I920 + Asus P6T SE - memory voltage stuck? - General-Discussions

Greeting all,

I have my new system up and I was following previous discussions on how to overclock that are pretty straight forward: http://www.tomshardware.com/forum/263658-31-done; http://www.tomshardware.com/forum/ [...] cking-help

However, I cannot tell if my Dram voltage actually increased to the value I entered in the Bios. The Dram frequency in CPU-Z shows 719.8, which if I multiply x3 = 2159.4 is way more than I was trying to achieve. But the voltage still shows 1.5v. I'm still a bit of a noob here so please bear with me.

System
Intel i920
Asus P6T SE Bios v.0403
XIGMATEK Dark Knight-S1283V
Mushkin 998681 (3x2GB) XP3-12800 rated at 8-8-8-24 1.65v
ASUS EAH4870 DK TOP/HTDI/512MD5 Radeon HD 4870 512MB
Western Digital Caviar Black 640GB SATA
Antec P183 Case w/Antec CP-850 850W Continuous Power CPX
Windows 7 64 bit RC

Overclock Settings (only includes changes)
Speedstep - Disabled
BCLK - 180
Dram Freq. - 1443
UCLK - 2887

CPU Voltage - 1.3000
CPU PLL Voltage - 1.88
QPI/Dram - 1.3000
QPI Data Link Rate - 6.4mt/s

I would display the CPU-Z images but cannot figure out how to cut & paste with this new OS.
CPU
Core speed = 3598
Bus Speed = 179.9
QPI Link = 3239

Memory
Dram Frequency = 719.8
FSB Dram = 2:8
8-8-8-24

SPD
Voltage = 1.5 http://img.tomshardware.com/forum/ [...] /icon9.gif

Real Temp
Min. = 40
Max. = 47

Can someone please tell me if the CPU-Z SPD display of 1.5v is correct and if so why my manual setting of 1.65v in the BIOS did not take?

Also, I am open to other overclocking setting suggestions.

Thanks

SPD stands for Serial Presence Detect, which is the automatic configuration voltage of your DDR3 memory and should ALWAYS say 1.50V. CPU-Z does not read the set voltage, and the SPD page will always show the same stuff no matter what you set your memory to.

720 MHz is DDR3-1440. I don't know where you came up with 3x, when it's DOUBLE data rate. And if you're reading that off the SPD table, forget it because the SPD table represents fixed values, not set values.

Thanks Crashman,

I thought I read where triple channel meant you multiply by 3; like I said I'm a noob here. I ran Prime95 and my temps topped out at 77C. Which is not as good as I hoped. So I'm going to step down the BCLK, and try to get my ram up to 1600 where its supposed to be at.

For Dual-Channel you double bus width, not frequency. For triple-channel you triple bus-width, not frequency. So you go from 64-bits to 128-bits to 192-bits. But nobody mentions that, they just say single, dual, or triple-channel.
