Just built my new rig. DS4 / E6400 / OCZ 6400 (OCZ2P800R22GK) / Palit 8800GTS / Corsair 620W.

Now despite the fact the memory dropped in price by £40 in 2 weeks :( the PC worked great for 3 days.

But now it has started doing some wierd power on stuff.

Sometimes the PC boots fine.

Other times it just powers up for 2 seconds, starts fans, cds, etc then turns off. It then turns on again after 2 seconds and so on and so on and so on.

But if I remove the power from the back of the PC for 5 seconds or so it then works :confused:

I read these posts and wondered if anyone knew whether these applied ?

Any ideas / help please ? Would it help to reset the BIOS ? Could it be a setting in there ?b

sounds like a ram problem, the ds4 sets the voltages too low for some ram and you have to manually adjust them to get it working properly. i had the problem at first, try a bios update and check the ram voltage.

if you are overclocking keep an eye on your ram and make sure you don't push it too far cos the cycle starts again if you do

(speaks from experience and numerous mobo bios resets)

OK thanks, but I have the VDIMM at +0.3 so at specified voltage of 2.1.
 
only other suggestion i can make is if you have more than one stick try them individually for a time see if it hapens again, could be a faulty ram stick,

when i got my ds4 i had 4x 1gb sticks of corsair cas5, 2 worked in my mobo and 2 didn't but worked in my mates asus board so they can be tempremental. if you do end up changing the ram i'd recomend This
I have 4 sticks of it in mine and it runs without a problem
 
yeah thanks, it just difficult to prove its the memory as its an intermittent problem.

Thought it might be a PSU problem with it being overloaded at boot (obviously it shouldnt be given the PSUs a 620W) as dont even get to the BIOS screen.

Will be annoyed if it turns out to be the memory as I was going to buy the Geil but saw a few bad reports about some faulty stuff around the time I bought my kit.
 
I was going to link you to the DS3/4/6 guide when I read the start of your post LOL. I'd have a word with OCuk, if you can exchange the mobo now, you could save yourself a lot of trouble down the line.

Not positive its the mobo though, could be the memory or the PSU. Will need to test it with some other memory. Problem is the issue is intermittent. :confused:
 
If your only on revision 1 then it almost certainly the reboot issue as described in the gigabyte sticky in the motherboard section. I would RMA it pronto.
