M3A32MVP voltage info

[RoachHotel]

Hey guys, been awhile, but I finally got my 9850 BE, and have had some fun overclocking it.

The problem I am running into is I can only get this badboy to 3150. I will post a screenshot of cpuz to help. But I am wondering is if its possible that my nb voltage and/or my sb voltage is holding me back from clocking higher?
If I try and hit 3.2 in anyway. I bluescreen, or it wont go into windows. Doesnt matter where my frequencies are either, changed em all trying to hit 3.2, wont do it.

If I need to change my nb and sb voltages what should I pump em up too?

thanks guys. Also my system is the same besides I am now running 2 gig of OCZ flex pc9600 memory.

im not to familiar with these things but i can say youve got a great clock outta that chip, best thing to do when increasing Volts is to go one step at a time while checking for stability and heat issues until you find your plateu. i think n/b Volts will affect your stability moreso than s/b

G/L and keep us posted

Well, how does this work? Gets you a little higher FSB but around the same clock speed.

Makes we wonder if its the board, the processor, volts. I think it is likely volts, or perhaps the HTT is getting too high.

I found out the hard way that the HTT Clock is actually a multiplier that is based off your FSB setting. So, 1000MHz is x5, 800MHz is x4, 600MHz is x3, and so on. Stock speed is 200x5 for 1000MHz.

BTW, have you read this thread, it is about 9850 BE Low Voltage overclocking (or rather Low CPU Voltage):

http://forums.techpowerup.com/showthread.php?t=58746

Leads me to believe, I would watch the volts on the CPU, push 1.4 or 1.5 if you have to but really watch your temps....

 

[RoachHotel]

So jb, are you saying to lower the HTT speed some, then keep crankin? Sorry I am only a month old doing this.

I have actually got this thing to 3.150 total, but not stable enough to run any benchies.

Thanks man and great info.

Also my temps at 1.52 volts have never taken my proc over 51C. I think thats good considering how much voltage I am running at times.

I suppose the most common question I didnt ask is. whats the stock voltage for the NB and SB? I can take it up a small notch at a time and see if that helps also.

Thanks guys

 

[jbruneau]

Stock volts for the NB and SB on this board are both 1.20v, and the HTT is 1.30v.

Yeah, that would be my idea, drop the HTT and push some extra volts to the NB/SB/HTT, and see if its the board holding you back or if the CPU is actually topped out.

There are a rare few peaking in the 3.4 to 3.5 range, most are sitting between 3.0 to 3.2, of which you are on the higher end of that scale right now.

I would love to see more, honestly ! As I am sure you would too !

 

[RoachHotel]

Thanks man.. I was afraid to change those voltages becausse they are both Auto or what you sent them too. No other choice.
I can get it to post at 3150, but thats it. And it doesnt last long before it hangs. I am thinking I can get a solid 3.2 or 3.25 and be able to run some bench marks. Hopefully start beating up those Intel guys.. LOL

Thanks.

 

[jbruneau]

Apparently, most people are thinking that the holdup on the clock speeds aren't an issue with the processor, but rather a limitation of the board.

Perhaps look for a BIOS update from ASUS, or maybe even Beta / Custom BIOS.

No problem, don't worry about it, RH ! Glad to help!

 

[jbruneau]

At your 225, I think you could leave the HTT at 1000MHz (or x5), and just push the volts a little.

Take everything and add 0.10v to each of them:
HTT 1.40v
NB 1.28/1.30v
SB 1.20/1.30v
PCIE 2.0v

Try to see if that stabilizes the board. If it does, kick the HTT down to 800MHz, and try to push the FSB/CPU harder. Watch the volts and temps of the CPU, I know you are pushing 1.50v right now. Use CoreTemp to do so, OCCT also has temps built into it, if you are using it for stress testing (great program actually )! If you are getting into the high 50's and low 60's you need to lower the cpu volts, or get a better cooler on there.

Oh, and, once you get it stable at a higher clock speed *here's hoping*, drop the CPU Volts until you can find the lowest possible stable voltage. It will keep the system much cooler!

I would love to see you hit 3.2 or even 3.4 !

Are you OCing in Bios or using AMD Overdrive (AOD)?

I have been leaving the Bios set to auto for overclock and running AOD.

With it I select to OC each core alone and have noticed Core2 & Core3 don't OC as well as Core0 & Core1.

I OC them as follows.
Core0: 3.2 ghz, Core1: 3.3 ghz, Core2: 2.8 ghz, Core3: 2.9 ghz.

You may have to play around with it and see which core or cores maybe holding it back, if any.

But I also think the MB is holding us back, a Bios update would be nice to help us out.

 

[RoachHotel]

I am overclocking in the bios.. I didnt think about individual cores though.

Something else interestiing. For my NB voltage it give me 3 choices, I cant remember them all, but one if HTT voltage. Also the SB will not let me change the voltage at all. Its on Auto, and it wont let me change it.
Actually JB I would like to hit 3.4 semi stable enough to run a couple bench marks like wprime and pifast. I am right on the heels of the q6600's clocked at 4.0 or higher. I think I can start putting the smack down on those Intel guys if I can muster a bit more.. lol

Its all in fun though.

Thanks guys all good info.

It should come up something like this:
*Defaults after dash, Suggested in brackets*

Northbridge Voltage -- Auto (Manual)
HyperTransport Voltage -- 1.30v (1.40v)
Core/PCIe Voltage -- 1.20v (1.28v)
NB PCIE PLL -- 2.0v (2.0v)
Southbridge Voltage -- 1.20v (1.28v)

You seem to be running great cooling on it. I wouldnt tinker with upping the volts until you max out your FSB (meaning you take your cpu speed up until it reboots multiple times, bsods, or doesnt boot at all). Then Id start tinkering with Voltages. Also, Id bump down the HTT to maybe 3x or 4x to be safe. That way you wont hit that ceiling while you oc. Also, make sure you keep your memory on a divider if need be. That will also hold you back, no matter how good it is.

 

[RoachHotel]

Thats whats funny. Im not sure what my FSB max is.. I have had it all the way to 1220, and depending on the other multi's it may or may not boot. 225x14 at 1.52 volts is as high as I can get it.
If I change the multi, or FSB it will not boot. Its like the board is maxed.. Hard to explain because I am still farely new at this. If you can give me some examples of multi and FSB and/or voltages I will try em and see.
I can tell you at 1.53 volts I have not gone over 51C. So my cooling seems to be very good.

 

[jbruneau]

So, are you saying that if you lower the multi from 14 to 13, it will not boot at 225?

That would be a very odd issue, considering the stock multi is 12.5!

Can I say, BIOS issue again?

 

[jbruneau]

What he is saying is to kick the CPU Multiplier back down to the stock 12.5 or 12, kick the HT Link Speed down to 800MHz (x4) if under 250FSB or 600MHz (x3) if over 250FSB, and keep your memory at DDR2-1200. Keep the volts as mentioned in post# 13.

Push the FSB Frequency up 5MHz at a time, until the system will not boot anymore. I mentioned in post#3 that if you can hit 250FSB you will be running 3125MHz on the processor, and 2000MHz on the HT which is its stock speed (with the link at 800MHz or x4).

 

[RoachHotel]

Wow, I have alot to learn.

Ok wish me luck.. Gonna give it a try JB..

 

[RoachHotel]

ok it hated that.. no boot. what is the stock HT link speed? I tried setting it to 800 and 600. no boot. I am wondering if I need to change the NB frequency also.
I will keep trying. I will also post some better info, sorry for the sketchy info, you guys are great for helping me.
Thank you.

 

[jbruneau]

The stock HT link speed is 1000MHz.

When the BIOS says 1000MHz it is talking when the FSB is 200, too bad the number doesn't update or change as the FSB increases! The 1000MHz is actually a multiplier to get from 200 to 1000, so, in the case of stock x5.

Examples: When the FSB is 225, and the HT link is at 1000MHz as mentioned earlier this is setup as a x5 multiplier. So, 225x5 would be 1125MHz, compared to the stock 1000MHz. If the HT link was changed to 800MHz this would be setup as a x4 multiplier. So, 225x4 would be 900MHz, compared to the stock 1000MHz.

Usually you can get the HT to run a little faster than stock, though, a small bump in voltage may be needed to keep the HT stable. No more than 0.1v or 0.2v.

 

[RoachHotel]

man dude, once you get some good cooling, youre gonna kick butt on here.. This is great info, and I really appreciate the time you are taking to try and help me.

I thought the HTT is different on 9850BE. Is it not 2000Mhz HTT (or 4000Mhz system bus) for this AM2+ Cpu as against regular 1000Mhz HTT speed for X2 cpu? How is it in the HTT multi link? 1,2,3,4 and 5? I just finished build 9500 cpu on an ECS A770M-A (Thinking of calling of my sale on M3A32MVP wifi and use it). The ECS has 200, 400, 600, 800, 1000, 1.2Ghz, 1.4Ghz, 1.6Ghz, 1.8Ghz and Auto. I believe 9850 will have one more option 2Ghz (which is 4000HT). Check AMD's website. All other X4 are 3600HT.

My 9500 is @ 228*11 @ 1.23V with Auto HT link. Went upto 235*11 @ 1.256v. Boot into windows and can run some benchies but not completely stable.

So Asus bios doesn't look right. Did you update the latest bios?
