Blue screen of death with new ram

Just recieved this memory, a 8gb kit: 4x2 sticks of CMZ8GX3M2A1600C9B.

I put in either stick on its own and it seems stable enough, but with both I get this error with a blue screen of death as soon as I get into windows 7.

IRQL_NOT_LESS_OR_EQUAL

then technical information:

*** STOP: 0x0000000A (0x0000000000FA0CE0, 0x0000000000000002, 0x000000000000000
xFFFFF8000360BFD3)

Any help? I'm guessing this is could be a bad kit of ram.. This is a huge pain in the arse. =(

Ive tried loosening the timings and slowing down the clock speed, no difference. Is there a known compatiblility issue with this kit of ram when trying to run in Dual channel mode with certain motherboards perhaps?

Yep MB in sig, I have tried at clock rates of 1333, 1600, 9-9-9-24 (basically all SPD settings).

I've tried booting up with each of the sticks in as singles and haven't yet had any problems, its only with both running at the same time. If it was one stick giving me grief I'd be sure it was a ram problem, but the fact they both seem ok until they're both in together seems weird...
 
On AMD rigs, you sometimes need a higher DRAM voltage than on Intel rigs. Try your DRAM voltage up in the 1.6v to 1.75v range. And, as with Intel, you may also need a small bump in your memory controller voltage to run 4 modules at 1333 or 1600.

Ok, thanks for your help on this, it is much appreciated!

Just a few questions I have on this matter, I'm not much of a memory expert..

Do you think this memory is OK?

What exact voltages do you recommend I set these bios settings to? I'm at a loss here and really have no idea, I'm really paranoid about frying something. :o

I see my Kingstons had 1.9v (!) written on them, is 1.5v far too low so they arent compatible? Am I allowed to feed the sticks more than 1.5v? (just for reference, my kingstons work fine in dual channel, so my board is quite happy to do it..)
 
Unless you have a bad module, the memory is likely fine. Start at 1.6v if it is stable there, don't go any higher. Go as high as 1.75v if needed. If that does not do it, don't forget the memory controller voltage, set it 1-3 steps above the stock setting. If both of these fail, we'll try something else.
 
Just tried in 0.05 increments all the way to 1.75v with no differences in the slightest, as soon as the desktop loads I get the blue screen of death.

I must admit I didnt change the memory controller voltage as that was not an option I had available to me within the bios. I want to make clear that I have the latest drivers installed for everything and have flashed my bios in the past month to the latest version available from gigabytes site.. Any more ideas?

I'm beginning to feel a bit sick that I've splashed out 70quid for dual channel ram, of which only half is going to be usable..
 
would it be the north bridge clock? HT link frequency? these are the sorts of options i have available to me in the same menu as the voltage settings in the bios. Sorry for the hassle!
 
I will ask someone from gigabyte what the correct bios option would be, and have another look through the manual. In the mean time is there any other ideas? Should I just rma the ram and go back to my 2gb set up? :/
 
I don't think the memory is defective. Of course, if it is, you'll need to RMA it but I think this is a configuration issue. Also, be sure that you have cleared the CMOS since adding the new memory.
 
Assuming you're not overclocked.

If you've overclocked let me know how what your settings are for multiplier and frequency (e.g. 17 x 220MHz).

On this screen:



Set Memory Clock [Manual]
Memory Clock [x8.00] - 8x200MHz = 1600MHz

System Voltage Control [Manual]
DDR3 Voltage Control [1.5V]


On this screen:



DCTs Mode [Ganged] - you can try [Unganged] later
DDR3 Timing Items [Manual]
CAS# latency [9]
RAS to CAS R/W Delay [9]
Row Precharge Time [9]
Minimum RAS Active Time [24]
1T/2T Command Timing [2T] - you can try [1T] later

Nope not overclocked at all. Ok, I will set my cmos to EXACTLY this after a reboot and let you know.

EDIT - no this didn't work. i dunno if my windows is botched or what. this is really starting to get on my nerves now, how much voltage should i give the sticks? 1.8v made no difference. And I found the memory controller settings and gave it 3 notches more and it wasen't any different either =/

They're rated at 1.5V.

I'm not sure putting 20% extra voltage through them is a good thing.

The RAM should be in the 2 blue sockets. Is this where you have them?

Final try.

Go into the BIOS and load the default settings.

RAM in the 2 blue slots.

Only change the settings I listed above.

See where that takes you.

Edit

Try Memory Multiplier at 6.66 for 1333MHz, or even lower, just to see if you can get them working.

Tried exactly that, even down to 1066mhz. No joy. I've been browsing the compatibility site for my MB and this ram isn't on there.. But to be honest not a lot of ram from recent times is on there.. Ironically even my old ram (that worked in dual channel) isn't even there. Lol :confused: this is like a bad joke!!
