Alright I'm not new to forums and I know how annoying it is to have newbs posting without searching, but I can't find anyone who has this problem so any help would be appreciated, because I think I may be missing a glaring problem. <br />
<br />
I got an insane deal on an FX55, I put it in my A8n-SLI dlx and it instantly gave me memory problems. I've been running 2GB wintec AMPO pc3200 in it perfectly fine until I pop in this cpu, now I can't get more than a gig in without it freakin out. I can put it in any slots, and still get it to show 1 gig but when i put in another, still only 1gig, and then when I put in the fourth 512 stick it won't boot, says system failed memory test when you boot. Is there something with the FX55 that doesn't let it run this memory at 2gig dual channel or something. I RMAd the board, got another one and the exact same thing happened. Thanks in advance for the help!!! This forum is tops!

Some people have problems with AMD and 4 x 512mb sticks of ram. I have no problems at all, but it could be because I'm not using a high-preformance CPU, or a high FSB.

</div>Everybody "essentially" has problems with 4 sticks of RAM in your AMD system. It automatically downgrades the memory speed (Some CPU revisions) to DDR333 speeds and puts it to 2T (All CPU revisions), both of which can make the system run slower.<br />
You might have some RAM sticks which doesn't support either DDR333 speeds or 2T speeds.<br />
<br />
Secondly, the memory controller is located on the CPU at AMD's latest sockets.

it all ran fine at 2gigs with my 3700+ is there something different with the FX chips or something I'm missing and is there a way to fix this in the bios. I went it and switched it to manual instead of auto and just left the timings at 3338

</div>I say "some" because I have no problems at all. I get slightly better benchmarks with 4 x 512mb than with 2 x 512mb. Gaming, I do much better with 4 x 512mb, then with 2 x 512mb.

Hi and WELCOME to theforum <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile"><br>
The FX may need a voltage increase for the memory controler.<br>
I'm wondering if the 3700+ and the FX have the same version memory controler!

Could you post what the stock number was? (The one on the box, often [3 letters]3700[some more] or for the FX [3letters]FX55[some more])

I upped the vcore volts to 1.62 and still nothing, or were you wanting me to up the memory volts?

It's quite simple really, you require a Bios update by the sounds of it

Do you ever check for the peg link?<br><a href="http://assets.overclock.net.s3.amazonaws.com/2/21/21e4402a_vbattach34355.jpeg"><img alt="LL" src="http://cdn.overclock.net/2/21/525x525px-LL-21e4402a_vbattach34355.jpeg" style="width:525px;height:394px;"></a>

I have no idea what the peg link is. I changed everything to normal settings per the bios. I'll try that.

I changed the peg link to normal and disabled and it still didn't work, and now the slot is bad because I just put one in there and it was giving me a memory test fail. This happened on my last <br />
a8n-sli too, any chance my case is ground it out, and is the board ruined if so? I am getting my RMAd one back on monday so I don't want to ruin that one too.

bumpin this for any other ideas, how do you know if your power supply is going bad, I checked the bios and everything is just slightly low e.g. 12v is at 11.97 and so on any clue?

i wouldnt worry about it not being exact on the numbers, look for fluctuations in the numbers like if the numbers are going up and down while your jsut sitting there not doing anything<br><br>
now are you saying that your dimm slot is bad because your board is grounded out or something, because every asus that i had a grounding problem with wouldnt let me boot into even the bios

well i had this same problem with my last a8n-sli deluxe and my rmad one comes tomorrow and I don't want that one doing the same thing, how should I make it so the grounding thing isn't a problem? Also my 7600GT had one of it's DVI plugs go bad, I don't know whats going on with this board but it's not good.

Software is inaccurate when measuring voltages due to resistance. The only way to be sure is to get a voltimeter but, generly, the actual voltage is a little higher then the software reported. Like my 12v:software said 11.8 but meter said 12.07.
