Hi,
I just recently bought all the parts from NCIX.
After everything installed, the cpu shuts down randomly.
I have tried using Gskill's forum in adjusting the ram speed. In this case, it still shuts down.
This is driving me nuts, I even went and memtest86 the ram and it works fine (that's after a few tries) as during the memtest86, the cpu will randomly shuts down as well.
Please advise how to fix this.
My bios is the latest version from June, 2009
I followed the instructions from this website but it still doesnt fix the problem
http://gskill.us/forum/showthread.php?t=1129
Here's the specs
Gigabyte MA790X-UD4P
Xigmatek HDT-S1283 Direct Touch 3 Heatpipe Heatsink AM2
AMD Phenom II X4 940 Black Edition Quad Core Processor AM2+ 3.0GHZ 8MB Cache
WD 640 gb black
XFX 4890 video card
Gskill DDR2 ram 1066 5-5-5-15 - F2-8500CL5D-4GBPK
I have ordered 4 more gb of the same ram, hopipng 8 gb will solve this problem... but i havnt received it yet.
Please help!!
Ive searched and it seems a lot of people have a lot of problems with this mobo

i didn't want to start a new thread, but i've searched/read/tried every possible method i could find :(

Hi, Tomy,
Quote from OC forums,
(Hello,
1600 is not easy on these AMD systems. Lower ram speed, higher NB and CPU, with tighter timings is the way to go.
Check Tony's results here:
http://www.ocztechnologyforum.com/forum/showthread.php?t=55369
Slower memory and higher NB speed beats high ram speed in performance or is at least equal, plus is a lot easier to do.
Also.. same CPU but with DDR2.. results are the same: http://www.ocztechnologyforum.com/forum/showthread.php?t=56048
High ram speed is not the key to performance.)
May be worth a look,
Regards

actually i've tried running it at a lower speed 533 mhz or 800 mhz, yet it still crashes..
should i rma the ram or rma the mobo.
this is driving me nuts

Hi
Your G.SKILL F2-8500CL5D-4GBPK RAM should definitely work OK with this MB as it has been tested, it's on the QVL:
http://www.giga-byte.co.uk/FileList/MemorySupport/mb_memory_ga-ma790x-ud4p.pdf
Installing 8GB in 4 sticks of RAM will not help as only 2 RAM sticks can be supported due to CPU limitation.
It's very strange that your system shuts down during memtest86, this definitely must be some serious failure either in RAM or MB. I can't guess which one of these items is faulty but changing RAM to other ones could help a lot to diagnose the problem. Wait until you get RAM you ordered then try with it.
Have you talked to NCIX about it or not yet?
Good luck m8
-
yes i have.
we've diagnosed the problem to be overheating with the ram.
dunno what i can do to solve it.
when i open my case, the crash takes longer to occur.
tonite, i used a big fan (those for home use) and directly blow it at the rig, and guess what, no more crash.
wtf is this? now im thinking, may b my xigamatek heatsink fan is too big that the ram in slot 1 and 2 is overheating and causing it to be unstable.
in this case, should i go back to the stock heatsink and see if it works stable? grr..

What is system temperature reading from BIOS or EasyTune6 software when you close the chassis after several (around 30) minutes of work?
If the problem happens only when chassis is closed then you need to improve airflow to lower the system temperature. Some example how it could be done you can find here:
http://www.giga-byte.co.uk/FileList/WebPage/mb_081027_x58/data/tech_081027_x58_hsp2.htm
According to my experience at least 1 additional big (12 cm) and slow rotating (=silent) fan is required at the rear, 2 (1 front, 1 rear) would be perfect, but sometimes the second one is not necessary.
P.S. If you already bought so nice and silent ::) cooler (http://www.xigmatek.com/product/air-hdts1283.php) then replacing it with the standard one may cause higher noise. But of course it's your decision if you really want a silent system or you don't care about it.
-
actually, if i don't turn on my fan cooling directly at the ram, it crashes within 10-30 seconds. so it'll be hard for me to see easytune6 in windows.
if opening the case solve the issue i wouldn't mind.
but it's just the stability concerns i have... as of right now i've dedicated this home fan just for my cpu haha using 6 gb if ram
i cant use 8 as it wont run without crashing
-
If RAM overheats pls try to lower it's voltage in MB's bios, however it may negatively impact the stability, so lower in smallest steps available.

thanks..but i dont think my mobo allows me to lower voltage, and it wont run stable if i do i guess.
is this common with the mobo + this ram?
it's funny, i tried putting just 2 gb ram on slot 1, but it wont even boot.
-
Hi,
It seems to be a heat related problem with that memory, Set it up to SPD Auto, ;)
What is your o/s To take 8gigs? you must be running a 64 bit,
Although your memory is on the compatible list, a problem is evident, ;)
I would try another make of memory, ;D
MEM test is throwing up errors with your existing memory and high temps is not quite right for it mate,
I not a techy just logical deduction from a silver surfer, 8)

i was able to run the computer stable last week using a house fan pointing at the computer.
so today i wanted to try running 8 gb instead, once i put the extra 2 gb in, my cpu is unstable again and it wont even go past bios.
after taking it back out, i tried running at 6 gb again, it wont even boot now!
please kindly help!!!
this mobo + ram is frustrating me, I really want to find out why and how to fix this.
I've tried everything, even taking every single part out and putting it back in.
Now it wont even turn onto bios now :(
when i turn it on, all i hear is the 4890's fan running at full blast, my xigamatek fan doesnt go on (it only goes on after bios turn on from previous experience)
please help!

Hi,Tomy
If I were you I would request an RMA from NCIX for the mobo and memory,
Or seek a professional repair guy to give their opinion on setup 8)
You obviuosly got a big problem there,
regards
-
im thinking of dropping everything to a local computer store.
if another mobo will solve this problem, i guess im up for that. it's not worth my trobules right now.
-
i will do that, but 30 days are over since i got the parts.
sigh...
-
Hi Tomy
Request rma for both,
tell them you have had trouble from the start moan groan and grumble at them, :o
they have to cover you for the first 12 months anyway ;D
you live in the UK?
-
nope im in canada.
thanks for all the help. they have agreed to rma the products, ether cpu or mobo apparently, now i gotta figure out how to ship everything to them
THANK YOU!!
-
Hi Tomy,
I would be inclined to rma the mobo first, rebuild outside case and test it, with one stick of memory at a time,
Can't see the cpu giving up the ghost ???
Don't forget your mobo only supports 2 sticks of ram ::)
regards
-
haha yea.. it only supports 3 :D
ncix was nice enough to rma the ram, mobo, and cpu
so now let's see what's the problem and let's hope it's done once and for all and i wont be back on this forum :P
thanks for all the help anyway :)
appreciate it a lot
-
Hi, Tomy
Glad you got it sorted, did you think to ask if the would assemble and test it's all ok before sending it out to you 8)
Bet you did'ny ;D,
Best wishes anyway 8)
just gave you some Karma M8

update, just got it back this week, havent really tested it yet, but it seems to be running stable. so it was the stupid mobo that was causing me so much suffering
mobo got rma-ed
thanks to everyone who helped
