Mixing ram modules?

post #1 of 8
Thread Starter 
Would I be able to drop the voltage to 1.5, raise the timings to 8-8-8-24 and drop the speed to 1066 (PC3 8500) ? On these http://www.ocztechnology.com/ocz-ddr3-pc3-10666-platinum-low-voltage-dual-channel.html ?

Using atm
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231445

on my ASRock z75 sandy bride system with a i3-2100.

If I would be able to do the above, can I mix both ram sets together if I bring the OCZ's on par as to settings with the gskill ripjawx?

Yes, you can. Keep in mind, though, that by doing that you might actually make your system slower than with 8Gb.

Because the GSkill RAM is 1.65v, you can either:

A. Try to get it down to 1.5v by lowering the frequency/loosining the timings/etc.
B. Keep the voltage at 1.65 and run both sets at 1333. You might have to loosen the timings a little for the GSkill stuff.

Really, I would reccomend that you either buy the same RAM you had before or replace the GSkill stuff with more of the OCZ stuff.

The gskill is 1.5v, the ocz is 1.65

OCZ would be the needing to loosen the timings. OCZ is 7-7-7-20, gskill is 8-8-8-24.

I understand that matching ram is best but for a free 4 gig set, cant hurt to try.

I heard something long ago about using any ram over 1.5v can destroy a sandy bridge system. Is this true?

Did I get it mixed up? Sorry about that, I'm not feelen too good today tongue.gif


About running ram at 1.65v:

There has been debate about this issue ever sence Sandy Bridge came out. There are those who insist that it will ruin the memory controller and there are some who just dont care.

I belong in the second catagory: Ive been running Mushkin 1.65v 2133 RAM for about 1 and a half years now with no adverse effects.

K, I will give it a go some time soon.

Thanks for all.

Got'em installed.

I had to pull the OCZ's out, go in uefi and manually set 1.5v for dram, as with the ocz's installed, the lowest it would go was 1.58v. I had set it at 1.5 from auto, shutdown and pop back in, the ocz's.

Both ocz sticks are running at the gskill's specs. 800mhz, 8-8-8-24 t1, 1.5v, 1066. Not bad for free. Now I'm upto 12288 MB.

All seems well atm. No hiccups.

I had to pull'em. They became problematic. App crashes & then system crash.

Uh well, worth a shot. I'll prob sell em off somewhere.

Thanks for your time, Alfaa.

I figured you might have problems redface.gif

One last thing to try, though:

If you were getting app crashes and stuff while running the OCZs at GSkill spec, try to lower the frequency/loosen the timings even more. Also, instead of going in Windows to try it out try using memtest for testing stability. Because RAM might be Windows stable, but as soon as you run somthing memory intensive (like a game) it causes problems.
