I have just received a 'Cryo Tetrad' PC from cryopc.com. They came recommended, building stable systems with good customer service.
I opted for the 4.7Ghz boosted 3930k specifically as I wanted AS MANY threads available to 3ds Max as possible. My query is that both 3ds Max and CPU-Z recognize only 6 threads. Everywhere I have looked online shows the i7 3930k to have 12 (Two per core as all Sandybridge chips). For example my i7 2600k system has 4 cores and 8 threads available.
Anybody have any idea what may be going on?
Thanks in advance for reading and your help is greatly appreciated.
Yes, it will impact performance. Your intended use is precisely the kind of scenario where hyperthreading is a benefit. I suggest going to the bios and turning it on. This might affect the max achievable clockspeed but hopefully not.
I have run some Performance Test benchmarks and it seems to be no faster than a standard 3930k @ 3.2GHz and only very marginally faster than my i7 2600k at 4.5GHz!
I will have to wait for a response from the vendor as I don't want to mess around with the BIOS, especially with the 4.7GHz clock speed they have set. Why would they sell the idea of the ultimate in processing speed and then make it slower? Hoping there is a good explanation as this is not as fast as I was expecting
I have found something in the documentation which actually states that there are two profiles set up on the system. One is a 4.6GHz with HT disabled, the other is 4.5GHz with HT enabled. This is the one I need for rendering images!!
My only problem now is how to load these profiles. Is it done from the BIOS or within windows?
I'm sorry if I'm asking silly questions, I'm a 3D artist, not a PC builder!
Once you boot into the BIOS (press Del key) - click on M.I.T.
Now find Advanced frequency setting \ Advanced CPU Core features.
In the list you should see "Hyper-Threading Technology" Make sure its on Auto, if it's on Auto, try changing it to "On".
I'm wondering if your HT is disabled due to your high clock - just be warned i'm not sure how your system will react with enabling Hyper Threading (might de OC your CPU, will probably give higher temperatures as well) - although it should work no problem.
