I tried overclocking by using the turbo but it didn't work at all. Just stuck at 3.4GHz on all cores with IBT :confused:

I resorted back to my multiplier+C2 but it would only initially go to 4.6GHz, a few days later it let me go back to 4.7GHz...haha so I think i'll stick with this way for a while before I attempt to try turbo overclocking again.
 
Will these settings apply to the MSI Big bang Marshall?
Just had mine delivered along with a 2600k and will be having a mess about with it tonight.

That's strange, did you increase the long/short duration power limits? either way gets the same result though ;)

That board looks awesome, let us know how you get on.
 
Just messing now, although need to find some nuts for the cooler so using the intel POS!

Anyway 4 GHZ on stock everything and BF3 hits 70c, idle is 30 -34. Cant wait to stick a H80 on it though.
 
I'm surprised the stock HS does that well :D I have a custom loop with just a 120 rad and push pull fans, @4.5 the temps max out about 55 when gaming, intel burn test will push low/mid 70s. I guess a H80 will be similar.
 
Right, finally got cooler installed. Fired up at mp x40 and running prime

How are we looking so far? Everything other than the mp is stock.
 
To boot at 4.5ghz i have this, everything look ok or am i doing something wrong?

CPU-z more accurate for v core than bios?

Hi, sorry for the stupid questions as I don't know a huge amount about overclocking and would like to just get my chip to a half decent overclock then leave it there and not worry about it any more.

I followed this guide (I have the GD55) which was great and have managed to get to 4.5 which I am happy with and seems to be stable.

Could someone just check the above settings/temps which were taken whilst running prime and let me know if it all looks ok to go with this 24/7 on my PC.

Temps are around the mid 20's in windows idle, although for some reason seem to be higher in bios (high 30's)

I seem to have it working as described in the guide where CPU drops low when not under load.

Also is running it as above going to shorten the life of the CPU in any way?

Thanks
 
It looks good, the voltage seems to be about average for 4.5 with auto voltage. The temps seem pretty good too.
The temperature in BIOS is about 10 higher for me as well, I think it's common on these boards, don't know why.

I'm not sure about shortening the lifespan as there could be a risk with any overclocking.
Having said that, you do have good temperatures well under the max,
and your voltage is within Intel specifications, so chances are you will be fine ;)

I've tried pretty much the same settings except set the CPU PLL to Auto because I noticed yours is an i7 and I am not sure if 1.8v is too high for i5 2500k.

Anyway, my clocks don't go above 3.4Ghz :/ any ideas?

Cheers
 
That's a strange one, I had a problem of down clocking due to a bios bug, but not overclocking at all is a new one.

Just confirm; Under the "Overclock Settings" tab, EIST and Intel Turbo Boost are both enabled. Then check the "Core Ratio Limit" values under "CPU Features" this is what sets the overclock.
