Hey guys. I have a couple RAM related questions. I am currently running THIS kit on my E770 X58 Classified 3. 
 
1. I have had trouble getting it to be completely stable at the stock timings and speed (2000mhz 9-10-9-27 @1.65v)
Which voltage is it that stabilizes the memory controller and what would I advise I run it at? I am thinking if I have the correct voltage I can get this RAM to be stable. The RAM is currently at 1600mhz and running fine, I would just like to be able to get the extra speed out of it.
 
2. I would also like to bump up to 24gbs of high performance RAM but legacy modules like these are hard to come by since X58 is pretty old. Can anyone point me in the right direction. I'd be very happy to find another one of these kits for a good price and run 6x4gb modules. I have heard it's pretty difficult to get these boards stable with all 6 DIMMs filled at 24gb. Would I be better off using dual channel modules and less DIMMs?
 
Thank you

Thanks. I will set that when I get home and see what happens. The RAM is pretty stable at 2000mhz for the most part. I only have a few crashes far and in between. I'm hoping setting the CPU VVT correctly will be the final little bit to make these modules rock solid. Setting my Command Rate to 1T may help stability quite a bit and I doubt there is that much of a performance difference between the 1T and 2T

In terms of upgrading, all I can find is 1333 in 8gb modules. Looks like I may be stuck running all 6 DIMMs at 1600mhz. From what I'm reading nobody has had any luck getting 2000mhz with 6 modules. This is all Newegg has: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&IsNodeId=1&N=100007611%20601190327%20600052011%20601275375

I may just stick with 12gb of fast memory until I absolutely have to upgrade. For now this old system is handling my 1080 and everything else just fine.
 
I will adjust the VVT and report back. Are there any other voltage settings relating to memory? The modules are currently at the specified 1.65v. I know the CPU OC is rock solid.

1T is faster and maybe less stable than 2T on the memory, and there is a difference. Will you see the difference in everyday usage or just benchmarks??? So if you have to get it stable go with 2T.
I have used 2 sticks of 8gb G.Skill 1866. I would think two 8gb dual rank dual channel, would be close to three sticks of single rank triple channel. X58 can't do quad, but on my x79, quad channel would be better than dual channel, dual rank memory. Not to confuse you...
At least it seems with memory intensive BOINC primegrid work units.
How that equates to gaming????
If you can't get the speed, tighten timings, including T2 down to T1*. (*maybe less stable)
Good luck

I take it the settings are working for you?
 
Heavy-Hemi  I think he has an i7-970 CPU. In his sig is a CPUZ banner, real small print, but looks like i7-970 to me.
 
I do believe this is the memory he has,  its what he linked to.

Yes, everything has been running smooth. The VVT seems to have done it. I was giving it too much voltage at +300mv. As you can imagine CPU temps also dropped a bit which is always welcome. If you click that banner it will have more specific specs. 

Correct, I am running a 970 @4.2ghz. 200 BCLK 21 multiplier. It still doesn't look like 12gb is an issue yet. I may just put off upgrading to 24gb to stick with fast 12gb.

Good glad to hear it. I myself try to keep my CPU and VVT at or below 1.35V . For tenps and longevity.
12gb most of the time is enough. If you need more I would consider another stick of what you have for 16gb or two 8gb dual rank.
Honestly in this stage of the game, I would rather save my money for other upgrades in the future.
 
Good luck with it.
 

Agreed. I'm just going to ride out this X58 until the wheels fall off. It has and continues to be an excellent system. All my benchmarks are up there with current chipsets. I've been very impressed with X58

CPU VVT, can be raised, set it to +150mv. I would not go much higher than that. That is = to 1.35v
If you can not get it faster, try tightening the timings, 8-9-8-25, or 7-8-7-25  first  2T  then try 1T
You can try 3 x 8gb sticks, most 8gb sticks are dual rank. Triple channel dual rank is a good thing.

Very good help there.      

Thank you guys for the BR. More than happy to help.
