i7 950 worth getting? - Page 2

And to the OP. I have a 950 and I can say that it hasn't let me down yet. Got to 4GHz @ 1.28v. In all honesty it probably can go lower but I don't feel the need to go through all the hassle of lowering it until I get BSoDs.

I think my plan would be to either buy a used 920 or get a new 950. Of course, if I do get a new 950, there's no guarantee I won't get another crappy vcore eating one. However, if I can find a seller who wants to sell their 920 that OCs reasonably well, this would probably be the best.

At first glance I'd say no.

What problems are you having overclocking your current chip? Typically some chips require more volts than others but with good cooling you should be able to get a good overclock out of that thing.

Essentially it typically represents the evolution of processors. The first letter usually indicates a major change they made while the number is minor. Normally they just choose the next letter in the lineup of the previous processor.

As to what was changed, that is normally indicated in the white papers they release prior to every CPU launch and varies with every CPU. Normally though a letter change means a physical change on the die itself while a numeric change indicates a software change/improvement.

It's a revision level.

950s only ship as D0, where the 920s had both C0 and D0.

That batch of "golden chips" was from the D0 revision.

Every chip is unique, the VCore it needs for a given clock, multipliers it likes, VTT it needs, etc... even within the same batch. Because one chip in a given batch runs 4.4ghz at 1.1v doesn't mean another in the same batch will.

I'm running my 950 at the 21x multi and a 208 baseclock because it wasn't cooperating with the 23x, essentially running it like a 920 with turbo off.

I'd get any i7 920/930/950 you find the best price on and roll the dice(because you're rolling the dice no matter which one you buy), it may be a good chip or may be average, you'll only know once you start OCing it.

Last I tried for 4ghz, it was at 1.35vcore. After OCCT for an hour and a half, BSOD code 1xE1. Although my temps were staying around 75-77 on 100 load, at times it would jump to 80-81. Tried 1.355 vcore, OCCT 1 hour 50min BSOD same code. Tried playing with QPI and VTT endless times. My chip wants vcore bad.
