Sry to put all these questions on ya but i have a MSI K8T Neo board w/out the AGP/PCI lock and i dont have the money to buy another board with the lock in it. Is there any way what so ever that i can lock the agp/pci so i dont have to pay for a new board. Thank You

Thanks, CodeRed. NOt only did you develop the prog, you're also the problem solver. Very cool.

Now to figure out what I'm doing wrong. But first, I've got to get my clocks working in Clockgen-they've grayed out, and they weren't at first.

I haven't figured it out yet. Why I could at one time use the clocks and now I can't is beyond me. I'm sure I changed something in the bios that has bprevented me from doing so. I had changed the bios FSB back to 800 for stability, no clocks; so I knocked it back to 200 in bios, and still no clocks. Hmmm...

Are you having the same prob? If you figure it out, shoot me a message. We need to hope Asus gets off their A$$es and make a decent OCing bios, or at least a beta release. There is one beta version out in cyberspace somewhere, but it was in Dutch or something, and I didn't want my bios worded in Dutch.

Got it! To ungray the clock mode on Clockgen for the K8VSE, choose "auto" for performance mode (not standard or turbo).

In response to ur "no" Ive been thinking and brought the idea up with CodeRed that I noticed through the NF3 150's chipset release manufactures have been enabling the lock on some boards...simply by upgrading the "old" bioses and adjusting the FSB +1mhz in the bios engages the lock and other ways, I am since then wondering( I have a Shuttle XPC SN84G4V2 and it does not feature the lock, but has the 150 chipset)
I am actually beginning to believe it may be possible to lock the PCI simply by finding a register in one of the PCI Devices or somewhere with WPCREDIT.
It would be a heck of a find if this turned out to be the case. I just wish I knew where to start. CodeRed pointed out that the register may be different for every manufacture...makes it harder and would be nice if it wasnt =/
I think a way or place to start would be with people who have boards that have originally not had the lock engaged, then adjusted something or upgraded bios and had the lock engage, compare those 2 PCI dumps in WPCREDIT and see if there is any noticeblue helpfull difference.

hi folks!

thx to the great brain who uncovered this :D

amd64 tweaker is great!!!


i got the epox kda3+ and i only get 2,76-2,78 Vdimm...
and tested some with the tweaker since i got

Corsair 512MB DDR3200 CL2 /CMX512-3200C2 / XMS3202v1.1

this is bh-6 correct me if i m worng plz!

so this mem. only boots on 333 mhz :( but its not so bad its only worse because i can only set my multi to 8x (clockgen locks) in bios and i can only get 2250mhz so max what i can do is 225 like this i ve run the memory @ 2-2(3)-2-5 and it was quite stable in benches and win 24/7 but in games like d3 it cuts the game or i get bluescreens...

every time i set any other MEMCLK freq. it freezes i dont do any other refresh rate (tref) and only tested "ordinary" latency and Trc Trcf (10 12 ordinary and i tried 10/16 12/16)

i ll test some more but i cant set "bad" timings then the mem/board wont boot... (cause of mem. error...)

need more vdimm so i ll get 4 the dfi board!

on 200 i can run 2-2-2-5 with that vdimm and 245-248x9 @ 333

I've made some additional testing on a K8V.
Indeed, as long as the Performance Mode is set to "Turbo" or "standard" in the BIOS, there is no way to access the PLL anymore. Only the "Auto" setting allows the access.
I've some difficulties to find a workaround, so for the moment the only way to make clockgen work is to choose "Auto".

I have this same rig, I dont know if it locks but I can set bios to 201 & use clockgen. It will run stable up to 315 HTT, I always thought that maybe it was locking. I have know way of verifing this but it is know prob to run my OCZ PC4400 at 1:1 ratio on a 270 HTT bus.

So I've run into a problem that's hopefully easy to resolve. I installed the .031 version and installed by just extracting it to the desktop and executing. The first time I ran it, I was able to view my config perfectly. I wanted to reboot for a 3dm01 run, and after I did, I re-launched the tweaker and got all of those reserved fields, bad values, etc. Haven't seen anything different since. I have not had a previous version installed so I'm just wondering what my conflict might be. Maybe CPU-Z (1.23)? If this helps, this is on an Epox 8kda3j, 3700+, and a Win2k Pro install. It looks like a damn powerful utility, I'm hoping someone can help me resolve this.

Try deleteing the following registry key, and reboot:
HKLM\SYSTEM\CurrentControlSet\Services\cpuz

Then run the tweaker from your install directory. Make sure you have admin priveleages and write permissions to the install dir.

Just wanted to follow up. The next time I booted up, the tweaker read the registers fine again, just like the first time I ran it. I didn't have to edit the registry at all. Doesn't make sense to me since it wasn't reading correctly with several previous reboots, but I'm happy now.

damn urs runs stable that high?!?!?!
I notice in clockgen my PCI bus raises when I OC does urs?
I think it actually is because my Western Digital 160JB will start corrupting around 38mhz PCI bus...and its been that far and has corrupted =(
AND ur using SATA too which supposedly hates PCI overclocks more then PATA....

Not from within Windoze.

If you change the intyerleave then you change the order of physical memory addresses which would totally screw the current memory map.

Is there any way to at least detect if interleaving is enabled? CPU-Z's bank interleave is greyed out :(

Any way to mod the interleave via modded BIOS?

There is an Interleave driver for old VIA chipsets (PIII, K6) which enables memory interleave. So I guess there IS a way. It requires a restart, though.

Can you post a screenie using WPCREDIT of bus 0, device 24, function 2. From these settings I can tell you what type of interleaving, if any, is being used.

I may add an interleave info page in the next version of A64 Tweaker ... or just send the info the Franck so he can incorporate it into CPU-Z.

If it can be done via Driver, I think WPCREDIT should be able to do the same thing without causing windows to crash? :confused:

On the A64 you have to shutdown the DRAM controller whilst programming the DRAM CS & Mask registers. These control interleaving. Also once the interleaving is enabled the pyhsical memory map gets changed, so windows would be totally screwed.

There may be a way to do it from a DOS program (all running from cache), then jump into a bootstrap routine which bypasses the BIOS mem setup and loads windows, but its a lot easier to do it from the BIOS.

Checking for interleave is a bit messy, the DRAM CS and Mask registers tell the story. Get 26094.pdf from the AMD web site and read pages 71-79. It explains how these registers work. The easiest way to determine if the banks are interleaved is to check if the Base addresses for each consequetive bank are offset by 8 bytes.

If I could make a program to select the interleave I would. But unfortunately I belive it can be done from within windows.

Eventually, I will add a mem interleave display to A64 Tweaker. At least this will show you your mem configuration.

A64 Tweaker is used to get the most out of your A64 by allowing you full control over all the useful memory settings. Originally I wrote this because my AN50R BIOS was so lacking in memory timing options. Only the latest DFI BIOS allows such fine control over your timing options (amazing how similar the new DFI BIOS options are to those inA64 Tweaker :D ).

The ultimate goal is to have the tightest memory timings at the highest possible freq ... a good target is 2-7-12-2-2-5-2-2-1-1 (really need BH5 for this), but dont worry if you cant hit such aggressive values. Start at something like 2-10-13-2-2-6-3-3-2-2 and work your way down testing at each step.

I used SuperPi and Pifast to test the effectiveness of each change to my timings. Its best to choose a proram that really stresses memory and gives good systematic results (3DMark is a pain to tune since it varies from run to run).

I cant tell everyone what their best timings will be since it varies from RAM module to module. Some sticks work with agressive vaues others do not and you are better off with relaxed timings and higher FSB. You have to test your own sticks and see what works best for you.

Attached is a screen shot showing the values I get the best 3DMark, SuperPi and PiFast times with. My Kingston BH5 sticks run up to 274-277 MHz with these settings @ 3.6V.

PS Dont worry about the extra Link settings in V0.5XT for now ... I am still working on it ;)


w00t shaved a second off superPI im at 37s now at 235x10 with your timings in the screenshot except max async latency is at 5ns instead of 6ns, is this good? comp locks if I set that to 4ns. also that 13 is set to a 12, locks if set to 11. My goal is to get superPI to less than 30 seconds at 238x11=2.62GHz, some dude gets 31s with his stock 3000+ so I got a long way to go still. bartons dont do as well, my friend has 38s at 2.6GHz on his barton, is this a bad or good number

Max async latency of 5ns is very good.

If you want a 30 sec superpi score, you'll need approx 2766 MHz (11x251) from a S754 1Mb chip. Thats a tough ask on air.

If you want a 30 sec superpi score, you'll need approx 2766 MHz (11x251) from a S754 1Mb chip. Thats a tough ask on air.

Max async has quite some impact on performance, but there are two cases it has to relax:

1. Running more than 1 stick
2. Running at async

In my case my Hynix DT D43 can set max async to 7ns at 265MHz 2.5-3-3 for best performance. However once running 2 sticks, 8ns is a must for stability, and Vdimm won't help at all.

And at any non 1:1 ratio, 7ns is no go.

With only 1 stick, setting to 8ns won't let me go any higher.
Setting Max async to Auto in Lanparty BIOS is equal to 7ns in my case, for both 1 or 2 sticks.

Refresh rate (Tref) will have a healthy boost when set to 166 MHz 1.95us, but it might not apply to all memory.

As codered said you probally need around that speed on a 1mb.. But it has to be on 1:1 - Otherwise there´s no chance..
so: 238x11=2.62GHz would not get you anyway near 30sec.. more likely 34 or 33 :)

And you friends barton is a bit slow -- I guess he´s using a fsb around 230 to get that result :)

"Refresh rate (Tref) will have a healthy boost when set to 166 MHz 1.95us, but it might not apply to all memory."


it says reserved value to me, does this mean unavailable or something? I also have the option to set ras-cas delay to 1, but im too chicken to try, should I? its also a reserve value and if it doesnt freeze will this help any?

On my (now dead) AN50R / 3400+ running async didnt affect my mem timings. I could run max async = 5ns up to 250 MHz and 6ns up to 276 Mhz. Although I did get the same problems with two sticks @ 6ns. For stability with two sticks I needed to use 7ns.

I have never observed any significant performance boost by changing Tref.

Gents,

I've just found a way to really boost your A64 performance using WPCREDIT.

The A64 mem controller registers can be accessed using WPCREDIT using Bus #0, Device #24, Function #2. There are 4 main registers that I have been playing with:

0x88 DRAM Timing Low
0x8C DRAM Timing High
0x90 DRAM Configuration Low
0x94 DRAM Configuration High

The timings registers set all the DRAM timings params (as you'd expect), but there are many more than most BIOSes will show you. The best performance is obtained using:

Column Address Strobe # (CAS) = 2.0
Row Cycle Time (Trc) = 8
Row Refresh Cycle Time (Trfc) = 12
RAS# to CAS# delay (Trcd) = 2
Row to Row delay (Trrd) = 2
Min RAS Active Time (Tras) = 5
Row Precharge Time (Trp) = 2
Write Recovery Time (Twr) = 2
Write to Read Delay (Twtr) = 1
Read to Write Delay (Trtw) = 1

I normally write this as 2-8-12-2-2-5-2-2-1-1 for convenience ... not that rememering all those values is easy.

To set the mem timings to the above values change the registers as follows:
reg 0x88 to 0x02522311
reg 0x8C to 0x00000B00
(use 32 bit mode in WPCREDIT)

I have only begun to experiment with the Config registers but some of the things I have tried are setting the Asynchronous Latency Value (controlled by reg 0x94). Normally my BIOS sets this to 7ns, but when I dropped it to 4ns there was a healthy boost to my memory performance. To do this set bits 0-3 of reg 0x94 to 0100 (binary) (4 for those who cant read binary).

Just to make things more interesting, bits 22-20 of reg 0x94 control the DRAM speed (200, 166, 133, 100 Mhz). There are several reserved values, and I decided to try 110. Surprisingly this gave me a mem speed somewhere inbetween 200 and 166 MHz. This may be a 183 Mhz mem option I need to test some more to confirm these results.

Oh, 2T is also easy to disable :D

We no longer have to worry about BIOS updates, its all there in the DRAM registers. Over time I may write a simple windows app to set all this up in a user friendly fashion ... just need to find the time.

Only thing I cant do is set the bank interleave. Doing so would reorder the physical memory locations ... not something I think windoze would be happy with :p:

Try it and compare your before and after benchies with something like pifast or superpi and you'll see the boost.

codered i was using the ati driver:6.14.10.6490,things were going way good
due to zip drive problem i reformated,now the drivers are not on the sites the 6490?
i didnt save it anywhere is there any magic you can due.... :)

Just ask around or search the standard mirrors. I am sure someone around here has a copy ... I could do with a copy too ;)

Can someone take a look at section 3.3.13 of the BIOS and Kernel Developer's Guide? This register has some Read-Only bits which specify the valid settings (there are 16 available) for LDT Link Frequency. Are any of the "reserved" settings available? If so, what LDT multipliers do they correspond to? Are there any "hidden" settings in addition to 1x, 2x, 3x, 4x, and 5x? Even if additional settings are available, it may be the case that chipset support is needed in order to get it to work. Both sides need to communicate at the same rate.

EDIT: I found the following in the HyperTransport 2.0 specification doc.

Table 54. Link Frequency Bit Field Encoding
Link Frequency Encoding Transmitter Clock Frequency (MHz)
0000 200 (default)
0001 300
0010 400
0011 500
0100 600
0101 800
0110 1000
0111 1200
1000 1400
1001 1600*
1010 to 1110 Reserved
1111 Vendor-Specific
Note: Electrical requirements of the link above 1400MHz have not been fully specified at this time.

I guess there are no in-between multipliers other than 1.5x and 2.5x. The "Vendor-Specific" setting is 100 MHz (from the BIOS and Kernel Developer's Guide).

there is version 0.5XT of A64 tweaker which allows you to view all the link parameters, but uinfortunately setting them has no effect unless the link or CPU is reset. Since the LDT speed doesnt seem to affect benchmarks a great deal I didnt persue this line of tweaking.

Try deleteing the following registry key, and reboot:
HKLM\SYSTEM\CurrentControlSet\Services\cpuz

Then run the tweaker from your install directory. Make sure you have admin priveleages and write permissions to the install dir.


Awsome.. that fixed it for me too.. :)

Great program thanks alot..

Is it possible to enable 2T Timing when it's at 1T by default? I'm trying to get my RAM up to 200Mhz from 166.

While I'm posting I might as well ask what settings are most likely to get the RAM stable. For sure Tcl, Trcd, Tras. What else is essential? Or maybe, what settings would the worst PC3200 in existence use? :)

12-02-2004, 01:09 PM
you mean command rate of 2T? yeah see on the right hand side where it says "2T timing" put it to enable.

now I heard somewhere that older C0 chips are not capable of 2T timing...or are 1T by default but dont like being changed to 2T or something like that.

12-02-2004, 01:10 PM
2T Timing switches back to disable when I hit apply.

What settings would be conservative for the right panel? I don't know what to make of most of those.... the left panel just requires a higher number :)

CodeRed don't strain the brain! There is no any way to change the link frequency without support of a huge number Southbridges. I know how to change the link frequency by asserting LDTSTOP_L, but it works only with AMD-8111 I/O hub.

MEMCLK frequency should be set to 200 if you want 1:1 operation.
Dont worry about the Refresh Rate, leave the BIOS setting until you've figured out the rest.

Tref is the DRAM refresh rate. Refresh doesnt happen that often so it doesnt affect performance to badly. The less frequency refresh rates are best for performance, but it wont make any noticeable difference

i have a k8ns-ultra 939 and alot of the options are already available in bios... with the Tref - there are all sorts of values - and I dn't know too much about how to interpret it..

if i press Enter on it, the item at the top (which usually is lowest value) says 1x1592 or some numberlike that, while 2nd from the buttom it's 4x4672, and then at the VERY bottom, it's 128...

i'm wondering which one to use will give me best performance, and will changing this affect overclockability AT ALL?

Edit: I have already figured out the rest. Oh, 1 other thing, my Trc is set to 8 at the moment because you guys say it's the best performance? Well I can set this to 7 actualy, and it seems fine to me... hmmm

I didnt find that the refresh rate affects the OC much at all, but it may depend on the memory type.

The lowest refresh rate is best for performance, 15.6usec @ 200 MHz in A64 Tweaker. Not sure how the GB BIOS values relate exactly to the A64 tweaker values (from the AMD data sheets).

Firstly make sure its the mem thats holding you back, then try a touch more voltage

if that dont work then try upping each setting indiviually until something lets you go a bit higher
eg
2-8-2-2-5-2-2-2-2 as the next step up

Mobo is a workstation/server one (Iwill DK8N) so it doesn't support memory divider settings, its main reason I'm using a64 tweaker. I have also tried lowering my HT and trying it but it still freezes when I try and set it to 133. Funnily enough it WILL go to 100 and not freeze, but it is not reported in CPU-Z and clockgen.(Overclocking still seems too stress memory at 100 setting)

Hi!
I tried the A64Tweaker yesterday. First time it worked perfectly, but I set one value a bit too low and my machine rebooted. After reboot I fired up the tweaker again, and now it just shows (as it seems to me) random numbers.
Lots of reserved values and way too high numbers. I've tried re-extracting the tweaker, and on different hard-drives, but it won't work. Changig a value to something I know is right and hitting set resets the value to sh*t. :rolleyes:
What's wrong?

My hardware is:
MSI K8N Neo2 nForce3 Ultra s939
AMD Athlon64 3000+ winchester
OCZ PC3200EL Dual rev.2

tictac,

would you be so kind and tell something more about this? i would like to build my custom isa option rom and include it into the bios image, but i have a few questions. Which utility to program in do you use to build these option roms? I need to change the Bypass Max, located at offset 0x93h, bit 1-3 to 111 (or 7x) and the max async latency located at offset 0x94h bit 0-3 set to 1000 (8ns). I need that to include into BIOS cause else i can't run 7-3-3-2.5 timings on TCCD. If I use A64tweaker and set that at startup together with reconfiguration of timings from 8-4-4-3 to 7-3-3-2.5, it freezes. It doesn't freeze if i first set those two parameters and then edit the timings, but i must do that every time windows boots up, so I guess it would be a solution, to set those two in the isa option rom (i could set agressive timings in BIOS then too i think).

please answer tictac, i was searching the net for how to program isa option rom but i didn't find anything.

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 (http://home.exetel.com.au/codered/A64Tweaker/A64Tweaker_V031.zip)
V0.5 (http://home.exetel.com.au/codered/A64Tweaker/A64Tweaker0.5XTbeta.zip)
V0.6 (http://home.exetel.com.au/codered/A64Tweaker/A64Tweaker_V0.6beta.zip)

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... :brick: Hopefully, you will be able to add it in your next revision.

Codered thanks for ur great tool once again :toast:
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...

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.

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:

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/showthread.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...)

Hi all

Great tweaker code red! Its been a life saver for me as I cant set 1T ram timing in the bios on my K8N neo 2 :)

Was just trying your 0.5 beta and the Link Frequancy ( HTT Multi) seems to work fine on my neo 2 both cbid and sisoft sandra detect the front side bus changes.

In your last post you mentioned htt options not working so is it changing or not is what im wondering?

;This is my first operating system prototype :). One thing still
;obscured, the BEV mechanism mentioned in Plug & Play BIOS spec 1.0A
;don't explain about how the code executed :(. But based on my
;experiment it seems to be executed from ROM. So everything we do
;prior to loading the OS code from the expansion ROM into the RAM
;can't do anything dealing with memory write operation. I think
;BEV works as follows :
;1. During POST, the main bios recognize the LAN card as boot device.
;2. If we set up the main bios to boot from LAN as default, after POST succeded,
; int 19h (bootstrap) will point into the PnP option rom BEV of the LAN
; and passes execution into the code there, so we're executing code
; in the ROM pointed to by the BEV. Unless we're loading part of this
; code into RAM and execute from there, there's no writeable area in our code
;
;While the PCI function of the LAN card function as ordinary PCI card does
;so, the PCI init function has no direct connection with the BEV related stuff.

Hi tictac.

1.)
How to build a BIOS module which is able to run this code:

http://www.farb-rausch.com/
-->
http://www.farb-rausch.com/fr026.zip


; fr-026: 34b mul+cycle (uc 6.22 size optimizing compo entry)
; 1st place
; code: ryg (original concept) & kb (additional opcode crunching)
;
; rules were to write a "colorcycling" (no real colorcycling was
; required, only colorcycling-like animation) effect that display
; a x * y-ish pattern somewhere on the screen. the palette was
; required to look like the original version.

org 256

mov al, 13h ; ...load al with 13h (mode number)
int 10h ; set mode 13h

mov bp, 320 ; screen is 320 pixels wide

x les ax, [bx] ; es = end of mem (9fffh), ax = 20cdh
cwd ; => dx = 0 (for idiv)
mov ax, di ; get dest address
idiv bp ; div by width => ax=y coord, dx=x coord
imul dx ; mul x by y
stosb ; store color in vram
mov dx, 3c9h ; dac data
bt cx, 6 ; bit 6 of cx => carry flag
salc ; set al from carry flag
xor ax, cx ; => all this is functionally equivalent to something like
; "test al, 64" / "jz skip" / "not al" / "skip: blah"
; which should be somewhat easier understandable, but bigger.
out dx, al ; write grayscale pixel values
out dx, al
out dx, al
loop x ; pixel loop.
loop x ; skip cx = 0 to get the cycling effect!

; that's all there is to it.
; this is the 7th (or 8th) version; the first try was
; 49 bytes, from then on we successively made it smaller.


Well, I tried this...:
ASM:

push bp
stosb ; Store al to es:[di]
mov al,13h
int 10h ; Video display ah=functn 00h
; set display mode in al
mov bp,140h
loc_x:
les ax,dword ptr [bx] ; Load seg:offset ptr
cwd ; Word to double word
mov ax,di ; Fixup - byte match
;* db 89h,0F8h ; Fixup - byte match
idiv bp ; ax,dx rem=dx:ax/reg
imul dx ; dx:ax = reg * ax
stosb ; Store al to es:[di]
mov dx,3C9h
bt cx, 6 ; bit 6 of cx => carry flag
salc ; set al from carry flag
xor ax, cx ; => all this is functionally equivalent to something like
; "test al, 64" / "jz skip" / "not al" / "skip: blah"
; which should be somewhat easier understandable, but bigger.
out dx, al ; write grayscale pixel values
out dx, al
out dx, al
loop loc_x ; pixel loop.
loop loc_x ; skip cx = 0 to get the cycling effect!

HEX:
55AAB013CD10BD4001C4079989F8F7FDF7EAAABAC9030FBAE1 06D631C8EEEEEEE2E7E2E5

...and I used Bochs' feature to load Option/ISA ROMs.
But while booting Bochs with the compiled Option/ISA ROM,
there will be no switch to videomode 13h.
Bochs is still in text mode, but I can see sliding the colors of the background and the cursor.

2.)
Furthermore, how to insert a feature to break the animation
with any key
or
after a certain time?


3.)
How is it possible that "new" or nearly each todays BIOS's are able to display logos
in SVGA modes (640*480*256; 800*600*256; 1024*768*256; ...).
Do they already use VESA / VBE ?

But i guess the Detection is wrong, i've send the files to AntiVir. Addionally i found out when packing A64Tweaker with UPX and strip the Overlaycontent (Contains Debug-Infos, Paths and stuff), AntiVir doesnt alarm anymore.
If you want to continue using A64Tweaker with AntiVir, use this version -> http://rawhi.de/download/A64Tweaker_V0.6beta_UPX_OVERLAYSTRIP.exe

I'd like to experiment with these options a little cause my board doesnt have them in BIOS and they'll probably won't add them in newer releases, so I'd like to patch them through bios level as per tic tac's A64 Bios Tweaker... (http://www.xtremesystems.org/forums/showpost.php?p=917052&postcount=384)

Any input will be greatly appreciated.

Hi, can anyone assist me in finding which offset and bits to modify for the following options ?

Disable 32 Byte Granularity (A64Tweaker says its enabled, freezes when disabled)

Enable DRAM Bank Interleave (how do I check whether it's enabled or not ?)

*
*
*



32 Byte Granularity :

BUS - 0
DEVICE - 24
FUNCTION - 2
OFFSET - 90 (hex)
bit 19 ( 0 - disabled , 1 - enabled)

It works in combination with bit 16 (64 or 128 bit interface to DRAM), taken from AMD documentation:



Bit 19 Bit 16
0 0 8-beat bursts (64 bytes)
------------------------------------
0 1 4-beat bursts (64 bytes)
------------------------------------
1 0 4-beat bursts (32 bytes)
------------------------------------
1 1 4-beat bursts (64 bytes)
2-beat bursts (32 bytes) for Revision E and
later revisions if Burst2Opt = 1,
UnBuffDimm = 1, and En2T = 0
------------------------------------


Bit 16:

128-Bit/64-Bit (128/64)—Bit 16. Indicates a 128-bit interface to DRAM.
0 = 64-bit interface to DRAM
1 = 128-bit interface to DRAM



Regarding DRAM Bank Interleave, it is not that easy, I will try to find out more.

I've played with DRAM interleave option in BIOS (DFI LP UT NF4 Ultra-D, 623-3 BIOS) and here is what I got. Just to mention, I have 2 sticks of PQI Turbo (2 x 512MB) in orange slots.

BUS 0, DEVICE 24, FUNCTION 2

32bit mode

Offset 4C

Eanbled
00001001 (hex)
Disabled
02000001 (hex)

Differences (enabled -> disabled):

Bit 12 (1 -> 0)
Bit 25 (0 -> 1)

Offset 68

Enabled
03E0EE00 (hex)
Disabled
01E0FE00 (hex)

Differences (enebled -> disabled)

Bit 12 (0 -> 1)
Bit 25 (1 -> 0)

Offset 6C

Enabled
03E0EE00 (hex)
Disabled
01E0FE00 (hex)

Differences (enebled -> disabled)

Bit 12 (0 -> 1)
Bit 25 (1 -> 0)

For more information see this (page 84):

http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/26094.PDF

Looks like it is not that esasy to figure out. It would be interesting to see what happens with different configurations (1x512MB, 2x256MB, 1x256MB, different slots ....)

Hi, I enjoy using your a64 tweaker! I do have some questions:

1. how do you make windows load with startup settings? It doesnt work.
2. why does it sometimes default to loosest timing values? bug?
3. how do I change async latency in the bios of my gigabyte s939?
I am getting tired of manually changing it to 7 everytime windows loads cause the default of 6 isnt stable

"PLEASE HELP US MR. RED!" :(






Gents,

I've just found a way to really boost your A64 performance using WPCREDIT.

The A64 mem controller registers can be accessed using WPCREDIT using Bus #0, Device #24, Function #2. There are 4 main registers that I have been playing with:

0x88 DRAM Timing Low
0x8C DRAM Timing High
0x90 DRAM Configuration Low
0x94 DRAM Configuration High

The timings registers set all the DRAM timings params (as you'd expect), but there are many more than most BIOSes will show you. The best performance is obtained using:

Column Address Strobe # (CAS) = 2.0
Row Cycle Time (Trc) = 8
Row Refresh Cycle Time (Trfc) = 12
RAS# to CAS# delay (Trcd) = 2
Row to Row delay (Trrd) = 2
Min RAS Active Time (Tras) = 5
Row Precharge Time (Trp) = 2
Write Recovery Time (Twr) = 2
Write to Read Delay (Twtr) = 1
Read to Write Delay (Trtw) = 1

I normally write this as 2-8-12-2-2-5-2-2-1-1 for convenience ... not that rememering all those values is easy.

To set the mem timings to the above values change the registers as follows:
reg 0x88 to 0x02522311
reg 0x8C to 0x00000B00
(use 32 bit mode in WPCREDIT)

I have only begun to experiment with the Config registers but some of the things I have tried are setting the Asynchronous Latency Value (controlled by reg 0x94). Normally my BIOS sets this to 7ns, but when I dropped it to 4ns there was a healthy boost to my memory performance. To do this set bits 0-3 of reg 0x94 to 0100 (binary) (4 for those who cant read binary).

Just to make things more interesting, bits 22-20 of reg 0x94 control the DRAM speed (200, 166, 133, 100 Mhz). There are several reserved values, and I decided to try 110. Surprisingly this gave me a mem speed somewhere inbetween 200 and 166 MHz. This may be a 183 Mhz mem option I need to test some more to confirm these results.

Oh, 2T is also easy to disable :D

We no longer have to worry about BIOS updates, its all there in the DRAM registers. Over time I may write a simple windows app to set all this up in a user friendly fashion ... just need to find the time.

Only thing I cant do is set the bank interleave. Doing so would reorder the physical memory locations ... not something I think windoze would be happy with :p:

Try it and compare your before and after benchies with something like pifast or superpi and you'll see the boost.

v0.60 Beta is up! (http://www.cranox.com/Software/A64-Tweaker/A64Tweaker_V0.6beta.zip)

Code, I love this program you’ve created and I use it all the time, but there are many of us who are having a major issue concerning its accuracy versus the Memtest86+ v1.6 program. I came over here from the DFI-Street (http://www.dfi-street.com/forum/index.php) forum because we are fresh out of answers there. A specific debate is brewing as to which program, A64 Tweaker v0.60 Beta (http://www.cranox.com/Software/A64-Tweaker/A64Tweaker_V0.6beta.zip) or Memtest86+ v1.6 (located in the BIOS of the DFI LANPARTY nF4 MoBos), is reading the tREF (http://www.dfi-street.com/forum/showpost.php?p=263127&postcount=29) (click on the green tREF please) properly. Here are both the tREF Table and the tREF “Discrepancy” Table. I created them both and have posted them over at DFI-Street (http://www.dfi-street.com/forum/index.php). A link to my tREF Table thread will be included in the tables themselves:

As you can clearly see on the tREF "Discrepancy" Table, the only two places where A64 Tweaker v0.60 Beta (http://www.cranox.com/Software/A64-Tweaker/A64Tweaker_V0.6beta.zip) and Memtest86+ v1.6 agree, are in the highlighted blue sections. Now you can see why this is an issue. Not only because my tREF Table is based on your program, but because ALL the other simple tREF Tables, everywhere on the internet, are based upon your A64 Tweaker program. I cannot state, explicitly, that either program is wrong; I simply do not know the answer to this problem :shrug: . There is, however, a British guy over at DFI-Street (http://www.dfi-street.com/forum/member.php?u=3800) who keeps challenging the validity of my thread's claim because he professes to "know" that your program is wrong! He sites his belief that A64 Tweaker v0.60 Beta (http://www.cranox.com/Software/A64-Tweaker/A64Tweaker_V0.6beta.zip) is invalid based solely upon the only “proof” he provides, which is that programs like RightMark Memory Analyzer, Central Brain Identifier and of course, Memtest86+ v1.6 all agree with each other, but disagree with your A64 Tweaker v0.60 Beta (http://www.cranox.com/Software/A64-Tweaker/A64Tweaker_V0.6beta.zip). I am not so quick to jump to this conclusion the way he is, however, because it is obvious to me that since all those "other" programs corroborate Memtest86+ v1.6, they are plainly reading the tREF (http://www.dfi-street.com/forum/showpost.php?p=263127&postcount=29) data in the same manner. Given that A64 Tweaker v0.60 Beta (http://www.cranox.com/Software/A64-Tweaker/A64Tweaker_V0.6beta.zip) is reading the tREF (http://www.dfi-street.com/forum/showpost.php?p=263127&postcount=29) data differently than Memtest86+ v1.6, it obviously won't correspond with those other application's readings. Can you please help us by telling us which one is accurate and which one is in error and why, or if neither one is wrong, why there is this discrepancy? Thank you very much CodeRed :) .

I just hope that CodeRed looks into this for all of us. I also think that CodeRed is a great programmer too :kissbutt: . Just so you know RimRam, to my knowledge, EVEREST only shows a refresh as is preprogrammed on your DIMM as it is reserved in the RAM's SPD. It is Memtest86+, Central Brain Identifier and RightMark Memory Analyzer that conflict directly with A64 Tweaker. EVEREST, like PC Wizard 2005, only displays the Serial Presence Detect, EEPROM that is right on your memory stick. The tREF I am concerned with is the one that can be adjusted in your BIOS on your MotherBoard. I also would like to point out that I know for fact that A64 Tweaker is 100% correct on all the other data it displays. The tREF is my only concern here.

I am now officially extending a request to ANYONE who may know the answer to this problem, or perhaps has a different spin on it, to let us know by posting a response in this thread. Until further notice and until this matter is cleared up satisfactorily, I shall display two versions of my tREF TABLE. One shall be based on Code's A64 Tweaker and the other on Memtest86+. I shall also include the tREF discrepancy Table between the other two and my TUTORIAL Table shall be exhibited at the bottom. Once this issue has reached an acceptable resolution, I shall remove the Table that displays incorrect data, should that be the case. Hopefully, there is someone out there who can assist all of us with this. Thank you! Peace :D ...

I've never had any issues with other programs reading the "Tweaks" I've made while using A64 Tweaker, and the BIOS always reverts back to its original CMOS setup, from an A64 Tweaker adjustment, upon reboot. The A64 Tweaker's conflicting tREF data is always consistently there, however.

Hello everyone and Code Red,

I have a problem I overshot one of my values and after my system locked and reboot now all my tweaker values are the values at the bottom of the drop menus and it wont let me change anything. Please help me anyway you can I'm very good at all tweaking just below this level any help would be greatly appreciated. I'm using the .60 version.

P.S. Sorry been awhile since Ive asked for help. Yes I've reinstalled. Not sure of anything thing else I should have tried or left out.

push eax
push edx
mov eax,0x80002184; eax=Bus0Dev2Func1,Offset 84,85,86,87
mov dx,0cf8 ; set dx as adress port
out dx,eax ; send the address to IO Space throgh dx port
mov dx,0cfc ; set dx as data port
in eax,dx ;Receive the data into eax for the address we sent through dx port
and eax,XXXXXX ; Change the data
or eax,XXXXXX ; Change the data
out eax,dx ; Send back the modded data through dx port
pop edx,
pop eax

The assembler code looks really interesting and this idea is similar to the ROMOS project.
