Mainboard OC Failure

Hello. I have a problem with overclocking. My mainboard is MSI 945P Platinum. When I try to overclock it to more than 3.3 GHz, it doesn't start and even there's no beeping. What can I do with it? --- What I've done: updated bios, tried to change ram timings but there was the problem that it didn't start and there was continuous beeping, so now I have it By SPD, installed latest chipset drivers, changed memory freq. to the lower one, but nothing from this worked for me. Processor: Intel Pentium 4 3.0 GHz, Prescott RAM: A-DATA 2x512MB 333 MHz DDRII I am not sure if this is caused by my RAM or mainboard, but I guess it's by mainboard.

    After your reply, I tried to do these things you posted, but nothing from this worked. I tried to low the ram freq., but when I did it, my PC didn't start, so I had to keep it. The next thing was the voltages, I set it higher but it didn't work also. I think it isn't caused by cooling because the computer would start although it hadn't got any cooling.
    Maybe I am maxing out the power supply, but I don't want to invest if I am not sure what it is caused by. I cannot lower the multiplier because it is a fixed number that I can't change (15).
    What can I do to find out what it is caused by?

    So, which RAM do you think will be a great investment?
    Apacer DDR2 2x 1GB 800MHz GOLDEN KIT
    or A-DATA DDR2 2x 1GB 800+MHz dual Extreme Edition
    or CORSAIR DDR2 2x1024MB 800MHz TWIN2X

    I've just found out that my motherboard doesn't support 800MHz RAMs, it supports just 667/533/400. But I have 667MHz so I don't know where the problem can be. I tried to low the frequency and to high the FSB, but it didn't work. Maybe there's the problem that my power supply cannot handle it. I have 400W. I will focus on this.

  • Theruby Oct 07, 2007

    Just wanted to ask if the power supply cannot handle it, how can I recognize it? When I set the frequency too high, my PC starts, but monitor is black and there's no beeping. May this be caused by power supply? (I mean if the PC can behave like this if it's caused by power supply)

What I've seen, and this is just an example, but some guys will be given a low board, and then to save money but try to get more bang for nothing since it was a given board, is they will start putting on all this high end stuff trying to make a sow's ear into a silk purse, you know what I mean. And I'm not saying the guy is to cheap to go buy a system than has the capacity to handle what he wants to do with it to begin with, he's just trying to see what he can get away with because he's starting out with a free board that leaves alot he can spend money on. And I have gotten this "bug" myself so I don't have any room to talk, but then the guy will try to put a GX9800 video card, two hdd's, corsair 2 gig mem. sticks, and then try and push this Pentium II board with a 450 MHz cpu, and I'm going to make a joke here, but he'll try to push this poor cpu to 2 gigs. Then he encounters all kinds of problems, i.e. shut downs, blue screens, beeps, no start ups, etc. and then I see him writing in help me sites as to what could be causing all the problems. I have to laugh. And I certainly am not trying to be demeaning to a person with a genuine problem. But, sometimes people get excited and think their computer is supposed to create life and when it doesn't they're disappointed. What I've learned the hard way is what you don't know can fry boards, psu's, cpu's, and generally cause alot of unnecessary havoc. What they have to do has to be backed up with many hours of "study" so that they can make an "educated" guess as to what it is they want, and more importantly, what they want it to do. Alot more fun can come from a good strong board, and take alot more abuse if they start out with a good foundation for all the other junk that will be hanging off the thing. My next door neighbor had a system built up so powerful that he had his garden hose plugged into a automotive pump rigged up over the cpu to keep it cool. NOW THAT'S EXTREME! But, it took it and he gamed his brains out for days on end.

Odds are it's a combination of things. Any of the things listed below are most likely adding to your crashing -You're ram is probably operating at it's max threshold. -You may not have good enough cooling on the processor / ram. -Your processor may need higher voltage to handle that large an increase in clock speed -You ram also may need an increase in voltage -Both of those above are dangerous btw -Your motherboards south bridge may not be able to handle that much power -depending on the specs of your system you may be maxing out your power supply -you may be running too high of a fsb for the ram / motherboard to handle -You may need to lower the multiplier to raise the fsb more or vice versa First and formost though, cooling and voltage are going to be the key in extreme overclocking, which is what you are doing by raising the clock so much. You need to read up on voltages related to overclocking the processor and ram and become an expert on the subject. Only once you understand the reasons why it works and how dangerous it can be to your hardware should to go any further. You also need to keep in mind your cooling setup. FSB overclocking overclockes all the of the other parts of the system too, not just the CPU, so multiple cooling fans that eliminate dead zones and target certain parts are a must. Make sure your processors heatink and fan are more than ok, in fact, you may want to consider some type or liquid, cryo, or heatpipe technology if you aren't already using them. Like I said, you may need a larger power supply too, or maybe some stronger ram. You could try raising the rams cas latency. raising it by .5 may make the system bootable, or even stable. But this also will slow down the system, so you have to way to pros and cons and see how much higher you can go and if it's worth losing ram latency. 300mhz is a pretty large overclock, personally I'd be happy with that unless I was ready to invest in the parts and time needed to push the system past a 10% overclock. Remember though, as good as an overclock you get on the system you still need a software tune as well. Even the fastest systems can get bogged down by an untuned windows. If you're not already, learn everything there is to know about tuning windows services and explorer.exe as well as registry tweaks. You can literally cut a windows install down to half of the ram footprint as a default install and make it use very little processing power on the backend. If you have any further questions post them here and I will do my best to reply back. I hope this has explained your question in detail. If I've helped you please don't forget to rate me. Peter

    If you're not changing the multiplier due to it being locked then you're just fsb overclocking. That is your problem. You're maxing out either your ram, or your motherboard. Odds are you need overclocking specific ram. They make ram that is capable of running higher than industry standard speeds, you'll need that to make any more progress probably.

    Personally I'd be pretty happy with a 300mhz increase, thats 10% when you get down to crunching numbers. Some people only manage 5% overclocks.

    Like I said, to get any further with this overclock you need to make investements. Better ram would be my first suggestion, then maybe a better power supply after. Something in the 500 - 600watt range will do just fine.

    I would probably go with the corsair

Hello here is the msi homepage:

You have to be sure its the right mainboard.
Flashing the bios with a wrong one will destroy the mainboard.
It does not have to be a bios problem you have.
The problem could be a faulty power supply, or a bad ram module.
Or simply the pc is shutting down, because of overheating/overclocking.
If you get the blue sreen of death, the harddrive could be the fault.
Try also to renew the cooling paste, between the cpu and the cooling element.
Clean also for dust.
It sometime will help to upgrade the bios, when the pc is unstable.
But do fix the power shutdown problem first.
If you upgrade the bios, and the the pc is shutting down while doing this, the mainboard is scrap.

Best of luck

HI, i have the gigabyte MB GA-945P-S3- and i saw in GIGABYTE web site that i can go with C2D E8400 but with overclocking and saw awhile ago that there are another problem with the CPU MP in the bios of it...

Only the Gigabyte GA-945P-S3 revision 3.3 does allow C2D E8400 or C2D E7500.
However the C2D E8400 only by overclocking, which certainly is not recommended.

So the Gigabyte GA-945P-S3 mainboard revision 3.3, should work with the C2D E7500
with BIOS version FFd and FSB setting at 1066 MHz.

I am looking to download an audio controller for 7236

I've got a GF615M-P33 mainboard 3.0 ghz which have overclocked to 3.5ghz, i've put an nvidia GT9400 1gb, the problem i've is when i play certain games after 2-5 mins my monitor shuts down & computer...

Hey! i have the same problem with MSI GF615M-P33 with Inno3d GT240 Video card and 600W power supply. When i play games like left4dead, call of duty or even counter strike after 2-10 mins my monitor shuts down & computer freezes too. I don't overclock!!! and recently updated the chipset driver (, problem still persist.

Overclocking failure!!!

Pull your cooler off the processor and clean off the thermal paste and reapply. Seriously think about putting some bucks into a better way of cooling that monster if you are going to be overclocking. 185 degrees is pretty warm, you probably just baked the thermal paste, replacing it will get the cooling effects back in place.

Mainboard of PB6200

Hi, I'm looking for a mainboard too. Just last week one of the PLL clock multipliers wacked-out and overclocked one of the DLP ICs. (confirmed by O-scope and service manual). Guess they timed the warranty just right before the units start to die.

Overlocked my Intel Pentium 4 3.00 Ghz

You have to go into your bios and see what your front side bus and memmory speeds are. If you overclock you cpu, sometimes you need to underclock your memmory. Say step your memmory down to 333mhz and overclock your front side bus(fsb).
Normally your fsb is 200 and only increase it by mhz. Restart, go into windows. and see if it is stable.

I always use cpu-z and gpu-z to check all of my hardware settings. I use ati tool to overclock my x1950 and it is great. There really isnt any good cpu overclocking tools because its better to do it in the bios.

Do a specific search in google for your processor and overclocking.

I tried to overclock it

Doesnt sound good - When you said you reset the bios that meant you reset the CMOS jumper on the mainboard?

If that doesnt do it then i would try just one stick of ram at a time.

You may even have burned up the CPU trying to overclock it so far. If you could find another athlon xp then i would try that last.

If that isnt practical then it is likely the mainboard is shot.

It would probably be best at that point to use this as an excuse to upgrade to a newer platform - an athlon x2 5600 with mainboard and RAM is only about $200-$250 depending on the combo you get. Keep in mind most newer boards will use PCI Express instead of AGP video cards.
