Optimizing custom computer for engineering analysis

post #1 of 2
Thread Starter 
All,
The knowledge in this forum has helped me get started with overclocking my PC. I've been searching and referencing this informative post often.

This computer maxes out it's resources (all 64GB of ram & processing) during engineering analyses that can take several hours or days to complete. When it's not being utilized to it's full capacity it is usually running a few virtual machines as servers or development platforms.

My objective is to optimize this system settings to take full advantage of it's hardware during engineering analyses

I recently attempted overclocking the machine and it failed to boot. After several beeps my Gigabye Bios loaded with warnings of boot failure due to modifications. I loaded the default optimized settings and rebooted safely.
I changed the base multiplier from 32 - 35, and each turbo multiplier to 40.

I did nothing else and believe I should have manually configured the Vcore (set to auto). I fear manually changing this value (default auto value I believe is 1.245) will consume more energy than needed when "idle". Should I try bumping this up to 1.3 with my desired multiplier values?

After ensuring I can get my machine booted with the defaults I overclocked my base from 32 to 33 and my turbo multipliers from 38 - 39. The system seems very stable here at the moment.

If I begin manually defining my VCore does this mean I cannot take advantage of power throttling when idle?
Any recommendation on what settings I should use to make this machine a bit faster?

This is in a large Antec case with heat sinks and fans (nothing to fancy). I'm also monitoring temperatures very closely with "Core Temp"

Thank you for mind share here. I appreciate it!

Welcome, while I have no specific advice for you might I suggest you ask your question in the Intel forums. I'm sure they would be more than happy to help out.
