Can a CPU cause RAM not to work

[Drake5]

My motherboard stopped working recently so I had to replace it. I replaced it with one I got from ebay, one of the RAM slots on the motherboard didn't work. I was then sent a replacement and I had the same issue.

The RAM is fine

Can a faulty CPU cause one RAM slot to not work? If I put RAM in the slot closest to the CPU, I won't get a display until I take the RAM out and move it over to the other slot

Could have a faulty IMC at a guess so I am going to go with yes, yes it can.

You generally have to fill memory slots in a specified order. What does the manual say?

 

[Drake5]

There's only 2 ram slots

Try and loosen off the cpu cooler, doing it too tight can cause these issues.

Could you please tell us the model of the board and processor you have, then we can help more.

Could be a bent pin in the cpu socket

Model of the board is Asus P8H61-I LX R2.0 and the cpu is a 3570k

Have you done the simple thing of swapping the RAM sticks around? No offence at suggesting something so obvious.
The memory controller is on the CPU but the mobo has a lot of RAM related tech so it could be either.
The chances of two faulty mobos is possibly more likely than a faulty CPU I imagine!

I've swapped the ram sticks around

The guy who sent me this board assured me he fully tested it and confirmed both ram slots work

I'd be tempted to purchase a CPU from CeX for £1 or £2 + postage and see how you get on with that:

Well the board should fully support the CPU, from the very first BIOS, so that covers weird microcode issues.

Check the CPU socket for damaged bent pins, you might need a bright LED (phone torch), and possible a small magnifier, but if they are all straight you can tell as the light will reflect evenly.

If you are trying to use 2x8GB sticks of RAM, then you might need to upgrade the BIOS, since QVL on the 8GB sticks from 2012 was patchy at best. The latest BIOS is 1106 and here is a link for it

Bios updates for this board won't work as it's an RM board so you have to use there bioses directly which I don't think they supply

Are you sure about that? I had one recently (Think it was a Viglen) that I flashed successfully with stock BIOS.

Yup, when I try it just says 'invalid'

Have you tried cleaning the underside of the cpu with some alcohol? Long shot but there may be some residue preventing proper contact.

Just use DOS based flash and a /f or what ever the force flash switch is for that program. Obviously make sure you actually have the right board BIOS first.

I managed to find the bios, flashed it and I still have the same issue

I guess it's the CPU
