over clocking a sandy

Goshawk · 9 Jan 2011 at 09:29

just wondering how easy it is to over clock them to the kind of level over clockers are offering with bundles and systems? i want a sandy and built a system but then OCUK rather annoyingly put out some fairly decent looking rigs with a 4.6 overclocks. and if it is easy should i stick with airflow or watercooled?

I hear its as easy as eating a bacon sandwhich.

4.6 should be fine on air.

oh no really? i hate bacon sarnies

sounds good maybe i should go water and aim for 6.4

6.4 would require something a little more exotic than water

Yh like liquid nitrogen and a belief in an overclocking god.

For most people getting a speed such as 4-4.2GHz is as simple as changing the multiplier in the bios.

infidel....don't question my faith!!
people are getting 5ghz on low end air coolers, is that not proof enough?

It would stand no chance of getting 6.4ghz with sandybridge not even with air cooler, not even with custom water

4.6ghz is easy

Enter UEFI/BIOS

Set multi to 46

Set Vcore to 1.30

SET CPUPLL to 1.80

Everything else on auto

Actually, these chips don't do well under LN2 or DICE setups as they prefer temps 15-20c, and when sub zero actually downclock.

These chips are not even the enthusiast chips!

Makes you think how good are the ones coming out later in the year!

AMD Bulldozer better be something special!

I kept my eyes open for AMD Bulldozer too, AMD are normally cheaper than expensive Intel

Why is your sig showing as 4.5Ghz (maybe you forget to updated it ?)

I've run up to 4.9ghz, but have settled on a 4.5ghz 24/7 clock as it's on 1.28vcore with speedstep and turbo enabled.

Most likely impossible. 6400MHz with the max multiplier of 57 would require 112.5MHz bclk and most don't even handle 105MHz properly.

Fair enough. That's pretty good 4.5Ghz with 1.28vcore. Are you using intel cpu graphic or use your own graphic card ?

What is the windows index score for cpu graphic only without the use of your graphic card ? Only just wondering

No, using my own 6870 as it's a P67 board, would have no idea about the on die GPU, which apparently is the worlds first 32nm GPU for a bit of pub trivia :cool:

Is that AMD Radeon HD XFX 6870 6800 series ?

Yes, that's the GPU i'm using. The GPU on the chip is redundant and powered down when in a P67 board. It will only become operational when in a H67 or Z68 board.

exactly what I was just thinking.
I would be interested to know if it would be theoretically possible for a motherboard manufacturer to essentially spoof the CPU with an on-motherboard clockgen for the SATA and PCIe slots, as, as far as I understand, these are the bits that are sensitive to changing the BCLK frequency. Bound to be some shared pins stopping this in all likelyhood, but it would be cool.
Even assuming that it is technically possible, I still don't think Intel would allow any MoBo to ship with this feature, as it would directly contradict their decision to lock it down in the first place, and I could see it alienating intel from that manufacturer.
