Wow! In My Humble Opinion, you are working too hard and too late... definitely got the bug I think....

LOL!

You asked a lot of questions... well, you surely don't want to experience thermal runaway and about the only cure for that would be a case mod or change. Fact is, a 2U or 3U case may work better for you.

Most projects take little memory, others take 500Meg or more (NFS) up to 10Gig or more (Lattice) per WU. There would be a few projects you simply could not run and you would learn fast what those were when the virtual HD started thrashing. IF it was up to me, 2Gig per core would be nice... but likely most projects would do fine with 1Gig per core...

Hi Friends,


And then everything went black!!

Never in my life have I seen a worse manual!! 1 Line in the manual tells the user, that he/she has to connect this 4 pin HD connector to directly to the motherboard. I have never seen this in all the years I have been making computers. So, of course 1 line on page 4865 is more than enough. S..... M........... !!! /&%¤#¤%&/()

I'm really really sad right now! Thousands of dollars, multiple days used, and then just because of a connector which is placed by a stupid engineer, I can't go on with the test. The problem is, the connector is horizontal and there's no room for a horizontal connector. I've only got about 11-12 mm from the connector on the mobo to the edge of the 2U industrial PSU !?!?!?

Here's an image of the connector. I learned by searching the web, that this connector has to be used, if you install a graphic card. Well, of course we wan't to install a graphic card. Why would we buy a mobo like this, with 4 x SLI if we didn't want to install a graphic card.
The text/info in the manual is, "connect a hd connector to this if you install 2 graphic cards on this motherboard" !!!!! Well, do they mean 2 graphic cards in total? More than 1 card? Is the onboard graphic card included in "..2 graphic cards..."



Anybody who has got an idea???? If, please don't hesitate to let me know. I'm pretty down right now frown.gif

Well, the PCIe power specification is what they were worried about when they did that. It's just an aux connector to supply the Mobo PCIe power buss with additional poop for multiple cards. It has nothing to do with the onboard graphics...

Thing is, your cards are LOW power to begin with and MAYBE don't exceed the specs when 4 installed.

In any case, that is a ***** of a problem... If it was me, I would put a DVM on that connector and install 1 board at a time and look for a substantial voltage drop to see if the buss is being overloaded....

Other than that, there ARE right-angled molox connectors that would take up little space after installation... Look for an adapter cable maybe...

Thanks for your prompt response wink.gif

Well, then I'm, totally lost! I was sure that this was the reason the system will not boot or even go to BIOS !?!? Then I thought, well, this is maybe what they were talking about, and all I need to do is to update the BIOS to version 2.0 . But, if this was the problem, then how am I suppose to update the BIOS, if I can't even access BIOS !?!? I tried everything, other memory, change/check control/pwr/hdled/reset settings, changed PSU, keyboard etc. etc. But, I know it's non of these things, because the onboard speaker would have told me so. Nothing happens. Only installed 1 graphic card. but the screen is black and will not access BIOS. Z87 / "devil's canyon" conflict???
If, how do you update the bios without accessing the BIOS/boot-up ???

http://www.asrock.com/MB/Intel/Z87%20OC%20Formula/index.asp?cat=Download&os=BIOS

BIOS v.2.10 2.10. 7/22/2014. Instant Flash. Support i7-4790K, i5-4690K and Intel® Pentium®

OK.. That's a good idea. Then I can see when ever the voltage is not enough. But right now, we need it to access BIOS wink.gif

Maybe I should try and reinstall the CPU ???
http://www.overclock.net/t/1415886/problem-booting-with-asrock-z87-oc-formula
Do you think the problem is the CPU is a i5-4690K ??? And that I need to update? If this is the case, wouldn't I be able to access BIOS even though the CPU wasn't yet supported??


Thanks for the help wink.gif

You can also try pulling the Motherboard out of the case and connect the molex power just to see if that is the problem. If you hook up the molex power and pull all the add oncards out of the system and it will not boot, then it is most likely the bios. Your options are pretty limited here. You can try to get ASRock to send you one and cross ship it, or you can possibly go to a local shop and get them to help you?

Hmmm, well, next thing to do is pull the battery and short out the contacts for 15 seconds to make sure the BIOS is reset to defaults and try to boot again with NO graphics card installed... using onboard graphics only. BE SURE to hook up a monitor that supplies EDID info, not some old crap like I have because I have discovered that a LOT of those NEW linux base fancy BIOS setups need that EDID info.

Hi Guys,


Thanks for helping me here wink.gif I'll look into it right away! First time ever having these problems.. I'll guess on wrong CPU/or miss-fitted CPU. If not, then this power connector for extra graphic cards. Let's see wink.gif

Hi Magic, a new BIOS? But the new BIOS I can DL. But how can I update the BIOS without accessing the BIOS? I usually flash update BIOS. Thanks for the other ideas wink.gif

Did test with other monitor and keyboard. One of the first things I did. I usually have a line of things to do when solving these problems, but a black screen with no "beeps" (errors/warnings) I just didn't now what to do. But now I'll try what you suggested, both of you wink.gif

That board has 2 bios chips and they are removable. You can remove one of the bios chips and either get a local shop to flash it or call Asrock.

I would call Asrock to see if the bios is the problem. The bios version that is shipped with the board is probably on a sticker on top of the bios, Asrock will be able to tell you if your CPU is compatible with that bios and give you options. I don't know how they handle that today, but they might just send you a bios chip with the correct bios for your CPU.

Hi Guys,


SUCCESS !!! Well, I tried the stuff we agreed on and found the problem! It was the CPU! I took the CPU from another test-bench, a i5-4670K which is "Haswell" architecture and then it worked just fine. With additional graphic card and without any 12volt HD connector wink.gif

"ASRock Z87 OC Formula" and i5-4690K CPU
http://www.asrock.com/mb/Intel/Z87%20OC%20Formulaac/?cat=Download&os=BIOS
IMPORTANT! If you buy the this motherboard "ASRock Z87 OC Formula" and an i5-4690K CPU, remember to buy an additional CPU so that you can update the mobo for the i5-4690K. wink.gif
I know it's me who made an error buying this CPU. But ASRock friends, please let us know, if we wan't to use the i5-4690x and i7-xx90x CPU along with this mobo, we need CPU that works before an update is possible !!! wink.gif

I'll test the new CPU in my test bench, and if it works with the mobo ASUS Maximus VI Extreme, then I will just keep it there wink.gif

Let's continue the test. And thanks for the help Magic and Tex wink.gif

OK, this I didn't know wink.gif That's indeed a way to solve the problem. I didn't know that it was possible to remove the chipset from the board. Without a hacksaw that is wink.gif I'll look a the chips to identify this possibility and thanks a lot for letting me know wink.gif
