How difficult is it to run 2133+ ram on an FX cpu?

Hardware Hub CPU

Is it just a small volt increase here or there? overclocking?

 

I am getting an 8350 and will be overclocking it (I've already overclocked a 6100 to 4.6ghz...which is...decent) and want to know if there are any notable challenges running faster ram on that line of cpus.

 

I will more than likely be getting a 2x4gb kit at 2133 cl9 (or 8) and want to upgrade to either 4x4gb, 2x8gb or 4x8gb kits in the future...not sure if slot population make a difference in stability...

Whatever motherboard you have you will of course need to OC the CPU to get those speeds. The Vishera cores are fairly similar to the older ones so I doubt it would be much difference. 

That being said, you know there is really no point to running  high RAM speeds right?

In general, especially if you are gaming, system RAM speed doesn't matter. You won't notice any performance increase. It is just a bigger number. Sorry. 

Plus, high speed RAM is quite expensive especially with low CAS latency for really no performance gain.

Tighter timings are better than a faster speed.

the motherboard is this one: http://www.gigabyte.us/products/product-page.aspx?pid=4417#ov

 

I do work in photoshop/sketchbook pro and the occasional audio and/or video project...I believe the photoshop and video rendering do benefit from faster ram...if I'm not mistaken...

wouldn't 2133 cl9/8 be the best of both worlds?

Well first of that motherboard is crap. Don't get it. Really you want a 990FX board with the 8 Cores. Plus Gigabyte motherboards are meh and prone to VRM failure. 

Get an Asus M5A99FX Pro/Evo. 

Maybe they do a bit but I really doubt it would be worth the amount of money you'd be spending.

Here is the problem.If you check the AMD site on memory bandwidth in < Features > ( Click ) you can see your memory has a limitation.If this were an APU it would be a different story.This is why you should get just stick with a balanced memory module.1866 is Best.2133 is more powerful but for some motherboard.

Unrecognizable an will not increase performance.As for that motherboard.It is considered discontinued.An it will be near impossible to get board driver updates.Driver updates will fix the clock counter timing up your temperature numbs due to a bug.Not because of your processor.It is recommended to get the latest up to date boards.There are only 3 as far as i know that are functioning perfectly.

The Sabertooth R 2.0,The extreme edition board an the Asus M5A99FX R2.0 one.I do not know what country you are in so it is hard to me to tell you which store to get them from.But i have no recommendation.All of them work but all of them suck.No other boards that i have found have been updated or provide quality sound chips.None of them have THX quality sound.Which can be set low.Where the basic Audio adapters you have to turn up almost to the max volume to hear an still do not sound quality on your surround sound system.Choose wisely.

its like, the hardest thing ever. man.

What the fuck are you saying. Please stop. You have no idea what you are talking about. 

2133 will work in those motherboards if the CPU is overclocked. It isn't "more powerful." Please Stop spreading misinformation. 

10

Mostly, it is literally as easy as picking a xmp profile for 2133 in bios but your mb has to support the ram speeds.

^this

As i said.That motherboard does not support higher than 2000.Also to DerKrieger I have a MSI 870A.Fusion Power Edition.and a MSI 785GTM-E45.The company tells me specifically that when some boards are outdated the issue the warning that the board will no longer be supported.That means it will be discontinued.

So this customer will have a discontinued board.It does not support that memory.He needs a new one.That is not misinformation.The word more powerful is a description of performance an not just frequency.It is more powerful compared to lower powered memory.Please do not spread misinformation about me.I will consider it an personal attack.

13

Timings are counted in clock cycles. Higher frequency with the same timings is mostly the same as tighter timings at the same speed.

14

actually lilterally any AMD board that supports veshera arch thats not OEM that supports 1600 or 1866 ram multipliers can run 2133 ram whether the motherboard supports it or not since the memory controller is on the chip itself

the ram multi for 1866 might be listed as 9.33 and for 1600 as 8

ram  FSB

vvv   vvv

9.33*228, set tHyper transport multi to 9, and NB multi to 9 or 10

8*266, set hypertransport multi to 8, and NB multi to 8 or 9

remember to set correct timings and voltages.  since you are increasing the FSB make sure you set the CPU mulit appropriatly, for example if your 8350 is 4.6Ghz then if you change the FSB to 228 then you'll want the multi to 20 and if you set it to 266 then you'll want it set to 17

15

it won't support native, but you should be able to reach 2133 by overclocking your cpu on the fsb.

Thank you. 

IDK what he was trying to say and talking about older chipset MSI boards? IDK.

I believe that if the CPU needs to access a bunch of little pieces of data randomly, really fast like number crunching I think, that's when tight timings are more important as the data is actually getting to the cpu faster, 

but when it needs larger pieces of data like large sequential pieces that's when pure bandwidth is key

I have the exact same mobo downstairs in the basement, it took my STOCK 8150 with it when it melted too

  • Unless you're using an APU (which the FX line is not), overclocking your memory's frequency to 2133 MHz and higher is a waste.
  • The performance difference between 2133 MHz / CL 8 (which is considered a pretty decent overclock) and say 1600 MHz / CL 9 (which is considered standard) is usually negligible.
  • Even if you buy RAM that is designed with a base frequency of 2133 MHz, the performance to money spent ratio isn't sufficiently high to justify buying more expensive memory.
  • It would be far more beneficial to either buy a better CPU or SSD to increase your system's performance than buying RAM that has a few hundred more MHz.
  • The exception to this is the APU case, where the quality of memory and it's frequencies and latencies correlate to performance much more significantly.

Overclocking memory to 2133Mhz with a CAS latency on 8?

 

When you overclock memory, you are increasing the memory frequency, but you are at the same time increasing the CAS latency, hence why overclocking memory is pointing.
