Model of the motherboard:GA-EP35C-DS3R
Model of the memory: G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM
Model of the CPU:Q6600 G0
What is the problem? cant overclock CPU
I've had this system for 3 years.
I used to have 4GB (2x2GB) of CORSAIR DOMINATOR 240-Pin DDR2 1066 (PC2 8500) in my GA-EP35C-DS3R / Q6600.
I could overclock that, completely stable, to 3.6GHz.
I needed to go to 8GB, so I added 2 more of the CORSAIR DOMINATOR. I could still overclock, but only to 3.4Ghz, and only with +.5 Mem Overvolt and +.3 northbridge.
And I got occasional blue screens. Mem test iso also reported errors.
So, I bought G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 1600 (PC3 12800) hoping I'ld get complete stability.
But now I cant overclock at all. If I try to go over 2.4, the system multi-reboots and goes back to 2.4.
I've tried more voltage (CPU, memory, northbridge), and dropping DRAM timing down to 2.0 (as well as trying it at auto) and setting timing to 10,10,10,28
But nothing is working.
Can I not overclock this system any more?
Did I buy the wrong memory? Do I need DDR3 1066 or 1333 instead of 16600?
Thanks for any thoughts....
