Heres my y510p for the sake of comparison: NVIDIA GeForce GT 755M video card benchmark result - Intel Core i7-4700MQ,LENOVO VIQY0Y1

Headcrash, please also read this thread http://forum.techinferno.com/lenovo-ibm/3402-does-anyone-know-y400-y500-ultrabay-gpu-how-connected-motherboard.html Its about similar y400/y500 . Does that answer your question ?

Well, all the timeouts this program lets you modify is in INI file in the same folder. Also you can change 90C to whatever you want - use right click menu on the icon near the clock. What you cannot modify is the stop - its not in a program, but in microchip of the laptop. Also you cannot change fan speed so to say.

You can also try http://forum.techinferno.com/lenovo-ibm/7358-ideafan-y510p.htm might be enough to start with to imagine if its worth introducing the switch and if it would help you in your case.

Yes, but mainly is there a speed difference 1600 vs 1866 - if bus between cpu and ram support it, there should be a notable difference in performance.

Varroa, are those gskill? Btw, have you tried putting 2x 16GB RAM by any chance? As so, it confirms that y510p RAM can be put and runs at 1866 in dual channel because motherboard and chip support it. The question is - does that mean that all communication channels between 4700mq CPU through dice/motherboard up to RAM itself support this and are running at this speed really? In other words, is there a way to know if bus is bottlenecking in this case or not ?

Even if motherboard would support it, 4700mq would not. As so, buying 1866 is useless with 4700mq.

Wow, nice, a lot of information to handle at once. Could you please also post pinout of the ultrabay connetor to analyze?

Id say first repaste.. I repasted twice before buying new fan for Dell laptop, just could not believe its a fan issue.. My fan was spinning for several seconds, then stopping, then spinning again, etc.. Not sure how Lenovo y510p fans act when failing really.

Fans fail. I have just replaced my fan on Dell.. Being said that, also laptop might need simple repasting.

There are some issues with the fans on y510p and at least some members on forum.lenovo.com encountered them. If fans are not spinning, might be faulty fans in the end. Also they might be faulty if you hear them spin and stop on idle, just some buzzing noise.

You can now try IdeaFan http://forum.techinferno.com/lenovo-ibm/7358-ideafan-y510p.html

With underclocking CPU/GPUs + Hyperthreading Off + cooling pad + repasted ultrabay + IdeaFan + adaptive vsync my maximum temperatures ~80C in Crysis/Crysis2 if you ask about temperatures inside. BUT, it does get hot on the outside near keyboard, but after repasting ultrabay gpu it does not get hot on the right part of the keyboard anymore.

I think something similar in y510p could be done as in y580 http://forum.techinferno.com/lenovo-ibm/2260-lenovo-y580-y480-unlocked-bios-versions-125.html#post102079

Wow, nice!! What about 3DMark Firestrike 1.1 (the latest one) score?

3, omg..

Have you been able to break 4000 score mark for 3DMark firestrike 1.2 at least?

I got 3-6C temperatures drop. So your spacers must have caused 2-4C drop more I guess. Would be interesting to see those spacers (ebay link or something).

Have you checked if its set to legacy boot or UEFI boot? Maybe thats what changed. Or what boot error do you get if you cannot boot ?

Release v1.4 is here: Please test it. This version still keeps my GPU not throttled, and it seems to be running pretty consistent on my pc.

Ok, theres a lot you can do. But first of all, please note that XTU and ThrottleStop does similar thing and running them together you might lead to unexpected results. Most notably, if you set something in XTU and then run TS, then TS might override some XTU settings. And vice versa. Also note that -70mV is good.. unless you set multipliers too low => or processor lowers voltage in some state and voltage gets to low => which leads to system crash usually because of lack of voltage. Modded BIOS might help with this - it can change for Windows to boot directly in Turbo-Performance state instead of non-turbo state which would allow lower voltages to be set and windows not to crash during boot. As for recommendations, maybe lets hear first from @Unclewebb as he is most advanced and with most knowledge, I think maybe we could put a guide together which in turn would benefit us all, how to go about the settings, step by step, for XTU, TS, which P95 version to test on, which processor usage % to set in power options, etc.

Also on what resolution does this happen? Maybe it can be OCed to 120Hz in 720p then?

Its just a wait time in a main loop until it checks if something has been changed, i.e. hotkey pressed. After a check it may enter dust loop or not.

Its hot swapable if windows boots up with it in the first place..
