[QUOTE=kladner;444899]Won't MSI Afterburner deal with the overclocking?

I'm afraid a 72M LL run would probably take me a couple of weeks on the GTX460. I imagine there are bigger guns around here who would answer sooner.[/QUOTE]

I can use NVFlash from within linux to reflash the VBios to stock, however I thought I would give them a go on a few triple checks first to see if the overclock was stable and useful.

Oops! I forgot about your operating environment in suggesting Afterburner.

I grabbed it, it might take a week or so.

Here's an updated list of strategic DCs...

I had a little time over the last weekend and finally wired up a new feature into my query that analyzes CPU's by year/month.

The change involves adding in a cumulative bad/good count over the lifetime of the system. I had a separate query that did just that, but until now I didn't have a way to query the more granular data by month alongside the lifetime stats.

This lets me look at a particular month where a CPU might have zero good/zero bad, but then the lifetime stats tell me it has 3+ to 1 bad/good, so there's a solid chance this particular month is likewise lousy.

The list below has exponents where the ratio of bad/good is 3:1 for the month itself, or if zero for that month, the lifetime stats are at least 3:1.

I ran 4 similar checks myself earlier this week and got 3 of the 4 mismatching, so I think it's a solid approach. It should help squeeze a bit more juicy mismatches out of the available data. :smile:

Your result was incorrect, sorry about that.

Thanks for the verification. I have since flashed these cards back to stock so I am awaiting the results of the next few tests.

If problems persist with the updated firmware, consider reducing memory speed by modest decrements.

This suggestion is based on finding with a few GPUs, from different manufacturers, with different chip series, that gaming cards tend to run the RAM too fast for CUDALucas reliability. I have little detailed knowledge of Titans of any flavor, so I have no idea if they may have memory operating on the edge of stability from a number-crunching point of view.

Quad checks available
 

If anyone is in the mood for some quad checks, there are a few where AirSquirrels and I have already done 2nd/3rd checks and mismatched (I'm betting mine is correct) and we need a quad checker. :smile:

42183899
42222473
44695687

For the most part we've been swapping triple checks of each other's mismatches which works fine normally, but those OC'd card of his resulted in a handful of oddities like those above.

Speaking of triple-checks, we're down to ~ 470 unassigned triple-checks (2500 or so total including the assigned exponents). We're chipping away and the end is in sight now. And what's left is mostly in the 44M-52M range since I tried to tackle the larger mismatches upfront... the remainder should go quicker.

After that backlog is gone I'll probably just query for new mismatches as needed but then get back to the strategic double-checking (which should, in theory, give more mismatches that need triple-checks... it's the circle of life).
