Help me chose some ram.....

[Guru]

1) 2GB (2x1GB) Corsair TwinX XMS2, DDR2 PC2-6400 (800), 240 Pins, Non-ECC Unbuffered, CAS 5-5-5-18 £18.99 £21.84

2) 4GB Corsair (2x2GB) TwinX XMS2, DDR2 PC2-6400 (800), 240 Pins, Non-ECC Unbuffered, CAS 5-5-5-18 £30.99 £35.64


3) 4GB (2x2GB) Corsair TwinX XMS2, DDR2 PC2-6400 (800), 240 Pins, Non-ECC Unbuffered, CAS 5-5-5-18, DHX £43.50 £50.03


4) 4GB (2x2GB) Corsair TwinX XMS2, DDR2 PC2-6400 (800), 240 Pins, Non-ECC Unbuffered, CAS 4-4-4-12, DHX £39.95 £45.94

I don't get why 4 is cheaper than 3? as I thought lower numbers were better?

I currently have this ram:

Corsair 2GB DDR2 XMS2 DHX PC2-6400C4DHX TwinX (2x1GB) @ 4-4-4-12

Would I be better to go for number 2 and have 4x1gb or sell my ram and go for number 4? or go for 4 AND keep my ram aswell?

Or even go for this:

5) 4GB (2x2GB) Corsair TwinX DDR2 XMS2, PC2-8500 (1066), 240Pin, Non-ECC Unbuffered, CAS 5-5-5-15, EPP £53.99 £62.09

It's all a bit confusing but I have till 12pm if I want them at these prices

For info my mobo is a standard Asus P5K (one with super memspeed technology) and I will be using a q6600.

Thanks,

G

/edit forgot to mention I'm currently on XP pro but intend to move to Vista soon enough.

Some guff about my mobo.....

Intel® P35 Chipset
The Intel® P35 Express Chipset is the latest chipset designed to support the next generation 45nm CPU; and up to 8GB of dual-channel DDR2 800/667 MHz memory architecture. It also supports 1600/1333/1066/800 FSB (Front Side Bus), PCI Express x16 graphics and multi-core CPUs.

*ASUS unleashes the chipset capabilities to fully support FSB1600.

Native DDR2 1066 Support
To attain top performance, ASUS engineers have successfully unleashed the true potential of DDR2 memory. While in DDR2 1066 mode, ASUS´s exclusive technology offers a choice of FSB 1333 - providing great performance for 3D graphics and other memory demanding applications.

ASUS Super Memspeed Technology
Surpass the Limit with Easy Overclocking Automatically
To attain top performance, ASUS has managed to break through current FSB and DRAM ratio proportions by utilizing Super Memspeed Technology - the latest technology that provides even more precise overclocking options to unleash the true potential of DDR2 memory. Native DDR2 1066 maximizes system performance by eliminating the bottleneck when overclocking both the CPU and memory - providing great performance for 3D graphics and other memory demanding applications.

No-one replied and I have to go out now so I bought no.4.

Was this a good idea or not?

Can always change my mind if not

Hi Guru, which CPU do you currently have and are you looking to overclock? Which will really determine if you made the right choice.

This Quad I've currently got an e2160, but I'll put that on the MM and use a Q6600 instead, I would also very much like to overclock it to the best of it's ability

Thanks,

Hi Guru, first of all let me apologise, I'm not quite sure how I missed you mentioning which CPU you have.

The memory that you are looking at buying (Option 4) will be absolutely fine. If you are looking at overclocking, then you will be able to overclock your Intel Core 2 Quad Q6600 all the way up to 3.6GHz without even having to worry about weather or not your memory will hold you back. This is providing that you have a chip that will be able to reach that kind of speed before temperatures come into play.

If you are looking at overclocking beyond 3.6GHz then I'm sure the Corsair memory has a bit of room to run at a faster speed itself. However, this isn't guaranteed. You also have to take into account that there are other factors that come into play when you reach around the 3.6GHz mark such as weather the motherboard you have will be able to reach a high enough FSB (Front Side Bus) and one of the most limiting factors especially if you are on air cooling, will be the temperatures.

I don't get why 4 is cheaper than 3? as I thought lower numbers were better?

I'm honestly not quite sure while option 4 is cheaper than option 3 since it is actually better memory due to the lower CAS latency timings. Though, sometimes you do get the odd pricing mistake.

sounds like I made the right choice then got 6gb of that stuff now lol 3.6 here I come (hopefully)
