4900mq 4ghz OC settings

Hi all, in the process of sorting my gpu out I did a bios reset and lost my 4ghz OC settings with the 4900mq, could anyone tell me the values to change in the bios? Or put a quick guide in what the different parameters are and why they need to change when OCing?
Thanks

 

Anyone with a 4900mq willin to post their OC values from the bios

 

In performance / Extreme option choose Bios and Ratio Limit - OV LV 1. Hit F10 and done...

 

There are no levels in the BIOS (level 1, etc.). It is different than the previous generation which may be confusing for some.

 

Thanks it worked good +Rep

 

Actually there is for 4900MQ. If you have a 4700MQ, this option is disabled. It works for me and for others as well...

 

Glad to hear it worked. Unfortunately it rises the temps even at idle when you have it overclocked (for about 7-9 degrees); my advice is to keep this option off unless you needed...

 

yea my temps go to 87 now from 83 under load, it was for benchmarking my physx score is going under 10k (9740) when before it was always over 10k on 3dmark11, what scores do you get with your system? at stock gpu clock

 

Sorry, I haven't done benchmarking in a while now... I use the overclocking option only when I do many applications at one time including photo editing, video encoding etc. etc., it helps a bit...

 

I've removed it, gpu started downclocking to 614 again, maybe a power issue cause temps were low

 

I don't see the levels in my BIOS.

Spoiler

EDIT: I have the 4930MX.

 

It was under the core ratio limits options on top of the highlighted option in the pic, btw I've disconnected the battery from inside, will that cause any problems?

 

Doesn't show the levels.

Well then most likely it's there for the 4900mq because it comes overclocked by Dell

 

Part of your screen is chopped off, so I am partially guessing at the menus, but it appears you have overclocking set to enabled.

If you have a 4930MX you should be seeing Level 1 through Level 3 overclock presets for "Extreme Edition Core Ratio Limits" and not simply the "Disabled" option. Something is either wrong or they did something to cripple the BIOS.

Try changing the override turbo settings to enabled and see if that changes other menu options.

 

Oh, crap, that's not good. I knew there was something wrong there... Suggestions?

EDIT: I sent you a PM with another picture with everything enabled. Still don't see any levels.

 

If you do not have an Extreme CPU (4700MQ, 4800MQ, 4900MQ) the Level 1 to 3 overclock presets might not be available. If you can change the multipliers for each core, it may not matter. If you can change them but they are capped with a 4930MX CPU like a non-Extreme CPU, then that would be a problem.

Disable Non-Turbo Flex Support. That should never be enabled. Maybe that is causing the problem. If 32 is not the default, it should be set back to the default non-turbo speed before you disable it. On an M18x it will cause it to fail to POST with switching from IGFX to discrete graphics if that is enabled.

Your Core Voltage Mode should be set to Adaptive rather than Override. 1200 (1.2V) is too much voltage until you hit about 4.5GHz and leaving it that high it will cause the CPU to throttle really bad under load with it set to 1200. (It does on the 18 I have.) For 4.3GHz you only need 1.165V-1.175V and it should be set to Adaptive mode for the best results. By best results I mean reducing the likeliness of a BSOD from using the wrong voltage setting.

So, from what I am seeing from your screen shot, the 17 BIOS might be screwed up a lot like the BIOS for the 18 is. If you load XTU, is the default Core Current Limit 32.000A? It is supposed to be a minimum of 112.000A.
