DDR2 REF Voltage????

[DaMulta]

How do I add Ref voltage to normal DDR voltage?

I can go +2.0 on the Ref.

But only up to 2.3 on the normal DDR2 Voltage.

2.3V is the maximum DDR2 can go.

But if you want more you should buy a DDR Maximizer

I just want to know what DDR2 REF Voltage is.....

I'd like to know also, that's a term I'm not familiar with. I looked into some M/B's that use DDR2 REF Voltage settings along with regular DDR2 Voltage settings and it appears to be another way to fine tune/adjust/increase the voltage being applied to the memory. But I have yet to find a decent explanation of it. Probably would be useful for extreme overclocking of memory, I am intrigued by this now, I will keep diggin for info on it!

I don't know if this helps but here is the link

It's a PDF

1.8 is ref.


Besides I don't trust a document that misspells compromising.

so REF=Reference or stock setting then? That would make sense, so then Dam's 8500 ref or recommended stock voltage is 2.0v then? Interesting, good to know. But what about DDR Voltage REF settings on M/B's, a couple had +2%, 0%, -2%, or +.3mv, 0mv, -3mv, something along those lines...

The problem is when DDR2 hit the streets it was supposed to be the final answer to high power hot memory. But that didn't happen, just like with DDR, more voltage means more speed or lower latencies. So some brands require 2.0 or 2.2 for their rated speed and timings. Thus making then no better than a 1.8 set that runs looser timings but can run faster at higher voltage.



Long story short.

1.8V @ 5.5.5.15 400Mhz
2.0v @ 5.5.5.12 400Mhz

Both should do 420 or 430 at 2.0 or 2.1v and @ 5.5.5.12 timings most likely. The rest is just bullshit marketing games.

So far as the mother board values it is just showing compatibility for SPD modules to boot to stocks settings IE 5.5.5.12 @ 2.0 400Mhz.

That's what my board has.

Sounds almost like it's an additional boost to vDIMM.

So on one has used this?
