Hi all,
I have purchased a ga-x79-up4 motherboard , Intel Core i7-3930K C2 Stepping (SR0KY) 3.20GHz (Sandy Bridge-E) Socket LGA2011 Processor, Corsair CMD32GX3M4A2133C9 32GB (4*8GB) 1.65v 2133MHz RAM, Radeon HD 7970 GPU.
It doesn't boot, at all. The fans spin up but there is no image on the output from the graphics card, hence I can't get to BIOS. Annoyingly I don't have access to an internal speaker to listen for beep codes. I actually bought two of the graphics cards but decided to get the system to boot with just one as an initial test to make sure that everything was ok before I put the second one in, I can be pretty confident this is not a problem with the graphics card as when I replace the first one with the second one I get the same issue.
So this leads me to think maybe its a RAM or CPU issue. Noteably the RAM I chose does not appear on the qualified vendors list for this motherboard. I also notice only now that the ram is rated at 1.65v, will the motherboard realise this and supply it or will it panic and do nothing like I am observing?
I have tried using just two sticks and using just one stick of ram but with the same results.
Perhaps someone can also help me with this, if I boot the system with no ram at all, what should happen? In my case I get the same thing, no output from the GPU, but really I think I would expect a message like 'No RAM' or something.
Is it the case that this motherboard runs at vdimm 1.5 by default, if so, do you think the ram should work anyway just at a lower rate than the advertised 2133MHz, because I am not seeing that.
Is there a way to get the vdimm to 1.65 without going through the BIOS (a jumper setting or something). Am I even wise to try? I have read elsewhere that the CPU would not like that.
Thank you for your time.
Kindest regards,
M
