Foxconn Quantum Force Black Ops X48 OC Guide (56k Warning)

Use my settings published above and you will be able to use not only FSB=400, but FSB=421 with x9.5 multiplier, your rig will be faster than with x10 and FSB=400.
Those settings are quite safe, and you can even lower the CPU V core voltage, I would say it should be fine at 1.36-1.38V (depending on the CPU) with Vdrop enabled.

Tried to use these fsb and multi settings BUT unable to boot after with error code 61. Tried to reset on mobo and also poer off PSU an reboot BUT kept getting the same error massage on the LCD. Finally had to reset cmos reboot again. Any other ideas.....i have tried to reduce cpu voltage below 1.40 BUT the system will not post. MY particular cpu needs 1.40 volts or more to boot into Vista at 400 x 10 or higher. I used to use nearly 1.60 volts on this cpu to get 4.0 stable on the Nvidia 790i ultra chipset !!
I guess every cpu is different.

Vdrroop compensdation enabled in bios?
1.6v for 4.0G is too much unless your cpu is really bad...

Vdroop compensation is enabled in BIOS. 1.6 volts was for NVIDIA 790i Ultra chipset. BUT on this mobo X48 chipset, i am using about 1.43-1.45 volts to get 4.05GHz stable hopefully.

I'll need to poke through the BIOS options then, as I just got this thing working Friday night at about 11 PM. Never heard of using a CD for BIOS updating.

Well, EVGA mostly uses CD *.iso images for BIOS updates on 790i and 780i. It is pretty easy to create a bootable CD using something like MagicISO and burn on it awdflash and actual bin BIOS file for Blackops as well.

First off, not trying to chase your posts. Can you clarify something for me? I was under the impression that the ROM1 and ROM2 feature only worked for settings saving [Gear Store 1-8]; so by your comment, am I correct in gathering that the BIOS actually stores itself as well on both chips?

http://www.quantum-force.net/news/N000000016/
"whilst the new Twin BIOS feature safeguards against BIOS corruption and enables hot-swapping of BIOS chips."
Take a look at this picture:


We can see those two BIOS hot-swaping (located on panels) BIOS memory chips. Also one can force to use one of two BIOSes with jumpers.
This feature is a HUGE plus to Foxconn engineering approach IMO. If one's BIOS is corrupt, he/she doesn't need to RMA the whole MB, one can use another chip while waiting for the second chip replacement, which can be just plugged into the panel, no soldering required.

And yes, AFAIK you can record different versions of BIOS on two chips separately. Take a look on your Live update panel.

I'll give it a go and see what happens....where are you settings published? Can you provide a link as there are now over 400 posts in this thread.

Hmm, this is quite interesting. Let me think a bit.
Could you re-check all your voltage settings please, and re-connect your memory and power connectors to be sure that they are fixed in the positions?

Yep checked all the connections...all OK. I now can boot into Vista 32 bit at 4040 MHz with cpu voltage of 1.45 in the BIOS. VDroop enebled. All the memory timing are set at 7-7-7-20 at 1T with memory voltage of 1.875 or something along those lines...BIOS however reads memory voltage at 1.91 after reboot. Other memory setting mostly all on auto except command dll, controll dll and clock dll at -2. NB voltage ts 1.564. SB is at 1.50. FSB 405 x 10. All other cpu settings are as i had posted earlier except GTL ref voltage which are now at default. Have not run any benchmarks just yet.
Will keep you guys posted about stability later.

Well, due to some friggin' strange reason, the 92mm x 38mm fan on my CoolIT Freezone died yesterday and now it is forcing me to lower my frequency . Might have to run the system with 500FSB but with 4Ghz speed until I get a replacement fan. I will post images of stability testing and some settings when I see that it is at least SuperPI 32M stable. I guess I got to say goodbye to 4M test under 1min and 32M under 11min .
