GSKILL PC4400 TCCD at CAS2.0

[kakaroto]

I read the topic about high voltages on TCCD memory, so i tested with CAS2.0. And it worked!!

It seems that the TCCD memory dont like high voltages with high timings, i get lots of errors with CAS2.5 @3V and zero with CAS2.0 @3V.
So lowering the CAS latency gave me the oppertunity to play with more Vddr.

Great discovery i guess..

Here some screens with info 2-3-3-7 3.0v

have you try with CAS 1.5 or CAS 1 ?

My PC2700 noname ,go up more with CAS 1.5 or CAS 1 ,i don't know why ,but it go over 270 with 1.5 and only to 263 with CAS 2

[Playful_Buffalo]

Nice! did more or less voltage effect the Cas2 at those speeds?

[Geforce4ti4200]

too bad cas latency does not matter on a64. My friend rukkor sure will be supprised though, he says no ram will do cas 1.5 over 166fsb. what I really am interested in, has anyone gotten ras-cas1? like 2-1-1-7 timings?

This guy hasn't got a clue lol

And this guy does....

If cas doesn't matter then why does everyone strive for cas 2 on A64...

Riggghhhttttt....

Actually cas2 or 2.5 really doesn't matter on my DFI. I've tested cas2-3-3-5-1t and cas2.5-3-3-5-1t and noticed no difference. If anything 2.5 actually gave me higher 3dmarks. Of course maybe my DFI doesn't take advantage of cas2.

I have some bh-5 chips coming on Tuesday so looking at some 270htt 2-2-2-5-1t action to compare with.

kakaroto you are so lucky, have best BH5 I ever seen, now these superb TCCD; congrats m8

I found I lost a chunk of bandwidth at CAS2.5 with my BH-5 on a k8N neo (at 1T) and was the diff between smooth and jerky in some games

My DFI won't evem boot @ 2.5!

no.... you didnt, it may just seem that way but u didnt lose a chunk of bandwidth

I'm using my bh5 @ 270 1.5 2 2 1 7 12 1T in dual

[Firelord-OCHW]

No because I didn't test it to make sure that it didn't make a difference so I could just come out with BS!

I did my testing (SANDRA, AIDA32, 3D'01SE and 3D'03) and there was deffinetly a noticable difference in all.

So yes I am right thank you

[Jack]

kakaroto, is your mem stable at 260MHz or is it just screenshot stable?

and what kind of bandwidth are you getting at 260MHz 2-3-3-7?

great find tho'

[Ubermann]

My TCCD does 275 with 2-3-3 at 3.5 volt.
But its only cas 2 that like that volt.

With my BH5:

AN50R cas2.5 to cas2 yields NO difference
K8NS cas2.5 to cas2 yields NO difference
K8NS Ultra939 cas2.5 to cas2 yields NO difference (Except cas2 gives higher clocks)

A lot of ppl have confirmed that cas2 or 2.5 makes no difference in performance on A64. Are you sure you diddn´t change any other settings? Same thing with Intel P4 actually. VERY small/No difference.

So yes I am right thank you

LOL

You should try to be a bit more humle. No one likes a smartass.

[kakaroto]

more voltage gives better stability with CAS2.

hahaha, your very funny guy! 2-1-1-7. You can be to optimistic about TCCD.
A64 do like low latency, especialy in 3dmark and superPI/Pifast.
The differency is not much, but he thats the purpose of tweaking dude.

260Mhz is just some screen yet. with 250MHz it get 0 errors in memtest, but 255~260..10K..maybe it need some higher voltages...

My TCCD does 275 with 2-3-3 at 3.5 volt.
But its only cas 2 that like that volt.

Woow thats awesome, try some higher voltage then. (I still using the 3.1v bios of the DFI)
What is the 24/7 voltage limit of TCCD?

[$0m#0n#]

I think 3.2-3.3V?

[YoupY]

I've tried the cas2 setting myself but I got only like DDR500 Mhz with 2.85V. (2.0-3-3-7-1T-DC). Since I've got the 437 TCCD ships on my GSkill this may not work as wel for me as it does for Kakaroto.

After that I tried runnning @ cas2.5, also with 2.85V and timings set at 2.5-3-3-7-1T Dual Channel also.

That got me this result:


*Clickable*

So maybe the 437 chips like cas2.5 and high volt better

Can anybody confirm this??

[krampak]

I get higher clocks at 2'7V than 2'85V.. now 280 2'5-3-3 1T at 2'7V wich gives me 8K mb/s.

PD: Geil Ultra X PC3200, unknow TCCD revision.

[LANjack]

Can we get some good pictures of the chip numbers

he's simply right.....it doesn't effect apps nor games more then 1-2%....

[kakaroto]

these are the modules:

[LANjack]

431 and F as I suspected!

Thanks for the photos and confirmation.

[kakaroto]

today i tested with 3.2v and higher, it gave me NO improvement.

250MHz 2.9v 2-3-3-7 = 0 errors in memtest
255Mhz 2.9v~3.3v = 10000 errors in memtest

Controller problem? i think so...

[bacon]

cool, just ordered some of this kit from excaliberpc.com

Should be here by end of week to me in the UK

was guna get some OCZ 4200 but in Uk will costa bomb and excaliber wont sell it to me with paypal as its $2 over the limit and not paying fees for a transfer

So got some Gskill coming at £178inc (same price as crucial ballistix (sp) here in the UK)

Dam cheap hpefully get good uns
