So my 3Ghz OC wasn't posting at all anymore. I used the config from someone elses OC (same board, CPU, diff ram) and it posted without issue. I am worried about this. The part in bold is higher then what is set to auto and I am unsure of what they mean.
I know there are a few of them, but i just don't want to fry anything. My north bridge (Gold HS right below the CPU) is pretty darn hot, but not burning hot. Should this be an issue?

hi all. I found this thread when browsing google and thought I could help. I have the same MOBO and CPU and I also went through lots of anguish when I tried to OC the q8200 but I have some good news to those who have the DS3L MOBO + qQ8200 CPU: I found the rock solid values for 3Ghz. they were tested with prime95, intel burnin test, PCmark and 3dmark06. I had these settings rock solid while folding with the GPU and CPU 24/7 (100% load on all 4 cores and the video card) for the past month (its been on folding full blast since)
so here are the exact values in bios:
FSB: 429Mhz
PCI-E: 100Mhz
C.I.A: DISABLED
ADVANCED CLOCK CONTROL: 800mv
800mv
ops
0ps
SYSTEM MEMORY MULTIPLIER (SPD): 2.00B
MEM: 858Mhz
RAM TIMINGS: 5-5-5-15
ADVANCED RAM TIMING CONTROL: ALL AUTO EXCEPT tRFC IS 48 (DEF. 72)
CPU Vcore: 1.31250V (1.264 in CPU-Z because of V-drop)
CPU TERMINATION: 1.200V
CPU PLL: 1.650V
CPU REFERENCE: 0.762V
MCH CORE: 1.300V
MCH REFERENCE: 0.760V
ICH I/O: 1.550V
DRAM: 2.2V
ADVANCED BIOS FEATURES:
LIMIT CPUID MAX TO 3: DISABLED
NO EXECUTE MEM PROTECT: ENABLED
CPU ENHANCED HALT (C1E): DISABLED
CPU EIST FUNCTION: DISABLED
all the other values were untouched.
my RAM is different from yours, so the only thing that would make these settings not work with your setup if your RAM can't OC to 858Mhz. these settings underclock my RAM from 1066 but they allow for the 1:1 FSBRAM ratio.
the reason I was googleing this topic is because I know this chip can get to about 3.5Ghz and was looking for clues on what to adjust in BIOS to achieve that.
it seems your PSU is powerful enough to support this OC. the only question is the RAM but I think that should be OK too. good luck with your OC.
