ABit KT7A 3R BIOS ... Need modification desperately to lower temps

[Pitspawn]

Ok, I changed to the new bios. I liked the new features and stability. BUT, the temps on my rig are really borderline for my processor, every degree seems to count. This is kinda weird considering my temps are...

36ºC Idle and 40ºC Max Load (Prime 95)

I honestly think it has something to do with the PSU because it is weak and I never had stability problems before I broke my decent 250W.

Anyway, I need information on that one bit modification for the 3R Bios to lower temps back down to the WW Bios temps. AND I want to be 100% sure that my rig isn't going to get junked from this hack.

bump. I need help on this one guys, my system is unstable.

You need to do the Register 52 edit using WPCREDIT and WPCSET. Info can be found at www.viahardware.com under "Paul's KT7 Faq".

I just downloaded 3R too and my temps are almost 7 deg.
higher than usually. I am having different problems though.
When you get a chance, can you take a look at my post and
see if you have any ideas. Only when you have a chance!!!

AMDGuy, I thought WPCREDIT and WPCSet were just for windows. And I already had that register set before 3R. Did that bios update overwrite that?

snookhook, will do.

I hate to throw rocks at the "Temperature Temple", but has anyone considered the fact that perhaps the "halt-on-idle" feature, which 3R disables, is the cause of instability in ABIT mobos and that might be one of the fixes intended to happen with 3R?

I ask this question because, if I intentionally choose an OC that crashes at the Windows desktop, it always crashes right after "halt-on-idle" kicks in.

Well this bios really messed things up stability for me, I know that for a fact. It did seem to allow me to get into windows at real friggin high clock speeds. But the moment my comp hits 40ºC and above, I get nasty stability problems.

I really dont give a crap what speed I run at, all that matters is that I'm 100% stable especially when playing demanding games. That bios hack did squat, I think your right Hoot, the new bios disabled that halt feature. Oh btw, congratz go out for you Hoot. All the posts I read seem to have a comment from you. You know a frickin lot

Oh yeah, not relating to this thread...Today was hot in the UK. It was like 28ºC when its normally <20ºC. I had serious stability problems, so I did a bit of quick modifications. Because my psu has vents on the side rather than the bottom, I turned it sideways to suck air from the processor. Dropped load temps by 1ºC. So I then chucked the voltage down as far as possible while staying stable. Lowest I got to was 1.69v for 1100Mhz. Not bad, took like 5watts off heat production meaning another 0.5ºC saving. Still not good enough. Shame I cant afford a better psu, I would buy a new one in an instant otherwise.

If I knew alot, I would never have installed 3R in the first place. Though lesser speeds seem more stable, I can no longer run 10x150 or 10.5x145 at any voltage. It gets weirder from there. I try to run 3D Mark 2001 and can't get out of the first test anymore. Used to screem all the way. Tried reinstalling 3C and my trysty YH, but no change. Back with 3R now. Figure if I stepped in it, I might as well walk it off. ;D

I have the KT7A-Raid board, theres to weird things happening

I keep gettiin lockups; My cpu is 1.3GHZ with a ThermoEngine cooler set at 10x133 (I think this is right) and my temp is idling at 39-43c ;p , just ordered a delta fan and AS2 hope this will solve the temp problem.

also I tried to get the new bios but cant find it on abit's website were do i get it from? :'(

I'm thinking about going back to Bios WZ, because my temps
are skyrocketing with 3R.

Me and AMDGuy went through all the beta Bios 3R-b01-b03 and I know I personally thrashed the BIOS registers up one side and down the other. With the official 3R Bios release I have been unsuccessful in Getting the Halt command to kick in with the Register mod "52" "EB" its bit 7 in register 52 is the key but with this new BIOS. I have a quick boot and more stablity but more heat at idle. I leave SETI running 24/7 and my temps when under load with SETI and not are not significantly higher then idle. I personally suggest if you like the register mod to work not to go with this BIOS.. There pluses and minuses to 3R. vary from each configuration. If you like low temps at idle anything but 3R probably will do that trick.

I downloaded WCPREDIT and WCPRSET and modified
register 52 from 6B to EB. The only thing is that I had to
bump my cpu down to 1.333. I did in fact see a big difference
in idle temps though. At least their not up in the 50c range
anymore. If anyone knows of a fix for the 1.4, let me know.

 

[Pitspawn]

I think I got my computer stable now. It hasnt crashed in a week and I havent reseted for 3 days now. Its becoming an obsession now. I check temps every ten minutes, if I see temps getting to 40ºC again I run to the windows and doors to cool my comp down

Whats this about the 1.4Ghz fix?

 

[M@€$†®Ö™]

A update ! I wiped the OS and tried the mod to the registry again and it took like a champ. At idle I am running at system temperature.and CPU temp which are the same Which is currently 77 degrees fahrenheit. I am tickled. I have 100% stability and no issues with any conflicts anymore. I personally have found the optimum setup for my present hardware setup. Since everything is working perfectly its time for me to go messing again. Time To tweak that 1% of performance from this system

With previous BIOS versions ABIT set a bit in the BIOS CMOS (offset 52 bit 7) to "1" to enable the ACPI "HALT" function and cool down the CPU temp in idle mode. This, whilst allowing cooler CPU operation, is against the advice of AMD and VIA. Under earlier AMD processors, however, this modification allowed the system to idle cooler and had no ill effects. However, it was been found with newer 133MHz FSB processors running at 1333MHz and higher, that this software cooling can cause severe stability problems - especially under Windows 2000. As a consequence, in all ABIT BIOS releases after version 3R, ABIT have set this bit to "0" - the value recommended by AMD and VIA. This allows the motherboard to be stable with all AMD processors at the expense of an increase of 5-10 degrees Centigrade during idle (from approximately 35 degs C to 45 degs C). This will not harm your motherboard or processor. Note that this CMOS setting is widely used by other KT133/KT133A based motherboards. Note that if your processor is slower than 1333MHz then you can revert to the previous setting of the BIOS by using H-Oda's WCPREDIT and WCPRSET programs to modify this register value. If you are using Hex mode in these programs then change register 52 from 6B to EB to re-enable the software cooling. See downloads page for programs.

This is what I followed and when I reset my cpu back to 1.4, it
started to make a whinnying noise. Then I backed it down to
1.333 and it stopped. At 1.333 I definably saw a difference
in temps, but I want 1.4. I guess I'll live with the temps in
the 50's. The post says it will not hurt the cpu. I hope not!

I have gone back to 3C after playing with 3R for a few days. I can assure you that running Prime95 Torture at full priority, the temp is also higher by about 4-5C under 3R. This only goes to prove that Prime95 Torture still benefits a little from halt-on-idle. 3R has not allowed me to to OC any higher than 3C. I like the milder temps.

I just wanted to know if 3R eliminates the following Bios setting?
Under Adv. Bios Features.
CPU LEVEL 1 CACHE
CPU LEVEL 2 CACHE
CPU L2 CACHE ECC CHECKING
Because they weren't there!!
I went back all the way to WZ to get my temps, but now I'm
thinking of 3C. Does 3C have these settings and the stability?

 

[M@€$†®Ö™]

The 3 Settings are Enabled and Enabled and Disabled. The ECC checking does nothing useful. And the first 2 are Automatically enabled in the Bios as I can tell..I have not had any problems with 3R I guess others have well good luck I am happy and stable I modified the registers in the bin to suit my needs. Nothing ventured nothing gained I now have a ACPI option to Enable and Disable and the EPA Logo to turn on and off at my leisure through softmenu 3 and many other things MODBIN6 rules So I have the best of both worlds overclocking stabilty and cooling
