X79 Overclocking Guide

wolvers · 19 Mar 2013 at 21:42

Just to reduce temps all round a bit more, I'm obsessed with silent fan profiles!

Also, does this platform benefit more from higher ram speed or lower latency? The best I've been able to get so far from my Sammy greens is 2052mhz 8-10-10-24-1t and 2400mhz 11-12-12-31-2t. I haven't had chance to bench them yet but my instinct is saying that 2052mhz cl8 will be faster.

I think so too. 11-12-12 is slack at 2T. 2052 will put less stress on IMC too so better CPU overclock.

I was hoping you'd make that last comment as I was thinking the same.

It's still possible that I can improve on the 2400mhz timings but I might need to hassle you some more to achieve that!

Go TRAS 21, TRFC 96 and enable Rampage tweak mode 2 first.

Reboot and see how this goes.

Tweak mode 2 set all the seconds and thirds too tight and it wouldn't boot at any of my previously working settings.

What's best for benching RAM OCing? SuperPi?

PSC IC man!!!

Huh??

Managed a stable 2400mhz 10-12-12-24-1T-96, pretty pleased with that. Not bad for 4x4gb.

Also broke my 10/2pt goals in Cinebench.

Nice score wolvers.

So after a while of using my 3930k at 4.5 and bench at 4.6. I've come to the conclusion my CPU is rubbish. It requires 1.415v to handle 4.6GHz....
I would lower my PLL voltage to see if I can bring down the vcore, but the Sabertooth X79 doesn't allow lower than 1.8

one of the biggest letdowns of this board I think.

With that in mind is there anything else I could try?

Have you tried PLL on auto Rossi? The min value I can set on the xpower II is 1.82v, though if I leave it at auto it defaults down to ~1.7v.

Yaayuh! · 30 Mar 2013 at 14:23

On auto it sits at 1.8-1.81

Intel spec is 1.8v for SB-E on PLL. Most like 1.65 though which is not a setting on many boards sadly. They offer loads of over volting options but no under volting.

Informative guide, looking forward to playing.
8 Pack, I am putting together a new system. Are there any Quad channel 32GB memory sets you would recommend over the others?

Thanks

With 32gb the issue is compatibility not speed. Not many CPU will get over 2133mhz 32gb stable.

I personally to ensure comp would go with a set of DIMMS on the QVL list for the board.

In X79 terms ASUS tend to be the most compatible boards either the P9X79 range or the ROG boards are great.

Now if only i had X79 to try this on
Going to keep my eyes out for some bargains and transfer over

Go X79 mate you wont regret it.

Will be my next upgrade. Should be on x79 by the end of the year. Can't warrant investing in a 3770k when this is not far of the same price.

How would you rate the 'Gigabyte X79-UP4 Intel X79'. I'll be looking to go with 16gb of Kingston Hyper X @ 2400 as it's dead cheap compared to other manufacturers. Would this be a good move or would the Patriot/Samsung be a better investment?

8 Pack · 11 Apr 2013 at 11:10

I had problems with compatibility of that board with the Kingston Beast RAM. I am not sure I can recommend 2400mhz RAM with that board. All the RAM manufacturers you mention make great sticks but my issue is totally MB comp.

Thanks for the response.

I purchased some Patriot Intel Extreme Masters 32GB (4x8GB) DDR3 PC3-14900C10 1866MHz Quad Channel Kit in the end. There are some Patriot on the QVL, but not a 32GB set.

I also purchased the Asus Rampage 4 extreme and followed your guide. I have only been tweaking a few hours. So far I have had booted into Win7 and ran 3dmark2011 at 4.7GHz on the cpu at various memory speeds (all at 100 strap) I did manage a benchmark at 2133, but with timings as loose as a clowns sleeve. I am at 4.5GHz (100x45) at the moment with the memory on 9.9.9.24 CR1 - 1866. Not sure what to try next!!

8 Pack · 11 Apr 2013 at 22:04

you could try 125 strap and 2000mhz RAM speed with similar timings.
