Here is the rig

i7 @ 3.3
FREEZER 7 PRO REV 2
4GB CORSAIR DDR3

I have it at 20x160 (i think) if i try and go over it will get stuck at the bios screen or not post at all

CPU Voltage is at 1.240
RAM is at 1600 MHZ

What should i do to get it a little higher say 3.5

Thanks

Probably bad. I mean, it may well be good RAM and happily do the speed at stock volts - but there isn't any guarantee.

I suggest going into the BIOS and kicking the memory multiplier (or it may just be shown as the RAM speed) down one notch so that the RAM is running within spec speed. Have the RAM voltage and timings been set correctly as well?

QPI link? Are you seeing that in the BIOS or CPU-Z?

If its just in CPU-Z then don't worry - it says 2.4GHz at stock and it should scale with increased CPU clockspeed. So it should be saying around 3.08GHz now.

Hehe, trusty Ti83 always at my side :)

QPI is basically a connection that links the i7 cpu to the chipset. I replaces FSB used in earlier Intel Chips. However, it really only works like this on the X58/Bloomfield platform, Lynfield P55 chips like your i7 use something similar called DMI. I think CPU-Z just decided to keep the "QPI" name in their app for lynnfield chips.

Your setup appears to be behaving in exactly the same way as mine (i5 750 on a P7P55D LE).

It is the RAM, you have 1600MHz RAM and your BCLK is at 160 so the divider puts you right on 1600MHz which is great.

If I go even 1 MHz over the a BCLK value that gives me 1600MHz selected on the DRAM speed then the PC won't post, it's a bit crazy...

Try upping the BCLK to 200 with 17 on the CPU multi and work up from there.

Something to watch out for...... If you set the DRAM speed to 1600MHz beforehand, then change the BCLK up to 200 you should notice that the RAM speed has changed, go into the setting and reduce the speed back to 1600 before saving and rebooting otherwise you will crash again.

The dividers I have used so far are:
x5 (160 x 5 = 800 (then doubled because DDR))
x4 (200 x 4 = 800)

I would not suggest upping the CPU voltage just yet, see how you go with what I have said...

got it 3.8 with the ram at 1650 mhz. voltage is 1.3

how do i force the ram to stay at 1600mhz. its passed intel burn and temps and everything else seem to be fine
