Did anyone experience an oddity in that their 1 year old stable overclock all of a sudden is no longer stable?
I noticed this when I would get black screens (monitor goes into standby, game music keeps playing and shortly after a hard lock)
happened first with SC2 then the FFXIV benchmark and now prime is no longer stable for more then 2 hours.
I'm wondering what could be giving up after time?

May be the hot summer days are causing the problems? That`s why when I`m testing my 24/7 overclock in the winter at 20-22 ambient I`m testing with prime or linx. I know that if I`m close to 80-85 degrees it wont be prime/linx stable again in summer days when the ambient temp is 30+ but I dont care cause I cant really load the CPU as much as these 2, and even now max CPU temps I can see for normal work not benches are 60-70 degrees. Yeah it happens to me 12 hours prime95 to be unstable after a period of time but I know the reason(overheating) so I just dont run prime in the summer . Also never had problems in games or whatever as soon as the CPU is not overheating. Anyway 2 hours prime should be stable enough for gaming. I think its not ur CPU may be the PWMs or NB are overheating or may be the memory. I have played games so many times with CPU which cant hold more than 10 sec prime and never had problems , but I guess its accoriding to the game or the CPU.
Same Bios?
I am still thinking about trying one of these boards. Was looking at the e760 classified, but waited and now it is more $$$ than the e762. Can get the e762 for 389.00 at newegg, may just go for that. Only concern I have is still the board temps, have no plans to buy the block for the board and change my loop.

Yeah same bios, same everything. Not really convinced its the heat as my system is watercooled and has far more heat dissipation capable then anything can put it under.
I've heard of the effect called 'electron strain' where the silicon starts leaking current due to being under extra voltage then 'normal' for some time. In this case usually its required to increase the vcore a bit to maintain the same overclock but I've tried that and still nothing. I'm wondering if RAM can start giving out after a while though I haven't ever fed it more then 1.65V

You change gfx cards, or clocks on the cards? I got the black screen on my 5870 last night playing bc2 on a tested stable oc with my cpu, but gpu at 950 core needed more juice.
Did change the gfx cards but its possible that the new FFXIV benchmark (which is the quickest way for me to test stability) didn't like my previous clocks which were stable under Vantage and any game I've put it under. I've had to backdown from 1025core to 950core. Trying 975 produced the same error. This is maxed at 1.3VGpu.
Problem may have been two fold though. Gonna have to find Linpack again and see if the CPU/RAM connection is indeed fine.

Doesnt look like the e762 will even come close to fitting in my antec 1200 case lol. newegg has it for 399.00 with a 100.00 mir, not bad 299.00 for that board though.
Hey guys just setup my e760 and it seems to be working great.. I am having one issue.
The machine is in standby mode (blue light) and is reporting error "FF" does anyone know wtf this means?

LOL My CPU can also run uncore 4000 with 1.4vtt, but there is no chance to stabilize 4200, it can boot and bench with 1.4vtt again, but even 1.5v is not helping for stable work.
With higher uncore do you see better perfomance in gaming/folding, or is it just for benching? Is vtt the only voltage that needs to be adjusted for higher uncore?
