InCrYsIs Posted October 19, 2011 Posted October 19, 2011 In general the P series boards WERE better overclockers Crysis - post up your current BIOS settings and I'll have a look. Current as in stock? or the layout of the Tweaker? Share this post Link to post Share on other sites More sharing options...

Now the chip and RAM have changed since this. I later found out my PSU was bad which was probably stoping this from working. Chip is now the 9650 and the RAM are 4X 2GB Sticks of Gskill Ripjaws 9-9-9-24-2N 1.5v according to specs. These aren't the current BIOS settings.

wevsspot Posted October 20, 2011 Posted October 20, 2011 Thanks Crysis. Here are my recommendations; CPU Clock Ratio = 9 CPU Host Frequency = 450 Memory Divider = 3:5 (this should yield an effective memory frequency of 1500Mhz) PCE Express Frequency = 102 *****Advanced Timing Control***** Refresh to Act Delay = leave at 60 Static tRead Value = leave at 8 Everything else should be good on Auto *****System Voltage Control***** DDR3 Overvoltage - shouldn't need to overvolt so set at factory specified voltage for your memory PCIe Overvoltage Control = +.1v FSB Overvoltage Control = +.2v (G)MCH Overvoltage Control = .15v CPU Voltage Control = 1.38v Everything else should be fine on Auto voltage settings It these recommendations don't work - you might consider shooting ccokeman a PM because he worked with this exact board for a review back in May, 2008.

Hyper Posted October 20, 2011 Posted October 20, 2011 2 or a little lower. Try to keep your ram around it's recamended speed or lower while oc'ing.. once you get to where you want your cpu then work on bumping the ram.. Share this post Link to post Share on other sites More sharing options...
wevsspot Posted October 20, 2011 Posted October 20, 2011 I'd try the 4.00B strap/divider to start with. Additionally, instead of jumping right to 450FSB I'd probably start at 400FSB and work my way up from there. Just food for thought. If the previous recommendations don't work try this; Robust Graphics Booster Auto CPU Clock Ratio 9 CPU Frequency 450FSB CPU Host Clock Control Enabled CPU Host Frequency (MHz) 450 PCI Express Frequency (MHz) 100 C.I.A.2 Disabled Performance Enhanced With Standard System Memory Multiplier 4.00B DRAM Timing Selectable Manual CAS Latency Time 8 DRAM RAS# to CAS# Delay 8 DRAM RAS# Precharge 8 Precharge delay (tRAS) 24 ACT to ACT Delay (tRRD) 4 Rank Write To READ Delay 8 Write To Precharge Delay 12 Refresh to ACT Delay 60 Read to Precharge Delay 6 Static tRead Value 8 Static tRead Phase Adjust Auto Command Rate 1N CPU/PCIEX Clock Driving 800mV CPU Clock Skew Control Normal (G)MCH Clock Skew Control Normal System Voltage Control Manual DDR3 Overvoltage Control Normal PCI-E Overvoltage Control + .10v FSB Overvoltage Control + .30v (G)MCH Overvoltage Control + .25v Loadline Calibration Disabled CPU Voltage Control 1.38v Share this post Link to post Share on other sites More sharing options...

wevsspot Posted October 21, 2011 Posted October 21, 2011 Well, at least it recovered All joking aside though, are you running the latest BIOS revision for the board? If so, go ahead and clear/reset your CMOS. Boot and load optimized defaults. Then change everything I noted above EXCEPT for the strap/memory divider and primary/secondary memory timings. Leave all of those on auto and see if you can get a boot. Check your motherboard monitor and see what voltage it says is going to your RAM at Auto settings. Please let me know.

wevsspot Posted October 21, 2011 Posted October 21, 2011 Ok. Let us know how it goes. My biggest challenge when o/c the LGA775 platform was getting the correct memory strap/divider chosen. That always seemed to be trial and error. Technically (according to the m/b manufacturer's) a good BIOS should be able to auto set those for you depending on the EPROM speed detected on the installed memory and the manually selected FSB on the motherboard. Guess we'll see how well your board does on that front With that being said, all of the other settings I provided should be right on target based on my experience. So the only offender HAS to be the memory strap/divider. Share this post Link to post Share on other sites More sharing options...

MB report DDRV 1.728 Okay FSB 450 and left all memory at auto. Memory is at 1800. Can the memory take that? I am in windows now with all the settings you posted. Running prime temps around 70c idle around 45. I manually rebooted and the OC failed again. Also fails at 400 fsb.

wevsspot Posted October 23, 2011 Posted October 23, 2011 Hmmm - that is really strange. I don't know if your memory can take 1800Mhz - that could be one of the problems. At auto settings your BIOS is WAY over-volting your memory, so I'd recommend taking the DRAM voltage off of auto and manually inputing the correct voltage as specified by G.Skill for your particular kit of RAM. Also, play around with the FSB and various memory straps/dividers and see if you can hit one that agrees with running your effective RAM frequency near or even a little below 1600Mhz. I used to have a cheat sheet for FSB versus memory strap/divider on the LGA775 socket, but can't find it for the world of me If you keep all of the same settings that got you into Windows at 450FSB, changing only cpu multiplier to x8 and memory strap/divider to 3.20b what happens? And what is your effective memory frequency then? Share this post Link to post Share on other sites More sharing options...
