Formula-z and FX-9590. Hangs and Freezing.

Level 7

OK, I did some research on this set up as I encounter Freezing and hangs. This is a common issue with this particular setup from what I read. And I've been trying to figure out WHY.

Oh man oh man. underclock it freezes I read..... ya that happens.

Overclock and it Freezes, ya that happens too!!


Well after some testing here and there, Thinking this is figured out.

First let me start with Pstates generated through Cpu-z post here and a small explanation as to what your problem may be.

Processor 1 ID = 0
Number of cores 8 (max 😎
Number of threads 8 (max 😎
Name AMD FX-9590
Codename Vishera
Specification AMD FX(tm)-9590 Eight-Core Processor
Package Socket AM3+ (942)
Extended CPUID 15.2

Instructions sets MMX (+), SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, SSE4A, x86-64, AMD-V, AES, AVX, XOP, FMA3, FMA4
L1 Data cache 8 x 16 KBytes, 4-way set associative, 64-byte line size

L2 cache 4 x 2048 KBytes, 16-way set associative, 64-byte line size
L3 cache 8 MBytes, 64-way set associative, 64-byte line size
FID/VID Control yes
Min FID 7.0x
# of P-States 7
P-State FID 0x22 - VID 0x02 - IDD 18 (25.00x - 1.525 V)
P-State FID 0x1F - VID 0x02 - IDD 18 (23.50x - 1.525 V)
P-State FID 0x1D - VID 0x02 - IDD 18 (22.50x - 1.525 V)
P-State FID 0x18 - VID 0x0B - IDD 14 (20.00x - 1.412 V)
P-State FID 0x12 - VID 0x15 - IDD 11 (17.00x - 1.287 V)
P-State FID 0x8 - VID 0x25 - IDD 7 (12.00x - 1.087 V)
P-State FID 0x10C - VID 0x35 - IDD 4 (7.00x - 0.887 V)

As you can see above, this cpu recommends a cpu voltage of 1.525v @ only a 22.5x multiplier. That's only 4500mhz on a cpu that rated stock of a 23.5x multiplier.

OK. Lets say you post stock. All the power savings are on and stuff, you want to load test at stock.

Take note the horrible horrible v-droop at stock, mine drops down to as little as 1.416v roughly. When disable the Cool and quiet and C6, the board still has a horrible v-drop, mine is reporting still on load 1.416v

At idle, it goes as high as 1.5000v. scratching my head, I wanted to eliminate that droop. So I try and run say 1.5000v @4.7ghz 23.5 x 200. @ load again, this cpu drops v-core pretty hard.

OK, so let's up the LLC or Load Line Calibration. Now, we are running 1.5000v set manually and stays pretty stable.

BUT now the issue becomes heat and still an under-volt at 4.7ghz Pstate requesting 1.5250v.

Uhg. now we run hot hot hot. Gets difficult to control this bad boy FX-9590.

Pulling my hairs out, bumping and bumping voltage up and up creates more heat, thus instant instability.

But hey, the temp readout says we are still in the green and the PC still freezes. Well, I found the freeze happens instantly at load most times while trying to stability test.

My answer to that is still v-droop or just simply not enough voltage.

OK. Now we have established an issue with fighting the boards volt drop problem vs the Cpu's heat out put problem.

So there's a couple of cures, not for sure deals as all of your systems similar to mine will vary in temps voltage and v-drop.

The conclusion to this is quite simple.

A. The board is simply dropping too much voltage to keep stable as you try and load test it, or Core 0 just isn't happy with that type of out come.

B. Cooling is inadequate.

It's basically as simple as that. This particular set up is VERY VERY picky on how it's overclocked because of the Very little head room with temps and that v-droop issue.

In a nut shell, if you plan on buying this setup, be ready for both issues as they WILL occur.

Recommended solutions.

1. leave the board set up on stock and enjoy the v-droop. You'll find load testing even at stock green on, this chip generates massive heat. And I do mean massive. If your not running enough cooling forget it.

2. This setup is intended for massive voltage and massive cooling. What I mean by this is it's designed fully and solely for LN2. You'll find that out when you discover that this thing has a switch for LN2 runs as it's a supposed cure for cold bugs which FX processors don't have in the first place. This has been proven on a very wide range of FX processors and motherboards.

3. Don't by the FX-9590. It's just too hot. Meant to run big mean clocks with big mean voltage and big mean cooling. Buy a lower watt FX cpu.

/quick report. If I have something to add later down the road, you may find it posted here.

Have a nice day/evening!

Level 7
Cpu VID is 1.5250v. Cpu may request this voltage from the motherboard at any given time while running stock. It is recommended to run stock or if trying to overclock to use the 1.5250v VID from multiplier 22.50x and higher.

Under volting (under 1.5250v) will result in eventual hangs and freezing.

Can you cool your FX-9590?

Custom water cooling loop is recommended!
