LSlowmotion Posted December 22, 2013 Share Posted December 22, 2013 tested and work on Xenom PX15 (Clevo P157SM) however, I was unable to set the ref clock, mem clock ratio, and gear ratio (it won't boot and recover the default settings). I wonder why Link to comment Share on other sites More sharing options...
Guest Posted December 22, 2013 Share Posted December 22, 2013 BCLK (Reference Clock) can only be altered in very small steps. 100-105...Mhz Better set things like memory in BIOS, XTU is not doing a good job. Set the values, then save and exit. After the next full shutdown changes take effect. (As long as your CPU, motherboard & Memory can handle the selected clocks, if it can't take them then they reset to default). HERE is a good read to understand the architecture. Mind that some features are only available for certain CPU/Motherboard models. [MENTION=17078]I'm Poor[/MENTION] PM, glad you got it working.

ajnindlo Posted December 22, 2013 Share Posted December 22, 2013 How did I'm Poor get it working? So now the fans don't run all the time?For the P1xSM bios/ec, any info on how the fan profiles where changed, i.e. before and after values? Link to comment Share on other sites More sharing options...

So now the fans don't run all the time?For the P1xSM bios/ec, any info on how the fan profiles where changed, i.e. before and after values?I sent him an EC which is more silent but runs hotter, so no good for OC. No idea about values I simply don't touch the EC anymore since the EC in the 2013 models is no longer hosted on a separate flash chip, so a brick means new motherboard.

menko2 Posted December 23, 2013 Share Posted December 23, 2013 Installed the last Bios for p170em and runs great.The only thing is that i cant restart the laptop. It shuts down... like turning off.Maybe i have to look into settings.Thank you Prema!! Link to comment Share on other sites More sharing options...
I'm Poor Posted December 23, 2013 Share Posted December 23, 2013 For me, the CPU fan was on permanently no matter what and wouldn't spin down with the modded EC and BIOS. Prema sent me a non-OC version of the EC that ran quieter. I flashed that and then I flashed back to the modded EC that came with the modded BIOS and it's quieter now and will spin down when the temps are low.

wolfik Posted December 24, 2013 Share Posted December 24, 2013 At first I am sorry, but this post is going o to be an exact copy of my post from notebookreview.com. I hope you willl understand my need Hi, Prema. Very good job with bios mods, I really appreciate your work. But there is something I need to ask you. Is there any chance that there will be BIOS that will enable CPU fan speed control? Or maybe you now what driver is responsible for the fan's good work? My CPU fan sometimes starts working at 75 degrees or even later (sometimes it's just too late) and my W350ETQ just shuts down. Of course I can force the fan to operate with full speed (FN+1) but I shouldn't be responsible for my laptop's cooling. I hope you will find time for an answer PS. I forgot to mention that I have already flashed Your up-to-date BIOS for w350ETQ. Maybe I'm just asking stupid questions but this heat management is making me crazy.

bauto601 Posted December 25, 2013 Share Posted December 25, 2013 I see that the P157SM bios mod is released! That's some good news. I'm going to buy a P157SM next week so the first thing i'm going to do is flashing your bios in it. But i read that there's a problem with the ec so the fans stay on and that someone here fixed it to first flash the Modded bios, then a modded EC and then again the EC from the modded bios. But i don't have the modded EC, so can i flash your modded bios/ec, then the stock EC and then again your modded EC? BTW, i don't have any money atm (all my money is for the laptop) but if i have money again i will donate some of it because modding a bios takes a long time and much work so i think you deserve it (sorry for my bad English, i'm 14 and speak Dutch but i'm learning it at school!)

Spoderman Posted December 26, 2013 Share Posted December 26, 2013 Hi Prema! Thanks for your awesome Bios!I can't seem to overclock the memory clocks at all..i have no option for that! Do my rams unsupport that?I was able to reduce the cas latencys, but there are no memory clock options. All i see is a Memory Clock frequency, blocked to 2 options (1.00 and 1.33) and a Memory Frequency ( at 12, can't change that, bios always refuses to boot if i do).Any advice?Thanks, happy holidays!

Stranger things happen... Thank you, so it's not a (big) problem to fix if it happens. I read on the internet that the baseclock of haswell goes in jumps so you can choose for 100mhz, 125mhz, 166mhz and 250mhz and that you can only increase or decrease the baseclock with 3mhz from those speeds. (am i explaining it good enough? I'm having a link to a webpage that's explaining it better: Haswell overclocked: the Core i7-4770K at 4.7GHz - The Tech Report - Page 1 ) Can you do this also with the mobile cpu's/chipsets or is it just for desktop cpu's/chipsets?

Is there any option to modify EC firmware to make it more responsive? Fan is disabled when CPU is very cool but activates itself when temps are above 70 degrees.

I mostly tried it to solve the awful fan profile that the P157SM has. But after flashing the BIOS (starting with "Stock" Bios 31 and EC 31) the fan behaviour has changed from the annoying pulsing in Quiet mode (every 2-3min the fan goes to medium for 30s, processor only reaches 55deg C maximum) to constant low mode. I do not know which one is the worst but the optimal would be totally quiet until the CPU is 65deg C or hotter (never happens in quiet mode) and then an rather agressive acceleration to full if temperature goes higher.Usage scenarious (two different):1. Quiet surfing on the web. Processor at minimum (800Mhz) and passive cooling activated. Using iGpu.2. Gaming FPS game. Processor att maximum performance (without overclocking thou). Using dGpu. Fan speed near or at maximum for better boost performanace and dGpu boost.I usually have Quiet mode (or rather an adapted "Power Saver" mode in Windows 8.1) for scenario 1.For gaming I have High Performance (also adapted) in scenario 2.For most convienient use I would really like to always stay att High Performance mode in Windows but if changing mode helps so be it.Is there anything that can be done in BIOS or the EC to help my problem?

You can set a slightly lower 1800mhz instead of the 1866 that you tried by changing the memory clock multiplier from 1.33 to 1, and the multiplier from 14 to 18. 1.00 * 18 * 100 (the base clock) = 1800mhz. Just something to try. Also I think 28 tRAS is too tight for 12-12-12. Try something like 32 with it. Link to comment Share on other sites More sharing options...

Well that's exactly the memory setting. 133 x 12 = 1600Mhz You tried 1866Mhz (133x14) and it failed, so the RAM, CPU or system may not take the OC too well. Few pages back the same setting worked on the same system with other hardware configuration...you could try 100x18 to run it 1:1. Also avoid XTU as it doesn't work too well for P-SM Memory OC. Change it in BIOS, then save and exit and do a full shutdown from Windows. On next boot it will use them. Hi! Are there any mods for Clevo P370SM?

What we all wish for is not possible. If the fan doesn't spin the CPU will heat up to trigger almost any value. So at that point the fan will blow and switch off once cool again and create the canyoning fan ON - OFF - ON - OFF burst. The other solution is to keep at spinning at very low speed to keep it from heating up, this is what it does now. Keep in mind that Clevos Control Center Software also influences the fan behavior. So using Entertainment or quiet mode will create a minimum noise scenario for low usage situations. Link to comment Share on other sites More sharing options...
Spoderman Posted December 26, 2013 Share Posted December 26, 2013 I get it now, damn i'm dumb. So, it turns out my ram sticks really don't enjoy higher frequencies... I've tried 1.00 and 16, it boots up ofc, at 1600mhz. With the latencies stock, i've tried 1.00 and 18, doesn't boot up at 1800Mhz :/ I've changed the latencies to 12-12-12-32, 1.00 and 18, still doesn't boot.. damn it's hopeless...i'll just stick with 1600Mhz @ 10-10-10-26, which is an improvement vs stock Maybe 2T can smooth things up a little? I made up the 1800mhz with the lower latencies, but i don't know how much better is 1T 1600mhz vs 2T 1866mhz... Well, thanks everybody! Guess i'll stick with these, and maybe change rams in a couple months just to satisfy myself Link to comment Share on other sites More sharing options...
Guest Posted December 26, 2013 Share Posted December 26, 2013 1T/2T option is in main page "setup" menu (called nmode: 1N,2N). It may very much help in getting 18xxMhz RAM up and running. Link to comment Share on other sites More sharing options...
bauto601 Posted December 26, 2013 Share Posted December 26, 2013 @Prema,I downloaded that PDF file that you posted and went to page 21 where they are talking about the bclk options. And in the mobile column they say that the mobile platform also has those bclk multipliers. Would this mean that you can (in combination with your modded bios so you can increase the tdp) overclock a I7-4700MQ 25% further? That would be great!EDIT: Didn't read good, it's xm only... (it's not xm only, see edit2)EDIT2:Holy F*** I was searching thorough the document and i found also a very usable page with a list of processors (page 24) that says if they have those bclk settings or not, and the i7 4700mq *DOES* support those bclk settings and finetuning! But only with the HM87 chipset, which is not a problem because the P157SM has the HM87 chipset so when i have my laptop i will try the 125mhz baseclock and post my results here.
