A Few Initial Thoughts And First Overclock.
The board setup was completely fuss free and it fired up first time with no problems.
I'm going to start with;
- Q6600 G0
- 2x1GB Ballistix Tracer D9 (Green slots - these proved to have better stability for 2x1GB DIMMS on the X38 for me).
- 8800GT
- Thermalright Ultra Extreme 120
- Corsair HX620
- Raptor 74GB 16MB Cache.
I'm going to do the air cooling first again, and then the phase later.
Once again the build quality is excellent - Nothing more to say about that, you'll just have to take my word for it
One of the things that impressed me about the X38 version was that I was able to achieve some relatively high overclocks at lower voltages than previously possible on any other 775 boards that I've used.
One thing I noticed is that the NorthBridge core voltage is slightly higher at default than the X38 (1.205v vs 1.211v). This
may mean a slightly higher
NB temp, but not by much.
Keeping that in mind, my first overclock was to be 400x9 and the aim was to get Wprime 1024M/OCCT/Superpi 32M stable at less voltage than I managed on the X38 (1.3256v) -
Doable?
Yes, it is doable!
400x9 3600Mhz 1.31v 800Mhz RAM - All voltage settings at default apart from the
NB voltage at 1.35v and DRAM voltage at 2.19v.

I couldn't go any higher at this voltage.
Admittedly 0.015v isn't a huge amount, but it's an amount that I wasn't able to do on the X38.
More to follow....
