Unable to run 2000Mhz on ASUS S2E 790i Ultra board

[crossover24]

Hi,

 

I have just recently purchased my 4x1GB Corsair Dominator SLi-Ready DDR3-2000 (PC3-16000) and I cannot enable the SLi-Ready Memory feature of the board and likewise run it at 2000Mhz successfully. I can only stably run it at 1850mhz, farther than that, I cannot boot my system up, had to reset CMOS. :bigeyes:

 

I have tried every setting on the BIOS of the ASUS S2E but to no avail. My system currently runs stable at QX9770 4.2Ghz and memory of 1800Mhz on the rated 9-9-9-24 2T timings. SLi-Ready is disabled which is crap as I tried to lower even up to 1333Mhz to even just enable the SLi-Ready feature of the RAM but when booting, keeps beeping and wont boot, CMOS reset again needed. Sigh....:sigh!: hope an expert in this forum or the manufacturer engineer can shed light to this as according to the Tech sheet of the ram, it was rated and tested to run at DDR3-2000Mhz on 9-9-9-24 2T on a compatible 790i board. Where is the compatibility here? :mad:

 

Please help me not realize I made a mistake of purchasing and wasting my money on a Corsair DDR3-2000Mhz instead of a Corsair DDR3-1800mhz ram. :[pouts:

You will not be able to run the tested settings with more then one set installed DDR1600 or DDR1333 would be suggested.

thanks for the reply, what do you mean with more than one set installed? You mean it wont run with 4GB installed? what if only 2GB? Or you mean it will run at 2000Mhz but I should have only 1 stick of it installed? Please clarify.

 

If it wont run at 2000Mhz, what's the purpose of selling a 2000Mhz rated Ram if it cannot run at it's rated speed on any board or on either a 2Gb or 4GB set-up?

I saw your link to the review of the DDR3-1600Mhz SLi-ready XMS rams and it was able to overclock to 2000Mhz. I noticed that the reviewer was able to Enable the SLi-ready EPP profiles of the RAM, I cant see any reason why my DDR3-2000Mhz should run un-overclocked at it's rated speed and unable to enable the SLi-Ready EPP Profiles on an Nforce mobo that accepts SLI-ready memory? 2000Mhz should be it's stock speed, and i'm running it underclocked!

 

Then does that mean that Ican only currently run it at a stable underclocked 1800Mhz? Currently, Im running it at 1800Mhz and CPU QX9770 at 4.33GHz (10.5 x 1650) on my ASUS S2E 790i Ultra board.

 

Can any board run this at its "stock" speed?

They are tested / rated / guaranteed as they are sold. In otherwords, ONE pair is guaranteed at the advertised settings. Due to limitations outside of Corsair's hands (e.g. the limitations of most memory controllers), not to mention that they're not tested / rated / guaranteed / sold as a 4 pack at those speeds, no one can guarantee that you'll be able to run all 4 @ those speeds.

i see, ok so you mean this should work on 2 identical sticks as it came as a set of 2x1GB? Lemme try that and see what happens. I'll keep you posted.

 

 

Thanks...

BTW, you bought 2 pairs of the TW3X2G2000C9DFNV, correct?

 

Any reason why you didn't get the TW3X4G2000C9DF so you would have a 4 GB set @ the speed / timings you wanted?

YEs, 2 pairs of TW3X2G2000C9DFNV. I chose it becuase of the SLi-readiness and to use it on my SLi-ready capable nvidia chipset mobo. The

TW3X4G2000C9DF dont have that. And also, no information was available that only 2 GB of ram or sticks can run the rated speed. But there should be no reason not to run it on 4 sticks of 1GB as other Corsair RAMS dont have an isue on this.

I have not seen many MB's able to run these modules with one set let alone with 4 modules. And with 4 modules DDR1333 or DDR1600 would be suggested depending on the CPU FSB.
