Graphics Card not working after overclocking CPU

post #1 of 9
Thread Starter 
Hi, i'm a bit new at overclocking & I tryed a few differnt OC's on my ASUS Rampage 3 Extreme mobo with a i7 950
& the first two worked ok @ around 4.0 GHz but the 3rd time i tryed i chaned the memory timing & got no post beep & the graphics card/9800GX2 died/no display,i reset the cmos & i'm using a different card now & its ok, but if i put that same card back in it will not boot. Note: the 9800GX2 is working as i tested it in another comp.

Any help would be much appreciated.

You can pull the CMOS battery from your motherboad and wait a minute, sometimes there will also be a jumper you can switch the says "CLR CMOS" or something similar. This will set all your BIOS settings back to default.

EDIT: Just noticed you said you rest the CMOS. Sorry. Sometimes it takes a bit longer for some boards to clear out, so you may want top try again and wait longer before putting the battery back in, and be sure to have the machine unplugged at the time too.

Some mobo's reset if you hold down the insert key while powering on.

Hi, "Thanks Again" the hold power button & reset button on the mobo worked for now, but when i restarted the comp, it happend again, maybe i have to re update the bios to keep it stable? Note: the mobo has post lights CPU-DRAM-VGA.ext & it's getting stuck on the DRAM light & the graphics card will not
power up.

I agree "if its not broken dont fix it"
But i have a mobo that is designed for overclocking,
Question is will overclocking 24/7 shorten the lifespan of your hardware?

I'll post back once more when its 100% stable.

You have to understand that there is no guarantee that ANY overclocking can ever be done on any component, and even when overclocking is possible, there is no certainty of the degree which your particular component, batch, or combination of components can be pushed.

And to the question of overclocking shortening the lifespan of your components, there is always a chance that pushing hardware past factory specs can cause hardware failure. I myself have been overclocking for a few years now as far as I can remember, I have only burned out one motherboard, and that was a board I abused the hell out of, both by overclocking and moving it case to case, adding and changing components every other day, etc.

My only personal experience with long-term overclocking is my daughter's rig (you can see it in my sig). I built that machine, set the CPU from 2.66GHz to 3.2GHz, and she has been running it like that practically 24/7 for almost 3 years. that is with a stock cooler and stock voltages.

And the way I think of it, so what if you are taking a CPU or graphics card and reducing it's life from 7 years to 5? Most of us here (at least it seems to me) perform major upgrades to our CPU's or whole platforms about every two years, and upgrades to our GPUs every 12-18 months.

Hey, good luck with it. If you need more info on your particular setup, there is probably an official thread or club around for each of your components where you can get more info than you can absorb.

EDIT: I went and found the info thread for your motherboard and the overclockers club and database for your CPU. Both of those threads should give you an idea of what kind of overclock you can get with your combo. You can go on there and see just how much of a difference there is between batches, motherboards, cooling methods, voltages, etc.

Thanks Heaps for that & i will look at those links, & thanks also for the info on the overclocking & components, it sounds like common sence, + im well overdue for a GPU upgrade, i just replaced my older PC/ASUS Crosshair Formula II with AMD Phenom 9850 Black Edition Quad @ 2.5GHz & 8GB Kinston HyperX DDR2 @1066MHz which my son is using now, i liked the speed of his older Intel Core 2 Duo, so i got on the intel nipple.lol
Note: i might have fixed my problem now? but i'll need to restart to make sure,
this time i pushed the power button on both the mobo & case, when i was pushing the reset & power i still had issues (fan speed warning) because im using liquid so i disabled that in bios but then it would not boot again.

P.S. Thats a nice Setup you have done for your daughter & i have one of those clear case's that i might put to use one day, as i have 3 sons & 1 daughter.

Hi, The PC is running OK now & back at defult settings, Thanks for the help.

Note: the 9800GX2 has been buggy at times due to the heat it puts out,
& i even had to bake one side of it, due to it failing
i never used Rivertuner for it before, but since i have & use 100% fan speed, the temps stay down
& not i'm really interested in liquid cooling it,
as i need a mager upgrade very soon.
ASUS 9800GX2 1GB = SLI
Leadtek 8800 GT 500MB = PhysX
