Having trouble OCing

I've got the CPU running at 266X10 with a 3.00 multiplier. I can run 3DMark06 and HL2 demo, so this seems rock solid.

Now, I keep hearing that 3 GHz or 3.2 is a piece of cake, no problem, etc. But I can't do it. Since 2.50 is the next multiplier below 3.00, I've tried 320X10 with a variety of VCOREs and other voltages. No joy. The board usually resets to 200X10 A couple of times, I got it to POST at 3.2 GHz, but it can't do anything... can't boot Windows, can't even get into the BIOS.

What's the secret? I could really use some baseline values. I'm just wildly guessing. I was trying to slowly up the VCORE, but people say "More VCORE!" How much more, I ask, and I never get a response. I hear talk about changing memory voltage, but do not see any such option in the BIOS.
 
I'm a little confused.
In "266 x 10", 266 is the FSB and 10 in the multiplier, as in 266 x 10 = 2.66Ghz
What is the 3 that you are calling a multiplier?

Click to expand...

Must be the FSB😀RAM divider.. 3.0 meaning 2:3/1:1.5, 2.5 meaning 4:5/1:1.25

I'd say it's never a piece of cake to OC to the numbers other have got. If upping voltages won't get you to 3Ghz and there's no problem with your memory sticks and your cooling is working properly, I'd say you've just got bad luck and your chip is just hitting the wall earlier than some others. I'm not an expert with OC troubleshooting so I can't give more specific advice as what could be the problem.
 
Tried putting your RAM on a 2x multiplier and loosening the RAM timings, make sure your RAM isn't the fault?

Another thing you could try is put everything on STOCK voltage, or auto voltage, whatever....put your FSB to 334MHz, and your CPU multiplier at 9 instead of 10. Your RAM will run at 667MHz not 800MHz, but hey. That should work. RAM at a good speed and your CPU will be 3.06GHz.
 
the problem probably isn't with your chip, it's the ram...set your divider to 1:1 at first so you know ram isn't the problem...set FSB to 300 with a 10 multi = 3ghz. start with voltage of 1.375 and keep upping (1.385, 1.395, ect.) until you can boot into windows. I'm using the same chip (2180 @ 1.465v) and i'm not having any problems. do that and you'll be all set. just keep the ram timing to 1:1 until you're stable at 3ghz, then start playing with the ram timings.
 
yeah, the advantage of running (for example) 800 mhz ram versus 667mhz ram is nonexistant for real world stuff. Maybe for bandwidth benchmarks but seriously...

Set your RAM to 1:1, and match the SPD's timing specs (manually). This is probably 5-5-5-15.

If you're running @ 667 mhz on 800 mhz modules, you can usually get away with 4-4-4-12. I certainly can.
