kazekai Posted May 6, 2013 Share Posted May 6, 2013 Haha yea, I thought so. But yea, for my first 750M boost 2.0 is still available Quote Link to comment Share on other sites More sharing options...

Amblin Posted May 6, 2013 Share Posted May 6, 2013 Hey svl7, while you are tinkering, can we get that vmod on the 650m? I'll know I'll definitely be tossing you some more beer money if you do. Thanks again for your hard work. Quote Link to comment Share on other sites More sharing options...
svl7 Posted May 6, 2013 Author Share Posted May 6, 2013 This should solve the 750m issues, report back.Files removed. 2 Quote Link to comment Share on other sites More sharing options...
kh90123 Posted May 6, 2013 Share Posted May 6, 2013 This should solve the 750m issues, report back.It works, thanks. Now I need to figure out the max OC and increase the vcore slightly. Seems like +200MHz offset is the max I can get without increasing voltage.What I don't get is that GPU0 and GPU1 are still showing different voltages. 1 Quote Link to comment Share on other sites More sharing options...
kazekai Posted May 6, 2013 Share Posted May 6, 2013 This should solve the 750m issues, report back. Works now, thanks! And as mentioned above, the two voltages are a bit off (0.806V vs 0.812V), but other than that, seems to be fine. Quote Link to comment Share on other sites More sharing options...

That's a driver or even more likely a monitoring issue, the voltage settings in the two vbios are the same. Quote Link to comment Share on other sites More sharing options...
kh90123 Posted May 7, 2013 Share Posted May 7, 2013 Ladies and gentlemen, I proudly present: NVIDIA GeForce GT 750M video card benchmark result - Intel Core i7-3630QM Processor,LENOVO INVALID score: P5280 3DMarks. The highest the SLI GPU would ever go is 1269MHz (+210MHz offset), with 1.175Vcore. It's possible that I could squeeze it to 220MHz, but it's getting unstable. I also found out that in 3Dmark11, the laptop eats so much power that it started running on both AC adapter and battery . Quote Link to comment Share on other sites More sharing options...
kazekai Posted May 7, 2013 Share Posted May 7, 2013 Nice, can you try Firestrike? I got 3100 with +135MHz offset. I'll try it later with higher overclocks. Quote Link to comment Share on other sites More sharing options...
kh90123 Posted May 7, 2013 Share Posted May 7, 2013 ^ I will do that later when I get the time. Meanwhile I re-ran the 3Dmark11 because I saw one artifact at the last combined test. I dropped the VRAM by 125MHz and increase the core by 5MHz. The score is about the same, I lost 2 points there.

kazekai Posted May 7, 2013 Share Posted May 7, 2013 Are you using Lenovo's Nvidia driver? I'm still waiting for official Nvidia drivers.. since Lenovo's driver can't run some games for me. Quote Link to comment Share on other sites More sharing options...
arjun Posted May 7, 2013 Share Posted May 7, 2013 sorry noob question.... does flashing with 2.02 leaked bios in anyway affect the windows 8 inbuilt key and licensing ?? thank you in advance .. Quote Link to comment Share on other sites More sharing options...

kazekai Posted May 7, 2013 Share Posted May 7, 2013 How to run Firestrike on the free edition of 3Dmark11?You need the newest 3DMark, which is different from 3Dmark11. It will run three tests (Ice Storm, Cloud Gate, and Firestrike). Quote Link to comment Share on other sites More sharing options...
NotListed Posted May 7, 2013 Share Posted May 7, 2013 This should solve the 750m issues, report back.I've just downloaded for my Y400 with GT750m and ran through all the steps from the original post but I am still not able to move beyond +135mhz on the built in GT750m Quote Link to comment Share on other sites More sharing options...
anauta Posted May 7, 2013 Share Posted May 7, 2013 Hi,I just received my SLI GT750M Y500 machine.It seems to run fine although the CPU throttles down when the video cards are used heavily.Anything to be done about that? Quote Link to comment Share on other sites More sharing options...

anauta Posted May 7, 2013 Share Posted May 7, 2013 Hi,Will be using my SLI GT750M machine at home, work and for travel.Will I need 3 170W power adapters? Or will 120W be fine as long as I do not use the video cards extensively (I will not do gaming, just image processing stuff). Quote Link to comment Share on other sites More sharing options...

But be careful because it will most likely overheat your CPU dangerously close to thermal shutdown if everything is working hard. The cooling system in this machine isn't designed to handle the heat of simultaneous 100% CPU and GPU load that's why that throttling mechanism is originally in place.Hi,Will be using my SLI GT750M machine at home, work and for travel.Will I need 3 170W power adapters? Or will 120W be fine as long as I do not use the video cards extensively (I will not do gaming, just image processing stuff).120 W is fine but it will charge the SLI system slower.

That thing must have been cooking! Temps on my GPU is slightly lower than yours, since I have redone the thermal paste. On the other hand, temp on the CPU reach 100C sometimes. I didn't get a good bin. I will prob change it to a 3840QM. Next week I will be modding an extra heatpipe for the CPU in there. Quote Link to comment Share on other sites More sharing options...
kh90123 Posted May 8, 2013 Share Posted May 8, 2013 I got 2900++ with Firestrike, but that wasn't optimum. Somehow the GPU wasn't boosting to max clock, probably due to heat issues. The CPU is dumping too much heat.Meanwhile I re-ran Uningine and 3DMark11, and broke my record again. This time I set the Long Duration Power Limit to only 36W in the BIOS. I have a +220 MHz clock offset and +425MHz memory clock offset.NVIDIA GeForce GT 750M video card benchmark result - Intel Core i7-3630QM Processor,LENOVO INVALID score: P5396 3DMarks Quote Link to comment Share on other sites More sharing options...
