RAM Voltages/Settings using 64GB

KristopherF · 11 Jan 2013 at 17:00

Hi guys,

So to start, I am a little new, when it comes to adjusting stuff in the bios with regards to voltages etc for RAM and CPU etc.

What I want to know, is with the bellow setup, what settings should I have to enable a stable system. I am not looking to overclock the system right now, I just want a nice stable working system with the right settings for my hardware

Specs:
Motherboard: Gigabyte X79-UD5 Rev1.0
BIOS: F12
CPU: Intel i7-3930K (3.2GHz) (6Core - 12 Threads)
RAM: 64GB (8x8) Patriot Intel Extreme Masters DDR3 PC3-12800C9 1600MHz Quad Channel
GPU: Nvidia GeForce GTX 670
PSU: Antec 850W Gold
SSD1: 256GB SATA3 Samsung 830
SSD2: 240GB SATA3 OZC Agility 3
SSD3: 128GB SATA3 Samsung 830

Any help from you memory guru's would be great!

No one? :/

Just make sure you enable XMP and it will set up all the RAM settings for you. That's all you need to do

When I put XMP on in the BIOS the system failed to boot and just shuts off power, then I need to clear the CMOS to get it running again.

I've checked with Gigabyte support and they say XMP is defo fine to use with my Mobo, CPU and RAM setup :/

Having the same issue with my memory, as soon as XMP is on it won't boot :-(

Hmmm, well I am waiting for Gigabyte support to reply, should be tomorrow. Hopefully they can shed some light on it for me. If I get a solution of more info I will post it here

Have you also tried setting the RAM voltage at 1.6v? Looking around I can't seem to find the 8x8gb version of the RAM, just the 4x8gb version of it. I'm assuming you got two of this kits and trying to get them to work together? Have you also tried just 4 modules in the system as well?

KristopherF · 14 Jan 2013 at 15:30

Yeah its two 4x8gb kits that I have, I am just running 1 kit at the mo as the other has been sent back due to a faulty ram module. System is running fine at the moment.

i'm running 64gb ram and just set it to use the xmp profile and forgot about it, did need to adjust my overclock from using base block to multi only, are you running any kind of overclock at all?. oops just reread your post so guessing not, frustrating!, have you got the latest bios for your motherboard?

I haven't ran memtest or anything but the machine did near 30 hours constant rendering over the weekend so I think its stable lol.

8 Pack · 14 Jan 2013 at 22:16

XMP for a 4x8gb Kit will often not work with 8x8gb. This is because some settings trained tight with 4x8gb will not allow the system to boot with 8x8gb. TRFC needs relaxing for starters to around 296. Where as a decent kit at 1600mhz will run 196 or lower. The XMP on that kit is programmed for 4x8gb.

If you have a strong IMC on your CPU it could work but in a lot of instances it will not. HIgher VTT, PLL, Vcore and VDRAM may also be needed for stability.

KristopherF · 14 Jan 2013 at 22:31

8 Pack, I think you miss-read, XMP will not work when I only have the 1 4x8gb pack in. I have not been able to try with the second pack so all ram slots are filled as it has been sent back.

As for OC on the CPU, from what I gather it does have a slight OC due to the motherboard, making it run from 3.2 to 3.8, however I am unsure. Any idea how to make sure no OC is applied? I know most would say clear CMOS or just put back to auto settings but this is what seems to be adding the OC.

The motherboard is a Gigabyte X79 UD5 and CPU is a i7-3930K.

And just for the money shot as I am super lazy, if anyone want to tell me what settings I should be applying for the ram, then feel free!

Ram is: Patriot Extreme Master Series 1600MHz 2x 4x8GB packs (64gb total).

That's just the sound of Turbo boost, which is normal.

Just set the XMP, raise the RAM voltage to 1.6v and try that.

KristopherF · 15 Jan 2013 at 00:36

For some reason it hates XMP. Not sure why. But what I have done is go in manually.

Ive set it all too that of the manufactures specs. which is 9-9-9-24. MB had it as 9-9-11-24, aside from that I have just left everything else.

Orcvader · 15 Jan 2013 at 11:03

I take it you haven't tried playing with the voltages yet then?

KristopherF · 15 Jan 2013 at 11:56

no i just left it at its defualt specs of 1.5v

As I mentioned before, raise the voltage to 1.6v and see if it boots on the XMP profile then.

KristopherF · 15 Jan 2013 at 23:05

Hmm okay, ill give it ago tomorrow and post my findings. I will be running this with 8x8gb soon tho so XMP would not work will it? If I read what 8 Pack has said right anyway, I think.

Im just trying to tweek my CPU at the mo!

jnmann · 20 Jan 2013 at 15:32

Did you get anywhere with this Kristopher?

KristopherF · 21 Jan 2013 at 15:40

Yeah.... About to post a new thread as I thing my ram is goosed!

If i manually enter the rams settings, boost the voltage to 1.6v and enable extreme performance then Its pretty stable.

By that I mean no BSODs with OC, Intel Burn will pass on all settings, except maximum, which it only passes two runs.

However I am running each of my ram sticks one by one, and using memtest86 to what the deal is.

I will post up a final list of results in a new thread.
Perhaps close this thread? Im 95% sure I have bad ram.
