AM3 Socket - Ram Not Detected [SOLVED]

[GKirev]

Hey guys. I couldn't troubleshoot this myself so I'm calling out here for help.

The hardware:


Processor: AMD FX-8350 @ 5 Ghz
Motherboard: M5A99X EVO R2.0
Cooling: Alphacool Block + Custom Loop
Memory: 2x8gb HyperX FURY 1600 @ 2300 Mhz
Video Card(s): Sapphire 7970
Case: Thermaltake Mozart
Power Supply: Dark Power Pro 1kW

**** Turn on pc as usual, do some facebook, etc. - random freeze ****

System has been running on this overclock for more than 1 year. It's sufficiently cooled and powered.

Troubleshooting:

Reboot.
- 1 long 2 short - Ram not detected (asus motherboard manual)
- CMOS reset (didn't work)
- re-seat ram (didn't work)
- clean all 4 DIMM slots and sticks (didn't work)
- re-seat sticks 1 by 1 on random places (didn't work)
- try working ram from another pc (didn't work)
- re-seat gpu (didn't work)
- try other working gpu (didn't work)
- re-seat all power supply connectors (didn't work)
------------------------------------------------------------------------------
Things I am about to do:
- re-seat CPU
- clean motherboard pins, connectors, etc.
- inspect for visual damage
- throw the motherboard away



Am I missing something? Any suggestion Is appreciated!

------FIXED IT------

- took the cpu cooler off
- took the motherboard off the case
- cleaned the DIMM sockets with alcohol
- reseated the cpu(didnt work)
- reseated the cpu and changed the DIMM slot (didnt work)
- cleaned the cpu pins with alcohol and a brush
- cleaned the cpu socket with an air can (compressed air)
- worked. Holy sh*t.


-----------------------------

No visual damage to the board. Nothing. What do you guys think?

RAM issues do not lie with the chipset. Like Intel CPUs, AMD's AM3+ CPUs have an IMC integrated onto the CPU.

Try memtest, run memtest from a USB drive for a few hours (5 hours is what I would do) to see if you get any errors. If not, try and get a hold of another RAM kit. If that one runs into the same issue, you may want to RMA the board.

The motherboard does not have pins; the CPU does. Either way, you shouldn't be touching the pins before we can make sure that it's not the RAM that is the problem. Have you tried the MemOK feature on the board? Is the light lit?

Read my post again. I can't even post, because my motherboard doesn't see my RAM. It's like you don't have any sticks plugged in. I know that the AM3 female socket on the mobo doesn't have pins, i was talking about the power pins, etc, on the motherboard. Yes it has a MemOk button, but whats the use of it, when it doesn't detect memory. My memory is good.

I verified that the current sticks are ok, and I used a couple of other sticks from a working machine. 101% Not a RAM stick issue.

It looks like the board needs to be RMAed?

If it doesn't help to reseat the RAM (do try this again because with my 16GB Fury kit, the system would boot but not post, and after countless tries at reseating, I realized that the DIMM slots were really stubborn and the sticks weren't actually seated properly despite looking that way), maybe it's time to contact Asus. It's unlikely that it's a problem with 990X or SB950. Can you get another AM3+ CPU for cheap (like, an Athlon II AM3)?

By the power pins you are referring to the DIMM sockets?

 

[ne6togadno]

try cpu in other pc. if it isnt cpu then it's mb.
does psu start when you hit power button

First thing I would do, is set system back to standard clock, both on ram and CPU. If that works and system is stabile after running prime and memtest, then the problem (is) either biosupdate or your new ram just wont work properly at those speeds.

Eventually try to pump up the voltage to your ram, by 1 knotch i bios.

... set system back to standard clock, both on ram and CPU. ...

cmos reset=set system back to standard clock, both on ram and CPU

 

[Ace_Jambo]

So it seems no one is reading what OP has said. It seems that you have done all you can without swap testing with other hardware. If you can test the CPU on another board... but most likely the motherboard.

The motherboard may still be under warranty. If you can pin point the issue to the mobo, send it to ASUS.

 

[GKirev]

Thanks for the tips, tabascosauz, I appreciate your help and I totally agree.

By the power pins you are referring to the DIMM sockets?

No. I'm reffering to the 24pin and 8pin motherboard connectors - usually this is a stupid idea , but just in case. My plan is to find a cheap CPU just like you said and test the system. If it fails - throw the mobo away, if it works, throw the cpu away.

@GKirev make sure you take plenty of high-res pictures of the board before you send it off, if you decide to RMA. I've heard way too many horror stories about ASUS AMD motherboard RMAs, especially regarding suspicious physical damage that wasn't present before the RMA. That way if they try to shaft you and refuse your RMA based on "physical damage", you will be prepared.

he will deal with local distributor/reseller of asus and most likely will get mb replaced (or refunded if new mb of same kind isnt available). distributer will have to deal with asus and their rma but that is distributer's problem.

Your board is not rated to run the 9590, so taking your 8350 and clocking it to a 9590 speeds is the same thing. You are frying the board.

 

[GKirev]

I don't think so. I have installed thermal probes on the VRMs and chipset. Both have never gone above 60 degrees C. My CPU is cooled by an alphacool nex*something block with microchannels and liquid metal, lianli DC pump, 3x120 and 2x120 rads. As I said it has been running on this overclock for more than a year, stable.

 

[Cybrnook2002]

Over-clocks are gambles, what you get one day does not mean you will get it a year later. It's not the CPU temps that are the concerns, its the NB/SB chips on your board as well as the VRM's. That is likely what is now failing due to being run outside of their boundaries for a year now. When it fails, it would likely be the same as pulling your RAM out while the system is running.

There is a reason your board is not rated for 9590 speeds. Only a hand full of boards are certified to run those chips. For specific reasons of NB/SB/VRM capabilities.

Personaly i wonder what the power draw for your 5Ghz overclock is and how it has effected your motherboard over a year

can you smell the Fried chips ????

You may not have overcooked that motherboard but you have caused lots of electrical stress to it by running such a high power draw over a years overclocking maybe its decided its had enough and wants to wave you goodbye
The higher the power draw the more wear is caused to electrical items

electromigration
and the problems it causes
https://en.wikipedia.org/wiki/Electromigration#Practical_implications_of_electromigration

short excerpt
Electromigration decreases the reliability of chips (integrated circuits (ICs)). It can cause the eventual loss of connections or failure of a circuit. Since reliability is critically important for space travel, military purposes, anti-lock braking systems, medical equipment like Automated External Defibrillators and is even important for personal computers or home entertainment systems, the reliability of chips (ICs) is a major focus of research efforts.

Due to difficulty of testing under real conditions, Black's equation is used to predict the life span of integrated circuits. To use Black's equation, the component is put through high temperature operating life (HTOL) testing. The component's expected life span under real conditions is extrapolated from data gathered during the testing.[3]

Although electromigration damage ultimately results in failure of the affected IC, the first symptoms are intermittent glitches, and are quite challenging to diagnose. As some interconnects fail before others, the circuit exhibits seemingly random errors, which may be indistinguishable from other failure mechanisms (such as electrostatic discharge damage). In a laboratory setting, electromigration failure is readily imaged with an electron microscope, as interconnect erosion leaves telltale visual markers on the metal layers of the IC.

With increasing miniaturization the probability of failure due to electromigration increases in VLSI and ULSI circuits because both the power density and the current density increase. Specifically, line widths will continue to decrease over time, as will wire cross-sectional areas. Currents are also reduced due to lower supply voltages and shrinking gate capacitances. However, as current reduction is constrained by increasing frequencies, the more marked decrease in cross-sectional areas (compared to current reduction) will give rise to increased current densities in ICs going forward.

You got it, seeing as a 9590 runs a TDP of 220. Clocking a 8350 up to 9590 speeds (you will not get that on stock volts/amp draw) will yield roughly (If not more) draw than an already binned 9590.

 

[cdawall]

Board or CPU likely bad. Just a guess, what was your NB volt set too?

A 9590 is only a 4.7ghz chip, 5ghz is turbo clocks, so his 8350 will draw more power than a 9370/9590 at those speeds.

Correct, so his chip clocked at 5ghz is the same as a 9590 in full swing. We are on the same page

SYSTEM DOES NOT POST

So explain how to do a mem test on a system that does not post ""Please ""

"" PRETTY PLEASE ""
i do want to learn how this is done as no doubt other people do also
35 years of fixing pc's and i have always had to have a pc boot to test its mem in system

And the OP would like to know as well i expect

 

[cdawall]

Probably not. 9590 is binned for 5ghz the 8350 will typically take more voltage consuming more wattage etc.

 

[Cybrnook2002]

Killing me boss, that's what I already said 6 posts up. Again, we are on the same page, no disagreement or confusion on my end.

Clocking a 8350 up to 9590 speeds (you will not get that on stock volts/amp draw) will yield roughly (If not more) draw than an already binned 9590.

You may have the last word now.

Reseat the CPU as you mentioned, if that fails its either the CPU or MOBO. Buy a cheap CPU and try that, if it fails sell the CPU and get warranty going on the motherboard.
