The same software installation that gave me good results with a single card returned OpenCL errors with two cards. An update to Catalyst 13.2 Beta 6 solved those errors.

Azn CrackerAren't the 7870 myst only $240 a piece?See This?
Article TextThe prices in that table were what we paid when the parts were ordered, and a lot of them changed over the last six weeks. For example, the PowerColor card is $20 less, per board. Other prices are up. All told, then, the total cost of buying our machine and replicating the build is within $20 of our original invoice.
Please call the graphics cards 7870 LE from the start, like this:
"Video Cards: 2 x 7870 LE - PowerColor PCS+ AX7870 Myst Edition"
After all, it is much more than a standard 7870.
I had no idea it was the LE until I got to the third page.

So a Tahiti-LE wouldn't be a 7870 LE, it would be a 7950 LE. The fact that it carries the 7870 model number is unfortunate, but the article attempts to make it clear that this is indeed a Tahiti-LE
"a board damaged a processor that in turn damaged every board it touched, which in turn would damage every processor it touched" and ram damaging a CPU?

That sort of thing happens once in a blue moon. Don't let it bother you.
I guess Tom's tale of woe summarizes why Intel recommends against higher than 1.575 volts on the memory controller of Ivy/Sandy:
http://www.intel.com/support/processors/sb/CS-029913.htm#4
IntelWhat are the Intel® Core™ i7 desktop processor DDR3 memory voltage limitations?Intel® recommends using memory that adheres to the Jedec memory specification for DDR3 memory which is 1.5 volts, plus or minus 5%. Anything more than this voltage can damage the processor or significantly reduce the processor life span.
In any case, the performance benefits of overclocking memory on a Sandy/Ivy platform seem so miniscule that it's scarcely even worth considering. Buy memory capable of an appropriate speed @ 1.5V, and leave it be.
(I know Tom mentions Intel's position on memory voltage on the last page of the article, but I wanted to re-emphasize it because I've seen literally hundreds of people dismiss Intel's statement on various hardware forums. When sites like Tom's Hardware push limits, even for questionable performance gains, we all benefit -- but when someone who's on a budget and might not know any better pushes limits on his own, hard-earned hardware, the results might be tragic. Tom's experiments with this stuff so we don't have to.)

Three more days rescued the content, if not the hardware...
