Hello everyone my name is Jeff i know i posted about this before but i closed it out. My setup consists of a i7 950, rampage formula III mobo, and mushkin redline ridgeback 3x2 memory model # 998826 but with red heatsinks. My problem is that my memory will not pass a memtest or stress test in triple channel. It does affect my gaming at times it will restart randomly etc etc. In dual channel with only 4 gigs it runs everything perfectly. Passes memtest linx everything. i have re=seated the cpu, loosened and tightened my cooler, all to no avail. I even rma'ed my motherboard ram and processor. they all came back with the same issue. it fails the tests in xmp, my own settings and stock 1066 settings. Whenever i run memtest it always says the failures are at 1909.8mb i dont know if this info helps anyone Also my ram is disappearing as well. I have six gigs installed at all times and cpu-z always shows six but my bios and windows show 4. I'm hitting my head against the wall, please anyone have some insight, sorry about the double post. Any help is very much appreciated
Sounds to me like a setting on the ram thats just out of reach. Try upping the ram voltage a notch. If that doesn't work, test each stick by itself to see if you (still) have a bad one. Finally, relax the timings one notch. Remember to not exceed 1.65V on the ram.
on the xmp settings it sets the voltage on the ram automatically to 1.65 volts. i ran memtest at 7-9-7-28 and 8-9-8-28 and neither one passed. at 7-9-7-28 it passed the first loop then failed on the second loop. same address of 1909.8mb, i tested all the memory in single channel on all the dimms they all passed
