1196437 2011-04-22 10:03:00 Hi, I recently mistakenly inserted my RAM Back to front :mad::badpc: And after that my motherboard stopped working. So I got a different one that worked and tried using it with my damaged ram. When I inserted 2 of my "damaged RAM" I got continuous Beeps. But when I put them in separately they worked fine. I did a memtest and everything seemed fine. I need help!:confused::confused::confused: PC builder (15482)
1196438 2011-04-22 10:45:00 Inserted it back to front ??? :eek:

It MUST have been forced, as its almost impossible to put them in backwards due to the off set alignment slots in the RAM.

Chances are very high you have short circuited, or damaged the board in some way.

1196439 2011-04-22 11:44:00 Just adding to my above post - if the RAM works OK as singles, but fails when both are installed in a working board, the RAM as well will be damaged. What will be happening is when in singles the fault wont be showing, but as soon as it tries to run in dual core, or any other configuration the faults show.

Memtest doesn't always show when theres a fault with Memory, its not fool proof. Actually had this happen a couple of times - other memory testers like MS's one, may show a fault, memtest didn't, or vice versa.

1196441 2011-04-23 03:59:00 Wow, I've tried installing RAM backwards only by accident when working in poor light. You must have pressed like a demon to get the clips to seat.

On the other hand, RAM often needs to be pressed like a demon to get the clips to close, so I can't fault you for that one!

I would assume the motherboard and RAM slots bowed in order to allow the ram card to be accommodated.
Apart from perhaps damaging the RAM slots (and more likely the RAM cards), I would not have expected the motherboard to be otherwise corrupted. In fact, it'd be worth trying the original MB with known good RAM, as I'd gamble on it only being the RAM that suffered.

However, if the plastic seat the RAM goes into is no longer flush with the MB along the entire length, then it may well be poked.

My brother did this once. Killed the RAM but amazingly didn't kill the motherboard. Yep, he SHOVED it down. Hard.

Once you have your replacements remember, if you have to use even slight force, it's not lined up right.

1196443 2011-04-24 06:34:00 Used a MS memtest but shows its all fine. But doesn't work as a pair :( Used another piece of ram with the damaged one and it works. Not sure what's wrong. PC builder (15482)
1196444 2011-04-24 06:41:00 This may seem an ignorant question, but I take it their speed and size are exactly the same, eh? Also, when you initially put the module in backwards did you actually boot up before you realised (i.e. power was applied at one stage) or was there no power applied at all during the whole process? mookster1 (15854)

Not always....

A few years ago my friend and I were upgrading his PC... he had 2x 512MB sticks of RAM and upon powering up it showed only 512MB instead of the usual 1GB

Turned out the RAM slots were damn tight, had to push like a madman to get them in all the way. One stick hadn't gone in properly first try and I guess wasn't making contact properly and thus not detected.

Only board I saw that ever had that problem. But the sticks were definitely not backwards!
