Croshair..lol

CORSAIR perhaps?

Why not spend a tiny little bit more effort and spell it properly?

corsair the best one around, runs at lower voltage than other brands which means it can be overclocked easier and better factory specs

1.8-1.9v for 800mhz 5-5-5-18 other brands need 2.1-2.2v to achieve this

1.8-1.9v for 800mhz 5-5-5-18 other brands need 2.1-2.2v to achieve this

The JEDEC standard for 800MHz CL5 DDR2 is 1.8V and all RAM rated for this speed or higher should manage it at this voltage otherwise they wouldn’t be compatible with typical systems which don’t allow BIOS adjustment of RAM settings and will run at the SPD settings on booting.
As an example the Elpida RAM in my system has SPD settings of 800MHz (effective) 5-6-6-18 @ 1.8V

Going above 1.8V should only be necessary if you’re running higher clock speeds and/or tighter latencies. Although I had some OCZ 900MHz CL4 that ran at 1,000MHz CL5 at 1.8V with no problems; it wasn’t stable at 900MHz CL4 at that voltage though.

Stunning price! We were talking at work the other day about how it used to be £1 a meg back in the day!! If Vista was around in those days it would have cost over £4000 just for RAM!!!

£1 a meg? You must be a young whipper snapper! It cost me just under £100 to put 4MB in my old 386!

Anyway, this is an excellent deal, sorely tempted.

Wish I hadn't read this thread; I have this memory (2GB) and just ordered another 2GB of that cheap ****** PNY stuff from Play :(

I remember paying £50 or something like that for a 16k ram pack. That's not even enough for a decent icon nowadays. 8-)

Was just about to order this for my laptop, but then noticed the comment in the deal description about 32-bit operating systems not supporting 4GB of memory. Is this true??
#12
Is it correct that it's not advisable to install 4GB of Ram with a 32bit operating system? Didn't know that, just thought the more Ram the better! Would 2GB be better than 3GB in a 32bit environment then, seeing as 3GB wouldn't run in dual channel mode presumably?

It's not a case of inadvisable, a 32bit os just won't be able to use more than about 3.2GB of it due to way addressing works.

Installing 4GB is fine but the most that Widows will be able to use is about 3.5GB; it depends on the peripherals installed.

And then it would wobble and crash your ZX81 anyway :-D I soldered mine on after losing far to many laboriously typed programs...

Sadly not, it was a paupers machine compared to my friends 486DX, especially when the flash git spent about £400 on a 540MB hard drive for it. :-D

Back on topic I have 4GB installed in my laptop running XP, and have suffered no problems apart from not being able to use all of it.

LOL, rampack wobble! that takes me back.

Ahem yes, on topic, I get 3.4gb available in XP and have enabled the 3GB switch that gives some games that request it, more available memory.

You just add /3GB in your boot.ini like so

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /3GB

From Microsoft
"The /3GB switch allocates 3 GB of virtual address space to an application that uses IMAGE_FILE_LARGE_ADDRESS_AWARE in the process header. This switch allows applications to address 1 GB of additional virtual address space above 2 GB.
The virtual address space of processes and applications is still limited to 2 GB, unless the /3GB switch is used in the Boot.ini file."
http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx

Only works in the Pro version of XP, not Home. Maybe someone will find that useful but really just wanted to LOL at the rampack wobble post. :-D

I had a 486 25Mhz Olivetti computer with 4MB Ram and a 70MB HD. Had to delete everything except Windows 3.11 just to install Doom on there, and then needed to use a boot disk just so I could play it!

ahhh, those were the days!

This is desktop RAM and not suitable for a lappy anyway.

Oh really?? I didn't even know you had to get specific types! Good job I didn't get any then. What's the difference between the two? Physical size?

yeah, physical size, laptops use much smaller SO-DIMMS, if not sure just what need, best to use something like crucial's ram checker to see what is needed.

I don't know. I have the very memory advertised, and while it works quite well, it is not amazingly fast. CL5 is about the slowest category you can get - for more performance you can go with CL4, at the same voltage. You only really need over voltage for CL3 at the moment.

And I got my pair for 30 GBP, so this is a good, but not an amazing price.

Instructions for the 16K Rampack included this little gem:
"A little mental arithmetic should show that the computer can theoretically handle up to 960 program lines when fitted with the [16K Rampack] expansion pack. In practice, no program, is likely to need this much (no prizes for trying!)"

when i said "other brands" i didn't mean "all other brands" OCZ and Patriot I know come at 800mhz with 2.1-2.2v going through...that's not good, means they are just 667 overclocked...

Those two companies make mainstream and enthusiast class products and I can guarantee that all their DDR2 800MHz RAM or faster will run at 800MHz CL5 at 1.8/1.9V regardless of whether they are rated for 2.1 or 2.2V.
When you see RAM rated for 2.1/2.2V it means that it’s designed for over-clocking and that it’s safe to run it at those high voltages and it doesn’t void the warranty. At those voltages it will run at 1066MHz CL5 or 900MHz CL4 or something similar. The best RAM chips are chosen for those modules and they use heat-sinks as well to cool them as they need it at the speeds and voltages they are designed for.

RAM that needed 2.2V to run at 800MHz CL5 simply wouldn’t be able to POST in most systems so manufacturers wouldn’t release it. The BIOS when on auto loads the SPD settings directly from the RAM sticks which is usually 800MHz CL5 even for RAM rated at 900MHz CL4. This guarantees that the RAM is compatible with almost every system and don’t forget that the vast majority of systems offer no adjustments for RAM settings and are also usually limited to 1.8/1.9V.

Note: I had some OCZ 900MHz CL 4-4-3-15 RAM that was rated for 2.1V but was happy at 1,000MHz CL 5-5-5-18 at 1.8V.

LOL last year I paid £32 for 2x1Gb of cas4 sticks of this stuff (to go with my 2x512Mb!).

A hot but sickening deal ! :)
