hmmm lol i guess you dont know why i laughed.

but there is no such thing is laser thermometer.

What you have is Infared Thermometer with Laser pointer so you know what you're pointing the meter at.

Thanks for the laugh.

Why don't you just fuck off, you know *exactly* what I was talking about, and you have shown your preference for smart-arse masturbation over any real content. Of course there is 'such thing is laser thermometer' (sic - and yes, I laughed at your infantile grasp of English grammar) - it is the most common terminology used for laser-sighted devices that measure temperature by means of black-body emission (which, at human-range temperatures, happens to be in the infrared wavelengths of the electromagnetic spectrum, as you read on Wikipedia). Try Google, you won't find a load of 'no such thing is laser thermometer' comments - you'll find sites selling the devices and descriptions of how they work.

Looks like I've wasted my time yet again - trying to be reasonable in my responses to yet another child on the internet pretending to be (a) dominant, and (b) intelligent. You are clearly neither of the two, and also have plenty of other deficiencies - it is as clear as the summer sun.

I'm not actually breaking the intentions in my previous statement - saying I wouldn't defile myself by debasing myself to your level - in this case I'm happy to go further. I can't see you having the courage to behave like this anywhere other than on the internet, you are a snivelling little worm. If you think that 'correcting' *me* about my usage of the *most common* nomenclature for laser-guided infrared emission pyrometers makes *you* look intelligent and *me* look foolish, then I will continue to roll my eyes and hope that you grow up in a decade or so. On the 6-sigma probability that you are an older adult, then just go pay to get a blowjob... it sounds like you are in quite desperate need of relief.

If you want to get into a pissing contest about who is the most intelligent then be my guest. I'll even graciously give you half an hour to scramble around Google and Wikipedia to attempt to sound educated. However I'm not responding to any more of your trolling. If you come up with something actually worthy of comment and discussion, in a courteous manner, then that is a different matter.

Hope this bite to your troll is good enough to satisfy you. It seems pretty clear that it doesn't take much to make you giggle like a schoolgirl - please remember that there are plenty of serious, highly educated professionals in the Bitcoin market and on these forums, and your puerile attempts to wind people up simply reduce the signal-to-noise ratio. So does this post, of course, but in the absence of any ability for instant retribution (you're hiding behind your keyboard, and if I decide to go back 30 years to when I was a blackhat for the lulz, it will still take time to do a clean job), a rude forum post is the only option.

Have a nice evening.

Pretty useful and inexpensive tool - I think they're brilliant...

Not sure. However I *do* know that daisy-chaining PCIe extenders works both for low-power cards like the 5670 in this pic, and the overclocked 5830 in my second frame rig. The frame rig has an x1->x1 extender daisy-chained to an x1->x16 extender, no Molex power augmentation. And it works fine.

I haven't tried more than two extenders chained together - I only did it because I had to. In the case of the Antec case (heh), the 5670 had to go in the drive bays to have a second fan blowing air at it - so extra length was essential. In the frame rig, I wanted the hot dual-slot cards to be spaced equidistant to get decent airflow. Check out the 'show us pictures of your rigs' thread (the 'other' one with the mad open frame stuff) for my double-logic-board twin-PSU 6-card frame - ensuring all 6 cards get fresh air meant that the leftmost card's extender wouldn't reach any logic board PCIe slot. So I used two extenders.

Given that the 5830 has two PCIe power lines from the PSU, the real proof of the concept is the 5670 in the Antec case - all the power that GPU pulls is PURELY from the PCIe slot. There is *no* auxiliary power feed from the PSU. It's *all* coming through those two extenders chained together... and it's been running overclocked to 900 MHz core (103 megahash/sec) for weeks now, stable as a rock. No fires yet!

I can't see many reasons to use three normal-length extenders chained together (I've used Cablesaurus brand, shipped from the US, and the 71leven eBay vendor to get next-day no-import-tax delivery in the UK - the 71leven UK extenders are, dare I say it, better build quality than Cablesaurus) unless you've done a NASA on your frame rig design and mixed up centimetres and inches (sorry, couldn't resist)

However please note that I don't own any cards more powerful than the 5850 series. The 5850 is alleged to be more power-efficient than the 5830, so my overclocked 5830s (hell, ALL my cards are overclocked, so it's redundant mentioning it ) probably suck the most power. But even if my juiciest card eats 200W, 150W will be taken from the lower-resistance direct-to-PSU feeds, and the remaining 50W from the PCIe slot (this is my understanding - happy to be corrected by any EEs here). And I don't really think *any* of my cards are *really* pulling 200W.

If you've got some monster dual-GPU card like a 5970 or the big 6990 (?) things, there's a good chance that the card will pull the full-fat 75W max spec power from the PCIe slot as *well* as the full power from the auxiliary power feeds. And my daisy-chained unpowered PCIe extenders may melt and catch fire with 75W but not with a max of 50W. Remember that's 6.25 amps through those thin-gauge ribbon cables (yeah, they are duplexed, but 6.25A is lots of current for such a thin wire), compared to my theoretical maximum of 4.16A. At the very least, it'll create enough resistance to cause a noticeable voltage drop on the supply via the PCIe slot. YMMV.


IMO if you're running a heavy-duty card (compared to my mid-level cards) on x1->x16 extenders, or worse, daisy-chained x1 extenders, then overclock the card and monitor the temperature of the ribbon cable with a laser thermometer. If it gets too hot (cable max temp spec is often written on the cable) then try a different approach (or use Molex-augmented extenders)
