OCZ RAM in a T61

[Tholek]

I was looking at a 2GB stick from OCZ (OCZ2MV6672) and wondered if it was quality enough.

EDIT: My apologies for the original n00b question. I should've googled better.

OCZ makes all types of memory, from laptop to high end professional desktop. I have a 1GB stick in my laptop, along with an IBM supplied stick. It works fine. Also, if you install a 2GB stick alongside a 1GB stick, the laptop should not attempt to go dual channel, which will keep you from having the incompatabilities that occur with certain combinations of 1GB sticks.

I have a 4gb kit from OCZ that I believe contains two OCZ2MV6672s, they are good. Tried one of them with a 1GB stick supplied by Lenovo and they work at a half-assed (async) dual channel mode, which I don't really care because the FSB is only 677 anyway.

[Edit] Sorry my bad didn't notice you are using T61. In that case you'd better get 2 of them for the sake of dual channeling. With a vista-64 you wouldn't wast any memory.

I hadn't expected to spend so much. I see it for $85, but 2 will really hurt me financially. I've got a minimum 512MB stick coming, and hoped 2512MB would do on Vista. Doesn't the T61 only recognize 3GB anyhow? Also, don't they have to be a matched pair if you go with two sticks? If I buy two individually, is that the same? I thought not.

$85? Eh? I spent $300 for the pair I got, that's something called Canada hi-tech tax I guess... Yes it really hurts, especially that I'm only getting 3GB sharp.

Yes 2.5GB would do well on Vista as long as you don't plan to run virtual machines or development suites. The only issue is RAM speed, because if I'm not mistaken T61 has 800MHZ fsb, but then again it's nothing compared to the performance gain you are getting through added memory.

I believe T61 supports full 4GB as long as you use vista-64bit. Otherwise yes 3GB.

As for your last question, my personal belief is that when you buy one later the two will still pair up. If the specs of the two are different, the pair will run as the worse of the two.

Hope this helps.

I believe the Santa Rosa platform is the first to support more than 3GB in hardware. The limitation is a software and hardware limitation. Once you move to the newer laptops, it becomes a purely software limitation.

Well, that extra $85 will still hurt me. If you have any free sticks of compatible RAM, be sure and let me know.

I'm gonna guess that extra 512MB wouldn't make that much of a difference, even in that situation. As for 800Mhz RAM, I've seen conflicting reports as to whether or not it's better. I guess it's a moot topic anyhow, because it isn't as cheap.

Goes without saying, since I don't see a 64-bit option on the lenovo T61 cofigurator. That's why I mentioned 3GB. The max is 4GB on this even with 64-bit. I'll never top that.

Yeah, like downclocking, but will TWO of the same model sold separately be the same as a "matched pair" sold as such? I thought they could only work as well when sold that way.

Sure, I'm talking about that 2GB stick you are adding! If you used to have 1GB (512*2) you are running dual channel, and your memory bandwidth = 667*2=1333MHZ > 800MHZ FSB. Now, whether you are getting 2GB+512MB or 2GB alone you get 677MHZ < 800.

Here's what I believe: kits are created as a convenience so that you don't have to worry about different timing/latency between the sticks. If you buy one today and another one of the same model tommorrow, there's extremely unlikely that you get into any trouble.

I ordered mine with a 512mb stick and installed a 2gb stick along with the 512mb when i got my machine. It works fine in Vista with ~2.5GBs.

Hmm, some new questions...

If I did have a matched pair of 2GB sticks, Would it still run in dual channel, despite only having 3GB available?

Will running them in dual channel mode have that noticeable an impact on performance for me?

More so than 2.5GB not running in dual channel?

How about 2.5GB non-dual channel vs. 2x1GB sticks running in dual channel mode? What's better there?

Thanks.

From doing a little research before purchasing the 2gb 1 dimm stick of ram, i asked myself the same question- would there be a noticeable difference if i were to run 1gbx2dimm in symmetrical dual channel versus running 2gb in one dimm and 512mb in the second dimm in asymmetrical dual channel?

The overwhelming answer i got back was no.

[Tholek]

Thanks. Still, will 2x2GB run dual channel despite having 3GB available?
