Yes, but in this case we do not know what happened exactly.

I have already reflashed by Bios with the A13 but the problem is still there so there is no problem in the bios i think

Try to put them in cross, i had same issue when upgrading ram,they would not go together,try one under keyboard and one other side see if works,did for me !

i troubleshooted my PC, removed all the rams and inserted the working one in to slot 1 2 3 4, slot 1 and 3 booted up the PC but slot 2 and 4 gave 4 beeps on startup. any suggestions?

Make a backup of your main system bios and put out here.

Hi, I think we should try to stay on the topic of this thread mainly. I recommend you start a new thread or search google on your RAM problem. My only brief advice to you is to try re-seating the RAM.

Yep, I thought 1158 sounded a bit high, but I didn't want to challenge you on it! My previous advice still stands really, your temps aren't that low, I'd leave it as it is. But, do as you please, I think whatever you do you should keep the temperature below 80 or 85 degC if you're overvolting. Next step is up to you.

Well, that's entirely up to you! If that is your maximum core clock & memory clock then great. Temperatures look OK. Given how high your core clock is, I wouldn't bother upping to 1.05V, might give you another 40 or 50Mhz, but that's nothing on 1158Mhz! I think you should leave it there, no point in getting higher temperatures for the sake of an extra 50Mhz.

OPS sorry its 1058 :S my bad so yeh now what?

I think the 3740QM (Ivybridge) may behave differently to Throttlestop than my 2630QM (which is Sandybridge), so I can't really advise you on Throttlestop much because I have no experience on Ivybridge. There's a Throttlestop forum on here somewhere, I'd try posting on there.

I'd set it at 1.025mv. Then back the core down to 1007Mhz to be certain that the core is 100% stable. Then increase the memory overclock in increments (starting at 2200Mhz), while checking for stability using 3DMark11 or demanding games (Far Cry 3/Tomb Raider) that tax the GPU to 100% GPU usage (measured using GPUz for instance). If you see artifacts or crashing then you have reached your maximum memory overclock (the previously stable one). This is now your maximum memory overclock. At this point (while on 1.025mv) increase GPU core frequency in 26Mhz increments (13Mhz is one increment), and do your stability testing as before (3DMark11, games), to determine your maximum core overclock. If temperatures are good, less than 80-85 degC then you could consider further overvolting to get a greater core overclock.

Yep, I think your maximum memory overclock may have not been determined properly; there's no reason why you get a higher stable memory overclock when you have your core at 1.05V in comparison to 1.025V. It leads me to believe that you should do some more testing. It's possible that at 1.025V the core wasn't 100% stable at 1071, which led you to believe that your max memory clock was only 2200Mhz. The differences in maximum possible memory overclock don't make any sense to me there, I think you could do with some more stability testing.

Suggestions would be accepted

I have an Alienware m17x R4.

Yesterday one of my rams got busted and the memory slots 2 and 4 don't work anymore. i have tried installing a good mem stick in each one to check but 1 and 3 work but 2 and 4 don't. Please post any solutions if u know

Yes, maybe the extra heat & power consumption can cause your maximum memory overclock to become unstable. I would have thought that if you up the core voltage to 1.05V that this might make the maximum memory overclock even more unstable. Perhaps there's an ideal performance balance that you find between core overclock vs memory overclock. You could always determine your maximum memory overclockability by leaving the core at stock values, and then OC'ing your memory until crashes or artifacts. Then you could increase the core clock, and see at what point it crashes while at your previously highest determined memory overclock. Although I think gaming performance would benefit to a greater extent with core overclocking than memory overclocking, so I would suggest leaving the memory at stock, then overclocking the core until artifacts & crashes; then using your determined max core overclock I would then increase the memory overclock until instability & crashes. That's the way you'll likely get the best combination of maximum performance in games I think.

I have already done that so at 1.05 V i get 1100/2480 Its stable and at 1.025 1071/2200 which one to pick

Good job, you got some excellent overclocks there, pretty much similar Mhz vs voltages as mine!

My memory overclock has been the same for all of the overvolts I have tried, this is because the voltage you select doesn't change the voltage for the memory, just changes the voltage for the core. I have my memory overclocked to 1100Mhz, which is the actual Mhz the chip runs at. The way you've reported yours, if I were to report mine in the same way, then my memory overclock is 2200Mhz.

I've been doing some extended long term testing in benchmarks & games with different overvolts & overclocks to work out a range of long term stable overvolt/overclock settings, and I thought you guys would be interested in the results because it might help you work out your own stable settings.

First thing I noticed is that passing through a 3DMark11 benchmark run sucessfully was not a measure of long term stability. In fact long term stability was usually gained by dialing back core clock by one notch (13Mhz) after achieving a successful 3DMark11 run. Second thing, there seems to be a direct linear relationship between volts & stable overclock frequency; if you take a look at the attached picture you will see that the graph is linear, so that could be useful for you to use to help dial in your own further overvolts/overclocks

Hope anyone that reads this will find this useful or interesting!

EDIT: I was kind of flabbergasted at how linear & exact this relationship was!

Haha, that sounds funny, but dangerously unstable! I'm surprised it makes such a difference! Looks like you're onto something!

Unstable....well after 2 hours of intense load it only went up to 79. and during benchmarks it ran a cool 76 with clock now at 1100/2475....

I am using a portable fan as a cooling pad..temps don't go above 60 LMAO

Open GPU-Z>Read ASIC quality, nice sample you got 1070/2450 1.025v, for gaming 1006/2450 stock v. enough.

well i play max payne 3 and metro last light and those games free at 1006/2450..

right now they don't and with the 1100/2455 it was give me around about 40-50 FPS

I'm just a bit confused about your post, but it doesn't matter. The memory overclock is not affected by the voltage you've been manipulating, because you're just changing the voltage for the core clock, the memory voltage is set in stone. As for your core overclock, we've already talked about that, and the pros & cons of increasing that beyond your 1.025V.

the 50 MHZ is on the GPU clock..it does give me considerable performance because right now GPU clock won't budge from 1058

EDIT: Ah, it's OK, I re-read your post, and I understand it now. Well, you can choose whatever you want to do with the voltage, perhaps svl7 will do you that modded vBIOS you talked about.

Good luck :-)

I hope so. thanks for the help

10 minutes of Metro 2033 and temp back up to 88-89.. the laptop is elevated for ventilation but still.... high temps ..-,-

Ah, the memory clock is not related to the voltage changes that you've been making. The voltage you've been tweaking only changes the voltage of the core, not the memory. So your maximum memory overclock - it is what it is! However, I think I heard it was possible to do a hard mod to the GPU to increase the memory voltage, but that's pretty advanced (and risky), and I don't know anything more about that.

thing is the extra 10mv give me arounf 50mhz because the current clock won't go about 1058..so the voltrage is bottlenecking it...the extra 10mv can be like an experiment to see temps and if it works well and good if it doesn't back to 1025. but i just need someone to tweak the voltage. this can benefit the 680m users as well, to unlock their card to its full potential while remaining at suitable temps

Maybe svl7 can do you one of those, who knows. But, I don't think it would really be worth it for an extra 30Mhz on your core, because then you're pumping even more voltage into it with the higher temperatures, all for only 30Mhz.

true dat. i want to ask about about the memory clock, i can't seem to go higher than 2500 it just freezes and boom driver crash. what is this about...-,-

That sounds sensible, 1070Mhz is near-as-damn-it 1100Mhz, and you're saving the 25mv and decreasing the temperatures while you're at it. I'm not sure what you can do about the temperatures you're seeing beyond what I advised for you. The next thing you could do is maybe some mod to the cooling system & heat sink, but you'd have to research into what's possible with your specific laptop model, in terms of what other people have done. I can't advise you on that.

The temperature at this overclock stays round about 76-78C and my notebook is alienware m17x R4. i lose around 3-6 FPS my 3d mark vantage score for the GPU only is 31205. if someone can tweak a little with the voltage and make it around 1.035 it should be sufficient for 1100/2455 overclock at suitable temps. but the GPU clock doesn't go higher than 1058 on msi after OSD

I would say that temperatures seem reasonable considering 1100Mhz and 1.05V. That's a very good overclock! With the increased voltage you might see some decrease in the usable life of your GPU at those temperatures though. I know that some Kepler cards are designed to decrease their level of boost above 70degC, so I'm pretty sure that 1.05V will be fine under 70degC, but possible that silicon degradation may occur at a faster rate above that 70degC when combined with increased voltage. You can try minimising your temperatures by blowing out dust from the heatsinks using a can of compressed air, and/or repasting your GPU, and/or using a notebook cooler, and/or playing computer games in a walk-in fridge! I'd seek some advice in forums where other users have overvolted their 680M too. (also use the notebook on a flat surface so that the fan intakes aren't blocked).

I have over clocked my 680m with the 1.05 volt bios. i set my GPu clock to 1100MHZ and my memory clock to 2450..Its stable no crashes + glitches..But i am hitting temps of 87-89C. is it ok or should i worry about. if i should worry gimme a solution.

thanks

Haha, I think you mean 1.05V rather than 1.5V!? 1.5V is not safe, but I imagine 1.05V is quite safe, as long as temperatures are good.

Ops yeh i meant 1.05...

Is it safe to run GTX 680m 2GB at 1.5 volts..I know over clocking is risky but is it ok to update to this bios?

Hey. I am new to the flashing and over clocking community. I have an ALienware m17x R4 with Gtx 680m just looking to over clock this bad boy

Well basically GTX 690 are two 680s on 1 chip. But the 670 Sli has almost the same performance as the 690 but it has a disadvantage. it requires two cards, more heat more money... where u can buy one 690 right now maybe buy aother one later to make them SLis.....Will run every game on ultra..

Hope this helps
