Hi All,
First post so apologies if I get something wrong straight up
I am hoping someone can help me with my BIOS settings for this mobo/RAM combo. Some strange things are afoot which I just don't understand and it's driving me insane trying to fix it. Here is the short version of what is happening. Firstly the basics of the rig;
- ASUS P8Z68 Deluxe (Latest BIOS 3203)
- G.Skill 2x F3-12800CL9D-8GBXL kits (so 16GB all up)
- Intel Core i7-2600K 3.40GHz
- 2x OCZ Vertex II 120 GB SSD's in RAID 0 as the boot drive
- nVidia GTX480 GPU
I have had the G.Skill memory running without issue for around 6 months. To be honest, I couldn't tell you if they were in XMP, manual or auto as they just worked out of the box and I never checked. In any case, after returning from a month away from my machine, I switched it on and started receiving an array of various BSOD's and eventually could not even boot. To cut a very long story short, I eventually blew the hard drive away and rebuilt the machine, only to find that again, it would BSOD every time - normally after boot sequence. After this, I started pulling components one by one as a process of elimination until I got to the RAM. Low and behold, once I took out 2 sticks and reduced my RAM to 8GB, everything was fine.
Clearly there was a timing/voltage/BIOS problem. This is definitely the problem as I am running on 8GB now but after much experimentation, I CANNOT get the 16GB to work again! *VERY* frustrating as it's been fine for nearly a year.
I have tried the following set ups;
1. Default XMP - DDR3-1600MHz, CAS 9 9 9 24 (2), DRAM 1.5v, VCCIO 1.125v - FAILURE
2. AUTO - DDR3-1600MHz, CAS 9 9 9 24 (2), DRAM 1.50v, VCCIO 1.125v - FAILURE
3. AUTO - DDR3-1600MHz, CAS 9 9 9 24 (2), DRAM 1.55v, VCCIO 1.125v - FAILURE
4. AUTO - DDR3-1600MHz, CAS 9 9 9 24 (2), DRAM 1.55v, VCCIO 1.20v - FAILURE
I have read that running these at 1333MHz may help, but I'm no expert so need some solid advice. I should note that these sticks don't appear to be on the approved supplier list for ASUS either, so maybe that's an issue but if they worked for nearly a year then what's up with that?
I have read several posts on this topic but cannot find a definitive guide to setting BIOS for this combo. Nor can I explain why things have changed so significantly to make this memory stop working all of a sudden. Can anyone help? PLEASE? Huge appreciation for any suggestions or BIOS settings.
