Left memtest86 running for 7hours and recieved 92 errors

hell yes, ANY errors on Memtest mean unstable ram.

If thats at stock its pretty much cause for an RMA.....

check each stick seperately in different motherboard slots, running stock settings.
 
I think so. Try each stick separately.

good advice..

If each stick shows errors then it's highly unlikely that both are faulty. It could be that they are not recieving the corrct voltages or the timings are incorrect. Check the manufacturers of the RAM for recommended BIOS settings. Then try again.

If one stick fails but the other doesn't then its certain to be faulty RAM.

Even better advice :)
 
fwiw: make sure you're pushing the right volts through vDimm. If you're set at 1.8v, DDR2, and running 4GB you're likely to end up with errors. Kick it up to 2.1v, for DDR2, or thereabouts.

Assuming, of course, you've done the 1 stick at a time test recommended above.

THANK YOU!!! I just happened to run Memtest as well today, and received a few errors. I was about to set myself to wake up tomorrow morning and go on a rant at Crucial, but bumping it up to 2.2v sorted it all out!!! YAY!

Incidentally, to the OP, try bumping the voltages up to the recommended volts before trying one stick at a time. If you have 2gb, for example, and take out 1gb, then obviously this will require less volts, and will work. It does not mean that the other stick is faulty, as it too may work alone when it receives the volts that it needs.
 
*sigh* Thanks for the advice everybody, I have 4gb of this stuff

It hasn't been overclocked or anything although my CPU has, the timings/speed etc are all stock speeds and it's set at 2.1v as it was even more unstable at 1.8v lol. It seems to be really hot to the touch as well, seems to be hotter than it should be at stock speeds to me.

Bah, can't be bothered to play around with RAM, I'll have a look at it tomorrow.
 
Here's a random screenshot of the settings for them on CPU-Z. Don't know why that would help. I'm tired I suppose I don't need to make sense.

Test the sticks indepandantly, i know its an ass.... i had to do the same last week with 4x1GB, but in the end i found the 2 busted sticks, and they are going off for RMA at some stage. You'll prob need a few hours, so it might be a weekend job, but the broken stuff should start producing errors fairly quickly.... run a few passes over them all anyway, otherwise you might miss something.

The screenshot tells us you are using the right settings (as long as the rest of the timings are on Auto or whatever), which is a good start. You really shouldnt need 2.1V with that ram though, the EVP is there for overclockers, not as a stock setting to make the stuff work properly.

If you NEED to use your comp and are worried about problems with corruption, try dropping the timings to something like 5-5-5-18 in the meanwhile, but testing that ram should be a priority..... its NOT good to have busted ram in a system..... I've borked my XP install with a bad RAM overclock before, it's much more dangerous that a slightly unstable CPU IMO.

Right well I tested each stick seperately for a short while. Left all the bios settings on Auto.

Stick 1: After 5minutes, 62 errors. I'd seen enough.
Stick 2: After 5minutes, 106 errors. I'd seen enough.
Stick 3. After 30minutes (1 pass), 0 errors.
Stick 4: After 30minutes (1 pass), 0 errors.

I think that I may put stick 3 and 4 in together next and leave it for a few hours.
 
Test them separately at 800mhz, 2.1v and 4-4-4-15. If the two dodgy sticks are still failing then it's RMA time.
 
Bah the first stick has been running for 20mins now on those settings without any errors. It's annoying me now I want to work out what's working and what isn't.
 
Bah I did a pass with each stick on those settings and didn't get a single error. Just shoved all 4 back in together and I've had 2 errors 18minutes into the first pass.
 
Which motherboard?

Raise the northbridge voltage by 0.1v to give it a boost for 4 sticks.
 
I looked in the BIOS and the Northbridge Voltage is set to AUTO and my choices are

AUTO
1.25V
1.40V
1.55V
1.70V

Should I change it? And which one to?


I think it is also definitely worth mentioning that ever so often (well quite often actually) when I've been fiddling with memory settings/running memtest etc when I turn on my PC I get no signal on the monitor or any response at all and the graphics card starts spinning at max speed. I normally just end up constantly restarting until it eventually decides to work (when it works I am greeted with an "Overclocking failed!" message.

Thanks for your help btw I really appreciate it I'd just be clueless and getting really really mad without your help haha.
 
Try 1.40v.

The no signal message is simply because the computer can't boot at whichever settings were entered last.
 
Ok will do I'll test that out now.

Yeah it just seems to be that it's overly sensitive about it for example it did it basically each time I changed module after doing memtest, and when I put them all in together even though they require the same settings in the BIOS.
