Types of ram

[saftey]

I'm totaly lost about the types of ram i hear about 2100,2600, and 3000 whats the differnce if my friend has a soyo dragon plus with a amd xp 1800 can he mix and match any type ?

 

[minendo]

No you can't mix and match different speeds or sdram/ddr. Check the motherboard specs to see what it supports.

Edit since thread was moved to proper forum.

2100 is DDR. 2700 is overclocked 2100 until later this summer when official PC2700 DDR is released in a standard across the board.

are you saying that crucials PC2700 DDR is just overclocked memory?

 

[notfred]

I have 12 second Honda ram! It's way faster than your crappy DDR ram. I swear I have it, I can prove it, I'll show you pictures!

there is no link to pictures in this post <-- note

 

[NikPreviousAcct]

Yes. I talked to Crucial myself about a month ago. They told me that the only official release of PC2700 DDR has gone out to businesses for testing purposes only. They'll release the official, real thing DDR this summer.

Thanks ffmcobalt so thoose are the only types there is no 3000?as for you notfred you obsessive wierdo why dont you come down to where i live and put your money where your mouth is.

 

[NikPreviousAcct]

As far as I understand it, no DDR PC3000 even exists outside of any sort of prototype lab, if even in there.

so whats the point of places like Mushkin and Memman selling PC2700 and PC3000, and if its just the same chips overclocked, then why does it cost so much more? And places like Newegg that have Samsung PC2700 with statements like "not overclocked, true PC2700 chips"

And why are they calling it PC2100, 2400, etc... why dont they call it frickin PC266, PC300, PC333, PC366...etc... I mean, who really thinks that they are getting 2100mhz ram.... PR SUCKS?

ok im done

What about Rambus's PC600, PC700, PC800, and PC1066?

They hire some PhD in CS and EE double major to hand-pick the ram and try overclocking to some levels. You've to pay so much more for hand-pick, you should know labor cost for everything - car service, onsite computer service, whatever is extremely expensive in the US. Worth or not, you decide.

And places like Newegg that have Samsung PC2700 with statements like "not overclocked, true PC2700 chips"

That's real PC2700, no need to hand-pick and try overclocking, so about the same price as regular PC2100.

 

[LordAccord]

well, hey, theres an explanation for everything.... eh?

I do wonder though.... why wouldnt you be able to put a PC2700 stick in with a PC2100 stick? Its just going to run at whatever bus speed you desire, as long as its good ram shouldnt it work together at a speed that the lowest stick can handle.... I have had a stick of PC133, 100, and 66 all in the same system at the same time, all running at 66.... Does that principle not apply anymore or something?

I ask, I was planning on buying 2700-3200 for my next upgrade in a system that will likely only run the ram at 266....theres no good reason why that wont work.

Nobody said that. Good memory modules have good SPD, motherboard's BIOS will know what speed and timing to run at when you put in 2 or 3 different speed memory modules.

Repeat, buy good memory modules with good SPD only.
I've a Mushkin basic pc133 module with unknown chips, its SPD is full of error, stay away from Mushkin. It sucks.

err maybe because u bought BASIC. lol thats like VALUE RAM..

Mushkin sells good memory. They basically use Samsung or micron memory on there own PCB. There customer support is great. I have some of there PC 3000 stuff and it rocks.

if u buy mushkin dont buy BASIC. that stuff is juts memory they get from unkown place. they dont make the PCB or nothin.

 

[xynder]

Samsung pc2700 is "True," and not overclocked 2100.

I knew I was right, I just like to hear other people say it

memory speed is backward compatible like hd interface speed.
you can mix, either run at the lowest speed (set to auto spd, assume each module has proper spd) or overclocking at the highest speed (disable auto spd, set your own speed and timing).

He means you can't put in one 2700 and one 2100 and expect to run at 2700.

I don't see how you interpreted his post that way, but most people read a sentence and take it to mean exactly what it says...

I have the SOYO Dragon Plus as well. I am running one gig of Mushkin DDR2400- (2) 512 chips. I was told by a reliable source that the SOYO Dragon Plus, though offered as a board that can handle 333Mhz RAM, does not actually attain that bus speed between RAM and CPU. So, I concluded that it was pointless to buy the 2700 and opted for the 2400. I have had no problems, and I have all my friends slobber all over the bitchen looking Silver RAM moduals with the heat sinks. They are also pushing me to get more, and run everything from my RAM and not the hard drives, but thats another story...

later docgonzo

The concept of different ram speeds is similar to the concepts of processor speeds. Essentially "faster" ram only means that the process has been refined enough (or modules have gotten good enough with low enough latency) to allow for higher clockrates and data throughput from the ram. So a "new" ram is released. Normally a new "speed" of ram would mean that the manufacturing process was somehow improved over the previous one. For instance "PC100" SDRAM was normally made with 8-10 ns modules while "PC133" was normally made with 5-7 ns modules. This isn't a neccessary thing as 8 ns ram that could make it to 133MHz with the same cas and ras delay would perform and, in every other way be just like 7 ns ram at the same clockrate. So really the difference between "overclocked" and "true" is normally neglegible.
As for the "PC2700" ram, Crucial apparantly have been able to produce ram that is made on the same process as "PC2100" and in fact was originally meant to be "PC2100" but have been able to make 166MHz DDR. There's no need to not release these yields at higher clockrates for a higher price simply because of some connotation of "it's not true PC2700". In every way and form it is PC2700, it's running at 166MHz DDR with cas 2 (in most cases) latency.
People who hear the word "overclocked" and think it's somehow less effective than "true" are fooling themselves. You don't see anyone claiming the GF3 Ti500 is merely an "overclocked" Ti200 now do you?

It's not a PR rating of sorts. It's the amount of bandwidth. 2100 = 2.1GB/sec, 2700 = 2.7GB/sec, etc. Unless you mean it's a PR thing because it uses a bigger number, but then so is PC266/300 etc (because it's not really 300MHz, it's 150MHz double data rate). If it was purely a non-PR rating system, it'd just use nanosecond rating.

There might be a difference in something like Corsair's XMS3200 and true PC3200. There was a debate about the standards of higher clocked DDR over which packaging they would use. I'm not sure which one was eventually chosen and which one all the manufacturers are using in the overclocked models (one camp wanted to stay with the regular packaging because it's cheaper, the other wanted to move to another to prepare for DDR-II, if I remember correctly).

It's much like how the Ti4200 uses TSOP DDR SDRAM and the Ti4400 and Ti4600 uses BGA DDR SDRAM. Sure you could overclock the Ti4200 to Ti4400 speeds, but the RAM is still technically different.

Thanks for the insight, I didnt know that was the bandwith rating on the RAM.... but I still think that 266/300/333 rating would make more sense.....
