Hi guys.<br />
<br />
I think I've been Ebay stitched up AGAIN.<br />
<br />
Just paid £135 for 2Gb Crucial Ballistix RAM, fitted it just now, and PC will not boot. I've lowered my Voltage and speed (2.6V / 220MHz).<br />
<br />
PLEASE TELL ME I HAVEN'T BEEN HAD <img src="/images/smilies/mad.gif" border="0" alt="" title="Mad" class="inlineimg" /> <br />
<br />

Have you reset your CMOS?

Yes, reset the CMOS. Changing ram *usually* requires a CMOS reset, as rams run at different timings, and if the ram you are replacing has different timings then the new ram in some cases your computer will not boot. Good catch MjrTom.

Thanks, If all else fails a CMOS reset usually fixes these types of issues <img src="/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" />

Ok, all done - and nothing. Still not booting.<br />

Can't even get into BIOS, but all is fine again when I put my old memory in......

Try booting with just one of the sticks, then try the other. Also, make sure you are running them in dual channel (same color slots).

</div>I don't know, BIOS default. I cannot get into BIOS with new sticks to check!<br />
<br />
Dual channel confirmed, and tried booting with one stick. Each still not booting.

Try going into the bios with your old ram, and manually setting the ram timings to 3-6-6-8, 2T @ 2.6 volts. Then try installing the new ram. If it still doesnt work then it would appear you recieved doa ram. You could also try updating your bios, though I doubt that would fix your problem.

<br />
Doing that now.......

Well set it to these timings to rule out what he has said, RAM can be really picky, When I changed my RAM I had to do that before it would even boot.<br />
<br />
Mine has an SPD of 2-2-2-5 @ DDR400 2.6v but would not boot at this. I needed to change the timings to 2.5-3-3-7 at 2.6v with the old memory then go back into the BIOS once booted and change the timings to SPD and increase the voltage to 3.2v (not that you need to increase your voltage this high, I have "special ones")

Try increasing the voltage to 2.8V instead. That is the general limit for RAM chips.

</div>Yep 2.8-2.9v is the limit for Micron 5B G chips that these sticks use <img src="/images/smilies/wink.gif" border="0" alt="" title="Wink" class="inlineimg" /><br />

not to be the bad guy here, but it appears that you bought either overvolted or overheated, or just burnt ram.

Last ditch effort would be to update the bios of the mobo. Sometimes updating the bios can solve motherboard/ram incompatibilities. I would give that a shot, and if that does not work it sounds like you recieved bad ram. In that case contacting the seller is the only recourse unfortunatly. Sorry to be the bearer of bad news.<img src="/images/smilies/frown.gif" border="0" alt="" title="Frown" class="inlineimg" />
