So, I think I have peaked my FX8230. I'm running 'stable' at 5.008GHz. My voltage is a bit shocking, needing 1.625v (up to 1.68v during full 8 core load tests). My temp is at my personal limit of 65C socket. The odd thing is that I do fail cine bench and aida64 FPU tests miserably, but if I don't add FPU based instructions, I can run stable load tests all day on prime95 or aida64. Apparently, the FX8320 and others in the line, have a 'weak as shit FPU'. They need insane amounts of voltage for FPU based instructions (ASX). I can only assume that due to better manufacturing bins, chips like the 8350, 8370, and 9xxxx series will perform with slightly less voltage, hence allowing them to overclock even higher while using insane voltage levels. That last 120MHz from 4.88 to 5.008, required going from 1.53v to 1.625v. 4.7GHz to 4.88 required going from 1.39v to 1.53v! So honestly, I probably won't leave it at 5GHz, unless I can get some speed stepping to work well, while OCed, and not affect peak perf. At least with AMD, I've got nearly all the BIOS controls from the OS, so I won't have to reboot when I want to make a change.
interestingly, this OC journey has led me to discover a problem with 'starting GC3 with a huge number of factions' while overclocked. More on that in another thread.
so, here are my performance results, using the save game from the original post. Note, to do apples to apples comparison, once loaded, I immediately type in soak in debug console. I then go to research and just hit DONE, hit space bar on all idle ships, and shutdown the 3 idle shipyards. I then wait 3 minutes, to make sure the AI has finished what it might have been doing just after load (Hence the first turn will be much shorter than others). At this point, all I have to do is hit TURN, and sit back and watch the clock:
503 CTD at 11s into turn
about the only thing my 8 cores are actually good for now is cooling. Because my load at 5GHz is now hardly over 30%, the CPU socket temp is barely getting to 50C with my h100i GT. yeah, I like the water cooler a lot, but it's software is absolute crap. It's quite basic though, so doesn't have to be perfect. The radiator surprisingly never gets warm, and if I disable radiator completely, I only lose 5-6C on the socket temp. So, I basically just keep the fans on minimal speed unless I crank it up in a game. However, BEWARE of installation issues. It was a royal bitch to get my WC installed. Not enough room between mobo and top of the case. In fact had to install my WC Fans on top of the case, leaving the radiator alone in the case. I've read complaints of peeps with corsair cases not being able to fit the corsair WCs, even though corsair said it would fit!! But except for installation issues, it's WELL worth it. I can't make a direct comparison, but I'd estimate that it has dropped temps by 20C under 'normal use, and has opened my OC limit, giving me up to 500Mhz more speed (albeit with voltages that will depreciate the CPU faster, by how much, no one can say exactly). I would say next to an SSD upgrade, this is the best thing you can get to upgrade PC performance.
