pushing 8000ul beyond 2.4v

[proth]

So I've been running this 8000ul @ 2.4v 1000MHz, 4,3,3,8 for a few weeks now and just Vdimm modded my P5WD2-e. Jacked it up to 2.5, 2.55, 2.6, absolutely no increase in performance, can't even trim off a clock anywhere.

I thought these D9 fatbodys could clock 4,2,2 @ 1000. Any ideas. Need to trim off 1.2s off my SP32m. Want to avoid removing the spreader to check which rams are installed.

corsair 8000UL ? They are D9 AFAIK

Try going 1:1 and see if that helps ( if you can go 1:1).
Most pairs should be able to go a bit above 1000+ with 4.3.2.4 or 800+ for 3.2.2.4, but to be 32M stable might be a tougher cookie to chew on for some sets.
Make sure to have type of active cooling for the ram. 2.4V sounds a bit low - 2.55V has been sweetspot for me on many D9s - but there are always up and down variations. On the other hand I've never ran 2.4V actual for 24/7 and for weeks - maybe they regressed? Would surprise me. Actually doubt it.

2.4v, holy crap. Has anyone killed D9 sticks via voltage?

Thanks Mike. I'm @ 1066 4,3,3,8 and 880 3,2,2,6 on 2.2-2.4v.... Was just looking for more. Ram isn't even warm and sp32m stable @ 1066, 4,3,3,8, around 23m SP32m. From what I see, these are a hot set so maybe I'll just keep running them at 2.4, why ruin a good thing.

I have, but I work for Corsair.

I have seen the Microns die as low as 2.4V and as high as 2.9, but that 2.9 was an accident...

As far as going 4-3-3 at 1000, the tRCD seems to be the limiting factor in my experience. 4-3-2 should work almost identical to 4-3-3, and the tRAS can be anything, I've never seen it make a big difference.
