Overview of OCing
So you just bought your new system eh? With your cool X2 processor or freakin AMD 64 3200+ Venice, that you want it to do like 3.0Ghz like you see everywhere. But you dont know squat about OCing, well you came to the right place
. After you installed everything, make sure you run your comp on all stock settings for around a week or two. This is called the burning-in period
. After the thermal grease has settle and the silicon expanded and what not it is time for you to do it. You OC through the bios, when you start up your computer you either hit delete, or any combinations of the F keys. Once your in the bios, I would say familiarize your self with it like its your own house. Go through all the sections, settings, etc. Once you get to know your bios, find the HTT/FSB speed. This is the main part of your OCing, this is what makes your processor go faster O.o. You need to up this about 5mhz increments, and everything you do it I would suggest you run prime95 for about 12 hours or 24 hours to be on the safe side. Once you get to the point you start to get errors in memtest or prime95, it is time to raise the VCORE or the DIMM voltage. This raises the voltage obviously lol, you will need to raise this in 0.25 increments for the VCORE and the DIMM voltage .5V. If that doesnt help its obviously your ram crapping out on you and it doesnt want to go any higher, thats where the memory dividers come in. LOOK UP! If that still doesnt work, add more voltage, and if it doesnt, then you either get a crappy cpu, a bad working psu, or just you got a bad mobo. Those are the three main causes of why you cant OC any further. Obviously you cant just raise the VCORE to like 5.5V or your cpu will fry on you and the temps would be outrageous. The max temp for an AMD 64 processor for me would be around the 35C for idle and 55C full load. Once you reach the 250FSB/HTT mark you will need to lower the LDT multiplier, but on most mobos they do this auto and lower it for you so you dont have to worry about it.
In memory timings, you always want the first number the lowest, the CL timing. 2 is ideal, 2.5 is just average, and 3 is way to high :shocked:. If your OCIng and your producing many memtest errors, its time to adjust the timings. You would first start out at raising the CL timings up .5, so if you were at 2 raise it to 2.5 and add more DIMM voltage. 2.85 is probably a good voltage for regular ram, but some types of other ram like upwards 3.3V. If you can get that stable, you would want to lower the timings. Usually the second number the ras to cas would be higher then the ras precharge which is the third one
CAS latency RAS TO CAS RAS PRECHARGE ACTIVE TO PRECHARGE
Usually it is best to leave the last number high on some types of chipset. So if your stock timings are 2-2-2-5 and you cant OC any more try 2.5-2-2-5 then if you can get that stable try to tighten the timings to like 2-3-2-5, and try some different VDIM voltages.
OCING YOUR VIDEO CARD
To OC your video card is simple, you download aTiTool for ATi cards or rivatuner for nVidia based cards, and then you simply start the program up, increase the core speed and memory speed 5mhz increments or 3, and then play your favorite game, not minesweeper something more like BF2, FEAR, HL2, which is very sensitive to OCing your video card. Make sure you also watch your temps to your video card, the video card would take temps upwards to 80C but most people keep it around 50C. Usually the GPU runs hotter then the CPU unless you have some nice super water cooling. This is why people buy after market heatsinks with AS5 and stuff so they can OC farther sense usually the thing holding them back in the heat. If your playing your game and you see dots, or slashes of lines, that means you OCed too far. You will need to downclock a little bit. The reason why you are getting these lines are that the GPU is heating up and can not produce those, or you just got a bad video card like just like you could get a bad CPU. If you OC too far you could also fry your video card . Just make sure you go up slowly, play your game for a couple of hours or minutes rofl, and then keep going until you could get the most stable OC out of your video card. Usually before you want to OC, you want to get a reference, you would want to run 3dmark03 or 3dmark05 and copy that score down, then OC your video card and then see how much improvement you can get
im not sure if this will help i just wanted to post it rofl
What happens if you OCed too far for your CPU
Well all you have to do is put the CMOS jumpers from 1-2 to 2-3 and then leave it there for 10-30 seconds and your done, if that doesnt work refer to your mobo manual or take out the CMOS battery for around 10 minutes.
THE MHZ WARS ARE OVER
Processors are traditionally rated and advertised by their speed. Computers would be advertised as athlon xp 1.5GHz or athlon xp 2.0GHz. The more gigahertz (GHz) the faster they go. What most buyers don't realize is that in terms of construction, a athlon xp 1.5GHz thoroughbred is identical to a athlon xp 2.17GHz. So why is there a difference in speeds? When a batch of processors is built, different processors in the same batch will have different tolerance levels. In a single batch some processors will only be able to run at 1.5GHz while others can run 1.7GHz, 1.8GHz or 2GHz and so on. This rating is known as the "clock speed". Ideally, processors will be sold at the maximum speeds they are capable of operating at and bring the largest amount of profit to the manufacturer. But as faster processors cost more than the slower ones, demand for the latter is usually higher. In order to meet the market demand, the manufacturer marks processors capable of running at 2GHz at the speed of 1.5GHz units. Because of this, some "slower" processors can happily run at a higher speed. The same thing happens to video cards and ram so if your building a OCing system do your "homework"
