I just bought this from ocuk for £100 delivered.

OCZ 4GB (2x2GB) PC2-6400C4 800MHz ReaperX HPC Enhanced Bandwidth Edition Dual Channel DDR2 (OCZ2RPX800EB4GK) (its 4-4-3-15)

I have it overclocked to 1080mhz @ 5-5-5-18 2.2v at the moment, using 5:6 divider on my Abit IP35-Pro, my fsb is 450*8 so ram is a tasty 1080mhz. I tried 456mhz @ 1:1 4-4-3-15 2.2v but unfort it failed in memtest after a few mins as i ran my team xtreem 2gb ram @ 456*8 (3.65ghz) 4-4-3-4 2.2v.

UPDATE: I've just tried it with 1:1.25 divider (1125mhz) with 2.35v but that failed, i dont really wanna put anymore voltage through it as i'm a bit chicken! So my next step is to lower timings a little to find its lowest timings @ 1080mhz.

UPDATE 2: Looks like 5-5-5-12 is my limit @ 1080mhz, im very happy with this:)

In reviews it gets between 1100-1140mhz usually for 5-5-5 with 2.2v.

Btw the ram is only a little bit warm with 2.2gb due to those great heatsinks!

Also you can only use 2 sticks as the heatsinks are to wide to let you use 4 sticks of ram on your motherboard, but by the time people need 8gb ram there will be ddr4 out!

yeah, after reading reviews i was expecting to get maybe 1040mhz, 1080 is nice, i could prob get more if i lowered fsb and used 1:1.25 divider so get 1100mhz ish but the fsb and cpu would be lower so will just lower the timings instead, will be trying 5-5-5-15 then 5-5-5-12, then 5-5-4-12 and see which work. im happy to have fast ram and yet its 4gb too and at £100 its a nice price, there are MILES more expensive kits that dont overclock this much. you dont need any active cooling as the heatsinks are only slightly warm.

That's extremely nice, i'll definitely consider this along with a good motherboard and a penryn processor, my current rig is really at it's edge unfortunately :/
 
I have this Reaper X EB stuff as well and it does well on the AM2 platform too. One thing to beware of though, is that this RAM will not go into slots that are next to each other, as the heatsinks are oversized. I had to remove the heatsinks (thus voiding warranty) from my RAM to be able to use it.

The ICs on this RAM are pretty much guaranteed for 1000Mhz+. They are the same ICs as used in the 4Gb Platinum PC8000 kit, but just have the larger heatsinks.
 
most ppl have 4 ram slots, so it wasnt a problem for me. Also every review i have seen has got 1100+ mhz out of this ram so 1060 will be easy. Im really happy with my buy, next purchase will be a 45nm quad 2.5ghz Q9350.

It depends on how the motherboard manufacturer positions the slots for dual channel use. On my board you have to run the RAM in slots that are side by side to have dual channel. This RAM doesn't fit with the heatsinks on if this is the case.

yeah, been a LONG time since i've seen a board that has 4 slots that uses slots next to each other for dual channel tho, normally there is a 1 slot gap inbetween.

I want some brave person to put like 2.6v through the ram and see how it can overclock as the heatsinks will keep it nice and cool but i'm too chicken, have only seen reviews use max 2.2v that warranty permits.

Extra voltage won't make any difference to this RAM. 2.2V is enough to get it to its max clocks. There are a few kits based on this Powerchip IC out there and they all seem to do a similar max OC with low voltage. Lots of people on XS have found this out, as have the guys at OCZ in their tweaking guides.

Got a link to that tweaking guide by any chance?
