That's ASUSs' overclocking tool I linked Achim.
Reboot to see if Smart Guardian works.
Manual says Ai Gear helps to reduce noise and power consumtion. I expect it allows switching p-states, it has a three gear shift.That's ASUSs' overclocking tool I linked Achim.

Currently reinstalling windows cuz it won't work in cnq anymore (other os on different disc works). Will try smart guardian again when i finished the setup.
EDIT: Tried it on a fresh install (cnq works now). It requires to disable manual overclocking settings and does nothing, which is better than freezing the system. Tried it with cnq on and off in the bios everything else had to be auto. No frequencie voltage or power consumption change, not even the fanspeed changes.
Smart guardian does not work even after a reboot, That whould have been a nice way to change the vcore.
@jakalwarrior: Do you get an CPU-Overvoltage Bios warning when you set 0,85V in the bios. Have not tried crystalcpu for anything beside msr editing. Looking at your sig, you must have good cooling to run your 4000+ with such low voltages.

For me is the Asus M3A history!
Next week I want to test a brandnew E8200 Wolfdale + MSI P35 Neo2-FR ...
I think a better choice at the moment
I will give mine another couple of weeks and then if no voltage options exist it will go, and possibly the Phenom as well.
My old 5000be and mobo were not much slower and used less power.
pfff.. viral marketing trolls again... at least you could go beyond 10 post to tell us that Penryn+P35 is the better choice over Phenom+AMD 7-series chipset... you know it's all about credibility that you lackFor me is the Asus M3A history!

Adobe is working on Flash Player support for 64-bit platforms as part of our ongoing commitment to the cross-platform compatibility of Flash Player. We expect to provide native support for 64-bit platforms in an upcoming release of Flash Player following the release of Flash Player 10.1.
Just picked up the m3a32-mvp deluxe busy testing, so far very similar in performance to the m3a.
Uhm in that price segment i'd prefere the DFi board, but i'm just curious because i never had one. Have you compared the memory bandwith of the two mobos?
Guess I stay with 770 and grab the Biostar 770 A2+ if asus can not realize a vcore option in the bios or i'll be patient enough to wait for a 780G mATX mobo with sb700.
I'll build an intel rig with an qx6850 for a co-worker in a week or so. I'm curious how it's resposiveness and power consumption will compare to my phenom rig if I downclock that thing to 2,2GHz.

No memory bandwidth test yet just testing games so far, seems the wireless lan and vista dont like each other. Will keep you posted soon though.BTW this is my second m3a32 deluxe the first one would not start.
Did some research how vcore mods are done. So far I located and identified the voltage regulator chip. It's an L6740L and here is the pin-layout.
The specs can be found here.
Great, thanks. So you bought the M3A for the time m3a32 was in rma?No memory bandwidth test yet just testing games so far, seems the wireless lan and vista dont like each other. Will keep you posted soon though.BTW this is my second m3a32 deluxe the first one would not start.
I have seen no write ups on the Biostar board, might be safer to wait for the 780's. The only good performance reviews I have seen go to this board:

I plan to get one of those for a machine at work (together with an 6400+ maybe).
About vcore modding. According to this article, the next step is to identify the resistances connected to pin #4 (FB) and pin #33 (NB_FB) and shade those.
The chip is located next to the mobo's power plug, close to the cpu. Guess I must remove the heat spread connector to inspect this pins.
You mean the cpu cooler? Not sure what you mean by heat spread connector.I plan to get one of those for a machine at work (together with an 6400+ maybe).

Just be careful and try a 2hb pencil first. I have a 2hb and a 6hb, used the 6 on my g-card. I would rather you be the experimenter LOL.
Sorry, yep I mean the adapter for the cpu cooler.
I think I identiefied the nb resistance but for the cpu I'd need a camera. Used a normal pencil and shaded the nb resistance. AMD Power Monitor did not show a difference but I think that tool reports the vid's. So I try prime95 with lower nb voltages now to see if it worked.
EDIT: It did not work. Must wait till room mate comes home with a camera.

Well I emailed Asus engineering again this weekend since they never replied last time. This time I asked them flat out if they expected the voltage issue to be fixed.
This is really frustrating.
Did you notice disabling the TLB fix via AOD does not bring the same performance increase as disabling it via the Crystal CPU?
Found this in the specs. I think I shaded Rf,nb and not Rfb,nb.
Hope that pic will help identifying the right resistances once I have a few pictures.
I plan to mail em the bu list for 601 once I checked a few things I found with 501.
Makes me look into vmodding, so i don't mind atm.
I noticed a difference between yellow and red mode but aod's red mode.
To apply the fix with crystal cpu one must modify the two msr registers on all cores, otherwise only the first core will use the tlb. That might have an impact on benchmarks.
Hey ya'll I have the thread over on Legit, was wondering if any of you have ran water cooling on the NB? I just spent the week fabricating an external water cooling box and the cpu is water cooled (x2 6400 heat pump), the zalman NB water block is laying up on the PSU waiting and ready (after heavy mods to the now not so universal WB lol).
So far it's been a really good board with the X2, but had to wait on NB water cooling for a solution to the NB water block rocking on that tiny chip. Neoprene rubber hand cut is what I'm planning unless you have a better idea.
Flipped 450 FPS on a volt modded 8800gt under Lightsmark on the board. The only better I've seen is an 8800 gtx max oced under water and it crunched a 555 fps.
Lemme know if you watered the NB (safe/not safe) and if you used a gasket and if you did what material.
Much Appreciated!
BTW nice thread/forum
Hi Methious,
Linked your thread on the first post, glad you joined.
Can't help with nb mounting but I'd be interested in a good solution. I googled for nb waterblock mounting on the M2A-VM. This mobo uses the same nb cooling but did not find anything usefull.
I remeber somewhere in this forum was a recommendation about nb cooling on the m2a-vm, just have to find it.
I have two reliable sources, one an engineer that designs water systems for a living, and Bio-Hazard, if you Google "Monster Rig" or Bio-Hazard you'll get about 2 pages on him. One says 3M double sided tape with a window cut into the tape for the NB, the other says neoprene foam cut large enough not to cover the NB chip, but small enough the WB sets on it. (Watch upward pressure from the neoprene on the water block, so the fit has to be close)
I Googled the heck out of M3A NB Water Cooling, no luck. I finally came up with a Zalman universal I got on sale, it's not universal now, you have to Dremel off the the loops used for through the board installs, then where they used to be grind a little to fit it between the loops. Then due to poor capacitor placing cut the end of the hold down clip off right in front of the hole used for the loop hold down hook. Shame I was looking forward to using that water block on later builds. If you go that route be real careful they pull out of the board pretty easy.
If you want greater stability over clocking you can try video ram heat sinks thermal taped to the MOSFETS. Helped me break the 360 FSB wall with a 80mm fan blowing on the mosfets from the blow hole. Don't know if it's going to help Phenom users.
Thanks I joined because you all are doing some great testing and I had been cruising the forum looking for tips. I don't want to mislead any one about my water skills, I'm new to it, first water build after 25 years of messing with this stuff. But I found out that I had access to two people who had massive experience so my info comes from there.
I got the 6400+, don't know if I'd go that direction again. It's the hottest chip I've ever run, even under water, Swiftech MCP350 pump, Dell XPS 710 Rad, Swiftech Water Block, runs 30C idle, 40-42C load. Under a ThermalRight 120 Ultra, load ran 46C with upward creep, nMedia PC IceTank ran 55C load with a lot of creep. Runs like a dream though if you don't mind lack of OC overhead (probably not going there at work) Normal non-100% working load it runs pretty good.

Dont worry about temps that much. Whatever it gets with stock cooler at stock volts must be acceptable or AMD wouldnt sell it like that. They would lose too much money on RMAs (do they sell those retail with a warranty? AFAIK oem has 0 warranty now)I got the 6400+, don't know if I'd go that direction again.

The 6400+ Black edition doesn't come with a cooler, I got the retail version and ran it with the nMedia PC Icetank at first, that's a 92mm 4 heat pipe and under load wasn't sufficient, ThermalTake Volcano wouldn't touch it, ThermalRight 120 Ultra did a good job if you want a cooler the size of a child's shoe box in there that weighs upwards of 2 LBS. Zalman 9700 does a good job.
With coolers of that magnitude the only ones suitable for full load it becomes an issue. It's a 95nm design, more nm means more electrical resistance, more resistance means more heat. Take a look at the AMD site and recommended coolers for the 6400, then do a search for them, after an hour I gave up and got the ThermalRight.
Small correction Methious,6400+ is made on 90nm(not 95)
Methious, are those temps stock or oc results? Zalman 9700 was what i had in mind. Don't know if I oc that machine, if there is an more energy efficient point above stock i'll oc it to that point but not further. Looking at 6400+'s stock voltage requirements 1,35V-14V there is not much room left.
Currently I use the thermaltake big typhoon on the m3a. Does a good job in component cooling and the temps are about 3° above the reserator 1p with the reservoir outside in ~1-5° ambient.
Had an Zalman 7000 mounted before, with whom I had ~15-20° higher temps that with the reserator setup in the above 1,5V cpuv area.
You shoul put a picture for your nb waterblock on your legit thread, modding sounds adventurous.
Roommate can back with camera I will take pictures of the L6740L area now.
Hmm, not the best quality but better than my eyes.
@informal: BTW, tried the be2400 with the zalman 7000, max I could reach with load temps below 70° was 3,1GHz at 1,4V, close to 0,1V more cpuv required than with watercooling. So the 3600+ I have should do 2.8-2.9GHz max on air.

hi all id like to know is , is the asus m3a a good overcloker with the phenom 9500 ??? i dont realy understand all the high spec terms u guys are using , so a simple yes or no wud be great
