HELP -- R3E + 17-960 above 4.2GHz OC

[SwiFt_wayno]

I have been at it for a while and i can't seem to get my rampage 3 extreme 17-960 stable above 4.2GHz.

Some help from you over-clocker's out there would be awesome :D, i would like to achieve a stable 4.5GHz / 4.8GHZ if at all possible

Specs:
Rampage 3 extreme
17-960 bloomfield (OC 4.2GHz)
24GB Corsair Vengeance
intel 520- 180GB SSD
2x Gigabyte GTX 560Ti S.O.C SLI
Antec 1000w true power Quattro

Full custom loop cooled CPU, XSPC raystorm block (GPU's are not watercooled as the cards are not reference)

all very squished into a HAF 922 😛

Temps:
CPU 0% - 29
CPU 100% - 60

GPU 0% - 35
GPU 100% - 72

IOH - 53
ICH - 50

OC specifics:

BIOS version - 1.0.0.1019

CPU ratio - 23
CPU turbo power limit - disabled

BLCK - 183
PCIE - 100
DRAM - auto
ULCK - auto

Do you have a block on the Northbridge as well? from what I hear, they run pretty hot.

That is about the average for the entire processor range. Not much more head room unless you go extreme with the cooling and even then it is no guarantee that you will get much more out of it. 1.4 was about where I stopped with some ambient over clocking, just keep an eye on the temps while under load.

You may find that your CPU and motherboard may prefer a different multi. I know with my first 920 I used a even numbered multi for best results 20 x 220 for a 4.4GHz OC on water. But the second one preferred 19 as a multi.

I dont have a waterblock for the motherboard unfortunately. I would love to find one tho, but that is in another post.
I have extreme custom watercooling, But 4.2 is all i seem to get out of it (stable) i can go right up to 4.8 before it crashes, that isnt stable

[HiVizMan]

Stable means different things to folks. No idea what it means for you.

If you can play your games at 4.4 and do the work you do on the system at 4.4 then the system is stable. If your thing is stress testing then that is how you determine stable.

[SwiFt_wayno]

yer it needs to be fully stable under an 8 hour stress test, the highest i have taken it is 4.8 max temps at 73 under 100% load for about 5mins then dies in the ass, if there is no more head room then thats fine it will be upgrade time in Feb 2014 anyway, it will be one build you dont want to miss out on. 😛

[HiVizMan]

All good so stress testing is your thing, huge respect to those guys who get into every little setting to try and eek out another degree out of their coolers and volt out of their system.

Good luck with the upgrade in Feb mate. You are going to have a good selection of products.

Cheers, I will be doing an extreme build with at least 2 of the most top end cards at the time, filling every spot I can in the 900D with radiators, and using rigid tubes for my LC loop.

I will do a build log on several forums it will be insanely expensive and awesome.

[HiVizMan]

Outstanding I hope you keep a build log and share it here with us.
