May 21, 2013 - If you accept the risks, here's how to create a 4+ GB/s RAM Disk on your Mac. Storage volumes created using a computer's memory (RAM) instead of. To run your Mac, however; if you use most or all of your RAM for a RAM. Upgrade your Mac Pro memory past Apple factory specs - up to 128.0GB in select models. Includes free DIY installation videos to make upgrading easy. Just a tip for those who are interested in using their USB flash drive as an extension to the virtual RAM of Microsoft Windows or to extend the virtual memory of the operating system. Using your USB flash drive to increase the amount of virtual RAM or virtual memory or pagefile to be specific is fine. But by doing this, you are also shortening the lifespan of your USB flash drive. Powerpoint 2016 for mac wont run slide show. Remember that USB flash drives have limited numbers of writes. In normal usage, it will take a long time for the writes to run out. But if the USB flash drive is used as RAM where millions of transfers are done each minute, it will definitely decrease the life of the flash drive. Many people don't seem to understand what virtual RAM is. Virtual RAM only kicks in when real RAM isn't enough. Then those programs that aren't currently active (say you have the window minimized) will get removed from main real RAM, and placed in the Virtual RAM. When this happens your computer will start 'swapping,' and can slow things down because putting things into the hard drive is considerably slow. Once the swap has occurred though things go back to being their normal seeming self. Until you reactivate one of the inactive programs (say you maximize a previously minimized window), in which case the swapping will start again, and cause a temporary hickup. The reason why putting the Virtual RAM (which is just an area of storage set aside for swapping things to) on flash medium may speed up the swapping cycle is because flash is a non-mechanical medium, and is (usually) much faster than a mechanical hard drive. The swapping 'hickup' moment will last a lot less longer than with a hard drive. Lots of people aren't seeing an increase in speed probably because they aren't actually using their real RAM to the max. If you want to experience the difference in speed, try running a RAM heavy program, something like Blender (with a big model loaded), or maybe even open up a lot of graphic heavy tabs in your browser. When your RAM usage is 80-90%, you'll start experiencing the grind of swapping. Test both with a hard drive virtual RAM, and on flash drive. Of course SSD will probably give you the best results. NOTE: Your flash drive will probably die a lot quicker if used in this way. U ca do all of this without usbflash. Just follow the procedure and just replace old page for virtual memory, which is already on your hdd. For example I don't remember the exact size, but I left it to 4gb. Which is more of enough because my physical ram is 2gb, so if all tasks are copied to the page, another 2gb will be free. On the other side, u can use this usbflash to create ReadyBoost. U'LL need at least 4gb drive if u using Windows 7. Format it under NTFS. In properties tap readyboost. Check third option and move slider completely to the right end. Then check second option and press apply again. Now all space will be filled with single file. Rename it as local disk and if doesn't have letter, give it one. Be sure u put this drive on the back side of the pc. This usbflash is assigned as Syaytem Drive and is already part of Windows. Do not remove it!!! RedyBoost will increase significantly performance if the pc have 2 or less gb!!! Otherwise you won't see any difference. Hey Guys, I've recently lost my Core i7, 8GB RAM iMac and had to move back to an older MacMini 2009 with 2GB of RAM and a 160GB HDD. I find with Lion this thing is running pretty slow and the HDD is constantly churning and grinding away, iStat Menus shows 6GB of SWAP used so it's clear I need more RAM but I really cannot afford anymore DDR3 at the moment so I was wondering if a Windows 7 Feature has any kind of Mac OS Equivalent. I've got a 8GB USB Stick here that's completely unused and I was wondering if I could use it as low priority memory like the Windows 7 Ready Boost Feature. Any ideas guys? Thanks Chris.
