I have just tested my Crucial Ballistix Tracers DDR2-1066 with memtest and got back 72 errors. Whats up with this? I have not been having any blue screens or problems but I also have not tried to OC yet with this new MB. This memory was in my ASUS P5K-Deluxe OC'ed to 3.6GHz but the memory was set at 800 and not 1066, so I would have a 1:1 with FSB.

So, I guess now I need to check each stick individually? Then when I find the bad stick(s), do I contact Crucial for an RMA or what?

Need advice plz.

The memory is now in my Rampage Formula MB. See my sig below for system info.

After you find the bad memory stick you can rma it. I just got the same mobo today, it maybe a bios issue but i doubt it.

u dont have a sig below.??? same with me, my sig doesnt show up when i enable it. if its running in spec, whatever that is and it fails memtest, then RMA. at first run ur proc at stock and ur mem at rated voltages and timings then run it again.

try 1 stick at a time too, after that

The quality of much RAM sold as faster than DDR2-800 these days is sadly lacking.

I am running my ram at manufactures spec's. DDR2-1066 5-5-5-15 @2.2v
The voltage has never been set higher or the timimgs tighter. So tonight I guess I will start testing each stick.

Here's my system;
CPU: QX6850 Quad Core Extreme 3.0GHz
Cooler: Zalman 9700 Ultra Blue LED
MB: ASUS Rampage Formula X48
Ram: 4GB Crucial Ballastic Tracer PC2-8500 DDR2 1066Mhz (4X1GB)
VGA: VisionTek HD 3870 512MB GDDR4 Overclocked Edition
HDD: (1) WD Raptor X 150GB (1) 300GB Seagate SATAII & (1) 500GB Seagate SATAII
Optical Drives:2 Plextor 810SA DVD-RW Combo
PSU: Thermaltake Toughpower 750W
Case: Antec 900
OS: Vista Ultimate 64bit SP1

Update,

Ran Memtest on 2 sticks and passed. Ran memtest on other 2 sticks and passed. Installed all 4 sticks of ram reset timings and voltage to spec's, then made two passes with memtest and passed. Don't know what swapping the memory around did but it passed memtest this time around.

Thanks for your input.
