Failed overclocks worrying me

post #1 of 26
Thread Starter 
Ive been wanting to get my rig running on a stable overclock for a long while now, but i always get a BSOD or something and then wuss out back to stock settings.
I took bits from several 1055t OC guides and came up with the following settings:

300 FSB
12x ratio for 3.6GHz
1.42 Vcore with LLC high
1200MHz RAM @ 1.55V with 9-9-9-24
2700 CPU/NB @1.3V with LLC regular
2100 HT link

But when i saved the changes and restarted, during the the post it played me a lovely warning siren and had a red LED next to my RAM.
So again, im back at stock.
What am i doing wrong?
I just cant seem to ever get it right.

To get your Ram from 1600 default to 2400MHz, you'll need a lot more than just 1.55v (& much looser timings).
Try reducing your ram speed to deafult and once your CPU oc is stable, start oc'ing the memory thumb.gif

Erm, im running it at 1200MHz... 400MHz below its default speed.
And 9-9-9-24 are the recommended timings for Corsair vengeance.

You mean you're running it at DDR1200 , which is 600 mhz , instead of DDR1600 which would be 800 mhz and actually 200 lower than it's default value wink.gif

Just leave your Ram at stock and get your CPU stable first. Also keep in mind that some chips don't OC as well as others of the same batch. Know how is half of it but it's also luck whether you get a chip that Oc's well or not.

I just cant seem to ever get it right.

When MemOK (red light) activates on boot,it usually means RAM timings are off. If I remember correctly, you have to wait until it restarts by itself,as it will test and adjust the RAM timings. It may take several boots for the whole process to finalize. The thing is,if you don't let it go through the whole procedure and go into bios and change settings again,it will confuse it.
The other option is to do it manually, inputing all RAM timings,no auto.

Have you tried turning LLC down on CPU? High LLC can often lead a wide variance in CPU voltage.


And lastly what are your temps? You just may need more voltage.

Ahh, thats the one tongue.gif
Sorry for the confusion!
Its just my BIOS refers to it as the current memory frequency with it at 1200

Do you already know if your Motherboard is happy with a 300 FSB? Maybe run it a bit lower (275) with a higher NB Multi.
If it POSTs fine then you know where to start at least.
Everything else looks ok, loose Ram, Medium CPU OC.

If i leave the RAM at stock, when i bump up the FSB to 300, the RAM goes from 1333 to nearly 2000, so i put it back as close to stock as i could.

Oh... So i shouldnt have shut it down and restarted?
Ive just looked up the POST noises and none of them seem to fit...

One short beep:
VGA detected
Quick boot set to disabled
No keyboard detected

One continuous beep followed by two short beeps then a pause (repeated):
No memory detected

One continuous beep followed by three short beeps:
No VGA detected

One continuous beep followed by four short beeps:
Hardware component failure
It normally does the short beep on startup, which is fine. But this one seemed to be a continuous set of short beeps, and there were more than 4.

The LLC works on stock CPU settings, so it isnt that causing it i wouldnt say.
And my idle temps are 25c Vcore, so about 35c in reality.

At 1200mhz you should use tighter timings. My ram is rated at 1333mhz at 9-9-9-24 but when i run it at less than 1333mhz i get ram related bsod's. Using tighter timings actually helped. Can you upload a cpu z screenshot showing the SPD tab.
