umh i am testing a kit of g.skill with d9jnm.
i found i can bench @ 960 7-7-7-21 with 2,1v and fully stable 960 8-8-8-20 with 1,9v!!
but the problem is i cannot go more than 970 at any cas... i tryed 7 , 8 and cannot go higher 970 with any voltage also.
i have a R.E. there is something i can do to try ?
vNB i tryed up to 1,65v.
I would hazard a guess that you are at the limit of the ram, it is not renowned for overclocking at all. You should be able to do ~900 MHz at CAS 5, but more than that is not likely. Increasing CL to 6, 7 and 8 when at ~960 is just going to lose you performance compared to ~900 CL 5.
I'd invest in some more ram that overclocks better, DDR2 is quite cheap these days compared to back in the day.
LOL i was talking about DDR3 ^_^
try adjust skews in memory timings page.
use this next timeQuote:

ur thinking of hnl/hnm
the jnm is the same chip as the jnl, so u should be good for a little more what board do u have, if ur x48 then 1.65V on the NB is low for that kind of benching
before adjusting skew try to raise NB DDRVref, DDR3 ChannelA Vref, DDR3 ChannelB Vref one or two steps higher
rampage extreme motherboard!!
umh i dont have too much confidence with skew... someone can give me an example to adjust to try for my configuration ? ^_^
oh my IC's there's write D9JNL :)
i tryed up to 1,75vNB @ liquid cooling custom (not wb of rampage) but nothing
i will try with DDR ref but with csx diablo i dont need to push em.
what about skew?

Not on the same board, but I can say each channel should get different skew.
what are u talking about ??
i have rampage extreme, how can i set dram skews to try if its better ?? delay 150ps or adavance xxx ps ?? or ??
like I said, I have a different board.
skew on that board is easy to test, as you adjust either way, it will not boot, obviously midpoint is most stable.
channel A and B must be the same Skew or different?
possibly different, there may already be some offset between the two already in asus bios, I am not sure.
if someone with R.E. can give me some help with skew would be great ^_^
pll : 1.55
Vtt: 1.35
strap to nb : 400
Dram :1800
7-6-5-18 1T
Vnb:1.54
Vcore : ??
Vdimm: 2.08 u can try 2.20max :yepp:
use the white slots and boot @ 600 X 6
i have ur same rams and can boot @ 630 X 6 without problem cpu@ Nirvana Nb stock aircooling with 80mm fan and 120mm for rams
620 Am3 stable all air ;)
Your D9JNM like 7-6-5-X ? Interesting.. But 2,2v no healthy for JNM..Quote:

with 7-7-7-21 and 2.10 ram got 2ghz :) 8m stableQuote:
