New Memory Tweaker for Intel Chipsets

[Spyrus]

Looking back to my post in this thread you can find the beta version i got that worked well with my PM945 laptop chipset.
I have 2x2GB dual on it, CPU-z can detect 4096MB dual but memset can only see 2048MB and do not report 2x

Hey Felix,
First let me say a big thanks for your nice apps (Memory/CPU Tweaker).

Regarding the X58 chipset, why is it limited to read only and there is no option to change the ram settings from Windows ?
Is it likely to be added in the future ?

Thanks and keep up the good work

Because the motherboard vendors made sure their bios' set the IMC pci address space locking register after they change the settings. It's a security feature mostly though, to protect from priviledge 0 originating attacks like source/target decoder allowed DID imitating which would by pass the QPI and IMC ruleset to prevent this from happening.

Intel would have simply said if you don't lock the register space then we won't patch a critical bug that exists only on boards that don't follow spec.

That explanation is way too technical for me, I'm not that knowledgeable about computers.
From what I understand, the limit is caused by technical issues regarding security implemented by the M/B manufacturers ?
The board is preventing from editing IMC settings outside of the bios ? is that correct ?

So probably we won't see this feature in the future for X58 ?

Thanks for the explanation mikeyakame.

Yep that about sums it up. The Lock register is Read Write Once, so once it's been set it can't be set again until next reset. We haven't come up with a work around yet, and don't even know if one exists that wouldn't be considered an exploit tactic heh. Maybe one day it'll be possible if board vendors take the initiative to learn and implement source and target address decoder rules, as I think once rules are set up correctly the address space could be safely left unlocked. I feel their locking is probably just inexperience in the new architecture design, and they are safe from exploits in the meantime even though we can't set memory timings outside of bios.

Felix,

Small request for when you have some free time.

Would you be able to write a small function to calculate correct Refresh Period tREF turnaround value with respect to detected DRAM frequency and SPD REF Interval data and have that value as default menu item selection?

All it has to do is REF[T] = ( SPD_tREF * 1000 )[ns] / ( CK )[ns] where CK[ns] = 1000 / DRAM_IO_FREQ

The correct Refresh Period changes with frequency as you know, so having different values which can be selected is unnecessary. All It needs to do is detect what the correct value should be, and apply if something like Autodetect tREF option is enabled.

Let me know what you think anyway. To me it sounds like quite a good option, and it isn't much to write in c/c++ to do it.

Very handy program, Thanks!

I'm confused. Now that Core i7 support has been added to MemSet... whats the difference between MemSet and CPU-Tweaker?

[FELIX]

-> mikeyakame: I'll try to add it (probably in spd table) in a next version.

->003: MemSet is a memory tweaker wich work on practically alls CPU/Chipset,
CPU-Tweaker is a most complete version for K10 and Core i7 only.


CPU-tweaker finale version (some change since the last beta7): CPU-Tweaker.zip

Awesome mate, SPD table sounds great to me

working nicely, just missing chipset value heh

[FELIX]

Weird, I already add this chipset ID.
Could you send me a register dump at memset@hotmail.fr

Thank.

[eva2000]

Felix the cpuz dump can be downloaded here

[stasio]

Nice eva2000,3 different brand of DDR3 and VDIMM 1.84

[eva2000]

overvolted ram a bit as it can do 844mhz 8-8-8-24 1T at 1.815v too http://www.xtremesystems.org/forums/...d.php?t=216025

[Demo]

How can I fully disable all the settings made by memset, as I tried to run my memories at performance level7 ( from 8 ) now my system crashes at 400Mhz 1:1 i need to either boot in 266 or safe mode..

[FELIX]

Run memset, click on "Del.Save" button; otherwize, delete memsave folder in C:/windows and the shortcut in the StartUp folder.

Two chipsets ID for X58, I added the second in this version: CPU-Tweaker

[eva2000]

FELIX to the rescue again - thanks working fine now

[Gomnadz]

Nice little program here!!!! I wish I found this sooner!

any way to add the nForce 780i?

[FELIX]

780i chipset is already supported by memset.

Guys I have odd problem using Memset 3.6/4.0 beta 4. I can't change anything the only button that works are About and Exit, here is how does it look like:



I'm using Abit IP35-PRO and WinXP x64.

ISO: Help, thanks.

I have the same board/Bios 17, and posted same problem (#1089) in December '08, never got a response. Fortunately I had an earlier version (3.4) so uninstalled 3.6, reinstalled 3.4, and it works perfectly.

Good luck

[FELIX]

MCHBAR is locked on IP35 board since bios 11.
You need to got a modded bios for using memset on this board.
I tested it personaly and it's work, but use it at your own risk.

[mikeyakame]

Not sure if you got my reply email Felix, but the Memset build with automatic tREF is working nicely it seems.

THanks again mate
