Newest batch of 3570K's OCing like crazy - Page 47

post #461 of 615
Ok, was wrong on this one, I had to get it more stable to start getting the right Gflops. I had some instability issues to get past

I got a glimpse of my i7's batch no. its 3249C970 before it even hits my country. I have a feeling this ones is going to be a real OC performer

I don't remember if it is someone on this thread mentioning the big differences they're having from core1 to core4 of 10c. But I'm finding that the spread isn't that bad at lower clocks. So at say 4.2 GHZ it is like a 5c spread, but you start getting into 4.6 GHZ and you start to see the 10c spreads between cores.

Main trouble is, it seems they will be 10C hotter than ivy making temps your major draw back even on the longevity of the chip while attempting to reach good respectable clocks. The Chinese site shows it at 90C when overclocked to 4.5Ghz which isn't as good as ivy where many are getting as low as 60C on that same clock. It is actually not so worth the wait with that in mind.

Wow thanks for the links TLM-610 thumb.gif that is not good 5.1GHz with 1.40v frown.gif so what I saw before must be false redface.gif

I heard batch 323... and 324... are good overclocker smile.gif hope your chip will do good OC too.

When you think about the Haswell and how it is built especially the specs, one can actually see what is being reported. What I mean is look at the die size, its the same as Ivy but packed with more transistors which heat up, now it has a higher watt rating meaning it will yield much more heat over the same die size, to achieve really fabulous overclocks you need atleast the swiftech h220, ivy has proven to be elusive when it comes to heat management by coolers, now imagine Haswell under H220 if Ivy is already reaching H220's higher limits, are you really going to see Ivy high clocks with it? I doubt. If Haswell was comming in at 18w less like the difference between Ivy and Sandy, there may be a chance of really good overclocks occurring frequently accross chips, now I actually doubt it unless like you will once in a while see, a "rogue" haswell pulling gymnastic stunts in OC (mad crazy Haswell hitting 5.5Ghz on water at acceptable parameters for longterm use)

As far as Ivy is concerned I saw somewhere that A (5th letter in the batch) means the chip will require less vcore but yield tones of heat, the B will require more vcore and yield less heat (my i5 experience exactly) the C and D are undocumented. Am really curious to know what C and D really signify.

Got it!

C is a balance between A and B drool.gif

Batch numbers dont mean anything for OC potential.

Solely from the experience with my prior i5, I think it does. Was a B and required hefty voltage and could still keep it under control with a Hyper 212+

disagree to a certain extent..
