Sorry, I might have written that a little fast/confusing, I just meant the ECC part. Multi-Bit errors should be more unlikely than Bit-flips, right? And isn't something affecting the drives is why one would use RAID? All in all I just thought, that OP should read up on that topic.

So does that mean, that if you use a 1SAS-4SATA cable, each of those SATA ports only has a bandwidth of 3GB/s?

I am sorry, but that is a bit wrong. If you want to run FreeNAS or more specifically ZFS, you need to use ECC RAM! ZFS highly relies on ECC RAM. I don't know enough about it, to explain why, but it is very important for data integrity. BTW: For using ECC RAM your CPU as well as your motherboard need to support it. I don't know if that's the case for your CPU. Also what kind of data do you want to put on there? Is it important? Does the NAS have to be fast? Otherwise you don't really need FreeNAS, as the price overhead is pretty high (considering the ECC RAM and compatible hardware).

Then how can you have 1 SAS to 4 SATA cables? Is that just SATA 2 then?

I was worried, that nobody answered the questions he had after my post, but I see you handled that very comprehensively! Great post! Without ECC memory, FreeNAS (and ZFS) can not deliver the definite data-integrity they advertise. ZFS heavily relies on ECC memory. I don't know if UnRAID does too, but maybe that would be a better option. Somebody else should help you with, wether your old PC is usable for something like that, as I don't know.

Not having any idea about the RAID cards, there is a little flaw in your statement: In RAID 10 it is not guaranteed that your data is still intact when 2 drives fail. The moment 1 drive fails you are at the risk of loosing data if the wrong drive fails (33% chance). Explanation: In RAID 10 you have 2 mirrors (RAID 1) of one striped array (RAID 0) So essentially in RAID 0 you would have: A1 and B1 If one fails, all is lost. In RAID 10 you have: A1 and B1 - and - A2 and B2 If now A1 fails, there is no problem, because you still have a copy -> A2. But if after that A2 fails, B1 and B2 will not be able to help you in any way. For just a storage system I would very much consider something like RAID 6 (where 2 different drives can fail), as rebuilds of a big RAID array may take some days, during which all the drives are active and the risk of another one failing is severely higher. (Also since you seem to have a rather big budget (talking about Threadripper and the like), you might want to consider FreeNAS, as it is both speed and reliable. (It's just a tad more expensive to implement, since the ZFS (the filesystem used) relies on ECC memory. The RAID 6 equivalent would be called RAID Z2 in FreeNAS. I am currently going for a RAIDZ2 with 4x 6TB and will upgrade, if and when I need it (or if I get a good deal) to 7x 6TB with RAIDZ3 (so 3 drives can fail). Don't get me wrong, RAID 10 is great, I have a RAID 10 array of 4 3TB WD Reds in my main rig as well. It delivers faster performance than RAID 5 and is way easier to rebuild, since the only thing happening during a rebuild ist copying the data from A2 to the new A1. But as a storage system for very important data, I would not use it. Again, since you don't seem to have a budget problem, I would also very much encourage you to get a separate storage server (or NAS) rather than putting all of that in your main rig. (Maybe even better: do both for your most important data.) But above all else: a backup is key to prevent a single point of failure. All of this was kinda stitched together while watching TV, but I hope I could help you at least a little bit. BTW: Why do you need a RAID card after all? I wouldn't necessarily recommend a motherboard-RAID like Intel's, as they can be very fragile when it comes to BIOS updates, but why not go for software RAID (like I mentioned FreeNAS - or if speed is not that important UnRAID (which I haven't used yet, but I hear great things about - but also has licensing costs I believe)).

@newgeneral10 I don't have a lot of time and also not a lot of experience with this stuff, but just to make you aware: I read somewhere, that you should not virtualize FreeNAS, because, as you probably know, it runs ZFS as a filesystem. And if I remember correctly ZFS has to have total control over the hard drives it is using, so virtual drives might not be the best idea. I would highly recommend you try to read up on ZFS (or virtualizing a system that uses ZFS)!

And? Is it?

Be Quiet Dark base Pro 900

Alright, thanks for the confirmation! (That second part worries me just a little... )

Ah, ok. If they work, I'll make sure. What do you think about trying to post witht the water blocks still attached? If I only go into BIOS it really should be ok, right? Wouldn't make sense to get screws and pads if they are fried anyway.

Thanks! Will do that! Ah, that's unfortunate... Did you contact him again?

So, what thickness do you think is appropriate? https://www.caseking.de/en/search?sSearch=wärmeleitpads https://www.caseking.de/en/search?sSearch=thermal+pads So you are missing the metal part, that distributes the heat, so it can be transfered away, by the fans? Haha Sorry! Well, you have cheaper tech... But then again... Healthcare

Ah, thanks, will look into that. Does anyone else know, where I could get thermal pads, that fit the reference-design coolers of a GTX 980 Ti?

So, do you know, where I could get those pads? (And maybe some screws that are missing, too?)

Alright, but if they work I still have to get some pads, wuhich is why I wanted a recommendation. The pads offered by EK and the like all seem to be 0,5 - 1,5 mm...

How did you fix it? I am encountering problems with my Yeti, too.

Won't they overheat? I don't want to potentially kill them, if they still work. Also the pads seem pretty cheap. I just need to know, which to get...

Hello everyone, I recently got two used NVIDIA GTX 980 Tis, from a friend who had water damage in his PC. He gave me the cards, both with the water blocks still attached. He told me, I could try and see if they still work. He also gave me the stock blower-style reference design coolers that came with the card, but the problem is, that the thermal pads are either ripped, dirty or completely missing. I did some research, but I could not find an exact description of which thickness of thermal pad has to go where, or even which thickness to use at all. If anyone could help me and tell me, which thermal pads to get, I would be very grateful! As I am from germany, one supplier here, which at least seems like they have some variety would be Caseking.de: Search queries on Caseking lead to the following results: https://www.caseking.de/en/liquid-cooling/liquid-coolers/processor/thermal-pads https://www.caseking.de/en/search?sSearch=wärmeleitpads https://www.caseking.de/en/search?sSearch=thermal+pads They have a bunch of different thermal pads from EK and some other brands, but I still don't know which thickness to get, to attach the reference design coolers again. As for paste I would use Thermal Grizzly Kryonaut, as I still have some. (If you want to recommend any other, feel free to do so!) Thanks in advance, Lubi97

The ASUS X99 Deluxe-II works great for me! Auto-overclocked my 6850K to 4,6 GHz on one core and 4,4 GHz on all the other cores! (Using a be quiet! Dark Rock Pro 3) I have now dialed it down, to get a quieter system and because I don't really need it atm, but still: no stability issue for weeks, before i changed anything.

Do you already have the Mastercase 5? If not, going for a full tower would be great, if you can fit it in your workspace. I don't know if the NZXT Phantom 530 would be the best, but it would certainly be better on the upgradeability in the future!

There probably is.

Yes, most wireless headsets have their own sound card in the usb dongle. For example: http://www.corsair.com/en-us/corsair-gaming-h2100-wireless-dolby-7-1-gaming-headset

You might have to ask somebody else who knows a bit more about the Z170 chipset. I mainly looked at the X99. The problem you have is, that there will be no available PCIe-lane to your CPU anymore, because NVIDIA-GPUs need at least 8 lanes (8x + 8x = 16x). This means, that any other PCIe device you will install, won't have a direct conection to your CPU. This might not be a problem, but if you for example, would like to use a PCIe based SSD (keep in mind, that M.2 attached drives like the Samsung 950 Pro use PCIe lanes too) and a network card, things might be more problematic. Again I am not sure about the Z170 chipset, so don't quote me on that (you probably still will ), but I think the bandwidth from the chipset to the CPU is "only" 4x. So if all of your other connections (USB, HDDs, SSDs, LAN, etc.) would want to use more than 4 lanes together, you would have a bottleneck. Regarding the physical space: If you need other add-in cards you can got for the non-Extreme Edition, but if you don't need anything else, go for the Extreme!

Thank you! I will look into that, when I get my new PC.
