Failing Ram

[Teemslo]

Just built the computer
Gigabyte 880GA-UD3H Mobo
Consair XMS3 Ram 1600 mhz

Was having random freezes getting worse all stick fail memtest on the block move portion... and ideas? is it possible I got 8gbs of bad ram? 2gig sticks Thanks I'm pulling my hair out lol

If you're running memtest, then you must be familiar with Overclocking. If you're overclocking your CPU without altering your ram timings accordingly, you'll burn out your ram almost instantly; because the OC'ing of the cpu will automatically OC the Ram, so if you go above what the ram is rated for BAM busted ram, pc won't post. Though since it's only freezing then you're ram should be fine for now, you just need to halt and revert all overclocking until better educated Though i'm only guessing you're overclocking...i could be wrong lol

No it's not OC'd at all running stock @ 2.8ghz
Here is the thing memtest 4.0 @ approx 30% at Block move it just thows errors all the way up to 1mil+
With Memtest 3.5 ram checks good :/
Ram is set at 1.65v
Timing at 9-9-9-24
1600mhz
No idea what's cause the issue... ram is Corsair XMS3 DDR3
Mobo 880GA-UD3H

Try altering your tRAS from 24 to 26. And then re-run the memtest. (also is your ram set to 2T?)

 

[coreydmorton]

Just curious, are ANY voltages on your computer altered, and i mean ANY of them? Are they all at stock volts?

I use Memtest86+ 4.20 which is better imo.
http://www.memtest.org/
I test ram one stick at a time first to isolate the faulty module
I do this at mobo defaults then at vendors specs.

 

[Teemslo]

ok I'll give 4.20 a shot, 4.0 fails me everytime, any slot with any of my 4 sticks of ram gets to 30% the block test and blows error codes. Getting very frustrating if I say so myself.

 

[Teemslo]

Also windows memory tester sometimes fails... and sometimes doesn't after messing around with the settings last night I haven't had any issues this morning with lock ups.

 

[Teemslo]

Also this is what I'm seeing on Memtest86+ 4.20

It's still not going to help you until you test one stick at a time.
You have to isolate the bad stick.
At the very least find two that work together with no errors.
Then you can rma one kit and still have the use of your pc.
I doubt you have more then one bad module.
I've rma'd to Corsair before and that's what they instructed even though only one of my 4 sticks was bad.

He's right, but i thought you did that, but apparently maybe not hah It's really important you test each individually to see which one is screwed up. If you single out the stick that's having issues, stop using it, besides....you won't see much (or any, really) difference with only 4gb ddr3, instead of 8gb.

 

[Teemslo]

I've tested them one at a time, that error screen is from one stick running the test, all 4 stick give the same error

 

[coreydmorton]

Then unless you're NOT using stock timings on your ram, then there must be some overclocking on your cpu that you're not aware of to screw things up....i swear you're oc'ing your cpu and maybe you don't know it? An altered FSB (overclock) will automatically oc your ram, which will make stock timings unstable! Which would also explain why all the sticks are not working. Are you 100% sure your cpu is not overclocked, or perhaps your motherboard is automiatically doing this through some option you accidentally enabled (like turbo safe overclock for example, enabled through the motherboard) Throw me an update if you're 100% sure your cpu is not overclocked! thanks!

 

[Teemslo]

No I'm not oc'd at all running stock 2.8 ghz show in the screen shot, also checked cpuz just to make sure something I was missing...

Hmm you're right, your bios reported the stock speed. Can you take a screenshot of the CPU-z MEMORY TAb and the SPEED TAB?
That would be very helpful so i can see your FSBRAM plus your recommended timings.

Hey, huge question. In your motherboard settings is your DRAM Voltage set to auto? If so might not be giving your ram enough voltage, i think your ram needs 1.8, and according to some review some motherboards set the voltage automatically to 1.5 for your ram which is not nearly enough. (Also it could be overvolting as well, just set it to a manual 1.8 and see if that works!)
edit: i just read that you said your ram is set to 1.65, so first lower it to 1.5 and see if that helps, if not then try 1.8...i have a strong feeling either 1.5 or 1.8 will be the magic voltage to get your ram stable, let me know!

 

[Teemslo]

yes it was set to auto, which was 1.5v I tried bumping it up to 1.65 which is what the ram is spec'd at and still got the same 1mil+ errors. Here is the screens you asked to see I hope it helps

oh no, those pics aren't high enough quality to read all the numbers i need.

 

[Teemslo]

That's because I swapped it out with some ddr3 1333 ram I had to see if that was causing the problem... nope still crashing... and still giving me errors, on a side note the screen goes black then a green screen comes up.... and then restarts.

 

[coreydmorton]

I just noticed something. Your ram is running at 669.8 which is way less than the 800mhz it's supposed to be running at.... SO your ram is underclocked! Which is because of the CPU btw, which gives your ram a 3:10 ratio (3/10 x 669.8=200.88) Since your cpu is at 200fsb it's underclocking your ram to match the cpu, which would be more stable....but maybe your ram doesn't work well when underclocked! So try overclocking your CPU!! Try a FSB of (800x(3\10)= 240. Make sure your voltages are all set to auto. This should bump your ram up to 800mhz (dual channel which is 1600mhz) because your ram's frequency is only 669.8x2 (1339.2). So just OC your cpu. Tell me whether or not the ram likes the overclock.
ALSO, don't go over 800mhz, as that's BAd. ALSO ONCE YOU GET TO 800mhz, ALTER YOUR TIMINGS TO 9-9-9-24 (which it is already at) and also change the tRC to 40 (which is at 33 right now).

 

[Teemslo]

In fact It just crashed as we where talking.... 3 times in the last hour

 

[coreydmorton]

Wait a second...what's your PSU?!

Did you also check if the error occurs with one stick even if you place it in a different slot? It could be that your RAM slots are faulty too.

You should be able to run the RAM at lower than stock speed. The SPD should have a profile for 1333.
