I would first see if the BIOS needs to be flashed.

Well, no luck, I was on bios 1.13 already, the update didn't solve the issue.
I guess I'll contact EVGA to report the issue and hope they solve it quickly to get my data back !

yes I flashed to 1.16, anf it is a new build (but the 6805 worked fine in my previous build). The 6805 is also flashed to its latest bios.
I already had that kind of behavior with another raid card on an Asus mobo. A bios version corrected the issue back then, somehow the raid card bios was messing up with the mobo bios.
I just contacted Evga support, hope they can fix it soon ...

Hello again

Here are some pics from the weird menu I c1n access only when plugging my adaptec 6805 ...

yes it's up to date
 
sorry about the double post, I thought this would have its place on the other thread

I did set PCIe to GEN2, but is it possible to manually set PCIe speed ?
Right now it's 8X apparently
 
As for graphic cards, one is at 16x and the other 8x

I'll ask that you contact EVGA tech support

I didn't want to be selfish git and bump just my post higher. Since you have same problem as me decided to bump yours. :D
 
Just to let you know. I've obtained 6805E as a half-patch work for my problem with 71605. And it works (latest BIOS out of the box). Granted it's simpler version of 6805 but it's the same logic build 5.2 instead 7.5 on 7 series. I do have 2805 and 3805 (latest BIOS, also 5.2 builds) and these 2 work flawlessly every time I tested them (unplugged 2 arrays from 71605 and connected to each). But because both are Gen.1 and SATA 3Gb/s I decided to try 6805E. (On HDDs there is no difference, but SSDs are shafted by 50%)
 
I can't provide any more data as I only did preliminary test of dozen or so boots and it only once failed (at 1st attempt and then it was smooth sailing). Waiting for additional cooler to test it properly as I can't move cooler from X58 while it's on and I was just keeping fan above AIC in one hand and doing magic on the keyboard/mouse with the other sitting on the floor he, he. My Classy is pretty much default settings, 1.18 BIOS, with Quiet & Fast boot functions disabled. No OC, Memory is only in XMP1 profile and that's it. GTX970 in first slot and 2 Intel750s in 2nd and 4th slot. I tested it in x4 and x8 (6 slot) and both times no problemos.
 
On my 71605 front I've received one bit of good news (or rather I hope it's good news in the making if that makes sense ;) ) there is scheduled new firmware for 7 series before end of July, so as you my imagine I'm already excited. I hope Jacob (yes I nudged him gently a bit) will also put something positive into the mix. I don't really need R5/6 capability anymore with fatter and fatter HDDs, but 16 ports instead of just 8 it's just better. It's higher number that for starters (LOL) and I can expand SSD array further after I dump 2 old HDDs. 
 
Just to imagine scale of the problem with 71605 I will say this. In 3 weeks of constant testing, retesting, retesting, retested, retested..... retested things I've got ONE proper boot&initialization as 71605, ONE as 71605E (yeah it gets better...), 3-4 as 7805 (!!!) and uhhh like 500 without signs of life whatsoever (excluding permanently lit on LEDs). And that sneaky thing booted once properly guess when? When I was recording movie for Jacob to show him how card behaves. Sneaky, sneaky...
 
To some extent I don't know now to move or not to move stuff. To wait or not to wait? Dam! Hoover Dam!

Wow USB issues. That's truly scary. Thankfully all ports seems to work properly for me. Perhaps its indeed faulty board somehow?
 
As for cooling I do use Titan TTC-SC07TZ [http://www.titan-cd.com/Y...vgacooler_e.php?id=891]
 
Advertised as VGA cooler (probably for mining Litecoin or whatever you do mine with VGAs now, abandoned mining like 18 months ago so not really on top of things :) ), but it doing great for RAID AICs. Biggest advantage is that you can replace fans to you liking or do L shaped cooler to push air from 2 sides at once (with pre-7 series it will work, but 7&8 it won't as ports/cables are in the way of fan). Titans aren't bad (actually very nice) but these are not of Noctua or Noiseblocker quality. With default fans it's 1 slot solution, with custom it's more than 1 slot. Availability is sketchy at best across Europe, but eBay is your friend on this matter. It keep things nice and cool (assuming using last slot) solidly below 50C which is from my point of view max comfort zone for me (RoC is rated at max 60C IIRC). To be honest I was thinking about liquid cooling 71605, but from e-mails exchanged with Adaptec it looks that radiator (hold with pins) is also glued with some industrial stuff and it may be catastrophic (not to mention warranty) if I attempt to remove it. Which is a bummer as I have waterblock which is compatible with holes and size or RoC. 

Yeah for the moment running Enermax AIO Liqtech 2 240. Loop will come sometime in the future but first 71605 problem must be solved. 

OK, just ordered the Titan to give the raid card some fresh air :)
 
I added a little 40mm fan on the 6805 when I bought it, which performed quite well with reasonable noise. At least this time I won't have to "damage" the radiator with screws to hold a fan ^^
 
Quick question on the titan : I'm under the impression that 1 fan would point right to the ROC and would then be enough, am I correct ?

Oh yes. Progress!!! I think...
 
I guess I finally nailed 6805E to work as it should. I know I said it was working but today I've got my Titan TTCs and did some in dept testing of the card (no disks). To my amazement every cold boot resulted in same thing - hang (with message that controller actually started). Restart and everything was working 100%. Did that with few BIOSes with same result except with firmware 17109 (Asus suggested to downgrade firmware because of some issues with Adatec firmware) and below I've got error messages that firmware is corrupted, but after restart everything was back in working order. Weird doesn't even cover it. 
 
Anyway finally I found the solution. In slot x4 it was working perfectly (even with 2 corrupted firmwares - windows flashed BIOS for 30-40 minutes while it actually should take about 2-3, so I just did cold-shutdowns and flashed it in DOS [FTW! Hands down best OS from MS ever], with verification). I set last x8 slot to Gen.2 and voila! Works with 8 cold shutdowns and power-ups on the bounce. Extreme yes, but effective. Now at least I have something to look forward too. I will do few cold power-ups before weekend to check that it still works. Mad, but there you go. :)
 
One slight issue with cooling is that chipset on 6805 is located in different place vs 71605 (much bigger) and as such I could do without 2 fans, but for the sake of more airflow near PCB left it. And had to slide fans max down to cover the RoC radiator. With default setup it was in left bottom corner barely getting any airflow. Anyway solved that too, and getting nice 38C.

Seriously. I don't pretend to be expert in electronics or manufacturing process of motherboards, but it looks like your board may be indeed faulty. Under normal circumstances there shouldn't be interaction between PCI-Ex and USB on a level you describe. Did you bought your Classy early? Something that is euphemistically called 'early adopter'. It may points to faulty circuitry somehow. Badly shielded track or some bogus interconnect somewhere. With some misaligned/faulty path it could be possible. After all Classy is simplest X99 board you can find. It has only what X99 specify and nothing else. One of the reasons why I got Classy in the first place. No fireworks, just solid set of controllers. Granted I would love to see 2 PS/2 ports, but there is - sadly- no PS/2 in X99 specification. Hey EVGA get PS/2 port(s) on X99 Classy#2 pronto.
 
I admit I don't have front USB3 panel because I don't really need one with 10 port Anker USB3 hub using only 1 USB3 port anyway. I was thinking about getting one (simple 2 port Zalman I've seen somewhere), but if I had to run into same issues as you do, then I can live without it. :)
 
As for you LSI card. I hope it won't fry itself. On really hot days my 71605 gets to 48C with 2 fans pumping air. And all of that with like 11 more fans inside.

OK, I've put a fan at the bottom of the case, on 4 screw + some soft tape to avoid noise, VOILA: 53°C :)

Just received my titan almost 1 week earlier than expected :)
Now that the LSI is "cool", I'll just wait for the H240X to arrive.
 
I've had another black screen with an NVIDIA driver issue reported in the event viewer, so I decided to flash to 1.18, and made some changes that should probably be nice.
I reactivated CSM, which gives me now a complete - not buggy - bios ! Hope that Windows will be OK too on that one.
 
I'll probably test front USB3, I suspect the issues will disappear, or at least I hope so !
 
What a pain ... the more I build rigs, the more I get problems these days :s
