I'm going for 4.8 to 5.0. I've got her on a Corsair H100 with Push Pull setup, so far everything seems good at 4.4 which is nice to see, it's a strange new world overclocking on the UEFI BIOS.

My setup is this.

3930K w/ Corsair H100
p9x79 Deluxe
16Gb Corsair Dominator DDR3 1600 8-8-8-24
Kingston Hyper X SATAIII SSD
Corsair AX850 PSU
6990 + 6970 TRIFIRE

I think that covers all the important things. I'll do all the other benchmarks later, right now I'm off to try BF3 with the new setup.

That's a shitload of volts for 4.4GHz! My old 990X did it with less vcore.

Yeah, I just plugged in 1.4v and 44x Multi and booted her up, that's the extent of the overclock...

I'm going to fine tune it a lot more, but it's a lot easier to find the right balance points with these BIOS's and CPU's.

These SB-E loves the Volts.

Looking better!

My new 4.7 wPrime score... wholly smokes the difference between 4.4 and 4.7 is OOGE!!!



Seems to be good and stable at 4.7 as well, I am hoping it's going to crack 5


I'm going to shove 5 in there now and see how she goes

I'll update anyway when it arrives

Cheers m8, I'll be shattered if I cant beat my 24/7 clocks of 4.6 on my 970.

[d-dave-b]

This seems to be the most stable / reliable OC I can push out of her.

I got into Windows at 4.9 but it's not stable at all, I've been slowly trying to creep up from 4.7 again with a lot more settings tuned, and I'm up to the 48x multiplier now... honestly, if it only reaches 4.8Ghz (or there abouts) then I'm going to be over the moon ecstatic... I mean I would have loved to get 5.0Ghz but I mean, 4.8 is still pretty darn close, and it's so damn smoking fast at these clocks it's not funny.

It's also not running that hot even though I'm shoving 1.5v in her. I think I have a pretty darn good processor

Hi d-dave-b, could you take a screenshot of the cpu temps at full load please.

I am seriously concidering grabbing a 3930k and a Asrock extreme 9 mobo(or Asus/Gigabyte equal.)

Thanks and appreciated Alan.

[Beetroot]

just got my asrock extreme 4-m + 3930k from auspc
Will start overclocking once i finish my phase change setup. Custom build that fits in my case

[snappy1]

I wouldn't be running 1.5v 24/7 on a 32nm cpu... you'll find out why the hard way

[walker_2003]

whats the go with http://www.cpubenchmark.net/high_end_cpus.html

3930k must clock damn well..

Yeah, I've brought it back now for 24/7. That was just a clock for seeing whether I could reach 5.0Ghz with her.

It's running at 4.5 Ghz at 1.375v 24/7 now and it gives great performance. I got about a 25 - 35 fps improvement in BF3, which is all I care about.

Before, I was getting 45 - 60 fps, now it doesn't dip below 60 fps at all anymore, it's incredible. BF3 at 2560x1440 with all settings at Ultra is just incredible.

I've got a screenshot here as an example of how it looks, all running at 60fps

[Ice009]

What CPU did you have before Dave?

[walker_2003]

I seen an article showing 5fps difference between 3.4ghz and 4.4ghz on Bf3 it's all gpu.. Try a 64 player caspian border round and report back. Some maps on bf3 sp run alot better then others too.
