First off to set the record straight, I'm a newb to OC'ing so please forgive me if I'm asking redundant questions and also for the long post, trying to give and get as much info as possible..
Current setup:
Processor: Q6600 GO 2.40ghz <- Currently running @ 2.70ghz
MOBO: Striker Extreme <- Running BIOS 1305
RAM: 4GB Corsair XMS2 6400 RAM (4 x 1GB Sticks = 2 x matched pairs) <- Timings @ 4-4-4-12 / 2T
GPU: 2 x 7900 GTX in SLI
HDD: 70GB WDRaptor
PSU: 650 Watt Enermax
Case: Antec P180
Windows Vista 32Bit (yeah I know, why 4GB RAM... Because I'm a newb ofc!)
Reasonable air cooling, but the processor currently has the stock Intel cooler. I did buy an Arctic Freezer 7 Pro, but had "clearance issues" when fitting (DOH!).
Testing Programs Used: CoreTemp & Orthos (2 instances out of separate folders)
This all runs fine at stock settings, but the reason I spent the cash on this was with OC'ing in mind. Been doing lots of research around various websites and have started to try it. However, I've come up against a problem that I cannot seem to resolve and was hoping to get some advice from those with a little more experience.
Using the settings below I am currently running at a stable 2.70ghz, tested over a few hours. However, I cannot push the FSB past 1205. Any higher and the system has difficulty posting, never mind getting to Windows. Something strange though, when it does post and I manage to get into the BIOS and look at the processor speed from the OC page; it reads the stock speed of 2.40ghz, even though the FSB is set above 1200 and should be running above 2.70ghz. I thought this may have something to do with the BIOS ignoring my FSB setting due to the trouble posting, any comment if this is normal?
I've read on a few sites that the board doesn't like OC'ing with 4GB RAM so took 2 sticks out, but it didn't make any difference. I've also run memtest86+ for a few hours on all 4 sticks and no reported errors.
Here are my current BIOS settings:
AI Tuning: Manual
Nvidia GPU Ex: Disabled
LinkBoost: Disabled
FSB - Memory Clock Mode: Unlinked
FSB (QDR), Mhz: 1200 -> tried various settings between 1200 up to 1333
MEM (DDR), Mhz: 800 -> Haven't moved this at all whilst OC'ing
Vcore Voltage:1.150 -> took this to 1.425 but still same problem
Memory Voltage: 1.950 -> took this to 2.2 but still same problem
1.2v HT Voltage: 1.20 -> took this to 1.35 but still same problem
NB Core Voltage: 1.20 -> took this to 1.40 but still same problem
SB Core Voltage: 1.50 -> took this to 1.5 but still same problem
CPU VTT Voltage: 1.20 -> took this to 1.35 but still same problem
*NOTE* Voltage changes were tried incrementally from what appearred to be stock, in a linked fashion ie. All moved 1 increment and then re-tried (until I got bored and just bumped them up as far as I dared). As above, this made no difference to the post problem, so I've now lowered them and the system still runs stable for over an hour testing on Orthos.
CPU Multi: 9x (Max value that Intel allow on these chips... ?)
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled
MCP PCIE Spread Spectrum: Disabled
SATA Spread Spectrum: Disabled
LDT Spread Spectrum: Disabled
CPU Internal Thermal Control: Disabled
Limit CPUID MaxVal: Disabled
Enhanced C1 (C1E): Disabled
Execute Disable Bit: Disabled
Virtualization Technology: Disabled
Enhanced Intel Speedstep Tech: Disabled
LDT Frequency: 5x
PCIEX16_1 Frequency (Mhz): 100
PCIEX16_2 Frequency (Mhz): 100
PCIEX16_3 Frequency (Mhz): 100
SPP<->MCP Ref Clock, Mhz: 200
Temperatures Idle & Load:
44 - 43 - 44 - 40
55 - 55 - 49 - 48
PHEW! Loooong post, but if you got this far, thanks for reading and thanks in advance for any advice.
P.S Merry Xmas too
