Overclocking is always a gamble, especially when you are dealing with memory this fast to begin with.  That is what we are here for though.  We are going to squeeze every drop of speed out of this already fast DDR.  My results may not be typical so just remember that you are only guaranteed the rated speed of 266MHz (DDR533) at CL 3-4-4-8.

Test System
Asus P4C800-E Deluxe(1011 BIOS)
P4 2.4C
1GB PC4200 (DDR533)
GeForce 4 TI4600
120GB Seagate 8MB buffer

     The maximum settings I could get was 270MHz FSB with memory timings set to 3-4-4-8.  Memory voltage was kept to 2.85v.  As for testing, I ran the memory at 266 (DDR533) and 270 (DDR540).  The timing were 3-4-4-8, voltage 2.85v.  Memory frequency was set to 1:1. PAT was enabled and set to Turbo.  Turning off PAT had no effect on the maximum front side bus speed.  Let's check out the results.

     The memory scores just rock.  The GeIL memory almost achieved a score of 6500 points n the INT Buffer score.  6444 is still the best I have achieved using Sandra.  Let's see if the added bandwidth equates to a higher 3Dmark score.

     At defaults and overclocked, the memory helped me achieve my highest score.  When I beat my highest score at default settings, I knew I was going to break 16000 when I overclocked.  Now these scores most likely seem low to all of you Radeon owners, but remember I'm using a lowly Ti4600.

Conclusion

     The GeIL memory achieved the highest memory scores seen here at ClubOC.  However, as impressive as 270MHz sounds, it's only 4MHz above default.  I was expecting to get at least 275MHz (DDR550) from this memory.  Am I disappointed?  Not at all.  270MHz is more than most people can get with a 5:4 memory ratio and for me to get this speed using a 1:1 ratio is outstanding.  What's the price you have to pay for this speed?  $350 at Newegg.  That's a pretty decent deal, believe it or not.  The cheapest PC4200 I could find on Pricewatch was $383, so you had better act quick before Newegg notices.
