New Memory Tweaker for Intel Chipsets

[JWilson]

->JWilson:see at the top of each register in datasheet,
the addresse(offset) is indicate.
But 965 configuration register is more compliquated
than others,because Intel use 8bits,16 bits,24bits
32bits and higher values......

OK, but that wasn't what I meant.....

How did you know:
??h = Tras 18T
??h = Trw 5T
??h = Trrd 4T
??h = Trp 3T
??h = Trfc 12T

Where did you find the hex bits that equal the different timings?

They are not listed on the datasheet:

[FELIX]

Exact,it's not indicate in the datasheet,
so I think that (on a 4 bit value,for example)
0h->0T
Fh->15T

For yours values,it give:

12h = Tras 18T
05h = Trw 5T
04h = Trrd 4T
03h = Trp 3T
0Ch = Trfc 12T

tCl is different:
00h->tCl 3T
07h->tCL 10T

It's what I apply with memset on 965 chipsets...
others chipsets are differents.

[JWilson]

OK, so we more or less have to guess at them, but it's pretty easy to guess what they are...

AMD datasheets have each one listed. No guessing

Thanks!

[ReelMonza]

Is there a way to implement memory dividers as well or is it impossible ?

[laziepig]

How nice if u add 2 more options for frequency and voltage on ram... This will be an ultimate mem tweaker

[JWilson]

@ FELIX: 1 more question:

Is "FED14XXX" that is shown, the "Configuration Address" for the Data being displayed? I know the "XXX" is the register offset. Thanks!

[FELIX]

Yes it's the memory configuration registers or MCHBAR
(Memory Controler Hub Base Address Register)
You can find the address in B:00 D:00 F:00
at offset 48h for 965 chipset and 44h for 975 chipset.

[FELIX]

Here is a beta version of memset:
MemSet31

-add support for 680i chipset.
-add reading frequency for all chipsets,(except for 680i),
but possible bug with this fonction,ratio fsb:dram is a very
gas-works on 9xx chipsets.
-Changing reading memory size
-add values fot tRAS on 975 chipset
-some bugs corrected.

Report me bugs or problem...

[Dumo]

Thank you Felix ...

[FELIX]

memory frequency don't work on 680i chipset,it's the fsb frequency...you are lucky (1:1)
I don't find how work memory ratios on this board.
I'll try again to get 680i datasheet (I need it for do that)

[webwilli]

thanks for update.

i get this error when i start memset:



Asus P5W64 Pro
Windows XP SP2

[FELIX]

?? What is your system?

Basically we can match FSB and memory in bios any which way...




or...

[DeToNaToR.cl]

I found this weird bug.. it happens always..using Memset 3.0


I open Memset, its ok it works just fine


Then I change the timmings (same thing happens if I just close it without changin anything)

If I open it again, it will show this.


and CPU-Z wont show anything in the mem tab.



PS: Gigabyte DQ6
PS: Same thing with 3.1 Beta.

[webwilli]

?? What is your system?

Asus P5W64 Pro i975
Intel Q6600
2 x 1024 MB G.Skill DDR2 F2-6400CL4D-2GBJS
MSI 8800 GTX
Windows XP SP2 all updates

more??

memset 3.0 works perfect.

[Blacklash]

I'd just like to say thanks for memset too. Having access to things like tRFC makes a difference in the speed and feel of my rig in general use. Great little app.

[FELIX]

->Detonator.cl:Read post #234 on this thread.
->webwilli:I send you an m.p.

[Phil The Greek]

Nice work FELIX.It works like a charm
What tRFC would you suggest?

[FELIX]

The best is make test yourself,but bachus tell me that tRFC on this chipset are
less influence than tRFC on others chipsets.

[bachus_anonym]

That's what it looks like from messing with TRFC and MemSet. Current BIOS (P21) for reference 680i boards (eVGA, BFG...) does not allow to adjust TRFC, as opposed to e.g. latest BIOS for ASUS P5N32-E SLI... So that's all we got for now...

SPi32M --> TRFC=70 vs TRFC=20 @ DDR2-1315 5-4-4-5.0-2T

Not much, but hey, 3s is 3s, right? Everest and Sandra memory benchmarks do not show any ground-breaking differences either...

Thanks for a revised version, FELIX... Hopefully you'll get memory clock and ratios figured out soon

thx a lot!

[G H Z]

Thanks FELIX, much appreiciated revision

Jesus Bachus, nice mem clocks an 1M!!

[FELIX]

Here is the final version:
MemSet31

Finally I don't find how to report memory frequency on 680i...
Let me know if you find bugs on this version.

[joe_cool]

Let me know if you find bugs on this version.

This message gives me memset on a bad axe 2.

[webwilli]

Hi FELIX,

thanks for new version.

The memory frequency are not correct.
