supertalent ddr3 pc3-12800 4*1g problem

[ivan__jedi]

recently i upgraded my supertalent ddr3 pc3-12800 memory from 2g to 4g.

then the system could not start up at all unless dimm voltage at 2 volt @ 1600mhz !!!!

must know that the supertalent ddr3 pc3-12800's default voltage is 1.8v and it was running perfectly at default profile when there was only 2g of this memory

anybody has any idea???

thanks a lot

basic system set up:

core2 e8400
maximus extreme
supertalent ddr3 pc3-12800 4*1g
vista business 64bit

loosen up the timings and pull back on that voltage. By the look of your processor you should adjust the skew if there is the option. That's FAST ram for the proc.

Perhaps a little bit more NB voltage?

thanks for the advices

i am a noob totally tried dimm 1.90v 8-8-8-24 didn't work 1.96 allowed me into the system but died when i tried to run cpuz

could u guys give me some advices on the cas config??? 9-9-9-something???

nb @ 1.49v


i dont understand since its default voltage it should be no problem shouldnt it?????


problem with the mb???

Your problem doesn't sound like voltage will help. You're already pushing it beyond the stock volts for stock speeds. Either loosen the timings and mess with the cpu/nb skew, or underclock them to 10666 and run memtest to see if you have bad sticks.

As an after thought you might want to try using only one module, then two, then three, and finally-- you guessed it-- four sticks!

:EDIT: We're all noobs (but some have greater instincts than others) when it comes to new hardware. You have to really sit there and fiddle with numbers or search the interwebz/manufacturer's forums for like situations. For instance I went to OCZ forums to see how to overclock their ram on my mobo-- a lot of people have had problems doing it so there was a lot of useful information. If that wasn't there I'd still be in my bios, fiddling.

the sticks are definitely fine. i tried them seperatly ran memtests they worked ok

i also, as binge suggested, messed with the ratio and overclocked the system didn't work at all

so far no progress sigh

I guess... incompatability with the motherboard then? Sorry I'm fresh out of bios options I know of that would help :shadedshu

Try 9-9-9-26 timings.

 

[Binge]

good idea. My timings are around that.

that ram needs to be set manually to a tRFC of 72.

1800mhz @ 7-7-6-18 with a tRFC of 72 at 2.04v works very well with those sticks. you can run the same settings at 1600mhz with 1.84v

 

[ivan__jedi]

thank for ur tips fitseries3 however it didnt work very well

i still need some 1.9 volt (@ 9-9-9-26)to just get into the system and then die

i start to seriously wonder if it is the problem with the motherboard??

 

[ivan__jedi]

According to some online material i have come accross. This problem is very likely due to the motherboard design of ASUS. Its x38 motherboards seem have fairly poor overclocking capability if all four dimm sockets are used. In contrast, Gigabyte x38 series dont have this porblem.

I think this might just be the answer.
