Yes maybe but the CPU does not. You need a Xeon with a Xeon Chipset (C602 or so) to use it.

You can't use Registred ECC RAM with a Core i7 CPU, even if the Motherboard allows it, its disabled in the CPU.

HI everyone,

 

I need some help with this plz and no criticizing or judgement needed, thx.

I have bought an i7-4820k from someone a while ago, i found out afterward that most branded lga2011 socket motherboard are very expensive if i could even find one. So i went and looked for one on amazon and newegg, where i found from amazon, a chinese brand. I looked for some reviews on the web and found a lot of positive feedback and saw on one youtube video that it worked fine so i ordered it. The description said that the motherboard was only compatible with a REG/ECC ram so i bought a samsung brand from newegg. After receiving everything and assembled it, I powered it on, but no graphics is appearing on screen, I tried swapping the ram to another slot, still nothing. So is it the motherboard problem? Everything seems so to be okay, fans and lights are on. My components are, of course the chinese x79 OCAMO motherboard from amazon, i7-4820k, samsung 8GB REG/ECC DDR3 1600mhz ram, 500W PSU. I tried different GPU, i have a GTX760, i also tried with an old GTX card with HDMI plug, but just nothing is coming on screen.

So any idea on how i can make this work?

Do you have non ECC ram lying around?

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k - EVGA Z370 Classified K - G.Skill Trident Z RGB - WD SN750 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G3 650W - dual booting Windows 10 and Linux - Black and green theme, Razer brainwashed me.

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

Already tried with an 8GB Patriot non ECC ram, the motherboard seems to be looping on/off with it, but with the samsung ECC ram, it stays on and not looping, it just won't output anything on screen.

The CPU doesn't support ECC. You'll have to find a xeon instead.

Xeon e5649@4.4 GHz on Asus Rampage II Extreme or Gigabyte x58a-OC (whatever I feel like to set up at a time) , 6x4 GB Kingston HyperX 1600, Gainward GTX 670 Phantom, Samsung 840 Evo 240 GB, BeQuiet L8 530W
