Crucial Tenth Anniversary Timings?

[BoysBoysBoys]

What are the default timings for the Crucial Tenth Anniversary TY2KIT12864AA663?
What should I set my subtimings to?

Right now my motherboard reports this in the BIOS:
CAS Latency Time: 5
DRAM RAS# to CAS# Delay: 3
DRAM RAS# Precharge: 3
Precharge delay (tRAS): 15
ACT to ACT Delay (tRRD): 3
Rank Write to READ Delay: 3
Write To Precharge Delay: 5
Refresh to ACT Delay: 35
Read to Precharge Delay: 3

System Specs:
Gigabyte GA-965P-DS3
Core2Duo E6300
Crucial Tenth Anniversary TY2KIT12864AA663

HERE IS MY MEMSET

Thankyou for your help!

Are you overclocking, ie: Memory running at >533Mhz? If not, you can set it to 3-3-3-8 for the first four. The higher you push the memory the looser (higher) you'll need the timings. Mine runs at 920Mhz at 5-5-5-15

5-5-5-12 @ 460 or ddr2-920 is still a bit loose.

i'm sure you can tighten it up a bit to 4-4-4-10.

i have mine at 4-4-4-10 @ 475 or ddr2-950 with 2.25 volts.

but if you're limited by voltage then i'd understand why you'd have to use 5-5-5

BAH!! Turns out I've been running it at 2.1V but they're rated for 2.2V! D'oh, I've been cheating myself out of extra headroom because I didn't want to go past "stock" yet.

LOL.

These are supposed to be handpicked D9's in the 10th anniversary so they are good stuff.

Give it a little more juice and i'm sure you'll see these things fly!

But what should I set my subtimings to? When I press ctrl+f1 in the bios and bring up the advanced options I can either select auto for everything which brings it down to 5-3-3-15 and sets my subtimings properly or I can adjust it to 3-3-3-12 and set the subtimings to auto, the only subtiming I cant set to auto is the tRFC (Refresh Cycle Time) which defaults at 0 if I take "auto all" off

Yeah, you should definitely be able to tighten the timings. Even my ultra-budget Kingmax (supposedly Elpida chips) do 920Mhz at 4-4-4-12 on 2.1-2.15V, so I'd expect better from Crucial high quality sticks.

I have been using this memory with an AM2 system, but I have an E6600/Gigabyte DS3 combo coming in tomorrow. Should be very interesting!

Set it to 3-3-3-12 and the rest to auto. Tweaking it anymore than that could be a PITA and won't yield any significant performance increases.

i'm still curious to see if you're overclocking or not.

if you're running stock, 3-3-3-12 with the rest auto as the above poster said should be fine.

and i agree that tweaking the subtimings is mainly for those trying to squeeze every last bit of performance from their system for benching or testing... the average oc-er/ gamer / everyday use system won't notice the difference with these timings.
