G.Skill 2133/2400 for the FM2A88X Extreme6+ ???

[wardog]

The Bolton D4 A88X chipsets aren't in G.Skill's Configurator yet so I'm hoping to have better luck asking here.

MB: ASRock FM2A88X Extreme6+ (BIOS 1.30, release)
CPU: A10-6800K

I'm looking for known working recommendations on 2133/2400, both 2x4GB and 2x8GB kits.


TIA,
wardog

The last gen ASRock FM2 models had serious issues with both faster memory. The official support for memory overclocking was even removed from some/most of the FM2 R2.0 models. Personally i had very good success with ASUS F2A85-V Pro and Gigabyte F2A85X-UP4 and DDR3-2400 G.SKILL TridentX Series memory kits ( http://www.gskill.us/forum/showpost....60&postcount=7 ).

So if you run into stability problems at DDR3-2400, maybe think about getting another mainboard instead of returning the memory =)

I was thinking I could underclock/undervolt 2400 for some decent timings.

The 6800K is spec'd to run 2133 out of the box.

I think he was saying the board has issues with 2400. But yes the 2400 mhz memory is better memory so even if you have to underclock it, it should perform better than 2133 or 1866 memory.

You could do that, but you could also just buy a DDR3-2133 CL9 kit like F3-2133C9D-16GTX or F3-2133C9D-16GXH from the start. My F3-2400C9D-8GTXD and F3-2400C9Q-16GTXD are able to run DDR3-2133 at 8-10-9-24 / 8-9-9-20 and DDR3-2400 9-11-10-27 well below 1.65V (y.m.m.v.), if thats what you're looking for.

I did not say that. I just said, that the FM2 models from asrock have had problems with higher memory speeds (e.g. FM2A85X Extreme4/Extreme6/ITX). So if he runs into problems with DDR3-2133+ and his FM2A88X Extreme6+, then it is probably not the memory that is causing the issues.

Yea, your F3-2400C9D-8GTXD is on my short list.

emissary, how much below 1.65v might I expect at 2133? Taking into acct each boards reporting and supply issue(s)? I'd like to stay in the 1.5v-1.75v range if you think that's possible at 2133 with this ASRock A88X board.

I did not say that. I just said, that the FM2 models from asrock have had problems with higher memory speeds (e.g. FM2A85X Extreme4/Extreme6/ITX). So if he runs into problems with DDR3-2133+ and his FM2A88X Extreme6+, then it is probably not the memory that is causing the issues.

I 'heard' you proper like when you posted the aforementioned concerning the ASRock FM2(not FM2+) boards. That's why I waited for the FM2+ boards to come out. Hopefully the FM2+ board I have now doesn't suffer too bad.

It's one of my servers so I'm not awful concerned with 2400 speed, yet I'd still like to find some 2133 to run it with. Preferably something 1.5v'ish.

Currently has Samsung MV-3V4G3D/US in it but I don't need to/want to/nor care to overvolt on a server. Otherwise these green sammy wondersticks do 2133 no problem.

[wardog]

Oh!

emissary, might I get away w/o using the incl. fans on those F3-2400C9D-8GTXD at 2133?

[supahos]

As long as your case is well ventilated the fans aren't required unless you're overclocking them. And since you're considering underclocking them it should be fine. As for how low you can go on voltage at 2133 you "should" be able to do slightly less volts than the 2133 kit that is the same as the 2400 kit should have better chips inside.

I never used the supplied fan, even at DDR3-2666+ (they get plenty of airflow from my cpu-cooler).

Depends on the timings used. For CL8 you will probably need around 1.6V, but at CL9 you are in 1.4-1.5V territory.

Did you actually try these on your Extreme6+? We had tons of problems with these on lots of FM2 mainboards. The ASRock ones sometimes did not even boot @ DDR3-1866 with them.

Thanks for the info. Greatly appreciated.

Yea, the sammys are running in it now, albeit w/o any attempts at OC'ing 'em. Booted right up at 1600, whether two or four sticks were used. BIOS resets in between 2 and 4 sticks, but uneventful nonetheless. My 3770K loved 'em like sugar.

NewEgg has an upcoming ShellShocker on F3-12800CL9D-8GBSR kits that I might just settle on. Cl9@1600 1.5v. Waiting to see what they price them as as I might just get a couple of kits and get 16GB instead.

[supahos]

Lol yeah I was watching the same sale I really don't need any memory, but I just might buy some for a rainy day if they are cheap enough

[Dweezil]

I have a extreme6+ with a 760K and cannot for the life of me get my Trident X 2400 to work. Anyone have any success yet? My proc natively supports 2133, so I may shoot for that first, but need some timings to manually input into the bios... anyone want to chime in, or should I start a new thread? Thanks

[emissary42]

Which of the TridentX DDR3-2400 kits exactly (CL9, CL10, 2x4GB, 4x4GB, 2x8GB, 4x8GB)?

Start around 9-11-10-27 2T 1.65-1.60V

I have the F3-2400C10D-16GTX , 2x8GB sticks.

You may need to raise CPU/NB Voltage to boost the memory controller to be stable for DDR3-2400.
