Dell Precision 5510 Owner's Lounge

Intel Ark shows the max speed for this generation of CPUs as 2133 MHz. Higher speed memory might work (I don't recall at this point) but I wouldn't expect anything higher than 2400 to work. (You can install faster memory and it will run at a lower speed.) When you take CAS latency into account, running memory with a higher MHz rating doesn't actually help much and certainly won't make a noticeable difference.

You can check the make/model of your currently installed memory using CPU-Z (free download). If you are going to buy more memory to pair with your existing memory, it doesn't make any difference whether or not it is the same brand, but it should have both the same speed and CAS latency (CL). You can also check that using CPU-Z.

 

thankyou

any recommendations as to if any make/model are the best in the 2133 category or are they going to much of a muchness?

also i currenly have two sticks of 8, if i just buy 1@16,no problems in running 24?

 

Just did a search and this one came up with good reviews.

CL 15
1x 16GB https://www.newegg.com/Product/Product.aspx?Item=9SIAG7R7ZV8895
2x 16GB https://www.newegg.com/Product/Product.aspx?Item=9SIACVB57X3023

These don't have many reviews but Hyper-X is typically good.

CL 13
1x 16GB https://www.newegg.com/Product/Product.aspx?Item=9SIA8N25Z22057
2x 16GB https://www.newegg.com/Product/Product.aspx?Item=9SIACVB7CH8758

You should be able to mix an 8GB and 16GB module but again they need to match both speed and CAS latency. Check the CAS latency in CPU-Z. You can filter based on this value in Newegg and find compatible modules and reviews on them (even if you don't have to end up buying from Newegg). Go to the laptop memory section and set up filters based on speed, capacity, and CL from the options on the left.

 

Dell uses several sources of RAM. You can check what is already installed using CPU-z (Memory and SPD tabs give the RAM info). I don't know if RAM faster than 2133 MHz will work in the 5510 but any increase in the headline speed is usually reduced by longer timings (bigger numbers for the latency).

8GB + 16GB will work and will running in asymettrical dual channel. The first 16GB of RAM will run as dual channel with the balance as single channel (which is slower, but still much faster than page file access on a storage drive). Any new module does not have to be the same type as the existing but ideally should have similar timings. The BIOS checks the SPD data on boot and selects the fastest times supported by both RAM modules and the system hardware.

They don't absolutely need to match these days, the processor can generally cope and sets the lowest common denominator on any shared buses. It's a good practice though and certainly if you're buying a pair of dimms why the heck wouldn't you have it match?

ive been checking prices and im finding the following for 32gb:

cl13 - £350
cl14 - £300
cl15 - £250

i am right in thinking price/performance ratio just go for the 15, am i really gonig to notice any real world differences in everyday usage between the three latencys?

 

Nope.

 

Tried Dell 2666 stock ram. Worked with a 5510 i7 6820.

 

But what speed was it running at? The SPD data on the RAM modules usually contain timings for a range of frequencies at and below the rated speed. Here's what HWiNFO reports for my 2133MHz RAM (CPU-z only lists the highest four speeds):

Supported Module Timing at 1066.1 MHz: 15-15-15-36
Supported Module Timing at 1000.0 MHz: 14-14-14-33
Supported Module Timing at 933.3 MHz: 13-13-13-31
Supported Module Timing at 866.7 MHz: 12-12-12-29
Supported Module Timing at 800.0 MHz: 11-11-11-27
Supported Module Timing at 733.3 MHz: 11-11-11-25
Supported Module Timing at 666.7 MHz: 10-10-10-22

ok hoping to add a m2. ssd to the 2.5" already there. just want to make sure i do this correcly,never done it before.

1. install new ssd
2. reboot, new ssd shows as additional storage.
3. run program such as macrium or samsung migration tool
4.once old ssd has been cloned on new ssd go to bios and change boot drive to new ssd.
5 reboot,should now reboot with new drive
6.format old ssd
