Memtest errors on first run.

[litwicki22]

My pc:
4790k stock
8gb ram
http://www.morele.net/pamiec-corsai...-9-9-9-24-xmp-white-cml8gx3m2a1600c9w-419635/
Corsair Vengeance Low Profile 2x4GB 1600MHz, DDR3, CL(9-9-9-24), XMP White (CML8GX3M2A1600C9W)

psu Corsair 750 RM


So today i run memtest.Bootable from usb. Shortly after test started memtest shows 34 errors. Question. Ram is just fault? Or something other can cause that errrors? Prime95 and SuperPi works stable.

Lets start with why are you running mem test to begin with? Could be anything, are you running them in XMP profile or default? Is the voltage for them correct in the bios?

 

[litwicki22]

Because i was had display crashes in Far Cry 4. And BSOD in system today. So i run memtest. I have running them all on default options I dont change anything in bios. All default. And i have errors in memtest.
Voltage in Bios are 1.529V . Maybe i have that errors because they are low voltage 1.35v , but they working on my mobo on 1.529v?

try memtest 1 module at a time.

Two good siggestions here. To answer your question, it is most likely the errors are pointing to RAM only, which has a lifetime warranty.

Bios shows memory running at auto settings 1333mhz at auto voltage 1.529V when memory its rated for 1600mhz and 1.35V.

I am running Asus Sabertooth Z79 Mark 2 . I bought this memory brand new at a local store and when installed motherboard BIOS shows it running at auto 1333MHz with auto voltage 1.535v ,however its rated at 1600MHz at 1.35v.
Also i have errors in memtest. Can somebody explain me why? Maybe this is reason why i have errors because memory rated at 1.35 is working on auto voltage 1.535v ? any guess? Maybe i must buy memory with rated 1.5 v?

you may have a bad memory module...run memtest with only 1 module to isolate the bad memory..then rma it.

 

[litwicki22]

Yes but why its showing auto 1333mhz and 1.53v on bios? When memory is rated for 1600mhz and 1.35v

Question. Ram is just fault? Or something other can cause that errrors?

Can be other components...
"Please be aware that not all errors reported by MemTest86 are due to bad memory. The test implicitly tests the CPU, L1 and L2 caches as well as the motherboard. It is impossible for the test to determine what causes the failure to occur. However, most failures will be due to a problem with memory module. When it is not, the only option is to replace parts until the failure is corrected.

Sometimes memory errors show up due to component incompatibility. A memory module may work fine in one system and not in another. This is not uncommon and is a source of confusion. In these situations the components are not necessarily bad but have marginal conditions that when combined with other components will cause errors.

Often the memory works in a different system or the vendor insists that it is good. In these cases the memory is not necessarily bad but is not able to operate reliably at full speed."

CPU-Z should tell you the SPD values for those sticks. Memory doesn't care if the voltage is a little over stock, and very doubtful there is a cpu problem unless you are pushing too much overclock.

What overclock and memory profile are you using?

Since it is a local place, the simplest thing to do would be to swap you memory for something else and go from there.

I bought that memory 3 years ago. Which i had socket 1155 with 3770k earlier.
I am using stock system. All is dont OC. Memory on stock settings. Memory is rated for 1.35v but bios is giving them 1.53v. But that doesnt matter ?

My cpu is on 4790 stock. SuperPi and Prime95 Blend 10 hours without error.


I check and on memory compatibility in my mobo there are :
CML8GX3M2A1600C9 with 1.5v


I have
CML8GX3M2A1600C9W ( white ) with 1.35 V There are not in list.

So maybe buy just that
CML8GX3M2A1600C9 with 1.5 v rated if they are on list? What you think? That will resolve issue?

Have you tested 1 memory module at a time to determine the faulty module? How many memory sticks is there in your system?

4. I have 2x4gb in dual.

Can higher than rated voltage cause instability of dram? My ram is rated to 1,35v but mobo gives on auto 1.535v.

the auto settings probably will not cause problems. Have you tried memtest with one module at a time?

 

[litwicki22]

Why sometimes i have errors after 5 minutes of testing and sometimes i can pass 10 hours without errors. ?

 

[ArisVer]

And why do you want an answer to your question when you do not answer the question right above at post number 14?

Easy. It's a litwiki thread. Complain about problem. Get suggestions. Totally ignore suggestions, and repeat complaints.

Now i am 24 hours in memtest without single error.
One time i run memtest then after 5 minutes i have 34 errors. Second time when i run memtest it can go even 24 hours without single error.
And i dont change anything in bios. Can somebody explain me this? This is weird, now i am in test 24 hour no single error. But yesterday i had 34 errors after 5 minutes.

Shut the power off to you computer, attach yourself to a grounding strap and remove and reseat all of the memory modules. Do not touch the contacts of the modules and when you replace them make sure they are firmly and properly seated in their slots. Run memtest again.

 

[litwicki22]

I do that. Still no errors in memtest. Weird, something happen that yesterday i get 34 errors after 5 minutes. Now is all ok . But i must to ask.
When i have random errors in memtest one time they pop up, second time not its related to memory or other part?

 

[rumpleforeskin]

Have you tested 1 memory module at a time to determine the faulty module? How many memory sticks is there in your system?

Have you done this yet?
It will be the quickest way to prove which memory stick is at fault, or if the fault lies elsewhere.

 

[litwicki22]

yes i test 1 memory module at time. And there is no errors. I test again 2 sticks and still no errors. So why yesterday i had 34 errors after 5 minutes if now i can run test 24 hours without issue?

 

[dbcooper1]

What make/model is your power supply and do you have another to swap it out with, even temporarily?

 

[litwicki22]

Corsair 750rm i dont have any other psu

So how is your game running now?
