trying to get 2800mhz stable NB with 1866mhz Ram
2600mhz was even unstable with 1.4v NB. I can get 2600mhz to post with 1.2v NB but i have to raise NB core to 1.1625v or crash on window splash screen
Current setup Win7Prox64:
4.72ghz 8Core, 200.9BUS, 2611mhz HT link
Gigabyte FX990-Gaming+GTX1080 OC 2100mhz
9590 stock settings but strangely runs at 200.9 mhz in auto instead of 200, not sure if my 8350 did this
2600mhz CPU-NB 1.25v - NB core 1.625v
1866mhz 8-9-9-24 2t 1.6v 8gbx2 DualRank RAM posts and the RAM runs fine at all speeds, i am using XMP
HT link is auto(2600mhz) im cool with that.
H115i cooling
G. skill turbulence 2
EVGA G3, low noise and ripple 1000w
Pure Sine Wave AVR & UPS for clean power, brown outs cause crashes and can damage chips
Problem is 2800mhz, I am seeing best posts with 1.3-1.4v on the NB but i needed to boost NB core to 1.15 to get to desktop and 1.16 to be stable in games. what are safe NB core volts?
I got this info for volts and speeds from AMD tuning guide, says safe NB volts are up to 1.55v but some head room for better cooling, no mention of NB Core though
CPU NB Voltage 1.35v-1.45v(air cool) 1.4v-1.65v(*extreme)
CPU NB Clock 2500-2700mhz(air cooled) 3700-4200mhz(*extreme)
*For CPU NB volts I think 1.65v(extreme) is for LN2 and 1.55v is max for Water cool, while 1.45v is highest for air cooled
Any ideas on how to get 2800mhz on FX AMD to match a 1866mhz RAM overclock, whats voltages are you guys getting on your CPU-NB and NB core @2800mhz. NB core i believe is the north bridge chip itself
