Added more RAM and another hard drive and my fps dropped

Ok i decided to get a new monitor at fry's,but then shortly after buying it i decided to return it and wait till i could get the screen i really want(but can't afford right now)but i ended up having to get store credit,cause if i went for cash back they would charge a 15% restocking fee so i decided to get some ram and a HD but they were low on both i found a Hitachi 2tb for 123$ and some Corsair Vengeance LP 1600mhz ram(for 49.99) cause i need the ram to fit under my hyper 212+,i installed it all and it did not boot at first but i think that was cause it was not seated right,and the ram was running at 1333 mhz i set it to 1600mhz,and then booted up windows,and it is running fine and it sees all 16gb just fine,but my fps has dropped and i don't know why.

My current ram:http://www.neweggbusiness.com/Product/Product.aspx?Item=N82E16820148435

The new ram:http://www.newegg.com/Product/Product.aspx?Item=N82E16820233186

And i have done nothing to the HD yet,but i was going to move all my games onto it.

Also and exampale of the fps drops are i used to get these scores:(these are the only games i have tried so far and both are at max settings )

Dirt 3:1080p Min:63.45 Avg:89.15 

Batman AC:1080p Min:8 Max:71

Now i am getting:

Dirt 3:1080p Min:24 Avg:60

Batman AC:1080p Min:4 Max:54


What could be causing this? And how can i fix it?

The RAM is mismatched and will cause a big performance drop. You'd be best to remove the Crucial RAM as it is the slower memory.

However, if you need raw quantity rather than performance, go into the BIOS and set the Memory Timings to that of the Crucial RAM. (you will be "underclocking" the corsair RAM.) This may fix the issue, however it will likely not.

Well the reason i got the ram was when my ram usage goes over 6gb i start getting errors saying i am running out of ram and it has even closed out programs on me,and it has been happing more often.

mismatched ram can do that. take out the ballistx, sell it, and get another set of the vengeance if you really need 16 gigs

Ok i took out the ballistx and my fps did not change.... WTF??

did you update drivers?

i have not touched my drivers at all.

Random thought, what DIMM slots is the RAM in on the motherboard?

And also have you gone into the BIOS (or used CPU-Z) to check that the BIOS has correctly set the memory timings?

This was an issue I had with my Vengence Memory, where the mobo never set the timings or the frequency correctly. (though it never affected FPS)

before i had the ballistx in slots 1&3,and when i got the new ram i put them in those slots and the ballistx is slots 2&4, i just looked at cpu-z and the timings for the corsair is set at 9-9-9-24.

Also when i first installed the ram it had it set at 1333mhz.

On second thoughts look at the timings within the BIOS as CPU-Z may be picking up the XMP profile which the RAM should be running at, not what it is running at.

Have you altered the timings and/or frequency within the BIOS at all?

It was the same in the bios,but it was set at 1333mhz,i set it back to 1600mhz,and still the same fps.

Are the  ramsticks working properly, you may have a bad one

Idk if they are working but i am running a in windows verison of memtest,and i am testing as much as i can.

EDIT:Well i tested it with that but got nothing,i have to leave for work at 5pm, should i set up prime95 to run while i am at work?(i get off at 10pm,its a short day lol) If i should do that which should i run?

Well guys i decided to run prime95 blend before i left for work,and it has been running for over 7 hours and no hours so far i will let it run over night,but if it does not get any errors,what should i do?

Ok i put back in just the ballistx and reran the benchmarks,and i am still getting the problem.

What else could be causing the problem??

Have you checked the rams compatabilty with your mobo on the mobo's webesite? there might be a bios update or something.

Nither of the are on the Qualified Vendor List but the old ram had been working fine,and i don't remember getting this low fps before.

Ok guys i reinstalled my OS as a last hope before i go to the store i got these parts from and get upset at them for messing up my pc.

The problem is now gone in fact in dirt 3 i am getting now are better than before the problem i am now getting min:70fps avg:95fps,but i am guess that part came from me getting a newer driver since those tests.

Now i have not put the parts i bought back in but i will and see if the problem happens agian,if it does i am taking these parts back lol.
