Buying engineering sample C1 stepping i7 3930k?

post #1 of 4
Thread Starter 
Code:
Hey guys,

Don't remember much about the ES C1 i7 3930k CPUs. Were they any good, close to the retail C1 i7 3930k CPUs in performance/heat and what multipliers did they have? Or should I not bother buying one and giving it a go?

I know it won't come with a warranty and I know peple aren't supposed to sell them.

Need a i7 3930k AMD was wondering if saving some money would be an idea here or not.

Thanks guys.

Google say the only diffrence with c1 steppeing is the lack of VT-D.ES can overclock worse/better depending on where it comes from.And remember that even if it have a locked multi then you can oc by blck. Also saw a 2490X (3960X ES) that had a problem with reading temps but OC'ed like a beast.

If it's a C1 stepping, then it should be able to take much higher VCCSA and VTT1 voltage without degradation. Something like a max of 1.3 (Air) to 1.4 (H2O) instead of 1.15 (air) to 1.2v (H2O) for the C1.

So it might be worth it?

I don't have a problem buying a C1 stepping retail i7 3930k so if it won't be much different if not at all performance wise then ill give it a shot. Fact it might take more voltage would be a plus but I do want to run it 5000mhz+ 24/7 until Ivy-e.
