Looking for specific RAM

[Gibbo]

Any ideas where I can get some Samsung PC4300 RAM 2 x 512Mb 533MHz - yes PC4300 (not PC4200) to match my current RAM?

Google has not been my friend.

This guy does 1GB sticks and he is reliable. You could ask him if you have the part number. I have used him several times before.

I need someone in UK

Whats the difference ram is ram. It takes a few days longer thats all.

in case it's u/s and i need to return it

[redlight]

Of course but I think returns go to Birmingham. Not a 100% sure though.

Eh?

They're exactly the same thing.

I thought they had differing CAS latencies?

[kalniel]

Nope. The PC rating only varies with speed, not latency. It's the real speed x16,

so 266mhz ram (what core 2/AM2 uses) is 266x16 = PC4256

Obviously that's not a nice round number so they round it to either PC4200 or PC4300.

TA - Can't find Samsung in the UK anymore anyway.

I can only find single 512mb sticks suppose you could risk it and buy 2 and hope they match

£27 a stick

Why do they need to match?
Please dont say "Dual DDR" or anything along those lines or im going to go nuclear....

Go on then do your worst!! Put on a good show!

Explain to me that it doesn't matter if they don't match as they will all follow the lowest common denominator.

I have tried mismatched memory in the past with poor results insofar as I have had boot problems and memory errors. I swore many moons ago that I would never put mismatched on the same mobo ever again. It was more trouble than it was worth last time!!

Of course you could always try to get me to see the error of my ways and revert to what I now see as a risky stategy.

LOL Fight on!!!!

There is little gain in the "real world" maybe 5% which probably translates to 1fps when using dual channel. Thats Custom PC's findings.
However if you have had memory issues with mismatched memory then its probably th elast thing you want to try again.

Ive done endless posts on this, have a search (im going out in a matter of min's otherwise id go into it more)
But simply, its not the RAM at fault if it wont work in Dual DDR mode, its the motherboard BIOS not addressing them correctly.
If you *ever* get memory issues when running RAM in D-DDR mode, but they work fine seperatly, its a motherboard issue. Period. Moan at the mobo makers for being lazy
Then you have to remember that a LOT of RAM is the SAME, just with a different SPD table, depending on what its sold at.

If you want to stick on the safe side, buy RAM that uses the same chips as your existing one. All the big companys do is take these, wack them on a PCB, set the SPD table to what they want to sell it at and sell 'em.
Heck, these chips change over time anyway. You could buy RAM from the maker and at the same rated speed with different chips, and get the same issues when you try to run them in D-DDR mode.

But generaly speaking, even with mixed RAM, problems dont very often happen (im not saying they dont!)

And lets just keep in mind that D-DDR is the biggest con ever. The difference is so small its almost useless.
Compared to the price it costs for 'matched' pairs and problems which can happen, I just dont get why people even bother with it.

I can certainly back this statement up with RAM of the same speed but different manufacturer.

I was running 2.5gb with 2x1gb stick of different manufacturers and it ran in D-DDR mode, and i had another stick of random RAM at 512mb.
