So I've had the 9590 in my computer for a few weeks now, and now that I have some actual games on my computer, it can't play any of them except for EVE Online.



My setup is:

Asus Crosshair V Formula-Z motherboard
AMD FX-9590 CPU
NZXT X60 Kraken CPU water cooler (general temps are 35-44 from idle to high load)
NZXT Phantom 820 Ultra (high air flow)
EVGA GTX 780 Ti GPU
G.SKill 16GB 1866 RAM (was previously using 4GB 1333Mhz ram but had the same problem)

Essentially I can load up games most of the time but only after a few moments, my entire computer just locks up and you can't use Ctrl Alt Delete, or anything other than standing up and manually resetting the entire computer. I have done MSI Afterburner and tested my GPU and that is working properly, I've tested my CPU and after around 3 minutes the entire computer locked up. I have used memtest 86+ and tested my memory and found no errors. I've used Prime95 and ran it for 14 hours on my CPU when I got it and it had no problems (that I can think of) but then 90% of the time when I test my CPU on high load it locks everything up.

The only possible thing I can think of is that the FX CPU wasn't designed for Turbo Boost, since the constant voltage and frequency transitions are what is frying it. Is there a way to just turn it off in the BIOS to make it stabilized or perhaps OC it to 5GHZ without turbo boost so it stays consistently at that speed? I'm not huge on overclocking but right now this CPU to me is a little tiny brick that can be chucked out the window.


[This topic is directly copy and pasted from AMD support and game forum, but also putting it on here since I don't trust the 'forever' timeframe on their forums like I do on here]
 
The only solution I found for formula motherbotherboard was to down clock to 4.0 GHz then work your way up think it will make it to 4.8ghz. Put 850 watt to board and CPU, then 850 watt to GPU so yes 2 PSU due to parts that I had around. The other issue was north bridge was over heating. That is why I down clocked stress tested all cores and passed. Also max motherboard watt I found was 148 max other than that good luck with this CPU until they make a 220watt board.
 


The water cooling was recommended by the shop which sold the cpu. It wasn't a heat issue anyway:

I assure all of you: switching off the turbo mode via bios is the way to go. Ever since my pc is running like a clockwork and hasn't had a single freeze once!
 
I have done just about everything disabling C1 and C6 etc etc have not down tuned proc yet im going to put an antec fan on vrm's first plus I don't know how to turn down the proc lol turned down my 2133 ram to 1866 only time I have issues is running boinc 100-100 75-90 works ok 9 out of 10 times its alot better then it was not as random freezing anymore and im thankful

This is my first comment on this site (fwiw).

After reading the comments, I have a suggestion that hasn't been mentioned here so far.

I have the same CPU/mobo combo, and it turns out that the Crosshair V Formula-Z has an extra 4-pin power connection along the 'top' edge of the board (the top being the side closest to the CPU, with the PCI slots running down the 'left' side, from that perspective). The purpose of this connector, I'm told, is to supply additional power for high-end graphics cards and multi-GPU setups (well really, it's just extra PCI power, but that's what most people need it for). I had this freezing issue for a while, (started with an MSI board, replaced it, then upgraded to the ASUS Crosshair, which *reduced*, but did not eliminate the problem). Since connecting that extra power connector, I've had much *fewer* freezes (maybe 1 per 4-6 hour gaming session, most days). I haven't pursued the problem since then (instead choosing to just live with it for the time being), but that should help a bit, I hope.

Without checking, I'm pretty sure I've also disabled Turbo via the BIOS, and maybe also Cool 'n' Quiet (don't recall atm).
 


I have this same board, though I love to overclock, so I never have actually had C1, C6 or Cool n Quite enabled, Maybe on my Phenom II x6 1100T, which I was able to get 4.4ghz with this board, I remember freezing while playing with clocks on that chip, but 4.4ghz with a 3ghz CPU-NB it was a bit hot but perfectly fine

With my system below, I would freeze after anything past 4.8ghz, this was at low temps, No matter the voltage either. Just boot up, let it sit for a min, then it freezes.

I fixed it by lowering my RAM voltage, I have no idea why this helped. My default voltage was 1.55v Im down to 1.4v at 1600mhz and its been rock solid ever since. I even switched out RAM to match the color theme of the motherboard and it still did the same thing until I lowered the RAM voltage to 1.4v.

Since that fixed my issues, Im able to get all the way up to 5.2ghz with 1.52v. thought for my chip, thats a good jump from 5ghz and runs hot, Im at 5ghz with 1.45v with 25% LLC so voltage jumps to around 1.5v under load. Again I have no idea why.

I also lowered my CPU-NB voltage to 1.16v at 2200mhz and the HT and NB down 1 notch from stock voltage, everything is prime95 stable for at least 10 hours I tested it while I was at work.

 
Good news, bad news!

Good News; I have found that by keeping my CPU at stock 4.7 has kept everything stable.

Bad News: I suffered for 3 days with the stock cooler before I bought a Corsair H100iGTX and anytime I update/flash my BIOS I have to stop it from automatically setting 5117MHz.

My average CPU temp is 18C-29C under heavy load. I would recommend spending the coin on a good cooling solution....or swallow your pride and the cost of an Intel build.......next time Gadget! NEXT TIME!!!

Lol this was a great laugh, thank you all!

I have an 8350 @ 5ghz and want a 9590 as the last chip before Zen hits, if it ever does... I think more of you should stick to basic chips next time as some of you don't know what you're doing at all, with FX disable turbo, it's rubbish, you can keep cool n quiet enabled etc but in your power settings set LLC to high and if you're lucky to own an asus board set the power to 130%.

You're now stable.
Good day!
 
Hi

My setup is

Asus Crosshair V Formula-Z motherboard
AMD FX-9590 CPU

Had the same issue as everyone else for over 12 months with multiply warranty claims on different parts
just started diging through information again and camed across this thread and this video https://www.youtube.com/watch?v=gtF8AZVkUuA
which looks that it helped just by switching off the turbo in the bios, thanks you so much

So what does this actually states , does the processor doesn't support over clocking/working within standard parameters or its the combo of the motheboard and the cpu thats not fully compatible ?. When im switching off turbo i have to reduce the strain on the cpu which should cope in the first place ?
 
I have seen allot of people stable there FX-9590 at 5.0

I have the FX-9590 on a Asus Crosshair V Forumla Z on a Corsair H100i GTX and EVGA 1000P2. Mine is stable at stock 4.77ish at full load 100% (prime95) mine does not go over 51c at 1.44ish voltage (AI Suite). I ran it for an hour and half.

People are forgetting that this MB has (2) ATX plugs for the CPU. There is an 8 pin to the left of the CPU and a 4 pin to the right. This was very unclear to me when I was putting mine together because in the manual it says 8pin or 4pin or etc. It does not specified witch one to utilized or both. People on the forums stating that the 4pin is for CPU overclocking and the 8pin is for primary CPU. I still need to confirm this because it's not in the manual.

You need to realized this CPU is 220w so a very good PSU is recommended and a good CPU water liquid cooler is required for the FX-9590.
 


After seven months of searching and not being able to use my computer to it's full potential, you have given me the solution to the problem! I can't thank you enough!
 
Guys, I'm in the same boat as a lot of others! This is my config I got as a barebones kit from Tiger Direct over 2 years ago, so I'm sure you can understand my frustration with this doing this for that long! When I kept getting this issue, I literally replaced every piece of hardware in my box. :*(

AMD FX-9590
Radeon R9 290X

I've read these posts before, about freezing associated with the FX-9590...and I was renewed with optimism when I saw some different ideas - disabling C1/C5 (although, I need to check about that Cool n Quiet setting, I think it's still on) and locking the voltage.

My bios looks a little fancier than it has in a while...but I believe my C1 was already disabled by default and I went in and disabled my C5. I've done what I can to not use any over-clock...early on, that seemed to be a sure fire way of freezing within seconds. I've danced around my bios but can't find anywhere to force a consistent voltage, if that'd even help...and not sure if there's something to help by adjusting my GHz lower than the norm, if it would help stop the freezing...

Any ideas?
 


I tried everything suggested above in terms of power settings, etc...they helped but didn't solve it.

But as mentioned elsewhere on this thread this is what finally worked for me UNDERclocking the CPU to 4.4GHz...my CPU has been running at almost 100% utilization for about 2 months solid now....

In the BIOS Advanced CPU Core Features, I set the CPU Clock Ratio to 22.00




 


I had this issues on an ASRock 990FX Fatality Pro for awhile on a overclocked 8320, once my voltage passed 1.5v I would just all out freeze, even with no load at all. Though for me a combination of FSB and multi and I was able to get to 5ghz with lower voltage.

I think the power delivery on some motherboards just can't handle the 9590. Have you tried setting the 9590 back to defaults and try disabling the turbo and lowering the core voltage a few ticks. Test for stability and see if its stable at 4.7ghz at a slightly lower voltage. Also, CPU-NB make sure it's set to 1.17v at 2200mhz, which is the normal default for these chips, some boards like to overvolt this and overclock it as well.
The CPU-NB can safely go up to around 1.3v but it will add quite a bit of heat, so it best to undervolt this as much as you can but remain stable.

It's just a suggestion, I can't guarantee it will work for you or not. But I don't think it's the chip it's self, but the motherboards that can't really cope with the amount of power it needs.
 
I had that problem too and the solution I found that worked best is underclocking to 4.3GHZ. I believe part of the problem lies with no available motherboard capable of handling the power needed to fully unlock the chip. I run it on the asus m5a99fx r2.0 and though the cpu temp stays low the actual socket temp stays at 44c and reaches 54c under heavy loads. However underclocking to 4.3GHZ has not only stabalized the chip but no longer freezes the system even when playing heavily modified games such as skyrim and fallout 4 with full enb along with about 300-400 additional mods. This advice worked for me but you may have other reasons for trying to gain full chip usage and as far as I know there is no socket that handles 220watts or the temps created by it even with peltier plate on the back of the socket.
