Corsair XMS 2x2Gb PC2/6400

post #1 of 4
Thread Starter 
So I ended up making a hasty purchase yesterday to get my rig up and running. I bought the Corsair XMS 2x2Gb PC2/6400 800MHz 5-5-5-18 2T 1.8V modules. I'm new to running 2Gb modules and understand that it's a different game from running 1Gb sticks.

First- Any one perhaps know which ICs are on these modules? TWIN2X2048-6400C5DHX

Corsair is not very clear about what the maximum voltage is, stock is 1.8V, but how high can I take it?

Finally what kind of timings would be 1)reasonable 2)killer? 4-4-4-12? Maybe lower at increased voltages?

What am I the only one who has these sticks?

Well, I finally found Corsairs max reccomended voltage is 2.1V- not much "safe" headroom. I've been able to get stable 4-4-4-12 @ 1.96V BIOS/2.06V DMM tested. I think that's all I'll be able to squeeze out of them for timings.

you edited your qoute.....about the Elpidas doing good at low voltage.

I think that running 4-4-4-12 @800MHz/~2.0V is average. I wonder if it will run 450x8 at those timings/voltages.

Elpida lists max VDIMM as 1.9V, Absolute Max Voltage as 2.3V
Corsair lists Max reccomended VDIMM is 2.1V

When I get my Ballistix back, I may just see how much VDIMM these Elpida ICs can take, since Corsair's lifetime warranty says nothing about OV/OC invalidating it.
