Hi, I have built this pc back in November and once a while, the computer won't wake up properly from sleep mode. I remembered before that it can't even boot properly from hibernation mode. However, I think this problem might not be related since I realized that Windows 7 can't properly handle a HDD over 1TB, which it was fixed by installing some sort of a program giving by one of Microsoft's techs. Anyway, my motherboard has a RAM FAIL led and everytime, the pc fail to resume from sleep mode, the led lights up. I have just recently replace the ram under warrenty since I assumed it was a bad ram, but it didn't help. Well, the problem didn't occur again for about 2 weeks laters. I have tried changing the spec in bios to 7-8-7-20 with 1.66V but no help. I don't know, but in the DRAM timing control, there are 9 different timing. I only changed the first 4 to 7-8-7-20 so I have no idea if I should touch the other or not.
Asus P7P55D-E LX
Intel Core i5-650
Corsair XMS3 — 4GB Dual Channel DDR3 Memory Kit (CMX4GX3M2A1600C7)
EVGA Geforce GTS 450
Samsung 1TB HDD
Thermaltake TR2 500W
Windows 7 Professional 64-bit
Apparently, the cpu I have only support up to DDR3 1333. The one I have is design for 1600, but on Corsair site, it said this RAM's SPD speed is 1333 Mhz so I don't think this is the problem, and the bios is set to 1333.
both manual and self standby/hibernation (say like standby after idling for 30min) . And one thing, I don't know if it is the ram or the cpu, but the bios said I need to overclock the ram in order to set it to 1600 although it can support up to 2200. Right now, the only choice are 10366 and 1333 so, should I still try it?
edit: apprently, it is the bios that requires to set the profile to overclock in order to change to higher frequency. Even on the manual said "when using DIMMs with a freq higher than the cpu spec, use this to overclock the DRAM." So, I changed it to 1600, but some new stuff appear.
Cpu ratio setting: 20.0
It was in auto before so should I mess with these for now?
Edit: i don't know why but after changing the ram to 1600, for some reason, the cpu is overclocked to 3.86 Ghz even though the bios is saying 3.2 Ghz
