Hello.
 
I've bought a new machine and can't get it to boot. The error code is 55 (memory not found). I've tried booting using 1 RAM stick, but I still get the same error. I've checked the CPU seat and there are no bent pins. I don't have any spare parts I can test with.
 
The memory I'm using is Crucial Ballistix Sport DDR4 4GB (Part Code: bls4g4d240fsa.8fadg). I don't see this part listed on the support page, but there are ones with very similar part codes. Could that be the problem?

Yeah, I heard it snap into place. I'm pretty sure it was seated properly.

Crucial says that RAM is compatible with your mobo, see Will it work with my system..But, you might need a BIOS update from EVGA for the stuff to work if your board has the original/an older BIOS..There have been some BIOS updates to improve memory compatibilty, improve CPU overclocking and various other bug fixes and enhancements..I know that don't help you at the moment because the board won't even boot..You could try clearing CMOS using the second method here, or find/borrow a stick that works so you can boot and flash the BIOS, or take it to a PC repair shop and see if they can flash it for you for a few bones..My guess is that once the BIOS is updated to the latest it will work, hopefully..Good luck.

Try loosing up your cpu cooler a bit.

There's a clam shell you can open that contains the BIOS chip right below the 24-pin connector that might say on the chip what version it is, but don't take that as proof because an older/original version could have been flashed to a different version prior to shipping without changing the chip and info on it (if any)..Open it and see if it says anything on the chip..Only way to be positively sure is to get into BIOS or the OS.
 
Crucial lists their RAM, specs and compatibilty tool here..If you can't find any joy, get ahold of Crucial customer service/support for help.

I don't know exactly what Crucial part numbers/extensions mean, you'd have to search or call/email them..Maybe get ahold of Crucial and see if your exact part number of RAM is/has been tested compatible..According to your mobo manual, slot one is the primary slot and is required be populated (or your board most likely won't boot)..You can use only one stick, installed in slot one.

Hi Antilurker77,
 
If you are continuing to have an error then please email me at chrisb@evga.com and include the registered serial number for your motherboard. Once I receive your email I can assist with having a BIOS chip with the latest BIOS version mailed to you to try and see if that helps?

Okay, Crucial told me that the stuff after the number just signifies what kit they were sold in. I bought a card and am hoping for the best...

Okay, even after installing the latest BIOS I can't get my old RAM to work. The machine loops through these error codes: 00 19 4C 31
