hem I was playing around with my memory timings and I got this:

i think the tRAS must be a world record or something has anybody seen anything like that tRAS on ddr2 memory before?
Thanks,
Jules
EDIT: and it passed a ram stability test with nearly no errors.

A rabid goat with alzheimer's could probably pass the RAM test in most BIOSs....
If you nearly pass a test that's mostly designed to check if the RAM is plugged in correctly, then it's seriously faulty for normal use.

i assumed that by 'ram stability test' he was referring to something substantially more than the BIOS self-test -- most overclockers have a set of tools to use for testing this much more comprehensively -- some of these tools will actually give the specific latency from each part of each transaction, in different ways, and puts extreme stress on the parts -- so that even normal parts, at stock clocks, will eventually fail -- or maybe something simpler like prime95 -- which puts a lot of stress on the parts, but doesnt provide quiet as much benchmarking detail
the BIOS self-check, doesnt qualify for the term 'stability test' and therefore, probably wasnt what was used...

To test it i use for instance of memtest (reached a core temp of 126C though that probably isn't reliable (Intel says that over 85C the core temp readings are no longer reliable)) and the ram gets insanly hot even with the reaper heat sinks. eventually under this kind of stress most parts fail even at stock speed so nearly passing with no errors is pretty much insane.
But has anybody actually seen any timings this low before?
Thanks,
