Cheap 16GB RAM alert (again)

That about half the price I paid for my 8GB kit. Any idea if 16GB would work in a mid-2009 MBP?
 
just FYI everyone, the corsair value select ram kit seems to be hit or miss with Macs. Mine ended up causing 4 kernel panics in 3 days and I returned it within an hour of the 4th. The guy at Fry's even mentioned that this kit performs inconsistently with Macs. You get what you pay for.

My pair has run the last 48 hours like a champ. Had some free hours earlier so I started Rember and ran 4 cycles. All of them passed. Didn't have time to do more, but the 5th cycle seemed okay as well.

Type this in a Terminal-window to get your CPU name:
sysctl -n machdep.cpu.brand_string
Click to expand...

Then search on Google for the CPU name and add this search string to your query:
ark.intel.com
Click to expand...

This is an example (Click me!)!

That gives you the data sheet for your CPU, and tells you how much RAM you can use in your machine.
 
Just picked up the same Corsair 16GB pair.. definitely runs a LOT hotter than the Samsung 8GB PC12800 (1600) 30nm pair I pulled out.

Also, Xbench is showing the corsair DIMMs about 10% slower than the Samsung 1600's...

Definitely concerned re: the heat generated running Rember..

I've got the bottom off and the DIMM's are so hot you can't touch 'em.

Anyone else getting this kind of heat running memory test?

I didn't take the bottom off and felt the RAM directly (because I feared I might short it), but my fans didn't go any louder while Rember was running.

And in my general use, the bottom has never gotten noticeably hotter or anything out of place. But that might just be me.

The package did seem... dodgy, and I did get the impression that it was "cheap for a reason", but so far, it has been reasonably good, and the performance boost is something I can't deny... being that I rarely restart my Mac (perhaps once a week or after a critical update, whichever is more frequent).
 
Tempting upgrade but I can't imagine how I would notice any benefit with my typical applications and my current 8GB of 1333 Mhz Ram: Aperture, DeltaGraph, JMP, R, Word, Excel, Powerpoint, Papers2, Safari, iTunes, etc. Only Aperture seems really Ram hungry. When seriously editing I just close the other apps.

I attached a thermocouple temperature probe to the DIMMS and towards the end of REMBER, they get to at least 170 degrees.. that seems really hot!

Do you happen to recall what chips were on your SODIMM modules? Mine are Corsair branded dram chips, but I'll bet they are made by a 3rd party and branded for Corsair.

They are just as I posted them earlier in the packaging. I think it's the same RAM you bought.

So now, when will we see 32GB? :D

i agree it will happen eventually, probably soon. There are quite a few enterprise grade systems, mainly blade servers, that use so-dimm (laptop sized) ram. ANd big buisness is what drives technology, People may only think of consumer level products and thats where companies make money, but when a single workstation costs 6k, and companies buy dozens-hundreds at a time, thats money.

These will surely drive to larger memory in single dimms, especially since virtualization is becoming commonplace. I worked at a big tech company and it turns out the majority of computers will be virtualized by 2020... of course this is speculation... but it definitely seems believable

EDIT: most people only focus on cpus and gpus growing, greater density and smaller silicon processes, but hey if AMD can make 28nm features, why can't memory makers?

Where in Europe did you order as I wouldn't mind ordering this from the UK - Do Frys ship to the UK? :rolleyes:
Click to expand...

I ordered form denmark, and as far as I could tell, they ship basically anywhere.
however I'm having it shipped to a factory in the US where I'm having a co-worker pick it up, that way I can avoid customs.

So that's something to consider, getting caught in postage customs might just make it cheaper to buy in the UK.

edit: just shipped

Within the specification. I think such components can reach up to 135 °C (or 275 °F).

From
http://www.hardwaresecrets.com/article/Corsair-Factory-Tour-in-Fremont-CA-USA/166

We visited Corsair memory factory located in Fremont, California, where they manufacture their high-end memory (XMS series) and server modules. Corsair also has a factory in Taiwan, where their entry-level modules (Value series) are manufactured.

I'm curious to see how low 16gb is going to drop in the near future. Seems to be plummeting...

I just ordered this same kit from newegg this morning for 160ish. Nice savings with this deal, but I have had great luck with newegg and think i'll keep my business with them.
 
The deal has expired. RAM sticks are back up to $69.99 per single stick.
 
Just put it in and it's been working fine.

Ran Rember for about a day and no errors at all. It was 13 passes or so.

Also ran TechTool Pro 6's memory test, no errors.



Quick question, though. Does more ram= more battery power?
