I have ordered a Dell with A C2D 2.83 FSB 1333MHz, Howerver the RAM supplied is only 667MHz.

Q1) If I can upgrade to 1333MHz RAM will my system be noticeably quicker?

Q2) Does the motherboard on the Dell 530 support 1333MHz RAM?

I cant seem to find out if it does or not. Dell were no help when I emailed the question, the answer I got was ' The system is supplied with DDR2 PC-5300 667MHz SDRAM' This I know, but that was not my question.

If you upgrade your RAM then when you are running programs it will load up quicker - so yeh there may be a difference - depending on how many applications/programs you run at once,

A1) Yes, more RAM will make it quicker, not always enough for you to notice mind.
A2) As you said, memory is DDR2. 1333mhz memory is DDR3 so you will not be compatible

If i wrong, apologies but i don't think i am
Link to the pc you have bought might help in gaining an answer; don't fancy delving thru Dell's site, i get bored on there

Does your computer run fast enough to notice the difference with the speed of the memory? The 667 or 1333MHz speeds show the 'potential' speed rather than what your system is actually running it at I think.

Whatever the circumstances you have ordered something and been supplied something different so ask for what you initially ordered from Dell.

Editted to add:

More MHz means faster whereas more MB means more capacity IMO.

The memory is probably in a dual channel set up, so it's effectively 2 x 667Mhz.

Best you can probably upgrade to is DDR 2 800.
Not really worth the bother with systems with crippled bioses.

More ram yes, faster ram, no.

My quad performs perfectly well running 100% on all 4 cores with only 2 gb of DD2 667.

Even if DDR3 is compatible with the board the bandwidth would be wasted as the Dells can't be ramped up.

Surely the FSB 1333Mhz quoted in the OP refers to the CPU's speed.
Example, i am running a 2.2Ghz (2200Mhz) processor
I think things are getting confused here, and like i say a link to the Dell system on the site would help clear this up

Unless one is doing serious overclocking (With a Dell...I don't think so) DDR 2 800 is more than adequate IMHO.

Also, these new DDR 3 modules have very loose timings IIRC.

Quicker? Not unless you want to overclock the system.

The CPU is actually running at a 333MHz bus speed x 8.5 multiplier giving the 2.83GHz stock rating.

The RAM runs at the same 333MHz bus x 2 (as it's DDR2) x 1 (memory multiplier) = 666MHz so the DDR2-667 supplied is just adequate but leaves no margin for overclocking, DDR2-800 would allow you to raise the bus speed to 400MHz, causing the CPU to run at 3.4GHz (cooling permitting) though I'm not sure how versatile the Dell BIOS is on the lower models or how good the stock cooling.

With faster memory you can also raise the memory multiplier over 1 (synchronous) to run the memory asynchronously at nearer to its rated speed (eg, using DDR2-800 on that system, 333MHz x 2 x 1.2 multiplier= 800MHz) but this has only a small benefit in real-world applications.

No, this is nothing to do with dual channel - the 2x667Mhz effective data rate is due the ram being DDR (Double Data Rate), a DDR2-667Mhz module running in single channel still has a 1333Mhz effective clockspeed. Running in a dual channel configuration doubles the amount of memory bandwidth, around 5.3Gb/s for DDR2-667 and 10.6G/s for dual channel mode.

I agree with the poster above, leave the memory as is unless you're overclocking which you probably won't be able to do on that system anyway. If you are running out of ram then obviously adding more will speed up your system noticeably.

Shouldn't need an upgrade at all but if you really wat to, more ram (same) would be more use than faster ram.

But really, see how you get on as is first because I doubt you'll need do anything.

The FSB is the connection between the CPU and the rest of the system, it has it's own clock that's seperate from the CPU's clock.

Not quite correct, DDR2-667 actually runs at 333Mhz and it's equivelent to 667Mhz because of the double data rate (i.e. it's a marketing lie so those who don't wish to understand the technology know it's faster). I said dual-channel was like 2x667Mhz since that doubles the bandwidth again over two sticks of DDR2 667 in single channel mode.

cpemma explains it better, I was just trying to make the same point more simply.
