'Asus A8N32-SLi' and 'G.Skill HZ PC4000' not working together?

[G.O.A.T]

I have bought 2GB of this G. SKill HZ 4000 to replace the value RAM in my PC. The first batch arrived faulty so I RMA'ed it to G. Skill and got the supposed working replacement today. However I am really struggling to get the memory working.

Putting only one stick in seems to work fine at 250 mhz and pretty much what ever setting I choose but when I try both sticks at once in whatever configuration I get random crashes or it woun't POST. I am forced to run at 200mhz with 2.8 volts, cas of 3 and a t of 2 just to get the things running. In addition to this I can't put both sticks on the same memory bank as dual channel means I can't even reach windows.

Is anyone else having problems with this memory or motherboard combo? In it's current stable configuration my value RAM works faster! I don't to RMA this for a second time perhaps I could send this back to OCUK and swap it for some nice Corsair?

I would be grateful if anyone has any ideas on what could be causing this!

when you put them in dual channel mode.. i.e. dual channel slots

are you sure it isnt resorting to dual channel 250mhz? i had the same problem, but i had to knock it down to dual channel 200mhz then clock up for it to be stable at 3-4-4-8 or 3-3-3-7

Yes if I put the RAM in banks 1 and 2 it barely gets to windows but in banks 1 and 3 I can just about get it stable at 200mhz with 1.8 volts.

hmm....

i think i had a similar problem before... in the end i got a new mobo.. this asus

i had a pure innovation and the only way i could get the computer stable with any ram was setting the ram at 166mhz.

i think you should try some different memory if you can... a different make. contact asus, gskill tell them your problem, gskill were pretty helpful to me last time, they give me various options to try, and eventually suggested it was the mobo that was the problem... maybe they just wanted rid of me

i can understand how you feel... it took me 4weeks to get it sorted

PS: as one of your sticks runs fine at 250mhz then it could be just the other stick is faulty... explain this to gskill

Sorry when I meant one stick I mean either of them work fine individually, it's only when in use both together that I have these problems. I also have two sticks of Corsair and one stick of Geil (all 512mb) that have worked without issue at 200mhz in any combination of RAM banks. I'm upgrading the BIOS to the lastest version and will let you know what happens....

ok right I have updated to the lastest motherboard BIOS 1103. This has allowed me to run the memory together in banks 1 and 2 and reduce to voltage to the default 2.6v. However if I try to run at anything faster than 216mhz even with 2.8 volts I get the usual lockups. (far from the 250mhz I was expecting.)

edit : well I've managed to get it stable at 233 with slightly slacker memory timings (250 still a no go,) seems to be too much of a pain in the arse to get this stuff to run high fsb so i might just set it at 200 and see if i can get some lower latencies.

using the settings mad recommended now work at 250mhz.

CAS latency (CL) = 3.0
TRAS = 8
TRP =4
TRCD =4
TRRD = 2
TRC = 13
TRFC = 24
TRWT = 4
