955 BE overclock hitting wall

i have a 955BE with GIGABYTE GA-MA790GPT-UD3H , gSkill 1600 ram, a 750 watt bfg PSU and a Thermaltake CL-P0464 DuOrb 80mm CPU Cooler. i just cant get a stable overclock over 3.8ghz. why is that. i have the vcore at 1.45. i have moved it as high as i want, but anything higher than 3.8 and it will boot but not load my linux. it will show errors and freeze up. i have tried increasing the FSB and the Vcore. how are people getting these high overclocks. im not getting hotter than 45degress idle and 52 with load. so i need it cooler to run higher?

You should be very happy with that OC. My 955 hit a wall at 3.6. Some chips do not clock as high as others, but you could try upping your NB/HT and your NBVID by +0.1.
Yeah, that seems to be the limit for Phenom II's. Nice OC.
For that exact reason, I sold my AMD 940BE and bought a i7-920 D0 and it has been worth every cent! 4.4ghz on air (lapped TRUE with ultra kaze 38mm fan) prime stable with only 1.4v! my 940 struggled to get stable at 3.8 with 1.57v (and wasn't really even stable) with the same fan and heatsink... I am not bashing AMD by any means seeing as I have been an AMD fan for a very long time, actually, that is all I have EVER owned until now, and unless they start really making some changes I won't be back.

I went from a stable 24/7 clock of 3.7ghz at 1.52v on my AMD to...

My current i7-920 that is 24/7 prime stable at 4.0ghz with only 1.29v, and 4.4ghz 24/7 stable at only 1.4v with temps that never even reach to 70*C! I can't wait to see what it will do on water!!!! I would never even think about this kind of clocks with my AMD 940, hell, I even tried extreme cold once when it was -18* ambient and i put my computer outside to see what it would do and i was chip limited to 3.9ghz, and that was with 1.6v!!! If i put my i7 outside with the same temps, there is no idea what this thing would do.

Also, my AMD's best 3dmark06 score was 21,XXX (out in the cold), i just nailed 28404 with my i7 system at 4.4ghz tonight with the same 4870x2 i was using with my AMD, and was doing this with an ambient temp of 24*C, and both systems were with only 4gb of ram (yes, i know the i7 is triple channel, but still...)... If you really want to have something to play with overclocking, I highly recommend selling yours and buying an i7 system... I use to hate people telling me that when i was wanting more out of my AMD but now that i have experienced it first hand, I can't believe I waited this long to make the move to i7!

Best of luck buddy.

Just wondering what you use your PC for at 4.4ghz or 4ghz that it chouldnt do at 3.7ghz on your AMD beside higher benchmarks? To the OP as stated by others some OC better then others so you might be at the limit, as for the temp at load I think its fine my will hit 53c while running prime for a bit. If you look at 9*5 sticky you will see that some people need lots of volts to break 3.8ghz

Encode high def video in about or less than half the time it took my amd (I make a ton of youtube videos, and general family videos), its a ton faster at anything i do when producing music (i am a amature writer/music producer), benchmarking is 6000+ points better even with the same video card i was using on the AMD, there is tons of overclocking headroom which makes it a hell of a lot more fun to overclock... Hell, what isn't better other than the price point which goes to AMD, and honestly AMD isn't cheap enough to really make that much of a difference now, especially when taking into consideration the huge performance hike you get with an i7 system over AMD.

And again I would like to point out that I AM a huge AMD fan, but they honestly just don't have anything to offer me right now that meets or exceeds my needs.

i dont do any of that stuff at all. i watch hi def videos and at 3.8ghz, i never go over 10% of usage. and i only use one core when i watch hi def. the cpu tears apart anything i throw at it and it was much cheaper then the comperable i7 system that i thought of building. i just wanted to know what u do when u hit a wall at overclocking? do u get a new cooler, switch to water. if i ciouldnt get it at 30 degress would it clock higher?
if all you are doing is watching HD movies, you don't even need to overclock for that, you could do that at stock, and even with a lesser cpu than what you have now! Seriously, if that is all you are doing with it, put it back to stock settings or even under clock it a little and save yourself some electricity!

Also, water cooling helps a little, but if you have reached the ceiling of your chips clockability, not much less than extreme cold like L2N, Dry Ice, or Phase is going to help you much in overclocking.

Try putting it in a your fridge LMAO J/K

3.8Ghz is a high overclock for a 955BE, 600mhz increase, you should be happy man.
