RAM in last slot keeps failing

kskwerl · 06-29-2009, 09:19 AM

Hey everyone, hope you guys can help. Here's whats going on..

I have a Foxconn ad7a-s mobo that supports up to 8gb on ddr2 1066 ram, originally when I built the computer everything worked fine until a month or two later when I went to turn on my computer and the computer would run but I wouldn't get any display on my monitors. So after messing around trying to see what the problem was I took out each stick of RAM and it was the RAM in the last slot that apparently was causing the problem. Ok..so whatever, I just thought bad RAM, no biggie, I got another stick of the same exact RAM Kingston HyperX 2gb ddr2 1066, everything has been fine for quite a while. Now last night I went to restart my computer and when I restarted I got no display so the first thing I checked was to RAM in the last slot and sure enough that's what it was.

Any idea to why this is happening?
I am running Vista Ultimate 64-bit, I also read somewhere that it may be your power supply? I have a pretty good 650w brand new PSU.

Any help is greatly appreciated!

what are you running
video card
cpu
m/board
ram
power supply
brand
wattage

check the listings in the bios for voltages and temperatures and post them

check the voltage range for your ram and see if you have scope to lift it

do you have fox one installed? if so check that voltage is 2.2V
check the frequency too it may be less than 1066.

note: KHX8500D2 SPD is programmed to JEDEC standard latency 800Mhz timing of 5-5-5-15 at 1.8V

Thanks man, I have Fox One installed.

DRAM says 1.74

And DRAM Freq. is 800

lol as you said. I'm not to sure what to do about the SPD in terms of "Auto" "Limit" or "Manuel". The manuel says that 1066mhz will only appear in AM2+ CPU's. I have a Phenom 9850 Black Edition. Is this AM2+ or AM2?

AM2+, but only with 1 stick per channel so if you fill the ram slots that's 2 sticks per channel and it runs at 800.

Thanks, good lookin out

Kingston HyperX is known to have problems. Are you filling all of the RAM slots on the Mobo? That can also cause Voltage issues.

Is it really? I thought Kingston was a good brand :(

And yes I am filling all the slots on the mobo, it's max ram capacity for 64-bit is 8gb, so I have 4 sticks of 2gb HyperX.

Another really weird thing is when I go into the BIOS and try to manually set the freq. of the RAM when I set it to 533 and then try to boot my computer it says "Boot Image is Corrupt" *** is that all about.
But check this out, when I changed the multiplier for the cpu to anything above 12.5 I get in the 1000s for the freq. for the RAM. I don't even know why that is happening.

Ok, so the new stick of Kingston HyperX 1066 2GB came today from UPS, I plugged in the new stick and now the Foxconn One ultility is reading a frequency of 667! lol what is going on!?

**wrench97** · 07-02-2009, 05:22 PM

Is it the right stick?

Yes, very confusing..

Stu_computer · 07-02-2009, 11:02 PM

set memory to manual
set timing to 5-5-5-15
fsb freq to 533
using all slots bump up the nb voltage by 0.6V (two steps).
