a bad memory slot???

[tornadog]

Just when I thought my upgrade build was complete... last night I had to reboot my pc after making some software changes. boots up and shows 2040 ram in the bios. cpuz reports 2 dimms in slots 1 and 2. The dimms were in slots A1 and B1 on the board. After testing out each dimm in each slot, it seems like slot b1 has gone bad(dont know how). So I put 1 stick in slot C1 and it now shows 4088 ram in the bios.

my patriot memory is not on the QVL list of the sabertooth mobo. Could that be the reason for this issue? I cant believe a slot would stop working within 1 week of use.

I always keep a few sticks of really slow cheap ram (single sided if poss) that boots at default DDR3 voltage and has no fancy alternate spd profiles just for testing slots. If it wont boot with one stick loaded in the slot in question, then its bad.

Not working out of box is very possible, but after a week suggests something else.

You could try upping various ram related voltages a tad, also a warm boot - immediately reboot after getting to O/S screen load

Might also want to absolutely make sure ram is down in slot 100%

FWIW mobo/PSU today have a trickle voltage even when PC off
I know its a pain in the ass, but if you really want to protect your expensive ram you should turn off PSU with rocker switch and hold down "power" button for count of ten to allow discharge before removing/inserting

Edited: Oops. Didnt realize "sabertooth" is tri slotted,

many assume that if the system turns on, the RAM will work just fine. but guaranteed longevity is your risk of both the motherboard and the RAM sticks themselves, reason why the qvc list exists.

if I were you, I wouldn't breath too hard, as long as it reads 4gigs and the slots working with it are stable. "run it 'till it dies", that's my motto, lol

of course, this kind of sh!t may be so unpredictable, that if your set is not on the qualified-list, and say there is a BIOS upgrade, don't expect your RAM set to work after that. but this is just common sense speculation that any pc builder should know, nothing is perfect.

say the ram is perfectly fine with the mobo, maybe the mobo is crappy, and if there is one dud, hopefully nothing else happens, but if something else gets trashed, get the warranty ready.

manual first, get the slots and timings to default as to what is acceptable for standard set combinations. run a burn-in test on the defaults, then run a burn-in on the new tweaks.

like the other guy said, put another stick of different brand into the slot(s), and see what happens.

p.s. don't make the mistake of using gaming ram tweaks with cheap ram on reboot swaps, might force perm. dmg.

well I have been running it on slots a1 and c1 and it seems to be stable. I have run other tests, been prime testing my cpu. I guess I will keep it like it is for now. Anything else goes , it may be time for rma.

that fvcken sucks. mobo perfectionism, that's all an enthusiast wants, for everything to work perfectly, chipset wise.

of all problems, it should be the OS, not the mofo mobo. the rate of failure mathematics, in our world is too real to forget.
