Gear used:
E6320 with Scythe Ninja Plus using 120mm scythe fan and a zalman 92mm fan assisting on the opposite side (push - pull)
Asus P5K-Deluxe - All motherboard chipset voltages manually set to the lowest available
2x1GB Crucial Ballistix PC2-5300 3-3-3 2.2v with 2x60mm fans attached to the top. Ram set to manual timings 5-5-5-11, rest auto

Only testing with E6320 L707A335 <-- severely fsb wall limited by 480FSB
Max CPU frequency for testing is about 470. I gave 501FSB a shot via bios, but no luck. This seems common for some E6320's. SS has 1.45v written which is correct, but I later found it to be unstable so 1.475v is testing right now. There is a vdrop from BIOS setting though so it's at least 30mV less than set in BIOS.


Max stable cpu found (for short testing) so now onto RAM. 600MHz / DDR2-1200 was achievable for windows booting (not stable for 24/7) with only 2.25 or so volts. This got me wanting to find the max RAM clocks.........2.55v

Screen shot is one thing, validation is another
I would like to get 700MHz screen or even valid, but it's a bit hard. Maybe on a cold morning

I'd like to say more to come, but all I plan on doing now is find a nice 24/7 stable and safe setting till I get my Xeon 3070 back.

General info/findings:
- Original bios sucks for OC recovery. I have found the 0304 BIOS excellent for recovery from failed OC's or just bad settings. Just turn off the psu from the back (or unplug power), plug/turn back on and all good. No settings lost, just a safe mode to open BIOS and re-tweak
- This board seems to be able to hit high FSB with very low voltage. I tried to add all sorts of volts but I am unable to pass 480FSB, and can't even get 6x480FSB stable let alone 7x480. damn fsb wall
- I am using the voltage damper option and vdrop according to Asus probe II from idle to load is ~10mV!
- The motherboard doesn't read temps identical to coretemp. When I first booted the board it said 12C. Coretemp said something like 18C (nice ambient temps oh yeah). Then under full load motherboard was reporting 4-5C hotter than coretemp.
- So many RAM ratio's to choose from, I only tried 4:5, 2:3 seriously and both seemed fine at DDR2-1200.

Trying for some RAM settings without the need to have a fan over the memory. 2.05v on the RAM, DDR2-1128 (loose 5-5-5 timings though), still testing.

Ambient temps are low and mobo temps aren't too bad as a result. I don't have any fans specifically helping NB though.

edit: those were stable for overnight but when I rebooted from windows it crashed before loading BIOS! I just bumped vcore from 1.475 to 1.4825 and I'll see how that goes.

It didn't need more vcore or vdimm, it needed more nb voltage! bumped it up to 1.40v and no problems rebooting now.

32M PI at my attempted 24/7 settings:

OMG that's ****ing nuts (RAM speed)

You aint seen nothing yet I got the magic number this morning
DDR2-1400 On my $190AUD inc delivery Crucial Ballistix PC2-5300 RAM

That's DDR2-1350 Dual channel booting to windows and DDR2-1400 single 1GB stick using setfsb after booting from DDR2-1367

I've been playing the super PI game a bit today, a bit limited with this CPU and RAM can't do 4-4-4 timings much higher than DDR2 1050 I think. So low clock 32M Super PI, I was aiming for sub 15min around 3.05GHz, didn't quite make it even with most subtimings relatively tight




Then here are my 24/7 settings that I orthos'd last night. 470FSB x 7 multi. RAM with 5:6 divider set to 5-5-5-8, rest set to auto but 35 TRFC.

nice overclock

my 24/7 clocks on ram are similar but mine don't clock that high with more volts

i run my rig 367*10=3670 1.36v 550MHz on RAM 2.2v 5-5-5-x (OEM Micron sticks....cheap too heh)

Dice

Hopefully I can get something like that going when I get my Xeon 3070 back from RMA. My RAM is only getting 2.05v atm at DDR2-1128. I can't imagine what the PC2-8000 and PC2-8500 Crucial kits will manage! They gain the ability to do 4-4-4 timings at DDR2-1100+ clocks I think.

dinos22

i think you got very lucky

my PC10000 don't do that.........errr i haven't tried but they would probably struggle
