I have a GD70 and anytime I try to OC the FSB my PC will go into a reset loop. If I try to change my FSB from 200 to something higher in the BIOS it will either become very unstable or fall into a loop where it will constantly reset itself until it comes back on its own and tell you that your prior OC has failed. Those familiar with this board also know that it has a "Max FSB" function in the BIOS that will find a max FSB in about 10 -15 seconds after a reboot. When I try letting it find its own max it will simply fall into a reset cycle and will only recover if I clear the CMOS.
I'm able to change the FSB in windows but only by using the OC dial thats built into the board. If I try to change it in AOD nothing happens. My PC starts to think and apply other settings I use in AOD but my clock speed won't change and my NB speeds won't change. I can change any other setting in AOD with no problems.
Using the dial I moved the FSB little by little running a Custom Prime run (512K min, 1024K max) at each setting for about an hour testing for stability. Once I hit 210 Prime will start to fail at 640K - 512K and sometimes my PC will BSOD and reboot.
Leaving the FSB at 200 I started doing Prime custom runs (512Kmin 640Kmax) with just a multi OC of 3.6(200x18) with CPU volts at stock and NB volts at 1.2 and again my PC will BSOD after about 10mins and restart. I've also tried lowering the NB multiplier and increasing the FSB in the BIOS to try and even out to around 2000 but it will just fall into a reset loop when the FSB is over 205.
I don't think temps are a problem with my Sig cooling. I idle around 28 -30c and under 100% load it never gets over 42c.
All this troubleshooting as pointed me at either a bad NB on the motherboard or a bad IMC on the chip and I'm really hoping its just the motherboard. Any ideas or suggestions?
Here's something I posted in the 955 OC thread and figured I'd give it a try here and see if anyone can think of anything. Also, I've tried every BIOS from 1.1 - 1.3 with the same results. I'm leaning towards a bad MB and hoping that if I RMA it I won't have the same type of luck. I really like the layout of this board and it has the highest memory OC standard for any AM3 out there...
Plus I really like this club
