updated the list.

 

If you know of something that should be in the guide or on the parts list, LET ME KNOW!!! :mrgreen:

 

Remember, this topic is for the benefit of ALL overclockers, but is written so that the new people can understand it, please help the cause.

 

Edited first post. PM/Email me any suggestions for hardware and anything i may have missed in the guide (remember it is supposed to be for beginners, so if the guide seems too tech-speakish, let me know.)

 

thanks again to all the people that have helped so far, you all know who you are and deserve a tall :beer: and a big :choco:

 

Everyone's opinion of the list is welcome, especially from the "newbies"....afterall, the list and guide ARE FOR YOU!!

I think the Vantec Tornados perform better than the deltas, also the thermaltake xaser 3 case is a good start, has alot of fans and good space, easy to build also :). I have that case with a slk-900u with a 92mm tornado on a Athlon xp 2000 pally, stock 1.75 vcore running at about 33c full load :)

The Beginner's Guide to Overclocking

 

1. To overclock it is best to have a custom built machine, meaning that you built it yourself or chose the parts and had someone put it together for you (companies like Dell, Compaq, and Gateway lock/hide the BIOS options required to OC).

2. After determining that you can change the voltage, FSB, and multiplier-(amd only), you can begin.

3. Remember to start AT DEFAULT VOLTAGES.

4. First raise the FSB (1-2 steps) to see what the sytem can do and test each step for stability and temps. Most of the "Pro's" here recommend using Prime95 and other looping benchmarks to test the stability of the system, you can find them HERE. Repeat this step until the system becomes unstable, then proceed to step #5/6.

5. Next, up the vcore by 1 setting at a time and repeat step #4.

6. If you reach a point where an increased vcore won't allow you to go higher, increase the memory voltage by 1 step (no higher than 2.85v is recommended), and repeat step #4.

 

Key Notes:

1. It is highly recommended that you replace the STOCK HSF before you begin overclocking, any SLK model from Thermalright, Inc. should be good enough, but other options are listed below.

2. Some overclocks require you to "relax" the timings on your memory, know when to adjust them if needed. (see memory timings guide below)

3. IMPORTANT Do not exceed 1.900 volts unless you have extremely good cooling as it will cause severe damage to your cpu. Water cooling is highly suggested for 1.900 and higher cpu voltages.

4. IMPORTANT It is recommended that you do not exceed 50° C when overclocking AMD cpu's.

 

General Guide to Memory Timings

say you have Corsair XMS pc3200 LLpt (low latency)ram.

you have it set to the most agressive timings recommended by Corsair:

CAS 2

Trp 2

Tras 6

Trcd 2

1T command

Now, say you're OC is unstable, and you need to "relax" the timings to allow for the higher system clock, how do you do it?

Here's how:

change the settings to the next highest available (this case on a KD7-Raid)

CAS 2 -> 2.5

Trp 2 -> 3

Tras 6 -> 7

Trcd 2 -> 3

1T command -> 2T command

Please remember, not all settings will be the same for different brands of memory and on different motherboards.

NOTE: this is a trial by error part of overclocking, you may need to vary the settings on the ram to get it to work....this is not a "set-in-stone" rule for memory timings

 

In the event that the system doesn't boot after adjusting the FSB, multiplier, vlotages, or Ram timings, you will need to clear the CMOS on the motherboard. Each motherboard is different so you will need to consult the manual for the location of the "Clear CMOS" jumper, and follow the directions to clear the CMOS. Some motherboard manufacturers offer backup BIOS roms for situations where the BIOS rom becomes corrupted, consult the manufacturer website/customer support for more info.

 

How much time will it shorten the lifespan?

 

 

 

Top Recommended OC hardware (no particular order):

 

Processor (AMD/Intel):

1. 1700xp / P4 2.4C

2. 1800xp / P4 2.66

3. 2000xp /

4. 2100xp /

5. 2500xp /

Note: no 2 cpus are the same (even in the same stepping), but newer steppings tend to overclock better due to core refinements.

 

Motherboard (AMD/Intel):

1. EPoX 8RDA+ Rev. 2 / Asus P4C800-E Dlx

2. Abit NF7-S rev2 / Abit IC7 MAXIII

3. Asus A78nx rev2 / Asus P4P800 Dlx

4. DFI NFII Ultra rev B / Epox 4PDA2+ Rev.2

5. Leadtek nForce2 Ultra400 Deluxe Limited / Abit IS7-G

6. KD7-Raid / Epox 4G4A+

7. Asus A7v8x / Abit IS7

8. MSI K7N2-L /

9. Abit KR7a /

10. Epox 8RDA3+ /

 

Memory:

1. Buffalo PC3200

2. TwinMos

3. Corsair XMS (pretty much any speed/size)

4. OCZ - PC3500-EL LIMITED EDITION PLATINUM

5. mushkin - PC3500 Lvl 2 black

6.Kingston - HyperX pc3500

7.OCZ PC3700EL

 

Video Card (Nvidia/ATI/Other):

1. Gigabyte 9800PRO (with this HSF instead of the stock cooler)

2. Sapphire 9500 PRO (with BIOS flash = 9700 Pro)

3. PNY Geforce4 Ti 4600

4. MSI Geforce4 Ti 4200

5. Chaintech Geforce2 MX400 (the fast SDRAM version)

6. GeForce2 Ti

7. GeForce2 Ultra

**Cards in italics are not the best for 3D games, but score very well in the pit tests when OC'd.

Note: no 2 video cards overclock the same (even same brand/model).

 

Hard Drive(s):

1. Western Digital

2. Maxtor

3. Seagate

 

Power Supply:

1. Enermax 450W PSU

2. Antec TruePower 430

3. TTGI 450 (or any other model)

4. Antec TrueBlue 480

 

 

Cooling

 

Thermal Paste:

1. Arctic Silver Ceramique

2. Arctic Silver (3 or 5)

3. Shin Etsu

4. RadioShack silicone heat compound (actually rates better than you'd think.)

 

Heatsink (AMD / Intel):

1. slk800 / slk900U (both are from Thermalright)

2. Thermaltake volcano 11 / Coolermaster Aero 4

3. Zalman7000A-Cu

 

Fans:

1. Smart Case Fan 2 (Thermaltake)

2. Vantec Tornado

3. 80/92mm Delta (very loud, but great cooling)

4. AOC 80mm Aluminum Fan (carried by CompUSA)

 

Case:

1. Lian Li

2. Codegen (most fan mounts in any case i've seen)

3. chieftec's Aluminum Dragon

4. Thermaltake's XaserIII (good starter case)

why only AMD cpu's? AMD's handle heat better than p4s.

torrey, what do you mean by that?

 

all the hardware in the list is from what fellow OC'ers here at the pit have suggested, the listings (or lack thereof) for any particular component is EXACTLY what was provided....nothing more, nothing less.

4. IMPORTANT It is recommended that you do not exceed 50° C when overclocking AMD cpu's.

that should say Pentium4...

 

amds can tolerate up to 85-90degrees...pentium4s...75....

 

nothing wrong if your AMD is at 60degrees. not saying you should keep it there, and that u shouldnt do anything about it...

Hey this is great INTRO for me cause my friend gonna try OC my comp i want to try it myself i have alrdy posted a forum for my comp on other page and i need #%^*! much help as possible.

EXcellent i rate this.

Well explained since i have a 1700+XP Athlon

i'm glad it could help you.

 

now if only other ppl would post their thoughts/comments on the guide's usefulness.........

Yep just coming back to reread. Have we or should we include something on clearing the Cmos after a failed oc? Possibly something about flashing board bios and vid bios. Perhaps the latest flash instructions for the FX cards that's been floating around. Just a thought. Maybe even a small piece on the advantages of using Clockgen. :)

i need to catch up on some of it (the FX cards especially). i'll add it in as soon as i can though.

you may want to add definitions to terms such as vcore and fsb. I consider my self to be a beginner oc'er, being that i have only oc'ed a video card, but i know some of the stuff you are talking about. also, you may want to tell beginners what to look for so they know that their system has become unstable.
