Ok thanks.
Do EK Supreme HF usually have an odd contact on SB or do I need to lap the block? On all three of my 2600K's I get a narrow contact that seems to align with the core position anyway, are they made this way or should I lap?

I think not. I am running one on a UD5 with no issues, excellent block.
as above good contact and best block i have had :up:
Next time I lift the block I will take a pic but as it is consistant across three cpus I would expect its the block at fault more than the cpus.
:up:
Yesterday I put the my 2500K on ss...
I disapointed bacause my system doesn't boot on same clock like Air... only 55x100.0 was bootable ..with air I can bench all 2d at 55X100.3
All the air profiles that my system boots and run 2d benches were not bootable:(:( not even profiles X54 (or X56 with downclock)
The good is that the cpu benches all the 3d benches very easy.. but only at 55x100.0with more, system can't boot I didn't try 54X102(or 56X98.3)

How much difference in score is there between W7 and XP?
:up:
I didn't try W7 yet
Guys, how much difference is there in benchmark performance between 2500K and 2600K? Is the extra cost worth it for HT?

Sorry if its been asked before but what is a nice safe voltage for 24/7 use?
:)
I guess depending what you are doing with your pc,if you fold and use 100% all time i wouldnt use more than 1.3,if you play games and don't use your pc 24/7 you can try to 1.4V,of course with good temperatures.
Just benching and gaming, so <1.3 is plenty safe right? I might be able to nudge 4.8 at 1.3 or so.
:)
Got new batch L051B163 on my 2600K start playing with multiplier from X50,X51,X52,X53,X54,X55 are Go with ht of

testing now 4800mhz@Vcore 1.38v ht on seems good yet. runs up tp 5,5G with 1,52v to
5500 with 1.52 if you can bench 4c8t is very good :)
ohh yeah :) this is awesome

Or it could be very bad. I got one that wasn't even stable at 5Ghz with 1.55v not to mention 4.8Ghz at 1.50v!Quote:

With cold (around -10C) I think it will go 55X >104 BCLK at relatively safe 1.56Vcore depending on your ram, but focus on benching like 2Ds or 3Ds not stability torture tests (imo those tests relevant just for air/H2O cooling)Quote:

Vcore as praz said not real.
My 920 4.5ghz 100 linx 5.4gb run
bsod when i running on goggle chrome on 8 tabs doing some macro's running on all 8 tabs 6000 runs each on a certain job. :shocked::shocked:Fixed it later but wasnt a vcore but just as example
Real world application and daily runs are the real deal .
Been working on this one for a while, I got 4.8ghz down to 1.36v but 5ghz is still a mystery. I can get IBT and Lynx to go just fine but prime gives me a random restart every time.

Wow I thought those C chips were mostly sexy. Too much volts for 5ghz.
How much voltage is too much volts for air cooling? Right now I am able to get my 2600k(L042B243) with 1.5V for 5ghz and 1.525 for 5.2ghz.
I wouldn't be do 1.5 for 5ghz when you can do 4.7-9 for less then 1.4v.

If bumping vcore doesn't help with booting 56x then you may be able to get to 5.6 range via bclk.
Sweet spots for gem 2600K are 54X and 55X, it needs BCLK 107+ and 105+ respectively to compete with 980X @ >6Ghz. Then again rams should be able to run @ high BCLK
56X and 57X are those 2500/2600K that are 5.8+Giger
Got really tired of the problem resuming from S3 sleep with Internal PLL Overvoltage on for 4.9ghz with 1.36v set in bios, 1.4v load under linX.
Currently settling for 4.8ghz with PLL off so the S3 resume from sleep doesn't require a hard power off ond restart:
http://i246.photobucket.com/albums/g...8ghzPLLoff.jpg
Internal PLL Overvoltage: Off
Memory Frequency: DDR3-2133mhz
Load-Line Calibration: Extreme
VRM: Auto

CPU Current Capability: 110%

Vcore 1.32v set in bios, ranges 1.32v idle to 1.36v max under linX,
That is just a really nice OC... very nice. :clap:Quote:

I'm going to pickup some 2500k and 2600k at Microcenter , Any one here have experience with batch code number lately at MC ?
Which MC? At the Twin Cities/Saint Louis Park, MN, there are four batches currently available: L040B305, L042B208/243 and L050A853. Neither of these are great OCers, by the way. I have the L050A853 and it seems to be the better among them. But then again, it could just be my crappy board. Who knows since I don't have two boards to compare, I really don't know.:shrug:Quote:

Many of us here have gone through many chips before getting one that really cranks beyond multi 55 so yes we tend to want to keep them around.
According to Asus only 2 percent hits >5Ghz. Then what the hell is going on here? Lots of high clocks, and staying below max VID (1.52) is no problem at all.
Based on all warehouses availability this morning (according to drop shipment vendor Provantage)....14K of 2600Ks:)
Probly 700 pcs. will clock higher than average

I'm pretty sure I'm going to have to up the vcore a little to get it stable @ 4.2Ghz. What cha think guys?
I'm on air cooling for now.
http://theraptorpit.com/Upload/thumbs/2600k4iwi.png
Hard to say...what's the vcore reading at load? Your cpu is idle in that screenshot.
I know I can prime at a vcore reading of just less than 1.25v load at 4.5 ghz.
If you're completely locking up at 4.2 ghz and 1.20v before you can even run any programs, then that definitely isn't a good sign, since you usually need at least 0.05v higher if you freeze right after windows loads...
Can you prime at 4.1 ghz with a LOAD vcore of 1.17v? (no idea what you have to set it to in bios to do that at load).
today I bought two 2500K both with Batch # 3047A890
It is from Costa Rica as it is begins with the number "3", also it seems to be an early batch(2000 week 47).
theres a minimum vcore for sbQuote:

(the vid at 5 ghz is like 1.355 or 1.371, I forgot, but my last 5 ghz bench needed 1.404v load...)
I have a Biostar TP67XE and in the BIOS it shows cpu "request vcore" which is VID related... (if not in fact the actual chip's VID). Those three chip samples from the same batch all had different "request vcore" and the 1.21v sample was the best clocker out of the three.Quote:

Well since at default setting it showed a VID of 1.20 I manually set it to 1.20v in bios. Under load in CPUZ it dropps below that 1.20v, not sure if it was 1.189 or 1.198v.Quote:

Sorry this is all very new to me so I'm abit lost on some of the setting.
Is it normal for the muti to drop, say from x45 to say x40 when putting it under a load? Is there a setting I'm missing or something?
When I use the presets in bios like 4.4 it doesn't do the muti drop under load. But it gives it way more vcore than it really needs to do that clock speed.
At x46 I'm getting a lockup at boot with a post code of A3 witch is hand off to IDE X45 passes no trouble.
Test setup:
2600K
Asrock P67 Extreme6 (B3) Edit: bios version 1.60v came out yesterday using now, board came with 1.50v but was a really bad bios. 1.60v is some what better at OCing.
G.Skill 1600 7-8-7-20 1.35v 2x2GB
Doesn't look good to me for this chip or the motherboard. One or the other is the culpit.
