hello,
being an absolute noob when it comes to overcloking i dont really know what im talking about.basically i overcloked my athlon 64 3000(venice) from 1.8ghz
(clock speed, run speed i duno) to 2.1ghz(i think) then in a daring attempt i tryed to push it further (in bios puttin my external clock from 230 to 240 and PCIE clock from 115 to 120.) windows then didnt boot (which happend about 20mins before) but this time was different. Now when i try and boot i get, Sytstem is running in Fail-Safe state. Please recheck -BIOS CMOS SEtup.
this is a problem which i have and fixed before by loading optimized defaults, didnt work this time. So i press F1 to continue and i get -
DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER.
am i right in saying windows wants me to re-install itself?
PLEEEASE COULD YOU HELP, i would appreciate any sort of help at all.

Have i oc'd too far?
 
Unless you have very good cooling such as water cooling, limit OC to 10%. Most damage comes from heat.

CMOS error is a BIOS problem - since reload default failed, download new BIOS plus install tools and try a BIOS flash (MB site will have intructions).

Once flashed see if the BIOD detects your boot hard drive - as boot disk fail means the pc can't see your hard disk.

Good luck.
 
Did you try clearing the BIOS?
I think you would have to flash the bios. Take the official ones from the site.

Good luck..!

BS.

1. You can OC really high on air without doing any damage. I've OCed my AMD 64 50% on stock cooling.

2. Heat don't kill, voltage do.

BS again.

He doesn't need to download a new BIOS. He only got a message that since the current BIOS settings didn't work fail safe mode was enabled.
 
ok it seems to be working now. i just left it and tried the next day and it booted fine. but now i have (very slowly) got it running to 1.98ghz and acording to "motherboard monitor" the temps are 27, and 35 degrees. should i keep going and maybe get it to a 2.2ghz or is there really no point?
 
What motherboard and memory do you have?

My 3000+ Venice is running at 2.7GHz at stock cooling. You could probably reach somewhere between 2.5-2.7GHz.

The imporant things to change in the BIOS to get a good OC:

CPU clock
HT Frequency
Memory divider
CPU voltage

- Heat? do you have any idea how hot an Intel prescott runs compared to the AMD Venice core?

Damage is done with heat but its the extra VCore producing the heat and damaging the die.

There is no diffrence between two models with the same core, only the multiplier resulting in a higher clock speed (and maybe die quality) - overclocking half the time is not overclocking, just makes a cheaper cpu run at the speed of the more expensive one.

hey i have an Abit AN8 mobo with GeIL 1GB (2x512MB) PC3200 Value Dual Channel Kit CAS2.5 ram. my current temp is around 30 degrees and cpu is running and 1.98
 
I would just like to add that throwing a cooler on a cpu that is perfectly capable of freezing a mammoth is NOT good for it. CPUs are designed to run at the temperatures they do, so when you overclock, don't cool your cpu down lower than the temperature it normally runs at. You can get a modest cpu to run blindingly fast on just stock cooling and an extra fan somewhere else in the case. Just like the_guru says. And that is pretty impressive, i leave my CPU alone though, it was too expensive for me to be messing with any time soon.

Bah there not designed thermally, the HSFs are designed to cool down cpus at best as posible at a cheap price (eg slow/budget models might not have copper cooling), hotter cpus get bigger (more efficent) HSFs and when you overclock you get a bigger HSF to take care of the excess heat and keep temps lower (idle, load, max).

The biggest HSF posible installed on a cpu would only lower the temps at best to room temps (20 - 30c) and that would do the cpu better then sitting at 40 - 50c all its life.

Behold the Intel Prescott - im sure they designed it to run hot, its idle temp is something half the A64s will never see, if you want to overclock it its a bare minimum to get a huge cooler or water cooling.

May i ask what cpu you own?
 
AMD 64 3500+ 939 Socket

IF something is designed to run at say 72 degrees it was obviously designed to run AT 72 DEGREES, so why run it at a temperature it was NOT designed to run at? (72 is just an example) I have not checked my cpu temperature even once since i bought it. Take a look at a CPU chart next time you think buying an intel is a good idea. You can modify your stuff all you want but the bottom line is, if you run something too cool resitance increases and therefore voltages will be effected, so when you have your cpu at -5 celcius id like to see it go more than a second without an error. I personnaly won't put a heavy piece of copper directly above my graphics card, you say they make computer parts out of cheap material but you trust the motherboard's fan mounting enough to allow it to balance a brick of your nice EXPENSIVE graphics card. But then again each to his own, I can't stop you and if you are used to your setup then do what you want, this is not a flame, you disagree with me and i disagree with you, that is unlikely to change so God speed to your efforts.
 
Flame? nah this aint no flame - its pathetic.

Go onto google and type in "cpu too cold" and see what you see.

As for any big HSF's falling off and damaging components - most large hsf's dont use the original mounting bracket and are bolted directly to the board with its own retention bracket.

Colder the better, the only issue with say LN2 or DryIce (and the others) is condensation. What if i live in Antarctica - so now i cant use my cpu cause its "too cold"? Yeah pull the other one out. To my knolodge with overclocking - the colder the more stable and less vcore required.

As for Intels and the THG charts - did i say i like/want an Intel (currently)? There freaking hot and when you overclock with stock cooling you wont get far where as water cooling or better will see 80% of em hit over 4ghz.

CPUs are fine when they are o/ced as long as they don't go too high above its stock temp... if system won't boot or windows isnt stable add vcore, but it will also add heat.

A64 Venice cores are very overclockable I myself o/ced my A64 3000+ from 2ghz to 2.6ghz stable with temps not exceeding 45C+/- on my stock HSF.. and also a very helpful yet cheap duct mod

I hate to tell you this, but you are way off; cooling something down actually decreases the resistance. The cooling systems on the market today have not in anyway been shown to damage the CPU. I have never read, heard, or seen a CPU that was damaged because it was run too cold. I have heard of countless CPUs that were damaged by heat.

You wouldnt' happened to have taken any physics classes would you?
HOTTER MATERIAL
LARGER SPACE BETWEEN MOLECULES
MORE ENERGY PER ELECTRON
LESS RESITANCE.

TEXT BOOK
FACT
LAW OF PHYSICS

Let me guess, you are one of those americans who thought that germany was one of the allies in ww2, right? ~40% of american children believed this.

The hotter any material gets, the more atomic motion is generated. More atomic motion means it's more difficult for electrons to move through that material. Think of it as crossing a busy freeway - is it easier to cross when the cars are going 5mph (cold) or 100mph (hot)?

With your logic, why would we use cpu coolers at all? You're saying they should get more efficient as their temperature rises...that's just retarded.

Yes, I took many physics classes...as well as chemistry, engineering and material science...all of which say YOU'RE WRONG.

If his logic was true compaines such as asetek or extreme cooling tech. wouldn't exist. As they use a extreme cooling liquids and specially made evaporators.
Have you never heard of
VapoChill lightspeed? or Prometeia Mach II Gt

Mach II Cooling Specs:
Cooling Performance: -65C at 0W/-30C at 200W

Vapochill Lightspeed Specs:
Cooling performance load/idle 200W @ -25,5'C / 0W @ -48'C
 
And if you haven't read any of the articles in TH on cooling... well this here 5ghz p4 and Liquid Nitrogen @ -190C should put some re-thought into your philosophy...

Are you addressing me? I agree with you...you kind of just restated what I said.
 
you can cool cpus very very very cold (-190 on ln2 -50 on phase change), so no, decreasing temps are not increasing resistance.

mind you, intels cpus are only rated for 5c, colder then that its no longer garunteed to work
 
I wasn't exactly addressing you i was quoting you because i agree with you.

As for Intel CPU's having a limit of 5C not true considering in that THG link it's an intel CPU running at -190C....
 
no i was saying intel only rates their cpus down to 5c. it is not garunteed to work, and the warranty is null and void.
mind you, if you are cooling it that low the warranty is sure to be voided another way (oc)

Allright you win, just checked giancoli. Sorry for flipping out i'm kind of pmsing due to the topic i made about being rather angry. And cooling companies only exist to stop your cpu fusing due to heat, even if what i said were true the companies would still exist to stop your stuff blwong up in your face.

😱strich egg on face:

BUT TAKE A LOOK AT THIS IDIOTS

http://www.uel.co.jp/ptc/ptc-graph-01.htm

notice how the lower you go RESITANCE INCREASES, oh you stupid stupid people. IOW YOU ARE RUNNING YOU STUPID COMPUTER BELOW 200C arent you? therfore you are increasing resisantce just as i said you would.

'tard

VICTORY IS JUST SO SWEET.
