Few days with 2x1GB G.Skill PC4000HZ - full OCing report!

If there is anyone that liked my couple last OCing reports, then there is another one for ya!

2x1GB G.Skill PC4000HZ (Samsung UCCC 0537)









This time, I have 2GB kit based on Samsung UCCC - F14000USU2-2GBHZ from G.Skill. Stock is DDR500 8-4-4-3.0-1T, but I will not show you any results at DDR500 I went straight for DDR560. SPi 32M finished without a hiccup, so 285MHz was the next step... Soon after I was benching @ DDR580...

SPi32M @ 290x11=3190MHz 8-4-4-3.0-1T

Sandra @ 290x11=3190MHz 8-4-4-3.0-1T

Absolute MAX for SuperPi 32M to pass was 291MHz

SPi32M @ 291x11=3201MHz 8-4-4-3.0-1T

I also did some 3D tests as I had a chance to play with 7800GTX 512MB for few days. Thanks

3DMark2001 @ 290x11=3190MHz 8-4-4-3.0-1T

3DMark03 @ 290x11=3190MHz 8-4-4-3.0-1T

3Dmark05 @ 290x11=3190MHz 8-4-4-3.0-1T

Aquamark3 @ 290x11=3190MHz 8-4-4-3.0-1T

How about some SP2004 (GUI for P95) action?

Anything above 291Mhz was not stable enough for any serious benchmark to complete, so it was time for a little experiment --> 8-3-4-3.0-1T I only had to drop few MHz, to find stability in 32M @ 8-3-4-3.0-1T.

SPi32M @ 286x11=3146MHz 8-3-4-3.0-1T

First attempt to pass 3D at 285MHz did not seem to bring success, so I just dropped to 280MHz and all was fine and dandy from here. I'm pretty sure If I was more patient I would fight harder for few more MHz in 3D, but I don't have the video card anymore. Later, I noticed I forgot to run 3DMark05

3DMark2001 i 03 @ 280x11=3080MHz 8-3-4-3.0-1T

Some SP2004 to finish off,

But let's not stop here, shall we 8-3-3-3.0-1T anyone? The journey to stability from 280MHz was very long but I noticed some light at 253MHz 8-3-3-3.0-1T

SPi32M @ 253x11=2783MHz 8-3-3-3.0-1T

Sandra @ 250x11=2750MHz 8-3-3-3.0-1T

For 3D, I dropped to 250Mhz. As a matter of fact, those 3D runs I did when my max 32M was 250Mhz. When I did 253Mhz in SPi 32M, card was already gone... So, maybe that 253Mhz could be 3D stable as well...

3DMark2001 i 05 @ 250x11=2750MHz 8-3-3-3.0-1T

3DMark03 @ 250x11=2750MHz 8-3-3-3.0-1T

Some SP2004 action

3 hours SP2004 LargeFFT 1770MB used @ 280x11=3080MHz 8-3-4-3.0-1T

As you probably noticed, vdimm I was using was 2.6-2.7v. This is exactly ALL those sticks needed for proper operation in all those instances. Anything higher would not net any gains, though. CAS2.5 as well as 5-2-3-3.0-1T @ DDR500 is NO GO!

What I liked about those SAmsung UCCC based modules is it's flexibility- from 8-4-4-3.0 to 8-3-3-3.0. Also, modules run very cool and probably fan is finally not required. I had one blowing, though. But that's because It's always there, no matter what memory I use.
As far as average results... From what I have seen so far (results from AndreYang, Major and few others) modules I had seemed to be performing exceptionally well. But set your expectations a little bit lower to avoid any dissapointment in OCing. But so far we've seen results as 275-285MHz. Considering the practical usage of 2GB kits at this moment (gaming and everyday use, not benching!) it's a pretty good choice, especially that it's price is very attractive.

I hope you liked my new report

This kit was sent to me by G.Skill. I was assured that it was not hand-picked before shipping it to me. It comes from the same batch that is available in Retail. I'm not associated in any way, shape or form with G.Skill. I was simply given this kit for evaluation and desided to present my tests regardless of performance. The results I obtained may or may not be on par with all other 2x1GB G.Skill PC4000HZ kits available for purchase.
