Maximus II Formula - OC Issues

post #1 of 5
Thread Starter 
Hello, I have a Maximus II Formula which I would like to use a my computer's motherboard. My P5E still runs, but the top PCI-E 16x is stuck in 8x and a copper trace on the back has peeled off. While it still seems stable, I rather use the MIIF due to this issues.

With the MIIF I am having problem achieving the same 3.6GHz clock with my Q6600. I've been able to successfully boot at 3.2GHz and it appears stable. However, I can only successfully boot the computer if I set 3.2 and then bump up to 3.6GHz. If I restart or the computer crashes, I need to load to defaults in order to POST.

When I am able to boot into Windows at 3.6, LinX always crashes ~5 seconds in and I get the 124 BSOD.

I've increased vCore and FSB Termination Voltage, but neither seemed to make a difference. My current MIIF settings are below. Note the the voltages being used on the MIIF are approximations since I don't recall the exact decimal values and should be the same as the ones used on the P5E.

Try those 400MHz FSB settings with 6x CPU multiplier and test it in P95 Large FFT for couple of hours (6x 400 = 2.4GHz) ..

Also set STRAP to AUTO and RAM manually @ 800MHz..

You don't need more than 1.30V for North Bridge @ 400MHz FSB as MFII has P45 chipset not X48

That's needed to see if your motherboard is stable with that FSB and those settings..

If it proves stable then all you need to do do be able to run 9x 400MHz FSB = 3.6GHz is more Vcore,as that holds you back..


CHEERS..

Also try lowering your FSB. I have the same mobo and it doesn't like high FSB (stock is 1.1v as opposed to some that are 1.2v). I think you also want to disable Dram Read Training. I'd check but I have to leave for work here in a min.

Thanks for the help guys. I've been busy for the past week and was not able to play around with the board. FSB and NB voltages have been lowered since they were not the cause of the problems. I have determined the problem.

Load Line Calibration being enabled was causing my computer to either BSOD or crash without any error message. Disabling it and upping the vCore to 1.5V results in a 1.44V idle and 1.36V load as reported by CPU-Z. Manually setting the vCore with LLC enabled to either or those voltages will cause the machine to crash when running LinX and Prime95(after awhile).

I have never seen this happen. Any ideas or does anyone know a pencil mod for this board? I've searched and have come up empty.
