go on lupi you are my king. gimme a break.

Hope that will make things easier
What I myself have noticed regarding DRAM Voltage, is that it pretty much need to be at 2.2V, it failed to boot at 2.1V, but on 2.2V it boots all the time.

I have now changed to 8 x 375 as you can see and I get no immediate errors while Prime'ing (small fft's) so the next step should be to lower CPU Voltage right?

 

[iluvgillgill]

try turn FSB ter and NB volt back to auto since you are under 400fsb now.

 

[ps2asker]

FBS ter and NB Voltage is back to Auto, CPU Voltage at 1.45V and prime has been running stable a few minutes now at that voltage.
Temp in coretemp went up tp 73C, then I could hear the fan kick in and it went down to 70C(realtemp is 5C lower always).

 

[ps2asker]

Hmm temp seems to be going back and forth 70-74C and back.

 

[ps2asker]

Hmm just check in real temp, and when temp is at 70 it says 2250Mhz, when tmep goes up to 74 it's 3000Mhz?(temps from coretemp)

 

[ps2asker]

tested 1.40V, got errors. Testing 1.425V right now, though temps are well high I think. 72-73 in coretemp about 67 in realtemp.
Also seems as if it's got some safety function cause when it goes up to 73 it slows down to 2250Mhz to cool down. Not looking good for me I guess.
Question is now though, I'm happy with 3Ghz that I have now, is this setup okay? The only cpu-stressing task I do on my pc is watchin 1080p video content and that takes 15-20% load on all cores only, so temps should go that high then right?

 

[Lupiron]

Disable all CPU options, like c1e, Vanderpool, etc! Including the one called CPU TM function, thats thermal management functionality. It will stop if from doing that. 73, is high, but not hot. If you see 80s, you may thing about turning it off.

Its fine for the 8 hours of testing she needs if they are 75, but not 80 or over. (Though even 80 wont hurt it straight out.)

Gill, VTT is a touchy thing. It starts at 1.2000, so if just moving it to 1.4 doesnt help, 1.5 wont, UNLESS you are either at a very high clock, or a very low one!

Sometimes NVidia chipsets wont like it unless you change it straight out to 1.3000. But intel boards seem well off when left alone, unless going for 3.8 or more on a q6600, and 3.9+ on a q6700.

It can be used to eek out a few Extra Mhz when at an extremely high clock speed. But unless you have a high for its class overclock, 1.5000 just means the chip gets 1.5000 volts anyways, though his VCore was under 1.4000. Heat, anyone?

[Lupiron]

Did you even disable static read and write control, Transaction booster is I see... did it go better after T booster was disabled?

--Lupi

 

[Paris Lee]

i have ever use an big fan which is used by people in summer to cool the cpu haha
you may get its tepmerature down by 3~4f

 

[ps2asker]

Hey Lupi, no I have not disabled static read control or dynamic write control, guess I should?

 

[ps2asker]

Turned off CPU TM now, static read as well as dynamic write. Turned off TB yesterday, when doing that I need to set "relax level" 0-3, it's at 0 now, didnt help anything afaik.
C1E and vanderpool already off, running Prime again with 1.425v.

 

[ps2asker]

Seems to have been getting a little better now, max temp is 70-71 in coretemp and 65-66 in realtemp after 20 minutes prime small fft's, all this at 3000 Mhz.

My current settings, anything worth changing?

 

[Lupiron]

Okay, turn on CPU Voltage Damper. That should be that boards' equivelent to some load line celebration. With any luck, it changes the way you get voltage to the CPU.

To test it, stay at your current settings, keep track of your current BIOS VCore setting, then hit windows, and look with CPUz, and then run prime 95 small ffts on all cores for 1 min, and note the even lower value.

Once you have those three, turn on Voltage Damper from the bios, leaving all else the same, now boot into windows, and look with CPUz, hopefully, its more than it was when you didnt have it on! Next, run prime small ffts again for 1 min, and see what the lowest it goes to.

List both tests here!

[ps2asker]

Sorry for the delay in posting.
I did this yesterday and the results:

Damper OFF
No load: 1.376
100% Load: 1.256

Damper ON
No load: 1.376
100% Load: 1.256

Seems as if damper makes no difference.

 

[iluvgillgill]

doesn't the manual tell you what the function is?

 

[Lupiron]

Wow!!! That blows. Time to look for a VDroop mod.

They are rather simple to do, takes a pencil most of the time!

I will look for it a bit later.

--Lupi

 

[shadowthor]

this definitely requires a Vmod, 0.1V wow. There was a vmod somewhere on this forum showing where to shade.

 

[ps2asker]

I see, is it hard to perform a vmod?

 

[Lupiron]

Naw, it's very simple.

[ps2asker]

Sorry, but I dont udnerstand what I should do, all I understand is that I have to do something to that resistor with a pencil, someone said scratch it?

 

[Lupiron]

LOL, yeah, thats about all.

By running the lead tipped #2 pencil over that single transistor, it's going to leave a small trail of lead connecting the two ends, causing more power than the resistor was designed to allow to pass through, or over, the thing.

That effect is gonna allow more VCore power to get yo your chip in windows!

Just MAKE SURE you IDENTIFY that exact Transistor on your board.

If you really don't know what one it is, look for better Pics, and don't do it!

When you identify it positively, just sharpen that pencil to a nice tip, and scratch the thing from one end to the other in a few even strokes.

Blow any free lead from the entire board!

When done, just go into windows and load CPUz and see if it's better!!

May the Force be With You!

[ps2asker]

Just did the pencil mod, got some worrying results though I think:


No Load: 1.408
100% Load: 1.424

Have it set to 1.425 in bios.

please tell me if this is bad asap so I dont damage anything.

 

[ps2asker]

I redid it as I figured I had lowered it to much before(from 52 to 2 on the 200k Ohm setting on mm), this time to 19. Results:

No load: 1.408
100% Load: 1. 392

Should I lower it further or leave it there?
