I foolishly tried to overclock my RAM to 1866 mhz without getting into xmp or messing with voltage (was at 1.5v i believe), no my system will turn on all fans are spinning but i get no video signal, nor any error beeps, nor error codes in the LED dr. debug thing.

I've tried clearing CMOS thrice, in a different way every time so now i really think i fried something.
My components are: AsRock pro 67 SE
i3 2120
2X4GB Corsair Vengeance (only rated for 1600mhz)
EVGA GTX 550 ti

Any one got any ideas. I'm thinking i fried my cpu's memory controller, but no way to be sure for me, i dont have a spare processor to try.
Any info would be greatly appreciated

Not sure how this thread was resurrected, but it is being cast back down into the pits of Tartarus.

Nope tried that, no difference there. I even tried without any memory sticks, just to see whether it would throw me an error code, which it would in that case right? But i got no error code whatsoever with no sticks in.

Try unplugging power supply, hold power button for a minute to discharge capacitors, clear cmos, remove battery also if easy to get to. Sometimes its what's needed to get back up and running.

YUP, go full procedure.

It's almost impossible that you fried something. ;)

Can you link your exact memory kit specs?

i've tried removing battery before, tried the clear cmos button, and tried the doing it with the jumper. But i'm doing it again since i hadnt pressed the power button before. It's good enough to unplug the power chord right or do i also want to disconnect the powersupply from the motherboard??

What motherboard do you have? I know the gigabyte z68 boards are picky with that ram <3.

Edit:, NVM original post has specs.

Did you increase the voltage to the ram during overclocking, or to the board? If you cant get it to post at all, even with different ram, it's possible the bios is corrupt / the board is dead.

Personally what I do in these situations is pull out the cmos battery, take a shower *aka wait 30mins*, come back and plug it back in and she works fine.

Generally the cmos battery needs to be out for at least 10 mins to get a good solid clear.

I hadn't increased any voltages whatsoever. The first time i took the cmos battery out i left it out for 2 hours but i hadnt pressed the power button to discharge the capacitors so...

Something interesting happened after i reseated the CPU, i got an error code: error code 30 which according to my manual means "System is waking up from the S3 sleep state"
Then when i try to press the reset button thats located directly on my motherboard, it gives me a code 19 for only a milisecond and goes back to 30. Code 19 means "Pre-memory South Bridge initialization is started"

alright after once again taking the cmos battery out for several hours i was able to boot with one stick in the last slot into bios, there i changed my ssd setting to achi so i could get into my OS'.

I have to admit I've fried a good amount of components and every time i just make an educated guess, replace it, and lucky me that was it, but is there a better way of doing this, say a voltage checker of some kind to be able to exactly pinpoint your dead part??

I still don't think you actually broke anything.

The problem with modern motherboards is, there are so many settings available, that a few of them will get STUCK, even upon a CMOS reset.

This is likely what is happening to your board.

As of now, simply get all your bios settings back to stock.

Input your memory timings and all voltages (cpu, ram, vccio, pll) manually

ASrock motherboards like to corrupt the bios if you set unstable bios settings(or atleast permanently brick the system).
I've seen over half a dozen reports of this in the last few months.
An asrock motherboard I purchased a few months ago did this.
After reading the newegg reviews several others had the same issue, I had to flash the bios with an external programmer to make the system post again.
This is what it sounds like to me.

Oh, hmm... I didn't know this was a common issue. do you mean corrupt the BIOS, or corrupt the BIOS settings. :|

I've heard about this. The BIOS is there, but it's no good. It either gives settings that don't work, or just never gets to POST.

One of the reasons ASUS' USB Bios Flashback is the greatest feature. BIOS corrupt? as long as you have power to the motherboard (don't even need memory or a CPU installed) you can flash the BIOS via a USB flash drive with a single button.

This. I had to do this when OC-ing my memory from 1600 to 1866 while playing with latencies. I had the black screen and no bios boot several times before finding the limits at my particular voltage (1.6). Your processor is likely (99.999999%) fine

good news; your system is most likely fine; bad news; you've most likely borked your bios......

Not is all lost; we have a thing called ebay - wonderful place to do a search for latest bios chips for your mb...*last time I borked my bios chip; had to get a replacement for 10 quid* Will most likely cost about 12 dollars....make sure you get one with a bios chip puller...

They are super easy to replace....comes with the latest bios and should get you back up and running in a couple days.......for that I don't fear borking bios chips anymore :)
