Overclocking concerns - Please Help

Just have few concerns that I want to clarify before doing more overclocking to my processor. I have a prescott 3.0GHz processor. I have overclocked it to 3.52Ghz without changing any other values. Temp is OK and my computer is stable. I however wanna check the max OC limit on this processor. How far can I go??

According to info I got online. I am going to:
Keep adding 5 -10 MHz until my computer becomes unstable.
Then I up a notch on the vcore (add increments of 0.025V for a max of 3 times)
If the computer becomes stable - should I stop here or can go back and add 5 to 10 more to my speed for processor and then continue again with adding vcore voltage.

One thing I noticed, I OC my processor by 500Mhz (from 3.00GHz to 3.5Ghz) and my temp did not even increase. That kinda concerns me if I did really overclock the processor. When I right click "My Computer" and also in BIOS it does say 3.5Ghz. Please clarify

Thanks again for your help.

howd u overclock? in bios or in windows? where are u getting temp values from? mobo sensor or a third party add on sensor? I noticed u still have the stock heatsink on it in the pictures and u have a prescott. One of the things that might affect your value of temp is the basis of temp management from within the proc. It might be getting extremly hot and throttling itself down to stay cool under that stock hsf. Id suggest this for a hsf http://www.zipzoomfly.com/jsp/Produc...uctCode=373035 Any more q's post or pm me. Either way Ive got same mobo and a p4 ee all overclocked.

My temp readings are at 56*C and has remained the same after 500MGz of OC.

My questions is should there be a increase in the temp if you overclock or does it just depend on situations. You said you have the same processor, have you OC'd and how far have you gone.

I said same mobo. I made sure I stuck with a northwood core in order to keep my temperatures with air cooling in control and be able to overclock highly. With a 2.6 I ended up running 3.2 24/7 but I got it up to 3.6-3.7 for benchmarking. The 3.4 extreme edition I have now I got to 3.7 but keep around 3.6 for 24/7 use. You didnt say exactly if you are overclocking via a prog in windows or if ur booting to bios. I will assume windows which in my opinion it may not be overclocking at all but just tricking the os. Seen it happen many times. Best bet is to mess with the front side bus in the bios. Make sure however the divider value for the ram is right so that the speed of the ram against the increased speed of the bus keeps the ram within the limits of stock or little higher depending on voltage that you use to it. Also make sure you have the newest bios. Now as I said before I'm willing to bet whats happening is either ur cpu isnt actually being overclocked or its throttling itself but u dont have a prog to detect the throttling.

As mentioned in my previous post, I did the OC by changing the FSB in BIOS. I did not use windows because I dont trust those programs. The RAM CPU speed is set to 1:1 and my vcore values are within limits. I guess I am going to a step ahead and see if I can do a 200MHz additional of OC.

run this prog at normal speed then at overclocked speed specifically paying attention to 1m time value. http://files.extremeoverclocking.com/file.php?f=36

I'd suggest using this as a monitoring program for our motherboards as it seems to support it the best http://downloads.guru3d.com/download.php?det=204

to check throttling try throttlewatch http://www.majorgeeks.com/download4431.html

then test ram and cpu burn in give sisandra suite a go. http://www.overclockersclub.com/down...ion=file&id=12

For more burn in http://www.mersenne.org/freesoft.htm prime it.


using all those progs together can give u a sense of how your comp is reacting to the overclocking. the superpi will show cpu as well as tight ram latency benefits, motherboard monitor 5 as I said is best for our boards of all progs that ive seen, throttlewatch will tell u if ur cpu is throttling down, the sandra suite will allow u to run loop after loop to make sure it is stable, as well as running prime to make sure its prime stable for 12 hrs or more would be best. gl.

And I didn't know if u had overclocked in bios because u said

that you had looked after checking in windows.

Sorry about the confusion, but this is where I mentioned that I did it in BIOS. Anyway, thanks a lot for all those links, I am going to download all of those and probably get a feeling of my OC situation.

-I have heard about "overclocking". I've heard of people overclocking their video cards too. Can someone please explain this to me, and maybe tell me what is being done by "overclocking"? And how to do it?

Thanks,

You have to know everything involved with overclocking. Overclock too much and you fry the hardware. Overclocking (OC) is just kinda pushing the speed of the hardware than its recommended speed. I have a 3.00 GHz processor and I have OCd it to 3.59Ghz, thats adding about 600MHz more speed. Things you have to look out is the processor temp and the voltage.

Anyway I overclocked to 3.59GHz without any problem. Increased the vcore by 0.025 and the d-ram by .05. Computer is stable and my processor is running at 61*C. I think, I might drop the idea of water cooling since 61* is OK and I cannot go any further with OC.

If I go 3.6 GHz, I get a SATA BIOS error message - "Cannot write to offset 44h !". Whatever the hell that means. But I am glad that I could OC to about 600 MHz.

By the way anybody know what this error message means. Is there a way to fix that error message so I can go further with the OC. Thanks for all your help.

There is a lot to be said about overclocking in general.

My philosophy is to get an excellent motherboard then get a rather cheap cpu and get it running to its maximum. High end cpus always come at a high premium. I've been doing it for about 8 years now. I change systems about every 2,5 years to somewhat stay current.

It has involved a lot of reading to know which motherboards are best for overclocking and which cpu to use with the motherboard. Anand Tech has a few forums with oc enthusiasts http://www.anandtech.com/ and would be a good place to start. You should find there what you need.

I also need to say that overclocking has its limits and often requires a better heatsink and fan to keep the cpu cool and that the life of your cpu may be shortened. Otoh I think that if one uses a cheap cpu and gets the performance of another cpu costing twice or more, the benefits are worth it. The life expectancy also depends on how much you use your cpu. I was part of a team working on [email protected] and my cpu was working 100% capacity for nearly all nights for over a year before stepping down with 3k results in my name. I'll be due for a new system around April or so and will look for another system that I'll be able to overclock again.

kumiyer, increase the amount of voltage to all of the options it gives u... that should let u overclock it even more.. i love overclocking AMD's better though :-)
Um, the "cannot write to offset 44h" MIGHT be a hardware buffer, to maybe protect the cpu from overclocking tooo much... 44h? hm.. hope this helps..

I have AGP/PCI at 66/33. I cannot go over 3.6 due to heat issues and hardware conflicts, but I have recently bought a water cooling system. WIll let you guys know how it goes.
