1st overclock gone bad...HELP!

[Mabica]

hi

today i tried to overclock my i5 650 processor on my dh55hc bord and all went wrong.
im not sure what i did wrong but as i finished changing some settings and restarted the PC, the display stayed black, although the fans where all functioning. and it didn't sound any error beep. i tried removing my graphic card and use the on onboard one but the problem persists (i thought it was only a display issue). i dont think the problem is that big but obviously i cant solve it so please I NEED HELP!



my system:

intel core i5 650 on DH55HC MB

8 GB DDR3 memory

GTX259 graphic card
intel X-25M 80GB SSD + other 2 1TB drives
Cooler Master ucp 900w

Plus can anyone guide me to obtain a stable 4.0GHz on my system...

Going straight to 4.0 is not for n00bs. What's your cooling? Did you change the CPU voltage? Did you adjust the memory multiplier? There's a lot of things that if you didn't do them the OC would totally fail and you would get a black screen.

Obviously you are new at this : think about your train of thought after you set the overclock. RIGHT BEFORE you overclocked your cpu, you system was booting fine and the video worked. Right after, black screen. Just maybe this was due to something related to the CPU and NOT the video card.

For example, if you didn't increase the voltage, the CPU will totally fail when you try to overclock and the video card will display nothing (black screen)

If you didn't adjust the memory multiplier, and you were trying to run you RAM way out of spec, then the same problem : CPU would be unable to access it's RAM and black screen.

And several other possibilities.

If you can't get to the BIOS, check your motherboard manual. There's a way to reset the BIOS that will clear that faulty overclock setting and let you get to the BIOS.

Many motherboards just have a CMOS reset button on the board instead of a jumper. Try that and see if it fixes your issue. If not consult your manual on where your reset jumper is located. A few motherboards I have used even have a CMOS reset on the I/O plate also.


Pretty sure a reset will get you back to operational.

Just reset your cmos jumper, getting a black screen is part of finding your max overclock at times.

You should copy someone else on settings if you're new to overclocking, that will at least give you a feel for how much voltage you need and like Habeed suggested, inform you of what other settings that might need change.

thanks guys, but i cant even reset the bios. the manual refers to recovering from a faulty upgrade, not reseting it. although i tried (as said on the manual) to save a .bio update file on a usb drive and restarted the pc without the jumper and still nothing...

heres the cmos jumper instruction:
1-2 - normal (default)
2-3 - Configure (after POST runs, the BIOS displays the maintenance menu. use this menu to clear passwords)
(none) - BIOS recovers data in the event of a failed update

i tried all combinations and nothing...

From Intels website for issues related to your motherboard:

http://www.intel.com/support/motherboards/desktop/sb/cs-010254.htm

Certain changes in BIOS settings (such as chipset timing or latency, memory timing or latency, processor clock frequency, etc.) can cause a system to no longer boot.

If you are able to enter the BIOS Setup by pressing F2, reset the BIOS to factory defaults by pressing F9. Save and exit the BIOS Setup.

If you cannot enter the BIOS Setup, clear the CMOS:

1. Turn off all peripheral devices connected to the computer.
2. Disconnect the computer’s power cord from the AC power source (wall outlet or power adapter).
3. Remove the computer cover.
4. Locate the battery on the board (see figure below).
5. With a medium flat-bladed screwdriver, gently pry the battery free from its connector. Note the orientation of the “+” and “-” on the battery.
6. Wait one hour then replace the battery.
7. Replace the computer cover.
8. Plug the computer and all devices back in.

You may also need to perform a BIOS Recovery after clearing the CMOS.

The idea is to move the jumper to the 2-3 position, then move it right back to the 1-2 position before starting up the computer.

Nice help/posts, great forums! Why I love coming here.

 

[Mabica]

nothing does seem to work. i even removed the batery for hours (with all cables unplugged) and nothing...

 

[Mabica]

any other ideas?

 

[bryanW1995]

make sure you reconnected all your cables correctly. One time I was oc'ing and forgot to plug the 6 pin pci-e connector back into the video card. ah, the memories...

 

[EliteRetard]

any other ideas?

Kick it across the room and back, it worked for me. I also smashed up a video card and threw that in the case. Show it whos boss.

hehehe. i'll try that at some point...

i though of that also. i unplugged all and plugged all back carefully...and no POST!

try the cpu in a different mobo, or get another cpu and put it in your mobo. you may have fried something in there. high unlikely its the CPU, but you need to rule out the possibilities.

 

[Phunk0ne]

unplug all cable, inlcuding any USB cables if attached, take out the little battery (round button battery).
leave it like that for another 3 minutes. Hoop up minimal of hardware to get started
i.e. HD, keyboard, mouse, graphics.

 

[Ruger22C]

Did you leave the CMOS jumper in position 2-3 while trying to start the PC?
That can cause damage.


You also didn't tell us if you changed the voltage.

That can kill a CPU.

 

[BD231]

If funk ones info fails you your motherboard has an issue defaulting bios settings when you clear your cmos, I've seen it before on flaky motherboards. Some boards come back to work fine after a million and a half attempts to clear the cmos, some don't come back at all.

If I were in your position I'd fiddle as much as possible, if I didn't get it to start I'd RMA the motherboard. You don't want to keep a board with odd cmos issues, in my expeirence that's a ticking time bomb.

 

[Phunk0ne]

During my OC sessions with my trusty GA-P35-DS3R, I ran into similar problems.
even though I tries to clear the CMOS using jumpers, nothing happened.

So I unplugged everything, all cables except for the power connect to the motherboard, left that on, i did unplug the PSU from the wall.

with everything unplugged, I pushed the power on button on my pc, making sure it would discharge everything from the PSU, waited 30 minutes (good time to sit back and have a coffee )

After that, I reconnected only the necesarry hardware, HD with windows installed onto, graphix, keyboard and mouse. . . "et voila" . . . worked for me and I could continue overclocking....

Needless to say, this almost became a daily routine during my overclock sessions when I tried to reach 4GHz with my E6750... ended up @ 3.9GHz @ 1.525V in bios

 

[Soccerman06]

My first guess would be you fried the CPU from not turning off autovolt.

Does nothing turn on when you press the power button or does the psu/hdd/fans power up.

After many different possible solutions tried, the prob was solved. i had to remove the mobo from the case, install a different cpu. then it was all (my old i5) back into the case (i had to remake all cabling ) and PROBLEM SOLVED! not sure what was the problem though...

anyway thanks a lot to all yall

 

[Mabica]

Since my first (bad) experience is over, I'm into overclocking again!

can anyone guide me this time? my goal is to achieve a stable 4.0GHz, with minimal possible voltage modifications.

My system:
MOBO: Intel DH55HC
CPU: Intel Core i5 (@ stock speeds)
CPU Cooler: Cooler Master V8
RAM: 8 GB DDR3 1333
GPU: nVidia GTX295
HD: Intel X-25 G2 80GB SDD
PSU: Cooler Master UCP 900W

Not sure if you can do it with that motherboard.
