Hi.
I have 2x4GB DDR3-1333 G.skill and an Intel i5-760 on a MSI P55-GD65.
With everything default (bclock 133) the mobo sets the ram to 1333 MHz 9-9-9-24-1T 1.5v and it runs perfectly.
So, this isn't a problem with the ram not doing what it's supposed to.
I have the system overclocked with bclock 182 MHz and cpu 4 GHz with VTT at 1.154v.
When I was finding those settings I had the ram set to a 2:3 ratio from the 2:5 default, and the ram was fine throughout.
However, my goal for the ram was ~1456 MHz (182x8), since my mobo only has 2:3, 2:4, and 2:5 ratios available.
I set the ratio to 2:4, bclock to 150 MHz, and timings 9-9-9-24-2T 1.645v.
I was able to bring the bclock up to 166 MHz stably (DDR3-1328).
Trying 170 MHz (DDR3-1360) the system will fail any of Memtest86+/Intel Burn Test/Prime95 blend.
I kept raising VTT from 1.154v until I hit 1.236v, and each time it failed.
I curently have the ram stable at 7-8-7-20-2T 1.550v with a 2:3 ratio (DDR3-1092).
I would rather have the ram running faster with looser timings, so what I was wondering was if this was normal for this ram.
Thanks for any help.
