i5 2500k overclocking proving to be a nightmare :( - Page 9

post #81 of 99

cann i just ask one thing which has been confusing me through this whole process. Why does it seem to work well when i increase the multipliers but the moment i increase the core clock ratio my system is unstable??

Munaim: The only way i seem to be able to get this system stable is with Vrise it's weird. I have worked out it takes about 1.356 v to keep me stable so 1.36 in bios right. Is my next challenge going to be adjusting the LLC to try get a constant 1.36??

LLC is there to help stabilize your chip under extreme, heavy, and regular load. Also helps with vdroop ans vrise. Is level 6 not working for you?

it's working in the sense that myoverclock works

at the mo this is how it's working for me

1.30v in bios
LLC: level 6

as a result in windows i am getting

1.332volts idle
1.356volts load

this appears to be stable so far

is this ok??


my other real confusion still comes from the fact that i get 4.5ghz just by increasing theturbo multiplier and leaving the core ratio at 33 i assume this is fine

The voltages are fine.

However, you need to "Enable Real-Time Changes in OS"

Then manually set your multiplier from x33 to x45.

Or you CAN use the Turbo-Multiplier but I would just go ahead and do that.

Edit - At that voltage, and clock, those are pretty nice voltages man.

so enable real time changes and then set core ratio to 45?

reduce the LLC to level 5 or 4 and increase the vcore, you may experience vdroop, but that is better than vrise. Also overclock using the turbo ratio. read the first few pages of this: http://www.overclock.net/intel-cpus/...king-help.html

I would do that but had a little go earlier and that would result in me having about 1.38-1.4 volts idle that cant be better than 1.332 idle and a jump to1.356 load surely??

I agree with you willsk, and that's how I have it. I'm using a higher LLC than you (8), but at a higher clock speed. I'm netting the same load voltage, the same voltage reading when in bios looking at the HW monitor, so I figure why not see a lower idle voltage if the other 2 are the same regardless where I set LLC (but with vcore adjustments - higher LLC = lower vcore setting).

I'm not sure if that last paragraph was clear. This is what I mean:

LLC 5 = bios HW monitor shows 1.488, cpuZ load shows 1.428, vcore set 1.430, idle shows 1.488 fluctuates over 1.500

LLC 6 = bios HW monitor shows 1.488, cpuZ load shows 1.428, vcore set 1.410, idle shows 1.464-1.488

LLC 7 = bios HW monitor shows 1.488, cpuZ load shows 1.428, vcore set 1.385, idle shows 1.428-1.440

LLC 8 = bios HW monitor shows 1.488, cpuZ load shows 1.428, vcore set 1.360, idle shows 1.404-1.416

CPUz and other HW monitors seem to read voltage in .012 steps (1.404 1.416 1.528 1.440 etc etc) that's why you're not seeing changes in Windows when you make small changes in bios. At some point you will make a .005 or .010 change and you will see a .012 drop in Windows. I don't know whether this is common to the chipset or just a Gigabyte issue.

For *my* motherboard, cpuZ 1.58.5 and EasyTunes6 show the same vcore readout at the same time.

Hey everybody...

How's 4.24 @ 1.08V looking for me?

Good, bad, indifferent?

Thanks!

level 5 seems to do the best job under load, however Idle votlage for some reaons is just stupidly high, I had that exact same problem with another member, wow gigabyte....... Just get yourself another mobo bud, that's just ridiculous or wait for an bios update to fix this 'issue'.

At the moment, I don't even think you can use Offset votlage aswell, because Gigabyte again have restricted user's by only allowing LLC controls while using manual votlage, again im not sure if that applies to your mobo but I do remember coming accross that before.

Sounds very good, but what are you using to read the vcore? try easytune because cpu-z reads the VTT votlage on some gigabyte Z68 mobo's.
