Is there compatible ram for 533

I have just purchased an Intel Celeron D 2.8gh 533mhz with 512MB ram I want to up grade this so I have either 1x 2GB or 2x 1GB sticks. Apparently 533mhz sticks are rare to get and I was wondering is there anything compatible?

More about : compatible ram 533

April 14, 2011 7:08:02 AM

if i recall without looking up exact specs
I believe that it uses PC2100 DDR 266mhz,PC2700 333mhz DDR or possilbly PC3200 DDR
double check crucial memory website (google)
I like their memory finder
usually all three would be compatible with each other
would want to run in matching pairs if possible (2 x 1gb)

One issue is that older ram is WAY overpriced
If ebay is available then probably best choice
or craigslist which would be cheapest but with no return policy obviously

I just bought ram off of craigslist
seller nice enough to let me bring my tower and set up and test

the way you listed specs makes me believe that the Celly D is 533mhz Front Side Bus
which the fsb would not be speed of ram
usually speed of ram is approx half of fsb as general rule

if you are referring to 533mhz ram that would be pc4200 ddr2-533
usually compatible on most motherboards with DDR2 667 and DDR2 800
with DDR2800 being best choice

If you pull memory stick currently in tower they almost always are labled

if it is a OEM factory tower then you can check crucial or oem website for specs

newer ram like DDR2-800 will be cheaper than older and better performance wise

DDR2 and DDR are not interchangeable

sorry if this post is rambling

Hi king smp, i just bought this computer from a government auction the only details i can give you at the moment are;
Intel Celeron D Processor 335J (256K Cache, 2.80 GHz, 533 MHz FSB)

I'm wanting to turn it into a media centre

okay going by those stats
it is ddr and pc2100 266 or pc2700 333 or pc3200
really pc3200 would be fine in this situation
though i would have to research before recommend buying it

more than likely need unbuffered non ecc ram standard ram
it is 184pin
shame of it is I have many sticks laying around ( i refurb older towers for cheap
browser/email/beginners computers)

i would avoid spending more than $30 USD for pair of 1gbs
buying used where you can test first and get real cheap is best bet
check your local computer repair shops (not stores) and those guys
will almost give them away

when you get tower open up and look at sticks
almost always labeled
stick to same CL number (usually 2.5 or 3 with this speed)
try to stick to same timings
search wikipedia for "timings" for explanation

apparently i can upgrade the processor to a P4 3.4ghz. Ive had a local store check this out and they have said that i can put a p4 775 3.4ghz with 2gb.

does this sound right to you?
April 14, 2011 12:27:40 PM


intel specs

socket 478 NOT LGA775

there is a P4 3.4 socket 478
I wouldnt use it
rather have P4 3.2 Extreme Edition 3.2 S478
because much more common and cheaper
no performance difference

Need to know mobo model number and chipset to
verify compatiblity

avoid that computer shop like the plague
if they are giving you that advice
30 seconds on Google I knew that was wrong
April 14, 2011 12:29:06 PM

especially need to know if motherboard supports
800mhz FSB
crucial to using better CPU

hi king. thanks for the help. i really appreciate it.

Ive pulled the ram out and this is what is on it;
512MB UNB PC2-4300 CL4

Does this help with my earlier question?

Or do you still need more info?

Hey Looksd like you have 336, not 335
Then you was given the right advise the first time. You probably can put p4 775 3.4ghz with 2gb.
April 15, 2011 7:05:08 AM

I was completely WRONG
disregard my info

this is spec sheet from intel for cpu

this is spec sheet from intel for supported cpus

that shop was right it can support highend Pentium 4 EE and also Pentium D 8xx and 9xx processors

that shop was right
I apologize for wrong info

here is link to stores selling ram
you are exactly right it is hard to find

DDR2-667 PC2-5300 would be compatible
and much easier to find and also a little faster

here is link to 945gtp specs

here is link to Intel support page for board

the specs sheet says it will handle

you could put a Pentium D 9xx series dual core in there
but they are generally overpriced and run hot so
if you can find a really cheap deal and your cooling is good enough
for the Pentium D that would be fastet

if you have a cheap deal through that shop for the Pentium 4 3.4
then that would be fine as a basic HTPC rig

Sorry again

I didn't realize there were any S478 Celeron Ds. He also said it used 533MHz ram, which is DDR2, not DDR1 like S478 used. Finally, his last post says 945 chipset, which is a DDR2 and not DDR1. The OP should be able to buy any DDR2-533, 667, or 800 MHz ram and it should work. Not 100% guarantee, so make sure you know the stores return policy.
April 15, 2011 7:13:07 AM

don't apologise mate. its my fault for not having all the details in the first place.

thanks heaps for the help guys. :)

Yea I realized that and corrected my info

I was wrong

the intel specs for mobo posted in my other post
list DDr2-667 as fastest supported in that Intel board

I am up on this computer until 5 or 6 am (insomniac)
and at about 5 am I should stop giving advice :) 
April 15, 2011 7:28:06 AM

LOL. I'm on this until about 8am, but I work nights...

I work from home and make my schedule

one thing is the wife,kid and dog are sleeping
so alot less distractions

My celeron d 3.06Mhz handles Xp media center ok with only 1Gb of ram. It can get bogged down thou. This is running a std def tv. I'm not sure how well it would work with BluRay.
April 16, 2011 9:31:45 PM

Hi guys. got another question for. I've found this Intel Pentium D 945 3.4GHz 800MHz 2x2MB Socket 775 Dual core and I know by looking at the mother board specs that it can handle it. Is this excessive for a media centre?
April 16, 2011 9:58:31 PM

no not at all
I had that same exact CPU
It is decent enough
it was just a little less powerul than my C2D E4300 1.8
I would just worry about heat
The pentium Ds ran hot
as long as you have a good HSF cooling setup then
you would be fine
April 16, 2011 10:59:10 PM

any good suggestions for fans?
April 16, 2011 11:19:05 PM

I think this is good
it is a zalman that fits 775/1155/1156 so it could be used for newer builds later
also is on the quieter side
it is normally 54.99
but 32.99 after MIR

there are plenty of other options
I would try to get one that is designed for more than the LGA775 socket
so it could be reused down the road
