That seems important, right? How can they be different for the same computer? (I'm not really concerned about price unless they could sell it cheaper by making it at the wrong, lower voltage. ) Do I need to look up what the computer puts out? Would one of these be overclocked if the computer puts out 1.5v and the other underclocked if the computer puts out 1.35? I already have 2 sticks, Do I want to get the same voltage that they use, whatever that is? ------ Other differences are Crucial says PC3-12800 but Kingston doesn't include that. Kingston says X8, 2R, 4Gbit but Crucial doesn't include any of that. Does any of that matter? ------ FTR, I only looked at Newegg because Crucial was out of stock. NewEgg says "Ships from China. Newegg Most customers receive within 10-32 days." Hmm. At https://www.newegg.com/crucial-16gb-...82E16820156047 it says sold and shipped by Ram-Store and when you click on 12 New from $88.46 , it goes to the bottom of the page where they have 12 vendors selling the same thing. Just like Amazon does it. I only looked at the first 5 but one is in Hong Kong and "Most customers receive within 4-17 days.". One is in the US and "Most customers receive within 7-9 days", all except Hong Kong for the same price!! (For Hong Kong and the next 7 the price gets higher.) But this doesn't matter until I understand the voltage question. Hi Micky, Call Kingston tech support and describe the issue to them: 877-546-4786 714-435-2600 Kingston's customer service is something to behold. Because of it. I only sell their memory, unless they don't carry what I need. They really, really back their stuff up. -T Thanks. I almost did this but then saw that I had Samsung in there now. So unless someone tells me I shouldn't, matching the dimms that are there now is the right thing to do? SAMSUNG M378B1G73DB0-CK0 My experience is that you should match them Good. That settles it. You know there are more nuances than that. Well, I thought it did. If Dell sells a 6GB machine, you know right away it shipped with a 4GB and a 2GB module, and it left the factory in an unmatched state. The machines are obviously flexible to some degree, as these non-power-of-two machines are quite common at retail. I try not to send people on excessively constrained missions, if I can help it. FLEX memory capability has probably been around now for ten years, and lots of machines can accept, say, 512MB,1GB,2GB,4GB in the four slots and still work. Is it "optimal" ? Of course not. But for the average user seeking an easy upgrade with garbage in the desk drawer, it'll work. And the Intel caching structure makes any reduction in memory speed, almost invisible to these choices. (older AMD, less so) It's better for the user, if they have a "retail" motherboard in a home-built machine, as those have extensive controls (even if I don't know what to do with all the settings!). It's the Dell and HP machines, you have to use your intuition as to what aspects of memory choices will antagonize the BIOS, or not. Nuances beyond my ken, but I can tell you didn't say no. "Strict matching" is a good rule for say, S939. Aha, https://en.wikipedia.org/wiki/Socket_939 Very interesting. Paul Hi Micky, All the machines I build come with way more memory than the customer will ever use. I just get sticks with the same part number from the bin next to each other and have never had a problem. I don't bother buying "matched" sets. I have had memory upgrades where I told the the customer that is was not worth the problems to try to get mismatches to work. They have always just let me remove the old ones and install new ones. Memory prices have really come down. My main office machine is Fedora 33 running 16 GB of ECC memory. I have 11 virtual machines. I get away with running two at a time with not issues. I have had five running before and it starts to slow a bit, but I don't run out of memory. -T |

Several places that google found were out of stock, but as is not uncommon, Amazon had it, although its sold and shipped by Dataram, a company that's 54 years old and made ram themselves, and I think they still do. And it's even in New Jersey so maybe I'll get it a day or two earlier since I'm in Baltimore. (though it says 14 days. That's okay.) Things usually come when Amazon says they will or 1-3 days earlier, but this time the webpage said 11-14 days. But...

I did get it today, with the regular mail. 2 days instead of 11-14. I'm glad I didnt' pay extra for faster shipping. Amazon is indeed delivering quickly usually and on Sunday someetimes, but just to be clear, this was sold and mailed by Dataram. Though not from Princeton but from Chalfont, Pa which is about 20 miles north of the Philly, even closer to Balt than Princeton. |
