ASUS X79-Deluxe with 4960X CPU 32GB memory choice…

[BruceWB]

I have the just released ASUS X79 Deluxe on order along with a new 4960X 6 core processer and will be overclocking. (No, I couldn’t wait for the Rampage Dark)

 

This is Ivy Bridge-E motherboard, the 4960X is a one stick per channel CPU but now formally supports 1866 memory. This is also a 32GB build.

 

This is a workstation build; CAM, tons of high tolerance math.

 

The qualified Dominator Platinum selections include:

 

2400 - timing 10-12-12-31 – 1.65V

2133 – timing 9-11-11-31 - 1.65V

1866 – timing 9-10-9-27 1.5V

I’m not shooting for 2400 of course, but if I can gain an advantage in timing down the line that works. Any suggestions or alternates would be very much appreciated.

 

Thanks in advice.

You can use any of the Dominator Platinum's, VengeancePro's, or the regualr Vengeance line would be the three best choices. As for speed goes since this is a workstation I wouldn't even bother with adjusting timings because the gain will be very little to just getting a 32gig kit at 2133mhz no matter the CL. You'll not only get a huge performance boost just from the amount as well as a little more out of the RAM.

 

Really, your best bet would be to OC your CPU a little vs your memory. You'll see much larger returns in performance than you would with a higher memory overclock.

so where would the choice of dominator platinum be a clear benefit over vengeance?

[peanutz94]

The Platinums would allow for higher OC's,and are market as such. Where as the vengeance is more of the "gaming memory" but given the same speed and timings, apart from aesthetics, there would be no performance gain between them.

Thanks peanutz,

 

I should have explained this a little better: “This is a workstation build; CAM, tons of high tolerance math. “…

 

The CAM application we are running brings a 2600K (not overclocked, Vengeance 16GB, and Intel SSD) to what seems like a crawl when computing .0001 mill tool paths, maxing out all 4 cores and using as much as 12-14GB. The necessary jump in the tool paths from .001 tolerances to .0001 has increased the calculation time the order of several magnitudes which is now taking upwards of 10 minutes.

 

This application only needs a mid-range GPU so I will be using a GTX 760 and probably a 212 cooler.

 

Over the weekend I finally found a review of the X79 Deluxe and 4960X, using Vengeance 1866, 9-10-9-27 with some of the following results:

 

4.5GHz at 1866 stable, 4.6 at 1722 stable, and unstable at 4.7 1600.

 

Realizing all the gray areas including the 1866 CPU upgrade, as of today there probably isn’t even a “best guess” answer to my question. But if there is I’d of course like to try it, and then again maybe I'm stressing out too much over this as I would be very happy at 4.6 and 1722..

Your right. When you get into overclocking nothing is a given, even if the hardware is the exact same. An you don't need to upgrade your CPU to run 1866mhz memory. Your CPU should be able to run it just fine as well. It all boils down to the strength and or weakness of the memory controller located in the CPU itself.

The CAM application we are running brings a 2600K (not overclocked, Vengeance 16GB, and Intel SSD) to what seems like a crawl when computing .0001 mill tool paths, maxing out all 4 cores and using as much as 12-14GB. The necessary jump in the tool paths from .001 tolerances to .0001 has increased the calculation time the order of several magnitudes which is now taking upwards of 10 minutes.

In your case your going to see your biggest returns (as far as the memory is concerned) with greater capacity in itself. Extra speed is just a boon.

 

I would seriously consider getting 32gig 2133mhz memory. It's a mediochre overclock as far as memory is concerned with your CPU and then try and get what ever you can out of the CPU. If you have to sacrifice memory speed to gain more on the CPU then that's okay too.

 

But your right , there really is no way to give you a best answer or best guess. I have seen CPU's that wouldn't overclock at all, and I have seen some that far surpassed the top of the line models./ shrugs It's just a total crapshoot.

 

Have you by any chance thought about messing around with a RAMDISK? That might be the solution your looking for.

[BruceWB]

RAMDISK, I haven’t considered it, but thanks for the suggestion.

 

According to the application guru it seems the bottle neck is the CPU and just a good SSD does the trick. I’ve ruled out Raid 0 and PCI-SSD for various other reasons too. I will be using a Samsung 840 pro.

 

However according to the application website the minimum requirements for free space is 5GB. I generally consider minimum requirements a waste of time however since I’m covered with 32GB maybe a 8GB RAMDISK or thereabouts would be worth testing on some difficult tool path calculations. On the other side, this is a workstation build a couple states away.

 

CMD32GX3M4A2133C9 looks like a go.

 

Thanks for the RAMDISK idea.
