New Desktop Computer Part IV:- Complete - 7 TFLOPS

Tuesday, December 18th, 2012

it’s been a long and difficult birth for this PC, lots of testing and unknowns, to get this created, but here it is:-
andysnewpc12

So what does this computer do, well at idle it consumes approx 200 watts (measured) of electricity, at full load, it uses approx 850 watts (measured) of electricity  to drive an Intel Core i7 990X Extreme Edition processor, and two nVidia SLI GTX 590 3GB DDR5 RAM, that’s a total of 4 GPUs, and the machine’s number crunching performance is approx 7 TFLOPS. (GPU+CPU combined)  The GTX 590 were one of the worlds fastest graphics cards, recently surpassed by the nVidia GTX 690.

Yes, this rig runs very hot, and may need to be water cooled at a later date, or change of case and fans, or radiator based cooling for the CPU, still under testing and development……work in progress!

New Desktop Computer Part III: What is Andy going to do with 48GB of RAM in his Desktop PC?

Sunday, December 16th, 2012

48GB of RAM in a Desktop PC, that’s a server I here you say, other than virtualisation with VMware Player 5.0 or VMware Workstation 9.0, or Client Hyper-V in Windows 8.0, or Oracle Virtualbox 4.0, it does seem a bit extreme, even the latest games, or Adobe Photoshop, you will be hard pushed to utilise all the memory.

Those that are old enough, once upon a time, in year DOS! we used a driver called - ramdrive.sys, that you could load into system memory, and turn some system memory into a ramdrive. RAM was expensive years ago, and only a few kilobytes or megabytes could be used as a ramdrive, but system access was almost instantaneous.

about eight years ago, a company wrote a ramdrive driver for Windows 2000 for clients, to use as a Windows 2000 profile drive for the storage of user profiles for a large terminal server project, to speed up the logon and logoff of users. I’ve been searching for an updated version since, that works with the modern Windows OS, now I’ve found one.

Now with the cost of memory for desktop PCs falling, the following company DR Dataram have produced a new RAMDisk for modern operating systems, and it’s FREE, and allows you to create RAMDisks up to 4GB, if you want to create RAMDisks larger than 4GB, you will need to part with 18.99 USD! It supports Windows XP, Windows 7 and Windows 8, Windows Server 2008 and Windows Server 2012.

Install the software, specift the size

Specify Load, Save and Autosave options

and Hey Presto! you’ve got a ramdrive, out of system memory, and the magic of a ramdrive compared to an SSD, checkout the following benchmarks!

and for the geeks in the audience, that like IOPS

So, this Christmas if you want a fast data disk for your OS, spend your money on RAM for your computer, and bin that SSD (they wear out anyway!)
