Lets all overclock!

Overclocking is fun:) Unfortunately, on my moms comp, the bios doesn't support overclocking :(
But the motherboard for my dads future comp does (in nice 1mhz increments, which is even better!)

Now, what is overclocking?:
Overclocking is when you tell the processor to do more than it is supposed to do. This makes it faster. You should have a massive heat sink and fan, though, or the extra heat could melt the CPU, creating a several-hundred-dollar piece of jewelery. Also, each chip has its fail point. When you buy, say, a 1ghz CPU, Intel may have tested it and found it would work up to 1.31ghz before failure: ie, it wouldn't work right and would crash, necessitating a reboot. But you don't know the failure threshold, and if you brougt it up to 1.3ghz, it might work fine, but if you brought it up to 1.35ghz, it might start crashing. So just keep adjusting it, and once you've found the limit, tone it down about 5%, just to be safe and trouble free. And Don't overclock if you dont need to (ie, you will only be using Corel Wordperfect, or solitare, during that session)
To overclock, go into startup when you boot the computer (usually just press delete of F1 alot). Once there, find the overclocking option, and adjust it. Then save and exit

So, how much do you overclock?

Sometimes, overclocking too high can cause massive problems. I've heard rumors that GeForce cards do not like overclocking...

Well when you overclock the CPU you overclock the PCI and AGP bus as well. There is no way o cool them. Which is why I don't, because I only have a 6x multiplyer I could get maybe 50MHz before risking damage. But say a P3 with a 100MHz bus, they have an 8x miltiplyer so they can overclock much higher.

ive overclocked my duron 800mhz to 1.1ghz, but dont overclock it any more cos fan was always too loud and 800mhz is good nuff for me

be carefull when overclocking AMD 's they get pretty hot !!
the best CPU's i ever over clocked was the intel celeron's ! but doing it with the old way ! ( jumpers ) :D

I don't think overclocking is as common anymore, because the processors are so fast now. Not at least like the old days when everybody was getting a 300 MHz Celeron and taking it to 500

This would explain why my screen went black when I used the gigabyte supplied software to wind my 950 duron up to 1100mhz.

Geforce1 DDRS are the only ones that really like to be overclocked. I got another 15FPS in Quake 3 when I overclocked mine.

I soft o/clocked my Celeron 500 to 566 (off the top of my head) but then it locked.

I won't over clock my Athlon 1.4 at all as it runs at 56 degrees as it is with a volcano HSF and 2 extraction fans cut into the case. Maybe if I decide to watercool I'll do it, but I'm not really into it anymore.

hrmm sounds like a good idea...i have a 800mhz celeron and i dont know what it can handle but what kinda temperature do i need to keep it in?:confused:

Yea, when I had a PCI video card (16mb Voodoo 3), my screen was always black. I couldn't even get to the BIOS to change it back:eek: But, there was a jumper on the mobo to restore default settings, so all was well.
Now, it just doesn't like it. I think the RAM is the problem, as windows starts to load, but never finishes. That was overclocking my system bus (max, 1.91 ghz on my Athlon XP 1800).
Then I just switched my CPU VCORE SELECT. It starts a 6, and goes to 14, giving a range of 800 to 1860 mhz cpu at stock system speeds (total, 2.3ghz CPU. Which would probably kill it, as it is 50% higher than stock) I was thinking of keeping it a 13, giving me 1.73 (200mhz higher). I have a ThermalTake 7, copper fins with a 53cfm fan on it. And the chipset has a heatsink and fan. It is weird though, because windows and startup don't recognize the processor as being faster. So I am leaving it on 'default' for now till I figure out what is wrong. So I will leave it overclocked a measly 40mhz for now:(

Thanks dill hole, i hit f2 to get into setup (windows me), got a keyboard failure and it screwed up the mouse. I was actually gonna "underclock" because my video card has been goofin since got a new format for it.

The only reason I can think that happened is if you have a wireless keyboard. Otherwise, I would suggest just setting a jumper to restore default BIOS settings if you really want to underclock it.

so what is a good temp for my 800 mhz celeron, i look in bios and it says i can do like 14x regular speed which is preety fast, i dont think it would be a good idea tho.:smoker2:

Well, 120 F is about as hot as you want to get. Celerons handle overclocking very well.

BTW, I just read your sig. :spit:

That 14X faster is the speed your CPU is told to run in relation to the bus. You probably have a 100mhz bus, so yours would be 8X by default. So 14X would be 1.4ghz, or 1400mhz.

PS, I know someone with an 800 that runs a 1100. But thats just him.

I managed to get my 1200Mhz Athlon Thunderbird to 1553 before I started having problems.

Hmm, I guess you don't know what the hell watercooling is. Watercooling has special blocks for the AGP/PCI cards. It uses a pump to pump water threw cooling blocks that are on the CPU, and other main components

Watercooling is also hella pricey.

How about liquid nitrogen? Some guys got their 2.2ghz P4 to 3.7ghz.

my cpu is a 400 but its overclocked at 401...is that good enough? I didn't even have to do it myself, it came like that:)

Really? I didn't know they made water cooling blocks for the PCI and AGP. Neat stuff!

And not too long ago I found another liquid cooling option for the entire mobo. I was watching The Screensavers and they bought some liquid from 3M that is totally non-conductive. I don't remember the name of it, but they submerged the mobo in it and ran the fluid through dry ice to cool it. Needless to say there is a point that is too cold for the CPU. :D

hrmm
thanks for all the info guys,
ive started wanting all this now and i got a window kit and a neon light,lol and ill prolly be getting a thermometer soon and then ill get some coolers and then start overclocking, thanks again!:) :smoka:

So what you are saying is that you will rice up your computer.:D Don't forget to put up some sitckers with NOS-RAID or Vtec-ATA;)

yeah preety much:)

is there any special heaksink? I would like to see what this celeron can do, im going to get a bigger case and quite a few fans, but heaksink is a big ordeal so i was just wondering if anyone has any suggestions:confused: thanks

Bigger is better. Copper is better than aluminum. Fins are good. Thermal paste is also good (like Arctic Silver). If you look at some sites that are focused on cooling, you should get an idea.
Try the ViaArena forums for help also, there are lots of links and help here (http://forums.viaarena.com/categories.cfm?catid=26)

hmmmm... overclocking sounds fun.:D maybe i should try as well...but after i change my video card since it'z GeForce :( so....i'll w8 till i get a new video card. :D

I Really wish that people would read the dates of threads. :banghead:

anything that can potentially melt my cpu to my motherboard is not a risk worth takin imo

Overclocking will be gravy if it goes well, keeping all the components cool is necessary, but when you overclock you run all the components above design specification (although rebadging does happend, its normally not something we assume is done).

When running above the design specification your creating a higher error rate, although the faster clock may lead to quick repair of the error produce, but over a prolong period or a freak accident can actually cause data failure, which can spread across to ram and hard drives.

That's why critical pcs or servers aren't overclock simply for this reasons, basically overclocking is great but should only be done with caution and through lots of education of the goods and bad.

Im thinking of overclocking my athalon XP, even though it is a 2700, lol. Dont ask me why, i dont really know, by benchmarkign standards, its already extremely high. its running nice and cool right now with the stock amd heatsink and fan, around 40 degrees C, or about 100-105 degrees F. Thats just something im thinking of, dont know if i will.

I overclocked my XP2700, even though my copy seems to be a bit of bum.
I am currently running it at 2.36ghz (214mhz FSB, 11x multiplier). Its at 1.7volts. I can make it run at 2.47 with 1.775 volts. It will run at 2.58 with 1.85volts (the max my mobo allows), but, it crashes during benchmarks. If i could overvolt .25 more, i bet it would be stable. Oh well.
I am watercooled to, so, at 2.46, the max temp it reaches is about 35 celcius.
My video card (GeForceFX 5900) is running at 480 core, 1ghz memory (up from 400 core, 850 memory). That without any more AGP voltage, i could probably get 500 or 510 if i overvolted it a bit.
