whats the best for me? G.SKILL LA or LE

[Gaz123]

I have a DFI NF4 DR and a amd 3500 64

so can you help please and tell me why

gaz123 :banana4:

[Torin]

Do you play games or just bench?

For 2x256mb (benching) go for 4800 LA.
For 2x512mb (gaming) go for 4400 LE.

Gaz123, YGPM..but I said samething as Torin did.:D

[Gaz123]

well i just want the best and i am after 1gig of ram.
best all rounder would be good.

gaz :banana4: 123

[Torin]

1GB, definitely PC4400 LE.

[Gaz123]

cool thanks just has i was thinking to before i knew about LA.

but my place dont have any LE in stock atm dont know if i can wait.

i have to think about it.

gaz123 :banana:

[VetteTheHeretic]

is LA availible in 1 gig kits?

[Gaz123]

is LA availible in 1 gig kits?

yes it is

gaz123

[Torin]

Yes but it's only rated to run at PC4800 in 2T.

[Gaz123]

Torin is there some thing eles i should look at maybe,i was going to get some gail utra X before i seen the G.skill.

Why is LE to be preffered in 1GB kits?

LA is technically speaking better ram..

[Torin]

LA is only rated to run 2T at the high speeds in 2x512MB. In 2x256MB it can run 1T, but the performance loss you get running 2T with LA and 2x512MB, you are better off with LE running 1T at high speeds.

And no Gaz, G.Skill is pretty much the best TCCD around.

[perry_78]

Ok GSkill...

I don't quite understand the reason behind rating the same memory at 2 different "T"

What is 1T and 2T exactly?

[Torin]

1T and 2T refer the command rate, or CPC (command per clock). Running the ram at 2T compared to 1T will decrease your memory bandwidth because of how the memory controller processes information with the different command rates. This is a very simple explanation, but it is generally a universally accepted thing that 2T decreases memory bandwidth, thus decreasing performance. 1T however stresses the memory controller more, thus reducing your memory overclock. However, the difference in bandwidth between higher clocks at 2T and lower clocks at 1T usually always shows that 1T, even at lower clocks is a better option for max performance. Someone I'm sure will pipe in with a more detailed explanation. :)

mhm, no :)

Both series, LA & LE are rated 2T. Personally, i would go with LA, since the new LA package is rated 2.5-4-4-8 @ PC4800 (instead of CAS 3, as stated at g.skill's website). You might score better with these.. 437/440 Samsung TCCD chips.

[Torin]

Think what you want, but go read OPB's threads on LE and LA, and you'll see he says the exact same thing. Scroll up to the top where he agreed with my simple recommendation....

LE is rated 1T at PC4400, LA is rated 2T at PC4800. OPB will confirm this, regardless of what G.Skill's website says or doesn't say.

oo, it's getting interesting.. :) Hmm, i'm rather sure LE is rated 2T @ PC4400.. Going to check this once more, again..

[Torin]

Honestly, I won'tthink LA 1g kit will better than LE 1g!
LA 1g was tested under DDR600 2t at that time but LE was tested under DDR550 1t:)
That's all I have to say. :p:

[c42]

As stated above, the LE kit will be your best bet in 2x512, LA in 2x256.

[Onepagebook]

who tell you LE is rated as 2t...:slapass::D

[Jupiler]

LA is rated 300Mhz, 2T, not the LE.

[perry_78]

Still seems idioitic to rate the same branded memory (LA) at different command rates, depending on the amount of memory. Makes no sense to me :(

Now I'm stuck with the LA's, just hope they do DDR600 1T otherwise it will be quite fun for oc-wear.de...

[Vincentvega18]

so are they basically the same thing? b/c some le has been making 300 1t does that mean theres a possibility of 300 1t on the la's (but not guaranteed). My head is basically spinning now.

[Torin]

It is possible to get 300 1T on LAs, but in 1T, LEs have a better change of getting higher speeds.

Simply put, LEs are better for 2x512MB, LAs are better for 2x256MB.

You mean factory tested, or user tested? ;)

Bwah, come on.. :D You picked the right sticks, no doubt.

LA 1GB => LE 1GB.

Indeed, it sounds quite idiotic. That's why i believe sticks are rated 2T PC4400 & PC4800 both. It wouldn't really make much sence the other way. Although you can't find direct specifications on LE (CMD rate) anywhere, but LA are 2.5-4-4-8 @ PC4800 2T for sure. Is there a price difference between LA & LE?! Well, i've been picking some nice TCCD RAM for a long time, and i've observed many reviews & cases of G.Skill's production. Actually, hitting 300HTT 1T with LE is a rather serious task & hardcore duty. Only if your lucky with DFI NF4 + good A64 on-die memory contoller. It's just that people have been buying LE all the way, so they are confident in some way of this PC4400 series. But when the matter concerns 2x512MB (1GB) PC4800 LA, uhm - little information known. I've only seen OPB's 300HTT 1:1 screenshots of 2x512. LA is technically rated higher than LE and lower CAS. So apparently, you might score better with LA for sure.

[Torin]

Whatever testing is done to determine what it's rated for on the little label they stick to the ICs...

[Onepagebook]

You mean factory tested, or user tested? ;)


if you are talking about user test, then we must change the sticker everyday.;);)
you might wanna ask amd or intel to get more boxes too.:D

@ OPB:

You wrote here one day that your current legendary 1GB LE sticks that you are using were originally RMA'd. Which TCCD 04xx are they? Thanks! :)

[perry_78]

One thing strikes me as funny.

In SPD, the 1GB kit of LA's is 2,5-4-4-8 @ DDR400 What IS up with those sticks? They run DDR400 2-2-2-5 without any issues, why is the SPD different then?

DDR600 is something wack as well, i think it says something like 3-6-6-13.

This is all on a S754 MSI K8N Neo which i used for testing at DDR400 only.

just to prevent compatibility issues. who cares about SPD anyway.

[perry_78]

Ok the pictures are up. SPD is still pretty amazing. 3-6-6-13

[neokenzo]

If the LE uses PC4400 at 1T, wouldnt the LA be able to do the same at PC4400 speed as well?

[charlie]

LA work just FINE @ 300+ 1T :D

[Bennah]

Nice result Charlie ;)

[Torin]

Keep in mind the contention here about LA charlie is running 2x512mb in 1T, not 2x256mb like yours are.

It's 0437!
I remember , the customer said that not even stable or can reach 260 3-4-4-8..:)
On the DFI and MSI NF4 can both do over DDR600 2.5-3-3-6:D

OPB

[enzoR]

Lol :d

[Dumo]

Gskill LE all the way :D

[perry_78]

:toast:

Yeah charlie!

[Gaz123]

thnaks you all for the help but i have gone for the LE now has i was in 1st place.

thanks all

Hi OPB....finally I have my gig pc4800 LA.

I can confirm now (from first quick test) they pass Goldmemory test
300 2.5-4-4-8 1T on DFI nf4 SLI-D
305 3-4-4-8 1T (same mainb)

Other test to come...;)

[jack_tung]

This is The DDR550 2.5-3-3-7 SPD.
But This is very critical Value to memory.
If I write this spd value,most of all motherboard can not boot.
It must be by manual method.
This is the reason why I write 2.5-4-4-8 SPD Value.

I will write the 1.51 edition(Pattern 5 & pattern 8).
Because I know some-user like Only run 5 and 8 24 hour.
