i5-2500K/2600K batch number and o/c results

[aussie-revhead]

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?

[newhit]

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.

Raising system agent voltage will help some when maxing out the chip and meory, I hadnt tried it but Dumo suggested it and it did help on P67. On this Z68 though it runs at default just fine.

I understand.....................You were not talking below 0 degrees.

I am about to try my new chips...........on water and SS. Here's hoping I can get better results

[aussie-revhead]

Has anyone found that any paricular motherboard , or Z68 chipset helps these clock? Or is it all in the cpu?

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

cheers

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

viper u have the fastest chip on earth

[aussie-revhead]

Has anyone tried an Asus Maximus IV Gene-Z yet? How is drop/droop on these?

[Viss]

Strong little board, loadline works great

[The Viper]

viper u have the fastest chip on earth

HAHA


CPU@4.8, just a quick LinX run (no AVX), PLL disabled

Cold bug 2600K won't boot up @ colder than 0C no matter what.

Any sb chip that can go at least 5999Mhz on good air cooling deserve to be tested with subzero

57X is impossible to attain even with high end air cooling and gem cpu

lol what droop
i set llc @ 75% and no droop what so ever and vcore doesnt even go up rock solid while running linx
i boot @ 1.42 loads @ 1.42

wait, what???

[icecpu]

Why my i7 2600K OC 4.4GHz in LinX and Intelburntest Gflops output so low compare to others ?
Memory speed is 1600MHz (8-8-8-24)

you need to be running windows 7 SP1 to take advantage of the AVX instruction set, make sure you have the LinX version with AVX

[icecpu]

I don't have SP1 install, but I feel kind a low for that 4.4GHz OC
EDIT: Installed SP1, everything seems fine

[MaxxxRacer]

For comparisons sake, is 4.5Ghz @ 1.312 volts on air fairly decent? I'll post some screenshots later tonight.

@icecpu
Linx gives a lower score when HT is enable and yet You have no AVX Linx

Mine does 5650 Pi only on water but I cant get it to pass above 5250 3D, would cold help this?

wich 3D ? mine passes 5400HT on 1,62 water for 3DM11 and 1,59 for vantage, how come u cant pass 3D with such chip, 3D eat lots of volts at least on my tests...
my other x55 only SPI but passes 1,644 same 3DM11

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 B2

sometimes do that but she goes into windows



pd: im very sorry for what happened there mate

[aussie-revhead]

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.

post your settings you are using to bench 3D plz so i can help you further

cheers !

[aussie-revhead]

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.
