Hi,
Has anyone had a Memory DIMM just fail -with no errors?
My sytem posts, but the BIOS won't recognize one of my DIMM's when I'm overclocking.
I used these settings: http://www.overclock.net/intel-mothe...-thread-5.html posted by Xmisery (Thanks!) with HT on.
I'm on the latest BIOS 703, and have moved the DIMMS on my MB, so I believe its the DIMM - not the MB.
When I reset the BIOS to all Default, all 3 sticks are recognized and I get 6GB, but when I start to OC at some point my memory simply doesn't all get recognized.
The memory I'm using is from NewEgg: G.SKILL PI Series 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7T-6GBPI - Retail
Item #: N82E16820231335

Any recommendations?
Thanks! Ziggard

I don't think I'm overclocking the RAM - as its 1600 - and I'm at 1531 - but I'm no expert. I just used the settings I referenced from a previous thread. All my settings are below, and I'd like to change the "vRAM", but I don't have that option.

Based on my settings below, what should I change?
Thanks!

It seems to be a common issue with Asus X58 boards. So it is in fact the board, not the memory. You need to change some settings.

the vRAM is DRAM Bus Voltage in that BIOS, but you're at 1.64 with looser timings and lower frequency than the stock RAM spec, so it's not that

try increasing the QPI/DRAM core voltage to 1.3v and see if you still get errors; if you don't that's your solution, and you can work on lowering that voltage

you may need to increase CPU PLL to 1.88v, and since you're using CPU clock skew, change the IOH clock skew to the same, I think that's recommended

also, not sure if it makes a difference, but put the QPI Link Data Rate to the lowest value from Auto

play with that and see what you get

Thanks for the great tips. I did make many changes based on the great recommendations, but at last this morning, I'm again back down to 4GB of memory.

Would it help if I had my CPU down to 3.6Ghz? Any other recommendations?

Thanks for your help!
