Nope it will see roughly 3.5gb as this is a limitation of vista 32bit. If you want it to see all 4gb you need to go for a 64bit OS

Yup that is correct. Its also worth noting that even with Vista 64bit you may still not see the full 4 gig due to resources reserved for the motherboard.

Hot! Ordered a set just now - I ordered these exact same ones from ebuyer last year at £99.99 + VAT!!! (which ebuyer is currently £34.99 - http://www.ebuyer.com/product/116755)

The amount you can use will be less than 4GB as some of the address are used by the system and video card memory. Vista may show 4gb installed with SP1 but it not all being used in 32 bit, 64 bit can use 4gb and a bit more.

good stuff - hot !

32-bit has a limitation of 3.5gb, the other 0.5gb is shared between the GPU. Changing to 64-bit Vista can recognise upto 8GB. But having 4GB RAM powering a 64-bit isn't all happy happy! As 64-bit has a large memory map. Either ways your still going to be experiencing the same thing. But, having 6GB or 8GB on 64-bit is brilliant, you can really feel the speed changes. As more RAM allows the CPU to not have to access HDD all-the-time, which increases speed & performance. If you do want to change to 64-bit consider buying a Intel Core 2 Quad, a very good processor with the right stable OverClock you can be doing all-sorts of things. Stock = 2.4Ghz, OC'd with good cooling can go up near 4Ghz, which is more than enough.

Sorry, i get very technical sometimes :p

CL 4-4-4-15 timing = not amazing. If this wasn't 800 FSB it wouldn't be good. You could probably get faster and cheaper 633Mhz FSB if you looked about on the Internet a bit more. Some of Kingston's ValueRam is prob on a par with this. Although you could overclock this if you know what you are doing and that would make it more worthwhile, overclock it too much and it will crash your system and void the lifetime warranty so be careful.
#16
With a 64bit Os the smalest read is 64bit word even if its only using 8bits for a character say, so 64 bits can be wastefull. 32bit has only 32bit address space so if your graphic memory is 640 MB that is then gone plus ROM and IO address will leave less than 3.5 GB free.
#17
4-4-4-12 timings arent amazing? I only know of ONE DDR800 stick thats lower (a Mushkin one) of CAS3 that costs the EARTH. My Ballistix run at 4-4-4-12 and they are premium grade overclocking sticks.You can get faster 633 MHz sticks, but they will never have the raw bandwidth DDR800 has, and so on an Intel platform will never be as fast. To compare these to Corsair ValueRAM is a little unfair as these are of a higher grade (these are actually good for up to about 950 MHz) - although these are no Micron D9 chips.

Im running on these right now - paid £35 + P&P from eBuyer, though.

As far as i know OCZ/corsair/g.skill and geil support overclocking as long as you dont go over the rated voltage. The speed of 800mhz would easily allow you to have an fsb of 400([email protected]) so with a 9x multiplyer(most c2d use 9 now) thats 3.2ghz and thats pretty good.

My corsair 2x1gb dual channel pc6400 cas 4(4-4-4-12) are overclocked to 950mhz and stable, wanted to keep the nice 1:1 ratio with fsb and ram speed so its @ 820mhz now, the timings are amazing for me, i have them @ 4-3-3-4 which i think its really good, will push it quicker tomorrow.

Voted hot as i bought my corsair for £35, and this isnt from overclockersuk, perfect shop now :)

Nice price. Was £70 a year ago!

DDR2 is falling rapidly in price due to the emergence of DDR3, so it's a great way to beef up your system.

You can get 8GB DDR2 for just over £100 now, madness.

Good deal though, thanks. :thumbsup:

Hi, I was thinking of getting one of those DELL inspiron quad core systems.

http://configure.euro.dell.com/dellstore/config.aspx?c=uk&fb=1&l=en&oc=D025012&s=dhs

This comes with 2gb DDR2 667 ram. Can I get a pair of these and would they work together to make 4gb?

Many thanks

#27
This is very good memory BUT to work well at the higher speeds you need 2.1v - this is higher than standard. 2.1v is not available with all motherboards & you might have a problem if adding it to memory that you already have that is less than 2.1v

Any chance you know your motherboard model? if so, post here or google it :).

the thing with ram is that they should work together, if you purchase this ram it will follow with the lowest speed ram so that instead of running @ 800mhz they will be declocked to 667, not a problem as you can simply overclock the set up to 800mhz. If you have 32bit Operating system then i wouldnt recommend buying as too use the full 4gb you need 64bit(xp or vista) as 32bit can only use/see 3gb and the rest is given to other things, e.g. you have a 512mb card(8800 or what ever) then you will see 3.5gb and it wouldnt give you a performance increase.
Also note that too use 4x1gb of ram stick(well 4x any sticks) you will normally be required to up the voltage of the ram as it requires more power, simply set them up to 2.1v if it doesnt work or too what ever the max rated voltage is(too keep warranty). Any other questions?
Also make sure your motherboard can support 4gb, i am 99% sure it will as any motherboard with 4 slots will work upto 4gb +(aslong as they are newish, few years xD). Do you know how to run them in dual channel? make sure the pair are in different channels, if there is 4 bays then they should be named(in manual) similar to this: a1 B1 A2 B2, so first stick in a1 then the pair to that should go to a2 etc, make sure the lowest clocked ram is in the first channel(the 667mhz).

2.1V is standard, some are 2.5V which is more then standard. i know corsair give you a ~5% difference in voltage as the motherboard sometimes goes past 2.1v increments, this should be the same. 2.1v should be a maximum and having 4x1gb @2.1v should most certainly work :).

Sorry, i get very technical sometimes :p

its a pitty you didnt know what you were talking about 64bit O/S'S can address way more than 8gig of memory what do you think they use in servers? ill tell you 64bit they can also use multiple cpu's heres a chart before spouting technical facts make sure you know what your talking about


Windows Vista Ultimate 128 GB
Windows Vista Enterprise 128 GB
Windows Vista Business 128 GB
Windows Vista Home Premium 16 GB
Windows Vista Home Basic 8 GB

Most 64-bit consumer PCs on the market today have an artificial limit on the amount of memory they can recognize, because physical constraints make it highly unlikely that one will need support for the full 16.8 million terabyte capacity. Apple's Mac Pro, for example, can be physically configured with up to 32 gigabytes of memory, and as such there is no need for support beyond that amount

Sorry, i get very pissed off when people say things they clearly know nothing about

Seems to be a winner. Amazon.co.uk is a listed site that they will beat by 10% (excepting televisions).

Go man go!
#32
thanks everyone for the technical advice...

i'll probably get one of those DELL quadcores in the next few days and top up the 2gb with this 2gb. I guess it's only going to run at the slower speed but still that's pretty good value and maybe i'll sell the 2gb that comes with the DELL and get another two of these!

:)

Cheers everyone

My current RAM (Kingston ValueRAM) runs at 5-5-5-15 timings. What sort of performance gain would I get if I use these OCZ modules at 4-4-4-15 ? It would cost me about £10 to upgrade 2GB (after selling my existing RAM).

No 1.8v is standard. Not all motherboards will give 2.1v & this can be a particular problem if you are adding memory to some already in the machine. I suspect that Dell for example - & specifically mentioned here - run their memory at 1.8v.

Nice copy and paste from here: http://en.wikipedia.org/wiki/64-bit#Memory_limitations

:oops::oops::oops::oops:

This is definately decent RAM for the price, follow some overclocking guides and you will see a nice increase in performance :)

If you are unable to upgrade or add memory to Vista then use a memory stick for ReadyBoost which is half way compromise between memory and disk for performance for the Vista paging file. 4 GB stick is about £12 at the moment.
#37
OK,complete novice here.

Is CL 4-4-4-15 Memory better or worse than CL 4-4-4-12 Memory?

If my PC takes CL 5 Unbuffered Non-ECC DDR2 Memory.....will I be able to use this OCZ stuff :?:

ReadyBoost is **** - it will provide no noticable improvement if you have more than 1 GB of RAM.

Nothing is a substitute for more RAM.

At the above poster - lower timings are better (the first number - the CAS# Latency, aka CL is the most important) - so 4-4-4-12 is better than 4-4-4-15. On an Intel system timings don't make that much difference, though.
#39
For "DerryBhoy".

Theoretically it should work but it depends what voltage your motherboard can supply, and what speed it is. Do you know what your motherboard is?

DDR2 standard voltage spec is 1.8v - these run at 2.1v. As such mobo's like the P5K are hit and miss as they will supply 1.8v unless you go in the BIOS and change it, and if the memory won't run at 1.8v (these wont) then it wont boot up at all - as such you'll need to set the voltage to 2.1 in advance.
#40
Does anyone know if this will work with my Dell Inspiron 530?

Got 2 gig just now, but no idea of the timings or voltage etc.. I've never upgraded memory before, but am keen to do so.
