Before I start I have 4 x 1 gig OCZ Reaper HCP DDR2 PC2-8500 and an Asus P5B Deluxe
On Friday afternoon I tried some tweaks to my ram timimngs and upon restart all i got was one longiish beep and then three shorter beeps. But the PC would not reboot or even POST, with no monitor activity whatsoever (stuck in standby mode).
Tried to get to BIOS to go back as before the timing changess, or even back to default as that was what i thought the problem was, although the timings and voltages were well within the RAMs limits. Nothing - the beeps just kept going in cyles of three and then rebooting, beeps rebooting etc.
So, i whip the side of the case off, out with the CMOS battery, jumper settings reset, battery back in, restart - Exactly the same thing.
At this point im thinking, arse one of the sticks has gone, so all are taken out and reinstalled individually, one by one. The machine will start, as normal, with three of the four sticks in singularly, so i have identified the culprit. Then try 2 and 3 of the remaining sticks and all is well with 2 or three sticks in, but same no POSTing issue as soon as the fourth is installed - so I initiate an RMA with the supplier (not OCUK).
So on Saturday I try memtesting the remaining sticks, as one will have to go back as part of the RMA (they come as 2x1 gig pairs).
Each stick has a short memtest of 3 passes - about 40 minutes a stick. No obvious problems, so the intention is to Memtest a pair overnight on a longer test.
Then, out of curiosity, I decide to see if I can get memtest to work on the "dead" stick and bugger me - it not only works, but runs for well over an hour, four cycles with no iussues what so ever :S
So, in with all four sticks and what do you know the PC boots as normal and all is fine - 3 1/2 hours on Prime95 blend test without a glitch.
I then left memtest running overnight for 9 hours with all four sticks in and no probs !
Is is safe to say that the stick is back from dead and all is fine ??
And does anyone have any ideas of what / how this happened ?
Cheers
