Additional functions in this BIOS

I decided to flash the MySn BIOS .12 for the w870cu to see if there was a difference, and there certainly is. Here are some screen pics:


Here in the advanced tab, it can be clearly seen where it says "Advanced Chipset Control"


Now within that sub-menu there lies the extra options (why this wasn't in the regular BIOS 12 release i have no idea)


Now navigating to to last option, CPU overclock, the sub-menu is displayed...

This is where my question lies, the options available in the CPU overclock menu are just 1x, 2x, 3x, and 4x. I have no idea what this could possibly be in reference to, its very nondescript, so i was wondering if anyone can help me out with this.

Here is the BIOS in case anyone wants to try.

 

That increases your multipliers on the extremes by the designated amount. 1x is designed to move the 920 from 24-23-17-17 to 25-24-18-18, etc., power and temperature permitting.

 

Hmmm...gonna have to pass on this. Not worth bricking my laptop over. Would like to see someone else try it and post their results.

 

I have it running just fine, just haven't tried that cpu overclock feature.

 

You know I took a chance and flashed my W860CU with this bios. Works fine, finally got HT disabled haha. I even have the OC options (tested with my friend's 920XM).

 

Yea its actually a good BIOS if you want a little more control.

 

The CPU overclock feature works just like eLeet or other programs that allow manipulation of the turbo multipliers. Provides a nice boost on programs that use 1 or 2 cores, but usually runs into power limits pretty quickly when 3 and 4 cores kick in. Still, a very nice feature.

Where did this version of the mySN bios come from?

 

Oh, I'm all over this. I'm running .13 now, I should ok to flash right? They both use the .10 EC I think.

Could you do a couple wPrimes runs with overclocking enabled/disabled?

 

Only works with the extreme processors -- 920XM (and presumably 940XM), but not the 820QM.

 

Ya, I just want it for the hyperthreading option right now, and if it really works I`ll be buying a 940 in the next couple months.

 

Sounds like a good plan. Have fun with it.

 

Another successful update here and my laptop is the W860CU, same as ChinNoobonic. Of course, I felt a lot more confident after he reported success. I wanted this Bios to give me control over Hyperthreading and I also plan on getting one of the extreme processors in the future so the overclocking option from the Bios will be nice instead of only having the software / Eleet tools.

I just disabled Hyperthreading from the Bios and can confirm that worked fine too.

Did you get a different splash screen saying ''Mysn'' after updating the Bios?

 

Yes I have the MySn BIOS splash screen, but honestly i could care less, i mean its only on screen for a couple of seconds, so its not bad. The reason i flashed to this BIOS was for the HT toggle as well as VT, it wasn't so much for the overclock, since i could just use the eleet utility.

 

I`m just curious of the actual difference between no overclock and x4. There isn`t any benchmark comparisons around really.

 

Well i will be benching soon... i just got my replacement 5870 and ssd so i gotta install some stuff, and just don't have time at the moment, but most definitely by friday.

 

Yeah I did. I don't mind it, as long as it's not that crappy old "StyleNote" splash screen .

 

One example of CPU overclocking potential -- using a 920XM at stock settings, it takes my rig about 12.63 seconds to complete the wPrime 32M bench. Overclocked (28-28-x-x, I think), but otherwise stock, it gets down to around 11 seconds before power throttling limits performance. With elevated TDP/TDC limits (75W/63A), the benchmark time is reduced to 9.4 seconds. At that point the 920XM is pulling about 72W, with CPU temps in the low 90's. The same settings result in Vantage CPU score of about 18,700 (vs. around 14,200 stock on my computer). At these levels, you are at or near the very limits of the 120W PSU's capacity. If you push it further, you risk frying the PSU, which of course I did. There is enormous untapped potential in the 920, some of which can be safely utilized via increased multipliers, whether thru bios o/c or by separate utility. When you push beyond that, it can get dangerous for your equipment, so care must be taken. (Note: wPrime results are for v2.03; using v1.55 (more common), times are reduced by 1.5 seconds at each point, i.e., stock run @11.1 seconds, with o/c to 7.5 seconds. Sorry for any confusion.)

 

Never mind, got what you said.

 

It's simple logic that each core in the 920XM will work as high as 3.20 GHz and possibly even more, so I am not surprised. However, an i7 running with all four cores at 3.20 GHz it's like an i7-960 running at full which is 130W TDP or even more. It's no mystery that this CPU is heavily underclocked and undervolted in order to fit the power consumption and TDP requirements of laptops. If it wasn't for those, it could attain much higher speeds.

 

It's magical to now have access to that enhanced performance potential, but capturing it requires more power, increased cooling and improved judgment, all of which I am now trying to acquire. LOL.

 

I wonder if those 160 watt PSU's that many purchased on these forums some time ago from Ebay will help at all.

 

I'm sure they help a great deal, but they're hard to find. SovietSunrise had a couple of Li Shin's available recently, but they were gone within hours. I ordered the 180W PSU that comes with the new 8850.

 

what are the benefits of disabling HT?

also where did the op get the bios? Is this an official bios, and is it compatible with the 5870? Also what version of EC do you need, and where do you download that. Not too sure what you guys are referring to when you say EC version...?

 

I'm here to save you guys money. Why spend $120+ on a 180W PSU when you can pick up the same thing for half the price. 180W AC Adapter Fits Alienware Area-51 m9750 0415B19180 - eBay (item 380197151571 end time Aug-11-10 12:09:15 PDT)

This is the Li Shin 180W PSU that was produced for the legacy D900T/D900K. They will work just fine with the W860CU, W870CU, M860TU, M570TU (and it's previous models), or any notebook that accepts a 18-20V input, 2.5/5.5mm plug. I have five of them sitting infront of me right now and are going for $60 a pop. I'll setup my FS thread later when I get back.

I had PM's for them within the hour that I put up my FS thread, haha. You'd be surprised by the number of people that are in need of one. Even more surprising is some of them need them for non-Clevo notebooks.

This is why HT sucks for a lot of people. Though I say this heavily, in reality the performance hit isn't that great. Even a 4% decrease due to HT is an overstatement. Compatibility though is a different story. http://forum.notebookreview.com/6420070-post7.html

I've mentioned this before, the mySN 1.00.12 BIOS is identical to the original Clevo 1.00.12 BIOS. The only thing that mySN did was edit three block values to "reveal" the options. When the 1.00.13 BIOS was released not too long ago, I thought about the post I made back in the link above. The original 1.00.12 and mySN 1.00.12 releases are the same, so I might as well just delve into homebrewing my own BIOS release based on the 1.00.13 BIOS, the unlocked 1.00.13 BIOS. The same goes for the other notebook lines; the same BIOS is used within the same line. I'll spare you the TL;DR, but it's really as simple as finding the correct Phoenix BIOS reader, a hex editor, and recompile and flash the sucker onto your notebook. The options for unlocking TB multipliers, HT, etc, are in all of the previous releases as far back as the original 1.00.01 BIOS (including the "unlocked" variant of 1.00.01) from the pilot release of the W870CU last year. It's just the options are hidden because of a simple false bullions. I am not at the liberty of disclosing or publishing a guide on the "how to" as I have spent too much of my time and effort researching into it and giving away intellectual property is no longer an option. The same reason goes for why I declined to publish my previous cooling project despite it's completion. The same also goes, for example, with K-TRON and his withdrawal of his previous (literally) big project. Though this time around for me, it's for moral reasons as well. One man can really ruin it for everyone. And you know who you are. The secondary reason is to protect you guys, the end-users, from screwing up your machines because of the super deal I just opened the doors to, the 180W PSU. The "120W" notebooks are not designed to handle that much power draw. Yes, you can push the moderately, but what users in this forum recently are seeking is to bleed their notebooks of every last drop of performance they can muster. The power components cannot handle it in the long term. And this especially goes to those with fully loaded notebooks with full brightness dazzling and charging the battery at the same time. One of the major components in question is the DC jack itself. The DC wire gauge isn't thick enough to handle that much current efficiently. The skinnier the wire, the more thermal resistance it will pose against the power input. If you run your notebook long enough in stress tests or all night gaming marathons on a tricked out and overclocked system, you will notice that it will get very hot to the touch, and in some cases with previous users, will melt the plastic. I caution you guys if you get the 180W PSU and successfully recompile your BIOS, overclock both the CPU and GPU, and install other components to your notebooks. The short term remedy is to heatsink the DC jack. This is part of the reason why I am hot on my seat on getting the W880CU backpanel so that I can further heatsink it to alleviate some of the heat. The DC-DC buck converters on the mainboard are also in for the ride of their life, so please spare your notebooks from the stress unless you brace it to handle that kind of load.

Oh, the latest 1.00.13 BIOS does not have the microcode for the GTX 480M. Even if you were to overhaul your W860CU/W870CU to physically accept the GTX 480M, and by this I mean the fitting of the heatsink, the software constraint will be there to greet you.

 

I want to know how the unlocked multi could be opened on M86. Searched before but didn´t find........

 

Even with a 160W li-shin psu I can't overclock higher than 27/26/20/20. Sure it seem more stable and the psu don't overheat at all... but did it worst getting a 180W ? I don't think so.

By the way, it seem like my heatseek don't touch the cpu correctly (well if i look at the thermal past that touch half the core) so I've put a shim on it.. but it don't help much to get a better cooling.

 

The 180W PSU is just a purchase alternative to the 160W unit since the blackmarket has been depleted dry of leftovers. It's a little bit pricier, but the 180W unit isn't as blocky as the 160W unit. It is the same as the 120W unit, except 2-3mm taller and 2-3cm wider just by eyeballing it right now.

 

So one of the main things we should take from this thread is that there is no reason to pay for a 940XM over 920XM if overclocking is available. They'll both throttle at the same place.

One thing I'd like to add in regard to total power usage: there are easy things that can be done to ease the load a touch or two. A externally powered USB hub is a good start. I'm looking more at power consumption than performance when I buy a SSD, and using a slower lower power second drive can help too. I just switched my second 7K500 to a 5K500.B, and my cpu idle temps went down a couple degrees. That's the drive that does my torrent work and antivirus mainly.

 

As far as heat I would think modding the existing back panel of the w870cu creating more vents might help, and then combine that with a laptop cooler.

 

It should also be that by flashing the W870CU bios on the W860CU you get RAID as an option if you install a second HDD.

 

Have you used Throttlestop? It's not as good as BIOS options, but it allows you to easily increase the multiplier or overvolt the extreme CPU's.

 

I can confirm that I can now see a RAID option in the Bios.

 

Link in the firts post dosen't work for me.

Hi!

One question-
I need the latest Bios for the mySN® XMG8.c! It´s the 1.00.07BR! Anyone with an mySN Account can download the Bios??I dont have an mySN Account, but this bios is the only one for the "Clevo X8100" that works correct with a 920XM and overclocking!

All other unlocked Bios dont work correct with the X8100! (Sager,.....)!


Thanks very much!

 

They tell that ''The file you have requested does not exists.''

 

Sure it does. Just tried, and it worked fine. Try again.

Use the link I gave you just above, not the one in the first post. They are different.

 

Now that throttlestop works with i7's, there's less of a need for this BIOS.

 

That's true, except that it's convenient to use the +1x setting to turn your 920 into a 940 automatically from boot. Still, sure do love Throttlestop.

 

The big thing I noticed is the individual multiplier settings. When I get my 940, I'd like to try and crank the 1 and 2 core multi's and only bump the 3 and 4 core settings a little. Something you can't do in BIOS at all.

 

Yep, that's useful for some benches (3dMark06 or earlier) and many games, but the higher settings for 3-4 cores will just be ignored in a 1-2 core applications, so there's no real disadvantage that I have discovered. Be interested if I'm missing something.

 

Just that when you do use 4 core apps, power draw won't go through the roof. Plus, turbo is dynamic, so if something runs in the background while you're gaming it could cause a higher power spike when switching to 4 overclocked cores.

 

That's fair enough.

 

You can get the 8850's 180watt power supply from Sager for $75.

Hate to ask ya again, but could you throw that bios back up Revelator? I only found .13 which has the RAID but no Advanced Chipset Control and I'm looking to put my XM 940 through its paces. You updated the EC/KBC to the w870's as well I assume?

Also... By cooling you mean, something like this?



Still a work in progress, but centrifugal fans are the key to overcoming static pressure (which is why the stock fans are that type...)

 

You can get the bios here. It is the original w870 bios but has the w860 EC.

Edit: Nice mods. Post your results when done .

 

Thanks! You are an officer and a gentleman. +rep.

The mods were a fun project. But the process has slowed down now that class has started. Eventually I'll put together a more comprehensive post of everything.

EDIT: WHOO HO! 3.73 GHz according to intel's turbo boost gadget.... An extra 700 mhz over the i7 820 should come in handy. Thanks again.

 

No problem. You can get a bit more control of overclocking using ThrottleStop (by unclewebb). You can find the link on the 1st page of the w860 owner's lounge or by searching the forum. It's a wonderful software for extreme processors. Allows you to unlock the 940xm's full potential .

Again looking forward to your post about the mods .

 

Will this work on my Sager NP8690 ? I wanted to get some overclocking ability for my laptop with Core i7 740 CPU

Thanks

 

works on Q9000 ?

 

Intel only unlocks the multipliers on their "extreme" mobile chips, and only then by 4 bins extra. You would need either an i7 920XM or 940XM to do it.
