DDR3 IC thread

The BBBG will boot on the M6E PSC 2400 1.65v profile (8-11-7 timings) but they need 1.9v and can't boot into Windows.

[Don_Dan]

Can you post a pic of the stick's label?

Can you post a pic of the stick's label?

There they are, mixed with all my other recently acquired 2GB sticks:


The model# is AX3U2000XB2G9-2X.

[Shiranui Gen-An]

I will say, these BBBG sticks do not like a lot of voltage. Setting 1.85v or higher and they either won't POST or will fail to load Windows. Even using eventual voltage, Windows won't load.

My BDBG that I'm selling here like high voltage. That's why I thought they are PSC. But people told me they were BDBG ))

This is some pretty weak BBSE though, let me tell you...

[Shiranui Gen-An]

Speaking of BBSE, I'm pretty sure my Dominator 1600C9 Ver2.2 are not BBSE. The ICs are smaller and there are no white stripes on them. Must be some kind of BxBG.

Thanks for the pictures!
Can you post the entire IC code for my list? Thanks!

How it overclock? I think too that is pretty weak BBSE )
And I've never seen good BBSE sticks produced any company except G.Skill

[websmile]

I had some acceptable BBSE by OCZ, but that?s pretty much all I can remember at this IC apart from Gskill. GEIL BBSE are a legend - for su...... real bad

Nice to see that you have really strong BBSE and this isn't G.Skill )

Following up on this...My kit is Corsair, and Ver2.2. All the info we have thus far says they should be BBSE, right?


Look at the ICs...no white stripes!

single side sticks always can work with higher voltage, that kingston's chip is elpida BDBG

It seems that Samsung have introduced a new 4Gbit IC - revision Q.
Part numbers M378B5173QH0 / M378B1G73QH0 for 4Gb/8Gb OEM sticks.
Has anyone heard anything about them?

I ordered two 8GB (M378B1G73QH0) modules for platform evaluation purposes and received them today.
I think it is pretty safe to say that MFR will be superceded.

Tested on a AMD platform very briefly:

DDR-1866 - 8-9-8-24 / 1.575V
DDR-2133 - 9-10-9-24 / 1.575V
DDR-2400 - 10-12-10 / 1.575V
DDR-2400 - 11-12-12 / 1.425V

The tCL & tRCD behaves similar to Hynix CFR / MFR, however they scale very well with the voltage.
tRP is pretty much immune, with low voltages it is tRCD - 2 MEMCLKs however with higher voltages -3 MEMCLKs should be possible.
With some proper sorting and PCB the Q-die might become the fastest DDR3 IC yet.

Should I try them on Haswell?

[TaPaKaH]

Yes, please.
4Gbit B-die also runs tighter than MFR (on average) but it can't do much above 1250MHz. If Q-die doesn't have this problem, then it might indeed be the new top 4Gbit IC.

Haswell appears to be the most ed up platform I have ever seen.
Can't make the modules even post at 2133MHz, no matter what settings I try.
I've tried "Auto" settings, manual settings (including the voltages), different straps etc.

At 100MHz BCLK and strap none of my modules even post at 1866MHz.
With 125MHz strap I got a Hynix CFR to post at DDR-2500, but thats all.

All of the MFR and Samsung modules (B / Q) will just get the board to a reset-shutdown-reset loop.
The motherboard is ty too (Z87M-PLUS) but ASUS has validated it at DDR-2800 according to the documents.

My experience on Haswell is around 10 minutes long, but it just can't be that hard can it?

[websmile]

It can - this is most y and unreliable platform I ever worked with, I guess it will take more than 10 minutes even for you to tame the beast

Try setting secondaries at least per hand to settings you think are safe, 2t, change slots, there are lots of options left - good luck

If you want to overclock any RAM in 10 minutes you should try Z87 OC Formula. When I first time tried to overclock memory on Z86 I just selected desired memory profile and it was enough for good result.

How does one order said two modules, mate?
I'd like to get some of those. Many thanks.

[ZenEffect]

sounds like a compatibility issue, may want to take a peek at what is broken in their bios.

or

get you an asrock

Ordered mine from Flexxmemory.
They arrived in two days, which is pretty damn quick.

M378B5173QH0-CK0 (4GB Single Rank)

M378B1G73QH0-CK0 (8GB Dual Rank)

Tried older bios versions on the Z87M-PLUS, they made no difference.
I also tried adding a XMP profile taken from a compatible 2666MHz CL12 MFR dual rank kit.
It appears the bios is not even able to interprete the XMP profiles properly. It doesn't set the secondary timings at all eventhou they are specified in the XMP profile. Tried to set the main and secondary timings manually based on a MFR timing set, it made no difference either.

On a 5800K Trinity APU I was able to make them run at 1308MHz 12-13-13 with 1.52V.
Didn't try any tighter timings or higher voltages as the IMC isn't very stable even at that frequency.

I'm not going to waste any more time on Haswell or AMD.
Afterall I am gone anyway pretty soon.

say it isn't so! without you, who will point out the jackassery of oems? not many have the skillset that you possess to point these issues out.

Set TRDWR + TRDWR_dr+dd set from tertiary manually to relaxed values like 15-16 whatever,then u will be able to boot,then u tighthen them up.It's a ty issue and it was reported llong time ago by me....

I've already tried to loosen up all of the timings, it changes nothing.

The way it shuts down, it is almost like the board is hitting some sort of hardware protection (OVP/OCP).

The CPU should be fine as it is a brand new part, never molested.
Surely no IMC can be this bad, can it?
