replyNo, it won't. The power drain of merely refreshing DRAM is negligible, it's no higher than the drain you'd see in S3 standby over the same time period.
Given the DRAM refresh is part of S3 standby, I'm afraid this is circular reasoning.
replyI suspect this is one of those "it depends" situations; does the 128gb vs 64gb sku have more chips or denser chips? If "more chips" probably it'll draw a tiny bit more power than the smaller version. If the "denser" chips, it may be "more power draw" but such a tiny difference that it's immaterial.
replySimilarly, having more cache may mean less SSD activity, which may mean less energy draw overall.
If I had a chip to put on the roulette table of this "what if" I'd put it on the "it won't make a difference in the real world in any meaningful way" square.
I thought my Z620 with 128GB of RAM was excessive! Actually, HP says they support up to 192GB of RAM, but for whatever reason the machine won't POST with more than 128GB (4Rx4) in it. Flawed motherboard?
