i have two sm951 in raid 0 on g1 z170 , is a great choice ..
post #112 of 1703
Do you have any front intake fans in that case? Those SM951's get hot and they'll get even hotter in RAID 0. Even without RAID, they hit temperatures at which they throttle their performance, so it's guaranteed you will be hitting that... I would consider taking the stickers off and adding some active cooling near that area

I would have liked to see more jumpers to let the user decide what they want disabled to enable what, rather than being stuck with the choices that have been offered. Z97 was very restrictive in comparison, but even so, there's room for improvement.

I think they made a typo in the talk of M2H/M2D disabling SATA. A x4 SSD in the M2H slot disables ONLY the PCIEX4 (x16 length @ x4) slot, and doesn't do anything to the SATA ports, or SATA Express. The M2D slot does indeed share bandwidth directly with the SATA ports though, and therein is the trade-off.

Great analysis. I ordered a UD5 earlier today which has a nearly identical I/O configuration to the Gaming 7 and came to the same conclusion about the Tech Report review. Sadly, it took parsing through those paragraphs of their review (repeatedly!) to make any kind of sense out of the manual. It really shouldn't be this hard!

I kind of wish the M2D and M2H had their limitations switched. It makes sense given their locations, but I need 6-8 SATA connections for now, so if I buy an NVMe M.2 SSD, it's going to end up sandwiched between a pair of graphics cards. Ventilation's better by the CPU, but I can't get there until I downsize the number of drives to 4 max. I guess a PCI slot drive like the Intel 750 or something like the Asus Hyper adapter might end up being a better choice on this board. (Anyone know if the Hyper M.2 adapter works in a non-Asus board?)

I'm also a bit confused by the footnote in the manual (referencing slot M2D) that says "The PCIe x4 SSD runs at x2 speed.". What's up with that? Does that only pertain to an x4 drive connected with a SATA Express connector? Their product page pretty clearly casts it as an x4 slot with 32 Gb/s bandwidth, so that's the only interpretation I can think of that makes sense.

I considered X99 (in response to Bojamijams above), but my impression is that a number of things with system architecture are evolving or unknown right now (# of CPU cores, NVMe, DX12, VR, HBM, Optane) which makes me less confident in a high-end build. Z170 isn't ideal either, but I feel better about building mid-range now even with some compromises and hopefully seeing things converge into a platform with fewer tradeoffs in another few years. I'm coming from P55, so a Z170 board and a 6600K are going to be a real treat regardless. Waffled between the UD5, MSI Gaming M5 and Asus Pro Gaming, but decided the UD5's compromises were the best of the lot. Also, PSA that there's a Newegg email coupon for 10% off and a $10 rebate right now that knock the UD5's price down to ~$161.
post #114 of 1703
the best so for i can do is 4.4ghz on my 6600k using the pre-built overclocks.
has any one figured out the fan control (SIV) app its doesn't start up with win 10? it doesn't remember the settings also.
the bios fan control sucks!!!!
tried speedfan the board is not supported.
so far the gaming 7 board has been a disappointment.. should have done with Asrock or Asus

Tell me about it! I have studied those Z97 motherboard manuals and ASUS are really bad, whilst the others fair better. None of them are really plain, simple and obvious for what's going on. Why so many typos? Did you see the diagram the Russian? review managed to coax from Gigabyte regarding one of the Z170 boards? It was a butchered Z97 diagram, complete with DMI 2.0, a single SATA Express sharing bandwidth with something else and all sorts. It was worse than useless because it's just adding to more confusion. As a consumer, we want to make informed decisions, and it's damned hard to do that when we have to try and trace the freakin' circuit board from some iffy online photos!

That'd be quite a nice idea, but I guess for that to be possible they have to put in a bunch of PCIe lane switches, and the distance between the two M.2 connectors and the fact there's a whacking great PCIe GFx socket in the way may cause some headaches for the design teams - hence why it wasn't done, oh yeah and cost!

It'd be interesting to find out if the ASUS adaptor works. I wouldn't be surprised to find a StarTech variant sometime in the near future, they have a lot of little adaptors and such like.

I see the foot note staring right back at me there! If you look carefully (with a bit of zoom) you'll see the note refers only to a RAID for a card in M2D and using SATA Express with a drive in SATA_01. In other words, you should be able to RAID using both M2D and M2H with x4 PCIe SSDs and use SATAExpress_0 but M2D will only tun in x2 mode for that. I probably made no sense, and have done what those reviews have done, bamboozle! Anyhoo, It's just a relevance to PCIe SSDs in both M.2 slots using RAID whilst trying to use SATAExpress as well. But who's gonna do that, right?

Well, my current rig is an E6750 with 4GB RAM and a shoddy 8500GT 512MB Silent, so going to a 6700K with 32GB RAM and a R290/R390 and a couple of SSDs will be otherworldly different. I don't upgrade my rig very often! I like it to last.
I can see myself using 6+ SATA ports, and that M2H allowing for a PCIe SSD for use as a scratch disk or boot drive could make things rather interesting. I'll only be running 1 GPU. I do fancy trying to heat sink on the PCIe SSD just to stop it throttling...I don't really want another noisy fan!

Couldn't agree more. Trying to triage between motherboards is maddening because comparison engines only facet on the most superficial differences. Board A is $30 more expensive than board B? Time to download both manuals. /grumble

I'm hoping that once the Samsung 950 arrives there will be some reviews of the difference between deploying it in an on-board M.2 slot and a HHHL PCIe slot adapter card. If there's no compatibility or latency penalty, then the airflow difference could be significant in avoiding any temperature-based throttling that it may need to do.

Well, the note is in the top-most table too, but either way it seems most likely that it's just explaining that if you do something dumb like using an x2 connector with an x4 drive that you're going to be limited. If it turns out to be something else, I won't be very happy given how Gigabyte pitches it, but it's not the end of the world as this board still gives you a lot of options.

You won't be disappointed! I started shopping for another 5+ year build, but decided to step it down a little (6600K) in anticipation of the next HEDT refresh addressing some of the current I/O evolution concerns and hopefully there being more clarity about what the CPU requirements for gaming will be. It could be another 5 years of 4 cores and 5% IPC increments, but I really hope not. Regardless, Z170 has a lot to like, and 4-5x SSD performance should be spectacularly gratuitous.

@CuriouslySane
Absolutely, it really does mention that note in the top non-RAID table too! Oops, I missed that!!! Looks to me like it's only to do with using the SATA Express though, which makes sense as that'd use 2x PCIe lanes. Would have been much easier if they actually put crosses in those boxes rather than a tick, as it states underneath that x2 PCIe SSD will work with SATA Express.
What is with the single cross in SATA_0 with a SATA HDD??? Do they mean you can't actually put a SATA drive in the SATA slot? I think they just plain goofed that table up. We've gotta try and make the most of it, and work it out from what is a bit of common logic, maths and some PCB tracing....why is this made soooo hard?!?

That would be an interesting comparison with the Samsung 950. I can't currently see any use for an x4 PCIe slot, except for Thunderbolt (well, there's an RME audio interface that uses Thunderbolt, a couple of Focusrite audio interfaces now too) or for an adaptor for PCIe SSD, oh, or of course for a 3rd GFx card in CrossFire 'cause SLI ain't gonna have a slot that's less than x8.

I hate to be the bugger that sits on the fence, peering over the horizon and wondering, but that's exactly what I did with the 4770K. I was looking at that and the 4790K came out. Now we're at Skylake, I wouldn't be suprised to find myself actually buying Skylake-refresh (is that Kabylake?) and the refresh motherboard with maybe a few nicer features. I take a very long time to ponder that the world carries on moving and kinda leaves me behind. I guess I should start looking for a new PC literally as soon as I get one, that way I might have a chance of staying semi-current biggrin.gif

Judging by the popularity of X99 and the 5820K over Skylake, I can see Intel shifting to 6 cores as a mainstream flagship chip in the not too distant future...but we're getting itno speculation territory here, and there's plenty a forum and thread with that kinda thing in it, and an unhealthy boat-load of arguing that goes with it wink.gif

That one actually makes sense I think. The table is talking about what happens when you have a SSD in M2H. If that drive happens to be an older SATA model, then it's going to steal the lane from one of the chipset SATA ports.

I'm very much looking forward to seeing how that bet pays off.
