I
always test 'em 'one-at-a-time',
prior to ever putting any more in the board at once... Procedure is in:
Memory - Part IV - "Tweaking and tuning"
Have done a few successfull OC's for P43's here - don't have one for that exact board, but shouldn't be much to modify - likely take less than a half-hour... Here's a sample:
A lot of this is 'canned' - so if you've seen parts of it before, skip ahead!
GA-EP43-UD3L E4500 to 2.93 GHz
Intel E6300 1066FSB x10.5mult 2.8GHz .85-1.3625V Core R0 sSpec SLGU9 CPUID 1067Ah
Crucial CT2KIT25664AA800 R 4GB (2 x 2GB) 240-Pin SDRAM DDR2 800 memory: 6-6-6-?? nominal 1.8v
Gentle (but noticeable), no-risk, low-voltage Overclocking parameters (assuming anything
but stock HSF...) are in
italics...
If you haven't yet done it, pull out all but one stick, start with a BIOS' "Load Optimized Defaults"
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"
"C2/C2E State Support" to "Disabled"
"CPU Thermal Monitor 2 (TM2)" to "Enabled"
"CPU EIST Function" to "Disabled"
"Virtualization Technology" to "Enabled" - this allows use of Win7's fantastic VirtualXp feature...
"Full Screen LOGO Show" to "Disabled"
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 whichever OS type you're running - "32-bit" if an x86 version, "64-bit" if an x64 version...
On the "MB Intelligent Tweaker(M.I.T.)" page:
"Robust Graphics Booster" to "Auto"
"CPU Clock Ratio" to "10"
"Fine CPU Clock Ratio" to ".5"
"CPU Frequency" - this one can't be set, it's calculated, and will change when we set the next few items...
******** Clock Chip Control ********
>>>>> Standard Clock Control
"CPU Host Clock Control" to "Enabled"
"CPU Host Frequency (Mhz)" to "267"
"CPU Host Frequency (Mhz)" to "334"
"PCI Express Frequency (Mhz)" to "100" (not auto...)
"C.I.A.2" to "Disabled"
******** DRAM Performance Control ********
"Performance Enhance" to "Standard"
"(G)MCH Frequency Latch" to "266"
"(G)MCH Frequency Latch" to "333"
"System Memory Multiplier (SPD)" to "3.0 A"
"System Memory Multiplier (SPD)" to "2.4 B"
"Memory Frequency (Mhz)" - again, can't be set, it's calculated...
"DRAM Timing Selectable (SPD)" to "Manual"
You should be able to leave the rest of the memory settings alone; we haven't changed its actual speed, so the "LoadOpt" settings should keep working...
"Load-Line Calibration" to "Disabled" (this works differently on different boards - on mine, it's worse "enabled" than "disabled" - the function is supposed to cure a phenomenon called Vdroop - the CPU voltage regulation circuit causes the CPU core voltage to sag, or 'droop' under high loadings; hopefully, we're going to be at a low enough voltage to just ignore this...)
"CPU Vcore" to "1.2500V"
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!
