තනි ඇහැට ඇඬෙනවcooling method : liquid nitrogen and liquid helium minus 223c
AMD said in a blog post that the eight FX processors had been overclocked at speeds up to 8.429 GHz,
beating the prior record of 8.309 GHz, using a third-party team of overclocking enthusiasts.
More importantly to the average consumer user, however, AMD found that the company's FX chips could reach over 5 GHz
using normal air cooling or water-cooling rigs that cost less than $100.
"Based on our overclocking tests, the AMD FX CPU is a clock eating monster,
temporarily able to withstand extreme conditions to achieve amazing speed," Simon Solotko, a senior manager with AMD,
wrote. "Even with more conservative methods, the AMD FX processors,
with multiplier unlocked throughout the range, appear to scale with cold. We also achieved clock frequencies well above 5GHz using
only air or sub-$100 water cooling solutions."
Guinness is expected to certify the record, an AMD spokesman said Tuesday.
AMD's announcement opens the Intel Developer
Forum here in San Francisco, a developer conference hosted by AMD's
arch-rival and much larger competitor, Intel.
What is overclocking? Historically, overclocking was a practice begun in the early days of the 486 and
Pentium where a microprocessor was pushed past its rated speeds. Microprocessors are generally "binned," where each
chip is tested to determine the fastest speed at which it can operate before it starts generating electrical faults and/or
incorrect results due to the heat it itself produces. Within a PC, notebook computer or phone, these chips are generally either
air-cooled using a series of "fins" that distribute the chip's warmth to the outside air via a fan.
A sealed network of tubes, filled with water, can also be connected to a copper-based "heat sink," which thermally conducts heat away from the CPU.
Overclocking a chip can void its warranty, however, meaning that it's generally a risky practice even for enthusiasts.
An overclocked chip that fails can essentially be destroyed, as can the motherboard or chipset components.
Extreme overclocking uses liquid helium and nitrogen to cool the chips; liquid nitrogen can push the chip's temperature
down to less than negative 180 degrees centigrade. The risk here is a "cold bug," which can also prevent the chip from working.
Fortunately for AMD, the team of overclockers found no such bug.
AMD's FX chips represent its enthusiast line of high-end chips,
which are "unlocked," allowing users to set its operating voltage and clock
speed multiplier in order to overclock the chips.

මචන් processor එකක් overclock කරනව කියන්නෙ සරලව කිව්වොත් ඒක හදල තියෙන ,
නැත්නම් ඒක වැඩ කරන්න දීල තියෙන clock speed එකට වඩා වැඩියෙන් ඒ processor එක ක්රියා කරවන එක.
ඉතින් ඕක කටින් කියන තරන් ලේසි නෑ බලන්න ඕනෙ ගොඩක් දේවල් තියෙනව
විශේෂයෙන්ම එහෙම කරද්දි වැඩියෙන් voltage එකක් දෙන්න වෙනව processor එකට ,
ඒකෙ අතුරු පලයක් තමයි අධික රත් වීම, ඉතින් ඒක නිසා තමයි ඔහොම extreme conditions යොදාගෙන ඕව කූල් කරන්නෙ ලොකූ clock speed වලට overclock කරද්දි.
ඒත් අපිට අපේ ප්රොසෙසර් ඔහොම overclock කරගන්න පුලුවන් යම් තාක් දුරකට එක්කො තියෙන කූලර් එකෙන්ම ,
නැත්නම් හොද air හරි water හරි කූලර් එකක් අරන්.
මේව කරන්නෙ එක්කො motherboard bios වලින් නැත්නම් software එකකින්
කරන විදි ගොඩක් තියෙනව CPU multiplier එක වැඩි කරල නැත්නම් බහුලවම FSB (Front Side Bus) එක වැඩි කරල
මොකද ගොඩක් CPU වල multiplier lock කරල නිසා.
මෙතන නම් කරල තියෙන්නෙ CPU multiplier එක වැඩි කරල.
මෙච්චර තඩි ස්පීඩ් වලට නොගියට අපිට ගොඩක් ප්රොසෙසර් තියෙනවට වඩා සෑහෙන දුරකට OC කරන්න පුළුවන්
මේකෙ වාසි ගොඩයි කියන්න කම්මලිනිකමට කල්පනා කරන්න 2.6 GHz processor එකක් අරන් ඒ ප්රොසාට වඩා රුපියල් 10, 15 දාහක් වැඩි 3.2 GHz එකක ගානට OC කරගත්ත නම් සල්ලි ඉතුරුයි
ඒ වගෙම හරියට කරොත් හරි නැත්නම් ප්රොසාගෙ සහ බෝඩ් එක ඇතුලු ඒවයි ආයු කාලය අඩු වෙන්න පුළුවන්. ඔක්කොම අඟුරු වෙන්නත් පුළුවන්
