How fast ram AMD FX-6300 can support?

[dapandaa]

So I'm just wondering will the fx-6300 work with a 2133mhz ram?
My motherboard does support it, but some people say that the cpu has to support it as well. I haven't find any exact answer, alltought 1 forum said that 1866mhz is supported but how about 2133mhz? thanks in advance.

Officially it supports 1866Mhz.

Officially it supports 1866Mhz.

Yeah officially, but I'm just wondering what would happen if I would run it with 2133mhz ram?

Officially is actually UP TO 1866 at 1 DIMM per CHANNEL. AMD sets the freqs as the high side of the top of the line CPU in a given serious, most all 8150, and 8350 CPUs can handle 2 sticks of 1866 (4GB sticks, which is what they tested with), some 1866 w/ 8 gb sticks and a few can touch 2133, for a 6100, have seen some hit 1866 w/ a 2x4GB config...If pushed some can do a little better, have seen 1 (one) of yours hit w 2 8GB sticks...The FX series is technically a 1333 native CPU, that was originally designed to be slower at spec, but they raised the multiplier so that the upper end could touch 1866 and make it look better than the similar Intel as far as base freq support....if Intel by default had set the multiplier on a 3570K it could run 32GB of 2133/2400 right out of the box

Thanks for replying so fast but as I figured it out, the fx-6300 will actually run just fine with 2133mhz ram.
So I think I will go with the G.Skill Ripjaws Gaming 2133mhz 2x4gb, so I still have some upgrading space on my motherboard.

Let us know how it goes, if any problem, yell out, once in you can use CPU-Z in the memory tab, to check the running freq it will show as half the 2133 or 1066, if it shows 667 or 800 it is running at the mobo default and not 2133

There really is no reason to have that fast of RAM for gaming.

 

[Tradesman1]

It can show a slight increase, and DRAM freq also depends on what else you do, and what one wants.....I just worry the 6300 won't be able to support it, many if not most 8350s can't run 2133

 

[dapandaa]

But I also do video and photoediting so faster the ram, faster ram previews. But yeah I know now your saying I should get a intel for editing and so on, but I'm pretty much on a budget so it's just too overprised imo. And yeah I will also upgrade my ram later on to 16Gb's so that's not going to be a problem.

If I would go with the 1866Mhz just to be sure, will it work just fine with one 8gb stick of ram? so I don't need to buy those dual ram thingys?

When you upgrade RAM, it's advisable to buy an entirely new kit. Personally, I wouldn't even mix RAM of the same make and model if they're not from the same kit.

And why not go with the FX 8350, then?

And you want to have two sticks so that they run in dual-channel mode.

 

[Tradesman1]

As iHog said best with a single package of DRAM and better with two sticks as they can dun in dual channel which typically can be 10-15% faster than single channel with 1 stick

Ok thanks, I think I'll go with a 2x8gb 1866mhz if I get the money for it, or just with the 2x4gb
and for the 8350, I don't really get a advantage from it, 'cause almost all games can handle 4 or 6 cores max and on a single core performance, It's not that much of a difference that i would pay an extra of almost 100$ for that. And yeah maybe the newest after effects can support more than 6 cores for sure, but yeah imo I don't think its worth 100$ :s

Most AMD motherboards support up to DDR3-2400 via OC in the BIOS. Which means you can buy 2400 MHz RAM and manually set the timings in the BIOS without changing voltage.

He should be fine. My brother is running 2133 MHz RAM in his just built system (2 days old)...and he manually entered the settings in the BIOS on his Asus Sabertooth board.

 

[Tradesman1]

Well the 8350 also is faster and OCs better, so if going with AMD, the 8350 will keep you happy longer, as you mentioned it often comes down to the budget (and to me, balancing the benefits of what fits in the budget)

But you said you're doing video and photo editing, which the 8350 will help out a lot in.

I run an FX-6350 with 16g of 2133 ram @ 2200 OC'd. Note , I've been running it that way for over a year now with zero issues ever.
The spiel given about how AMD is "native @ 1333 is a load of hooey to say the least.

It's all about the JDEC and the XMP profiles...
Anyway..
If your MOBO supports it , so will an AMD chip , plain and simple. Note; some boards may require a couple of clicks , i.e. manually set it. But that's fine , while you are at it , overclock it a hair or two.
And to really square things up nicely , up the voltage on your northbridge by 0.01

Intel chips - diffusion process location = China
AMD = Germany

Built in remote killswitch Intel = yes
AMD = hell no

Chips that can run all of their cores at once and at maximum power indefinitely = Only AMD

Built in memory controller issues , voltage leaks and memory leaks - Intel win this one all day everyday

Chips that relay upon another manufacturers technology = Intel , specifically the AMD64 instruction set.

It's funny because I was obsessing about "upgrading" my RAM from 12GB of PC1333 to 8GB of PC2133. The results were interesting to say the least! With PC1333 I was able to OC my FX6300 significantly. It would run happily at 4Ghz with no issues. However I discovered that the PC2133 really destabilized the system when overclocking. Yes I could eventually get it to run stable at 2133 but without any OC. As soon as I tried to OC, even by the smallest amount, the system would fall over. I then found that by reducing the RAMs speed to 1866 or 1600, I'd get stability but never with a worthwhile OC. My experience so far is, save your money and stick with 1333 or 1600. Anything faster makes no noticeable difference and totally destabilizes the system.

It's odd.....Intel 4th gen CPU's that's advertised to hold 1333/1600 RAM can easily & w/out troubles run 4 DDR3-2400 modules w/out any issue, and AMD CPU's, even if the MB supports the same, are restricted to just one 1866MHz or higher module per channel.

In other words, one (per AMD spec page) can only support 1866 RAM in two slots (one per channel) with FX series CPU's, DDR3-1600 in all four, assuming a MB with that many slots, most modern MB's has that many with a few exceptions.

These are the type of issues (prior to Ryzen) that's held AMD back, not so much that their CPU's are total crap, rather the support, and to a large degree, memory controllers, which should be able to be fixed during production, as the box that my AMD FX-8350 came in has a date of 2015 stamped on it, didn't note what was stamped on the integrated heat spreader or IHS (where we clean & drop an oat sized portion of thermal paste). If this were indeed a 2015 release, the issue could & should had been addressed & fixed, as many will be still running these chips until at least another gen comes around (whatever the successor to Ryzen may be).

It's not unreasonable to expect to replace an otherwise good running CPU over a new release, unless one can benefit from the features & secondly, justify the cost, as AM3/AM3+ MB's & CPU's are priced to move. Forget the gen afterwards, the only advantage was PCIe 3.0, the APU's aren't as powerful as the Bulldozer chips, and even Ryzen didn't give onboard graphics, to which I'm glad, that should be on the MB's back, the way we always knew prior to 1st gen Intel 'i' series, AMD would later follow with APU's. A CPU should be just that, it's the duty of the GPU (onboard the MB or discrete card) to deliver graphics.

Still, this RAM issue stinks, if Intel could advertise just 1333/1600, and run 2400MHz in all 4 slots, than AMD in advertising 1866 should do the same. Or did Intel deliberately played down their own specs? While I don't feel that running 2400MHz RAM on a 24/7 running machine is a good idea, pushing memory controllers to the limit & beyond, a few hours per day does no harm. The heart & soul of a computer is not the CPU nor RAM, rather the MB, which sends the signals for all components to do their job.

Therefore, it's not unreasonable to expect a CPU that can run 1866MHz RAM to also do 2400MHz, especially since Intel's specs is 2-3 steps lower.

Something to think about, and nowhere does it say on the Intel site (for 4th gen Haswell CPU's) any capability of 1866MHz RAM, let alone two steps forward to 2400MHz, yet with XMP Profile #1, can run it in all 4 slots. Are memory controllers that much costly to ship with newer batches of CPU'? Not every FX CPU was manufactured in 2012, some were manufactured three full years later, others weren't around at initial Bulldozer release.

Ryzen solves those problems now...
