Asus x99 Deluxe BIOS Ver. 1305

slight base Vcore increase

So many BIOS Versions have been released by ASUS for the x99 Delux series. What you might experience with 1203 and 1305 is a slight increase of “base voltage” on the Vcore.

When i keep using my old offset values (0.24 V) for the Vcore i do get 1.3 V on that i7-5930K. Pre 1204/1305 i did get 1.28 V.  Thats an increase of 0.2 V just by updating the BIOS.


CPU seems to respond better to what you throw at it

What i did also notice is that the CPU does respond, let’s say, more accurately to the frequencies and voltage you put through. It feels more straight.

In the past i could clock the CPU to 4.6 GHz @ 1.3 V and were able to boot and use Windows. That’s no longer possible. I would have to add quite a lot more voltage ontop of it to get it going at these settings.

What did the board achive so far with 1305?

Currently (02. feb. 2015) i am at


CPU freq. RAM freq. Uncore freq. CPU Vcore RAM Vcore Uncore
4350 Mhz 3070 MHz 3584 MHz 1.32 V 1.35 V 1.2 V


I just started to play with it and will slightly decrease the Vcore. I am still using offset values. Go Offset!




Old sad story – prime95

After all the trouble and questions we had regarding prime95 and Hasswell-E. I decided to run prime95 tests with the Kraken x60 at “silent” and at “custom” mode.  I noticed that Core 0 is behaving quite unimpressed – because the Worker 0 in prime95 stopped stressing the Core for unknown reason. Kraken x60 is a ready-to-use watercooling solution for noobs and lazy people. However as you can see in the bottom box in Kraken Cam, the temperature peaked at almost 90 °C (86 °C) with “silent” configuration.


BUT: this was NOT a prime95 HEAT test. Keep that in mind. Just ordinary stress test.


So i started the prime95 test again due to unknown abstinence of Core 0 and the temperature peaked at 78 – 81  °C.  Fans are NOT at 65%, Kraken CAM is fooling us here.



LED of your Kraken Heatsink lit up 24/7?

If you want your LED flavoured Kraken/Watercooling Heatsink to not glow when the system is powered off, change the ErP Setting in the BIOS to “S4 + S5”.

I still use Kraken x60 standard Fans. I do want to change those since weeks, or months but never completed this task yet. Maybe you can recommend some.
