Hello,
My supertalent ram is only running @ 1600 Mhz. It's rated for 2000. Latest bios. 1055T CPU & gigabyte 890GPA-UD3h rev 2.1 motherboard. Any thoughts, please?
Thanks.

You need to manually set the frequency to 2000Mhz in the BIOS, or overclock the CPU, TBH you wont notice a difference between 1600 and 2000

Have you increased the voltage settings for it? Or like Sniper said, you might need to also increase the cpu with it.

Hey. Thanks for the input. I am at 1.65v for the ram. But that is manufacturer spec. On the motherboard, the setting just above 1.65v (1.66v or something) is in the red zone. I shouldn't have to overclock to get manufacturers specs to work though, right?

Do you guys go by what it states after the bios posts (BEEP) and says ddr3 1600 unganged or do you judge the speed through some other method?

Thanks!

No, that's not right. The manufacturer specs the RAM based on what it's capable of. It's up to you to get it up to that speed. Depending on the architecture (and how high you're trying to go) this is as simple as changing one setting in BIOS or as complicated as changing many settings, OCing your CPU, and adding additional heatsinks.

As was mentioned, there's very little performance difference in most applications for each incremental step-up in RAM. There would be a lot less headaches if buyers understood their CPU/motherboards max RAM frequency and the challenges involved in upping that before buying RAM. And money that could be spent on improving real system bottle necks. But we've all done it, buy first and ask how the heck to get it working later!

Hi. Thanks, but what I meant was the manufacturer specifications on the motherboard, cpu and memory all state that they support 2000 mhz ram withOUT overclocking. That is why I am so confused at the advice that I must overclock. Thanks.

The memory manufacturer can't say that, it doesn't know what machine you're putting it into. The CPUs don't typically specify and motherboards, well it often depends what CPU you're putting it into.

I agree, they don't always say you have to OC to achieve certain speeds and so by omitting that language they allow people to think it's easy and doesn't require an OC.

However, I checked the link you provided to the motherboard. It does say "Delivering native support for DDR3 memory up to 2000MHz" as you mentioned. However on the Specs page it also says "Support for DDR3 2000(OC)" - so to get to 2000 MHz you have to OC the RAM and/or the CPU.

Interesting, the manual states "DDR3 1866(O.C.)/1333/1066 MHz"

Also, if you're RAM is installed in DDR3_1 & DDR3_3 -> try -> DDR3_2 & DDR3_4 ; the reason I mention that is I've seen some Dual Channel GA manuals indicting RAM > 1800 MHz use the 2 | 4 slots {second set}.

If 2000 MHz fails then 'try' 1866.

Good Luck!

Thanks guys. Thanks everybody. I really appreciate you catching the things that I apparently missed like OC and the other two slots and etc... Dang fine print! :( 

Oh well, I guess I'm just stuck at 1600 until I can figure out otherwise...

Could be worse places to be stuck! Since it's rated to run faster, you might be able to run it slower with tighter timings. So while at 1600 you could give timings of 7-7-7-20 a try. Just be sure to keep the V set and then test for stability.

Or you could just say it's running good enough as is and not spend the time trying to squeeze a little more out of the system. Tom's has done write-ups on the Phenom II, and Intel's 1366 and 1156 platforms. In all cases, small steps up in frequency or timing resulted in very little real world differences. Here's their Phenom article if you're interested: http://www.tomshardware.com/reviews/phenom-ii-ddr3,2319...

JDEC standards only go up to 1333 for DDR3 ram, anything over that is "overclocking" Your motherboard doesn't support running at 2000.

You noticed my prior post, also unless you are OC the CPU +30~+40%+ is about the only justification to run the RAM > 1600 MHz.
