    I agree with Austinian. But I'd also add that you need to be a knowledgeable buyer if you go the mass-market route. There is a lot of junk out there as well as well-configured machines, and you ...
  • This advice has absolutely nothing to do with the load.
  • Matched ratio. That is the usual definition of the word to an EE (I'm one also). The ratio needs to be precise, but the absolute values are not critical.
  • All RAM identical? As in RAM clock speed? Size? Supply voltage? All mobos having the same number of slots? The same features? You're kidding, right? Maybe not.
  • Actually, the absolute values are not critical, but they do need to be matched.
  • This is a myth, earnestly held by the hobbyists. PSU: Many enterprise boxes use 80-Plus Gold PSUs. Easy to find one configured that way. RAM: A commodity, identical in all computers. Never fails if ...
  • A voltage-divider or multiplier circuit requires two resistors. I did not want to imply that all cameras use a mix of digital and analog gain settings, just that it is a lot simpler to do a series ...
  • Sure there is. Each gain step requires a matched pair of resistors. Much easier and cheaper to have a few x2 stages that can be used in various combinations to generate x2, x4, x8, x16 etc (the ...
  • Price is actually a good indicator, as the enterprise-grade components are more expensive; you get what you pay for. An enterprise-grade box is $200-$300 more than a similarly-spec'd consumer model. ...
  • My suggestions: i7 processor (no particular type, differences in performance no longer affect your use) 16 GB RAM (might go to 24 GB if you are doing very big files) SSD main drive (500 GB or more; ...
  • What is it with guys who worry that theirs is smaller than the other guy's? ;-) The main reasons I use an enthusiast camera rather than just a cell-phone: - low-light performance and control of ...

    I agree with you. Just pointing out that RAM access time dominates processor throughput (much more than processor clock rate), even with big processor caches -- there's just too much concurrent ...

    Assume cache access time is .2 nsec and DRAM access time is 100 nsec. 90 cache hits + 10 memory hits = 18 nsec + 1000 nsec = 1018 nsec. 100 cache hits = 20 nsec. 50X improvement!
  • Good idea, Populate all your memory slots with identical memory sticks.  Get the rating that is suggested for your motherboard. It's simple.
  • Replied in Praise for B&H?
    Really? I took advantage of the same Panasonic $300 offer at Hunt's in Boston, where at least the salespeople on the floor knew about it. Nothing against B&H, just saying....
  • Repeating what was said in the comments just above - why?
  • Also a dirt mark on the lens or sensor in the top right.

    You're getting really boring Robert... You must be a hit at parties...

    Actually, I'm from Normandy. We took you over and improved your language back in 1066. ;-)
