512MB Stick Hynix BT-D43 @ $105 US !!

[Rabbi]

I live in New Zealand, but if anyone would like me to send them some I'd be happy to do it.
I haven't tried any because I already have BH-5.

The RAM is just Generic Hynix, advertised as:
512MB DDR400 (pc-3200)/Hynix (Chip# HY56U56822BT-D43) - $105

Or Generic:

512MB DDR400 (pc-3200)/ Intel Certified/(Hynix Chip# Hy5DU56822BT-D43) --Lifetime Warranty! - $133

Or TwinMos DDR400:

TwinMos 256MB, DDR-SDRAM, DIMM, DDR400 (Garaunteed Hynix BT-D43) - $70

I realize you don't have the posts for the classifieds but that is the only place to work out trades and sales. You might want to get a mod to delete this.

[crimedog]

well turning this thread around slightly...
anyone know how well these chips will do with 2.9-3.0v?
want to run 229mhz 222-11 if possible ;)

[Rabbi]

wannaoc,
Just thought people were more likely to see it here.. I'm not really selling any RAM, but I'm prepared to mail some if anyone requests.

crimedog,
Any RAM with BH-5 chips will do this if you give it enough voltage.
Mushkin Level II is good.

[Capt Fiero]

I can verify that is great ram the Hynix stuff. But the price seems a bit too high. If I were you I would shop around a bit.

[Rabbi]

Thanks Capt Fiero, I didn't know what the going price for it was and I've heard it compared to BH-5 so I thought this was a bargain.
I'll probably still get a 256MB stick of the TwinMos DDR400 just to see how it goes.

[Capt Fiero]

This is CDN$$ its about 70$ USD

[Rabbi]

Capt Fiero,
Nice price!
How far have you pushed that RAM, and with what specs (voltage, timings, etc) ?
Just wondering what sort of performance to expect...

[flapperhead]

yeah u cant go wrong with a 256 stick.geil and ocz uses hand picked d43 stuff for their premium pc4200/4500. i have some generic pc4000 made from adata chips. not sure whether they are d43 or d5 chips but they run like a bat outta He** and respond nicely to 3+ volts. if u get a couple sticks how about letting me know how they overclock... thnx

[Rabbi]

flapperhead,
will do dude, I'm building a rig for a friend of mine that just wants an internet surfing rig. So I'll get her a 256MB TwinMos BT-D43 stick and test it myself before hand.

Keep you posted...

[Capt Fiero]

Mine is the D43 stuff. It was sold as PC3200 but is the same chips used on the PC4000+ stuff. I dont have enough CPU to push it as hard as it will go.

Scroll down to the bottom to see where i am sitting with it. http://www.captfiero.com/cpuz.htm The full sheet is a breakdown of what I am doing with my machine.

[Rabbi]

Hav you tried running tighter timings with more VDimm?

[Capt Fiero]

I don't know enough about voltage on ram, I am already at 2.7 if some more experienced people could let me know how much voltage is safe I will crank it up and tighten up the timmings another notch.

[Rabbi]

A lot of people have been feeding these chips 3v+, much like the Winbond BH-5 chips.

For example, OCZ GARAUNTEE their BH-5 equipped modules up to 3v, and I've seen a lot of people on the forums that give those chips in excess of 3.2v

I would be completely comfortable giving those chips 2.8v-2.9v Capt Fiero... when I start raising my FSB I'm gona make my VDimm limit 2.9v

Just a question, have you tried any tighter timings @ 2.7v?

[Capt Fiero]

I just tried tweaking thinks and I really dont know what I am doing, and it did not work. My motherboard seems to max out the ram voltage at 2.85 so that is where I set it, and it froze up when I moved everything to 2 moved moved one of the 7 down to 6 and the other 8 down to 4. I will see if I can find the thread that listed all my settings and maybe you could give me a hint on what to change.

[Speed_Mechanic2]

Most Hynix D43 will not run timings faster then 2-3-3 (CL-tRCD-tRP) above ~DDR333. It may run 2-3-2 up to DDR400, but I would be suprised if it ran 2-2-2, or even 2-3-2, timings above DDR400 with even 3V.

[Capt Fiero]

Current ram setttings are as follows

Bare with me this took some time to hand right down from the bios


DRAM CAS LAT 2.0
DRAM RAS PRECHARGE 3 CLOCKS
DRAM RAS# TO CAS# DELAY 3 CLOCKS
DRAM PRECHARGE DELAY 7 CLOCKS
DRAM BURST LENGHT 8 CLOCKS
DRAM IDLE TIME is set to auto
DRAM Refresh rate is set to auto


Which number should I move up or down. I ran memtest 86 and everything is good to go so far.

[Rabbi]

Sorry Capt Fiero, apparently those chips don't run 2-2-2 timings.
You could still see if 2-3-2-7 works for you... Then once you'v done that start reducing that 7 in one-step-decrements, but don't go past 5.

Thanks for the heads-up Speed_Mechanic2 :)

[Capt Fiero]

Well I got 2-3-3-6 and I think I am going to leave it there. I tried the 2-3-2-6 and it would not run. I have the 3 other settings, Dram Idle Time and DRAM Refresh Rate and Dram Burst Lenght that are all set to auto.

[Speed_Mechanic2]

Your processor is holding your memory back by alot :0 - Maybe someone will be in the P4 "C" market soon - 2.6C?

[Capt Fiero]

LOL, before I put a new CPU in here I am putting in a new Video Card. Then I will think about a new 800mhz CPU.

[Rabbi]

Capt Fiero,
Does your motherboard give you any more FSB:MEM ratio options that will allow your RAM to run faster than it currently is?
I have an AMD system so I'm not familiar with how much bandwidth the P4 needs, or can use, or how much of a performance penalty would result from running FSB & MEM out of sync.
Could you shed a little light on this Speed_Mechanic2?

Max your ram out at whatever the board can throw at it, 2.8 is safe cause in actual fat it is prolly like 278-2.75. I know that my IS7 needs a vdimm mod so I can go higher than 2.8 cause 2.8 in reality is about 2.75 based on what proggies show in windoze

the D-43 shines with 2.75 plus vdimm, try 7,4,4, 2.5

[Capt Fiero]

With this CPU I only get 2 choices, 266 or 333. I think that means I get 1-1 or 5/4 I am already running in 333 mode that should be 5/4 and explains why my ram is running at a faster rate than my FSB is set at. I dont think that there are more settings than what I have already posted. Like i have said, this is a learning experiece for me. Until recently I have always just tossed the ram in and been happy with more quantity. I have not tried to OC or get it to run any faster until recently. I am just happy that I lucked out and got these D43 chips for so cheap.

Wouldnt those timmings be slower than what I am at now. 2-3-3-6 is what I am running right now.

[Rabbi]

Stick to 2-3-3-6 Capt, Cisco Kid may have been running D43 modules @ much higher speed and needed to relax his timings... but you are running them below spec, so no need to do that.

[Speed_Mechanic2]

There is little to gain, and quite possibly some to lose, running memory higher then FSB. That is why it's best to get a new 800 fsb cpu ;) Though a 2.6C isn't cheap at $170-ish.
