Quick Hardware help/question

[Dove32]

Afternoon all,

I have recently purchased a P7P55D-E and the Patriot Viper 2 Sector 5 4GB (2x2GB) PC3-18000C9 2250MHz Dual Channel Memory Kit along with an Intel i5 760.

I am currently in the process of setting the memory at the correct clock speed however i am having some major problems.

There is a X.M.P profile on the board with all the correct settings for the memory and voltages etc. when i choose the profile the machine saves the BIOS settings and then fails to POST. I reset the machine and it says overclocking failed etc and sends me back into the BIOS.

The BIOS is on the latest version.

I have given up on this profile and tried changing all the settings manually but still has exactly the same problem, whenever i get the memory BLCK above 210 it fails to post.

Im not sure what else i can do...

Current settings are -

CPU Ratio - 14
BLCK Frequency - 208
PCI Frequency - 100
DRAM Frequency - 2080

CPU Voltage - 1.2875
IMC Voltage - 1.2625
DRAM Voltage - 1.6875
CPU PLL Voltage - 1.800

Memory timings are 9-9-9-27

With these settings the machine is stable and runs fine, but whenever i increase it anymore or select the XMP Profile which automatically adjust the settings the machine no longer posts.

Any help would be greatly appriciated.

Well it looks like your motherboard is limited by a BCLK of ~210, in which case you can't do anything if you're already on the maximum RAM multiplier.

Thanks for the reply, however why on earth would they have a profile that adjusted the clock to 225 if it doesnt support it? Also on the product information on the OCUK site it does say - Memory: 4x DDR3 DIMM 2200(OC) / 1600 / 1333 / 1066 MHz (Max. 16GB) / Dual Channel / Intel Extreme Memory Profile (XMP)

Also someone posted feedback for the memory and said he has exactly the same setup and it worked for him?

XMP doesnt always work. I get a much better overclock with it turned off. Memory speed has such a small effect on system performance it's not worth worrying about.
