Go set the voltage to 1.6v manually in the bios... if it doesn't boot back down to 1.5v... if 1.5v isn't stable grab memtest86+ ISO and leave it running for at least a couple of hours or 10 passes (whichever is less)
If memtest doesn't show any errors, you should grab realtemp or something similar and see if it's not overheating
Another way to eliminate overheating would be to take the case off, point a big desk fan or similar in there, and run the PC... if it doesn't crash you know it was overheating...
For reference Intel say that CPU is good for up to 1.40V
Hmmm...BIOS says current CPU voltage is 1.15 volts. I set it to -0.1 of this amount so it should halt the volts a bit. Any adjustment of the RAM voltage othe than auto causes a non POST....BIOS keeps trying to boot, power off, power on, fail...repeat cycle
Just realised im using a 3 x 2gb kit that was meant for an i7 rig. Im using 4gb of this for my system.
Crucial part number ct3kit25664ba1339
I still think its a RAM issue. Wouldnt install win 7 until i unplugged one of the ram sticks (and the USB hubs). And seems more troublesome with 4gb instead of 2gb.
Hoping I wont have to buy a matched set of ddr3 4gb...when I have perfectly good ddr3 sat here.
On zotac website they only tested samsung and hynix with this board
Hmmm.....new thing to test. These guys reviewed my board and apparently there is a bug with the H55 Zotac BIOS (would have helped if I knew this).
They are using some nice gaming RAM, obviously not QVL....but had to manually set CAS latency to 10 to fix the bug
"Unfortunately, due to a bug in the H55-ITX BIOS we had to run the CAS latency at 10. Memory frequency on these boards was set at 1333MHz due to fact that the i3 530 does not natively support 1600MHz RAM. Interestingly, the BIOS on the H55-ITX has an option for 1600MHz but choosing it prevents the system from POSTing. However, when the i3 530 was overclocked the memory frequency was bumped up to 1500MHz while using the same timings."
Here is the link. Ill see how this gets on, maybe my pockets wont be emptied just yet
Weird it plays games ok but streaming video crashes. More RAM intensive?
New G Skill RAM installed. Everything set to auto. Mobo likes the good stuff, all runs great now. Sold the crucial on good old gumtree.
I have the same problem with brand new H55 HD motherboard. Any game cause freeze after a while (10-20 minutes) - the screen looks like a screenshot, mouse does not move, ctrl-alt-del does not work. Running win7 64 bit. The same with winXP. Could you explain how did you solve the problem?
