Looking to add more ram, would these work together ok? Need help ASAP

post #1 of 11
Thread Starter 
I have this ram.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820104255

And can get this ram
http://www.newegg.com/Product/Product.aspx?Item=20-104-239&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=-1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Keywords=%28keywords%29&Page=2#scrollFullInfo

Would they function together ok with out an issue?
I notice one is 1.5v and the other is 1.65v

The guy who is selling it states, The only difference is that the XMP profile on one wants to default to 1.65v, but I have it operating at 1.5v without issue.

Thanks in advance

I would say yes. I have ran mixed ram ever since I starting building systems, (12 years) and never a problem.
I even have a laptop with different brands and voltage sticks of ram.
my current system I bought 3 4gig sticks and then a year later 3 more, both are same brand.

I've had mixed results....

Check my thread...

Feel free to provide your insight... I'm 50/50 so far. frown.gif

Would I need to set all 4 sticks to the same voltage? He says he runs them at 1.5v fine. But on the specs it says it should run at 1.65v, and mines are 1.5v.

Would I notice any performance difference if they run at different voltages? Or If I run them all 4 at 1.5 even if his are meant to be ran at 1.65v?(If that's possible??)

I think the problem you will run into is that the second kit needs 1.65 colts to achieve the 1600 mhz

That's not how it works. If theyre rated at 1.65 for a specific speed/timing, it means they need at least that 1.65 juice to hit that speed and timing combo....

See the thread I linked above where I've had partial success in matching 1.65v wth 1.5v

Okay, one you misquoted me. I did not write the first part fix that now. Don't write in my username for a quote. Two, you are trying to make a 1.5 volt kit run at 1.65 to achieve the same timings as the 1.65 volts of ram. Good luck. An XMP profile allows you to overclock that 1.5 set to 1.65 with an increase in speed. Mixing memory is not a smart idea in that aspect, and you did it with different companies to boot. This is something I would not personally do.



@ the OP if the second kit was at 2133 I would tell you to pick it up and change the timings and voltage to match the kit you already have. Otherwise it can be a crapshoot and you may get lucky, you may not.

- First, sorry for misquote, was trying multi quotes, and it got messed up. Fixed.
- Second, yes, you can achieve the same speeds and timings at 1.65v than you can at 1.5v, because it needs 1.5v, it can handle 1.65, I'm not trying to get more speed/timings out of what I would already get at 1.5.
- Third, your "good luck" seems rather sarcastic. Did you read the thread I linked way above? I've already done it on a Gen1 core i7 920, can't do it on a Sandy Bridge i5 though. Check the thread.
- Fourth, XMP isn't just that.... See pic. See: 1.5v for XMP.


- Finally, and ironically, my sucess was with different companies (OCZ and GSkill), yet I'm failing with 4 sticks of Corsairs all rated at 1600mhz, and clock 9, and 1.5v, the only difference in the 4 sticks is that 2 are marketed as "pro".

Thoughts now?

from my years of doing this yes the voltage needs to be the same. I have set 1.5v ram sticks to 1.6v to match, but as others have said you can't set a 1.6v to 1.5v it works sometimes but it will not be stable.

and zemco is correct. it is best to run matching ram, I don't mix ram often but have done it lots of times and have been lucky I guess.
now the systems that I have mixed ram were not overclocked gaming systems, they were just standard application and internet browsing systems.

to the poster having trouble with Corsair ram, I have never had good luck with their ram. power supplies, cases, and mice yes, but not ram.
