Overclock Testing

So I've had my system OC'd to 2.20 Ghz for a while now, though I never really tested it. My stsrem seems to freeze and blue screen every so often. I'd like to test my OC on my CPU.

when using Prime95 to test my system:

1: What mode should I be using to test?

2: What am I supposed to be looking for in the test?
 
i get that blue screen when i overclock too what test do u use there are like four of them.
i do the first one and the gives me the blue screen

I've been running the second test for a little over an hour and everything seems okay. I just wasn't sure which one I should run. I just switched to the first one.

So a BSOD is what I'm looking for in a unstable OC? Or for the system to freeze?

eh 24 hours is too much, i overclocked my 5200+ at 3ghz, i monitored my temps, and there is a point where the temp will not go any higher, and i even tested it for 4 hours, and it didnt go any higher after 45 minutes... So 24 hours=overkill imo.

Well I ran the first one for an hour and haven't gotten anything higher than 56 degrees and it hasn't crashed. Maybe I'll start inching up a little higher :)
 
I would say keep going, cuase the amount of power that your computer is using is un-realistic, i have never had a program that has my cpu run at 100% for a period of time, not even games are close to requiring that.

keep going man, slowly tho :D:good:
EDIT: thats a pretty decent temp, with the overclock i get now i get up to 63c, so i would say if you get up to 60c stop.(im not sur what the max temp for yours is, im sure its around 70c, but check it out for yourself.)

60 is fine for a load temp, i would say stop it at 65. odds are it would only ever get to that temperature while doing some hard encoding or editing, and only stay that hot briefly. gaming won't do it.

It all depends on how important the work you a are doing on your computer is to you. If you do nothing but surf the internet and play games, where a BSOD is more of a bother and an annoyance than anything else, 4 hours should get you in the right direction.

I have perosnally had my OC fail at 8.5 hours on small fft... one more notch up on the NB voltage led me to 24hr stable. It would suck if you are in the middle of something very important and your rig blue screens. Just my .02
 
One more quick question: When does it become necessary to change the voltage of the CPU?
 
when your system is not stable, it will require you too feed more power to your cpu, but make sure that you watch your temps, cause it can raise pretty fast..

not necessarily mx344.

let's say that you have a stock CPU that you are just starting to OC. You keep the voltages stock for now. You manage to raise it by 0.6GHz, then your system starts freezeing and bsoding. If you raise the voltages it may allow you to get a stable system and maybe even go further, but sometimes, that may be the limit of the chip.

Also, changeing the memory timings and/or voltages can make the system stable without touching the CPU voltages.

It is the end of the line route to getting your system stable/further overclocks basicaly, so yea, you were 99% right mx, but not totally :P

As he asid though too, it can change your temps hugely, so you will want to watch it if you have to up the voltage at all

I'm unsure as to memory timings and voltages. I've got two different brands of memory (OCZ with a heatshield and Kingston without, but all is PC3200).

I had it at 2.32 Ghz and ran Prime95 and it errored after 11 minutes. I throttled down to 2.30 and it errored a little over an hour into. The system seems to run and game fine with it at that speed, but I want the fastest I can get. What should I do now?

EDIT: Here is a link to some pics of my frequency/voltage control in the BIOS

No but it's for longterm stability, the longer it goes without error the more stable it will be, you can error out after just a minute or two so it's not always heat

Im not farmiliar with DDR ram, but i think this rule applies to all ram, when overclocking, you are going to want to lower you mhz on the ram, maybe the timings but i do the mhz first, e.g. if you have 800mhz ram(ddr2) then youll want to put it down to 667mhz, so you can achieve a better clock.

I don't want to mess with anything without a little more advice.

Here is an album of everything to do with memory timings:

Nevermind the memory remapping. I have to turn that to "on" so I can see at least 2.75GB out of my 3.

I have 800MHz and managed to get from 2.66GHz stock to 3.8GHz by dropping to 775 MHz, you don't have to go a full load down, just a few MHz can often do the job.

voyager, do you have an option to change the memory frequency, if so, that is the one that you want, drop it a little.

Also, before you do, open up CPU-z and look at what voltage your memory is at and knock it up a little, very often when overclocking your CPU gets more power, but your memory gets the same as before, even though it is having to do more work because it is throwing information at the cpu and taking information from it more than it was before the OC

=EDIT=

should say, if you do raise the temps, be careful, do it and after a few minutes and a stress test, pop the side off of your system and put your fingers on/near the memory and feel if it is hot, often when you raise the memory voltage it can cause a fairly significant raise in the heat, which can be bad news if you don't have decent head spreaders and air flow on your memory and in your system
