Question about RAM

[n0cturnal]

So can I get 1600hz or do I have to go for 1300hz?

You can get 1600MHz but if you use it combined with your current 1333MHz they will all run at 1333MHz.

Legend! I dont mind buying 2 new sticks

After reading the manual from my motherboard it says..

'Memory = Dual Channel DDR3 Memory Technology
2 x DDR3 DIMM slots
Supports DDR33 1333/1066 non-ECC, un-buffered memory
Max. Capacity of system memory: 16GB'

So if i'm right... ' http://www.scan.co.uk/products/8gb-(...-9-9-9-24-150v ' should be fine?[COLOR="red"]

So http://www.scan.co.uk/products/4gb-c...-9-9-9-24-150v it is then!

Edit: i asked my step bro and he said summin along the lines of 'it looks like they won't work in parallel''....??

What he is talking about is Dual Channel. In order to run in DC, both memory modules have to be able to run at the same speed with the same timings. That can be tricky when you have 2 different modules, which is why MB manufacturers usually tell you to run identical ram in all of the memory slots.



Here is the same ram from Overclockers. Looks to be a bit cheaper:

Yeah thanks.... got those exact ones!

So i successfully installed my new 8gb 1333mhz RAM. This is what speccy is saying its like now....

Memory slots
Total memory slots 2
Used memory slots 2
Free memory slots 0
Memory
Type DDR3
Size 8192 MBytes
Channels # Dual
DRAM Frequency 665.9 MHz
CAS# Latency (CL) 9 clocks
RAS# to CAS# Delay (tRCD) 9 clocks
RAS# Precharge (tRP) 9 clocks
Cycle Time (tRAS) 24 clocks
Command Rate (CR)

Is this all correct? 665.9mhz? or is that multiplied by 2?

[n0cturnal]

Yes it looks correct. DDR = Double Data Rate it is always reported at half the speed.

Thanks man!

Crucial has a memory scanner tool on their site. And you can buy the RAM directly from them at along the same cost as newegg. They have a compatibility guarantee. My motherboard was dated so I had to flash it so it would accept the 8 gigs (would only post with 4 gigs) but you shouldn't have that problem.

You did good on the purchase, the XMS3 sticks are very well rounded ram at reasonable prices. I've got an 8gb kit in my server and I've never had an issue.

It's not the motherboard which decides, it's the IMC if it can handle. He has a sandy bridge so this chip handles easily 1600MHz and voltage is just complety botherless because the motherboard will always set the DRAM voltage as default to 1.5V with any 1.35V modules before you load an XMP profile or setting it manually.

@OP Try this set.. It's only 40 pond -> http://www.scan.co.uk/products/8gb-(...9-9-24-xmp-15v

And is 267MHz faster so.

Sort've. The motherboard decides if it supports overclocked ram. The IMC decides what is overclocked. Anything higher than 1333mhz on Sandy Bridge processors is considered overclocked. Ivy bridge supports 1600mhz default, anything over is considered an overclock.
