I have 8gb of XMS3 - IS this okay for Sandybridge?

[Metalface Mark]

Im considering upgrading my i5 @ 4ghz bundle for a a 2500k or 2600k setup, would i still be able to use the same ram or would this need changing as well?

If I went for the i7, would i need to only use 6gb to get the best benefit for triple channel?

Triple channel is only on the X58 i7s, not the newer P67

Your existing dual channel ram should be fine in a sandy bridge board. Just check what the operating voltage ranges are for your modules - as you should be running memory at ~1.55V with a SB system, compared to 1.65V for nahalem.

Great, thanks for the advice.

if you went i7 mind, you could always chuck in another 4gb and have 12gb to play with..

Like others have said, you don't need triple channel for P67, only for X58. So in that way, your RAM will be fine.

But I imagine that it is 1.65v RAM if you're using it with an i5-7x0, and I have heard that there are problems when using 1.65v RAM with P67 - I know some people have had problems getting the motherboard to recognize their 1.65v XMS3 properly.

Dont you mean triple channel

I do, thanks for pointing it out

Is it really an issue having non 1.5v RAM?

I have bought 8GB of XMS3 (1.6v-1.65v rated) and am wondering if this will be an issue on my i5 2500k and MSI P67a-G45 now :S I got it because it's the only RAM I could see that would have height clearance due to the Zalman cpu cooler!

i've got 8GB XMS rated 1.6v - 1.65v and i've had no issues once I enabled XMPP in bios (to stop a double cold boot issues prone to all P67 boards).

Ah I just checked the Corsair website: http://www.corsair.com/memory/xms-classic/xms3-ddr3-memory/cmx4gx3m2a1600c9.html

The modules do support 1.5v @ SPD but Corsair test them at 1.65v and so the store advertises them as such.

Happy days :d

Edit*

But the SPD voltage seems to be at 1333MHz....hmmm!

f00f1ght0r yours are at 1600 yep?


Edit*
And according to Corsair it should be compatible: http://www2.corsair.com/configurator/product_results.aspx?id=1872981 (model CMX4GX3M2A1600C9)

I've got the same set in my p67 and it's fine.

Went into the bios, changed settings to 1.5v, 1600MHz, set timings at 9-9-9-24 and that was it.

No issues at all.

 

[mrk]

Excellent thanks

I assume no funny business before setting the profile? Other than the dual boot from cold issue which the P45 has had before too.

 

[Steves1982]

No, absolutely fine. 1st time boot into the bios and away.

Not sure about the cold boot issue as I changed the settings straight away and didn't notice it on the 1st boot.

What sort of issue?

 

[mrk]

It double boots, Intel chippy mobos have done this for some time where you cold boot, it turns off before POST then a few seconds later it boots up normally. I think people called it the infamous "Double Boot".

My Gigabyte UD3P did this

Same here..

Memory is in, 1600MHz, 1.5v, super stuff
