Hey guys, I recently installed a new mobo and I had to start my oc from scarth. I was previously runnung stable at 4.7ghz but I have been running into multiple issues this time around. I have an ASRock 990FX Fatal1ty board, and was able to get things stable on Prime95 for over 4 hours at 4.6ghz with 1.435v and LLC disabled (so seeing Vcore spikes to 1.52v or so). After doing some research about the LLC on my board I've been trying to run with 25% LLC so that I don't see so much Vcore fluctuation, which has worked, keeps my Vcore around .10-.20 of where it is on bios. No Vdroop as well. I've given the cpu 1.45v which jumps to 1.47 in Prime95 when at 4.7ghz, my oc settings in bios are:
As a sidenote I ran memtest86 last night, 8 passes in 7 hours, no errors. All Power Consumption and saving options are off, I've gone throught everything. PCI Spread Spectrum disabled, turbo core disabled, app power management disabled. Ram timings are set to a manual profile. XMP 1.3 for the Patriot Viper 3 series.
CPU FSB=210mhz
CPU Multiplier=22.5x
HT and NB=2310mhz each
CPU/NB VID=1.2v Should I increase this? Considering HT and Northbridge frequencies are upped?
VID=1.4500v
VCore=1.4500v in bios jumping to 1.47 in Prime95
LLC=25% (Auto, 25%, 50%, 75%, 100%)
Ram Voltage: 1.51v
NB and all other voltages are set to auto.
Also, when LLC was put higher than 25% I noticed undervoltage and the pc wouldn't always boot.
I'm getting Illegal Sumouts in Prime95 as well without voltage upping itself to stay stable, which leads me to believe I may need to be tweaking something other than Vcore right now. Thanks for the help!
