A64Info - New CPU ID and memory tweaking tool! - feedback welcome...

Regarding voltage change, please read this post.

This is "legal" way of changing it as AMD documentation describes. I wouldn't suggest more than 1.55V for core, without serious cooling (watter or something better).

Is "VID Ctrl" something specific to a certain chipset or mobo bios? I don't see it on my AT8-32X. 1.55V for core is more than I feel comfortable with anyway even on my water.

This should be CPU dependant. Check this table.

This is what happens.
When I define 1.425 in bios for example and then adjust "new" voltage in A64Info 0.62 from my default 1.35 to 1.4 (max) ...I then get an overvoltage on my 1.425 approximately +.05v. I just thought it odd and possibly worth mentioning.

This is great! help me get and extra 50 mghz on my memory becuse the devider on my rs 482 only does 6/5 I set it to 180 devider and now my ram is running at much more appropriate speeds.

[chenxy]

at first, good for you, lukija.

i have one more thing to ask. i'm using an asus integrated am2 mobo (m2npv). it doesn't have any kind of serious tweaking setting in the bios. but your fabulous tool can adjust the vcore from 1.4 to as low as i want. i just want to know we made this 1.4v as a threshold, amd, asus or you sir?

BTW, there is another weird thing i like to share. sometimes, an am2 3000+ can run at 2.7ghz with 1.4v and my super cheap 667mhz memory reaches 1ghz with default timing sequence. i run everything i can imagine simultaneously, testing software, surfing the web, emule, playing games and even scientific calculation. it goes like a rock. BUT, it cannot even reach 2.4ghz at some day. this mobo kinda have some emotion, i guess

AMD. Please see table attached (this one goes for AM2 CPU).

Any Chance you could add mem voltage to the mix

[lukija]

No. I don't think it is possible.

[take2]

if i say you saved my life it wont be wrong.with my nonoverclockable nf4 mobo i reached 2,5 ghz with 3200+ venice. thanks a lot but it still reboots itself. i saw that another 3200+ does the same. when i want to oc, i start ver 0.62 then it reboots and after reboot i start 0.62 again and this time it works. but if i close program(it still works) and start it again it reboots computer again. this is the only problem for me. and if you can find a solution for htt multiplier i will be really happy (if there is a way to reduce it please tell me)

[bdleonard]

I have a small problem with the 0.62 beta version. I am no longer able to change the CAS latency of my memory. I'm stuck with the default value of 2.5, and cannot raise it to 3.0 or lower it to 2.0. When I change the value in the dropdown box and press "Set" the value just reverts to 2.5. This worked for me in v0.5 and the earlier v0.6x betas. Any suggestions?

[lukija]

Yes, that is correct. I forgot to mention, since changing CAS will likely freeze your system i've disabled it. If it is OK I can unlock it.

[nick2crete]

Congratulations also from me for the very good programm !

Lukija i want ask you if would be possible to add all the dividers in A64Info please..(plus 180:200&175:200&160:200& etc..)
Sometimes is necessary to have them all for stable o/c ..
What you think? could it be done?

[lukija]

@Nick@crete: You cannot make custom divider just like that. AMD has integrated memory controller and memory speed is obtained by dividing CPU speed with some integer value. That integer value is controlled via memclk frequency bits ( originally only 2 bits thus 4 dividers available - 200,166,133 and 100). But there is another undocumented bit so with 3 bits you can have 8 dividers: 200,183,166,150,143,133,120,100). Newer revisions have one more bit (or maybe 2?) but only couple of them are known (217,233,250).

Please try calculator and see what happens when your CPU is not overclocked, try to use various dividers (memory clock). Remeber, memory divider is integer value and memory clock is target memory speed (of nonoverclocked system!). By dividing CPU speed with memory divider you should have memory speed less or equal (never greater than!) target memory speed. When you overclock your sistem, divider remains unchanged but since CPU speed changes so does memory speed.

Example:

1) stock CPU , Opteron 175 , 2200MHz (11x200)

If you want to run your memory at 200MHz, so you chose 200 divider which gived 11 memory divider so 2200 / 11 = 200Mhz.

But you cannot run it at 175MHz! If you choose 180 (which is actualy 183.333) , memory divider is 12, so 2200 / 12 gives 183.33MHz, it is greater than 175MHz. Ok, so you chose 166 divider which gives 14 memory divider and memory runs at 157MHz (it is not even 166MHz).

For 175MHz you need 12.57 memory divider. You see that is not integer value.
Try to play with calculator and see what happens.

Thanks for the reply,
I thought it was kind easier as it is..
Anyway, keep the good work man ..we wait your final copy...

The CAS Latency setting worked well for me, and changing it for 2.5 to 3.0 was the only way for me to run my RAM at the speeds I wanted. If it causes freezes for some, perhaps some warning text would be a good idea.

I am wondering if anyone can help me with this, its been bugging me for few days. I upgraded to Vista Ultimate, all works fine. A64info 0.62 i can not get it to load my .set file at startup. It worked fine in XP. I can load the file when its running no problem works fine......But when i use "C:\Program Files\A64info.exe" 200.set it doesn't load.......any help or insight on this would be greatly appreciated.

You may try new version of A64Info (still not tested fully). I have updated it so it supports ODC,dividers greater than 200 (beware, it may freeze your rig). Also, one can set it even if BIOS lacks this option (ODC). So far it's tested on Venice. Any feedback is wellcome.

Version 0.5
http://avala.yubc.net/~lukija/A64Info.rar

Version 0.62 (beta)
http://avala.yubc.net/~lukija/A64Info-beta.exe

Some screenshots:

Case 1 - multi 9, memclk 200, ODC off -> divider 9
Case 2 - multi 9, memclk 200, ODC on -> divider 10
Case 3 - multi 9, memclk 180, ODC off -> divider 10

I don't think that your old settings will work with a new install or differant OS i went from XP to 2K and couldn't load my settings, my advise is to screen capture your settings and apply them to your new OS and save..

No thats not it, im not using my old settings, im using new ones using saved .set file from 0.62. The problem is when i click or try to run "C:\Program Files\A64Info.exe" 200.set it does not load....

[lukija]

Logan, please use full path for settings file, something like this:

C:\Program Files\A64Info\A64Info-beta.exe C:\Program Files\A64Info\default.set

[loggan26]

Logan, please use full path for settings file, something like this:

C:\Program Files\A64Info\A64Info-beta.exe C:\Program Files\A64Info\default.set

Hi lukija and thanks that has got it loaded made the shortcut read like this "C:\Program Files\A64Info\A64Info-beta.exe" C:\Program Files\A64Info\200.set Bingo,,,,,, ram on lappy is back too Memclk 200 thanks a million for that.

it doesn´t work on my A8N32SLi-DLx

lukija, Can you please fix the 'Clock Generator'? Is working on ClockGen 1.0.5.3 (the new one, not the old Nf4) but is not working ths systool one.

It doesn't work on this mother board:
North Bridge: nVIDIA SPP100 (C51D)
South Bridge: nVIDIA nForce4 SLI (CK8-04) Revision A4

If you need more info about this motherboard just pm me.

thx

Any chance of someone testing A64Info under Vista x64? I would like to know if my low-level driver works.
Those who complained about Windows 2003 should also retest the tool.

Sorry, NO. It does not work under my Vista RTM HP x64, probably because driver is not signed. It tells "Error loading driver". But the program works fine under Windows XP x64 and Windows Server 2003, both 32 and 64-bit.

[Raulnsh]

Addendum to the previous post:
It is really unsigned driver. It it possible to turn off check of driver signing under Vista x64. This option is available in boot menu, called by F8. After booting inder "Disable driver signature enforcement" A64Info loads and works .
