The Rampage II Extreme Thread

[converge]

I've been having my first play with the board and just wondering if it's normal for it to increase core voltage under load? I have llc enabled and my core voltage set 1.25v, however when I run linx it increases to 1.27v - 1.28v

anyone? this is driving me nuts, over volting by 0.03 - 0.04v seems pretty significant to me.

normal for LLC enabled nothing to worry about. For 24/7 it's best to disable LLC though, leave LLC for bench/max oc sessions.

thanks for the reply eva. seems to be much less stable with llc disabled =\

LLC disabled will need high vcore set in bios so the droop vcore under load is sufficient for the clock speed you want. It's safer for the cpu though i.e. 1.456v idle and 1.416v load with LLC disabled. Idle higher vcore has jack all stress on cpu compared to 24/7 LLC enabled heh

Gday

I am chasing a bit of info on the board please
Just looking at my Rampage II Extreme and it has a jumper just to the right CLRTC Jumper.

I can't find anything in my manual that says anything about this 3 pin SW ( Has a jumper on pins1and2 ), Even all the MB layout Pics in the Manual don't show this 3 pin SW, I have on my board to the right of the 3 pin CLTRC switch.

Also on further inspection there is a 8 pin switch block that has one pin removed ( 7 pin with No Jumper caps). and this block is located between the CLTRC SW block and the BIOS chips below . No mention in the manual what this is for either . and in all the MB pics in the manual, this SW block is not shown too

Could you please tell me what is the purpose of these 2 SW blocks please.


If it is of any help to you. My Motherboard revision is Rev 2.01G

could be for that external oc'ing panel device Asus have for ROG ?

Ive got a problem to get higer BCLK than 207 on my i920 (RIIE & Bios rev 1639) .

Now I am 207x21 and its rock solid, almost half a year without single crash/bsod , working 24/7 .
Today I tried once again to put my clocks higer but unsuccesful... with BCLK208-210 system can hangs-freeze and I had to make hard reset... (temps are fine...)

This is my bios template settings:

CPU Ratio setting - 21
CPU Turbo Power Limit - Disabled
BCLK Frequency : 207
PCIE Frequency : 100
DRAM Frequency : 1659MHz / timings 8-8-8-21 trfc-88
UCLK Frequency : Auto
QPI Link Data Rate : Auto

CPU Voltage - 1.38750
CPU PLL voltage - 1.81592
QPI-Dram voltage - 1.28750

IOH voltage - 1.11341
IOH PCIE voltage - 1.51106
ICH voltage- 1.11341
ICH PCIE voltage - 1.51106

DRAM Bus voltage - 1.65681

CPU configuration
CPU Ratio Setting : 21
C1E Support - Disabled
Hardware prefetcher - Enabled
Adjacent Cache line prefetcher - Enabled
Intel Virtualization Tech - Disabled
CPU TM Function - Disabled
Execute Disabled bit - Disabled
Intel HT Technology - Enabled
Active Processor Cores - All

Intel C-STATE tech - Disabled

Load-line calibration - Auto
CPU differential amplitude - Auto
Extreme OV - Disabled

CPU spread spectrum - Disabled
PCIE spectrum - Disabled
CPU clock skew - Auto
IOH clock skew - Auto

Any ideas what I should try first ?? I tried rising QPI to 1.31v, vcore to 1.4 and nothing. Maybe PCIe ? IOH / ICH ? Temps are fine...
