Windows 7: PC in sleep/hibernate -- won't boot now.

06 Mar 2010   #11

Windows 7 Ultimate x64

Hi, It is overclocked now. I have also been overclocking for awhile on various set ups.
However I wasn't aware the on board memory controller on the CPU's only supported 1333 ?

I just read the DDR3 2600+ support for the motherboard & thought that it should be fine. (& also fine to go a little further over 1600).

My individual CPU wouldn't boot successfully into Windows @ 4.2 Ghz (1.48 even core voltage).

I got it going fine BCLK 200 CPU x20 @ 4ghz 1.45 v (DDR3 600) real temp & prime 95 combo but one core got near the heat threshold & I dropped it back to 3.9 Ghz. & managed to get it stable around 1.32 V can't be too sure on my new Core voltage with out going into BIOS but thats what CPUZ shows from here.

I ran Prime 95 for about 8 hours @ 4.0 Ghz, but thats because I need to use the PC a lot & can't afford to leave it going much longer.

I tried other ratios but they didn't want to know.

win 7 x64
quick question

does your bios hav a big gap in ddr voltages?

i mean, i there are no ram voltages to choose between 1.489v and 1.559v, what gives?
The problem is that i have 1.5v ripjaws 1333 cl7. any idea how high i can go for voltage on these ripjaws when overclocking?
i had them stable @ 1733 cl9 @ 1.615v and 1.219 vtt. i have a feeling i could go higher or tighter timings with higher vdimm and vtt but i don't want to go over intels 1.21v vtt spec. (i know 1.219 is, but not by much)

i'm currently running my i7-860@ 3813 Mhz 22x173 ddr3-1386 cl7 with 1.28v vcore (idle) and 1.232v vcore (load) with 1.204v vtt and 1.489v vdimm 1.079v pch and 1.853v pll

but its also stable 22x173 ddr3-1733 cl9 1.219 vtt and 1.615 vdimm 1.079 pch 1.853 pll, but not sure if my higher memory oc will fry my ram. ANY THOUGHTS? any advice would be cool

Please Help

I have the same issue with my Acer desktop... It has been acting funny lately when trying to wake it up after its gone to sleep and this morning there was nothing.... I click the mouse or touch a keyboard key and lights on the keyboard flash but nothing else. I press the power button to do a hard reset and even unplug the power cable and let sit for a minute and still nothing but flashes on front and back of pc (Lan indicators, hdd led on case). I can't even get it to Post so I can get into cmos or do a safe boot. Can you assist?
