DFI LP UT X58-T3EH8 - First bench, bios screens etc

[eva2000]

What do u mean exactly ??


I OCed a little bit : (as you can know from another site) And problem with entering Bios still happens .



One more question, during Prime/Linx, Core speed differ between CoreTemp/Real Temp where multiplier was changing between 20x 21x , and CPU-z where it was most the time at the same level (4120MHz) U can notice this on above screen , compare Realtemp (4070MHZ ) and Cpu-z (4141MHz) . Is it normal ?? Which is more believable ?

Realtemp isn't accurate AFAIK maybe updating to 3.20RC4 might help but use coretemp 0.99.5 build 20 instead. But for multi use cpuz 1.50 to read it.

Ensure EIST is enabled when turbo mode is enabled.

You could also be triggering off the TDC/TDP protection modes which disable Turbo mode under high loads (triggered at >70A and >80W respectively). Read tip #3 & tip #25here including how to disable TDC/TDP protection and for Vista power manager to set to high performance (link bookmark it lots of useful tips )



Pushing some suicide everest runs with memory clocked to the max to see what kind of everest numbers I get



Best I can do for now

Anybody using W3520 on DFI UT X58-T3EH8 to confirm its working fine all the way with 2/27-BIOS, or another?

W3520 or i7 920 D0, which one would you guys pick right now?

[jcool]

I am using my 975 D0 with that bios and it is being recognized and working just fine, I don't see why a W3520 wouldn't work.

Realtemp isn't accurate AFAIK maybe updating to 3.20RC4 might help but use coretemp 0.99.5 build 20 instead. But for multi use cpuz 1.50 to read it.

I have found that Cpu-Z 1.5 will not read the multi change on my DFI 920 setup correctly.
I have found that Core Temp (a little erratic tho), Cpu-tweaker, and Everest will tho.

Can anyone submit his settings for anything above 4GHz? I ve tried 3 different CPUs so far, and cant get em above 3.8GHz on water.

If you can, use this template.

Thanks.

Dayum.. that template is bad. WAY too much VTT/Vdimm/ICH/IOH voltage.
And it's set to use a 17x mult

You have to find out which multiplier your CPUs like respectively. Some run great using 21x, some run better using the 20x, and some hate 21x and 20x but like 19x.
Also you probably need more Vcore with an average C0 920 to hit 4Ghz - just remember to test 20x and 21x as one will almost certainly be better than the other (=need less Vcore to be stable at a given frequency)

Try something like this:

[faster3200]

For some reason I can't get anything beyond 170 BCLK to be stable unless I push massive volts. I have tried two different CPUs and two different sets of ram. Think I just have a bad board?

[SwIeRsZcZ]

Is CPU VTT (QPI) at 1.36 - 1.38v safe for 24/7 use ? I have heard that it shouldn't be more than 1.35v

What rams exactly? May be a bad board but I doubt it.

[faster3200]

What rams exactly? May be a bad board but I doubt it.

My first set was a Aeneon DDR3 1600mhz kit. I got it pretty cheap, but I knew they weren't very good. The ram I am currently using is OCZ 1600mhz Platinum kit.

What is the max stable speed you can get with stock settings?

[faster3200]

What is the max stable speed you can get with stock settings?

170 BCLK, no matter the settings I get there, then I am stuck. I can get to 185 with vcore at around 1.58v and uncore at 1.56v, but anything lower than that yields no improvement.

Just for fun I might see how low a voltage I can go at those settings .

[Shadowjump]

Thanks, jcool. Gonna check it out right now.


And how do you enable Turbo mode??? I cant play with the Turbo mode multis at all and the BIOS shows 24, 23, 23, 23

Above the multis there is an option called "Turbo Mode Function". Also make sure you enable "Set VR Current Limit Max".

I have all that stuff enabled and still, no Turbo mode. And why 24 and 23,23,23 multis? Arent these reserved for the i940?

jsut enable EIST to access turbo mode
of course you shuld enable turbo mode option also

[unclewebb]

Realtemp isn't accurate AFAIK maybe updating to 3.20RC4 might help but use coretemp 0.99.5 build 20 instead.

At full load if RealTemp reports that your multiplier is dropping from 21.0 to 20.5, that's a pretty good sign that Turbo mode is becoming disengaged because of too much heat or power consumption. This can happen hundreds of times a second so RealTemp reports the average multiplier and rounds that off to the nearest 0.5 like CPU-Z does.

I wrote a separate tool that reports the multiplier based on the method Intel recommends:

http://www.fileden.com/files/2008/3/3/1794507/Turbo.zip

It reports the actual multiplier without rounding to 4 digits after the decimal point so it should be able to detect Turbo mode turning off sooner than CPU-Z or RealTemp does.

My Q6600 while running Prime is very steady at 9.0000. Core i7 at full load should be steady too using this method.



If it shows your multi dancing between 12.0 and 21.0 at idle then you need to set your power options correctly in the control panel to either fully enable or fully disable Speedstep. Some users don't have this set up correctly which CPU-Z ignores. In Vista you need to set your minimum processor state.



Set it to 50% or less to enable Speedstep or set it to 100% if you don't want it enabled.
Some bios versions will ignore your request to turn off Speedstep. If you need to have EIST enabled to enable the Turbo feature then setting this to 100% may not result in you actually getting your maximum multiplier at idle because the two settings are fighting against each other. Your multiplier really is going up and down like a yo-yo regardless of what CPU-Z, etc. are telling you.

In XP to fully enable Speedstep you might need to set your Desktop processor to Portable/Laptop in the Power Options -> Power Schemes.



Here is the Intel Turbo white paper that rge sent my way and outlines the method I'm using to report the multiplier for Core i7.
http://download.intel.com/design/pro...ots/320354.pdf

I'm not sure if CPU-Z is using this method.

Edit: One thing CPU-Z does do on Core i7 is it will use a multiplier less than the full multi to calculate the Core Speed but will still display the full multi. This might be a sign of Turbo mode just starting to become disengaged.



In this example, Bus Speed times Multiplier does not equal Core Speed.
Nice overclock raptord, what ever the speed really is.

That's a bios bug. Just follow the template I gave you, I enabled EIST there as well (no turbo without EIST).
The highest you can get on all cores is a fixed 21x mult by enabling EIST, Turbo mode, and setting the "set VR current limit max" option to enable (again, see template). With that option it won't back down from 21x even if you exceed the specified TDP of the CPU.

[Ancient_1]

Thanx unclewebb I never thought that is what was needed. I knew that there were settings in Vista but since there were no similar in XP I never thought I would have to list it as a Portable/Laptop to get it all to work correctly.

I didn't have it set to Portable/Laptop and once I did most programs now do read the correct multi. Some like widows and CrystalCPUID still read the frequency as a non turbo 20x cut most everything else is correct now.

thanks for the info

On DFI we can disable TDC/TDP protection completely via enabling Set VR limit Max as per tip #3 at http://i4memory.com/102537-post3.html

Where are these options ?

TDC Enable: Disabled
x TDC Limit: 0
TDP Enable: Disabled
x TDP Limit: 0

only really show up for 965 cpus to fine tune TDC/TDP protection but i rather just disable it altogether to prevent turbo mode from disabling when TDC/TDP limits are triggered as per tip #3 outlined here http://i4memory.com/102537-post3.html


so close to sub 9min 32M pi at <3900Mhz!



sub 4000Mhz 32M
