Cool, I'll try it tonight.

[AMD666]

Flashed, so far it's working good, no issues.

[dnottis]

Flashed!

[Gen]

anyone have benchmarks/results from this bios so far compared to older bios'? (other than "it's good") or any reason at all to flash from 1012 besides new cpu support?

[Isira]

1013 seems to be as stable as 1006 for me. I don't have any instability issues that I had with 1012.

[JTeg86]

Ive got my E8400 @ 4Ghz. It will be bench stable 4Ghz @ only 1.272V. It is Orthos stable at 1.3V

I am running 9 x 445 right now.

However I cannot run 500 x 8.

Is there any other setting I need to change in BIOS? I want to be able to get the max OC I can and still run my memory at/near DDR2-1066 The only settings that I have changed is:
CPU: 9
FSB: 445
CPU Voltage: 1.3
RAM Voltage: 2.2V

Every other setting is set to 'Auto' Im still new to Intel OC'in so bear with me. I did disable the C1e support.

I also know for a fact that my Corsair XMS2 will do DDR1066.

Thanks all

thanks.

*snip*

did you disable spread spectrums? how much cpu pll are you running? have you tried playing with all cpu or nb gtl references at 1.3v (or try up to 1.32v +references)?

[JTeg86]

How much PLL voltage should I give it?

I just changed NB to 1.55V and SB to 1.2V

[Gen]

start from lowest and find out

i wouldn't go higher than 1.5v for 24/7 tho

[JTeg86]

I do not see CPU Voltage Damper in BIOS I currently have BIOS 1012 flashed, was this eliminated in this BIOS? Also is there any advanced options in this bios?

Look for Load Line Calibration.

[CrazyNutz]

I just changed NB to 1.55V and SB to 1.2V

I have not seen a need for more than the standard PLL 1.50v on my cpus,
and I've had them up past 500mhz FSB, no probems. Just FYI you dont need to increse PLL just becuase you raised the NB & SB voltage.

[JTeg86]

Ok, I did some more playing around today with the E8400

I can reach 8 x 500 but anything over that is not stable. Im pretty sure I have hit the FSB wall at 500 which is kind of dissappointing.

The highest my E8400 could do was 4.4Ghz @ 1.39V I did not want to push it any higher on air.

Right now im running @ 4.2Ghz (8.5 x 495) stable 1.36V

Is there anything else I can do to get it over 500FSB? I want to be able to run my memory near 1066 for max perf. I had these settings:

NB: 1.55V
SB: 1.2V
FSB Term: 1.1V
PLL: 1.5V

Load Line cal.: ENABLED
Spread spectrums: DISABLED
Transaction Booster: DISABLED

I even tried manually setting memory to 1:1
Disabled everything but execute last bit.

I know for a fact my XMS2 will do DDR2-1066. How about a different Bios?

Except 1.5V PLL in BIOS is NOT 1.5V actual:

eheh thanks

This is the table of VoltBugs:

BIOS ALL

VMCH BUG
Bios ---------------- Tester

1,25v(or AUTO) --- 1,55v
1,40v -------------- 1,40v
1,55v -------------- 1,55v
1,70v -------------- 1,70v


VPLL BUG
Bios ---------------- Tester

1,5v(or AUTO) --- 1,8v
1,6v -------------- 1,6v
1,7v -------------- 1,7v
1,8v -------------- 1,8v


VFSB BUG
Bios ---------------- Tester

1,2v(or AUTO) --- 1,4v
1,3v -------------- 1,3v
1,4v -------------- 1,4v
1,5v -------------- 1,5v


vSB & vDIMM works fine!

All P5K-E owners (maybe other Asus M/B's as well) should keep this in mind because they may be running much higher voltage levels than they think they are. I have taken DMM measurements to confirm the above findings.

[qujck]

why does nobody use the 1004 Bios?
I'm running 8x530Mhz FSB with 1,7NB V and it there are no issues.
And for the Temps, the NB cooler and the mosfets are not more than hand warm!!
But i'm using a 120mm fan for NB and RAM.

My Settings:

CPUV : 1,3125( Bios ) 1,28V Windows
PLL V: 1,70V
FSB T V: 1,2V
DRAM: 2,3V
NB: 1,7V
SB: 1,05V
Clock over: Auto
CPU GTL: 0,57
NB GTL: 0,61

8x530Mhz 4240MHz

Is it stable orthoss large fft or blend ?

I don't believe this bug

[qujck]

it is fully prime small FFT's (8-40K's) and Large FFT's (448-1024K's) 3 hrs stable, each.

I don't believe this bug

It's not about believing or not believing...all you need to do is set your volts for Vpll, Vmch, Vtt to the lowest level in BIOS and take actual measurements with a voltmeter.

Measurement points can be found here and here.

Hey, maybe it's a bug that only affect a few select motherboards, but I tend to doubt that. I'm only pointing this out because it's a significant bug that can potentially affect the life expectancy of your CPU - what with reports of high Vtt and Vpll frying or degrading chips.

Don't you wonder why so many people find the "lowest" settings to give the best OC on these boards?

[Plester]

I just confirmed the bogus voltages - as syl said this is a big deal, especially the Vpll - mine is at 1.84v when set to either Auto or 1.55v. I also have a Vmem bug where Auto = 2.05v (my lowly XMS ddr667 was really impressing me making it up to 950 with allegedly only 1.8v - now I get why when I would change Vmem from Auto to 1.85 or 1.9v I would BSOD on bootup).

Aside from smoking/degrading cpus and mobos, this makes overclocking a real challenge when you have the illusion of voltage controls. I wonder how many other models of Asus and/or other manufacturers suffer from this and why Asus lets it happen - their engineers can't be that out-to-lunch. Pretty f...ed up stuff, I am glad I read this - might be worth spreading the word and making a sticky post with this info...

[Isira]

It's quite disturbing when you find out the lowest voltage does not equate to the lowest voltage.

Based on the table, I guess the best recommended voltages to start out with are:
Northbridge = 1.4V
CPU PLL = 1.6V
FSB Termination = 1.3V

the "voltbug", there is on more of p5k's family: p5k, p5k-e, p5k pro....

As I suspected and a big thanks for bringing forth this issue originally BarboneNet

The question we should all ask is is this truly a "bug" or is it some engineering slight-of-hand to fool the consumer into thinking they have a kick-a** board that is able to do more with less.

This is a great M/B with some of the steadiest voltages I've seen, but as Plester mentioned, the voltage adjustments can drive an unsuspecting overclocking enthusiast up the wall with their seemingly contradicting results.

well.. maybe not the steadiest voltages ever..



then again boards do differ but only a bit

[zerotol]

can those bug finding please be confirmed ? because i am using all my options on auto almost and if those reading are true ??? wtf ?
