Where can I lookup very specific Mainboard informations?

post #1 of 5
Thread Starter 
Hello,
i've just recently build my own first PC and changed parts already once and am about to do so again... That's partially my fault, but also kinda the develepors, cause they don't list all the details in their specifications. Right now I have an GA-G170-Gaming K3 EU rev. 1.0 board with an i5-6600K on it. Now I changed from another chipset board, cause I didn't know at that time, that only Zxxx boards can overclock Intel CPUs (and I've also read that some others do as well, but didN#t get any prove or anything, again cause I just can't find those informations black on white on a trusted source!). So I've just to my current one just to realize, that it is NOT! possible to set the multiplicator as you wish, without boundries! No! You have to go strictly by Gigabyte's implemented presets! So right now my CPU's running at 4,4GHz, which isn not bad! But since it only got 5°C hotter under full usage, than with stock clock, I of course want to give it a little more! I'd go to six.
Now, that is not the only issue with particular or not particular board. Also I am unable to change the clock of the ram! So, what is nessecary to do that? I really can't find any infromation, that you need to have ANYTHING special to overclock the RAM! Nontheless, I just can't change the clock speed...
And here's the third and biggest one, which also is my fault, cause it says it in the specs and I was just too dumb to read properly... I want to go multi GPU some time later with the RX 480, sometimes when I feel that one card's not giving enough power anymore. NOW, I know multi GPU's bad, cause of many reasons, but that's the way I want to head you really won't convince me otherwise biggrin.gif. The simple problem is, that my board runs the second (now, here it comes!) PCI-E 16 LANES slot WITH 4 LANES! Why, that is just retarded, imo! You don't wanna sell a CrossFire board, which runs one of both PC-E slots with 1/4 of its bandwidth speed! And I misunderstood the litle remark, that stated that the card runs ONLY in PCI-Ex4 mode on the second slot with the card runs with PCI-Ex4 on the second slot, if the PCI-Ex1_3 (so the third PCI-E 1x slot, which is truely a 1x slot, even form factor based) is populated. When in reality the second PCI-E slot runs actually ONLY with 2x, when the PCI-E_3 slot is used! That sounds confusing to you, whixh may result of me, being not so clear here, but to put it simple: In a 2-Way-CrossFire configuration, the second PCI-E 16x form factor slot runs with a max bandwidth of 4x.

SOOOOO! Now I'm about to switch again, and I want it to be the last time! I'm lookingat this MSI Z170-A PRO board. IT HAS AAAAAALL I NEED! I am very certain! EXCEPT! The mentioned above!
SO: In clonclusion: tl; dr: How can I KNOW? FOR SURE! That this particulr board can OC my CPU, if it can OC my RAM and WHAT are the bandwidths of the PCI-E slots if both are used?

That depends on the motherboard. Z170 with SLI certified or not. If it does not have Nvidia SLI certification then you can bet that both the PCI-E 16x sized slots will definitely not be at least 8x each. It would be like 16x first slot and 4x second slot.

Ones with Nvidia SLI certification on the product page means that the 2nd 16x sized PCI-E slot runs at 8x speed as it has the 8x amount of pins required.

You can google the chipset specifications online to see if they support overclocking or not. While there are some H170 motherboards that can support overclocking that is limited and can be hard to find one / or even proof of it working on a certain board.

When a chipset does or does not support overclocking it applies both to CPU and RAM. Multi-GPUs setups aren't too bad if you can get the GPUs at a good price and are not using two low-end cards like 2x 270X.

Plus the product page usually tells you what the motherboard supports and PCI-E lane info.

thank you, very much for your reply!
so yes, after looking up some mbs specs, it seems like every crossfire only mb has only the capabilities to run multi gpu in a 16/4 mode (atleast all the lga1151 and ddr4 ones)... now, if all do it? is it actually alrioght? i mean, why would u buy such a board? you just use this pci-e x4 for whatever card only uses only 4 lanes (so im not speaking of gpus), but WHY!?!?!? do you have to ad the board with crossfire compatibility if its seemingly not wqrth it???
its so frustrating! i really have to get an sli board now to go crossfire with a somewhat normal outcome? really? is there no board which would suit my needs? cause an sli board would cost me 40 € more ATLEAST! and then id get real big trouble affording a new gpu in august! btw, im planning on buying a rx 480 powercolor and later when ive enough money stock it up to two of them, therefore the whole crossfire thing here... i really cant go sli not gpu wise i mean!

oh, its the ga-Z170-gaming k3 eu rev. 1.0 with f2 bios. i made a mistake...

Sorry to hear, man!

This can happen to anyone.

Check your options to upgrade or switch the board later.

PCIe 3.0 at x4 is pretty fast though. You might not see the difference between x4 and x8 (maybe some small percentage FPS when benching?).

Take a look at this: http://www.guru3d.com/articles-pages/pci-express-scaling-game-performance-analysis-review,1.html

thanks for the link. but im not quiet getting what they do there... id think they put one gpu into one pcie 3.0, one pcie 2.0 and one pcie 1.1 slot and compare the fps. but why are the pictures showing two gtx 980 in sli? r they running the test with two of the min sli but one capped at one time 3.0 then 2.0 and at last 1.1?

also, what do you think of this mb here:
https://www.asus.com/de/Motherboards/Z170-PRO-GAMING/
i could buy it used for a loss 2€. my current mb is actually used as well, and its working great! we have this great shop alternate.de, which sells those outlet articles and they work technically without problems, atleast they claim that and i have one article that proofs that atleast, also they give u the oppurtunity to give it back within 14 days without any reason (if its above 40€) and the general 2 years warranty which u get on every sales contract that u seal by buying anything really. not advertisin here or anything.. biggrin.gif
in all seriousness: does this board fit for two powercolor rx 480 8 gigs in crossfire x8/x8 mode?
