Hynix D43 -- two different sticks ??

microfire · Sep 22, 2005

I am looking at buying a couple of PC3200 512MB Hynix memory modules, very shortly but...
Question is, both sticks have slight different numbers (see below), yet both stick end with D43.
Will they be ok, as in perform the same roughly??

Stick one:

403a
HY5DU56822CT-D43

Stick two:

513AA
5DU12822BT-D43

Yes Hynix D43 are awsome sticks. They clock very good (250-260MHz) and are similar to 5B G's from Micron, but they can't do tight timings.

Nice, so these two different D43 will work sweet together?

I am intending for the time being, to put them in my second machine in sig.
Will only be running these sticks at 175 MHz.
What will be the tightest timings possible at such low memory speed with D43?

They are both D43 chips but I'm not 100% sure if there will be any problems.

Hynix D43's simply don't like tight timings, but at those low freq you should be able to pull of 2.5-3-3-7.

Thats cool, thanks. Heres my plans...

Currently:
I have 4x 256MB sticks in the second rig.
Three different kinds of chips on the four modules. 2x Winbond PC3200, Hynix PC2700,and Samsung PC2100 (I think, that what they are).
Two modules of which, are a pair of 256MB Winbond BH-5, will take out and give the flick, since the other modules are slowing these down (I really don't like windows XP and only 512MB total). Plus I should be able to sell the BH-5 for the same price as the bargin D43.

After (when I get the D43):
Having the D43 will be a cheap 2x 512MB upgrade.
Machine will to be able run 800 FSB processor in the future and have some overclocking head room.

Confusing yeah lol

Yeah

That is a strange combination that you described above, but yes when you get D43's they should do you fine.

Im am surprised that these 4 sticks run, memtest86, prime95, and 3D stable, all at only 2.9v with good timings 175 MHz 2337.

Everest reports latency of 90ns, which is good for an Intel 865 and a 400 FSB processor.
Super PI: 32M = 43m 34s

Stick one has 16 chips.
Stick two has 8 chips.
Am I right?

These chips have two things in common:

- Manufacturer
- D43, code for speed rating. Stands for DDR400 3-3-3-x

Otherwise they are totally different chips...

- They are of different density (32x8 vs. 64x8)
- Different die revision (CT/BT)

...and most likely won't behave alike under any conditions.

Do they actually run in dual channel?

I have no idea if one is single sided or not.
Buying them from someone else, and have not seen them before.
Though it sounds like you know from looking at the numbers.
Thanks, maybe I should not buy them.
Thats why I am making sure before I pay for them (maybe get ripped off).

Can anyone else verify this?

I can't answer that question (that's why I said that I'm not 100% sure on this in the beginning) since I never used Hynix chips before but I know that they are solid when it comes to OC'ing and I seen them in action.

Maybe largon has and he could verify it for sure.

This is becoming dodgy. I found a bad photo of the sticks. One of them does look different. The chips appear to be more spaced out on the top module in the photo.

RedDragonXXX · Sep 22, 2005

Why don't you just go with some cheap TCC5's or perhaps TwinMOS BH5/CH5 (you would be taking a gamble there cause they don't guarantee which chips you will be getting).

Hynix D43's are good but I wasn't aware that those two are totaly different untill largon mentioned it.

microfire · Sep 22, 2005

These are really cheap. I haven't paid for or recieved them yet, so I can back out of buying them.
I only can afford 1GB of BH-5, the last pair (I only just brought for main rig for 2GB total) are 2.5 times the price of the modules I am looking at.

I already have
2x 256MB TwinMos BH-5 (works well in second rig, but not enough RAM)
2x 256MB TwinMos CH-5 (does not work on second rig, no matter what voltage, errors out)

I think I may just have to wait, will a couple of cheap 2x 256MB TwinMos BH-5 show up in the future, or just break the machine up and sell it.

Yeah this is not working out like I thought. Think I will pass on them.

Thanks for all of your help, you have pointed me in the right direction. Cheers.
