Seriously good RAM

This stuff already has enough positive feedback here, but I thought I'd add mine to the list :)

I just had one module fail - after 4 years of being used pretty much each and every day. Absolutely solid RAM, fast, and damn good value for money. I recently added another 4GB kit, so at least I still have 4GB to play with! :)

Will definitely be getting another kit ASAP - you can't say fairer than 4 years of faultless daily use for this kind of price. I wouldn't dream of buying anything BUT Kingston Hyper-X :) It really is that good.

I've had 4GB of this stuff in my system for 18 months. It's performed flawlessly (I've reached uptimes of 90 days), which is more than can be said for the Corsair and OCZ equivalents, both of which were finicky. You can't ask for more than that.

Excellent RAM

I've had these installed for well over 2 years I got them from here for

Does what it says...

if you cant afford (or dont need) the latest spec, then this is whats right. i was quite busy last week so i just put it in and left my motherboard to do the AUTO work, not got the right timings yet but i bet it can easily do it. great ram, easy upgrade, fantastic service (as usuall)

Daniel 2011-02-02

Very happy

This is the most reliable ram i've used so far. Got 2 sets of these for running 8gb and has been the only ones so far to not give me any problems.

Highly recommend

Good one

I'm very pleased for buying this RAM, even when I'm unable to overclock my motherboard to have it on 1066 FSB it still makes my system lightning fast - no more waiting when switching to the taskbar from resource-heavy game like Mafia2 etc.

Overall, does exactly what it says on the box, good buy :)

Good Heatsinks

Decent RAM, the modules are double-sided and the heatsinks do a good job dispersing heat build-up.

Kingston HyperX's currently running CAS: 5: 5: 5: 15: @ 1066MHz for 2.2v (Memtest86 stable overnight), I can recommend this memory.

Powerfull bit of kit

bought this HyperX 8500C5 kit to replace my Corsair XMS2 6400C4 4gb [4x1gb] kit, as needed more overclocking headroom and less strain on the Phenom II x4 955 IMC....and WOW do these have the headroom! ;-]

fired these up at 1066 to begin with, all stock settings ie voltage, timings etc. and were a bit faster than my corsair XMS2 800's, BUT.... bump the voltage up from 2.2v to 2.35v and i have been able to keep them running 100% stable at 1159mhz! AND also have been able to tighten the timings even more, 5-5-5-15-17-2T , while also having the 'Four Bank Activate Window' set to only 16 rather than the default 20/22 :-]

the heatspredders on these kits are very nice, not only do they do their job very well, but they look pretty damn cool aswell.
like someone else said in their review, you cant really get a good idea of how good these look in that photo above, they look amazing when in your hands

yet another amazing bit of kit, and yet another amazing service and delivery from OcUK :-]

Got this RAM about 2months ago and its rock solid! Fastest ddr2 RAM ive had so far and a big improvment on my system. Getting another 4gb of this stuff soon, got this runnning with Win7 64-bit Pro and my system needs another feed of this stuff =)

Also this looks alot nicer than in the picture, i was abit iffy about the look of it but its looks really sweet in hand.

Well recommended for any DDR2 system! Again another good service from OCuK! 5*

Set the bios with my old ocz 2gb still in 2.2v 1066 5 5 5 15 and the rest on auto switched off then popped the whole 8GB in that I ordered.
Up and running straight away without any problems.

good memory

this is great memory i have it running at 5-5-5-15 @ 2.1volts 1066Mhz cant complain at that to be honest.

will be getting more of this ram at a later date

also it looks better than in the picture well recommended

paul 2009-09-12

Great Stuff

Works brill, havn't tried oc'ing it yet but feel there's really no need for it. Works perfectly at 1.8v @ 5-5-5-18, havn't tried 5-5-5-15 as i would prefer the lower volts over a wee bit tighter timings. Excellent buy.

Ok once u work it out

Well I got this ram when I redid my P.C ( M4N82 Deluxe, AMD 955BE, V8 cooler master and a few over bits ) and was hoping to OC with out any problems. I got my Processor upto 3.8 and my HT on mobo above 2.4. When it came to getting what I could out of the ram every time I went passed 1066 Mhz I would BSOD or insta memory dump. In the end tho I got it to OC afther playing with Volts and timings. Over all I do rate this ram as good the only reason I have not give it 5 out of 5 is the trouble I had getting it to OC. Once I did get it to OC tho I manage to get 4Ghz from the AMD 955 2,5?? from the HT so all in all was not a bad buy.

Dark Earth 2009-08-14


Great ram, could only run 2gb at first in Windows 7 without crashing on boot but altered dram voltage to 2.1v and booted perfectly, rapid :)
