Overclocking???



  Fiat Panda 100hp
Anyone here good at it?

I dont know how to go about overclocking my cpu, any pointers?
 
  Clio 172mk2
yer i used to do it along time back.

but if yer only using air cooling on the cpu dont bother , u`ll end up frying it

Best way is a full water cooled system , big rad with 3 fans , decent sized resoviour, good pump, cpu , mainboard and grfx cooler, also a timed relay so the pump stays going if the system is shut down , and maybe plenums for even more overclocking.

or through some dry ice in there should help ya

in simple buy better components instead :clown:

If you do a little research and be sensible then it can save you a ton of cash and it's a good laugh. The first chip I did was my celeron 300A which I ran at 450Mhz with the change of a couple of settings. It cost me £50 and was performing better than the fastest pentium at the time. That processor is still running in a machine to this very day! I've pretty much overclocked everything I've owned since, including my Athlon 1700+ (1.43Ghz) which ran at 2.4Ghz and cost £55. Again faster than anything AMD were selling at the time and since sold on and still working! Read around and see what the choice pick of the moment is, you will often find cheap low end processors that can be turned into power houses.

Get a decent heatsink, thermalright make good stuff. Make sure your case is properly ventilated. Get a good quality PSU (something I would recommend anyway). If you want long term stability use only small bumps in voltage. Test your setup properly with something like prime95, nothing worse than a twitchy machine.

Spot on, iv heard about these cpus and there the bee nees, therell take anuthin u chuck at them

^^ aye got an opty 148 @ 2.8ghz now. Not even fiddled with it properly yet, I reckon 3ghz is on the cards when I get some time! I also hear the cheaper dual core P4s are worth a look.

So guys what software do I need to get myself started ?

My picks would be prime 95 for stability testing, memtest86+, CPU-Z so you can see various clock speeds/voltages. Also some sort of temperature prog so you can see what the CPU is doing. Sometimes you get this with the motherboard. Failing that, some beers and a good session of counter strike to see if it crashes :clown:
 
You can overclock on air quite safely, especially if you upgrade your OEM HSF.

Presuming you have a decent mobo, it will have all the OC tools you need in the BIOS. Dont worry too much about 'frying' things. You'd need to be pretty careless to do that. Just take things slowly. OC in small steps and stress test at each stage using some kind of benchmarking software, while also monitoring core temperatures. If you're methodical, you'll see instability long before anhything actually 'fries'.

Worst case secnario is that it wont post after a tweak. Just make sure you know where your CMOS jumper is, or if it doesnt have one (some boards dont) then know the location of your battery so you can remove it and reset the CMOS. This will reset everything to factory default and it'll boot up no probs.

For small overclocks, you should be fine. If yo start getting more curious then you might need to start looking at memory dividers and locking the PCI slots etc. etc. It really depends on the specs and quality of your components.

Take it steady. Stress test at each stage. Monitor temps at each stage. Look for instability and when you reach it, throttle down a bit. Continue to monitor temps and continue to stress test.

Echo what Roy says

Usually if you do all the tweaking from the Bios, if you do something it doesnt like it usually doesnt even post when you first turn on, then you just clear CMOS and start again!

DEFO upgrade from the OEM HSF as Roy said. For now roy is the PC king for not for long ;)

It takes a while to fine tune it as such lots of testing to make sure the comp boots and usually best to go up in 5mhz increments until it wont boot into windows then relax timings on your memory and try again that dont work try a little more voltage you need to read up on it a bit as to do it properly can take you a good few hours.

I only did a quite overclock on my own system and then just could not be arsed messing with it its fast enough right now anyway so its left at stock speeds when it starts struggling a tad i'll think about knocking it up.
 
i wanna give this a go but... hmmmm.... dunno sounds like a long process, overclockin it a tiny bit, then bootin and benchmarkin n checkin temps and that.

Are there any sites about it, rather then forums, hate routing through forums for stuff -_-

Patience is the key in overclocking. Got my Pc from 2.0ghz to 2.5ghz without much of a prob. It can do 2.8/2.9 but need different ram as my ram has got tight timings, doenst like high fsb etc

Ok thanks guys, I have prime95, cpuz and speedfan which tells me the temp of the cpu. Could you enlighten me to which settings I have to tweak in the BIOS?

Many thanks.

Ahh...thats why the good Abit mobo have a clear Cmos button on the front controller. We had one of these in at work last week to see what was wrong. And wondered what the 'Special' button was for. Must be a bloody good overclocking board

Ive been using this site and I've just joined. It seems pretty good and you'll find a whole heap of stuff about overclocking virtually everything. For sure you need to spend a lot of time reading and asking questions, but then if you are not prepared to do that, then overclocking aint your bag - there's no easy route :)

The main seeting you need to overclock is FSB, HTT and Voltage. Adjusting the ram speeds are good too. if you have a cpu/motherboard which slows itself down when it gets hot you need to turn off the throttling, which is usually in the bios settings. Best thing to do tho is to read up as much as you can on overclocking and try and understand what everying does so you know what your doing more and what to do when things go wrong

So change the timings on the ram.

Cant you divide the memory bus speed though? (in response to Adam)

yes i can, and infact i just tried it and it still doesn't boot when i get higher up the fsb clock speed range, but i have been monitoring the temp and i think it might just be down to a crappy cpu heatsink.
 
  Clio 172mk2
the problem uve got is the old processers used to run at low temps, so u could over clock them more safely on air heat sinks, but cpu companys got wise to this and made them so they now yer allready pushing the chip a bit farer then normal , so it becomes harder as the heats there from standard speed, yes there might be the odd chip with the ability to overclock on air. me personally it aint worth the effort , cos one slip up means u`ll be looking at new hardware.

And for what gains u`ll see on most modern chips , is it worth been a few secs quicker . prolly see better speed gains by installing a fresh version of windows

I can't change them anymore as the computer goes unstable. Think my ram doesn't go over 250fsb or something

Use a divider then. That's what Wozza meant.
 
  Monaro VXR
No i meant drop the ram down to cas 3 or something depending on memory you have give the ram a bit more voltage or you can use a divider.

Well im on 2.6ghz now - gotta test it, make sure its stable etc before pushing it further again. Gonna get a dual core cpu soon anyway :)

Edit - I have gone back to 2.5ghz now as 2.6ghz is unstable. I think I have reached the limit on my ram, used divider and all sorts but my system tools i am using say's the cpu is unstable pretty much straight away :/ Wish I had some Mushkin Redline ram

Not even bothere overclocking my X2 yet mainly cause i just can not be arsed plus not using it for gaming as much now so makes little difference.
