No problem. I tried 1.74V on cheap Kingston KVR1333. It isn't even hot when touched.

You just have to ensure Vtt difference is not more than 0.5V. Usually motherboard BIOS will take care of this for you.

wow!!1.74v how dare u? whistling.gif i m testing 9-9-9-27 2000mhz~at 1.68v oredi 4000 uncore~add summore to vdim will help in this?

i've read some articles on Intel Socket 2011/X68 will b in Q3 2011
4 single channel ram..and might b PCIE x16 3.0
so i wonder is it worth it 4 upgrade? or our X58 still gud enuf?
if really gud then i'll follow..u jump i jump...

not much we know about this LGA 2011 socket... hmm.gif
need to wait for more info lol...
but sure it will be faster than sandy bridge...
i think... laugh.gif

Cheap value RAM only. Moreover it comes with warranty. I wish I can burn it off but it just wouldn't. laugh.gif

How much VTT you using for 4000 uncore?

ya, same like my siggy, still testing now~~but using 1.525V now for VTT~not yet stable~windows reboot after 1 round of linX
*

For uncore 4000Mhz u just need VTT around 1.4-1.5v. Watch out for PWM temp windows will reboot once this evil temp hit ~ 100C

How much can the PWM withstand? DFI monitoring software already show red @ 60C. laugh.gif

P6T doesnt hv PWM aka VRM sensor this cant check its temp sweat.gif
Even R3E also u hv to plug sensor cable on this area but is not quite accurate.

DFI will throttle once PWM temp exceeds 85C. Ur hybrid digital PWM can withstand temp up to 105C.
But according to Jimmy the DFI engineer, overheat PWM won't cause shutdown hmm.gif
Somehow this guy keeps mum when I questioned uptil now DFI still didn't managed to overcome the high PWM issues in their boards.
Most DFIs died due to evil code 88 error, this stupid guy replaces the burned CPU PWM IC,w/o knowing that actually it's caused by electric-attribute changed of some components on CPU VCore circuit and damage PWM IC again. Pity those DFI buyers RMA few times again and again. There are many DFI boards still waiting RMA turn at local distro atm.. Good luck.
But now I'm glad that this MF mobo maker has stopped producing LP boards.

The 21th multiplier is being throttled down @ 4GHz settings. Temperatures are fine except for PWM that is over 70C. Is it over-current protection?

Once ur PWM temp reaches certain limit (85C in my case), Turbo mode will be closed, min multi executed and throttled.
In bios settings, to remove throttling, do the following protection functions
Set VR Current Limit Max: Enabled
TDC Function: Enabled

I did Set VR Current Limit Max: Enabled and it no longer throttle down. Thanks

I manage to hit 4GHz, but the system couldn't sustain. While Linx never gave error and neither Windows BSOD or acted weirdly, DFI monitoring software alarms me for a great dip in voltage for
Vdimm: ~1V
+5V: 0.somethingV
Vcore: 0.9V

Then few seconds later whole system will shutdown (not restart/BSOD) and stay off until I manually start the system. I also noticed that the PWM temperature are 75-76C when this happened.

PWM overheating? PSU can't cope?

PWM OCP set to 140A. PSU is Silverstone ST-56F

The blinking red voltages show that ur system is being throttled due to PWM overheating.
U will see voltages shoot up and down and cause shutdown etc... Nothing wrong with the OCP just let it be.
The solution is try to reduce the PWM temp by active cooling ie small fan + table fan blowing directly towards PWM & NB
TIM needs a replacement too, argh this DFI puts red glue on the NB screws doh.gif

Okay, I'll get a fan to blow and try again. If I remove the PWM heatsink, warranty would be void. Moreover I heard it's difficult to align the heatsink for perfect contact again.

Sidenote: Why -12V rail has a ridiculous reading?

That's fine with the negative railing. Not the issue.
