Hey guys,

So i've finally got a final spec sorted out....just need a bit of advice on ram.
I will be overclocking, and looking at spending about £1000.

The rest of my spec is as follows:-

CPU = Intel Core i7 920 2.66GHz Socket 1366 8MB Cache OEM (£241.49)
CPU Cooler = Xigmatek Dark Knight-S1283V 3 Heat Pipe Cooler with 120mm PWM Fan (£34.49 + p&p)
MOBO = Gigabyte GA-EX58-UD4P Intel X58 Socket 1366 DDR3 Motherboard (193.19 + p&p)
GPU = Sapphire ATI Radeon HD 4870 1024MB GDDR5 TV-Out/Dual DVI/HDMI (PCI-Express) - Retail (£164.99) - PURCHASED
HDD = Western Digital Caviar Black 640GB SATA-II 32MB Cache - OEM (£63.24)
PSU = 750W SilverStone SST-ST75ZF Black SLi/Xfire Quiet Quad 12v Rail ATX12v 2.2 EPS12v 86% Eff' (£80.32)
OS = Microsoft Windows Vista 64-bit Home Premium OEM (£88.51)
Case = Antec 300 (£44.99)
Thermal Compound = OCZ Freeze (£3.44)

Which comes to £914.66....so when i add my ram, the total should come to just over my £1000 budget.

Right...now here's where I need the help with ram...
These are the three i've picked out:-
OCZ 6GB DDR3 PC3-10666C7 1333MHz Platinum (3x2GB) Triple Channel DDR3 (114.99)
OCZ 6GB DDR3 PC3-12800C8 1600MHz Gold (3x2GB) Triple Channel DDR3 (£114.99)
OCZ 6GB 1800MHz DDR3 PC3-14400 (3 X 2GB) Reaper Low Voltage Tri-Channel Kit (£113.99)

Now there is a slight problem with the Platinum one...the title and description are that of a 1333mhz version....but I had a look at the model number, and it's that of the 1600mhz version!!! So i've sent a message to the website asking what the product actually is (i'll post the answer here when I find out).
For now, we'll assume it's the 1600mhz version.

If you could tell me which one is the better buy, and why (so i can learn for next time) I'd be very greatful.
If you choose the Platinum's...could you also pick a second best, in case they do run at 1333mhz.

Once the ram's sorted out...I'll start buying everything in :)

Thanks in advance!

IMO get the platinum 1600. If you plan on overclocking you're going to want a RAM that has enough headroom. For example, if you're looking to push 4.0 ghz, you're going to have to set the bclk to 200 (usually). The lowest memory multiplier available is x8. This means you'll be running your ram at 1600mhz (200 x8). If you get ram that is rated lower, you can't be guaranteed that it will run that fast.

I personally own the 1600 platinum set and it's outstanding. While it's only running at 1440 (180 bclk x 8), I have been able to tighten the timings to 7-7-7-18 and it's rock solid.

+1 OCZ Platinums, but those Reapers are a great deal too, if you decide to get those you could tighten up those timings a lot if you didn't end up running them at 1800mhz. It just might take you a little longer to find the sweet spot on that kit, but that is an excellent price for ram of that speed.
