hypertransport clock frequency are based on the CPU frequency!
We finally see the long-awaited memory divider. How can we use the memory with the CPU? We have the following formula:CPU frequency/memory divider = DDR/DDR2 memory bus frequency = DDR/DDR2 memory operating frequency * 2
* Note: If memory divider is not an integer, for example, 4.6, you must set memory divider to 5 to avoid Memory overclock operations.
For amd AM2 athlon 64 3200 +, the CP
Link of the question is here: ACM ultraviolet 108-Maximum Sum
The two are actually related. 507 is a one-dimensional maximum interval sum problem.
Any N * m rectangle:
A11 A12... A1NA21 A22... a2n.....................AM1 AM2... Amn
It can be regarded as a one-dimensional array with the value: (A11 + A12 +... + A1N), (A21 + A22 +... + a2n ),..., (AM1 + AM2 +... + amn ))So the sub-rectangle of the maximum N

, the result is different. If you use the stack area, if the variable address is am1-am2 so large, exit B calls when the address is released, the C function may overwrite the memory, so that when D executes, the content read from the memory am1-am2 is changed.And if you allocate with new (heap), that is not the case, because there is no display of the pair with delete and the heap is shared with the thread,
radiator installation graphics and text tutorial
Today's water-cooled radiators tend to be highly compatible, typically with mainstream computers on both Intel and AMD platforms, and the Intel and AMD platform slot interfaces generally include:
The Intel platform mainly includes: LGA2011, LGA1366, LGA1156, lga1155,lga1150;
AMD platform mainly includes: FM2, FM1, am3+, AM3, am2+, AM2.

Yingxiu's T-series motherboards are well known for their solid workmanship, rich onboard equipment and accessories, and are highly prized by DIY players for their strong overclocking capabilities and good stability. In particular, TForce550 in the AM2 platform has achieved great results, of course, and AM2 the processor itself, but its own performance advantages believe that we are also obvious to all. In r
is basically kt266/333/ 400 and p4x333/400/533, as long as the South Bridge is VT8235, 8237 not to mention; the SIS chipset has sis740/745/746/748 and sis650/651/648/655, as long as the South Bridge is SIS962 above also no problem.
The above mentioned three kinds of South Bridge are three of their first support USB2.0 of the South Bridge chip, as long as the motherboard support Usb2.0,bios settings in the boot Device option will have a USB device optional, you can support U disk boot. After th

Upgrade a user, go to the computer city of a merchant's store, ready to purchase for upgrading of the CPU and motherboard, his choice is the AM2

Fedora is not as fast as the final release version. this is part of the reason why Edgy Eft 6.10 and Zod are added in this test. both Fedora Core 6 (Zod) and Ubuntu 6.10 (Edgy EFT) were released in July. the new Ubuntu 7.04 (Feisty Fawn) has been released, and Fedora 7 was released on July 7, May this year. originally, Fedora 7 was intended to be released at the same time with Feisty Fawn, but it was extended for one month due to some development problems.

chipset often used Uli's Southbridge chip, but soon it was acquired by Ati's rival NVIDIA.
The sb600 nanqiao chip can be used together with ATI's many beiqiao chips, including radeon Xpress 3200, 1600, and 1100. It supports four sata ii hard disk interfaces and disk arrays in RAID 0, 1, 0 + 1, and other modes. Sb600 also provides support for ncq local command Sorting Technology and ahci.
The sb600 can also provide up to 10 USB interfaces and 6 PCI slots. However, generally, the motherboard manu

According to the word length of the processing information, it can be divided into: Eight-bit microprocessor, sixteen-bit microprocessor, thirty-two microprocessor and sixty-fourteen-bit microprocessor. Mainstream CPUs are provided by AMD and Intel. Such as amd athlon64 X2 5000 + AM2 and Intel Core 2 Duo e7200. 2. In-memory and auxiliary
When finding linear equations, the coefficients and their respective locations are very important. When changing, the order of the equations must be maintained, therefore, we often arrange the coefficients of the unknown in a number table of a rectangle.
For example, Linear Equations
The coefficients are arranged in a rectangle number table according to the original positions of the equations:
,
We call this rectangle number table as a matrix.

When someone saw the title of the Linux optimization Guide, they were sure to say, "Do you need to optimize linux ?". Before answering this question, I first asked the question "What is Linux optimization ?", My idea is that there is no optimal solution. what suits me is better. Isn't it optimal to adjust the desktop background to your favorite color?
I don't think you need to answer either of the above questions. If you are interested, you can continue. The optimization mentioned here mainly re
