<div>
to be sure, you have to try ... nobody can guarantee a thing<br />
most probable is mobo bad, and backward stick bad.<br />
you can test with the other stick alone first.<br />
<br />
and mobo fuses are non-existant for more than 10 years now imho...
</div>


<div>
actually nobus, mobo do still have fusible links there just not servicable.
</div>


<div>
The fuses may also be a built in feature of the regulators, you need to have current protection for fault conditions. Many modern PSU have the ability for very large currents up to 25A and if a fault path is not broken quickly a fire could easily result thus it is esentiall to have fuse like devices. But yes your right there has not been the traditional type of fuse on a MOBO for many years, most likly to prevent self-servicing and reduce cost.
</div>


<div>
&gt;&gt; &nbsp;The fuses may also be a built in feature of the regulators &nbsp; &lt;&lt;&nbsp; never heard that<br />
i think you are confusing a fuse with overvoltage, and over current protection, which is an entirily different matter.<br />
However &nbsp;- if you can point me to an article about a fuse on the mobo (inbuilt or not) i can always learn ...
</div>


<div>
If the memory module is faulty, it just won't work. I think there's no chance to harm the MOBO. Feel free to give it a shot; the following is a link to an image for a memory module that has been put backwards and worked fine after that for a while.<br />

<div>
Actually fuses are a form of over-current protection, eg a high current will blow a fues. Motherboards do have this feature by using various different means, perhaps using polyswitches or current / power management ICs. either way there is generally limit where the component will not reset (eg. burns out). By no means am I suggesting that the user should attempt to repair the motherboard as this could indeed be dangerous. Without overcurrent protection for fault conditions the mobo would never pass the electrical safety certification. <br />
<br />
Have a look at <a href="http://se.asus.com/news_show.aspx?id=11350" rel="ugc">http://se.asus.com/news_show.aspx?id=11350</a><br />
<br />
&quot;ASUS motherboards are designed with an installed circuit that acts like fuses and circuit breakers to detect an overcurrent condition when the current reaches a value that will cause an excessive or dangerous temperature rise in conductors  and in doing so, protecting your external devices, ICs and the safety of the users themselves.&quot;<br />
<br />
Anyway I don't particularly wish to argue over small details, and hence go off topic. If you want lets agree to disagree and get back to the question.<br />
<br />
By the way sorry, If my tone sounds nasty, worked 60 hrs so far this week and I still have probably another 16 hrs to go.
</div>


<div>
@MoatazGod unfortunately you can never be sure, supply faults can result in clamping diodes shorting to the rails. But I agree it is a fairly low risk. I just provide no warrenty. Of course is there any sign at all of damage by close inspection I wouldn't try it, but unfortuantly the damage may not be visible without an electron microscope.<br />
<br />
So what I would do, Replace the mobo try to boot with the non-reversed ram. thus check to see if PSU and all other components are ok. Then once its all up and running try the other stick of ram.
</div>


<div>
&gt;&gt; &nbsp;with an installed circuit that acts like fuses &nbsp; &nbsp;&lt;&lt; &nbsp;that means there are NO fuses, as i said, but circuits to protect. &nbsp;And i do not find your tone nasty, since you did not speak. I just wanted to clarify something.<br />
Tx for the explanation anyway !
</div>


<div>
Ok yes, sorry ok I never meant actuall fues as the low temp wire. I tend to try and simplify terms as I'm used to dealing with people with little knowledge about electronics and comps at work and thus it has flowed on to here.
</div>


<div>
If the magic smoke has been released from the omnipotent component, all is lost.
</div>


<div>
Sorry, couldn't resist :-)<br />
<br />
Personally, I wouldn't try the smoked ram module in any other computer as it may cause problems with the board. &nbsp;
</div>


<div>
The other ram module that was in there correctly should be tested with memtest.<br />
The reason I wouldn't use the other smoked module is because there is always the chance that something fused in it and that could cause another overvoltage to the next motherboard you try. It's a gamble.
</div>


<div>
Yes I agree, its a gamble. realistically the value of ram is cheap compared to the other components of your system so perhaps it is best to cut it as a lost, and just replace the module.
</div>


<div>
Thanks guys ;)<br />
I'll play it safe and keep the backwarded (?) RAM out of it.

<div class="content wysiwyg-content">
Yes, people do put DIMMs in backwards but, no, I am not an idiot.<br />
<br />
Synopsis: There are two DIMM slots on the MOBO. There were two DIMMs already in it and I was replacing one of them. &nbsp;I bought another DIMM of the same type and put it in backwards. &nbsp;How? One side is slightly in the slot and CLAMPED in! The other side also clamped in somehow too. &nbsp;This needs to be redesigned. &nbsp;Anyways, as soon as I pressed the power button, I heard a pop and nothing came up on the screen. &nbsp;No boot, no POST. &nbsp;So I freaked out and upon looking closer noticed that it was backwards. &nbsp;I put it right and, of course, no go. &nbsp;I took it out and put in the original one. &nbsp;No go. &nbsp;Crap, obviously fried the board. So.....<br />
<br />
Question: Even though I am going to replace the MOBO, is it safe to try to use the DIMMs that had been in there when it shorted. &nbsp;I realize the DIMMs may or may not work but I want to try anyways. &nbsp;But could it be damaging to the replacement MOBO? &nbsp;I was thinking, if I shorted the DIMMs, is it possible to short the new MOBO by putting them in?<br />
<br />
Please don't make fun of me, I am NOT a noob. &nbsp;That is the pathetic thing.<br />
<br />
Thanks,<br />
