To find out what memory you have onboard and also where it is, here is a neat command<\/p>\n
\r\nlshw -class memory\r\n<\/pre>\nHere is my output<\/p>\n
\r\n *-firmware \r\n description: BIOS\r\n vendor: Acer\r\n physical id: 0\r\n version: V2.04 (01\/15\/07)\r\n size: 103KiB\r\n capabilities: isa pci pcmcia pnp apm upgrade shadowing escd cdboot acpi usb agp biosbootspecification\r\n *-cache:0\r\n description: L1 cache\r\n physical id: 5\r\n slot: L1 Cache\r\n size: 16KiB\r\n capacity: 16KiB\r\n capabilities: asynchronous internal write-back\r\n *-cache:1\r\n description: L2 cache\r\n physical id: 6\r\n slot: L2 Cache\r\n size: 4MiB\r\n capabilities: burst external write-back\r\n *-memory\r\n description: System Memory\r\n physical id: 12\r\n slot: System board or motherboard\r\n size: 2GiB\r\n *-bank:0\r\n description: SODIMM Synchronous\r\n physical id: 0\r\n slot: M1\r\n size: 1GiB\r\n width: 32 bits\r\n *-bank:1\r\n description: SODIMM Synchronous\r\n physical id: 1\r\n slot: M2\r\n size: 1GiB\r\n width: 32 bits\r\n\r\n<\/pre>\nI basically have 2GiB of memory and also L1 cache (on die cache on the cpu) of 16KiB and 4MiB L2 Cache.<\/p>\n
Here is a wiki page that details what L1 and L2 cache are CPU cache<\/a>, basically L1 means on CPU die, and L2 means slightly further away from the L1 cache. If there is a memory call L1 is the first hit, then L2 and then the memory and then swap space (harddrive), the lower down the line means slower result time.<\/p>\n","protected":false},"excerpt":{"rendered":"To find out what memory you have onboard and also where it is, here is a neat command lshw -class memory Here is my output *-firmware description: BIOS vendor: Acer physical id: 0 version: V2.04 (01\/15\/07) size: 103KiB capabilities: isa pci pcmcia pnp apm upgrade shadowing escd cdboot acpi usb agp biosbootspecification *-cache:0 description: L1 … Continue reading Linux – memory and where is it<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[37],"tags":[40,398],"class_list":["post-381","post","type-post","status-publish","format-standard","hentry","category-linux_install_configure","tag-bash","tag-linux"],"_links":{"self":[{"href":"https:\/\/www.codingfriends.com\/index.php\/wp-json\/wp\/v2\/posts\/381","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.codingfriends.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.codingfriends.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.codingfriends.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.codingfriends.com\/index.php\/wp-json\/wp\/v2\/comments?post=381"}],"version-history":[{"count":5,"href":"https:\/\/www.codingfriends.com\/index.php\/wp-json\/wp\/v2\/posts\/381\/revisions"}],"predecessor-version":[{"id":430,"href":"https:\/\/www.codingfriends.com\/index.php\/wp-json\/wp\/v2\/posts\/381\/revisions\/430"}],"wp:attachment":[{"href":"https:\/\/www.codingfriends.com\/index.php\/wp-json\/wp\/v2\/media?parent=381"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.codingfriends.com\/index.php\/wp-json\/wp\/v2\/categories?post=381"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.codingfriends.com\/index.php\/wp-json\/wp\/v2\/tags?post=381"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
