Does VCCIO need to be within 0.5v of DRAM on SB Platforms?

post #1 of 6
Thread Starter 
Hay all...

As the title says. Does VCCIO need to be within 0.5v of DRAM voltage on the Sandy Bridge Platform?

So. As an example:

DRAM: 1.65v

Does VCCIO need to be 1.15v to be within that 0.5v value.

That's what I've heard. So I guess, yes. Or it is recommended

The problem I have is I've tried to set it to 1.15v and it just causes instability...

Anyone got any ideas?

Nope it doesn't. It only applies to older gen sockets.

Sandy Bridge does not require there to be a maximum of 0.5v between the VDIMM value and the VCCIO and VCCSA values when 1.65v voltage modules are used.
