You just have to keep doing some adjustments, but it's not at all impossible. Take the Radeon HD2900XT, which was manufactured with 80nm tech, then the HD3870 was manufactured with 55nm tech, and then the Radeon HD5500 and HD5600 series, which has 320 or 400 shaders and is based on the same architecure, is made with 40nm tech.

0x101...the watch dog. That is one the few BSODs that pretty much never leave any doubt as to the cause. 0x101 means you have an unstable CPU or is otherwise unresponsive. Something every one on this forum should have seen coutless times. Could be clocked too high or not getting fed enough power. If this is stock settings...then this is bad...really bad.

Sucks that some one would need to mess around with anything at "stock" settings, but my guess is that stock settings is really an unstable overclock on some CPUs, but the higher clock at lower vcore just made the CPU look better or worked on the CPUs they happened to test.
Wasn't there an AMD release earlier this year saying the stock speed of the Bulldozer flagship was going to be like 2.8GHz or something? Meh...I can't find anything official, but there was leaked CPU-Z's in May that showed an ES chip at 2.8GHz. I might have been thinking of that.
lol, that "undercl...undercl...undercl...*error word not in vocabulary*" made me laugh.
Yes, I also recall reading that Bulldozer would have lower clockspeeds. Maybe these last delays were because AMD was increasing clockspeed to compensate for the lack of performance, but given that the chip is very big, with 16 MB of cache and they don't have much experience with the 32nm process, they probably tried to get the voltage as low as they could to minimize wasted power. Probably the yields are still not consistent enough and thus the voltage they set (which is probably too low for comfort) is not enough for all the CPUs.
I recall a forum member here on OCN selling a GTX480 a few months ago and he had to slightly increase the GPU voltage because otherwise it would artifact in games. From what I recall, it was one of the first cards, and probably had this same problem; later cards came with a slightly higher voltage that solved the problem. The GTX480 has quite a few leaky transistors and the lower voltage was an attempt to keep power consumption as low as possible.Edited by tpi2007 - 10/20/11 at 9:29am
