Haven't forgotten about you! Just had a hellacious day, and, like I said - I'm NUTS! Manic-depressive, naturally insomniac, and missing sleep causes mania, which causes mor insomnia, leading to more mania - and pretty soon, I'm wandering around the ceiling with my tinfoil hat on!
Part of your trouble is that you are running four DIMMs - the parameter sets stored inside the DIMM itself, the SPD data, is optimized for two DIMMs, particularly one DIMM channel - using more takes a couple adjustments...
If you aren't now at BIOS F12, download it
here, and flash before starting - as I say, the 'C' chipsets are
already somewhat 'unstable' - we need all the help we can get! DON'T use @BIOS!
A lot of this is 'canned' - so if you've seen parts of it before, skip ahead!
GA-P35C-DS3R E6850 to 3 or 3.6 GHz
Intel E6850 1333FSB x9.0mult 3.0GHz .85-1.5V Core G0 sSpec SLACR CPUID 06FBh
Patriot Memory PDC22G6400LLK ?GB (? x 2GB) 240-Pin DDR2 SDRAM DDR2 1200 memory: 5-5-5-18-2t nominal 2.1-2.2v
Gentle (but noticeable), no-risk, low-voltage Overclocking parameters are in
italics...
If you haven't yet done it, pull out all but one DIMM, start with a BIOS' "Load Optimized Defaults" to set sub-timings...
Before we start ramping things up, I want to teach you a new skill involving the BIOS: Do the <DEL> at the boot to enter the BIOS;
notice, at the bottom, the <F11> "Save CMOS to BIOS" - hit this, and you should get a menu that will show a number (the count varies by BIOS) of empty 'slots', each of which will store an entire set of BIOS parameters, to be re-loaded from the corresponding <F12> "Load CMOS from BIOS"; this is a wonderful overclocker's feature. What I do with it, is to save my 'baseline' working parameters, so if I change something that 'irritates' the board, and forces a reset of all the parameters to defaults, or, even worse, get so screwed up I need to do a 'clear CMOS', I can get back to my starting point with no effort, and without having to remember 85 separate settings! Another thing it prevents is two hours' troubleshooting, having forgotten a change to a crucial parameter - like, "wait a minute - didn't I have the Trd at seven?!" It's pretty self-explanatory, and I alway urge people to start right away by taking the time to give the 'slots' names that mean something: in two hours, "Try2" and "Try3" will not be very helpful, but "450@+10MCH" and "450@+15MCH" will! Another use is for 'green' settings; overclocks, as a rule, do not 'play well' with green features, such as 'down-clocking' and 'down-volting'; with the storage slots, you can set up one profile, say "Green", with all the settings at 'stock' values, and all the 'green' features enabled; another, say "Balls2Wall" with a full overclock, and all the 'green' stuff turned off... Another neat feature of this 'slot' system is, for most BIOS, the mechanism itself will keep track of which ones have booted successfully, and how many times (up to, I believe, a max of five)!
On the "Advanced BIOS Features" page:
"CPU Enhanced Halt (C1E)" to "Disabled"
"CPU Thermal Monitor 2 (TM2)" to "Enabled"
"CPU EIST Function" to "Disabled"
"Full Screen LOGO Show" to "Disabled" (for convenience in entering BIOS)
On the "Integrated Peripherals" page:
Your manual shows "Legacy USB storage detect", but later BIOS say "USB Storage Function" - either way, set to "Disabled"
On the "Power Management Setup" page:
"ACPI Suspend Type" to "S1(POS)" (for now...)
"HPET Support" to "Enabled"
"HPET Mode" to "64-bit"
Do the <CTRL>+<F1> to 'unlock'; on the "PnP/PCI Configurations" page:
(if it appears at all...)"PCI Latency" to "64"
On the "MB Intelligent Tweaker(M.I.T.)" page:
"Robust Graphics Booster" to "Auto"
"CPU Clock Ratio" to "9X"
"CPU Frequency" - this one can't be set, it's calculated, and will change when we set the next few items...
"CPU Host Clock Control" to "Enabled"
"CPU Host Frequency (Mhz)" to "334"
"CPU Host Frequency (Mhz)" to "401"
"PCI Express Frequency (Mhz)" to "100" (
not auto...)
"C.I.A.2" to "Disabled"
"Performance Enhance" to "Standard"
"System Memory Multiplier (SPD)" to "2.40 B"
"System Memory Multiplier (SPD)" to "2.00 D"
"Memory Frequency (Mhz)" - again, can't be set, it's calculated...
"DRAM Timing Selectable (SPD)" to "Manual"
******** Standard Timing Control ********
Most of the memory timings should be good in "Auto", as set by the LoadOpt...
if "Static tRead Value" wasn't set to
at least "7" by the "Load Opt", bump it up to there...
make sure "Command Rate(CMD)" is set to "2T"
whatever tRFC is set to, raise it by 15%, rounded
up to the next integer...
...rest of the sub-timings should be good...
"System Voltage Control to "Manual"
"DDR2 OverVoltage Control" to "+0.40V" ...you may be able to lower to .3 later...
"(G)MCH OverVoltage Control" to "+0.15V" ...for more than two sticks of ram...
"CPU Voltage Control to "Normal"
"CPU Voltage Control to "1.3500V"
And that should do it!
I should point out that getting two reboots in a row here is perfectly normal behavior; it seems that, when you change certain settings (and we don't exactly know which ones - the only sure one I know is Trd - if you change it, I think you get the 'twin' reboot) it boots once to 'see where it's at', recalculates its remaining 'auto' settings, saves them, and then boots again. Three reboots in a row, however, usually indicates that the board was 'given indigestion' by your settings, and is going back to defaults. This sometimes goes astray, and it doesn't get back into proper operation - for example, at this point, mine will sometimes 'lock' itself into 111MHz x a six multiplier - and take a week to do a whole boot - that's time to do a CMOS reset, and use your 'stored' <F12> profile to get back to where you were...
Good luck!
Bill
