New Gskill Pc4800 La @ddr660 1t

[kakaroto]

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 will 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. At the beginning of next year the MSI Nforce4 board will arrive at my doorstep, so I have to it with the DFI for now.
Like most of the people already know, 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 sweat, 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.

[Super strokey]

impressive mem there

[Cyrus The Virus]

Any Idea when it is released ?? Like in the netherlands ?

[Mrki]

nice results but 1x256 or 2x256 are not longer interesting i think ...

[drunkenmaster]

the euro stores in norway i think, and germany maybe the other one, have it listed for 2-3rd weeks of jan for stocks. 256 sticks though, i think, my euro language skills apart from english aren't the greatest.

[kakaroto]

Have you tried DQS Skew of +64 and +128 with 2 sticks? Or anything else?

Also tryed any different drive strengths?

Can make ALOT of difference.

I tryed everything with the Skew, nogo. It is the memory controller or the board that is holding me back.

nice results but 1x256 or 2x256 are not longer interesting i think ...

And why isn't it interesting? 2x256 is still the best solution with benchmarking, you should know.

Testing one module give a idea how your ram performs. And this the 512LA kit.

[Mrki]

For take WR or only benches 2x256 are sure better!

But for the games today you need 2x512 ...

agreed, useless except for benching.

[xgman]

When available in USA? 2x512?

[wicktron]

I'd love to see some 2x512 OC'ing action on S939.

[Zeus]

Great stuff m8!
Where'd you get that from?

[confuzzedintel]

i would like to know where i can buy thoes in the usa?

[Onepagebook]

I am waiting here for your 939 rig and beat my 2.8v DDR650 2.5-4-3-5 "dual channel"

Nice, very nice result.

OPB, you get that result on the NF4 MSI K8N Neo4?

I am mad now..
here you go

[Reflex1]

you can get the 2x512mb version here in the Netherlands on the 3rd week of 05.

[althes]

they look very nice

Anybody know when the "LA" will be in the USA?

[Ref]

How high can you gen with 3-4-4-8 1T ? and 2T ? Awsome memory

[quicksilverXP]

I agree.. I need 2x512MB.... even at 330 MHz dual channel... it will still struggle in Far Cry.

[Geforce4ti4200]

Not supprising why they clocked so high, its 256mb single channel and he got reeeeeeeeeal lucky with one stick and his ondie controller. Id like to see two 512mb sticks run over 275fsb T1 in s939. ondie controllers almost always limit ya before the ram too. This is good stuff still, maybe with a venice or fx55/57 we could see 275 to 300fsb dual channel T1 command at 2.5-3-3-7

[MrQ3W]

Every other post you do Geforce4ti4200 you complain about the A64 memory controllers, perhaps you should get a Dothan?

[Bennah]

Nice eye candy, but im not that impressed really.

BH-5 is still king for me. Top 4 on 01 orb use Mushy 3500 BH-5... Just the stuff Ive got. Not as good as 260+ 2-2-2-5 but it can still do the bussiness.

BH-5 for me till I get my hands on some OCZ VX and try that for my self

Wait for your VX

My LA only test in neo4
