M17XR2 Overclocking Guide

yes it happens to me, you just need to o'c the one that is shown and the second one will be o'ced

try to benchmark or run gpu z and see

 

Yeah I tried that. It's shows in GPU-Z that the 2nd card didn't overclock when I overclocked the first card.

 

I can even get the AMD gpu clock tool to open says i don't have a valid device. How do i get it to work?

 

Looking for the best i7-940xm CPU Best O/C & Throttlestop Settings to use.
I know all CPUs will be slightly different. but currently in BIOS i am running at

%5 O/C
Vcore 75ma
RAM 1.5v
No Throttlestop (yet!)

Please post your settings

 

Don't up the Vcore unless you're having stability issues. The 5% BIOS OC is nice but doesn't do much in comparison to ThrottleStop. That's when you'll really wake that 940 up. I personally run 85/70 in ThrottleStop, but you'll have to see what kind of heat you produce when running your favorite program.

 

I've never gotten that program to work. Ever. You should reflash the VBIOS for the best results.

 

Thanks for moving post MOD

Are you running any o/c in bios then throttlestop 85/70?

 

No worries. Lots of info on post#1 as well.

 

FWIW, I run my system with just the 5% overclock and no vCore increase. Mine is stable with the 5% at stock, and the vcore increase just adds to the heat. Sometimes I'll use throttle stop, but not too often. No real standard settings. I mess with it from time to time. Mostly I used it for my benchmarking.

 

Thanks i have just change bios to 5% and its stable as a rock. When i get around to benchmarking i will try out setFSB hitting 20987 - 3Dmark06 with just 5% OC / Std GPU Clocks.

 

I just did everything specified in this guide. I have a few questions though being a complete noob when it comes to OCing and such

1. What are the default multipliers and clocks for the 940xm should I decide to revert the settings to the original?

2. What are the chances of this hurting my system? Running wPrime 32m I already saw the CPU temps spike upwards of 90 degrees C with these settings swiftly followed by a BSOD. Does this mean I should tame things down a bit?

3. Is there any way of setting up OCing profiles so I can set the multipliers and such more easily? Like a gaming profile and a non-gaming profile with normal clocks and multipliers?

4. Would an under-notebook cooling system reduce the heat at all? Also, would it be worth my while to perform the clip and thermal paste mod to my video cards with their increased clock (and by that argument temps as well) and CPU with these settings?

Any help would be greatly appreciated. I want to get the most out of my system without harming it. I'm sure my technical jargon is a bit rudimentary, but I hope I got my point across

1. Original Default Multiplier is 25x 2.13GHz (I think thats the clock speed) Once you restart you computer, the CPU will automatically be reset since throttle stop doesn't permanantly write to the CPU registers.

2. BSOD means you probably went to high with the multipliers and it BSOD because it didn't have enough voltage. The chances of damaging the CPU are decent if your letting it run at 95+ for extended periods. I did so on an OEM 920XM, and now it doesn't OC very high. At least I think I damaged it. Although I severely abused that CPU beyond belief.

3. With throttle stop you can save your settings. Once you open TS, it will automatically apply those settings. Here is where you need to be careful. You need to ensure those settings are stable. If not, then what you can end up with is opening TS will result in BSOD. The way around this would be to unistall TS and reinstall.

4. I would look at the CPU retention mod and applying some quality thermal paste. Especially if your going to be doing the cooling mods to the CPU/GPU. As far as a notebook cooler, it may help a little, but not enough to be worth it. Maybe a degree or two. I never saw much differance, but your experience mayt be differant. I use my cooler (NZXT Cryo LX) more as a stand then a cooler I never have it plugged in, but like the angle it puts the notebook at. Hope that helps.

 

Hello, I'm asking here just out of curiosity to see if anyone can offer me any suggestions/tips in pushing my i7 820qm farther than I've been able to already.

Using setfsb, I can get it to run at a stable 2.12ghz. If I push it to 2.13ghz, it will instantly crash. I've experimented with overvolting the cpu and the ram in the bios, and neither have made any difference what so ever in how far I can push the overclock.

The cpu temps are really low and stable, so that's not what's holding me back. Most likely that's the limit my chip can do, but I'd just like to hear any ideas or tips anyone might have on successfully pushing it farther.

Thanks greatly in advanced!

 

Hi guys,

I've been using SetFSB free version to increase my BCLK to 150 no probs - but it resets after every boot. How can I make it so its permanent? Or that its done automatically on boot? I can't find that option in SetFSB.

Thanks!

 

Anyone know what I can safely o/c my 5870s to? Apologies if it's already stated in here someplace.

Thank you!


EDIT:- also, AMD GPU TOOL only seems to allow me to O/C the one card - I have Furmark running so I can access both cards but GPU-Z is telling me the clocks only change for the one card - any ideas guys, thx.

 

starwars_fan Good to see you came here. I was the one to refer you over at overclockersforum. Check out the thread on the first mod bios for the m17x. The m17x. Thewiz unlocked the overclocking options for cpus that are not the xm ones. Previously the overclocking was only limited to Extreme CPUs such as the 920XM and 940XM. If you flash that spy can is the 5% overclock. Other than that setfsb is your other option. Pm me if you have questions. Ill be out of town those weekend and am tying this on my phone so sorry i can't give the mod bios link. Just search for " first m17x mod bios" and you should find it.

 

Hmmmm. I'm very new to this and the 5% overclock sounds like a good start. How exactly do I go about doing that? If I look in my BIOS now, the overclocking option is greyed out.

 

This is the modded bios you will need. To date no one has had a problem with it. Just don't mess work anything else unlocked if you don't know what it is.

A10 modded bios

 

Thank you very much. I'm going to hold off on it though, at least for now.

 

I've done the GPU OC #2 (with the AMD GPU tool),
Set the clock to be 700 and memory to be 1000 because they were lower (ATI 5870 CF) and I get this error:
"Can't SetClock, please check your settings".
And I can't set the clock to any value for both GPUs, only to the 1st one.

I've set the 1st one to 720 clock and 1020 memory and the 2nd GPU is just stuck at 100 clock and 150 memory.

So I went into a game to test it out and my laptop crashed after a minute.

GPU-Z was indicating that the OC was ok, including the voltage, only for the 1st clock and was saying that the 2nd one is 700 clock and 1000 memory, which is wrong by what the AMD tool was saying and what I was experiencing...

What should I do?
(Every thing is up to date, the drivers and vbios, etc...)

 

If you're having trouble overclocking your 5870's and would like an easier, more permanent solution, try This

Post #9 has a link to a nice program that will flash a new vBios on your cards, putting them @800/1100 each. Runs rock solid on my system

 

Using the shareware version of SetFSB I am at BLCK 172 @ 1860 Mhz no BSOD.

How do I know if its stable? Im afraid to go higher. How can I determine if SetFSB is really changing the clockspeed?

The only result that I can tell is that Crysis 2 is playing smoother now in 1920/extreme. How can I confirm the changes? Should I and how do I increase the voltage?

 

Crysis 2 froze up about 15 minutes into the game in the above settings, and

SetFSB was reset to the initial settings. I tried to go back to BLCK 166 at least and immediately got BSOD.

Voltage?

Any tips?

 

I reduced the BLCK to 166 at 1812 Mhz and am monitoring stability. Would it be ideal to run a stability test in Furmark?

Voltage?

How can I monitor the CPU temp?

 

My computer exploded!

 

Are you serious? What exactly happened?

Overclock with the bios mod instead http://forum.notebookreview.com/ali...r2-bios-mod-need-suggestions-future-mods.html

 

why you guys mess up with things without first having some knowledge about it? what you are talking about is CPU overclock. Furmark is intended to stress video cards (GPU). use Wprime or prime95 to stress CPU for stability.

 

I have been walking you through this in the many PM's you have sent me.

Once again:

Run Prime 95 to stress the CPU

Run Furmark 1.82 to stress the GPU

Monitor CPU/GPU temps using HWINFO32

Run GPU-Z to see Utilization of crossfire.


you can't just jump from one BCLK to another without going through some other BCLK's first you cant jump from 172 to 166 or from 130 to 166 you have to progressively get up there. I told you to not do it when the CPU is being UTILIZED as it will cause you a BSOD. You ideally should Slowly overclock when there is little to no usage of the CPU.

 

No Im only kidding, but I have recently switched to the modded A10 BIOS as original A10 wouldnt let me use SetFsb with much success. I was having an issue where I could OC' to like BLCK 171 initially @ 1.86 Mhz and then while stressing the CPU in game or Furmark I would get BSOD and then upon restarting I would progressively have to OC lower and lower until I was at BLCK 160 @ 1.78 Mhz and I just gave up.

I hope the new BIOS from WizKid works better.

Will flash my GPU's later.

Everything is ok.

 

same problem with new modded A10 BIOS, unable to OC' above BLCK 160 @ 1.76 Mhz with SetFSB, trying 150 mV but no difference. Every CPU is different, I guess mine is a bit weaker than average.

 

Well, I did it, i broke down and purchased a 920 xm from suzie on ebay, It turned out that the XF set up wasnt the limiting factor in the performance, looking forward to having a powerful laptop soon, 1920 and high settings galore.

 

Using the shareware version of SetFSB I am at BLCK 150 with no BSOD.
151 and more gives me BSOD.
I think it's a ram problem.
I don't know how much I can safely increase the voltage on ddr3?
or maybe better way is to flash ram from 1333 to 1066 to have more space for OC?

 

Could be a RAM issue, could also be a voltage issue. I know that I have volt modded my i7 540M to 1.4v for benchmarking, and it helped only a tiny bit, not enough to be worth it. Being a quad, I think 150 sounds about right. Try upping the voltage for the ram if you havn't. Also, up the voltage in the bios for the CPU if you don't already have it at +150mV. If you have that voltage stuff up, than its likely a voltage issue at the PLL, meaning your at the limit since the board doesn't have a PLL voltage control.

 

Thanks DR, I'll try.

I've got 2 more questions"

When I disable CF in CCC the fan still works. It doesn't turn off. Is it normal?

and the second one about OCing the GPUs
I always use trixx to OC the gpu. I tried 800/1100 but it crashed. I wanted to increase the voltage but can't see this option. It seems to be unavaiable.
So how to add some voltage on GPU? Only way is flashing the vbios?

 

I havn't used Trixx with the 5870's but the option should be below the graphics clock settings. Maybe you need to update your version of Trixx? I normally just flashed the 5870's so I couldn't say for sure.

As for the fan, That is normal that the fan still works.

 

+1 for help.
Thanks again

PS. Is there an application which allow to increase voltage on gpus or I need to flash the vbios?

 

You may need to flash the GPU's after that I suspect that Trixx will allow voltage control. If you want to overclock via bios flashing, here are the instructions I follow. Works for the 6900 series cards and 5800 series cards as well. Just remember under voltage you have to type it in. 1.15v is the max. Anything above will result in BSOD. ALWAYS keep a copy of the stock vbios on the usb stick so if something happens you can flash to stock if you get BSOD. Just copy the stock vbios and edit the copied file. I normally will creat several copies so I can just flash and not have to go back in and re-edit. You only need to change the 3D Clocks as well.

 

I increased the voltage of ram and cpu and could only get 153 and it seems to be the end.
Maybe flashing the ram to 1066 would help. There is spd tool. I'll try it.

 

guys i have a problem.
My 920xm. i set 5%bclk 25*140,333=3508 MHZ
throttlestop: 105
90
im just getting 16500 cpu in vantage i see guys here with 22000 with the 920xm
can it be because the 5870m is to slow? but then what has the cpu test to do with gpu?

gpu is 5870m @800/1100

Please help

 

16000 is normal. The 22000 scores are highly overclocked systems. Thats not the norm. GPU has nothing to do with CPU score.

 

but i played around with throttlestop 90/75at 26*133 0%bclk =3,45 Ghz
i got 19300 Cpu score how??

 

yeah!!
105/83 0bclk 25*133=3,3ghz no volt increase, no mod
5870m 800/1100

i got vantage p10500 cpu 20526 gpu 9200
3dmark06 p16300

 

What are your max temps at 105/83?

 

hi
i played sc2 yesterday and had hwinfo open
at the end max was
71C on core1
62C on core4

watt usage was 50watt

gpu stock5870 was 70C

 

just imagine 2*hd 7990+920xm+rgb-led

i love the fact that the new gen cards uses less power then previous gen

 

Im assuming thats just one 5870?

Dual 6990s would be good enough for me. Heck, even these dual 5870s ive got are good enough for everything i play at the moment!

 

yes youre right just one 5870 stock

i said that because im happy that with 2*7990 i could use my rgb-led for many years

 

Can't keep 5% factory overclock applied. Do I have to raise the multipliers? After about an hour of gaming the clock speed resets to the default. I also raised the vcore to 150v in the bios.

 

FSB reset to stock 133Mhz is a common issue. Whenever the laptop goes or it is put in stand-by for example, after resuming the FSB will be reseted to stock. That's why is much more convenient to work on the multiplier rather than the fsb.

EDIT: you shouldn't need 150mv for only 5% OC....

EDIT2: i didn't notice you have a 940xm... sorry my bad...

so, the R2 bios will keep that chip at 25x133 across the 4 cores, this is the way it is designed to work the xm in our AWs. This being said, once you apply also the 5% OC from bios you are running 25x140 across the 4 cores... wich translate in 3.5Ghz, this explain the need for overvolt. My 920xm for example needs 75mv in order to be stable @3.5Ghz. No problem of stability @3.33Ghz stock voltage

 

Mine requires .75mv to be stable at 5% oc too.

I haven't pushed my 940 too far for it to need .150mv - yet!
