  2. "voice memo" bandwidth/bit rate/sampling

    OK, I'm getting confused info about this.

    What is the sampling rate (bits per sec/kHz) of "Voice Memo" in iOS12? I understand there are two selectable audio qualities - one "uncompressed", and the...

    I don't think anyone is talking about using SSD architecture in place of RAM. What I'm talking about is using NAND flash non-volatile memory architecture (which is the basis for SSDs) as RAM. It is...

    Sure, an R&D program to make really zippy SSDs might cost a lot. But you don't know if it would be expensive, or super expensive, or super super expensive. You also don't know if once the R&D program...

    I think that's not the reason. Price per GB is lower in SSD than DDR RAM. The reasons were comparative speed of RAM and likely degradation of SSDs.

    Which is why I was confused about your response. Kinda obvious that if market forces drive them to do it, industry will do it.

    Much appreciated.

    Well, I was never criticizing anyone for not doing it. Pretty obviously if it were a smart thing to do, hardware manufacturers would be all over it. My question was WHY it isn't done. Saying it isn't...

    Hard thinking provokes well thought responses. There is NO QUESTION (and never was) that an SSD would be a big improvement. That wasn't what my question was about. I was just wondering whether the...

    Thank you. I think the critical info is that SSD memory is generally slower than RAM and that it has limited lifecycles. No question that machines these days are designed to have RAM that is directly...

    Not sure what you mean by saying that they are two different things. They are both solid state memory. Granted, they're used differently by the OS, but why can't the OS just carve off an 8GB chunk of...
  11. RAM versus SSD on MacBookAir

    I just upgraded my RAM on a MBP, from 4GB to 8GB. Works MUCH better now. But I was wondering about MacBookAirs (as in 7,2) with SSD. I understand the RAM is currently sold at 8GB, and hardwired in....

    Well, the hardware was a 1333MHz RAM card, not a 1067 MHz RAM card. So that hardware wasn't telling the machine what it's speed was. If I put on a small shirt, even though my size is large, you don't...

    So I did a RAM integrity test on the iMac with some 1333GHz RAM installed (instead of just 1067MHz RAM) using MemTest86. Passed with flying colors. Boy, MemTest sure works it hard. Can almost see the...

    OK, just reporting back. Using two 2GB 1333 GHz DDR3 RAM cards (from a MacBook Pro 8,1) in an iMac 10,1 (for which 1067MHz DDR3 cards are native) DOES work. Appears to be just fine. I have yet to run...

    Yes, while I can get a rebate on replaced modules, that rebate is insultingly low. Just a few bucks. They probably turn them around and sell them at an enormous profit. I'll put in my order for new...

    No one is talking about using DDR3 memory on a system that doesn't support DDR3. In fact, now that I research more closely, even within DDR3 devices, there can be large differences in refresh timing...

    That's helpful. Those links speak directly to my question. So people say yes, it can work. Though at least one says it didn't. A little odd that people in the apple.com discussion are suggesting that...

    Thank you. But what I read is that refresh timing is a matter of device generation, as in DDR number. These are all DDR3 chips. That being the case, the matching should be assured. You'd think there...

    memory compatibility

    Probably a silly question, but how intercompatable are memory cards in Macs?

    For example, I have a 2011 MacBookPro 8,1 that I'm going to do a memory upgrade on. So I'll be pulling out a couple of...

    Nope. This was just a plain old partition made with the OS partition manager in Disk Utility.

    Oh, well, that was easy. I just selected the whole drive in Disk Utility, and pressed "Erase". Whammo. No more partitions. But why doesn't the "-" in the partition manager do it? Screwy.

    That's precisely what I did. El Cap, MBP, external drive. Somehow, I didn't manage to have RW permission on the partitions. So I fixed that, and still no joy.

    can't unpartition

    So I have a drive divided into two partitions. I want to remove one partition, and make the drive a one-partition drive. Should be easy, right? I go to Disk Utility, select the partition, and expect...
