Ahh didnt know it was only am3, they do an am3+ chvi now
post #282 of 4095
After tinkering for a day, I just can't get prime95 (custom with 6000mb ram used) pass for more than 1hr at 4.5ghz. Either core 5,7 or 8 gets error.
I playEd around with cpu@1.332-1.386 and cpu nb @1.2-1.275. It just fail at 40-59 mins, higher voltage fail faster, lol. Temp are perfectly fine tho.

Can anyone have Any suggestion ? Maybe nb voltage?

Eureka! Finally... How is folding at full load and 4.0 GHz at 39*C? I haven't responded back to this thread because I wanted to get it right unless I was all wrong which was real close. I did many reapplications of the Antec Formula 7 TIM and could not get the temps down that was reaching max recommended temps. I tried the grain of rice in the center and it would not spread out. I tried spreading it thin and thinner with a razor blade and I would get max temps that wouldn't go down. I tried my finger in plastic and this stuff would not come off the plastic as I was trying to apply it. This is really thick stuff and hard to spread.I must of had a great amount of this TIM. Not because I was using a lot but because I must have tried in so many different ways to get this stuff to spread evenly. Finally I was rdy to buy arctic 5 at the home town radio shack but thought I would give it one more try. I applied it in a "x" form on my cpu from the recommendation here Finally low temps were coming. I burned it in for another 12 hours. This morning I tried folding with it. The core temps came to be 39 to 40*C. The Socket temps @ 45*C thanks to this thread's advice to place a stock cpu fan to blow air on the bottom of the socket. I am feeling pretty good about trying to reach my 4.5 GHz goal thanks to this thread but waiting for my FAH work unit to finish. Wish me luck
.

What cpu voltage are you setting for 4.5ghz to fold?

Haven't yet. I am only 4.0 GHz since I started to burn in the TIM successfully. This night I will make my move for 4.5. Currently 1.35v for 4.0 GHz. I will let you know if 4.5 is successful.

K.. currently folding at 4.4 GHz at 53*C average core temps and 1.38V. I haven't attempted 4.5 GHz yet. I don't know how much voltage it would require as I think it will fold too hot. Still for 4.4 GHz I think 1.38v stable is pretty good. When I have both pc's in this room folding the room is so small that all the heat gets trapped in here hurting my overclocks. I really don't believe there is much more I could do to reseat the FX-8120. It is at my most coolest temps yet being before this guide I couldn't keep any freq higher then 4.1 GHz. I will have to weigh things out to decide whether a 4.5GHz attempt is worth it.

i have tried that. every time i set them manually it blue screens.

Try loosening the timings or dropping the speed a little

I usually test my overclocks for one week minimum on F@h to determine stability. Also, when I moved from 4.4 to 4.5 it took quite a chunk more of voltage to do so to get it stable. And heat, just a heads-up.

Thank. Good advice I think. I felt the same way. I can be satisfied with a 300 MHz increase @ 4.4 GHz over a 4.1 GHz it was probably a week ago.

Hi Maxboy,

It could be an issue with the Ram if more CPU voltage doesn't help with failing. What error is Prime95 giving? Also, is it version 27.7 or newer? Also, please fill out the Rig Builder info so I can see what hardware you are working with.

Which model of Low Profile Ram do you have? I ask because some versions use 1.35v for 9-9-9-24 @ 1600Mhz.
Make sure all the Ram have the same #'s and try them as individual pairs. (Only 2x4 at a time)

Looks like your FX8120 OC is about the same as my FX8150. It took 1.4v for 4.5Ghz and 1.435v for 4.6Ghz. I'd bet you could do 4.6Ghz. You have lots of headroom still as you're under 62 Celsius on the Core. 62 is the max 24/7 Temp, so don't be afraid to hover around that mark when Folding.

Looks like your CPU block is seated well now, so sometimes you can even lower temps more by playing with fan profiles. I can't remember what your profile was now, but you could even try a Push/Pull setup having the Radiator is the intake for the case.

I am currently found my highest point of overclock @ 4.8Ghz considering that 4 hours is good without warnings. If I add more bus speed or raise the multiplier, one core stops in prime test. If I add core voltage, it freezes. Max core voltage that it hits is about 1.521v. temps at prime is max 62C. HT is running @ 2200Mhz and NB @ 2400Mhz. Voltages are raised with .1volt both. It is Very good overclock IMO considering that I have Asus M4A89GTD PRO and FX-8150 with Crucial Ballistix sport running @1500Mhz with 9-9-9-24-2T. As a cooler I am using corsair hydro H100 with Noctua fans(not push pull only two fans). It broke down last week and its waiting for RMA. After I get it back, I'm about to post some pictures of the overclock and thinking about hitting to the peak with this chip. By the way I have noticed that bulldozer has little bit more overclocking potential than the piledriver chips have. I hope that this reply gets attention because I'm overclocking with AM3 board, not with AM3+ board.

Wow that is really impressive. How is the performance on that Motherboard.. When you get your parts back and set back up, could you post as screenshot of Cinebench 11.5 with your score at 4.8Ghz.
