hi everyone,

this is an excellent forum with some well clued up members, a real wealth of information but something i cant find an answer to is a problem im having. im building two 4 x r9 290 altcoin mining rigs and im having some difficulty. im getting no signal to my screen, not just black screen but no signal and on start up one long beep fallowed by 3 short beeps (gigabyte beep bios say faulty keyboard but im sure my keyboards good...) hdd led flashes 1 long fallowed by 2 short flashes about 20 seconds after start up. cpu fans spin and r9 290 fan spins. i have a hdmi from gpu to screen, i have double and triple checked connections, tried switching all 4 x 4gb ram in different slots one at a time two at a time and tried switching gpu slots and tried all 8 gpus. i removed the cmos battery over night and also shorted the cmos jumpers to reset bios but still no signal. im not sure if the rig is reaching bios because i have no signal on screen (just a box saying no signal). i think im starting to go insane... lol

gigabyte ga-990fxa-ud3 motherboard x 2
Kingston 4gb ddr3 1600 ram x 4
ocz gold power supply 1000w x 4
r9 290 sapphire x 5, r9 290 gigabyte x 3
amd sempron 140 and 145 cpu (one of each)
raiser cables x 8

will gpu display graphics without drivers being installed?

this is my first build so im a bit of a newbie but i used anti static wrist strap and have made a frame mdf board and 18x40 timber which holds the rig, if anyone can please help me solve this problem i will show my appreciation by sending some litecoins your way

regards

first i would just try setup on card in the rig only... then see if it boot up..

later after finis all driver/os instal then i ad the next card. fire it up and if it fine add another card..

i don't know if it capable 4 cfx or it just capable for 3 cfx

edit :
after reading the mobo web spec.. it can only handle 2 cfx u gonna need better mobo for 4x cfx

That motherboard only supports 2 graphic cards per motherboard, so putting in 4 is not how it should be.

Next thing is that you cant possible get rid of all the heat efficiently enough, i do recommend XL-ATX motherboard and XL-ATX case.

Aerocool X3 predator is a good one which gives space for 4 fans directly next to the GPU's

yup

UD3 = 2 way CFX...
UD5 = 3 way CFX...
UD7 = 4 way CFX... ---> this what u need..

I would rather go with an ROG from Asus: http://rog.asus.com/tag/4-way-crossfire/

but i still stick with the fact that an XL-ATX is the way to go, im about to start doing litecoins as well and this is the reason i opted for an XL ATX case, even though i see you made your own construction?

darn i didnt know i couldn't handle 4 gpu's with this board :( 
i have set one motherboard up with just 1 gpu and tried to booth it and no luck, it just wont give a signal to the screen. all i get is 1 long beep fallowed by 3 short beeps. im stumped...

it should project the bios on screen with no drivers for the gpu right?

i was thinking of setting an extraction hood over the gpus attached to an inline 150mm rvk fan with ducting and extracting the hot air right out the window. it gets really hot where i live and that kind of heat building up in the room could turn the room into an oven.

I am affraid you do have a problem: http://www.computerhope.com/beep.htm
Did you check manual where to place the ram in correctly? Like ussualy its Ram-empty-Ram-Empty slot.

It could be that you have shorted stuff out because you tried to put in 4 cards in a 2 card motherboard, and those are not just any cards those are absolute hogs. I personally would never ever go with R9-290's, even your PSU's are 1000 watt, i dont know if they are atleast gold rated but you can barely or cant pull it off with 1000 watts, your looking at a seasonic 1250 watt Gold rated PSU.

I wish you would ask us sooner or did a bit more research before purchase! i feel really bad for your mispurchase alone!, hope it still can be fixed as easy and quickly as possible.

oh and i have 2 1000w psu for each rig so it should of supplied more than enough electricity to fry my hardware...

i think i might go gather the power leads from the rest of my fried hardware and hang myself with it lol

your exactly right i put the ram in the wrong slots, thats what i was afraid of. i put them side by side with no space in between, i was so keen to get mining i just rushed it. this was my first build. im truly gutted i think ill go get 4gb of ram tomorrow and try it in slot 1 with 1 gpu and pray it works. its more than likely fried the ram, its very sensitive right?

Then go buy 2x2 Ram and not just one stick, but as youve seen in the link ive given to you, you have a high chance that more is destroyed. May i recommend for you to go to a PC shop and let them fix everything? i knew you were rushing lol! i am like that myself too, took my half my life to get it a 'bit' under control.

Ram is not that fragile, i am recommending this course because you clearly lack skills to make such a PC, i believe that even if you would get that new Ram it just wont fix everything. Go to a PC shop and give them that extra money and tell them fix it right now!.

Your cards refuse to mine for you. That's the problem.

????? i only gave good tips, you want to put in one Ram stick into the motherboard but thats a thing from the past, you always need 2, You could download MEMtest and run it to see if your current ram is fine, if you have a working PC where you could stick them in.

i dont mean "no way" as in im not bringing it to a pc shop i mean "no way" as in im in disbelieve i could of fried 6500 bucks worth of hardware haha... wouldn't the board of taken the impact of the extra voltage and not the cards surely.

if you remove the ram from a pc and run it with a gpu will it display a screen or will it give no signal?

It wont do anything, have you tried it on one PSU, the RAM in the proper slots and one GPU? have you checked the manual if everything is connected properly? does the CPU fan spin? does the GPU fan spin?

and yes it is possible that a shortage can go through the ENTIRE system (have seen many PC's which shorted out), but lets be positive here. By placing the ram int he wrong slots it should be fine, but you pulled off a combination of wrong RAM placement and placed 4 GPU's in a motherboard that can barely handle it.

u have 2 board 2 set of PSU that could helps in trouble shooting...

ram position should not be a problem, it should boot up..
in fact using one stick in each diffrent slot in memtest is recommended to check slot problems

If the board still don't light up with one ram, one gpu, then we need to back to basic...

dis assemble everything...
do bread board test,
follow the tom's hardware step by step trouble shooting guide...
(it already compiled and very good at explaing things, better than me at least :D )

so its damaged the ram then, it cant possibly damage gpus from putting 4 cards into a board thats built on a 2 crossfire system.

done the bread board test, all configurations giving the same 1 long and 3 short beeps so it must be the ram thats bad

dose this sound right?

have u test all the ram stick (one stick at a time) on both mother board?
it's unlikely it all burn out...

yeah i tested all the ram in slot 1 both boards and same with gpu's with same result. i ended up testing the gpus and ram on another board round at a computer wholesalers round the corner. all working no fried parts few... and i tested the board with another ram and a different gpu they had there and the boards fine to few...
so the problem was the bios that was factory installed on the board is not registering with the r9 290's. i have to use an older gpu to update the bios and then ill be able to use 290's but i wont be able to do for a couple of days when things open up again after xmas.
so it was just a bios problem in the end, no hardware damage which is a weight off my mind

thanks for your help everyone its much appreciated :)

Good! nice to hear, the long bleep and 3 short bleeps ment you had a problem in the VGA circuitry which is true even in this case. Good thing you know now how to install Ram properly lol! else youd be back with problem 2!.

Let me know if your litecoin machine will mine the estimated by you, i just started litecoins.
