BSOD on memory management 2133 mhz ram

[dani3lc]

Hi guys im new and need some help here

i build up a budget gaming pc with the spec as below

- Asus A88XM-A motherboard
- AMD A10 7850k APU processor
- Apacer Ram Desktop DDR3 GIANT II 8GB PC2133
- AVF PSU EXTREME POWER 750W

I make a clean install of Win8 Pro. I read on the forum on how to choose the profile on getting 2133mhz ram which i think i did it correctly and even upgraded to the latest bios update as well.

Here is where the problem. my desktop BSOD randomly once in awhile and mostly cant even past 24 hours of stability. been frustrated fixing it till past few days i tried lowering it down to 1866mhz and basically i got 48 hours of non bsod. so can anybody help me up here i wanna fix this up but i got no experience on ram management at all. from what i read in the forum would it be cause of :

- Ram not certified on the vendor list on asus site?
- Auto Tune voltage on 2133mhz on bios?
- Faulty on my ram or mobo?

PLEASE help me......i already try to tune the voltage up to 1.25V but still i got bsod. i could stream movie, play games like dota 2 and surfing the net like usual and it looks normal though.

i had the minidump file though i could upload if needed.

Run Memtest.

The is a pretty cheap PSU, usually that means junk or close to it (RM 85, or about $25).

That may not be the only cause of your problems, but I would see if I could exchange that for a better unit, like one from Antec or Coolermaster, or a better brand that is available to you.

As for the memory, I would run it at the lower clock speed, as it seems to be somewhat stable there. I doubt you will notice a difference with the higher speed anyway.

 

[dani3lc]

yeah as since im running only the apu graphics i thought that i won't need a much higher power psu though. well as apu runs on better memory frequencies so i thought clocking it higher could have better gaming performance though.

seriously having that psu could affect that much problem??

 

[Ketchup]

Yes it can.

You could get buy with a much lower-rated higher-quality unit.

If you bought this off a website, can you send a link?

 

[dani3lc]

well i bought this from a local shop on my area and it mention that since i running only the internal apu graphics that was sufficient enough as voltage can be tune on the bios..

this is the model that i bought

 

[dani3lc]

i have this older

Gigabyte PoweRock 420 psu

so is this better shud i replaced for it??

 

[Ketchup]

I would definitely give that Gigabyte a shot. Should have enough power, depending on how old it is.

On the site you mentioned, this looks like a good unit.

[dani3lc]

so which should i actually do 1st?

some forumers do suggest me to tune the ram timings which actually i got 0 knowledge on how to configure it or just get a new psu and try???

 

[Ketchup]

Set RAM to 1866. Let it use the default timings.

Swap out the power supply for your Gigabyte.

Let us know if the problems continue.

 

[dani3lc]

well actually i set before on 1866mhz on default timings and on the crap psu.....and i got no bsod for at least 48 hours which actually i think it is on stable situation due to frequent bsod everyday at least once or twice on 2133mhz.

so im quite confirm having it on 1866 its stable

 

[PliotronX]

I get the memory management frowny with too aggressive of RAM settings in 8.1 as well. Try setting just tRCD up a tick and/or voltage up a notch or by .25v.

 

[dani3lc]

well my default voltage on 1.1x at 1st

i already try increasing up to 1.25 and 1.3 before and i still get bsod

 

[Drummerdude]

again, run Memtest

 

[dani3lc]

well just a small question though since i can downclock it stable on 1866mhz doesn't it means my ram should be good? still need to do memtest? sorry to ask i really have 0 knowledge on ram management

 

[Drummerdude]

If you downclock, and it's stable...what do you define as stable? As in, you can run for over a week without a single bsod? No app crashes?

 

[dani3lc]

well i din try for a week but based on my current situation my comp doesnt survive more then 12 hours - 15 hours on 2133mhz

while when use the 1866mhz i have try idle it for over 48 hour-52 hours and have 0 bsod at all

 

[Drummerdude]

Then either the ram just can't handle the oc, or you're undervolting the ram.

 

[Drummerdude]

Also, as per the manufacturers website, the ram is designed to run at 1.65 volts, so I'd say you're undervolting the ram.
Here's a link to the ram http://ap.apacer.com/products/Giant-II-DDR3-Dual-Channel-DDR3-2133/

 

[dani3lc]

im sorry but as i mention i got 0 knowledge on ram management. What do you mean by undervolting the ram?? you mean the timings??

i put it on auto as Set under the xmp or docp profile though ....please advice me what to do.....

 

[dani3lc]

you mean the voltage which i increase from 1.1v to 1.3v before??

i need to put it at least 1.65?? as mention on the link???

 

[dani3lc]

weird the link you put written the CAS latency on 10-10-10-30 but base on CPU-Z and the xmp profile that it set automatically it is on 11-11-11-30. So do i need to change the timing to follow as well??

 

[Ketchup]

you mean the voltage which i increase from 1.1v to 1.3v before??

i need to put it at least 1.65?? as mention on the link???

Hmm, the DRAM voltage goes from 1.35 to 1.65. As Drummerdude mentioned, if you set this to 1.65, you may been able to set this at the higher frequency.

1.1 sounds like maybe the southbridge voltage, which you shouldn't need to adjust for anything.

You will notice even less of a difference changing the timings than you would changing the frequency, so I would let it stick with what works.

 

[dani3lc]

well i just check bios though, all my settings are comes in default and its based on the correct figures...i feel more faint bout it now you can check the image .... you can see the Dram Voltage is as mention on 1.65 and the timings are as follow 11-11-11-30....should i increase the VDDNB voltage though??? i really got no idea whats the problem with it....

Your VDDNB voltage is essentially your north bridge voltage. It controls Memory timings, and essentially, the entire upper half of your motherboard. Your DRAM voltage is just that, voltage adjustment for your ram. It's stock at 1.65 volts. You can try bumping that up one jump ( if that's an option ) or up from 1.65 to maybe 1.7 or 1.75 even. Also, if the link says that the default timings are 10-10-10-30, then I'd force those timings on your motherboard. Some motherboards, by default, run " safe " timings. Mine does. I personally run Crucial Ballistix Tracer DDR2, and the stock, advertised timings are 12-12-12-14, and my motherboard defaults to running something like 15-15-15-18 or some nonsense like that. The ram, on the motherboards timings, runs sluggggggiiiiissssh. But when I force the timings and proper voltage (2.2v), man, they flat out run!
