I have 2.1v going to the ram...
I would have thought that going from 8 to 8.5 would be entirely down to the CPU... But I'm curious: what temps are you getting on IBT when you test 8x471?
68ºC on the first core, 64ºC on the remaining three. Prime is around 61/58 - 42/39 idle.
My lack of stability at 6x480 still points me to a limitation elsewhere than the cpu. Perhaps I'm hitting this board's limits with the memory speed with all 4 banks filled with 2GB sticks...
I figure the next step is to go for 3.9Ghz tomorrow and see if it works or if any voltages need to skyrocket.
Apparently I can all of a sudden lower my NB/VTT down to nothing at 3.8GHz. My best stable 3.8GHz settings:
CPU Ratio Setting: 8.5
FSB Strap to North Bridge: 333MHz
FSB Frequency: 447
PCIE Frequency: 100
DRAM Frequency: 894MHz
DRAM Timing Control: Set to 5-5-5-15
CPU Voltage: 1.1875v (1.160v actual)

CPU Voltage Damper: ENABLED
PLL Voltage: 1.56v
DRAM Voltage: 2.1v
FSB Termination Voltage: 1.2v
North Bridge Voltage: 1.25v
North Bridge Voltage Reference: 0.67x
South Bridge Voltage: Auto

Asus R2G.
Eh, I'll wait for a non-SLI motherboard and an i7 refresh (die shrink or 8 core). That or if MS CashBack shoots up ever again. There isn't any use to move up to i7 besides "bragging rights" at the moment or if every split second matters when encoding. It just makes no sense why I can't bump this cpu up any further. I am going to search for a larger (ATX spec dimensioned, not any of this 6" deep crap!) power supply.
Antec EA380 - I'm near its limits with such a system but I had it all running fine in a Shuttle with a 300w power supply so the Antec should be more than enough.

you know the french thread?
thanks, i'll do the mod tomorrow morning then, if anyone has bios settings for me to get around 3.2-3.4ghz and max my ram or close, its rated 5 5 5 18 1000mhz 2.1volts max would be much appreciated (i guess just change the settings i have here) and if you can tell me how much of each volts not to go over, i know cpu shouldnt go over 1.5 and my ram shouldnt go over 2.1

sorry NichoTL didnt see your post, but what would you change of yours for i guess 3.4ghz if its not too hard to get, my hsf seems to cool well
To what do these need to be set and what shouldn't they be set ? Also, can you explain what they do ?Like I said in my previous post, ditch the Auto settings for Strap, NB, PLL, FSB and DRAM voltage at least.

I brought the FSB and NB voltage down to 1.28v and 1.35v respectively, to achieve 500MHz FSB stable under Prime95, it successfully did 5 runs while I'm typing so that's about right. Now I can enjoy getting the processor up... But I won't be able to stresstest much, the temps at the moment are about 85-90°C under full load, the Stock Intel cooler doesn't like it... I did disable C1E and TM Function, what I've read this should help keep the overclocked CPU stable.
About PLL and Vdroop, what I've read on various forums is that it's not advised to alter the default settings as it could drastically reduce the lifetime of your components. And I don't want a fried CPU in 2 months I'm not looking for extreme overclocking here anyway, I'm happy I reached 500MHz FSB and now I hope I can get 3.5GHz on the CPU.
EDIT: I can get 3.5GHz (500MHz x 7) stable, but it's going to be at 1.57 or higher vCore. Since I'm still running the standard Intel cooler which already reaches 95-98°C under 50% load, I'm not going to stresstest it. I tried changing the CPU Reference to any setting but it didn't help. 1.57v and above seem pretty dangerous, certainly as most of the time it will be idling at that voltage.
I gave 533MHz another shot but even with PLL voltage 1.6v, FSB 1.5v, NB 1.6v and NB Reference at 0.67x it didn't POST. So I guess this seems to be the sweet spot. I think for gaming and Photoshop it's more useful to run at 3.0GHz with 500MHz FSB with the memory at 1000MHz (1:1) than to run 3.7GHz at 333MHz FSB and the memory at 1066MHz. Now I'll need to see for a decent chipset cooler...
