Best settings for 3930k/3960x

Yep!!! And indeed those memory timings are loose!!! very loose!!! Cas 11 is more like 2800 timings on Ivy. I never use Cas 11 on SB-E. Cas 10 2500+.

I feel sad. Look forward to your timings

Just a quick question - how do you achieve cas10 then? Voltage? Something else?

Dont feel sad your Overclock is excellent. I am just saying it will not be efficient. Well you need to tune the DIMMS as a whole. Which dimms are they exactly and what part number if you know???

Could you post a memtweakit of the settings and I will look at them.
 
Small Q's for you 8 Pack (didn't want to start another thread for the sake of it)...which no doubt will get coverage in your guide :)

IMC voltage on my setup (called system agent voltage) is auto running at ~1.335v, whats the safe maximum I can take this up to? Hopefully be back clocking and benching shortly, so for now I can just work on either trying to dial my memory down to C10 or raise it to 2500+. Edit: Derp, the same part of the manual I got the below info from says a max of 1.4v SA for benching, sounds a little low given its stock voltage?

Also DRAM voltages, my manual from MSI says I should be safe enough for bench running at 1.8v max for DDR2400 - 2600, sound a little high or leave that stuff until the memory is under water?

It's ok :) I know that I need help

This memory purchased from OCUK

1.335 is way too high for 24/7 and will cause chip degradation on the IMC. At -50 I never go over 1.29 for DDR2500+ real tight. 1.4 maximum is for sub zero stuff and no good chip I have ever had needs that much. For everyday use 1.15 and for bench no more than 1.2 on your cooling. Sort that now!!!!

If your board is auto setting VTT similarly set that to 1.15 also. VCCSA and VTT are more dagerous on these chips than Vcore as the quad channel controller is so complex. Lower VTT and SA give lower core temps too.

I do 1.82 volts for bench on X79 with Hynix IC. Which is Cas 10-12-11-28 1T with very tight subs. I do cas 9 upto 2450. I can now do better than this as Ihave some new dimms but Cas 10 2400 is par for the course here.

You dont need memory under water ever really on X79.
 
Badboy this is some 1866mhz Dominator Plats at 2133mhz. Vdimm is 1.65, VCCSA is 1.05 VTT is 1.1 and the Abs are mine LOL!!. Rampage mode 1 and input all the other timing yourself. Should work well at 2000+ this. You may need to reset bios so as to force memory training with the new timings though.

 
Cheers buddy, I'll go have a fiddle now and see what I can do, I did think I had seen you/wazza mention 1.2v as an absolute IMC limit though the MSI guide puts 1.3>1.4v SA in the 'fun' setting :p
 
tbh the majority of auto volts on this board are too high, I've taken SA down to 1.14v and its fine, it was auto setting dram voltage to 1.675v too. Can you do me a huuuge favour if you're speaking to the BIOS engineers, ask them to allow decimal digit BCLK, as I can set either 102 or 103 not 102.9 (I prefer gives me a clean 2400mhz on the memory).

The one thing I will say good is if you manually set the memory MP ignoring XMP and set the timings to auto it does improve them (11-13-11-30-192-2T down to 11-12-11-30-172-1T) though it needs more volts I presume heading towards 2450mhz, random program errors and BSOD's at that.

You full on moved down towards OcUK HQ then 8 Pack or just commuting?
 
There is no reason they cant allow decimels as the X79 clock gen does. I will ask about this one too then. You want a clean 2400 what about above it man!!! Overclock!!!

Aggressive timings are good yes providing its stable. MSI need to be careful with that as TRFC and Command rate effect the Dimms stability quite abit. For your Dimms they clearly got the balance right interms of perf. For others it may not be the case especially for those with weak controllers.

I am living near OCUK in the week and returning up north at weekends essentially. The exotic cooling stuff I am doing from home too.
 
Bit of a trek but worth it :D

Yep, it only allows a 3 digit input, even if I type in 99.6 it rounds it up to 100 base, I could have the decimal with the GB board. 102.9 is just for my 24/7 clock (102.9 x 1.25 x 18.66 = nice clean 2400mhz), had them up to ~2420mhz earlier at 11-13-11-35-220-2T, just a little too slack for the extra 20mhz, but was only a rough run. Then I got greedy with the base and had to reset cmos, would appear 130 BCLK is my limit without further voltage/timing adjustments :p

Keep up the good work buddy, I told you that you were well liked around here ;)

Any chance of a bigger pic? Link it rather than
 
BadBoy just go Rampage tweak mode 1, then type these numbers down your settings. 9-11-10-28-1 Seconds-6-96-10-5-24-5-4-8 (These are fairly well tuned!!!) Thirds 0-2-3-3-3-2-1-2-3-0 and reboot. Try with blk 101.2 to force memory training of the new settings.
 
Any progress on a guide 8 Pack?

Looking forward to seeing what I really can get out of my hardware as oppose to what I thought I could get :-)

EDIT: I can see your now a man in demand so just when ever you get time! You cant rush perfection
 
Sorry to use an old thread but I am working on improving my 3 x 680 score (as mentioned a few times lol)

I will use this thread to keep you informed of progress.

I am desperate to get better TriSLI results
 
This is from 8Packs guide


"A setting of BLK skew -2 and PCI Ex CLK skew of -20 helps with stability on this format.

For cold use -3 and -30 especially with higher BLK.

Experiment with these settings -1 and -10 can also work well."



I used it and found -3 and -30 worked well with TriSli :)

Worth a try if you haven't already
