The bios is some thing ive never messed with, ive heard i need to flash it or add micro codes but ive looked for hours and hours to find my bios online but i cant find it anywere? its a Pegatron IPIEL-LA board with AMI bios.
The closest ive found is this reference: sp44779 rom file EUR5.14 but i dont have the actual file

if you have board with AMI bios, why dont you try save your current bios, and add the microcode, then flash with it...
you can use afudos or afuwin to save your current bios...

So I did some reading for my particular board and managed to do the pencil volt mod. The vdroop is slightly better now. I mentioned before when I had it at 1.3 vcore in the bios, it went as low as 1.248 to 1.280 at load in CPU-Z. After this mod, it was around 1.280 to 1.296 at load. The vdrop however is still there with a differenceof about .3 from what it is set in the bios to idle.

So I attempted to keep raising the voltage. I got it all the way up to 1.4 in the bios which translates to around 1.360 or so at idle and 1.3248 at load. Intel Burn Test was still throwing errors at a 3.4 Ghz clock speed.

I think that this may be a bad overclocking chip. I mean, it does 3.3 Ghz at stock no problem, but a 100 Mhz increase and I'm having to increase the voltage to 1.4+? Who knows what I'd need for 3.5 Ghz+!

This mobo was fine with E8400 I had paired with it before. It managed 4.1 Ghz at 1.25 vcore which I thought was brilliant. Could have pushed it some more.

Such a shame because I heard these were good overclockers especially the E0 revision.

Nice work on the research and you got some results, albeit not exactly what you wanted. However, the conclusion you draw may be flawed.

Without bumping voltage at all, my X5470 was only able to do 3.6GHz on my P35 board but on my P45 board with LLC handled 4GHz just fine. I think to get the most out of your E xeon, you will need a better motherboard chipset that can provide better power delivery. In hindsight, the mod should have pointed out things like this, so as to not raise so much hope for people on P35 chipsets (like myself). I was determined to see a 4GHz LGA771/775 CPU though, so I ebay'ed my board and got a decent deal.

This is the setup I have right now:



So, now, guys, I am having all my voltage settings in bios on AUTO - question is, should I override them and replace it, i.e. set for vcore 1.3500 (that`s should be stock max vcore for X5460) for better stability?

I have been able to run all kind of synth tests on the auto settings, and was observing the vcore with hardware info going 1.32 and a little bit above.

If I am stable now, which I am, any benefit if setting custom settings?

When I have tried to set vcore to 1.3500 when priming I get over 1.3500 even 1.36 and on auto I get max 1.344... so better temps.
Unless your overclocking, theres zero poin't to increace your voltage back up to normal levels

yea i have that psychological barrier too, just need to be able to run 4.0 ghz stabile on quad biggrin.gif

Right now i have some offer to swap my Q9550 e0 for E5450 e0....hope that 0.5x more multi give me better OC, and less power consumption

i have a sensor problems . i think that the temps are not correct

Just to add some context to this, I have an X5470 running at 4Ghz stable on a P35 board (Asus P5K Deluxe). I just left the voltages on 'auto', bumped the FSB to 400 and locked the DRAM back down to stock.

The Asus P5K Deluxe is P35 but has LLC -- you didn't detail if you have it enabled or not. Even the non-deluxe version's LLC isn't working as reported by some google searches. Given your particular exception, it's still fair to say that P35 chipsets didn't commonly include mechanisms to eliminate VDroop, which became a large hindrance to overclocking without using absurdly high BIOS voltages in order to maintain necessary operating voltages on load.

The bios settings are all pretty much Default apart from the FSB.

In the BIOS the LLC option provided by ASUS is called 'CPU Voltage Damper', and from a glance at this documentation i would assume it's off by default (and therefore currently disabled in my BIOS):

Guys anyone run E5450 e0 on 4.0 ghz? what voltage i can expect for chip that was never OC'd on stock motherboard?
