First of all here are my hardware specs:

AMD A10 Series A10-7870K 3.9 GHz
Gigabyte GA-F2A88XM-HD3
Sea Sonic S12II-520Bronze

This question has been raised several times, but I just want to hear the answers again with my specs in mind. The memory that I just bought is the:

Vengeance® Pro Series — 8GB (2 x 4GB) DDR3 DRAM 2133MHz C9 Memory Kit (CMY8GX3M2B2133C9)

It says 1.65v tested voltage. So my question is, will running this memory on my motherboard damage the motherboard or vice versa or any other component on my PC.
 
Solution
try to manualy set up the memory and not use the xmp ? if you still feel a concern rma the memory you got and go with a 1.5 v kit ?

with any overclocking its a risk but then that chip supports 2133 native , so that speed should not be a issue ?

''According to JEDEC,[3]:111 1.575 volts should be considered the absolute maximum when memory stability is the foremost consideration, such as in servers or other mission-critical devices. In addition, JEDEC states that memory modules must withstand up to 1.80 volts[a] before incurring permanent damage, although they are not required to function correctly at that level''

I guess I would insure you got the latest board bios and reseat the...


You are right, when you said that the default voltage will run at 1.5v, but it will also run at 1333mhz which is very slow for an APU.
 


Wait, what?! I must've missed something. I did just that, but didn't check if the voltage is at 1.5v. Obviously, I'm a newbie, but I'll check on that again and I'll get back at you if it fixes my problem. Thanks.
 
''If you use the XMP profiles on your board, it should run the RAM at its rated speed of 2133MHz @ 1.5V
The board will allow you to OC to 2400, so give it a bash''

that's a yes and no anything according to gigabyte over 2133 will downgrade ??? [ check memory support list ] I seen this on another of there boards [intel] as well so I really don't know what there getting at with all that downgrading stuff ?? either it can or it cant and seeing it downgrades I say it cant

but to achieve 2133 with your memory on that board it should be as easy as setting the amp/xpm profiles of the memory and should run as expected .

One more thing. I almost forgot about this. Before I enabled the XMP, I did a basic windows memory check and also used Prime95 on it. The results are normal. However, after enabling the XMP and doing the same diagnostics, the results returned with an error for both. What happened?
 

Running the memory at 2133mhz is not really my issue since I was able to do it after enabling XMP. However, I just want to make sure that it runs 1.5v or if it runs at 1.65v, it won't damage itself or any other component. Also, after I enabled XMP and started a prime 95 and basic windows memory test, both returned with "hardware problems were detected...". Well not for both, since I can't remember what prime95 said, but it definitely didn't finish the test with a positive outcome.
 


I'll try to check on the AMP (although I didn't see one), later when I get home.

I guess I would insure you got the latest board bios and reseat the memory and start over . overall I really don't see 1,6vbeing a issue and it could be from using the xmp on a amd board ?? so set things up manually

also if you look at your boards memory tested supported page there is memorys listed that are 1.6v under the 2133 list ..

G.SKILL 8GB F3-2133C9Q-32GZH

I'll try to do it manually. If it will still have an error then I'll return it. Thanks for all the information. This is good stuff.
 
I was wondering if the newer bios for that cpu should adjust for that seeing 2133 is now native on the mc ? I was going to point him your way seeing I don't like to give oc advice then something goes wrong ...

this is why I wonder about giga usa don't have the new revisions just the older ones with that beta bios for the chip [Godavari ] support - not much info after that
 
No telling the may be test marketing newer versions in select areas, might even be slightly lower grade versions of the mobo - I hate it when they move things around (locale wise) - I know I wanted Asus to release the Z97 Ranger here in the States (a little brother to the Hero) and they didn't, but in the Z170 mobos the Ranger is availabe saw it at the Egg, but it's $1 more than the Hero (???????) was back and forth with a guy in Australia and the Ranger is $50 less than the Hero - go figure 😉
 
money and hype that's all you really need to know - lol

well eaven with the new revision boards it needs the latest bios for the Godavari chip though its not a beta ? I did see with that chip its preferred to usr the 2133 or faster with the on chip gpu lot of guys going with 2400 and getting all they can from them ??

so witht hat I figured he should not have too much of a issue with the 2133 unless its a bios thing [opinion]
 


The voltage and and frequency are all good now. Thanks for all the support. However, when I tried to run prime95 test on it, it again returned an error message that said (well not exactly this message):

"Fatal error: Hardware problem detected..."

I just got 2 different BSODs. First one said "irql_not_less_or_equal" and the second one said volsnap.sys. Both seemed to relate with RAM. Should I RMA the memory?

Volsnap.sys is the Windows volume shadow copy driver and disk issues. or other corruption might be in play. Classpnp.sys is the SCSI class system. dll control and disk issues will affect it. Run SFC /scannow and then. I would get a test tool like wd's data life guard or seagates seatool to run a test of your drive ??

those two errors can be from a harddrive or controller issue - driver as well memory can have nothing to do with that

you never did say what revision board you run or if you had the latest bios that supports that chip on your board ?

also if you gt rev 3.0/3.1 and you got the drivers or what ever from the rev 3.2/3.3 boards support by accident ??
 


My BIOS version is FB and the revision is 3.1
 
from the gigabyte link I gave above with rev 3.1 you need bios f8-d beta [2.Update APU AGESA code for Godavari support]

don't you see that for revision 3.1 board there is not bios F8 ??? that's a revision 3.2/3.3 bios number ??

so that's why I asked this '' also if you gt rev 3.0/3.1 and you got the drivers or what ever from the rev 3.2/3.3 boards support by accident ??''

the rev 3.0/3.1 bios are not numbered that way

rev 3.0/3.1 bios list
http://www.gigabyte.com/products/product-page.aspx?pid=4727#bios

3.0/3.1 cup support list shows for your chip on that revision 3.1 bios F8d to be used with that AMD A10 Series A10-7870K .....

[AMD A10-7870K 3900MHz 1MBx4 N/A 1050 MHz Godavari 28nm A1 95W ''F8d '']

this is something you got to be sure of and carful about
 



You are a star. I'll correct this as soon as possible and get back to you. I do have this other problem. I'm getting this error message in Prime95: FATAL ERROR: Rounding was 0.5 expected less than 0.4. It wouldn't even last 5 minutes. I'll get the error message after like 30 seconds. Games would occasionally freeze and close too. Overall, I don't think the 2133 MHz speed is not stable. Highest I got is 1866 MHz. Do you have any information about this?
 


Sorry, I made a mistake. The revision is 3.2 and not 3.1 so I definitely got the latest and correct BIOS version.
