Help on Motherboards Overclocking FAQs

post #1 of 2
Thread Starter 
Hi everyone, for three months, I've been searching and reading about overclocking. And I've liked the idea very much. After almost everyday of two hours of searching through that period, I found myself confused with no answers about particular things.
So I thought that my last chance is to ask you. And I hope find some answers.

All I've found about overclocking are some beginners' tutorials, which say that overclocking is about increasing the frequency until such a device become unstable then increasing the voltage a little bit then increasing the frequency then ….. so on ( and of course you need good cooling)………. Now, if that was for the beginners so that is for experts, in other words, what can it go farther than that??!!.
Another point, is it true that as long as I can increase the frequencies and voltages and have a good cooling system, I will still gain speed and performance??!!.

While reading other guys overclocking results, I surprised that all the results were similar. I mean 2000 GHz CPU overcloked to 2800 or 2007, 2400 to 3100 or 3200, 3200 to 3900 or 4000. so why it's always the same values that can be gained despite of the differences between specs or coolers and whether it is Intel or AMD.!!!???

In fact, I get much interested in overclocking my GPU than CPU cause of games. But there are no much discussions about that over there. And if there are, so they don't talk about voltages raising , just about frequency, and no one of them reached my results (of course considering that they have the same card like mine). I have Asus Radeon 9550 128 Gamer edition I'm using Ati tools and get up to 460 MHz core , 280 MHz memory. And it's stable like rocks. Scored 4000 3dmark 03.

My motherboard doesn't support voltage value changing and only 4 X AGP. So do you think that I'll gain more performance for my AGP card if I get a new one? I'm planning about 800 MHz core, 600 MHz memory.

When I decided to buy a new overclocker MOBO I get back to Google and searched.
But no good news, a lot of MOBO and a lot of features and none of them tell how far the CPU, memory or AGP voltage can goes? A lot of choices but don't know what to buy. I thought you can help out.

My specs are (I got this machine three years ago): Intel P4 2.4B full cache, GA-8IR 533, Radeon 9550 128, 256 x2 DDR SpecTEC ram 333, PSU discovery 250 W (I've tolled that it's not enough for overclocking??????).

I know I've written a lot but I need to get a clear view about the topic.
I depend on you guys.
All responds will be much appreciated

Welcome to the forums.

It sounds like you've already done a bunch of homework. I'll "assign" you one more guide to read. It's what first brought me to this site (found it on a Google search), and I found it to be very helpful in bringing together all of the various concepts. Yes, there are definitely lots of things to juggle, and no two computers overclock quite the same way. Understanding all of the various concepts, being willing to tweak and test, and most of all, being extremely patient is the only way to overclock well.

Increasing frequencies is where you get your performance gain. Voltage increases are typically made to add stability to the system (i.e. upping voltage itself rarely, if ever, directly increases performance). But yes, as long as you can push your RAM, CPU, and/or GPU harder and faster, you should continue to see performance increases as long as the system is stable.

In general, overclocking results vary widely from system to system. If enough systems were tested, it would probably graph out to a bell curve (few lousy and excellent OCs, lots of decent ones). The whole concept of overclocking is pushing components beyond their specified speeds. The "extra" capacity in components depends on a multitude of factors from how many specs of dust ended up on the PCBs to how badly manufacturers want to get rid of inventory (e.g. ATI selling the x800gto2 with the x850xtpe core). Those variables apply to each and every component, so there's no accurate way to predict how a particular system is going to overclock, though it's not usually too hard to guess what might be typical for a system.

ATI Tools is a great program to overclock GPUs. The single best thing you can do for your GPU is add some aftermarket cooling. Upping AGP voltage is potentially dangerous and may not help out all that much. I would say that 800/600 on your card is not possible, regardless of what tweaks you make to it. There are absolute physical limits to how much components can overclock under ideal conditions, and it's not much of a stretch to say those numbers are well beyond that card.

You are correct about most motherboards not sharing the extents of their options. Your best bet is to browse/search for threads about motherboards of interest on here as you'll get first hand information as to how they perform and the options they offer.

You're also correct that a 250 Watt PSU is going to be a quick dead end in your overclocking pursuits. Not only are the Watts important, but the amperage (both strength and stability) on the various rails (3.3 volts, 5 volt, and 12 volt) are critical to a good PSU and thus a good overclock.

I'm not sure if I cleared anything up or if I made the picture muddier for you. Post back any questions you have. Also, to save time and help us help you better, click on the User CP linked near the top left of every page, and enter your system specs in the location provided. That way, your gear will show in all of your posts.
