What's wrong with my overclocking ?

post #1 of 16
Thread Starter 
Hello,


i need some help mad.gif

I receive my new rig monday, and i started to overclock it.

So, here my spec rig:

5820k
X99 Strix
4*8gb Ripjaws V (3333mhz CL16)
SLI 980Ti
RM1000i PSU


I'm able to reach:
4.2ghz core with 1.21v (adaptive)
uncore 4.2ghz with 1.21v (offset)
blck = 100mhz
ram = 3200mhz 16-16-16-36-1T (1.35v bios=> 1.33v under windows)

PCH @1.175v
VCCIN @1.92v => @1.90v load
VCCSA @0.88v => 1,016v load

LLC level 5

OCCT is OK

All settings:

160607223538.jpg 160607223556.jpg 160607223704.jpg 160607223719.jpg

160607223733.jpg 160607223742.jpg 160607223801.jpg 160607223823.jpg

160607223846.jpg 160607223900.jpg 160607223909.jpg 160607223935.jpg

160607223945.jpg

After that, i wanted to play some games to enjoy my new rig with my new screen, but no....

Playing GTA V or DOOM simply shutting down my computer (doom after 3 minutes and GTA V after 10minutes... no BSOD, no errors, nothing, just a,shutting down.

I investigated about PSU problem, but RM1000i is just brand new, and support 82A on 12v rail and when GTA V or DOOM is lauched, i have 50A usage with 980ti SLI, i try to switch off OCP with Corsair link (mono rail) same problem... shutdown when rig is under load in game....

I do some cross test with one GPU, same thing here...

OCCT in large data set does not stress the RAM enought maybe ?
(I must test RAM with 12 instance of memtest to see if i can reproduce the issue...)

Do you see something wrong in my BIOS settings which should problematic with my issue ?


Some people already have this issue when overclocking their haswell E ?

PS: sorry for my english, it's not perfect redface.gif

Is there some over current protection setting in the ASUS BIOS that you can disable? If yes, try that as that can be buggy and not reliable to use.

Thank for answer.

I have found the problem after all night on it...

It's the uncore... i set multiplicator to 41 and everythings was fine now... My CPU don't want 4200mhz on the uncore, don't really understand, no matter what i was putting on voltage !

I adjust some voltage to lower value now, cause i was thinking it was other value cause my shutdown, but no, simply the 42 multiplicator to uncore...

Here is my final overclock:

Bclk = 100mhz
core = 4200mhz @1.21v
cache = 4100mhz @1.195v
VCCIN = 1.85v load => 1.88v idle
VCCSA = 1.008v
PCH = 1.105v

LLC = level 5

Ram @3200mhz 16-16-16-36-1T @1.35v


no more shutdown, and i can enjoy my RIG !


if someone have explanation why my rig shuting down when i have 4200mhz uncore even if i adjust VCCSA, VCCIN or vCache...

maybe someone have an idea about the shutdown when cache is upper than 4100mhz ?

I can't figure out why the rig simply shutdown underload when cache is set to 4100mhz+ frown.gif

If you have not done so already read through this thread. There is a link to a OC guide at the top.
http://www.overclock.net/t/1510328/asus-x99-motherboard-series-official-support-thread-north-american-users-only

I have not OC'ed an X99, but I would say that you need to increase your vcore and/or cache to get above 41 on your cache. You may also need to increase your VCCSA, but read the OC's guide that have links in the first post on that thread and then read through the tread.

increase vcore/vache even if i set 1.30v can't pass at 4,2ghz on vcache; Doom or GTA V , shutdown the computer after few minutes...

but OCCT/AIDA or Furemark pass without problems...

I really don't understand what's wrong...

Did you monitor you CPU and GPU temps with a program like Hwmonitor or hwinfo64?

qwrty, my guess is you're reaching 85-90C and your pc shuts off.

Yes.

Actually i have 4.3ghz vcore @1.24v and 4.1ghz vcache @1.19v => pass OCCT one hour.

No temp problems with the h100i v2, max core is 78 degrees during OCCT.

My other settings:

blck = 100mhz
ram = 3200mhz 16-16-16-36-1T (1.37v bios=> 1.35v under windows)

PCH @1.110v
VCCIN @1.85v => @1.86v load
VCCSA @0.88v => 1,016v load

LLC level 5

Can't pass 4.2ghz cache ingame even with cache @1.30v ( and even if i increase VCCSA)

no problem @4.1ghz....

But why in game ?

During OCCT/AIDA or furmark (all at same time) no shutdown...
And during my game session on DOOM or GTA, i have OSD with HWMonitor temp, and all seems good....

And no problem with 4.1ghz cache.

I will retry this evening with more cache voltage...
