GSKILL is doing great business lately with hard-core memory solutions. First the PC4400 1GB/512MB modules based on the famous Samsung TCCD chips and now the PC4800 series.
The PC4800 is build with the new revision Samsung TCCD 440 cycle chips. These chips yield better speeds to achieve the PC4800 (DDR600) in Dual and single channel mode.
Soon the 1GB PC4800 modules with also be released by GSKILL.
The NEW Samsung TCCD 440
The "possible" improvements:
- More flexibility with higher voltages. (range 2.5 ~ 3.0v)
- Better yields, lower voltage at rated speeds, means higher overclock capability
- Works better with CAS2.0
Enough intro, let's show the pics 8) :
The package:
Test system
- Athlon 64 3400+ Newcastle (week 34)
- DFI Lanparty UT 250GB rev1.0
- 2x 256MB Gskill PC4800 LA
Unfortunatly I still do not own a Dual channel S939 platform. Begin next year the MSI Nforce4 board will arrive, so I have to it with the DFI.
Like most of the people already known, testing TWO dimms on DFI with S754 memcontroller is a shot in the neck.
I could not get 2 dimms working, even at default rating speeds/settings. I don't know why, cause I got it work on my 2x 512MB GSKILL modules.
Anyway, one dimm is the only way to test these modules.
The Benchmarks
First I tested both modules seperatly to look what those babies can do.
Module 1 (marked with a one):
Module 2:
DDR600 2.5-3-3-6 1T 2.6V (module 1)
Piece of cake for this ram, who needs 2.5-4-4-8 :*)
DDR640 2.5-3-3-6 1T 2.9v (module 1)
No swet, now you see the improvements of Samsung 440, it's reacting well with higher voltages.
DDR660 2.5-3-3-6 1T 3.0v (module 1)
Again, 3.0v works on the TCCD!
This is even stable in memtest86++ _/-o_
DDR640 2.5-3-3-6 1T 3.0v (module 2)
The other module (2) performed a little bit lower than module 1, logic it would be very lucky to get two modules perform the same.
Unfortunatly this module does not respond well with 2.5-3-3-6 1T @DDR640. At DDR600 ~ 620 it barely run well with these timings.
With 2.5-4-3-6 1T 2.9v it run fine, Trcd 4 instead of 3 is about 20~25MHz loss.
Conclusion
This ram is definitly tha bomb! :7 Can do very high speeds, even higher when losing some timings.
It can also run on 2-2-2-5 timings with lower speeds (200-240MHz*)
*Upcoming test.
Pros
- Very very cheap, around $130-150
- Contains new revision Samsung TCCD
- Clocks like hell
Cons
- Still does not work well with two dimms on S754 platform.
