Last night, I decided to push my 8GB Crucial DDR3 1333 CAS9 1.5v to its limit.
My settings were 8-8-8-21 1.6v@ 1850mhz

I bought this ram for $40 shipped from newegg back in the early summer (8GB = $80)

Ran it for 2hrs without any hiccups. I really wanted to try out 2000mhz but I don't think my asus p6t is going to like it. Mosef already runs hot as is.

Which chips do this modules use?

There is a thread over at XS where Crucial DDR3 1333 with D9KPT ICs have clocked quite nicely and seem to scale really well with voltage. The thread started around mid-summer so I was curious as to whether your sticks were using the same ICs.

Thanks for the info!
I'll check into tonight. I was comtemplating whether to get another 2x2GB Crucial or 6x2GB Gskill 1600 and sell off the crucial...but didn't feel like getting a different batch of Crucial mixing with the old ones.
I'll keep you updated.

Just checked all 4 modules, and they are 09-KPT
Is it safe to increase the voltage above 1.64?
Currently running 1850@ 8-8-8-21

Over at XS, in that thread that I've linked, they've pumped way more thru them, but it wasn't for 24/7 use. As a general rule Micron chips tend to hold up well under higher voltages and I haven't seen any posts complaining about dead ram so I'm pretty sure that you easily go to 1.85v-1.90v without issues, as far as the ram.

This next linked thread is some testing done by eva2000 on some OCZ DDR3-1333 "Animal", which turns out, also uses these same D9KPT chips (see post #47 for pic). George provides lots of screenshots, running them at different timings and voltages...again, you'll see voltage amounts in excess of 1.65v.

If VTT is within 0.5v of vDIMM, it's supposed to be relatively "safe" to run more than 1.65v...
