New G.Skill PC4800 LA @DDR550 CAS1.5

[Kakaroto]

One of the possible improvements of the new Samsung TCCD 440 on the G.Skill PC4800 is capability of running with higher voltages. In one of my previous tests with the TCCD 431 revision I concluded that Samsung TCCD only can run with higher voltages above 2.9v in combination with a lower CAS latency.

When running CL2.5-3-3-6 the maximum voltage is 2.7 ~ 2.9v (TCCD 431)

With the new G.Skill modules I've tested the maximum voltage range at 2.5-3-3-6 is 2.6 ~ 3.12v.
I also tested these modules with CL2.0, the maximum voltage error-free is 3.2v.
Higher voltage than 3.2v is only giving me more errors.

This is not a huge improvement in voltage, with TCCD 431 I used 3.1v max.

But this is not the only improvement, I even can hit CL1.5!! This is a little performance boost, but he its CL1.5 :*)

And 2-2-2-5?

Can this Ram compete with the brute low latency power on the Winbond BH-5 chips? Well almost but it's still not good enough.

With 2-2-2-5 I was maxed out at 230MHz. Overall a pretty good result, it proved to run LOW latency and high speeds.

Test system

- Athlon 64 3400+ Newcastle (week 34)
- DFI Lanparty UT 250GB rev1.0
- 2x 256MB Gskill PC4800 LA

Benchmarks

I tested with two modules inserted, and this is what I hit with 1.5-3-3-5 1T @3V
As you see the other settings displayed on A64 tweaker are also maxed out!

With one dimm inserted

1.5-3-3-5 1T @3.1v

What cooling is this CPU........up to 2.9G

Nice CL1.5, but I think higher speed(ram) could better than CL1.5.

offcourse it is, but this is a nice test for users who cannot do high speeds like Intel or NF2 users.

This is Prometeia Mach 1 R507 cooled.

OK~~I try..
But My English not gool enough...
Use Taiwan English.. :O||:


Single Ch VDIMM:3.1V 1.5-3-3-5-1T
CAN RUN memtest STD mode ??

He's asking: Single Channel 1.5-3-3-5, Voltage at 3.1V, Does MEMTEST can be run over the STD?

Sorry, poor interpreter ;rr;

Ya....Thanks...

How about this:

With the parameters: Single Channel 1.5-3-3-5, Voltage at 3.1V, can you complete the memtest test at STD mode (or complete the STD memtest).
