Benchmark Scores | A LOT |
I found the option in bios to OC my EDRAM as well as disable it. I chose WatchDogs2 as my benchmark because of how CPU dependent that games is. Resolution is 2560x1440 but graphics settings are low to rule out GPU bottleneck. The results are staggering.
EDRAM @2GHz - 118 FPS
EDRAM disabled - 91 FPS
EDRAM @1800MHz is probably the sweet spot tho, it was only 1fps less than 2000MHz so basically the same, within margin of error.
The difference was 29,6%, which is huge. I encourage other 5675/5775c owners to try, as long as your boards supports disabling the L4. Remember, you have to choose a CPU heavy game, and eliminate the bottleneck of the graphics card in order for the results to be comprehensible. Use HWmonitor64 to check if the changes actually apply. It should show edram clock and temperature, while when EDRAM is disabled in bios those options are missing. XTU also can show you the current edram reading, but while I've seen it work for one review, it doesn't work for me or some other people I saw posting on intel's forum. It shows 0MHz regardless if disabled,stock or oc. Use an even multiplier like 16/18/20x, the odd ones don't apply.
