Thanks...I think all that's left now is getting my temps down, not sure if I can really do too many other tweaks. I was able to grab this over my old overclock by dropping a few degrees...
Time will tell. ;)

With this MB i have a very big problems with MSI 790FX-GD70 I expect 4,2Ghz full stable. ;)
Hello!
I have something here.

feniksgod: very nice stable clock 3.95MHz! Whau.
Sorry to say but i see you already stopped Prime and the CPU cores are still 56ºC, i think you reached the limit with 1.55VQuote:

4GHz Prime stable is already a nice achievement. :up:
AM2+ socket required more voltage than AM3 to stable a frequency.Quote:

My CPU seriously seems to suck on the CPU department :P I can reach max stable at 1.5v 3700mhz , decrease the voltage below the magic 1.5v mark and it's unstability when I stress it, same goes for upping the MHz by one node (HT ref.)
But my NB has no issues running 2800mhz @ 1.4375v and has passed stability testings so perhaps I have a good IMC :rofl: Should I try pushing my RAM abovee 1333mhz 6-6-6-18-24-1T?
Have seen a few guys reaching higher clocks @ lower voltage HT ref. clocking instead of multi clocking so will try that approach after work
Well 3.7Ghz seems to be a stable and achievable OC for most 720be owners on air. So dont worry about that. Have you managed to unlock the cores yet. I am at 3.5Ghz on the 720BE with 4th core and around 3.7 with the core locked. My only issue is I am unable to get the CPU NB to run at anything higher than 2.4 as the multi is playing up.
By browsing the results in this thread it becomes obvious the 720's do not oc as well as the 955's for example.
For some strange reason some of the dual core phenoms do better than the tripple cores, even with 4 cores enabled.
Getting 2.8GHz out of the NB is nice but 1.43V is quite a lot to achieve that, don't forget you are adding a lot of heat to the cou temp by raising Vnb.
Mine runs 2.8GHz with 1.32V fully stable and is able to do Spi1M at 3050MHz with 1.38V, adding more volts didn't do much really.
Looks like it's safe to say the 955BE overclocks better than the 720BE in both cpu and NB and better than the 940BE.
I can't wait to see what the 965BE will do.
Make shure you are using 1.2 - 1.3v for the NBvid or NBvolts on CPU.Quote:

Thanks, but issue is with the current bios that I am using(in my sig). So I turn it to FSB 250, multi on cpu to 14, now the NB will clock to 2500. But if i up it with the multi, it wont boot.
Thanks to my new Koolance WC setup, I have been able to get better results. Not stable, will tweak some more this weekend.

Looks like a nice cpu.:up: I have a suckage 940 that does 3,8ghz stable on water and 3,6ghz on air with MA790GP-DS4H. Next week getting an Asus M4N82 Deluxe, will see how good that 8-phase vrm is.:) Btw, who´s that on your wallpaper?:DQuote:

Just a small question..Quote:

So far I can reach 3434Mhz @1.475v prime blend 8hs, linkpack 10 rounds stable. My NB stays at 2020Mhz @ +0.25v in CPU-NB.
In order to raise NB freq, should I raise CPU-NB -AND- NB voltage in bios or only CPU-NB?
Look to increase cpu nb...
Not 100% sure - I have to test a bit more - but nothing seems to happen raising NB multi and adding CPU-NB +0.1/+0,2v. Is not my prime priority to OC the NB, I´m only seeking to gain CPU stability at 3.5Ghz. I wonder if there are many people at 3.5 / 3.6 Ghz with NB at stock speeds... or is absolutely necesary to OC the NB to arrive to that level
No, you can oc the cores regardless of what speed you run the NB at. Ocing the NB gives a nice boost though.
check out the core vs nb vs ramQuote:

Hyper transport can stay the same.
Many people are saying the same. But if I up the NB speed to 2200 or 2400, even adding voltage to CPU-NB +0.075, 0,1 or even 0,225v , my system fails blend @3.5 ghz in a minute or less...weird thing. It seems it likes default 2000MhzQuote:

Nice but waiting on the 4 ghz mark on that chip
Its next to impossible in the crap Hao7 from Jetway :@ Maybe I can save a bit and get UD5P:)
getting a feel for this 955,on chilled water.
