What,s the difference between DDR Ram v SDRAM?

 

[Mr.Scott]

Difference between DDR and SDRAM:

SDRAM is waiting wait for the completion of the previous command to be able to do another read/write operation.	DDR is not waiting wait for the completion of the previous command to be able to do another read/write operation.
SDRAM prefetch timing is 1ns	DDR prefetch timing is 2ns
Data rate of SDRAM is (0.8-1.3) GB/s	Data rate of DDR is (2.1-3.2)
SDRAM’s Internal rate range is (100 Mhz-166 Mhz)	DDR’s Internal rate range is(133 Mhz – 200 Mhz)
SDRAM speed is considered as 66 MHz, 100 MHz, 133 MHz	DDR working on speed as 200 MHz, 266 MHz, 333 MHz, 400 MHz
it’s working on 3.3 volts	it’s working on 2.5 Volts (standard); 1.8 V (low voltage)
SDRAM has less speed in comparison DDR	DDR can transfer data at roughly twice the speed of SDRAM.
SDRAM was released in 1997	DDR RAM was released in 2000
SDRAM has 168 pins and two notches at the connector	DDR has 184 pins and a single notch at the connector.
It refers as synchronous dynamic random access memory	It refers as Double data rate SDRAM
SDRAM	DDR

Thanks for explaining all that to me, very informative Scotty

To make things more confusing, full name for DDR memory is this :
Double Data Rate Synchronous Dynamic Random Access Memory.

After DDR was introduced, earlier SDRAM standard is often refered to as SDR SDRAM :
Single Data Rate Synchronous Dynamic Random Access Memory
(And some say GPUs have long model names)

Table compares SDR vs. DDR, and not SDRAM as a whole to DDR memory.

Isn't DDR just a further development of SDR SDRAM?

Use brand name CF cards only. Lexar, Sandisk, Kingston and such.. Avoid no name brands..

There is too much dubious - or outright fake capacity - flash memory out there to trust any no-name brand, at least from some random online source. Cheap, off-brand stuff can be acceptable if it's from a trustworthy source (store brands from major retailers etc.) but the general rule is always to go for something trustworthy. Searching for that title you posted above only linked me to really dubious sources that I would never trust to sell a decent product like this. Sandisk, Transcend, Lexar, and Silicon Power are current good quality SD card manufacturers. Oh, and for the record, Amazon is not a trustworthy source for these types of products, as their supply chain is a complete mess.

I get that paying $8 sounds a lot better than $45, but when that $8 gets you a piece of garbage that either never works or fails rapidly, that's just $8 in the trash. It's not worth it.

Exactly! When it comes to storage for retro systems, buy quality! Windows 95/98/ME will run perfectly on 16GB of storage. 32GB would be better, but 16GB is very doable. 16GB doesn't sound like a lot these days but remember, back then 16GB was a lot and 32GB was HUGE!

EDIT;
On Amazon UK I found the following:
8GB from Transcend for 18GBP;

https://www.amazon.co.uk/Transcend-Compact-Flash-133x-Memory/dp/B000W05O5O

The 16GB model is a better value at 24GBP;

https://www.amazon.co.uk/Transcend-Compact-Flash-1000x-Memory/dp/B009S61AC4

However the 32GB Sandisk model is the best value at 33GBP;

I get your point there like you say you can get fake cards on Amazon that look like the real thing but are not.And with Ali Express and eBay.I never used to check them tell recently i am talking about SD cards with the free app you can see if they are fake or not. I have never bought any CF Cards before.I will just go for the name brands. There seems to be a lot more Sandisk cards about then the other makes Lex mentions on the UK anyway.You get what you pay for as the saying goes.

Thanks for that Lex I see that is

Transcend 32GB CompactFlash 133 Memory Card (CF Card) Up to 50/20 MB/s, Supports Ultra DMA transfer mode 4 with MLC NAND Flash ideal for entry-level DSLRs TS32GCF133​

Just for 8gb you are paying 17.90 and yet 16gb is 28.95with the 32gb you are only paying 2.80 more for a card for an extra 24gb . Why would any one go for the 8gb
one when you can get an extra 24gb for just 2.80?And it has DMA which Phil is all ways talking about.Does anyone know where i can get a CD SPD IF Cable from a Audigy sound blaster sb0090. to a dvd drive?

 

[Greenslade]

Can someone give me a link for a
*CD SPD IF Cable from an Audigy sound blaster sb0090. to an ide DVD drive?
Here's a very old PC

does anyone go that far back to have owned one of them? It must have been a hell of a job to do anything on one of them.

 

[68Olds]

Is this the 2 pin to 2 pin cable you are asking about?
Amazon.com: SPDIF Cable 2 Pin (Sound Card to DVD) : Everything Else

Another option is this cable that goes from the CD/DVD drive to the SB CD IN. I don't know if they have different purposes.
Amazon.com: Kentek 18 Inch 18" PC Computer Internal 3/4 Pin Sound Blaster to MPC-4 CD-ROM DVD-ROM Audio Cable CBL : Electronics

I can't find a SPDIF Cable on Amazon UK.

Thanks once again for your help. But it needs the 2 pin for the soundblaster as in the amazon one, but from the ide dvd drive below it needs a biger one there.I don,t know what the 2 pin one is for next to the bigger 3 pin one.
And why don,t they say. there is a cable on the HP Compacq
from the DVD Drive to the motherboard that has the biger conecter that should go to the DVD Drive according to the dvd drive pictured.
Does anyone know what the 2 pin one at he end is for ?another analog Audeo ?

 

[stinger608]

You really shouldn't need that little 2 pin audio cable @Greenslade

Usually the IDE disk drives will play audio without that being attached.

But I want to use the Soundblaster as sound.

 

[GreiverBlade]

But I want to use the Soundblaster as sound.

the sound will come from the SB card no worries ... my Duron/Athlon XP build back in the early 2000s never had the cable from the drive to the card, which were a Guillemot Hercule Gamesurround Fortissimo 2 and a SB Audigy 2 (or mobo ... good ol' VIA8237 AC '97 audio ) and i played CD audio without any issues.

I see from this video that the 2 connections are for digital

So if I get that cable 68ILDS gave me a link that would be the right one to get as the Soundblaster has a 2-pin Digital as the guy says in the video. 7.20. in to the video,

 

[GreiverBlade]

I see from this video that the 2 connections are for digital

ahah i used that trick (using a PSU and a standalone CD drive that had a volume dial and a 3.5mm jack) during my army time to improvise a sound system in the bunker we were stationed, during my time serving as an embassy guard, i had a boomy 2.1 speaker setup i can't remember the brand or the model but it had a barrel shaped sub (more bullet technically, woofer on one end and air hole on the other )

although this is wrong ... digital should also be carried by the IDE cable oh wait the 2pin yeah, it's digital, the 4pin was Analog, this is overly weird tho why need a 2pin digital when the IDE interface works just as it is, for the 4 pin analog i can understand.

The Analog one on the PC I found was a DVD drive to the motherboard. 4 pin.
The guy in the video said the 2-pin connection on the DVD Drive was digital and thought
it would be using the digital sound on the Soundcard. CD SPD IF as opposed to using the onboard sound.

mmhh i think it will be fine ... the only Pc using the analog or the digital cable from CD to mobo/soundcard i had was older than a Athlon XP (iirc even the K6-II which was my first self assembled build i did ) never used it, and the digital signal, in my understanding, went from CD to mobo via IDE and then to soundcard via PCI ... and i remember the tech at the PC shop telling me that theses cable (2 or 4 pin ) were not really useful, which at the time i found strange since all mobo/soundcard/CD-DVD drives, had a 4pin on them (2 pin less often seen) thus later i simply used one for Analog testing, but never for Digital.

on my MSI KT6V 400 i just disabled the VIA AC '97 Audio and cable or not : the soundcard was the output

btw ... @stinger608 also confirmed IDE did carry the signal ... and i confirmed the soundcard will work just fine as it is (unless you have a very specific setup that needs it, tho i highly doubt it )

So the sound will come from the Soundblaster, not the onboard sound?Without the cable not connected? .There are two cables on the second and and third the cables are stuck in there i don,t see much point in them.Why do they put conections
on there if they are not needed?

oh, i suppose, if it was working for me ...

B.T.W. the card i used in all my Socket A builds...

Spoiler: also if my confirmation was not enough

S/PDIF is digital and is doing thru the S/PDIF (Sony/Philips Digital audio Interface) connector, either a 3.5 jack or a RCA

(warning : joke) now with all your reply and questions, i am not sure anymore... am i lying, was all my tech life since 1985 a lie? (end of joke )
no worries i do not mind repeating myself, confirming and reconfirming while adding other things that remind me that i still have the stuff i talk about around my Livingroom hehehe

as for why the extra cable, i think it's probably if using a drive only for audio and not connected via IDE ...
extra options are always welcome even if not needed.
same question apply to PCI connector on modern mobo, not majorly used, but some might need them.

and AGAIN the soundcard get the data it need to output as sound VIA PCI on the the motherboard ... thus if the onboard is inactive (via BIOS, AC '97 in the case of old board) why would the sound come thru the onboard.
