800mhz vs 1600mhz ram

[shivam02]

is there any noticeable fps difference while playing games like watch dogs on 8 gb 800mhz and 1600mhz ram?

Take a look here..
I don't see 800 mhz there but it might help.

i am sorry but i didnt get much of it.
could you please sum it up and tell me in yes and no.

Depending on what sticks these are they may both be 1600 - DDR3 (DOUBLE data rate 3) is normally designated by the effective rate (say 1600) when the true freq of the sticks is 800 (take true (800) x 2 to get effective (1600)), If you look in CPU-Z it shows true freq....What are the model #s of sticks you are looking at?

Am guessing that's the case here, though DDR 800 PC3-6400 exist, you seldom ever see any

From what I understand there is no real reason to buy anything more than 1600 MHz
only if you use an Integrated gpu there is reason,

I move from 800 MHz to 1333 MHz but i also switch my CPU so i don't know if the ram made such a difference,
I'll tell you this 1600 MHz is better i don't know by how much, and it's mostly cheaper..

can i overclock my ram?

 

[adamdbz]

It depends on what CPU you are using, While i did OC my old CPU and I still OC my graphics card I never OCed Ram.

https://www.youtube.com/watch?v=dWgzA2C61z4 ...as this video goes to show, ramspeeds and CAS latencies dont really make that much of a difference, although there are some games out there that are starting to take advantage of that high speed mhz......i would still go with the higher speed rams considering that 8GB requirement is going to be the norm for a considerable amount of time and getting higher speed ram is better in terms of keeping up to date with technology

have a look at this as well http://www.tomshardware.com/reviews/memory-bandwidth-latency-gaming,3409-4.html as this shows, some games like F1 2012 indeed DO BENEFIT from higher ramspeeds and lower CAS latencies ...plus there really isnt much of a price difference between high and low speed rams, i always go for 2133mhz with CAS 9 or below....something along the lines of these are my favourite

Leonell12 is right Linus knows hes stuff..

 

[Tradesman1]

Sure if mobo, CPU and DRAM itself can support it

 

[Leonell12]

That is indeed true Tradesman1...most gaming oriented motherboards can support upto 3200mhz OC* and even though intel cpu's reportedly have issues with voltages above 1.5v ...the XMP profile really eliminates this problem, i would advise the OP to check if their motherboard supports high-speed ram, and also probably just opt for voltages that comply with intel cpu specifications just to be on the safe side

 

[adamdbz]

If he has 800 MHz ram he is probably running a cure 2 duo.

______________________

The 1.5 suggestion is made by Intel based on the 1600 recommended sticks, Intel has been certifying DRAM at 1.65 in higher freqs for quite awhile now...there's no danger through 1.65....and keep in mind it's all well and good that the mobo can support the high freqs, but these days it's more the CPU and specifically the MC (memory controller) in the CPU that determines the actual freqs you can run, with Intel for the most part to run 2133 and up requires a K model CPU

haha i dont know about that man...my friend's rig is running with a i5-2500k with 2x4gb 800mhz ram that was salvaged from an old HP computer...works fine!

btw, shivam02 it would be very helpful if you could provide us with some more details on the rest of your hardware

 

[shivam02]

i have fx 6300 and gtx 750ti .
and my mobo supports up to 1600mhz.

 

[Leonell12]

ok thanks...every motherboard supports upto 1600mhz officially but everyone of them also support a XMP profile...some upto 2400mhz oc* others upto 3200mhz oc* and above....can we have your motherboard name and model?

 

[Tradesman1]

What are your DRAM model #s, will make this whole thing a lot easier

its the cheapest mobo you can get

[Leonell12]

right ok well your motherboard requires an updated bios to support amd fx series processors, i'm assuming you've already dont that so anyways according to Gigabyte's website, and contradictory to the website you linked, your motherboard has native support upto 1333mhz ramspeed, however higher ramspeeds are not a problem if the XMP OC profile is enabled...so i think you should be fine with the ram sticks i linked earlier

what is XMP OC profile and how to enable it if its not

 

[Leonell12]

this is what gigabyte's website says regarding memory ''Support for 1333+ (O.C.)/1066 MHz memory modules''...XMP profile allows memory of higher speeds to run on a motherboard that does not officially support them.....you need to enable it in the BIOS, however you should have a look at your motherboard manual and see what that has to say about the matter as well

EDIT: these are the memory sticks your motherboard supports, http://www.gigabyte.com/products/product-page.aspx?pid=4311#memory%20support%20list ....it says '(downgrade to 1866mhz)' so i'm assuming even if you put in DDR3 2133mhz ram, it will only run at 1866mhz, i'm not sure if that is after enabling XMP or before though...as said earlier, your motherboard manual should be your best friend at this point

I made an account just to say thank you
