Quad Channel Memory

crayseal15 · Jan 3, 2015

I have an Alienware Aurora R4 from about 3 years ago. It is an x79 Board with a 3930k processor. As far as I know EVERY x79 mobo is capable of quad channel 2133 mhz ram. Being that it is Alienware I do understand that sometimes all specs arent viable, but based on x79 and 3930k I should have no problem with 2133 mhz ram yes?

Look in the BIOS and see if you can make adjustments to the DRAM - if it's locked may be stuck with a max of 1600 or 1866 and what Auto can configure the DRAM to.

Ther seems to be plenty of optioins, There is also the "XMP" on/ff which seems to be associtated with Quad. Extreme Memory Profile I think.

Then should be able to utilize it

I hope so. Would rather be sure though.

A few more nights an we will see!

I received the quad kit yesterday after some tampering I could get it to work @ 1866 with no trouble. Realized it just wouldn't boot with XMP enabled. I also had to set the timings to manual and input all that correctly. So yeah it registers under quad channel and all but I can't get it to boot past 1866. I seen there was 9 DRAM Frequency option that started out at 600 or 800 mhz and 1866 is at frequency 7 so I was guessing 2133 was at the 8th setting but no boot when i choose 8 or 9th frequency but all below that boot no prob. I'm not sure if there is something else that would have to be manipulated but until I can get more info I'm gonna settle with 1866. I have read some posts where ppl are running the quad 2133 but it's other brands whereas people using corsair seemed to have no luck hitting the 2133 setting.

For 2133 will prob need a bit of an OC on the CPU also and to raise the VCCSA (System Agent voltage) t maybe 1.2 or so

i was going to post a screen of the cpuid but I don't know how :X

Tradesman1 · Jan 7, 2015

Take the image and post it on a free image posting site and stick a link to it in your response

crayseal15 · Jan 7, 2015

Yeah I considered I would have to change something. Just changing the timings and other stuff was new for me so not sure of where to even start going the route of upping the cpu. Other concerns are the factory overclock, I've tampered with it some with not great results, having to reset cmos to boot a million times but I guess I just ended to read into some more. I see the "Core Voltage" in CPUZ listed at 1.336 if that's any relation.

I see on the screen with the ram info it lists JDEC 1-3 then XMP with 1066 so that would be the 2133 setting I assume. But JDEC #2 is 533 so 533x4 is 2133 also so yeah, I'm underknowledged lol.

no idea

Tradesman1 · Jan 8, 2015

Did you enable XMP in the BIOS, the first screenshot shows you at 933 or 1866 (double data rate) what does CPU-Z show in the memory tab

It seems when I enable XMP in bios the computer wont boot with this ram. Then i hav eto rest bios and pop in the old ram to reset all the timings and put the new ram in again.

Tradesman1 · Jan 9, 2015

They may never have updated the BIOS to correcttly set the sticks up, could try manually (will need an OC on the CPU probably

crayseal15 · Jan 10, 2015

what type of oc is needed on the cpu to make it work then?

Tradesman1 · Jan 10, 2015

Try setting base to 3.8, 3.9 around there, might simply go to 4 then can lower from there if you want

crayseal15 · Jan 11, 2015

well it was already oc'd to 3.8 from 3.2 that second screenshot showed the multiplier at 38 and speed at 3799.11 I can try higher. I'll also look into the voltage you were talking about.

crayseal15 · Jan 11, 2015

I upped the VSSCA to 1.2 Didn't see any change in the ram that I can tell. Only thing I noticed was was the clock speed multiplier seemed to be at 12 from 10.
