post #711 of 2282
I just noticed something strange. When I had my CPU running at stock speed with 16GB of ram CPU-Z correctly reported it as an i7-3960x:
http://valid.canardpc.com/show_oc.php?id=2237975

Yesterday I put in another 16GB and OC'd to 4.0 and now CPU-Z reports my CPU as an i7-3930k:
http://valid.canardpc.com/show_oc.php?id=2239857

The other strange thing as both submissions show as being rejected and ram is showing in both cases as being 4200Mhz.

Anyone seen this before? My system is running great and perfectly stable right now.

That's curious, but it probably has something to do with your CPU being an engineering sample. Furthermore it's from before the qualification sample/final stepping stage. I suspect that the Q-Spec code on the heatspreader is QB7M? It looks like a C0 stepping engineering sample of the 3960X. If you notice the specification "Genuine Intel(R) CPU @ 3.30GHz", it indicates that the programmed CPUID values weren't quite final. Final qualification samples and retail products have the full name of the CPU programmed into their CPUID registers. They would read "Intel(R) Core(TM) i7-3960X CPU @ 3.30GHz." For it's name field, CPU-Z other cpuid registers along with clocks and cache sizes to construct a less convoluted text string to display. It probably got confused because the cpuid values of your engineering sample don't quite match nose of final C1 stepping qualification samples or retail products.

Yeah it must be an engineering sample.

in your case if you look at your CPU-Z screenshot In the box stepping it says "5"

my C1 stepping 3930k has "6" in the stepping box

And CPU-Z screenshots of those with C2 stepping have "7" in their stepping box.

so logically if 6 = C1 stepping, and 7=C2 stepping then 5 must = C0 stepping aka Engineering sample

You are correct that my CPU is a pre-production sample, however when I first ran CPU-Z it did correctly report it as a 3960x:
http://valid.canardpc.com/show_oc.php?id=2237975

It wasn't until I updated the BIOS on my MB that it started showing up as a 3930.

In any case I am not really worried about it since it is still running fine, however I am curious as to why my ram is showing up as running at 4200Ghz. The first batch of four 8GB Kingston modules I was using were pre-production units as well, but the four 4GB Corsair Vengeance 1600 were regular retail product and the 48GB of Kingston I currently have installed is also final retail product.

Any ideas on this? I suspect this is the reason I haven't been able to get a validated CPU-Z

i know x79 has been finicky with a few different ram vendors and even problems with identical sets. it seems to me this is more a mobo problem than anything else. have you tried reverting to the old mobo bios u were using?

No I haven't tried that. Since the new bios has other benefits that I don't really want to give up, I kind of want to keep it.

I was really only trying to get a valid CPU-Z to join the club, but as long as my system us running properly and completely stable, that is more important

Nice to see you finally got your 3930K in and its a great overclocker! Good job!
post #719 of 2282
So does the list only get updated then when the top three change? (under additional info one first post) if that sucks I would be number 10 biggrin.gif lol

What memory kit should I use with my new x79 rig? Probably going with an 8gb kit.

are these any good? I want to be able to overclock.
