A guide for C2D Overclocking

Part1. Tidying Up Your BIOS (not all BIOS may have those options)
*You must update your BIOS to the latest version before proceeding*
1. Disable AI Tuning for ASUS ,C.I.A.2 for Gigabyte
2. Set PCI Express (PCIe) frequency @100Mhz (Auto for DS3/DS4/DQ6)
3. Set PCI frequency @33Mhz
4. Disable Hyperpath 3 (for P5W DH only)
5. Disable any spread spectrum
6. Disable Q-Fan (for ASUS only)
7. Disable Limit CPUID Max to 3
8. Disable any overvoltage protection
9. Disable C1E
10. Disable EIST
11. Disable Virtualization Technology
12. Disable No-Execute Memory Protect
13. Disable any other thing you don’t use
14. Do not enable any speed enhancements you see
Part2. Memory Adjustments
**Expand options for Gigabyte BIOS under M.I.T. by pressing CTRL+F1**
Gigabyte: Set Memory Multiplier to 2 (1FSB:1RAM operation)
ASUS: Set DRAM Frequency to DDR2-533 @266Mhz FSB (1FSB:1RAM operation)
As you increase the FSB, the RAM will follow in the pattern of 1:1 shown in BIOS.
1. Set DRAM Timing to manual or disable SPD (use SPD for P5W DH)
2. In BIOS you will see 4 separate timing digits, change them to the ones specified on
your RAM
e.g. 4-4-4-12
CAS# Latency (tCL)
RAS# to CAS# Delay (tRCD)
RAS# Precharge (tRP)
RAS# Precharge Delay or Active to Precharge (tRAS)
When 1FSB:1RAM is overclocked above the rated frequency of your RAM use the
following values
Timing: 5-5-5-15
vDIMM: 2.2V
e.g. DDR2-667 4-4-4-12 1.9V operating at ~400Mhz will need to be set to 5-5-5-15 2.2V
3. Leave the rest of other timings either at Auto or at their default values
Part3. Voltage (again not all BIOS will have the option or uses different name)
***The following voltages are to be used with Part4***
1. Set DRAM/DIMM Voltage (vDIMM) to 2.1V or 2.2V if specified by RAM (+0.3V or
+0.4V) and as you are Overcloking even if your default volatage is 1.8 set it to 2.1
2. Set MCH Voltage (vMCH) to 1.55V
3. Set FSB Voltage (vFSB) to 1.40V
4. Increase SB Voltage (vICH) by +0.1V from default-lowest value
5. Set CPU Voltage (vCore) for the following CPU
E6300=1.370V E6400=1.375V E6600=1.400V E6700=1.400V X6800=1.400V
Part4. Frequency Control
First attempt:
1. Set CPU Host Clock/Frequency (FSB) to 333Mhz (300Mhz for X6800)
2. Set CPU Clock Ratio or Multiplier to the default value for your processor
E6300-> 333*7=2331
E6400-> 333*8=2664
E6600-> 333*9=2997
E6700-> 333*10=3330
X6800-> 310*11=3410
3. Save settings and reboot
Further attempts:
1. Up even more FSB by 5Mhz or 2Mhz increasement
2. Calculate your final clockspeed
3. Up even more vCore if needed by 0.025V increasement
Part5. Stability Testing
You will need the following programs:
– Prime95
– Memtest86+
– Core Temp
– SpeedFan
1. Fire up CPU-Z and keep it running in the background to monitor clock speed
2. Fire up Core Temp to monitor temperature but since Core Temp is not so accurate use
3. Fire up SpeedFan to monitor voltages
3. Run dual instances of Prime95 in torture mode for 2 hours
4. (Optional) Run Memtest86+ for 2hrs
5. If stable go to Part4-Further Attempts, if not go back to last stable frequency
6. Once you’re happy with the settings proceed to the final part
Note1: The higher the final clock speed, the lower the temperature for CPU has to be to
maintain stableness
Note2: vCore should not fluctuate by more than +/- 0.100V. If it does, improve cooling
Note3: If an attempt fails and the computer doesn’t boot, hold down Insert key when
booting to restore default settings in BIOS
Part6. Finalising
-Lower vCore by one notch at a time until lowest possible while maintaining the same
-Do the same for vMCH, vFSB, vICH after the above step is completed
-Record the BIOS settings which works (except DFI and ASUS owners)
-(Optional) Pull off a PCMark and/or SuperPi32M score and compare to stock to gauge
performance increase
P.S. Thx to THG,ASUS,Gigabyte forums and specially GOOGLE
P.P.S. If u r not able to boot then try clearing ur CMOS Battery

Phunny PHP(easter eggs)

Friends Don’t Know why but I like PHP From starting . First I laugh at its fullform Hypertext Preprocessor . There are still Four thing that I use every day

  1. MS DOS
  2. Wordstar (I create most of the documents only in wordstar)
  3. PHP Scripts and Ebook
  4. Internet

Most of the program have some secret codes/output function the reasons are Explained In previous posts . So here are the list of some PHP Easter Eggs .


For seeing phpinfo() paste this code at end of PHP based URL






Just paste this code at end of URL of PHP Based Server





it is said that the dog picture is shown instead of the logo in the call to phpinfo() when the date is first aprill from this code



Paste these Codes at the end of url on PHP Based Server





According to some People
“The PHP Logo and Zend logo eggs are NOT eggs, they are documented as  php_logo_guid() and zend_logo_guid()”

Easter Eggs

Easter EGGS


  1. In the context of software an Easter Egg is a hidden feature or novelty that the programmers have put in their software .

A true Easter Egg must satisfy the following criteria:

Undocumented, Hidden, and Non-ObviousAn Easter Egg can’t be a legitimate feature of a product, or be an obvious part of a storyline. Easter Eggs will usually stand out either because they totally don’t fit with their context (like a pinball game in a word processor), or because they have a deeper hidden personal meaning to the creators, so they threw it in for entertainment.

ReproducibleEvery user with the same product or combination of products must be able to produce the same result given the instructions. If others can’t reproduce an Egg, then it doesn’t belong in this archive.Put There by the Creators for Personal Reasons
The Egg must have been put there on purpose, and furthermore have a personal significance to the creators beyond just making a better product (movie, TV show, software program, etc).

Not Malicious
Easter Eggs are there for fun, not to do damage.

The most important element… if it’s not there for entertainment, it’s not an Egg.

Reasons?Behind?Putting Easter?Eggs

As a Signature – In the software world, many programs are released simply under a company brand, with no mention of the individuals who put in a lot of work on the product. So you often see Easter Eggs listing the people who worked on the project as a sort of hidden “We made this!” signature.

As an Inside Joke – Most groups of people who work together for a while develop their own inside jokes. Sometimes these inside jokes get slipped in as Easter Eggs, into Software, Movies, Music, etc. Often, an outsider would either not notice or be confused and not understand these Eggs, but that’s the point – they are inside jokes.

Vanity – Directors will sometimes make uncredited appearances in their own movies as some bit part, and only people who actually know the director are be able to tell. Sometimes they’ll also cast friends or relatives in parts also for kicks.

Tribute – An author or director might want to pay subtle tribute to someone or something they admire. For example, if a book is made into a movie, the original author may appear in an uncredited bit part.

To Add Something Personal – They put something in for no good reason other than just because they want to. Like Jerry Seinfeld hiding a Superman reference in every episode of his show.

AMD 3500+

AMD 3500+

AMD 3500+ is the fastest single core available in the market by AMD.Even though AMD has a faster single core than AMD 3500+ which is 4000+ but it is rarely available.AMD 3500+ is available in 2 forms Socket 939 and SocketAM2.Socket 939 is dead but Socket AM2 has no noticeable performance difference over Socket 939.

AMD 3500+ Venice Core (Socket 939) carries 512kb of cache in the 2nd level and runs at 2.2 GHz and it achieves this clock speed by having a multiplier of 11 and a FSB of 200.It runs at a stock voltage of 1.350v which is quite good so as to maintain the heat level and will also help in Overclocking. Overclocking is also favoured by the fab process AMD 3500+ is made of which is 90nm which is better than its precessdors.AMD 3500+ is available in many cores like Manchester,Venice,Windsor.Of this Vencie is the best as it has a revision of E6 which is the latest revision of AMD 3500+ which means better performance and more Overclocking potential.
We used an ASUS A8N-Ealong with a GB of ram in dual channel and reached a maximum stable overclock of 2.7ghz.As you people can see an overclock of 500mhz is quite good and after Overclocking AMD 3500+ can beat the X2 3800+ easily in benchmarks and came quite near AMD X2 4200+ in terms of performance. The 90nm fab has done real good for Overclocking and later on as new revisions come out the Overclocking potential of AMD 3500+ will increase.
