Memory Multi 4e

[LordIT]

I can`t get the memory multi 4e. There are always short beeps (errors) after restarting. What does the letter "e" mean?

Not sure if this is the same, but on the blackops we have 1:4-cpu333 and 1:4-cpu400 and I would like to know what the difference is.. both result in the same mem/cpu mhz.

[LordIT]

Yes, perhaps my E4400 is not big enough. It is true that I can`t get FSB 400. Does it work with an E8400, which gets 400 Mhz easily?

[Xello]

Those are FSB straps, basically the northbridge chip has internal latencies as well as its clock (fsb). On blackops when you see 1:4 cpu333 and 1:4 cpu400 those numbers relate to the internal latencies, so the lower the number the better. Just like memory has a clock and latencies (8-8-8-24 etc) the northbridge chip has these too :) This is a short explanation and i'm sure Intel provide an elaborate one explaining their own spec on what fsb strap should be used for what clock etc somewhere.

Pass on what "1.4 e" means though...

And you can adjust the straps separately on BlackOps cant you? Can you adjust for example strap 333 and FSB 400? Is that for better performance?



The 4e feature was added with BIOS G26:

Yep.

Might want to PM Saaya about this one, though, or just wait for a reply :up:

[HDCHOPPER]

ya and post back here about "e" been wondering about it myself

[LordIT]

Does your windows boot after adjusting 4e?

[HDCHOPPER]

havent used it yet
thats why eye wanny know hahahaaa

[saaya]

i fired off an email to our bios engineers, ill let you know as soon as i get a reply :toast:

1:4e is forcing the 266FSB strap according to our BIOS engineers :toast:

[HDCHOPPER]

exellent !

[LordIT]

1:4e is forcing the 266FSB strap according to our BIOS engineers :toast:
If I chose Memory Speed 1:4e the 266FSB strap would be fixed, right? So I could adjust CPU Clock to 300Mhz and the 266FSB strap is still in NB. It is a play on performance - would be nice but I can`t start my computer not even with CPU Clock 266Mhz:

http://www.abload.de/img/p1070342k7ry.jpg (http://www.abload.de/image.php?img=p1070342k7ry.jpg)

If I adjust Memory Speed 1:4 instead of 1:4e everything will be all right.
What can I do to start my Mars with Memory Speed 1:4e?

[HDCHOPPER]

did you change mem timings to 266 profile ?
and eye bet the nb would need more volts to force that high mem speed at 266 strap

[saaya]

its more about chipset timings actually... so try higher chipset voltage...
hmmmm tbh the 266 strap isnt that useful actually...
333 has the best speed/perf ratio, 266 is tight, but not very clocking friendly at all...
can you boot at 200fsb with 266strap?
or doesnt it work at all?

[LordIT]

I acted on your advice. There were short beeps again. Here are the settings:

Do you have other ideas?

[LordIT]

Which settings did the engineers have that they could release BIOS G26 within Memory Clock 4e?

[Xello]

Yeah don't bother with the 266 strap, i can't get any kind of a decent clock at all on the blackops when i try to go lower than 333.

[saaya]

hmmm weird... sounds like the strap doesnt work at all... at least for you....
what cpu are you using?

[LordIT]

Intel C2D E4400 (signature)

[saaya]

ok... ill check

[LordIT]

Which strap do I have with these settings?

[Bullet92]

Saaya , can you post list of straps? (for ex. 1.4e = 266 and so on...)

The strap is given by the "CPU clock vs memory speed" setting, where 1.4e will force 266 strap 1.4 standard should give you 333. The 266 beside "cpu clock" is your fsb, which is independent of your strap.

[Gendo]

I thought the strap was picked depending on the fsb you set? Meaning: setting 266 fsb will boot the 266 strap. Booting at 500 will enable the 400 strap.

there should be 4 straps in total: 200. 266. 333 and 400 if I'm not mistaking.

Assuming this works the same on Foxconn board as it does on any other board:p:

[LordIT]

I think the CPU FSB will be independent of the strap if the strap is fixed.

I agree with you. Yes, CPU Clock 266 should booting the 266 strap but 200 strap is possible, too.
The 1:4e strap seems to me quite mysterious. :confused:

[Xello]

I think the CPU FSB will be independent of the strap if the strap is fixed.

That's what i meant, yeah.

The strap is an independent value from the fsb, but if it's not fixed it will set itself depending on the fsb clock you choose. You don't really have to worry about that, though, as it takes care of itself.

So all the 1:4e setting does is force the strap (internal northbridge sub-timing representation) to 266, regardless of what you set the fsb clock to. I think it's better to call the strap a 'representation' because from what i read it's a number that relates to other timings that aren't all the same, just like memory has sub-timings.

Again, though, from my experience you should stick with the default (1:4) as it'll let you set clocks as high as possible.

[LordIT]

Perhaps the Foxconn engineers didn`t fix the strap 266 but 333 accidentally. That could explain the mistakes in booting. 1332 Mhz is too much for DDR-2 - definitely! :lol2: :ROTF: :rofl:

[Gendo]

1332 Mhz is too much for DDR-2 - definitely! :lol2: :ROTF: :rofl:

Is that so?:p: I've run 24/7 at 1333Mhz 5-5-5-15 @ 2.35v:p:

[LordIT]

I guess that`s DDR-3 isn`t it.

[Bullet92]

I guess that`s DDR-3 isn`t it.

Why? :rolleyes:
DDR2 at that speed is normal. He probably have GKX/GMH chips so nothing weird except a little bit voltage.

[Xello]

Yeah that's not impossible for DDR2, there are chips out there that can do over 1400mhz. I'm sure there's a 'club' for it on XS somewhere!

[Bullet92]

I'm sure there's a 'club' for it on XS somewhere!

Yes it is HERE (http://www.xtremesystems.org/forums/showthread.php?t=123294&highlight=700MHz+club).

[Gendo]

Yeah it's ddr2, gmh chips. They do 622 4-4-4-4 too:)

[LordIT]

I tried up to 1160 Mhz.
I think my D9GMH- chips are not too bad. How much could I try without taking a risk to crash it?

[Bullet92]

I had one kit of Ballistix (R.I.P) and keept them 1200 @ CL4 with 2.35V for 24/7 but Mars killed them after 3.3V and by that moment the board don't like any memory :(

What kind of voltage was that 3.3V?

[saaya]

heres an update for you guys, the bios engineer said that you might need a kit of memory with EPP profile to use the 1:4e divider.
this divider was added specially for EPP profiles apparently... weird... well id say just download an SPD from techpowerup that has an EPP profile and then check if it works?
be careful not to download and flash an SPD profile that might not work on your sticks tho :D

[LordIT]

EPP is for SLi only, isn`t it? :confused:
How can check if my memory supports EPP (I searched in CPUz and Everest)?

[HDCHOPPER]

hot dam that should work with my dominators :D

[Bullet92]

What kind of voltage was that 3.3V?

3.3V for memory/vRAM (3.365V = max) :D

Would it be enough to change the EPP indentfier? I could change command rate 1T, too! :eek:


I have that D9GMH chips (signature).
Can I choose any D9GMH SPD- files (1024 MB) to flash?
Which of them have EPP support?
http://awardfabrik.de/forum/showthread.php?t=1255

[HDCHOPPER]

wait a min ... epp & xmp profiles are close enough to the same thing as far as bios is conserned ?

[LordIT]

Does the Mars support EPP at all?

[saaya]

the newer cpuz versions all show if EPP is present on the memory sticks and they even show the profiles :)


Would it be enough to change the EPP indentfier?
no, you need an actual EPP profile in the SPD

wait a min ... epp & xmp profiles are close enough to the same thing as far as bios is conserned ?
no, they ware way different... not compatible...
pretty much the same infos but coded in a completely different way in the SPD


Does the Mars support EPP at all?
well i suppose so, why else would there be the 1:4e option which was added for EPP modules? :D

[LordIT]

be careful not to download and flash an SPD profile that might not work on your sticks tho :D

It is hard to get information concerning compatibility. I think I should chooce a SPD file from a 1 GB DG9MH chip with EPP - support. But I only could find a 1 GB D9GKX chip.

Can a Micron D9GKX- SPD file be flashed to the Micron D9GMH chip?

[LordIT]

Downloaded a SPD-file of Mushkin XP2-8500. It is from a 1 GB D9GMH Chip and has that EPP support. :D
http://www.virtual-hideout.net/reviews/Mushkin_XP2-8500/index.shtml

Perhaps I will try to flash tomorrow!

http://www.abload.de/img/unbenanntgex.jpg (http://www.abload.de/image.php?img=unbenanntgex.jpg)

[saaya]

gkx and gmh are the same chips, they are just different bins :)
micron chips can run very tight timings, so spds from other chips usually always work on micron since other chips use more relaxed timings.
micron spds instead might not work on other chips since they cant run as agressive timings.

[LordIT]

So I have to make a choice:

Shall I keep on the same company CellShock with D9GKX or try the Muskin D9GMH? Which one is more compatible? :shrug:

[Bullet92]

Saaya , can you post list of straps? (for ex. 1.4 = 333 and so on...)

Saaya? :rolleyes: :)

[Gendo]

Straps aren't set by your memory divider...It's set by the fsb you use. There are 4 straps: 200, 266, 333 and 400. So unless you pick a divider like 1:4 333 it will be set according to the fsb you use to boot. Try booting at 399 and look for max fsb, repeat with 401 boot and you'll see;)

About the spd's: it doesn't really matter what kind of chips the spd was designed for because you always have to try out if the spd settings work for your stick by manually applying what the spd says. If you then run memtest and it doesn't return any errors you could flash that spd onto your sticks. You don't want to just guess by looking at the chips.

Example: I have 2 sets of D9GMH: dominators and balistix. With 2.5v the balistix do 716 CL5, the dominators only 640 CL5. You see my point?;)

[LordIT]

Straps aren't set by your memory divider...It's set by the fsb you use.

But why can strap 266 be fixed by the divider 4e?

[LordIT]

Here is my old memory. CPUz version 1.40.5 is the last supporting EPP. The newer ones up to v.1.48 doesn`t:
http://www.abload.de/img/cellshockram5q5i.jpg (http://www.abload.de/image.php?img=cellshockram5q5i.jpg)

I flashed that Muskin SPD into my memory chip. Its so easy to get a new memory and so cheap. :D
http://www.abload.de/img/flashingavri.jpg (http://www.abload.de/image.php?img=flashingavri.jpg)

After CMOS clear I had that memory with default settings:
http://www.abload.de/img/mushkin25ixc.jpg (http://www.abload.de/image.php?img=mushkin25ixc.jpg)

Then I tried that mysterios divider. I only adjusted 1:4e - no other changes in voltage, chipset, etc. And the result:

Memory divider 1:4e works properly with an EPP supported memory!!!


:YIPPIE: :up: saaya, you are my hero!! Thanks for that. It is nice to have such an exellent support!!!:up: :YIPPIE:


Tomorrow I will start a 12 days holiday to the Domenican Republic. :surf:
After that I will test the 1:4e on performance. :banana3::banana3::banana3:

[HDCHOPPER]

hot dam Lord !! glad to hear that ... when ya get back do a thread or pm me on how step by step ya did that got some sticks here eye need to flash to get more mh out of them for my dice run !! :D thanks to SAAYA AND mxpc for the pots :D:D:D:D:D:D:D:D:D

my Firesticks will only do 1200 stable and to get high cpu clocks my memory the thing thats going to hold me back for shure:mad:

The divider 1:4e fixes strap266 So I thought that divider 1:4e is not so good at FSB 150. But there is no difference between 1:4 and 1:4e:
http://www.abload.de/img/1500multi4epaax.jpg (http://www.abload.de/image.php?img=1500multi4epaax.jpg)

I overclocked up to FSB 290. Here is the result of 1:4. It is hard to get 8300 MB/s in read. This is the best result of 10 tests:
http://www.abload.de/img/2900multi4c2d3.jpg (http://www.abload.de/image.php?img=2900multi4c2d3.jpg)

Divider 1:4e has a better performance. There are 50 MB/s more in read at least! Each of the 10 tests was more than 8350 MB/s: :banana:
http://www.abload.de/img/2900multi4em620.jpg (http://www.abload.de/image.php?img=2900multi4em620.jpg)

In additition I can start my memory @1200 MHZ @1:4e. If I start
@1:4 I will get short beeps after restart. So 1:4e is the better overclocking solution. :banana:
