New G.Skill PC4800 LA @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

this might be usefull for users who cannot go high HTT or FSB.

Nice cant wait to see the 512 mb dimms

Hehehehe....
Yeah, my 512mB kit of G.Skill LA hit's nearly 240, sPi Stable...... 2-2-2-5

Damn, LA's are really that much better than the LE's. Where can you find 1GB kit of LA's?

[the.m]

V nice indeed, I wish thie Gskill was more available in Europe.

[spinboy]

Yeah seriously, where can you find 1 gb of LA?

[abstrakt]

I checked every site on their where to buy list a few days ago and only www.oc-wear.de had them in stock I think.

Yep nice indeed

Did you buy them from OC-Wear?
Because I ordered 1 gig kit (PC4800 LA)last week at http://www.pc-tweaker.de, but still haven't received them. NO mail that they were shipped either.

Do your sticks have an orange label on top of the package, saying "DDR600 -2.5-4-4-8" ?

[abstrakt]

Jupiler it's Christmas/New Years.. Not a lot gets shipped :/

[the.m]

Yep nice indeed

Thanks ordered, when are they gonna start taking credit cards in that country, bank transfer is a pain in the UK.

IIRC according to codered cas 1.5 set in A64 tweaker doesnt actually change anything, thats why it has a * next to it. i think thats a setting that must be set low level in the bios, not from within windows

This is set in de bios Every setting in A64tweaker can also be set in the bios.

for those who forget to turn command to 1T rather than auto
