Hi all, got a problem thats been taxing me for a few days. Wondering if any of the boffins on here might know. Had my amd 3200 comp overclocked and prime stable for 24 hours + running at 2.6 ghz. more than happy to say the least. Screaming performance. The other day my comp was on and we had a power cut in the street everything obviously shut down rather rapidly. Got everthing plugged into a spike /surge protector so hoped eveything would be ok once the power came back on. when the power came on i got a beep (usually memory problem) and no post. Had to reset bios. all ok post and load to windows. But back to stock speeds. With the Lanparty mb you can have 4 differeny bios setting profiles saved and swap between then as needed. So i loaded up my overclocked settings that had worked perfectly before. Got the error beep again. no post. Would work on stock though. So ive had to clear the profile and re-overclock (change all setting and timings manaully) back to 2.6 ghz. post boots all seems to be ok. But heres the thing. it now passes memtest 1.65 8 hours plus no error. Passes stress prime 8 hours plus on cpu test. Fails after 18 mins or so on blend or mem test. Does anyone know why this might be happening its as if my memory fails in windows but not in memtest. Could it have been damaged with the power cut in anyway? just cant work out why. Tried relaxing timings to 2.5,4,4,10 @260 ok in memtest but still fails in prime testing. Before it was happy at 2.5,3,3,6 @ 260 for days. Its seems like suddenly my memory has become reluctant to overclock like it did before? Any help from you experts is appreciated ive also got this posted on DFI-STREET.com but trying to get as many suggestions as posssible thanks again AMD 64 Venice E6 LBBWE 3200 Running at 2.6ghz 1024 Crucial Balitixs tracers 1:1 1T 2.5,3,3,8 @ 260 DFI LANPARTY UT ULTRA D 6800gt 425,1200 CD+DVD 2x80 gig sata raid 0 1x80 gig pata

I've heard that prime can be a bit offish with 64 systems?Not sure really? I use OCCT now. Seeing as the memory controller is on the CPU maybe the CPU is damaged in some way? Tt Lanfire MSI K8N Diamond AMD64 3000+'Venice' 1gb pc4400 OCZ Powerstream 520w 6600GT WDCaviar 160gb sata x2 ;~}

Yeah you may want to take it down to a pc shop and have someone run hardware test on it. The brownout may have damaged something and my guess is that it could be your ram. First try installing new ram. if you get no more problems then you know what caused it. If it still doesn't fix the problem then you can always take that ram back and get your money back on it. I don't think it's the processor or else you be having problems with it even on defualt speed. it's either your ram or motherboard, but my guess is it could be your ram.

By your description I guess you use one of these power extension cable with a number of plugs, a switch and that surge protector in it. The problem is those only protect against low level spikes. I askes an electrician a while ago about that and he said if you really want protection you need a low, medium and high level protection build inside your houses power distribution system. The problem is that will be very costly so usually it makes not that much sense. Because of that I guess it's not impossible that a few peak got through into your system and did some sort of damage. I agree it might be the ram so if you have two modules try them out seperately in single channel mode. Maybe one will work and the other cause errors.
