300% of memtest just serve as a milestone. I dun have SP1 installed on my bench hdd.

As you know, memory are behave different even the same pair and the voltage vary from motherboard to motherboard. One work higher and one work lower.

Definately my pair is not binned from GSKILL.

PS: Received quite a few of PM enquiry about GSKILL memory hence offer GSKILL memory Mass Order. Limited Time till 31/5/2011 depend on response. If respose good, order will proceed early. Pls PM me your order. Payment will be through PAYPAL.

Hi Guru,

Care to share the setting for 5.2 Ghz voltage.

And i need to know the system agent / pll / cpu IO as well.Thanks for sharing.

PS : 2 cores / 4 cores with or without HT please do let me know ya.

i overclock with the bios setup and i timex the multiplier to 37 but then cpu-z shows only 3.3++mhz. Issit correct? and the temperaure is around 30-40+ wont overheat rite?

2236MHz 8-11-8-27 1T @ 1.8v
Is this OC record good on Z68?

well i've seen 2352MHz being the highest on P67 so far and believe Z68 also should be able to do the same.

Cool~ May I know the rig spec of this record?

Specs can refer to his ss.
Afaik this guy has his 2600K clocked to 110 Bclk and that's the highest ive ever seen so far.

Hi owikh84,

Care to share the setting for 5.1 Ghz voltage.

And i need to know the system agent / pll / cpu IO as well.Thanks for sharing.

PS : 2 cores / 4 cores with or without HT please do let me know ya.

simplified settings for 5.1GHz (IIRC)
- Load extreme profile
- Int. PLL overvolting = Enabled
- VRM Frequency = 550
- LLC = 100%
- RAM timings 7-10-7-27-1T
- vCore = 1.51v
- vdimm = 1.65v
- VTT/VCCIO = 1.05v
- vPCH = 1.05v
- VCCSA = 1.05v
- CPU PLL = 1.8v
- multi = 51X
- 4C/8T HT = Enabled
- EIST, C1E, C3/C6 = Disabled

that's all i could recall with my old chip on MIVE. Hope this helps.

2600k
p67a ud4 b3

having a difficult time getting it stable at 4.8

right now it need 1.51v at bios llc enable on load vdroop to 1.485

crash over and over and over

vtt at 1.25

multi 48
pll overvolt enable
ht enable
all powersaving off

You need a better chip. Trying hard on a dud chip won't get us anywhere

i have try to run folding for 5 mins n its good with 4.8Ghz , 1st n 2nd try it get BSOD coz of not enough vcore . 5 mins stress is enough to try out or need longer time ?

i'll be damn

doing fine on a single rad tho

81'c max on 2 core with a LT and a GTX 120 with a GT on pull

That's not bad but my Hyper 212+ with 2 x F12 push/pull is no where near 80C when I was doing 4.8Ghz with my previous i5 chip

did u prime those claw??

my 2500k might be hotter, hyper212+ with f12 push/pull... easily exceed 80c on 4.5ghz with LinX AVX @ win7 sp1.

Try this new BIOS:
GA-P67A-UD4-B3 - F5b

Obviously I do but I'm in an Aircond room though. It took me 1.45-1.46Vcore at that time.

I don't have the latest AVX back then. My current chip is better, 4.9Ghz at 1.43-1.44V but I have since used back my WC and in the 60's during Prime

im already on those

saw ur post at tweaktown forum and grab it but still no avail

a mere 4.4ghz need 1.4v at bios and the vdrop and vdroop is bad

gonna add another 120 rad to this loop and gonna see how much of an improvement i can get

You can switch BIOS to Z68X-UD4-B3 with 10 levels of LLC. .........modded by me and have Touch BIOS.



I am also on Z68X BIOS and need less Vcore then for P67A(B2/B3).
