Memory Voltage and Sandy Bridge

post #1 of 15
Thread Starter 
Hi there,

I'm in the process of upgrading my PC from AM3 to SB. I would like to use my old memory kit (Kingston HyperX Blu 2 x 2GB GB DDR3 1600MHz) on the SB platform as well. The RAM voltage is specified as 1.65v. Now i know SB requires 1.5V. My ram is currently working at 1333mhz and CPU-Z shows a voltage of 1.50v for these operating frequencies. Can anyone shed a bit a light on this ? Do i need new ram ?

Thanks

No you do not need new RAM. The sandy Bridge mother boards run RAM at 1.5v default. You kit will run at 1.5v as you have shown. If you have to bump the voltage it can be done in the BIOS. Some of the SB motherboards are picky with RAM though. If you have boot troubles you may need to bump the voltage.

You're memory runs on 1.5V @1333Mhz and 1.65V @1600Mhz. (not sure.)
Look again in the table of CPU-z

That would mean (if you want to be safe) you should run it @1333Mhz.

Thanks ! After researching a bit i was able to confirm that my ram runs 1.5v @ 1333Mhz, which is the default clock both on AM3 and SB. So it should work perfectly with the SB as well hopefully.

On a short term it can yes. It's questionable on the long term though from what i've read.

dude look at this:
http://www.newegg.com/Product/Produc...-562-_-Product
http://www.newegg.com/Product/Produc...-450-_-Product
http://www.newegg.com/Product/Produc...-431-_-Product

ARE ALL DESIGNED FOR P67 MOTHERBOARDS WITH A FACTORY SETTING OF 1.65V why in the world would manufacturers use a un-safe voltage as it's stock setting?

people are just paranoid because the memory controller is on the chip itself

Sandybridge maximum safe voltages :

Core Voltage - Not recommended too exceed 1.38v, doing so could kill the CPU, we therefor recommend a range of 1.325-1.350v if overclocking.
Memory Voltage - Intel recommend 1.50v plus/minus 5% which means upto 1.58v is the safe recommended limit.
BCLK Base Clock - This is strictly a NO, anyone using base clock overclocking could/will cause damange to CPU/Mainboard.
PLL Voltage - Do not exceed 1.9v!!

I would take those "guidelines" with a grain of salt. Many members are pushing their RAM kits at 1.65v and pushing CPU's well over 1.4v 24/7.

Unless you don't plan on upgrading cpu or mobo for 2+ years, I'd recommend follow those guidelines from Intel. And this is OCN, many people will upgrade before the chip dies (mostly around 1 year or 2). I wouldn't go over the specs. Your chip will degrade if too much voltage is put into it so...Dont Do It

edit: I just recall some reviews for the ram on Sandy bridge systems and most memories clocked over 1600mhz yields little to no better performance even in benchmarks.
