4x Radeon HD 7990 Mining Monster Rig (8 GPUs)

Cryptocurrency is a type of digital currency that is based on cryptography. Cryptocurrency uses cryptography for security, making it difficult to counterfeit. Public and private keys are often used to transfer the currency from one person to another.

Cryptocurrency is considered a counter-culture movement related to cypherpunks, who advocate the use of cryptography as a route to social and political change. Cryptocurrency presents a form of this movement in that it is essentially a fiat currency, which means it only has value if people agree to such and use it as a medium of exchange. However, because it is not tied to any country, its value cannot be affected by a central bank. In the case of Bitcoin, the most prominent functioning example of cryptocurrency, its value is determined by supply and demand in the market. As such, this currency behaves much like gold and other precious metals.

Memory Usage: Android 4.2.2 vs Windows 8.1

This result may be surprising to many Android users.
It’s just that Android 4.2.2 (Jelly Bean) uses more memory than desktop version of Windows 8.1 x64 RTM, but unlike Windows 7 and 8, Windows 8.1 requires more memory to start up.

If you remember, I was able to run both Windows 7 and Windows 8 on 128MB of RAM. However, Windows 8.1 requires 256MB to boot (at least running stable), 512MB for installation and 1gig to run comfortably.

Impressive, isn’t it? 😉

It’s time to break some records!

Today I bought Corsair Vengeance 16GB Quad Channel DDR3 Memory Kit and decide to break some benchmark records. I’m not using Liquid Nitroge only water cooler with custom fans.
It will be really hard to get to the Top 20 Resultshwbot.org

Before we look at the numbers, let’s take a brief look at the test system that was used. All testing was done on Windows 8 Pro 64-bit operating system.

Noisy Beast
– First Ever build 2013

Noisy Beast - Build 3     Noisy Beast - Build 6

CPU: Intel Core i7-3930K @ 4.8GHz (1.445V, max 72°C)
MB: Asus P9X79 Pro (Bios 4302)
Mem: Corsair Vengeance 16GB DDR3-2400 (CMZ16GX3M4A2400C10)
SSD: Samsung SSD 840 Pro Series 256GB (Firmware DXM05B0Q)
PSU: CoolerMaster Real Power Pro 1250W (RS-C50-EMBA-D2)
Cooling: Corsair Hydro Series H100i Water Cooler
Paste: Coollaboratory Liquid Ultra
Fans: 2x Koolance FAN-12038HBK-184 – 59.0dBA @ 4000 RPM
(according to xbitlabs.com review – 76.5dBA @ 4000 RPM)

Good optimization is key to success – it’s over 64GB/s !

Browser Wars 2013 Part 1 (January)

Browser Wars is a metaphorical term that refers to competitions for dominance in usage share in the web browser marketplace. The term is often used to denote two specific rivalries: the competition that saw Microsoft’s Internet Explorer replace Netscape’s Navigator as the dominant browser during the late 1990’s and the erosion of Internet Explorer’s market share since 2003 by a collection of emerging browsers including Mozilla Firefox, Google Chrome, Safari, and Opera.

ReFS vs NTFS Benchmark

ReFS (Resilient File System, originally codenamed Protogon) is a new file system initially intended for file servers that improves on NTFS in Windows Server 2012. The project originally started out as Monolithic NTFS (MNTFS) and then ended up codenamed Protogon before the final ReFS naming was chosen.

Microsoft claims ReFS has been built from the ground up, to meet the demands of the storage requirements needed by Windows users. It offers the ability to handle large storage volumes (maximum volume size of 1 Yobibyte), shared storage pools across multiple machines and enhanced resiliency to corruption.

Surendra Verma, the development manager for the Storage and File System team wrote:

“ReFS inherits the features and semantics from NTFS including BitLocker encryption, access-control lists for security, USN journal, change notifications, symbolic links, junction points, mount points, reparse points, volume snapshots, file IDs, and oplocks.”
