question about upgrade RAM

hi,

Can anyone let me know if these RAM will work on M11x R1? thinking of upgrading my unit to 8GB.

DDR3-1333 PC3 10600 SODIMM 4GB Notebook Ram Samsungchip - eBay (item 270570223248 end time Jul-25-10 19:43:58 PDT)

or these

thanks

 

cheaper here i think.

Newegg.com - Computer Hardware,Memory,Laptop Memory,4GB

 

thanks.. unfortunately i live in Canada and those price are not available on Newegg.ca

 

I'd prefer to go with a popular brand if you want to try it out, and best buy it from a place you can return it if it doesn't work.

Check this out, I'm thinking of getting these babies:

Canada Computers - Mushkin Essentials 8GB (2x4GB) DDR3 1066MHz CL7 SODIMM (996644)

Good price for us Canucks

 

That is a good price. Looks like DDR3 prices are falling a bit. I paid $240 and now its $215 ish.
This is the kit I got:
Newegg.com - G.SKILL 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1333 (PC3 10600) Laptop Memory Model F3-10600CL9D-8GBSQ

 

Considering that we're stuck at 800 anyway, I wonder if I'd go with the Gskill (CL9-9-9-24) or the Mushkin's (CL7-7-7-20)...

 

@All - the ram that came in my R1 is 6-6-6-15 ... isnt lower better? Has anyone tried a few different speeds to see what the benefits are?

Best Wishes, StevenX

 

@stevenxowens792, you're right, CAS latency is generally better when lower, but a higher CAS latency at a much higher memory speed (ie: 1333) will still be better than a lower CAS latency at a lower speed (ie: 800).

Problem is choosing between to different RAM with different CL's at marginally close speeds (1333 vs 1066). For example (taken from Wikipedia):

DDR3-1333 CL9 has a first word latency of 13.5 ns while
DDR3-1066 CL7 has a first word latency of 13.13 ns which could make it quicker on paper...

Our problem is worsened by the fact that we're stuck at 800...

But really, can we see the difference in normal use...?

 

man i wish we had settings in the bios for memory manipulation.

 

Stuck at 800?
Does this not increase when we OC the CPU? CPU-Z seems to say so.

Not as good as being able to up the memory on its own but certainly pushing closer to 1066.

 

That's what a lot of people are saying (apparently a limit of the ULV), perhaps (and hopefully) I'm wrong too.

 

I dont believe the memory gets faster than 800 regardless of oc or not. I do know that memset (i will have to get in front of my m11x for the real name) allows us to change the latency. My mem will only allow 65512 (or something close to that)... made very little difference in 3dmark if I remember correctly... However if someone can show a 2-3 fps improvement in a game based on going from 6-6-6-15 to say 4-4-4-12 or 3-3-3-12 I would spend the money right now!

BW,

StevenX

 

I dont see the point of buying 1333+ RAM if the machine only supports 800?

 

nice find Maxgeek.. its also available on newegg.ca for $220 CDN
I will have to read up on it and if I cant find anything else, I will probably order that kit

 

that is a good price...

I live across a canada computer and if I can avoid it, I would prefer not to give them the business... somehow I feel everyone in the store lack customer service skill.. especially the guy at the cashout

 

To the OP: my m11x uses that ram no problems here...

I bought this @ 1333mhz because I got a sweet deal, the same price as 1066mhz...

 

thank you Mexican Snake

 

No problem mate .

wooha 8gb of ram are very helpful for me I couldnt resist the price.

Mabey we should start a petition to have them put in memory settings in the bios so we can tune our RAM. I am a fan of what EVGA does with thier bios. It would be really sweet to have those kind of options.

Although i think they would have to leave out voltage settings. Or mabey put it in so we could under volt.
