Hi all, i recently bought this http://www.overclockers.co.uk/showproduct.php?prodid=BU-063-OE bundle and have additionally installed a Noctua NH-D14 using the Arctic silver 5 and their line application method .

Im getting average idle temps of :-

Core 0 36
Core 1 31
Core 2 28
Core 3 29

And loaded with p95 Large fft's (max temps)

Core 0 57
Core 1 64
Core 2 60
Core 3 57

Im running 4500ghz @ 1.360v (4600 wasnt stable for me and i would rather loose 100mhz than up the voltage) and its now 24hour p95 Blend stable.

These temps seem ok to you guys, this is my 3rd heatsink reseat and core 1 is always higher than the rest ?

Also The core voltage seems to fluctuate anywhere between 1.360v - 1.371v is this normal ?

My power supply is a Corsair HX620 modular i have 2 1TB spinpoints and a XFX 2gb 6950 and a generic dvd RW.

Thanks guys

Thats some high vcore for 4.5. What are the rest of your settings.
Click to expand...

ok a quick rundown

BCLK 100
Turbo ratio all cores 45
Mem 1600mhz
EPU disabled
CPU Manual volt 1.350 (oc profile was set to 1.360 @46 ratio and the only thing i have changed)
Dram 1.52500v
VCCIO auto
PLL 1.9000v
everything else on Auto
Spectrum disabled

In CPU setup

CPU ratio 33
Intel Adapt thrm mang enable
Limit CPUID Max Disabled
Execute disable Bit Enable
Intel virtu tech Disabled
EIST Enabled
Turbo mode Enable
C1E Auto
C3 Auto
C6 Auto
 
I should probably also note that its an ASUS P8Z68-V board .. speed step doesnt function unless CE1 and C3 C6 are set to enable but untill im 100% happy i wanted to stay with the OCUK profile settings other than the slight drop in volts and ratio to 4600ghz
 
Our chips could be similar, mine's not fully stable at 4.5 under 1.34. I really don't want to put more volts into it long term so i'm staying at 4.5.

Cores 0 & 3 run coolest on mine, about 2 or 3 degrees below cores 1 & 2 when under load (and right now 1 & 2 are at 57 under load).

Did the bundle come set to manual vCore and speedstep disabled? :eek:

Right, i had a bit of a play last night and used the Offset voltage mode and set the LLC to Ultra down from extreme .. i havent touched the CPU power management yet so left all on auto, i enabled Speedstep properly and disabled the C3 and C6 reporting

And this is what i got ... seems stable so far and passed 100 runs of Linix.

What do you guys think ?

 
Hate to bump my own thread but could someone cast their eyes on the screenshot and put my mind at rest and maybe offer their expert advice :)
 
Mine seems to need at least 1.35 when running prime and it fluctuates between 1.34 and 1.35 as reported by cpuz.

However, that is with a MSI board which seem to overvolt under stress (vcore is set to 1.31 in the bios).

Certainly 1.36 at 4.5Ghz doesn't seem unreasonable, like me you don't have a lucky chip.
