Question about RAM upgrade

[Anirith]

Hello. I currently have 8GB DDR3 RAM in my laptop (HP ProBook 4330S), and want to upgrade to 16GB with two sticks (2x8). I can choose between the following:

 

1066MHz - CL7 (7-7-7)

1333MHz - CL9 (9-9-9)

1600MHz - CL11 (11-11-11)

 

Which of the three above mentioned would you go for? My CPU and motherboard support all three. If I understand it correctly, the first one will outperform the two others because of lower latency, right?

[RedWulf]

The first number is the speed, higher is better. The second is the latency, lower is better. These impact performance in different ways and different use cases benefit from each. I'd personally take higher speeds with worse latency from these options.

1600c11 cause freq is king when you have no control over subtimings and the primaries esp cas latency dont mean shit for performance (excl trcd but tuned subs >>> trcd)

 

running over 1600mhz might also be possible as shown here though unsure of any details as i have yet to try it myself on my x230 but it looks to be as simple as editing the spd to run at higher speeds like 2400+ though if your laptop is sandybridge itll be limited to 2133

 

whats the cpu and current rams anyway?

Current CPU is i7-2820QM and RAM is 2x4GB DDR3 1333MHz CL9 running in dual channel.

 

Side note: I can't change any RAM related settings in HP's stripped down BIOS. Plug n play only.

not talking about bios you dont need it for laptop mem oc just need to flash the spd on the ram sticks (via os) and it should just work though ill have to give it a go myself before i can help with that

 

but yeah youll be limited to 2133 if you manage to get it working as sandybridge is stuck to 2133 mem multi

I'm not interested in any flashing, just want to run the RAM modules normally. But based on your first comment in the thread, I will order 16GB of 1600MHz 11-11-11 and not think about this anymore

cheapest you can get is the best you can get cause those branded sticks dont mean jack shit without their xmps

 

theyre like 5$ for used 8gb oem sodimms or "new" fake china 8gb sodimms (black sticks, nonsense partnumber, functionally the same as regular oem sticks)

If you install 1600MHz RAM it will work only on 1333MHz. As I look for specs online your laptop doesn't support higher freq RAM. But if there is no price difference than doesn't matter.

Why not check what RAM shows CPU-Z? Or pull out RAM and check specs.

I've seen others already run 1600 and 1866 with my exact laptop and motherboard, so I know it will work with those speeds. My current memory is 1333MHz 9-9-9. I've already ordered a new set of cheap 2x8GB 1600 11-11-11 from China now.

Good point. I've placed an order for a set of cheap 2x8GB 1600 11-11-11 from China now

If motherboard does support 1600Mhz speed or 1866MHz why not. Good luck with china RAMs. I don't know what brand did you bought but I don't trust china seller. You can buy cheap ram from FB market, ebay, amazon. If is no secret how much you paid for ram?

RAM from Yimeng. 11.16EU for 2x8GB sticks.

Definetly I don't trust Yimeng manufacture RAM. If RAM will be defective then to send back will cost more then buy well known brand.

If you are located in Germany quick search approx EUR 20 cost.

sounds about right for a couple of 8gb sticks these days as pricing has fallen off a cliff and youd be pretty stupid to pay any more than 10€ per stick

Nice review about chinese RAMs.
