System wont post

System is as follows:

Intel i3-3240 processor

Kingston 128g SSD

Coolermaster 550w power supply

Asus r9 270 OC

8gigs G skill 2133 ram (from previous build)

Asus p8p67 motherboard (from previous build)

Corsair 600t white (from previous build)

 

Just finished putting together a new system for my brother using a bit of hardware I had sitting around. For some reason the system wont post. I have tried clearing CMOS, reinstalling ram and using memok switch but the system still hangs. The diagnostic board shows a 55 or ss code which isnt in the manual and the diag_mem LED stays on solid.

 

The ram was literally taken out of my personal PC which was running 5 mins before I installed in new system so I cant imagine that its bad ram.

Motherboard was working in a previous built (a few months ago) fine but the CPU is brand new, any way I can narrow it down??

I cant seem to find what code 55 means :P

Error Code 55 is No memory installed. I would suggest removing the ram modules, then install one only in the first slot, ensuring its seated properly. Go through the slots till you get a post.

 

If you don't get a post, See if the mem ok button helps when one dimm is installed

 

Also check here to ensure your memory is supported by that board. It should be.......

MOBO: ASUS X79 Pro CPU: i7 3820 Ram: Corsair Vengence 32Gb 2133mhz (8x4) GPU: 2 x Sapphire R9 290 in X-fire PSU: Seasonic G series 750w Drives: 1 x 750 gig WD black, 3x WD Black 1TB, 1 x Segate Barrcuda 1 TB, 1 x Toshiba 2TB, Intel 520 240gig SSD Case: Enthoo Primo w/ Green and Blue LED lighting.

Just finished checking all slots with one dimm and pushing mem ok. Still did exact same thing.

You may have gotten some bad ram. if you have any other sticks laying around try them. And also try each stick one at a time.

Case: Phanteks Evolve X with ITX mount  cpu: Ryzen 3900X 4.35ghz all cores Motherboard: MSI X570 Unify gpu: EVGA 1070 SC  psu: Phanteks revolt x 1200W Memory: 64GB Kingston Hyper X oc'd to 3600mhz ssd: Sabrent Rocket 4.0 1TB ITX System CPU: 4670k  Motherboard: some cheap asus h87 Ram: 16gb corsair vengeance 1600mhz

I literally had to turn off my one computer that the ram was installed in (and obviously working) to take it out and put it in the new system, I dont think that is what the problem is

Do you have any other ram modules you can test with? Could be a ram incompatibility.

 

I have a Dimm at home where is will work in every board I have except one. Yet the manual states it is compatible. go figure

OK, So the ram is fully seated (heard two clicks, one at either end)? And your new CPU is in correctly? All the case stand offs are not shorting on the back of the board?

 

Finally if all that is good, try clearing the bois, and give that a go.

 

Edit: I've done a little looking around, this fault can also be cause by bent cpu pins, and damaged ram socket pins. Please check both.

Ive re set the cpu and ram more than once, tried clearing bios also, going to take mobo out of case tomorrow and try it just on an anti-static bag. If it doesnt work Im going to guess it must be something dead on motherboard and go from there. Ill update either way.

 

Thanks for the help max /cheers

No probs mate. Let me know how you go.

 

Also, I'd try it on the main board box, before the anti static bag.
