Does Vishera/Bulldozer have that voltage limit?

post #1 of 3
Thread Starter 
Hey, anyone know if Vishera/Bulldozer have that voltage limit on the memory or else it might damage the IMC like on the Intel i7s?

It's all the same. There is no limit. From a CPU manufacturer stand point, they have to say use standard 1.50V memory. Reason being a lot of people can screw up/burn the CPU by applying random high voltages to the CPU memory controller. Consequently, that leads to unnecessary high RMA due to amateur overclockers.

Fact is, there's plenty of room for overclocking, and 1.65V for DRAM is perfectly fine for AMD and Intel. Extreme overclockers run 1.70+ all the time, and they can easily do so because they understand how to adjust all other voltages/settings accordingly.

All DDR3 memory is basically universal. There isn't a memory kit on the market that is DANGEROUS for any CPU. Memory is standardized, so even the most extreme memory can be used with a cheap CPU. DRAM is not like a GPU that is pre-overclocked from factory.

If you are looking to buy RAM, Bulldozer and Vishera can support DDR3-1866 just fine. DDR3-2133 and DDR3-2400 is possible as well, depending on what capacity you need and how good you are with overclocking.

Cheers !

Phenom, Bulldozer, Vishera have the same limits..... Unlike Intel chips where running RAM over 1.65V runs the risk of burning out the CPU's IMC, this does not come into account on AMD CPU's

You can run 1.7-1.8-1.9V and beyond without running the risk of damageing the IMC on a AMD CPU
