AMD FX-9590 Black Edition memory support

[SuperT3]

I have read all the specs for the FX-9590 in the specs tab here:http://www.microcenter.com/product/423307/FX_9590_Black_Edition_47GHz_Eight-Core_Socket_AM3_Boxed_Processor It says that the memory types supported are DDR3-1866, that's it. And on the Asus Crosshair V Formula-Z ATX AM3+ Motherboard (motherboard i'm getting for my new build) it says that the max memory supported is DDR3 2133. Do I get 1866 memory or 2133? Very confusing! And is there a difference between "AMD FX-9590 Black Edition 4.7GHz Eight-Core" and "AMD FX-9590 4.7GHz 8-Core OEM/Tray Processor"

I absolutely cannot recommend the 9590. If you are only really gaming and some other lighter activities on your PC, I highly recommend opting out the 9590 for the i5 6600k or spending a bit more for an i7. The FX processors are just not worth it anymore, and this is coming from someone who has been using the 8350 since release.

I'd also not recommend it for a new build. I've got one which I used to upgrade an existing build and its performance is, frankly, disappointing. I should have "bitten the bullet" and spent the extra on a new motherboard and an i7. My PC at work, with a Core i7 2600k (Sandy Bridge) actually outperforms it in may tasks, even multi-core jobs such as big compiles where I expected 8 real cores to do better than 4 cores with hyperthreading.

I also had to underclock it and lock the frequency at full to get it completely stable - it tended to cause the system to hang when it went off-load, probably because of the sudden massive drop in power demand. From what I've read, instability is quite common with FX9590s.

Cooling it is also hard work - I use big air (Prolimatech Genesis with 2 x 140mm fans), having found a closed-loop liquid cooler (Corsair H120i) to be somewhat underwhelming in my work PC, but it still gets up to 65°C during long periods of 100% usage.

to answer your question directly, yes you can run DDR 2133 with an AMD FX-9590 on an ASUS crosshair V and get the ram to work at those speeds.

the difference between the retail and tray processors are that the retail (first one) comes with a 120mm sealed water cooler made by asetek, the tray processor (second one) comes with no cooler and you must supply your own.

my CPUz, to give you an idea of a properly set up FX-9590 http://valid.x86.fr/8tm35e

yes that is 5.2ghz at 1.52v and never breaks the 65c thermal limit (usually around 55c max)

its very important that you back the volts off even at stock speeds. mine can go as low as 1.3v and hit the stock 4.7ghz on all cores. takes 1.416v to hit 5ghz stable across all eight cores. maxes out around 5.4ghz with 1.65v (i wouldn't really recommend anything more then 1.55v on good watercooling for daily use)

i have a very good watercooling setup, much better then any sealed unit and probably a couple notches higher then even a well done custom loop (my rad is 360x60+?mm pure copper, single circuit with like 16+ channels and goes for around $300+). i could easily cool my CPU+2-3 high end video cards on just this rad.

you will probably have to manually enter the speed and timings in the BIOS, otherwise its likely your PC will default to DDR1600

will DDR2133 make any difference vs DDR 1866? not really unless your compressing alot of files.

would i recommend a 9590 at this point in time? maybe, maybe not, if your all for AMD and you want to get the best they got right now then yes. maybe hold off for zen and save up some more, just something to think about.

my CPU benched scores right up with a heavily overclocked 4770K and easily beats out most intel quad cores

@Molletts you need a better CPU cooler, i cannot really recommend any air cooler for an FX-9590 and i would recommend something of H-100I caliber and you should easily hit 5+Ghz. also drop the vcore, you should be able to easily back it off to 1.3v-1.35v

its important with FX CPUs that you also make sure your HTT is set to 2600, otherwise it can get bandwidth starved. going higher on the HTT is only really applicable when your pushing DDR2400+ ram speeds.

FX-9590's do not have stability issues when set up correctly. they do require some serious cooling, but so does a highly OC'd I7 so that point is actually moot.

to truly beat out an OC'd FX-9590 with Intel you shouldn't be looking at any intel CPU that isn't a quad core, with HT and a reputation of regularly hitting 4.4ghz+ when overclocking. Almost any modern six core intel CPU with HT will easily match or beat out any FX (they are pricey, but very nice)

Now I do believe what you say is true, but if you were to set up a very nice watercooling loop on any highly overclocked CPU you would see great performance for that CPU. I am willing to bet OP is not as skilled as you, and setting up a system such as you have would require him to do something he has never done. That being said, I believe it would be much better for OP to get a 6600k or a high end Haswell E processor, because out of the box they would definitely out preform the 9590. The work OP would have to go through just to get a stable, high performing 9590 working would just not be worth it if he is only going to play games and other normal things. Anyways, it is all up to OP to decide the direction he wants to go.

Interesting. Maybe mine's a bit duff - I had to overvolt it slightly to 1.5V (offset voltage +0.025V) to get it stable at 4.2GHz and set the load line calibration to "Ultra High" (I think I also set some of the other power-related things to more aggressive settings than default) - that's partly why it runs so hot. It won't POST at 1.3V, even underclocked.

Interestingly, it doesn't seem to throttle at all, even when it exceeds 65°C (turning down the case fans can get it to 70+ quite quickly) - repeated runs of SuperPI return exactly the same time regardless of the CPU's temperature.

I'm still gaining a bit from its large cache and I'm put off of switching to Intel by the cost of Xeons and their associated motherboards (I use ECC RAM which isn't supported on Intel consumer CPUs). Maybe I'll have another play with the settings and see if I can get any further. If I get time, I might borrow the H120i from work and see how that performs, although the Genesis is a bit of pig to remove/reinstall.

Where do you work? Sounds like a fun place to be lol.
