Whats causing this problem?

[ToejaM]

If I set my multiplier to x47 I get 4.7Ghz but running it under prime, the multiplier changes to 47 for about 3 seconds and then changes to x46 and stays there. It doesnt do this when loading other applications and programs. I've yet to try/check with BF3 which I'll do now. I was wondering what the issue is?

I have that speedstep tech on so that the idle power consumption is better and I'd rather not take that off.

Idle voltage 1.336 (1.335 set in bios) and underload voltage 1.312v.

Any ideas?

There are power limit settings in the bios, if it hits those then it throttles back. Just up them out of the way

 

[ToejaM]

Really not sure what I'm supposed to be looking for. I cant find any limits in the bios!

 

[weird_dave]

look for short term power limits, not familiar with your mobo but click any advanced buttons
You should find 2 power limits, one for short duration, the other long(?? brain fail) up them out of the way. I just put them at 300 which is way OTT, but it doesn't matter

 

[ToejaM]

I thought I'd cracked it with "Overspeed Protection" but its still doing it. I cant find anything like "short term power limits" and such

Anything else it'd be called? Under power management in advanced there is a "EuP 2013" what ever that is

I hate people (me in this case! ) that don't try and give the best information to people who try and help others so here, I think these are all the suitable menus. If you want to see another one let me know but I dont think the others are relevant.

First Bios Screen

Settings Button

Advanced

Power Management Setup

From the main screen to overclocking

CPU Features

From the main screen to green power

I hope that all makes sense

 

[weird_dave]

I downloded the manual, page 35:
Long duration power limit(W)
Short duration power limit(W)

This is under CPU features, near overspeed protection

 

[weird_dave]

There sems to be a number of things missing from CPU Features

54oC at idle... not a problem?

 

[ToejaM]

That temperature is so wrong its actually giving me a hernia I get about 75-79 under prime. 64max in bf3 and it idles at 40c. This is on a lanboyair + arctic freezer pro rev2 (rubbish I know but I think thats pretty good going). I'll be upgrading to a h80/100 when I can and clocking it up some more once I figure this out.

I think I need to update my bios tbh, I've tried though and it has a fit/doesnt work the way I tried so I gave up. Never had a bios update problem in the past.. MSI is just backwards and I just cba to work the bios update out.. and seeing as its actually stable.. I dont think updating it is needed other than for maybe this throttling its doing.

 

[ToejaM]

I know thats 10minutes but tbh I'm not running prime for hours on end like I do with games. Not bothering with a full run untill I get a new cooler so I'm happy with that

Infact I'm not doing anything now, I'm gunna leave it running.

Edit:

Seems fine ;D

 

[ToejaM]

Right so now I'm on the latest bios and I still dont have those features under the CPU Features bit. Any ideas!?

Might aswell downclock for the moment, I'm pretty sure this is also what causes my boot to hang. Im gunna go try.

 

[ToejaM]

Great, now as I had a profile saved for 4.4ghz, I loaded that.. just out of curiousity to see if those extra CPU Features were there.. and well.. they were!

I checked my gfs comp, same mobo and she has the features to.. now with my current overclock of 4.7ghz they arent there and I've been through every option to see what was different and aside from a few unrelated options they are identical so i have no idea what the problem is.

I have however.. managed to lose the ability to change the cpu voltage in the bios.. the option isnt there, not even as Auto.. its just physically not there. What the hell!

54oC at idle... not a problem?

I assume you're referring to the 54°C shown in the BIOS?

That's not the idle temperature as none of the power saving features are enabled in the BIOS.

If you want to check the temperature then do it in Windows, load temperature being the most important.

 

[ToejaM]

Bah so I've rolled back to the previous flash and I got my cpu voltage option back and I have the cpu features, everything is as high as it'll go.. but it still downclocks it to x46/4.6ghz

Looks like either this bios version or the board its self won't allow the overclock to go any higher. I did manage on the newest bios to get it to stay at 4700 but it kept BSOD and no way (even control center wasnt playing ball) to change the voltage to compensate.. was getting 0x101 / 124 bsods.

Pretty disappointed now as I know this'll go further.. not that anything needs it at the moment.. I dont think any game out there even comes close to having the CPU as the bottleneck.. bf3 using 40-60% for me right now.

I'm tempted to just underclock it for the sake of energy consumption heh

edit: @weird_dave: what are your long duration power things set to by default can you remember? Mine is at 200 default, I've tried setting it to the max (255 for me) and for some reason it keeps setting it back to 200.. and if thats in watts.. I thought the cpu only had a draw of 95 (before overclocking) and I cant see it hitting 200w.. or am I wrong?

Looks like this board isnt so good afterall.. alas cheap board you did me well until I got the OC bug!

 

[weird_dave]

Sorry, been away for a bit....
I'll take a reboot and look at my settings.

95W is the rated maximum, HWMonitor tells me mine hits 130W under load

edit:

short and long duration are set to 300, as is core current limit.

Are you clearing the CMOS after flashing the bios each time?

 

[ToejaM]

No I havnt actually.. I'll have to look into it, I'm not used to doing it by jumpers as I've had a button on my last mobos

Is it usually near the battery or in a specific place?

 

[weird_dave]

Yeah, it's usually near the bat. Not clearing it can cause problems as some settings change places between versions. mobo manual should point out where the jumper is
