Effects of running DDR2 at 2.2v daily?

[Stonedofmoo]

I've got some excellent Geil PC6400 memory that overclocks really well.

I currently have two choices. I can run it at DDR933 12-4-5-4 at 1.9v and it will happily complete memtest86 loops at this setting all day

OR I can run it at DDR933 12-4-4-4 at 2.2v and it will run memtest86 all day

The 12-4-4-4 doesn't really seem to have a significant impact on performance, only on the voltage requred to run it. Geil claims their memory is rated to 2.3v but realistically no one seems to runs theirs that high.

Should I run it at 2.2v and run the risk of stressing it day in and out, or settle for the slower 4-5-4 timing and run as low as 1.9v

Thoughts?

Because it's not. 2.2v is a lot for a DDR2 module, that will generate a lot of heat which will lead to instability without a fan or something to keep things in check.

I can run mine at 920, 4-4-4-12, at 2.1v no probs, if you are worried you could just take it down a bit and run them at 2.1v which is the rated voltage on the sticker, they do have a lifetime warranty anyway.

Same here, in fact thats exactly what mine runs up to at those timings at 2.1v

To go that little bit higher though requires that one notch more.

I'm going to get everest and superPI later and see if there actually is any real difference between 12-4-5-4 and 12-4-4-4
