RAM timings.

[Smithy0115]

There are two different RAM kits I can but and they are identical apart from timings, voltage and MHz.

Could I use RAM with 9-9-9-27 timings on a Sandy Bridge P67 motherboard, the RAM is also 1.65V and 1600MHz?

The speed and the timings don't matter.

For Sandybridge you want RAM which runs at around 1.5V.

These are the most popular choice:

Corsair XMS3 4GB (2x2GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit £39.98

Corsair XMS3 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit £79.99

I'm looking at some 8GB XMS3 at 1.65V, would this be alright?

EDIT - this: 8GB (2x4GB) Corsair XMS3 DDR3 PC3-12800 (1600), Non-ECC Unbuffered, CAS 9-9-9-27, 1.65V

What's the manufacturer's code of the RAM you're looking at?

CMX8GX3M2A1600C9

CMX8GX3M2A1600C9

Which is the same code as the kit I linked to.

It should be 9-9-9-24, 1600MHz.

Rated as 1.65V but many have used it in Sandybridge builds at around 1.5V.

It's listed on the site as 9-9-9-27, so if i use it will I have to change bios settings to make it run at 1.5V?

When you install it in a Sandybridge board it will default to 1333MHz.

You'll have to manually set the speed, timings (possibly) and voltage in the BIOS.

You want the voltage as low as possible without causing instability.

Start at around 1.5V and increase it in small amounts if you need to.

I run RAM in my 1st gen i5 rig @ 1.5v (rated 1.65v) so 1.5v in a SB build should be fine.
