Overclocking with AMD 64

hey guys, ive heard that that atlon 64 overclocks a bit diffrently than the other CPU's out there, and because of this i need some help figureing it out, the tutorials always talk about FSB Memory clock speed, and CPU clock speed, but i plu see the CPU clock speed. ive raised the Clock speed to about 222Mhz and it runs at 2Ghz but i know i can get it better than this. what would i need to do to go beyond this point. at this point it fails to start windows, and even now occasionally it will restart the computer on its own will, usually when i do something CPU intesive. thanks guys
 
Unfortunately not all processors are created equal. You're 3000+ isn't necessarially going to oc as well as someone elses unfortunately. There's just no standard set as to how far a chip with oc. Especially concidering it's not actually intended to go any further.
There's 4 major factors at work here. First off, you're cpu. This is an easy one as I'm assuming it's a new processor and therefore has a Venice core. That's good as those generally have some good OC potential. Then there's you're ram, if it's cheapo no name bargin ram it's not going to give you very good yeilds oftentimes. Then the motherboard. I don't see that being a problem MSI makes decent boards and the nForce 4 line is concidered a decent overclocking platform. Cooling comes in as the most important factor here. Again I'm not really seeing a problem, that's a minor overclock and even the stock heatsink/fan is plenty to keep it in the 30's. If you are for some odd reason seeing cpu and system temperatures in the 60's then you might have a problem but otherwise cooling is not a factor either.
What it comes down to is you might just have a cpu that doesn't oc very well. It's not unheard of by any means. There's no reason to increase the voltage really that I can see. Maybe a more experienced overclocker can shed some light here?

i wudnt reccomend increasing voltage becoz over time long term damage will be caused and the cpu's life is shortened.
 
Make sure you're overclocking correctly, but to me it sounds like your problem is in your RAM. Post a little more info on that, run MemTest and SiSoftware Sandra 2007

These days this isn't so much a problem. AMD, Intel, and motherboard manufacturers have done a good job in improving the materials that they build their chipsets with. I think they coat them in some kind of heat-resistant plastic, or material of the sort. Anyhow, unless your temperature is above 50 degrees it will not damage the chip. The real temperatures to worry about are the upper 50s and into the 60s, but most processors have a cut-off point that will shut yoru computer down if it gets to hot (and not allow a reboot until it has cooled off considerably).

I was just laughing because your response reminds me of someone who sells processors and doesn't want people to overclock. "You have a 2.4.. if you want to get to a 2.7 you have to pump more vol7age into it and that can destroy your board and cpu, but i can sell you one for $300 more"

The truth is people (enthusiasts/gamers) have increased the turnover rate of upgrading their hardware. Some go as far as to alway buy what's new (the extreme wealthy enthusiasts) - others upgrade every 2 to 3 years. What does this mean? Good you should ask.. even if the vol7age "did" have limit the lifetime of the cpu (however long that limit should be), it will more than likely be way after the time they decide to buy a whole new system.
 
I would also like to know how to overclock an AMD 64. I have done some reading about it and I get confused with all the FSB:DRAM ratios, HTT multipliers etc... Any help on this?

Northwood pentium 4s are rated at 1.5v but the intel datasheet gives a max voltage of 1.75v! To be honest I wouldnt like to crank mine up to 1.75v for the long term (I did do a voltage mod once to see if I could get a stable 33% OC but it wasnt stable) but Ive had it at 1.6v (1.65v in software readings) for years. No degradation, nothing.
 
ok i have sisandra 2007 and i dont know what test to run to figure out the RAM details, but i can tell you that i have one PNY "OPTIMA MEMORY" nd one Corsair stick, both at 512, for Si sandra all the info as of now i could find was this...

theres that lol
 
They are some deadly chassis fans you've got. You could make a helicopter out of them! :)
 
haha what do u mean? my fans can be set to run at a controlled speed in the BIOS but it makes a stupid hummmm and i just let it run at full speed
 
90,000rpm for your chassis fan and 45,000rpm for your cpu fan.
Even if they were 9,000 and 4,500 rpm they would be faster than everyone elses.
Sandra has got it wrong.

As far as im aware you need a resistor if your not running an electric motor at full speed. I dont know where that might be on a motherboard so you are probably best off running it at full whack anyway.
 
can anyone help me with my overclocking problem?? i cant seem to get it stable at 2Ghz by just changing the Mhz speed to 222, i even tried to lower it but it still shut down. can ANYONE help me?
 
Well i googled overcloking AMD 64, and found a lot of guides and stuff. For starters you should read this, i think it is explained decently (i've yet to overclock) i'm going to keep reading up on it so that i know what i'm doing before i start OCing. Try reading this to see if you missed anything.
 
ok, i dunno if this will help becouse i have a different motherboard and cpu to you, my cpu is a 3700+ amd 64, stock is at 2.2ghz and my overclock is at 2.8ghz, i am using the stock cooler, and a voltage bump from 1.40v to 1.47v was needed, now i dont think its the actual voltage that kills your cpu and mobo if you have a decent mobo, but its the temperature caused by the voltage increase, usually it shouldent matter if you have crap memory, my memory is just 2x 512mb or 1x 512mb generic crap, and all i do is lower the cpu to memory or fsb to memory ratio, cant remember which one it is, so at the moment, my memory is running at 420mhz, 20mhz over its normal speed, any further and i think it would be really bad for my memory, but i also had to lower the HT multiplyer setting in bios to 3x, any higher and the comp would freeze on bios becouse HT was going over 2ghz, as this is how the HT speed is determind i belive, FSB x HT multplyer x 2, and in my case it was, 254 x 3 x 2 which equals 1524mhz, to increase the cpu clock, you increase the FSB clock, but doing this also causes the memory to increase, thats why you gotta change the cpu to memory ratio or fsb to memory ratio, cant remember which one it is, but there are preset ratios, i either had mine at 420mhz or 333mhz i belive, nextr i had to change the voltage to 1.47v, i first tried 1.42v then 1.45v, 1.45v was ok but after long periods caused shutdown, i tried to get to 3ghz, i manged to get into windows, but it did not work in games, i had the voltage at 1.6v, NEVER go above 1.5v i say.

The above is just really the steps i took to overclock, not somthing you should do exatly, i dont know if its even possible for you, as you motherboard is different, so maybe the overclocking options might be better, i am running on an Nforce 3 250gb mobo, from gigabyte, i think my cpu overclocked well to say that gigabyte aint aiming at overclocking boards.

Also, my temperatures with my overclock were 29-30 idle and 39-42 load, the reading were took in winter tho.

I hope some of this helps, just thought i would tell you how i oveclocked mine, might provide you with some usefull info :)
