Windows 7: memtest86+ v4.10

I can't boot to memtest from USB with a stick in a secondary slot. Like it must be either a1 or b1. Is that normal? If I know I have all good sticks of ram I can just run memtest with a1 and a2 then if that fails I know a2 is bad? Same with b slots...?

good sticks in slots a1 and a2 pass, then good sticks in slot b1 and b2 pass

then when i put all four of them in, errors

im getting frustrated with this.

edit: going to run known good pair in each combination of slots. then run other pair in same configurations. i think i may just have more bad ram... wtf

What this sounds like is that when all 4 slots are populated the power to all drops, but when the system is only powering 2 sticks it's stable. Insufficient power to the RAM will cause the errors. This can be caused by a faulty power supply or a faulty motherboard, but sometimes it is just a glitch in the power to the modules.

You can use CPU-Z to look at your voltages and compare them to the motherboard's spec.
A test to try is to go into the BIOS and up the voltage to the RAM slightly. If the RAM Bus is running at 1.65v now you tweak it up to 1.70v and test.

I should have asked this before, but are you running the system with all the BIOS defaults for Main system components, CPU, and RAM? Have you made any previous changes using the AI Tweaker?

all bios are at default (except AHCI controller) and updated to current rev

i ran the two good sticks i had last night in a1/a2 they passed 11 passes no errors. i have them in b1/b2 now and when i get home im assuming they will pass without errors.

then ill run the other pair in a1/a2 and b1/b2 to see what happens... if the other pair fails where the good pair did not that would indicate bad sticks right?

just got home... same sticks that passed 11 passes in a1/a2 passed 12 in b1/b2... no errors.

going to start with the other two sticks in the same two configurations to see if it is indeed bad ram sticks again

Not liking the voltage idea, huh?

If both pairs of modules passed in slots A1-2 and in B1-2 then I think you can assume the modules are good and you will need to look at other possible causes.

yep......... errors with the other two sticks

man this is kind of stupid.


edit: saw the reply... i ran the two known good sticks in both pairs of slots.. to ensure that the slots themselves were good. when i got home today i put the new sticks that came from the RMA in, and they showed errors on the first pass - with only two sticks installed... that kind of debunks the voltage issue

Yep. I agree.
That's the hard part about diagnosing systems across the ether. It's sometimes hard to get the picture of what you have done/are doing straight in my head!

It sounds like you got a handle on it now. It's still pretty bad that you got an RMA replacement that was also bad. I'd be rippin' !!

I've gotten recent BSOD's, first i took my computer to the store and my graphics card was messed up. That was some months ago and i got a new graphics card. The BSOD's still occured though and last night I ran memtest86 for 4 passes and? it had 40 errors. Is it pretty much safe to assume that...
