Question Bigger RAM sticks or not.

[Transam4558]

After my last question here, my ol' PC is now up and running great, this time with a different CPU, Intel E8500 @ 3.16 GHz, RAM are the same 2 x 4 1333MHz RAM sticks..

My system is an LGA775 1333 O.C. board, yes it is ageing, but I like it.
Been messing around with overclocking the E8500, it has really speeded things up, temperature all round is OK too with the settings I ended up with, below is a list of overclocked CPU-Z info from it, my question will follow.

Core speed..........3750MHz
Bus speed.............394.75MHz
Rated FSB.............1579.01

My question is, as the numbers are way higher than stock, should I replace the RAM sticks with 1600MHz, which will fit, and is near my FSB, or will it not make any difference...?

Thanks in advance....

What is the primary purpose of the PC?

"............make any difference..........."

Changing RAM will surely make a difference.................in some measurement. Perhaps a benchmark.

Is that what you mean?

Or do you mean a noticeable difference in your real world tasks?

Put another way....if you made the change, what would disappoint you? We don't know your hopes or expectations.

If this is all experimentation as a hot-rodder might do with a car, then go for it. You live and learn, trial and error, in conjunction with all the rest of the parts in the hot rod.

Yes, my ol' PC is now my Holley carb, as the hotrod has gone..........😛
I just want to know what will happen with the 1600MHz sticks, it will be something or nothing, do you know....? 😉

It will be something.

You may or may not approve of the something.

Carter AFBs on a short ram manifold are the ticket.

I just want to know what the something will be, in other words, does the "now" Rated FSB of 1579 MHz need 1600MHz sticks to perform at its best, just a yes or no will do.......

I had an 800 Holley on top of a "Doug Nash" Warrior intake for my UK street car, you can't get better than that.....😛

What is exact model name of your motherboard?
You can find it with CPU-Z - motherboard section.

I know it off-by-heart with all my dealings with it....😀

ASUS P5G41T-M LX...Manufactured in 2013....

I must repeat, it is working great, I just want to know that if the FSB is now near 1600MHz, but the board is manufactured as a 1333MHz board, will me installing 1600MHz sticks improve things...

Sorry for the late reply, I am on the other side of the world......

Memory and FSB were generally coupled in that era so I'm guessing your memory is running at the same speed as the FSB. It's worth looking in CPU-Z under memory to see what it's running at as I'd imagine it's the same as your FSB. If that's the case there's no reason to get faster memory since the only benefit you'd get is if your system wasn't stable and memory was to blame.

Just done a CPU-7/ memory, a bit beyond me, but have a look...

DRAM Frequency.....................789.5MHZ
FSB: DRAM.................................1:2
CAS# Latency.................................9 clocks
RAS# to CAS# Delay....................9 clocks
RAS# Precharge............................9 clocks
Cycle Time....................................24 clocks
Row refresh cycle time.........107 clocks
Command Rate.........................2T..

The DRAM is Double Data Rate (DDR) so you multiply the DRAM Frequency by 2 and get the speed your memory is effectively running at: 1579.

Still would like a definitive answer, but perhaps there isn't one........

Motherboard is 1333MHz overclock-able.....
Now overclocked the Intel E8500 to 3.75 MHz, works great.
But the MHz is now 1580MHz with the original 1333MHz RAM sticks.

Will the set-up be happier with 1600MHz RAM sticks.......? 😛

No, and the question was already answered:

CPU-Z says running at 1580MHz, I think that is perhaps the motherboard O.C. limit, as I used that in experimenting, I just thought that IF 1600MHz sticks were installed it may improve stuff if on auto.... Think I will put it on auto and check the MHz after.

Thanks for reply...😉

 

[Transam4558]

Did an MHz test on auto and checked on CPU-Z, still at around 1580MHz, but the CPU (now at idle/CPU-Z) is jumping from around 2.34 to 3.75, temperature is now lower too. Hmmmmm, and still runs great. 😊

For a bit of fun, I might buy a couple of 1600MHz sticks, just to see what happens, will post back.....😛
