E6300 overclock woes

My E6300 came in today, and I finally slapped it into my Gigabyte DS3.

I was very impressed, as I got past 400 FSB, and it kept going. Then it hit a wall at 425. I managed 428/429, but now I can't go back. It's really iffy.

I'm not sure if it's my Mushkin 6400 5-5-5-12 RAM, but seeing that most people managed to get past 3 GHz with 5300 RAM, I have no idea what's wrong.

Any ideas? I'm sure the heat is fine right now as the temps are below 60c, and the voltages are sufficient. I've got my RAM running at 1:1, and unfortunately, the board won't let me downclock the RAM to give it a bit more headroom.

I've manually set the ram to 5-5-5-12, and for some reason, CPUz reads it as 3-5-5-15.

Basically, it still post if I take the OC too far, but the board sets the overclock enabling feature to disabled, thus, rendering the board back at stock speeds.

Right now, my FSB is at 425, but seeing some people get 450+ is really disappointing me. I was hoping to at least hit 3 GHz, or pass it a little.

Any ideas?

 

well it might be becuase of the different ram. or its the board for disabling oc features. it could also be that processor chips are guarenteed to give you the stock speed; anything over that is luck. some people just got a bad processor.

everyone i have seen barley got up to 3ghz on it.

 

No more ideas?

 

nah sorry, wish i had more ideas. it seems as if it was the ram giving it a problem since it is cas 5 as it is plus i dont know nothin about that ram company.

 

Well, I have burned it in for a while, and it's pretty stable at 425 FSB.

The problem is, that sometimes, when I restart, the OC settings reset themselves, and they won't overclock as high anymore, unless I fidget around with the settings a lot.

Worst yet, now I'm stuck at 420 FSB. It's like going backwards! I'm guessing this is a BIOS issue.

Any ideas why? Should I relax my memory timings further, and hope that gives me some more headroom?

 

Tried updating your BIOS?
That may give you the option of changing the RAM speed?

 

Yep. Unless something is newer than F4c, I'm out of ideas.

The problem is that it just restarts, and resets the BIOS. Well, not really. The settings remain, but the CPU Host Clock Control automatically switches itself from Enabled to Disabled.

I can't even get 400 FSB anymore. It's so random. One moment I can get 429, now I can't get 400.

 

OK.

I've figured out that I can overclock to 425FSB, but only when I have NO USB devices attached.

Is this some sort of BIOS error!?
