Memtest 86 - less errors is good?

Hi,
I recently RMA'd my ram after a Memtest run showed up 4,500 errors at 5% of the overall testing :)

I've run the new stuff through the same test at stock speeds (it runs at FSB1333 C9), and had no errors.
The memory is supposed to work on the whole XMP profile thing which means it will run at 1.8v, 1600fsb, C7.

I put that overclock back on (3.6g, FSB1600, C7, Command rate 2T - it won't boot at 1T), and ran memtest again and got 13 errors after about 2 full passes (Tests 2,4 & 7 are where failures occur)

So my question is this - is this acceptable? It's definitely better than the thousands of errors I had last time, but the RAM is supposed to be able to hack it. Does that kind of error rate spell trouble for everyday running or not? I'm getting about 18,100 on 3DM06,

So is this the best I'll get, and will it be fine? Or should I go get some good 1800mhz stuff and tighten it up from there?

Cheers,
Rob

Nope, I would still send it back stating that it got errors (less) after 2 tests. You don't buy new hardware with the expectation of faultiness, you should get what you pay for. Also, any error is a bad error.

Yeah send it back... Otherwise it'll always be at the back of your mind causing paranoia and insomnia..

NO errors are acceptable, any more than none at all is totally unacceptable.
is that the Corsair in your tag that we're talking about? at least it has a lifetime guarantee....

I'd try upping the volts a tad first. The ram my not necessarily be 'faulty', it might just need a bit of extra voltage to do the speed/timings stated.

Thanks guys - Yeah Corsair - 2nd set in a row dud.. I'm surprised.

Sicmic, The XMP profile recommended voltage is 1.8 over comparedto 1.5 I think from the standard timings- you think I should push over that?
I don't think a little extra will leave a mark but i definitely don't want to bugger the ability to send it back.

No don't push over it, but if it's not working at the specified V (1.8) then yeah, take it back.

It works at stock speed, you said. The fact it doesn't work when it's overclocked isn't reason to send it back under warranty.
