Latest Intel XTU allows 2 bins for G751 / i7-4710HQ

[Edweird]

Hey, guys.

So in the i7-4720HQ thread >here< Antoine supposedly came across something interesting.
All I had to do was install XTU 6.0.2.8 (which had to be done manually, since XTU itself didn't recognize the new version) and voila. 3.5 > 3.7GHz. Haven't done any benchmarks yet, but there you have it.



Previously, this wasn't possible with firmware over version 202, though I have not tested older versions of XTU for it...since, apparently, this version bypasses whatever changes ASUS might have made. Thanks, Intel?
No troubles so far with it ... an extra 100MHz is an extra 100MHz. Dunno what changed.
I imagine this would work for all G751s. Have a go I guess, not much to lose.
No problems with Watchdog, either. Running firmware ver. 207 and Win10. warryabel thinks it won't work on Win8?

My blck sometimes spikes too, it has always done that, especially on startup if I remember well.
Now, with 101.58 in XTU, I sometimes read about 103 as maximum.

Maybe it's some kind of automatic OC by Asus, I really don't care much about it, because it's rare and goes up for very short time, not in constant load.

would like to see a picture of the raised fsb...you ocing the fsb/bclk with xtu 6.0.2.8?

Yes, 6.0.2.8. Every application read the increased FSB and the resultant 3750 MhZ in 37x multipliers.
Right now multiplier go up to 35x because I'm on stress test and all 4 cores are active at moment.

Five different software: 101.3/101.35/101.4 🙂

Thanks, I'll be trying Realbench! I am not sure about hitting power limits, but Planetside 2 is a very CPU-intensive game, and if you have even a halfway decent GPU, you're most likely to be limited by CPU. That's why I want to get everything out of the CPU. 🙂 Thanks again for your advice!

I can suggest you to play with XTU running in background, and after a game session you can check the maximum wattage and if CPU entered in Power Throttling 😉

I did game with Afterburner monitor open to see if temps go too high, when I had oveclocked the GPU, but yeah, I should do that with XTU monitor as well to see the (possible) throttle and power infos.

thx andreacos i ask because intel has offerd in the description of 6.0.2.8 without bclk oc... read this tread side 6 first post! is this false?

I read that. I don't know exactly what Intel means with that statement, but it works. I noticed a little improvements in benchmark score with raised FSB, so it definitely works.

You can try yourself 🙂

@Andreasco: Hah, I just downloaded Throttlestop 8 Beta 7 today and managed to unlock +2 on all cores :)). I was just coming to say that on the thread. Okay, so now, I'm actually only running Throttlestop, as the latest 8 Beta 7 version has undervolt option too, so I don't really need Intel XTU anymore. I also like Throttlestop more cause it has the Hotkeys and I can easily change profiles for the CPU.

Now, as for the performance part, even though I managed unlocking the clocks to x37, x36, x35, x35 I still don't get your scores in Cinebench. I'm never near the 700point. And what's stranger is that I checked the Power Throttle limit and I never hit it during benchmarking. I used both Intel XTU and HWInfo64 to check this out. It might be because of my -75mv core/-75mv cache undervolt.

I actually tried lowering the undervolt to -50mv/-50mv and HWInfo64 showed that EDP (electrical design point) was reached. With -75mv/-75mv it never tells me this. Even so, I am currently running with Package Power Limits at 55W/65W just in case, but I never go above 51W during benchmarks.

And yes, I'm always running High Performance plan in windows and I made sure every option is tuned for maximum performance in the plan settings.

So actually, the only differences are the increased FSB (a +40-50Mhz), the RAM timings and the dual-channel mode.

I'm going to OC my GPU for the Realbench test and see what I'm gonna get with that.


Btw, during benchmarks, my Core 3 (4th core actually) always has lower temps. Is there any possible way that it might not work at its full potential ?

Yes, latest version of ThrottleStop is really good.
I keep using XTU just for RAM timings and FSB.

However, EDP is the current limit. Set it to 90A in XTU and you should avoid this.
-70 mV can seem stable in these not really heavy benchmark (realbench, cinebench), but in my case crash in light use like browser (LOL) and in heavier load. But we know, every CPU is different, and if you can run 37x stable at -75mV, you're fine.
As said I'using Prime95 v26.6 to check stability.

On Geekbench you have also my score with stock FSB and RAM timings 🙂
So, the only difference now is the amount of RAM (8 vs 16) and the Dual Channel mode, but I really don't know how much difference can do.

Cores different temperatures are normal, I have always up to 4-5° gap between the hottest and the coldest core.
Sometimes you can reduce this gap with a repaste, but I don't think it worths in your case, your temps are fine 🙂

One question, before it's too late. 🙂

If I run into problems, for example, laptop crashes and wont boot anymore, because of the changes done with XTU, how do I proceed to unbrick the laptop? Remove the CMOS battery to reset everything to defaults? I've been running max undervolts (achievable with XTU) in normal daily use now for about 2 work days, with no problems, but I haven't really stressed the laptop.

And a newbie question also - FSB = BCLK = Reference Clock (in XTU)? I've had an impression that changing that can lead to problems, is that correct? Or just something that needs to be tested by for example stress testing?

Here it's only noon, and it will be a looooong day of testing 🙂

Theoretically, if you do some wrong adjustaments in XTU, then Intel Watchdog Time Driver (WDT) will reload default settings. I experienced this with undervolt, reference clock, etc.
RAM timings seems a problem, if you go too low with it, WDT is not very able to restore default setting and you may brick.
It happens to me and I had to remove CMOS battery. Maybe, you can only remove a RAM stick, PC will detect hardware changes, and reload default setting. In this case you don't have to remove the entire motherboard from the chassis.

For FSB, yes it should be Reference Clock in XTU.
Increasing FSB clock, you will increase the speed of every device connected to the motherboard (CPU, RAM, GPU, hard drives, etc...). So, you have to do really little increase, because not all devices can accept this speed increment.

However, with different stress tests (CPU, RAM, Cache, GPU, hard drives) you should be sure that it's stable 🙂
