strange finding

[nefariouscaine]

I have my nifty kit of Crucial Anniversary series DDR2 -- spec'd to run at DDRw-667 at CAS 3-3-3-8

good stuff IMO

I've *always* OC'd it to that with a few exceptions when I booted stock

well I'm not sure if I'm an idiot and fried the ram but I was having some issues booting windows after installing some beta Nvidia drivers (a whole nother issue) so I tried to go stock but gave up on windows as its too picky about errors and went Ubuntu instead (dual boot)

had some problems getting in at first and thought just for sheits I'd run memtest

what do you know in 5 seconds I get 30 errors -- this is all mobo default settings

ok cool I think -- I've fried my memory even though I have 2 fans on it

but then I proceed to set the "passed" oc settings of 2.2v (closest I have is 2.178) at 3-3-3-8 DDR2-667

and by george it passes with no errors -- to say the least I'm confused

I'd have thought *all* memory would be fine at SPD settings at 1.8v -- but then again this is "OC" memory

any thoughts on this would be great

-- I'm off to try to uninstall those ah heck beta drivers and plan on my new PSU I'm going to buy

The D9GMH IC on that memory is hand picked and speced to run at 2.2v With less, it will error because it needs it in order to run the low timings. If you check the SPD settings of this memory it actually tries to run cas3 at 667. Something it cannot do with less than the proper voltage.

I had checked the SPD and it actually says CAS5 -- but I had thought about it and I remember a fair number of DDR2 that was put out having issues with Intel chipsets (ie p965) due to them needing 2.0v to boot at DDR2-800 at CAS5

This stuff posts just fine but errors out at 1.8v like I said -- I'm going to do more testing later on today but I'm not so concerned as its running at advertised settings fine
