cannot run rams on 2000mhz

katalizor · Mar 21, 2010

Hello Everyone

Just as you can see below, my RAMs is working on 1600mhz for now and When I have pushed them 2000MHz(of course by changing BCLK), PC just hangs on a black screen at the BIOS boot so I understand they require a bit more voltage. Ant these are also my stable settings:

Ai Overclock Tuner - Manual
CPU Ratio Setting - 19
Intel (R) SpeedStep (TM) Tech - Disabled
Intel (R) Turbo Mode Tech - Disabled
BCLK Frequency - 211
PCIE Fequency - 100
DRAM Frequency - DDR3 - 1688MHz

DRAM CAS# Latency - 9 DRAM Clock
DRAM RAS# to CAS# Delay - 9 DRAM Clock

DRAM RAS# ACT Time - 24 DRAM Clock

(2nd Formation: 2T)

QPI/DRAM Core Voltage - 1.3250v
IOH Voltage - 1.10v

Additionally I tried to give 200BCLK 1.5v qpi/dram voltage, even 1.8v dram bus voltage and 1.3v IOH voltage but I could not run 2000MHz. And XMP profile does not work.

My mainboard is a cheaper version(Asus P6TSE). I have been told It can be problem and I have also read a bit article about 2000MHz rams and It was telling 2000MHz rams are not really 2000MHz and so on so on.

Main and final question: Is there anything that I can try BIOS setting or any more thing?

Please Just help me to run them on 2000MHz.

Thanks a heap in advance.

Respects

I would try a BCLK of 200, Multi 20 to get the rated speed of 2000MHz, increase the QPI voltage to 1.6. IOH voltage and CPU PLL will probably need to be increased also. If I've selected the correct memory on the Team website then it's specification says it needs 1.9V! which isn't exactly a 'friendly' voltage for socket 1366.

Following the rule that the QPI voltage should be within 0.5V of the DRAM voltage then the QPI would need to be at least 1.4V.

wow, 1.6v qpi and 1.9v dram bus will just kill my chip, I guess. in long use, such a big voltage can damage?

I cannot take that risk.
The only way is buying another good ram kit which requires less voltage and less mhz but better timing, right?
