[SOLVED] Need help with running a stable system on STOCK clocks - Prime95 failing - Page 5

No bro.
RAM for 16GB -> 14000 in prime
RAM for 12GB (without 1 stick in) -> 10000 in prime

Regardless, that's 90% of ram available.

woops, lost this thread somewhere in my sub box ...

Have I told you how I'm awed by your thoroughness in testing? Great work. I would've RMA'd that stick waaay sooner. Especially considering you can run perfectly fine on your other set (or was it a set of 4?) so no downtime really.

One last thing you could test: Perhaps your IMC (or motherboard, perhaps something faulty there? doubt it though ) doesn't like 4 sticks ... have you tried running that faulty stick in place of one of the 3 sticks ? So you'd have 2 good sticks and 1 possibly faulty one installed.

If that fails (which I hope it does) then I'd say it's very very likely to be the RAM.
For 100% certainty you could put your CPU + ram on a different motherboard to rule out the motherboard. A faulty motherboard, however, is kind of a long shot since nowadays it doesn't do much besides connecting the RAM to the CPU. But you know, possibility is there if you really want to be 100% sure.

I personally would just RMA that RAM and be done with it. You've done so much testing already and never a scent of anger in your posts ... Amazing tongue.gif .

Indeed you have - but thanks again smile.gif!

As for the testing:
Well after I decide to stop p95 (it has been running for 24hrs now - 23hrs pictured) - stable on 4.5 ghz - something that was impossible for me to run for more than 3hrs with 4sticks in or at least that particular stick in.



I will do exactly this:
-Put that stick on its own -> see if it fails within 30mins of prime - I have a very sneaky suspicion that the RAM when COLD (this might sound crazy but still) doesn't fail - but after being used for 1hr of it being used, will fail like a hot potato
-If it fails, then go ahead, for the heck of it, and put it in with 2 other sticks, as you said, as see if it fails.

If it fails either or, I'm RMAing it (and all the sticks, as I have to) with no exceptions.

If it doesn't fail however....I'm scratching my head.
Either, IMC doesn't like 4 sticks, or 16GB
Or the motherboard....oh god, please no - doesn't like 4 sticks.

Just thought to fill you in in a little story of ASUS and RAM sticks:
Had a p5K premium, and it wouldn't run in a dual channel configuration.
I even RMA'ed it, in fact 3x, and each time asus would say nothing was wrong with the board.

What happened?
Well I lost £50 on postage - then found out on my own, that my E6500 processor, was too new for the motherboard, and thus due to me having more ram, the BIOS was at fault, as it couldn't cope with dual channel 4GB - thus meaning I was stuck for 2years on 2GB MAX, running on "single channel".

Yes, thank you asus for screwing with my time and money (I did go to trading standards, for wasting my time with them, but as they are Taiwanese, there was nothing the UK law could cover me on)

Anyway - this isn't the case, as I've updated the BIOS, every time (even just after I got the board) - and more so the processor is anything but outdated/too new for the board lol.


I have to say all this testing has increased my knowledge in computers 10 fold.
Thus why there's no anger. But there is definitely frustration in me frown.gif

fun story - p95 ain't failing with the ram put back in - running 16GB
I'll let p95 run for a few hours.

MAJOR EDIT!!!

Forgot to tick two options in p95.
As SOON as i did, re-ran p95, and got an error with the module in:




Right - to be on the safe, side, I'll get the module out, and re-run p95 for several hours.
No errors = bye bye ram.


EDIT:
Have been re-running p95 for 10mins - no fails with the ram out.
Will give p95 more time

EDIT 2:
I put it back in, but got 1 stick OUT - thus it was running on 12GB with that fail stick in.
AND IT FAILED within minutes.

1000000% it is that stick!
THANK GOD!

All of this time it was that one module, usually it doesn't take long to find a defective RAM module.

well I did thorough testing, before assuming smile.gif
I also PRESUMED everything was fine (thus why it took me over a month to figure it out)
All this time I thought it was my OC - whereas if someone said:
Have you gone on stock, and tried seeing if it is your hardware - I would have.

Took me about 4 days to pin it down to the ram & test it.

Edit:
Re-ran p95, as I went out at night, as I forgot to tick round checking (which immediately showed the faulty RAM fail). - just to be on the safe side, and stability, just in case the round checking and SUM checking was at all CPU related (which it isn't, and is RAM related)

Passed for 6hrs, and now I've stopped it (pointless going more than that as I ran 24hrs already)




I also remembered, after doing the test:
On my friends PC, I didn't check the round checking and SUM options.
MEANING: It didn't fail - tomorrow I'll try my faulty ram on his PC, for the hell of it, with them checked, if they fail, again, it is for sure faulty. Just doing it for the sake of doing it. Will be RMA'ing the RAM tomorrow anyway - but I'm curious biggrin.gif

Thought to update you guys:
My RMA has been taken in, and SCAN have tested it - surprisingly it has failed memtest with their system. Even though with mine it passed.
So I can confirm 100% it was RAM related.

Here's off scan's RMA tracking:

Tested = Yes
Fault found = Yes
Customer fault report =
Scan diagnosis = Failed Memtest

I knew it, one module was finicky, glad to hear you solved the troublesome component! Did you ask Corsair to test the replacement modules before sending them to you? OT question how did you enter [Solved] in your title?

well this is the reseller, SCAN which are sorting out the RMA, not CORSAIR smile.gif!

Warranty info:
http://www.scan.co.uk/products/16gb-(4x4gb)-corsair-ddr3-vengeance-jet-black-pc3-12800-(1600)-non-ecc-cas-9-9-9-24-xmp-150v

Details
Duration: 999 months
Type: Return to base
RTB Period: 999 months

So I'll go to them forever, don't need to deal with Corsair tongue.gif!

This is also really great for my Z77 board - no dealing with asus' non-existent customer service:

As for editing the thread title - just edit thread

I AM THE happiest BUNNY right now biggrin.gif

New RAM came in - P95'ed it whilst I went to Taekwondo - and results are 100% working biggrin.gif!
RAM timings:
9-9-9-24 2N
@ 1.55v (I thought to add the extra 0.5v just in case.





The only thing I'm a little sceptical about is the box it got sent in.
The TAGS correspond with the RAM, however on the FRONT of the box it says QUAD CHANNEL

The box differs from the one I used to have + says quad channel on it.
I was afraid it was the:
CMZ16GX3M4X1600C9

But the kit I bought is the:
CMZ16GX3M4A1600C9

New Pics:





Here's the look of my old one:
