4930k RIVE 2133mhz RAM

There is some progress:

CR 1 results in system instability

5-124-7936-12-7-26-6-6-8 appears to work fine.

However dropping tWCL to 7 instantly reboots my system. I haven't tried changing this in the bios yet, I'm just running a test on the other values.

EDIT: tWCL 7 in bios is also stable...

It actually looks like I might be able to pull my primary's down as well

9-10-9-26-2 appears to be stable...

Going to try 8-10-9-26-2 from bios shortly. - Stable... Will post once PI has finished.

Dropped a few more of the timings:

Where should I go from here?

I can't get CR1 even at CL 10...

First set of PI causes Error in round

8x4GB does seem pretty tough to tune!!

I have managed to drop the DRAM Refresh to 7280

and it's still stable running PI, will trial this with light gaming through the evening.

(primaries are 8-9-9-23-2)
(Seconds 5-124-7280-12-7-26-6-6-7)

EDIT: had a couple of crashes, but they seem to be vcore related. So I upped it to 1.34 from 1.325 to see if it resolves.

No problem...

I'm pretty pleased where I'm at right now!

A little more work and I think I'm there.

Just slightly disappointed that I can't hit 4.63ghz it'll only do 35x

Timings are now:

DRAM REF Cycle time of 74 crashes the system.

I was a little surprised when it just went down and down and down!!

I'll just do some light gaming again, and try benching it a little later if there are no crashes.
 
Put tCKE back to Auto and pushed tFAW down to 22 & tRW to 9 it's held up against everything, gaming, 3 runs through of CineBench, 3d Mark 2011, and several runs over Unigine Heaven 4.0 to get my graphics stable.

Is there anything else I can do this??

Your perhaps at your limit then and i wouldn't go any more, stick with what you have and just use your rig. For 8 sticks you have some excellent results there.

I'm about at the same level as you with mine, one more click here or there can cause instabilities, namely in BF4.
I'd save your profile to a usb stick, then you could look at other options. Possibly a benching profile?? Remove 4 sticks, up voltages slightly and try again.

I would, but to bench my system I'd have to drain my CPU loop as my ram has water blocks...

I've saved the profile to the bios, I'll save to a stick as well tonight... I'm going to pull it back to 129, as I can drop the vcore back down a little as well!

The RAM just kept giving and giving in terms of timings!!

But yeah, I'm pretty pleased with what I've achieved! Top 10 dual GPU for Firestrike on the board!
