Dead memory?

[fr0mat]

I recently purchased OCZ DDR2 PC2-6400 Reaper CL4 4GB Edition memory and installed it into my ASRock 775Dual-VSTA motherboard.

Although my motherboard only supports 667mHz, to my knowledge I could still utilize the 800mHz OCZ memory that I purchased above, and it worked for a while.

I purchased the memory on March 22nd and as of yesterday May 4th, the memory no longer works.

It was acting flaky as of late, where I would boot up my system and sometimes the keyboard wouldn't light up and none of the usb devices or displays would work.

So I threw in some old Corsair DDR 400mHz ram and it works fine.

To my knowledge using 800mHz memory in a system which supports up to 667mHz memory shouldn't fry the memory.

Could I have received faulty memory?

Thanks,

wait, what? You have a board that supports DDR and DDR2?

Anyway, if you can burn a memtest86+ CD or a Linux live CD, run the test. You shouldn't get any errors.

BTW, whats the RAM voltage?

Also, you're right, you don't damage the RAM, it just underclocks itself.

Yup, the ASRock 775Dual-VSTA supports DDR 400 / DDR2 667.

The specs say 2.1 volts.

Not sure if I can run the test you say because when I'm using the OCZ ram my display, keyboard, or usb devices won't work.

I've tested the faulty OCZ ram one stick at a time (2x2gb sticks). My devices will flash and my display will work but shortly after the boot up screens, I get some RGB pixels on a black screen and it never gets farther than that.

So I'm back to my old 1gig of Corsair PC3200.

Does it just sound like I got some faulty OCZ ram?
