5* Brilliant Overclockable Memory

Okay so this is my second review, had the memory for 3 months now without a single problem. I got brave and decided to do some overclocking and they are brilliant at that. Both sticks are now running at 4-4-4-12 and i've been able to increase their FSB's from 400 (800FSB) to 450 (900FSB) stably with no problems. -Note- i've left my Memory voltages set to Auto, so if your not able to I don't know what voltage you would need to set to achieve this manually. But yeah amazing overclockable Memory
5* Built PC with slightly higher budget and this flies!

Bargain, Definetly Memory worth buying.

Only had the memory a short time so not sure about reliability yet, Easy to install though, looking else where people have claimed it will do timings of 4-4-4-12 by increasing voltage to 2.353 but i'm not risking it and set it manually in the Bios to 5-5-5-12 which runs stable and does the job.

The memory alone has allowed me run Far Cry 2 fine on very high 1280x1024 settings, instead of on normal 1024x768 settings i had to resort too previously.
5* Very Good

Excellent memory, sturdy, fast and you dont get that, "oh my god, am i going to break this" kind of feeling when you install it.

5* Brilliant Memory, Very Easy to Install
Reviewed by Stephen on 28/12/2007
I previously bought a pair in June when I was building a new computer and they have performed faultlessly and proved very reliable and fast.

I have now just bought another pair to bring me up to 4GB due to doing a lot of heavy graphic and video work and again I am very impressed. What more they are now half the price from when I got my original pair. They are so easy to install that I showed my eight year old how to install them and then watched as he installed them with no problems at all. He now wants us to buy parts for the two of us to build his first computer.

In my Vista system my memory scores 5.9 in the Windows Experience Index.
