I have never been able to get Orthos or Prime stable at anything over 3.21 ghz, and that requires 1.45 volts to be stable in an Orthos test overnight. Any less voltage and I get a rounding errors within an hour or two. I have managed to boot up to 3.3 at anywhere from 1.475 to 1.55 and can run Super Pi up to the 1M digit calculation with no problems, but Orthos fails due to a rounding error immediately below 1.5 volts, and generally fails within 2 minutes from 1.5 to...
Hello all. I've been reading this thread for some time now and it's been very informative. I have been running one 4830 since the middle of January, and just today received my second and set up Crossfire. Here is my validation. http://www.techpowerup.com/gpuz/b4zsw/

I've boosted Vcore and NB voltage to 1.5v. I've clocked everything down and tried getting over 3.3 with low multis and high FSB. I've clocked the RAM and HTT down too. No...
I am trying to determine why my processor seems to be a bit more volt hungry than most. I have fully stable 3.2. Orthos verified for 12 hours with no errors, but it takes me 1.45 volts to get there. 3.2 will run down to 1.36 volts, but it will generate rounding errors in Orthos and crash on occasion. At 1.45 it is rock solid, not a single crash or Orthos error. I can run 3.3 at 1.47 but get a rounding error within a few minutes. I have added voltage up to 1.52 but...
I was in a similar boat. I could not get over 3.0. 3.1 would bsod in prime fairly quickly but 3.0 was stable. Then I started tweaking the CPU-NB voltage and things got better quickly.
Ah yes, now we are getting somewhere. I have not tested stability on this yet, but progress is being made. 1.47 volts http://valid.canardpc.com/show_oc.php?id=504614
The Biostar TForce TA790GX can be had for under $100 and is fairly close to the price of the Gigabyte you mentioned. The best part is that this board is getting some very good overclocks out of both the 7750 and the 940 Phenom II. http://www.newegg.com/Product/Produc...82E16813138128 http://www.motherboardpro.com/BIOSTA...il-p-1259.html
Your best source for overclocking this cpu is going to be found here: http://www.overclock.net/amd-cpus/45...0-oc-club.html With that said, posting your system specs into your profile so that we can see them is going to be a great deal of help for anyone trying to assist you with your issues.
Well I have made a bit more progress with this chip. It seems that the key with this motherboard is a setting labeled CPU-NB voltage, which apparently needs to be the same as the CPU voltage. Before I was leaving this to auto, or to 1.325, which seemed to be the default voltage, and I couldn't even boot the system at 3.2 ghz. 3.1 would run a couple of hours at best. Now that I am setting this the same as the CPU voltage I had no problems running 3.1 for a few hours...
He is not the only one having issues. I cannot run 3.0 stable at stock voltage by just changing the multiplier. For stability at 3.0 I have to run 1.35 volts, and I am still unable to clock any higher with stability. I am beginning to wonder if there were a bad batch of processors that went out or something.
