Try loosening the timings on the ram so that you can clock it higher. That should get it a bit higher for ya.

Ok, so give your RAM to the original poster and the problem is solved.
Anyways, is your cpu stable above 400 with other RAM? Check just incase. It looks like your RAM should run those clocks at DDR2 1066 with 2.0V to 2.1V so it should work. Maybe try re-seating the RAM ro putting it in different dual-channel slots and testing again.

First I will try reseating like you suggested. I also have a pair of GSkill DDR2 800 (PC2 6400) that I will be trying when I get home tonight. I don't know if both of the slots on my board are dual channel, wouldn't that cause other performance issues later on if they are not both dual channel?

I know a bit about overclocking and this motherboard so I have a relatively good understanding of what the different voltages do and what they "should" be. My bios settings are as follows:

I'll also try to test each stick individually tonight. If I have a bad set, oh well. I'll just RMA them to GSkill and hope to get a set that can do 500. In my opinion though, if the ram can't run at it's rated speed with a 1:1 ratio wouldn't that ram be considered bad? To be honest I've never messe with the ratios, I've always ran 1:1 on all the systems I've built.

Your SB shouldn't really be involved with MemTest stability but your NB could possibly be effecting it. If your NB is at Auto try finding the normal voltage for it and manually set that voltage. I know on my mobo that it can undervolt the RAM on auto so there is a chance that other mobos could undervolt other things I guess. |

If all else fails try testing with each individual stick and each slot. BTW, the best testing for an error is to remove as many posibilities as you can so you might want to check unlinked or different ratios other than 1:1 as well. |

No, no, no.
Your RAM is not rated for 500 MHz FSB; it's rated for 500 MHz.
Two very different things.
You have a quad core.
Getting a quad core stable at higher FSBs can be a challenge, & while no one else in this thread seems to understand this, the entire reason you cannot get Memtest stable is because your FSB/NB/system isn't even close to stable right now, & it has absolutely nothing to do with the RAM.
You'll need to increase VTT/MCH somewhat, & possibly manually adjust your corresponding GTLs for those as well, to get things stable over 400 MHz.
And for testing the RAM, run the FSB at more realistic speed, & use a non 1:1 ratio to achieve DDR2-1000.
So as an example: 333 FSB w/ 3.0 ratio = DDR2-1000.

Max 1:1 is whatever you can get your board stable at.
Your RAM isn't going to be limiting you; your board will.
I'd suggest heading over to the mobo section & reading thru the UD3P thread to get an idea of what settings you need to work on.

What I'd like to be able to do is run it at 500 in a 1:1 ratio; to me that's truly running at 500mhz. Doesn't the fsb have to slow down and wait when the ram is OC'd via ratios? I've always thought that max 1:1 is best and then use ratios to push the ram that little extra bit. I'm basically trying to find what my max 1:1 setting would be. |
