Are 4GB sticks just as stable as 2GB sticks?

Lets say you want a very solid memory (either for overclocking, mission critical apps, etc). How do 2GB vs 4GB sticks compare of the same manufacturer/series/etc?

You get a server board and ecc ram. 🙂

ehh...there is no difference besides the amount of memory...

Yeah, for "mission critical" applications you don't overclock and you use ECC memory.

hp sells 4GB SLC SDHC and 2GB USB SLC SDHC for vmware. its rebadged but SLC goes along way further than cheap mlc.

....Um what?

I don't see any difference in speed between 2GB sticks and 4 GB sticks.

I think the OP is curious if 4GB would be less stable in overclocking/overall system stability compared to a 2GB stick. If the motherboard was subpar or the power circuitry was old and degraded, smaller sticks of ram might be more stable. :hmm:

Technically a larger stick has a higher odds of a bit flip just because it has more locations. The odds are still very low once the stick is proven. I think VMWare did a study on it since they typically have systems with 48 - 768 gig of ram in them.

4GB should fail twice as often as 2GB (I don't understand the complex math behind this, including how to count to 10), but I would be much more concerned over the chips themselves since most modules now, including from the largest manufacturers, are made from rejected chips, a common sign being their higher voltage requirements. That isn't to say 1.5V DDR3 or 1.8V DDR2 modules are usually made with first quality chips.
