DDR2 RAM
Without high-frequency ram you won't be able to overclock your intel core2 or socket AM2 athlon 64 CPU far. As this labs test shows, you don't need to spend a fortune on DDR2 RA to achieve great results.

Verdict: Good value and reasonably overclockable
Team Group is a Taiwanese manufacturer of computer components, principally memory devices. Despite its relatively unknown status in the UK, the company has been around for 12 years. It's odd then, that in over a decade, it hasn't realised that the words 'team' and 'group' have the same meaning.
Team Group, like most manufactures of performance hardware, seems to have embraced the policy of naming its products with curiously misspelled variants of the word Extreme. In this case, we have the Xtreem TXDD2048M1000HC5DC, which, rather than being Xtreem (whatever that is), is actually pretty normal, as it's rated to run at up to 1GHz at slow 5 - 5 - 5 - 15 latency timings. As with all of the PC2-8000 kits we tested this month, we had to run this kit at 889MHz and 800MHz in our Core 2 and Athlon 64 test systems, as it isn't possible to run the RAM at 1GHz at the CPU's stock clock speed.
By increasing its voltage from 2.3V to 2.45V, we were able to overclock the memory to 1.12GHz, although it refused to overclock any further, even after we increased the latency timings to 6 - 6 - 6 - 18.
Although this is a very cheap PC2-8000 kit, it isn't particularly fast, nor is it the best overclocker.
