only thing that concerns me... smells like a voltage cap

They also need to add the C1 USB3.0 S3 Sleep Mode error.

They fixed it but stated it won't roll out until August or September I think it was.

That's why you follow my number 1 rule for CPU purchases, NEVER buy on release day. wink.gif

Later steppings are always better. I can't confirm or deny the stability of this chip, but newer Ivy Bridge chips are clocking a lot better.

This is with an H100.

I recall coming across a few threads in which the OPs' CPUs had start to break down. They noticed they had to either increase voltage or decrease clock speed to make it stable again, and those measures lasted for few weeks to a few months. This was especially true for a certain P4 model, where after a certain level voltage, it was guarantee to fail within several months.

If you need 1.6V to hit 4GHZ, RMA the chip, I've never seen anyone require that much voltage for 4 GHZ.

Agreed. I always seem to adopt CPUs about 8 months to a year after everyone else.

What about mobile chips? I plan on getting a new laptop during the Back to School sales.

It was an exaggeration to poke at the "crank up the voltage and turn up the fan" mentality. I would've tried to dig up and quote it if I did come across such statement a while ago.

Could be one in the far future if AMD continues to flounder. Nividia capped their GPUs' voltage citing that they don't want to deal with the RMAs. I believe the cap also affected the 690. Not sure about the Titan.

Intel has a good reason to cap voltage as well. Limits RMAs, thus increase profits. They did the same with IB's thermal paste heat spreader sandwich.

I had been running on a dual core Opteron 1214 since september 2007, mind you. And held off the whole PhII X4 lineup to get a X6. So I just went ahead and bought one.

I suspect it's the motherboard that holds me back, as xd_1771 had the same issue (an apparently crappy 1055T that takes a lot of voltage to get to 4GHz), and on a motherboard swap, BAM. He's able to get to 4GHz with 1.42V.


As for Haswell... Well, we will wait and see. Intel has WAY too much money to crap stuff in this level.
