Latitude E6510 Owner's Lounge

Hi all,

I booked one E6510 with i7-620m processor, 2GB 1333 memory.

The laptop has not arrived yet, so I have no REAL details regarding the memory specs.

However, I intend to purchase this crucial 8GB memory to upgrade.
Newegg.com - Crucial 8GB (2 x 4GB) 204-Pin DDR3 SO-DIMM DDR3 1333 (PC3 10600) Laptop Memory Model CT2KIT51264BC1339

Then I found this specification page from intel, Intel® Core? i7-620M Processor (4M Cache, 2.66 GHz) with SPEC Code(s) SLBPD, SLBPE, SLBTQ. It indicates that i7-620m ONLY support memory up to DDR3 1066?!

So my question is :
1, Can I buy the 8GB DDR3 1333 204pin PC3 10600 laptop memory to upgrade?

2, Does anyone have done so (on his/her own laptop, manually) before and proved working?

Thank you very much

 

I have not done this with this system (as I don't have it), but what will happen is simple. The RAM will down-clock to 1066MHz, simple as that.
It's rare that the memory becomes unstable in such situation. If theri is a problem, it's usually the motherboard not liking the memory, which is detectable at first run (won't startup properly or at all), or you'll get a 'memory management' error BSOD during a stress testing.

Be sure that you have Windows 7 64-bit to enjoy your RAM, and the full potential (power and features) of your new computer.

Check out G.SKILL (a good memory brand, aims at gaming system and workstations): http://www.newegg.com/Product/Product.aspx?Item=N82E16820231294
It's cheaper, the right speed (as the other one won't provide you with better performance), 1.5V, and lower latency.

 

THank you GoodBytes!

Yes I also considered the possibility that 1333 will be "under performed". Then why does dell still equip it with 1333 memory even when I choose i7-620? strange.... Maybe their memory is just too cheap....

As for G.SKILL, I thought people commend that crucial performs better than G.skill? I usually trust kingston more in the past. However this time I cannot find suitable kingston memory sets for E6510...

And yes I use 64 bit Win7 thanks.

 

It could be that Dell order A LOT of 1 kind of memory for several systems, as they work, they have no need to get something different. So they save more money, even though at an individual level, it would cost more to get the faster memory. The more you order, the cheaper it is, per individual unit.

They are all good brands. RAM doesn't have hidden performance. At a technical level, it IS possible, but that is mainly to the motherboard doing some workarounds (by design) to support a certain RAM (usually low end motherboards). Performance degradation is minimal and won't be visible on a laptop (you'll have other thing bottle-necking the system, before reaching the max memory performance to have this reduction in performance).

 

Thank you goodbytes!

 

I would add that when the RAM downclocks to a lower frequency then the latency (the number of clock pulses to do the various memory access functions) also drops, so the actual performance hit is very small. The various timing settings can be inspected on the SPD page of CPU-z.

if anyone has an SD card, I would really appreciate some help testing something. I need to confirm whether there is a driver problem, software problem, or hardware problem with my setup.

I have a canon camera, with a 16GB card in it. to use the modified canon firmware, i have to dual-partition the SD card (with a 2-16mb partition, and one in fat32 of the remainder). On my e6500, I use Sdminst.exe, which i am attaching. it is completely reversible, but it allows you to put two partitions on the SD card and switch between them. however, with the default windows 7 driver, i cannot switch partitions (the button doesnt show up), and with the latest ricoh drivers on the dell site, if i put a two partition SD card into the reader, it tells me windows needs to format it before reading it (which is clearly wrong) -- the SD card formatting works fine for both of my other computers.

anyone willing to help test, i would appreciate it.

 

Both versions are dell drivers downloaded from dell, so be warned if you use display port audio!

 

I have the WD6400BEVT in my E6510 and don't notice anything unusual with the fans.

I prefer the WD drive over the original Seagate Momentus 500GB 7200rpm that came with the system - I found the constant seek noises on that drive to be somewhat annoying.

 

I should be joining the E6510 "club" when mine arrives on Thursday (ordered today from the outlet store).

I am cheap, so I waited the a few months so I could pick one from the outlet and use a 20% coupon. This will be the 4th outlet computer I've purchased from them, and I haven't seen as much as a scratch on any of them. I added on the $99 for 3 year next day service, so I'm not concerned about any repair problems.

Price: $911 before tax and 3 year warranty (free shipping)
Basic stats:

-- Processor: Intel Core i7-620M Processor (4M Cache, 2.66 GHz)
-- 512MB NVIDIA NVS 3100M
-- Genuine Windows 7 Professional
-- 8X DVD ROM Drive
-- 15.6 inch UltraSharp FHD(1920x1080) Wide View Anti-Glare LED
-- 320 GB SATA Hard Drive (5400 RPM)
--- 6 Cell Primary Battery, 60W
-- 8 GB DDR3 SDRAM 1066MHz (2 DIMMs)
-- Slate Silver

It was the most expensive E6510 on the outlet, but I think it's a pretty good price considering the 8GB and all.

I've been limping along with a 3 year old Asus G1 which has the best screen ever, so hoping for the best, because I tend to be picky with screens.

My only question is how is the underside for comfort on the lap? I do use a laptop as a laptop. The Asus has some sharp plastic feet on the bottom which I could live without.
