Change from Bh-5 to some other memorys?

[Guest twilight]

As you all probably know by now i am having problem running my corsair bh-5 sticks above 220 mhz bus speed when using both 256 sticks.

 

I am about to uppgrade to a DFI NF3 mobo with an AMD 64 3000+ cpu and are not sure that my current sticks will be able to OC any good an such a system.

 

I have looked at some different memorys and got wery interested in 2*256 mb of Adatas 600 mhz memorys.

 

A couple of questions:

 

1. Is that a good choice of memorys for the UT 250 mobo, or is there any compability problems?

 

2. Can i run these sticks in dual ddr?

 

3. Is the memorys are rated 600 mhz, does that mean that they can run in fsb 300 and isnt even overclocked?

 

4. Is there any drawbacks? lousy timings or something? I dont see many people use them but they must be super for overclocking, and dont cost so much.

 

5. Whats best: two 256 mb sticks in dual ddr or one 512 mb stick?

One of your Corsair sticks must be must be faulty? Maybe

give MemTest86 a try and see if that is the case. One stick

at a time.

 

Is your 3500 Version 1.1? It should read so on the label

that is on the stick.

 

DFI 250 UT does great with BH-5 DDR but sometimes

the pcb that it is mounted on by different vendors and

the SPD values that are programmed to it has caused

problems. ala the Infinity Mboard.

 

One thing...... the DFI does the Happy Dance with

the Samsung TCCD memory chips. I'll go find a link to

a list of different memories that are using these.

 

The DFI 250 UT is a Single Channel DDR system. No dual DDR

here. That option is on the S939 Mboards.

 

Browse thru this link and look at all the different memory

flavours that DFI has checked out on this 250 UT:

The DDR that you are refering to in the above is pretty

much designed for Intel systems. The timings will be so

loose they will scare you and it will take 300+ FSB to

make up for the performance loss instead of running 250

FSB with tight memory.

Aha....so i can buy just one 512 instead of 2 256mb then, thats good to know. Both my Bh-5 can run in 255 fsb cl 2.0-2-2-2-11 cpc of but only if i run one at a time, and they are v 1.1.

 

I have read somewhere that A-datas PC 4600 & 4800 has Samsung TCCD chips, can anyone confirm this?

[Popcicle]

Okie-Dokie.......

 

Tried to post the Link concerning memories with the

Samsung TCCD chips but the Link failed to work.

 

So I'll pass along to you where I found this list and

you'll have to go there as a direct read.

 

It's at Xtremesystems.org..... Xtreme Overclocking Forum....

and the thread is titled RAM with Samsung TCCD chips (List)

posted by The Runner. It's on page 1.

 

Also on page 1 is an interesting Thread posted by OSKAR_WU

concerning memory timings etc that may help in the try at

300 HTT with the 250 UT.

 

I see the problem with your Corsair. Corsair made the

Version 1.1 available 3+ years ago. At that time we didn't

really have Dual Channel DDR boards because the Nforce2

boards had just started to hit the streets.

 

So it was a hit and miss whether 2 sticks of anything would

play together in DC.

 

Later on down the road.... twin pax became available and

these are hand tested to be compatable as a pair.

 

I wouldn't necessarily give up on your sticks of BH-5 with

out testing them first on the 250 UT because it's a single

channel memory situation.

 

Cheers.

Im using adata: smyself and cant confirm about the "lousy" timings...

Cause im able to run 290 at 1t 7-3-3-2.5 -12-14 -... at 2.9volts

 

ok if you compare to bh5 which can do 5-2-2-2.0 at 250 then

ofcourse the timing is lousy.. but then again no bh5 does 290 at any timings....

and with a little slackier timings theyll do 310 1t 10-2-4-2.5..

 

What i found out comparing my old bh5:s against this adata vitesta ddr600 was... 4000 mb/s against well.. 4750 mb/s in sandra mem bench and 500 points more in 3dm01..

 

So it seems that nf3 250gb doesnt need those extremly tight settings.. opposite to for example nf2 systems..

 

Dont know about "The DDR that you are refering to in the above is pretty

much designed for Intel systems."... ill think the design works extremly well on AMD64 boards too...

 

oh and yes the chips in vitesta ddr600 is samsung tccd:s..

O.K. I'll concede that mabe I didn't post this the way I

should have. Because if the Adata 600 is TCCD

it darn sure will run 7-3-3-2.5 for you. And this goes along

with my reference about the TCCD doing the Happy

Dance.

 

So much of the memory out there today that will give

the super HTT's are based with Hynix (etc) chips darn

sure won't run 7-3-3-2.5. Agreed. there are always

exceptions 'cause nothing is written in stone in this

business. The Hynix 5D's are pretty good stuff.

 

I'll stick by my guns tho on my thoughts about PC4000

and above being built with Intel HTT systems in mind. True

we finally have AMD Mboards now that can use this stuff with

with its HTT systems.

 

I have a couple different flavours of BH-5 that will run

260+ HTT on my 250 UT Sista. All I have to do is throw the

juice to them. And they'll run pretty darn tight timings. I

won't get into a shooting much with anyone concerning

benches 'cause there's too many factors involved. So in

this case a person wouldn't have to necessarily have to

go looking for (and spending $$) for RAM that will run 300

or so HTT to play in the same ballpark for equal or so

performance with benches etc.

 

Sure.... it's nice to be able to post high HTT #'s as it looks

good. I like it too.

 

My favorite memory presently with my 250 UT is Pqi 3200

Turbo. Has the TCCD chips and spec'd at 5-2-2-2. These

are the same chips used on Pqi 4000. So all I have

to do is loosen the timings to 7-3-3-2.5 and they run 290+

HTT and never look back. It all depends on what I want

to use these sticks for....

 

It all comes down to what makes you smile...... and

preferences.

 

 

Cheers!

Ok....then maybe the pqi turbo mems would be something to try.....it looks like 280-310 mhz bis speed isnt something unusual today with AMD 64/Nforce3 systems and my corsair can never reach that speeds, so changing memorys is a must for me.....the only question is what mems i shouls buy!!

[DAMAUL]

ok.. popcicle.. now I got what you meant...

 

and totally agree with you i must...

 

to twilight: go get some tccd: s, you won`t regret it.

 

Cheers, happy tweaking!

Let me throw some more confusion into the mix for you

on the memory scene.

 

The secret to higher HTT right now is to find TCCD that is

mounted on the Brain Power (brand) PCB. Rather than

just the regular JEDEC Reference Design PCB.

 

There are two versions of this PCB.... B6U808 and B6U815.

The 808 is the better of these two.

 

This PCB is usd by OCZ on their 3200 Rev2 with the TCCD

and is used by PQI and G.Skill.

 

Remaining vendors Corsair, Kingston, Geil, Mushkin, et al

are using the JEDEC Reference PCB.

 

Residing in Euro do you have access to G.Skill memory?

 

Please go to the website and read the thread I posted

about above. There are posts in that thread by many of

the guys from Euro and you will find it interesting. They

have posted links on where they get this G.Skill online.

 

Here in the U.S. the PQI Turbo is available at NewEgg but they

don't have international shipping. NewEgg gets $128 USD

for 2 X 256MB. One 512MB stick is comparable in price.

 

The G.Skill is available now I see at eXcaliberPC and they

do have international shipping. The PC4400 with the good

timings and the good PCB is $144 USD for 2 X 256MB. One

stick of 512MB is also comparable in price.

 

Don't give up M8..... ther's always hope.

Oohhhh....my head starts to spin soon, Fsb´s, Pcb, TCCD, HTT...i read at Anandtech that these memorys was good on the UT 250 mobo: OCZ3700EB, but they are impossible to find i guess, also OCZ 3200 El platinum rev 2 reached 308*8 and thats a quite nice overclock.

If i get this right i need a memory with TCCD chips, brain Power PCB and i should be able to reach a high fsb (if the cpu alows it)?

 

Thank you all for all your replies, now i am off to look for TCCD sticks.

 

Feel free to post some memory suggestions you know works good, and have TCCD chips.

[Guest twilight]

I have looked at extreme systems again and it seen like the A-data vitesta 4800 actually IS TCCD, ..... also 4500 is TCCD but 4000 appears to be hynix.
