WPCREDIT tweaks for the A64

[TheMeatFrog]

Chop Chop gurus me and Shadow needs some answers! J/K much <3

[maedox]

Check out the screen shot I provided. RAM is in 2x512 dual channel running at 250MHz and I can't get the value in red set to 1 w/o lock up. Any ideas? Also any other changes to help improve performace would be greatly appreciated!

What voltages are you running your system at?

[TheMeatFrog]

What voltages are you running your system at?

cpu 1.6-1.63(1.450 +8.3%) and my ram is running at 2.7v.

[shadowing]

So are these usual tweaks?

Read Write Queue Bypass: X16
Controller Mode: 128 Bit
2T Timing: Disable
Bypass Max: Higher is better?
Max Async Latency: <is better?
Mem Clk 0-4 enabled/disabled (what are these?)

I'm trying to get a good idea what settings are set to what in a fail safe config. I'm trying to start with the most conservative settings imagineable to try to figure out if I can get this notebook's RAM to do 200Mhz.

Can someone set their mobo's BIOS to fail-safe or something similar and then load up A64Tweaker and share what the settings are?

I've just tried to download A64 tweaker again for my new install and I'm getting a 404.

[slayer899]

i've seen people with a new version it seems from screenshots, is there a place to d/l this?

[CodeRed]

Sorry guys Ive been out of the overclocking scene for the last month or so to pursue a new hobby ... snake breeding.

The offcial release of A64 Tweaker is V0.31, this is also the best one to use. I did produce V0.5Xt which added some HTT settings, but these dont work. THe latest (untested) release is 0.6 which adds a few minor features such as Drive Strength etc etc.

Anyway you can download them all here:
V0.31
V0.5
V0.6

My new hobby will go quiet around May/June, thats winter over here and its also when snakes are at their quietest. So maybe around that time I will get another A64 rig and start the overclocking again.

CodeRed....

I have a dream.....and that is that A64Tweaker can have the snazzy feature of setting a 4x multiplier on my notebook while it is applying its settings. I've found that the only way to guarantee no lock up when changing the RAM clock speed is to literallly unplug the thing from the AC power (or use a proggy to set it to minimal power use, but the ac plug is much less of a pain to do)......

edit:
I managed to figure out a crazy way around this lockup problem. By using a batch file and removing the AMD processor driver (using MS's OEM driver), I disable PowerNow. Instead, using the batch file, I have Clockgen set the FID to 4x, then apply A64Tweaker, then load up RMClock which simulates PowerNow (and does it better with voltage controls and many advanced settings).

A64Tweaker.exe 200a.a64  //this one just applies some latency settings. I needed something before Clockgen cuz Clockgen doesn't like being first and gives a driver error

CG-ICS950403.exe -file=800.txt  //to 4x FID

A64Tweaker.exe 200X.a64 //apply latency and RAM clock settings

start RMClock.exe //load up RMClock

@CodeRed...

First of all, thanks a lot for the great tool you made :thumbsup:

Now... Let's get on with it In your latest release - v0.60 - you added quite a few new options like Drive Strength, DQS Strobe Timmings.... By doing so you pretty much gave MSI K8N Neo2 users all the RAM tweaking options that they've never had available in BIOS but e.g. DFI NF3/NF4 enjoyed for some time now . But there's one more I'd like to see - Bank Interleave 2-way/4way

Is it possible to add that option at all ??? Can you comment on that, please...

Best regards,

EDIT: Damn.Silly me. I must have missed Tictac's post above about bank interleave... Hopefully, you will be able to add it in your next revision.

thanks for a64 tweaker :p

[enduracell]

Codered thanks for ur great tool once again
the load profile doesn't work correctly on version 0.5 and 0.6, are you planning on fixing it?
Also the LDT multi on version 0.5 was working fine, imo this is the option that should stay on future releases as it's the only tool that could change it on the fly...

[CodeRed]

A fix for V0.6 will have to wait until I get another A64 rig .. probably around May/June (thats winter down here) before I start overclocking again.

The LDT multi in 0.5 only appears to work. This version only changes the CPU registers not the chipset and doesnt perform a LDT reset so the changes dont actually take effect. Some of the buffering parameters do however seem to take effect. If I could get hold of the chipset data sheets than maybe this feature could be made to work properly.

V0.31 is still the latest fully tested release. The others were just experimental and couldnt be tested due to my lack of hardware.

As for mem interleave, its very unlikely that this feature will work from within windows. Changing the interlave will also change the physical memory map and thus screw up everything already loaded into RAM. It may be possible to put the machine into a hybernation mode, page everything to disk, change the interlave and then reload the mem image form disk, but unfortunately I dont have enough technical info on how this is done by windows.

I am interested in getting the shuttle sn25p (small size) or maybe making computer out
of a nforce4 mini-atx board. (I think that msi is making one now).
http://techreport.com/reviews/2005q...5p/index.x?pg=5

I want ecc memory support of the unregistered dimms. The Asus A8n-sli Deluxe (according to bios option and manual) and the DFI nforce4 boards support ecc (according to a review I read). It does not seem from the info I have been able to gather that the shuttle sn25p does support ecc in the bios.

From my reading of an AMD tech document on the socket 939 processor, ecc is a processor thing. So that processor does support ecc of its unregistered DIMMs.

So my question is , if the sn25p does not support ecc in the bios, if I run the A64 Tweaker utility, will it really be able to override the bios and add the ecc functionality to the sn25p? Can someone tell me technically why it should or should not be able to . What could get in the way of that on the motherboard level? Will ecc unregisted dimms work in the sn25p, during the times the A64 Tweaker is not running? In other words , will the motherboard be smart enough to not use the extra ecc chip on the dimm during initial boot up?

Can a64 Tweaker be incorporated into the boot up sequence? After the ec switch is set iin the Tweaker, can you shut down tweaker and the ecc will continue withought having to have Tweaker continue in the background?

Thanks,

Oh, and how can you tell for certain the ecc is really being used, and not just see a Tweaker switch? How does that really work? Can you tell if you run a memory benchmark without ecc, then run the same benchmark with ecc, and there should be a like 1/8th decrease is memory speed or something?

Oh, I take it, that once you shut down the Tweaker program utility, all the settings you made will continue until the computer shuts down?

Will A64 tweaker be able to start up from inside the new 64 bit windows that is being realeased?

If I wanted to run Linux or 64 bit Linux but needed the ecc switched on, could I boot into windows, switch it on though the Tweaker, then boot into Linux without hitting the reset switch. I don't know what I am talking about here. Would there be any sequence that would keep the toggles on the memory?

Thanks so much for help.

[sun_tzu617]

problem... I change values, and when i hit "Set", all the values go back to the original...

whats going on here?

[IvanAndreevich]

Finally tried it - 150 MB/s more in CacheMem32 No stability problems either.

[IvanAndreevich]

ROFL.. somebody try this. Drag a prime95 icon on the A64 tweaker icon. Instant reboot

[Crisao23]

Guys I just built a new box here.

It's a FX 55, 1GB corsair 1024 3200xl, powercolor x800xl and asus a8n-sli deluxe with bios 1006.

Will change to dfi when I have money.

Meanwhile I would like to tweak my memory in order to reach 6000 or a little more on reading tests. I don't want to raise voltage above 2.7/2,75 or raise the clock.

I wanna tweak to reach its best at stock settings.

Can you help me ?

Playing with A64 tweaker at the settings below I got the following results:

latency:

[J-Mag]

Is that TCCD stuff you are running? And it works at a cas of 1.5? (A64 tweaker crashes if I even try to change CAS ot a higher value for me and I am using the same board + TCCD, although I am using a winchester...)

Anyway, I think you should download the newer version .6beta cause there are more options...
OPB did a write up about DQS http://www.xtremesystems.org/forums/...ad.php?t=57925

Then also you might want to lower your refresh rate...

Also I have heard setting the read write queue bypass to 16x improves performance (if you read this thread you would know this as well, however they were uing BH-5...)

[Crisao23]

Yup, 1024-3200XL Revision 1.2

Works pretty fine at 1.5, including hours of gaming, sciencemark, winrar, prime95 and everest latest beta memory benchmark.

I'm starting to read more about it, thanks for the links. Lotsa info in one shot

[raydelee]

why everytime i press the set button on the amd64 tweaker my system reboot or hang?
i've follow the setting on the first post, is there any other steps that i need to do before changing the value using amd64 tweaker

thx

[andL64]

you cant set the CAS latency with amd64 tweaker try it in the bios and go with memtest

[raydelee]

you cant set the CAS latency with amd64 tweaker try it in the bios and go with memtest

even i dont set cas latency its still reboot
any step by step guide when using a64 tweaker

thanks a lot

[nordik]

Wish I knew what half these options did lol :p

[G H Z]

Code hope ya get a new A64 rig to play with soon
