post experiences and not some sort of pissing competition.
Things have obviously changed sinced I first started posting here. To be honest it is all rather easy nowadays, you no longer have to know how to solder bits onto motherboards, graphics cards etc and simply just have to spend money it seems.
This sort of attitude is part of the reason why I stopped being interested in participating.
I shall feck off again from whence I came.

Andy - sorry mate it wasnt meant to be a dig, what I meant was im frustrated at my own attempts to achieve this with 2600K and 2700K, and I see so many people posting results like this here and I cant, thats all, it wasnt a dig.
Im on my 12th cpu, not alot by some standards but to me it is alot and still no luck. All I meant is that its a little easier without Ht, thats all, I didnt mean to rock the boat.

Just got a i7 2600k Batch L145B070. Malaysia I'm waiting on motherboard.
Anyone know anything bout this batch? I can't seem to find anything on it. Most people seem to have Costa Rica
Greetings XS,
Long time member but been out of the game for a little while, picked up a 2500K because I needed an upgrade for BF3 multiplayer, threw it on a cheapo ASRock motherboard (the 120$ one) and threw it in the watercooling loop on my old Swiftech Apogee, shares the loop with Radeon 7970
So far I am priming at 4.8Ghz and 1.288v but my temps are about 70C under load! Either these new chips run hotter than I thought they would, or I need to re-seat my water block. Even for a Swiftech apogee I think I should be getting better temps at such low Vcore. But I won't complain because 4.8 Ghz at 1.288v looks to be pretty decent from what I've seen.
Updates and max multiplier testing to come later on when I have time.
Cheers
edit
chip is malaysia, L201B309
4.8 ghz 1.3v to be prime stable past 30 minutes
5 ghz 1.4v prime stable
4.7 ghz takes only 1.25v
bootup at 5.4 with 1.44v
Chip runs hot. Have reseated water block twice. At 1.3v still exceeds 60c under load. IHS contact inspected, appears IHS is... uneven?! Anyone else lap their sandy bridge IHS yet, results??
L147B458
2600k
5550!!!!
Yet another unlucky bastard here. 2600K L147B654 1.525v @ 5.1Ghz, max. It's cooled by H100.
Totally crazy. Some are hotter than others, I am thinking.
My IHS looked like one corner was slightly lower -- this might be a symptom of the chip not quite being evenly seated in the socket somehow. But I when I reseated the water block, I was sure to tighten down one corner first to get contact with it. Still though my temps haven't really changed.
I am conjecturing that the chips running x volts and y frequency should only vary in Temp significantly because of varying levels of contact between the IHS and the core. I have been out of overclocking for some years but in the AMD X2/Opteron days we were taking razors to the IHS's and chopping them off. IIRC though Intel solders the IHS down to the core so IHS removal has been pretty INCONVENIENT for some years now.
It would be too bad then, if some poor contact fusing the core to the IHS was causing our terrible temperatures.
Tying 2550k's now. No threads so Ill pot it here.

x56 max so far, logged into Windows but got a BSOD before I could get a screenshot. That was at 1.615v on a Corsair H60 with the computer outside (outside temp 15*C). I was too wussy to try any higher vCore but I'm pretty sure if I got into Windows and then BSOD'd that would make this a x56 chip correct? I did manage to get this though which was better than my x54 max I got back in July last year with the same chip!

2550k Batch #L115C216
Finally got some better cooling, bought a Single Stage unit built by runmc. This chip runs very hot, and needs a ton of vcore. My 24/7 install of w7, and the wrong version of wprime.
My first try on a the new unit, I feel like a kid again :D
Thanks!
Next I need to get up the nerve to try it on the R4E and 3930k.
Some of you folks are unhappy unable to hit 5.0Ghz with 1.4v, mine requires 1.390v for 4.5Ghz and 1.452v for 4.8Ghz... which is really pathetic!
I've never really played around the PLL voltage its always been in auto, how would I know if I need to decrease or increase it ?
I run my CPU PLL at 1.5500v,with complete stability,there are those that say running it lower than the default 1.8v can reduce the amount of vcore needed,and it helps reduce temps slightly. You could try starting at 1.8v,and work your way down until you cant boot,then it's just a case of fine tuning.
When you find the lowest PLL voltage that will boot,it's a matter of running some stress tests to fine tune,ie,you might be able to boot @ 1.500v,but being stable is not gauranteed,so you will need to fine tune until you are.:)
2500K | #3204B387
purchased yesterday at Microcenter to practice OC on the M5G and getting to know the board.
Specs:
- I5 2500K
- Maximus V Gene
- 2x4GB Samsung 30nm kit
- Corsair H100
- Antec Signature 850W
So far the CPU was doing great.
After few fine-tuning I reached 5.4GHz on water, and this speed *IS* as stable as a rock.
I mean really. temps under heavy load were around 75-79c, and it passed all the 3Dmarks with 560Ti clocked to 1GHz/2500.
in the pics the CPU V is 1.6, but I was able to get about the same results with 1.53V.
http://i.imgur.com/abg8L.jpg
http://i.imgur.com/vBobX.jpg
Now after I reached this stable speed the CPU seems to hit a wall.
I tried everything that I know - blasted voltage, minimized voltage, underclocked, tried a lot of mem timings, lowered mem to the lowest and to the default, and still - the system can not go over 5.4 not in BCLK or in multipliers.
What am I doing wrong..
what am I missing.
I see a lot of people doing X55 and X56 on the BCLK and benching with no problem.
:mad::(:(
Looks like that is the limit for your chip.
Welcome to SB hell: it's the CPU... hello IB :)
Yup that's it...most duds happen to be the i5-25XX's.
2600k's are usually better but that batch from that MicroCenter $199 sale was pretty P.O.S. silicon.
2700k's are highly binned enuf not to be a dud but mediocre to great.
For regular moderate overclocking for 24/7 IB is the way to go - 4.5-4.6ghz easy overclock on air, up to 4.7-4.8ghz before you start cooking eggs and bacon.
You can set it at 1.6v and try testing for stability.
Then later you can try 1.55 - it may or may not be too low for your system - for one of mine I could pass Prime with 1.6 but not 1.55v.
this is my beloved x56 some screens i took ago i will retest as its a chip that can do very nice on water on low volts this screens are on 3 fan rad, now i have a 4 fan rad i will retest all soon
