RAM needs to be underclocked? [SOLVED]

[shoutingsteve]

Alrighty, so I've searched around the forum and found a bunch of helpful information, but nothing that actually answered my question.

I recently upgraded my videocard and during the benchmarking process with that I discovered that even though I have 1333 memory, it is running at 1066.  So I restart my rig and enter the BIOS to change it to 1333 (factory clock.. so says the sticker afixed onto  the modules).  I press the key to commit the changes and reboot.

then...

cycle. "hmm... that's odd"

cycle. <internal panic>

cycle. "Son of a ---"

Boot. "thank god!"

 

but the ram is still at 1066.  Any idea why the rig won't boot at 1333?  All four modules are identical and bought at the same time.  BIOS has dual channel mode enabled.  I have it at stock voltage, should I bump that up a bit? or is that where I should leave it?

What voltage is 'stock voltage'?

Also, don't underclock the RAM, it'll just make it a lower frequency.

It's at 1.5 volts.

And, believe me, I don't want to underclock it.  The system won't start up unless it is underclocked.

You can't just change the frequency and expect it to work without also increasing the voltage and/or changing the timings. This is why XMP exists. Turn it on and you should be good to go.

Ok.  cool.  So, do I just need to turn on XMP and it will adjust the timings and voltage for me or do I need to do all three things manually?  There is no danger of me turing on XMP and also upping the voltage, and then the XMP also upping it causing them to burn up, is there?

Here how i fixed it (thanks badreg):

Entered BIOS and although XMP was not a selectable option for me (the drop down menu as shown in my user manual simply wasn't there) I was able to relax the timings to the cas latency as printed on my ram sticks (from asus auto detect putting them at 8-8-8-20 to patriot's factory specs of 9-9-9-24.) when I changed the frequency from 1066 to 1333.

but I also had to increase the voltage from 1.5 to 1.6 (1.5 being the factory and 1.6 just being raised because when I only relaxed the cas latency and bumped up the frequency it entered windows but then failed immediately)

 

Thanks for your help, guys and gals.

Have you run any memory tests?  To make certain you don't need a little more DRAM voltage.
