New Memory Tweaker for Intel Chipsets

[The Nemesis]

@Felix
Here's a screenie of whats happening on G35. Cas is showing 10 Command rate 1T. Adjusting performance level seems to work but is had negative effect. Not sure what effect other adjustmests are having a system typically locks after hitting apply. Trying to drop done to 475 FSB now and try again.

Hello all!

I'm talking with some people over in the official abit overclock thread for this board, and a lot of us are not able to get MEMSET to work with this mobo. When you run the program, all the options are unchangeable, including the "lock mchbar" checkbox (which is checked), though im just guessing that this is the feature that locks/unlocks the mem timings for adjustment.

Anyway, someone mentioned that people over here had gotten it to work with an old BIOS of the board.

So, has anyone gotten MEMSET to work with the abit IP35-Pro (and if so, with what BIOS), or have any ideas why everything is "untweakable"?

Thanks!

->The Nemesis: I'll fix it soon.

->sirrealist: since bios 11, mchbar access is locked in write on Abit IP35, and I can't do nothing.

Damn... that BIOs is before they updated the microcode for the 45nm chips... no going back to that one.

What exactly us the "mchbar locked" option? Does it have to be unchecked to be able to change your timing values? I.E., since BIOS 11 we cannot change timing values using MEMSET on this mobo, or is "mchbar locked" unrelated to not being able to use the program to adjust timings on this board?

[FELIX]

Look at Bus 0 Dev 0 Fct 0 ,OffSet F4h, bit [0];
If bit[0]=1, your MCHBAR is locked in the bios, and is not possible to reset this bit under windows. Only Abit can fix this problem.

Visit the abit sector of rebels haven. The admin has mods for the ip35 pro board and if not the one you need, I'm sure he can make one. Just post a link to the bios you want modded as he is on dialup because of where he lives.

so, by unlocking the MCHBAR i would then be able to edit RAM timings using the program?

I don't really know what the MCHBAR is, and what the ramifications are of having it locked. Only when its unlocked can you edit ram timings using MEMSET?

About first question: yes

Someone locks MCHBAR to prevent using programs like MemSet. When it is unlocked, you can program it with MemSet or similar programs.

Called MCHBAR are the I/O memory locations of memory controller in PCI space: you can enable/disable functions or set timings.

-> sirrealist: Problem is mchbar can be unlocked only in the bios; perhaps with a bios modded.
Let me know if you can find it.

For Performance Level, I know that it's don't work on some chipsets, sorry.

Rebels Haven posted a mod bios for the IP35 Pro that adds new Items Performance Level and Trfc. It leaves my MCHBAR unlocked, but I'm running XP. Are you sure VISTA isn't locking it?

[FELIX]

...are you sure that you can apply settings with memset and this bios?
-I just flashed my IP35-pro with it (M629B_17.XXX) , run fine but mchbar still locked under XP.

[JWilson]

My mistake, I mis-understood. But Polygon just posted this:

Please re-download the Mod BIOS. Date on new files is 6/21/08. I added code to leave the MCHBAR unlocked so the Memset will be functional.....

[FELIX]

Thank jWilson.
I have flashed with Bios 17.
mchbar is unlocked and memset work fine now.

Here is the bios modded download main page: http://www.lejabeach.com/ABIT/IP35Pro/
a great thank at Polygon for his work.

Hi all,

I have an ABiT IP35 Pro board, and have flashed to the Modded -17 BIOS, am using Memset 3.5.3 beta, but Memset still shows "MCHBAR Locked" at the bottom and nothing is changeable.

How is Felix getting it to work or why wont it on mine? lol

Thanks, cool program if I could get it to function fully.

I have an ABiT IP35 Pro board, and have flashed to the Modded -17 BIOS, am using Memset 3.5.3 beta, but Memset still shows "MCHBAR Locked" at the bottom and nothing is changeable.

Have you reinstalled MEMSET? Maybe it's worth a try!

Oh, just saw it's your first post: Welcome at XS!

[Blitzman]

Thx for the welcome Don Dan,

Yep I just tried uninstalling Memset, turned computer all the way off, started back up and reinstalled Memset 3.5.3 beta but still getting MCHBAR Locked....

dunno why...

System BIOS : 05/26/2008-P35-W627DHG-6A79OA1BC-17

Thanks

oh yeah and i did let system reboot after re-installation of Memset

[JWilson]

Just make sure both "Invoke Boot Agent" Items are "Enabled". They are under "Integrated Peripherals".. The assembly code is substituted for the boot agent and they must remain enabled for the code to execute..

[Blitzman]

Well Geeya Mr Wilson, you sure fixed that one! LOL Was like thinking of Dennis the Menace talking to Mr Wilson har.

Yep that cured it! I had one Ethernet controller disabled cuz I was not using it.

Thanks very much!
Now I can more easily experiment

This should be a sticky note somewhere or something

Wow, I've seen some appalling unreadable forum designs, but that one takes the biscuit. Tiny text, white on black, link underlines obscuring the text... whoever designed that should be shot.

Sorry for OT.

Everything looks good except command rate still reads wrong. I'm showing 1T. Thanks for all your effort now off to bench

***Edit***
Cas lat still can't be changed

Hi Felix,
Not sure if your aware of this, apologies if you are.
Praz & I have found a few misreadings after manually changing bios values, with the
DFI UT X48-T3RS LanParty

Following on from Praz's discovery

tRD - 8.5, Memset Misreads The Value When Set Manually

I've found 2 more. These also occur when values are set manually in bios.
Working at 485 400/1600 on Auto
Write to Precharge Delayed (tWR) = 20
Write to read Delayed (tWTR) = 16
I manually changed to:-
Write to Precharge Delayed (tWR) = 22
Write to read Delayed (tWTR) = 17
with the resulting memset values :-
Write to Precharge Delayed (tWR) = 26 (+4)
Write to read Delayed (tWTR) = 21 (+4)

Memset Version 3.5

@memset generally. for me its a blessing from teh sky helps me a lot big up for the author keep it coming

Amen to that

memset is awesome

it helps me to go below the 4-3-3-3 Bios set mark to 4-2-2-1 1m stable at 1142mhz ddr2
