Is there a w870cu BIOS that has 5870 support and can disable hyperthreading?

I've been reading some of the BIOS posts, but if anything I'm just getting more confused.

 

There is a version of the W870CU bios that allows the user to enable/disable hyper-threading and VT. It is referred to as the mySN 1.00.12GH Bios for XMG7.c (mySN's name for the W870CU). mySN is a major European Clevo retailer or reseller, which from time to time has provided laptops with an unlocked bios in limited quantities. This bios was purported to be an unlocked version, but turned out to be a mostly stock Clevo 1.00.12 bios except that it did include the HT and VT options in the Advanced Options or Chipset Control section of the bios. Several of us flashed our computers with the mySN bios and it worked fine. I flashed back to the Sager version when I discovered the broader overclocking options were not available. If you wanted to explore the matter further, a copy of the mySN bios (and supporting files) can be found at UPShare.me.

Flashing or attempting to flash your system bios can cause damage or bricking of your computer. This is particularly true when flashing with a bios from any source other than your direct reseller. Flashing a computer with the bios files referred to above is done at the sole risk of the user, and the poster shall have no responsibility or liabililty for any damages or adverse outcomes as may occur.

 

Haha nice disclaimer there ...

Most of the time Bios flashes are perfectly safe its those one or 2 where things go bad ...

I never had any issues flashing my W8760CU though... Just follow all the directions carefully even though its only a couple button presses if that ..

 

LOL. I've only had trouble once, and it wasn't serious, but was a pain in the ()to get straightened out. Still, you do hear stories, and you never know how much experience the guy that tries it may have.

 

Ya, I bricked a Toshiba using winflash instead of DOS. That's an obvious mistake.

I read through your older thread about the flash, and I thought you said that all the options were grayed out or didn't work. You're saying the hyperthreading and VT options worked, there was just no overclocking?

 

It’s been a while, but that’s how I remember it. I wasn’t looking for the HT or VT options and didn’t use or experiment with them. I wanted the option to adjust/increase multipliers, Bclk, voltages, etc. When those weren’t available, I lost interest and flashed back first to a Clevo and then to the Sager bios I had started with. What are the practical benefits of disabling hyperthreading? Heck, I might try it again.

 

The only difference between the standard 1.00.12 BIOS and the mySN's 1.00.12 BIOS are the bullions for HT, VT, and the TB overclock have been set to true. Other than that, and the splash screen, they are identical. The keyboard firmwares are also untouched. What people are really after is the "custom" overclocking options also teased by mySN before. However, these options still revolve strongly around TB so it's still no way the same as overclocking conventionally on a desktop.

And just for the record, this BIOS, though old now since it's leak for download in late May, was not recompiled by mySN in-house. The answer lies outside of NBR.

Before I continue, the HT now in the i7 era has been revamped compared to the HT from back in the P4 days. HT tricks the OS into thinking there are two physical cores instead of one. The OS's thread ordering will try to cram two threads through a core. In less than nearline/full core load conditions, it would help a bit as not all the core's resources are being used. However, under a full workload, the overhead needed for HT to even just exist will chip away at performance. The downside is legacy applications hate HT. The not-so-downside, modern applications, other than Windows Seven, aren't coded to take advantage of HT, especially games, and most especially my console emulators. Many of the pro overclockers around the world disable HT as it hinders their max overclock slightly. It is better to disable HT and reinstate the additional overclocking leeway as raw horsepower will always be faster and doesn't induce unnecessary latency, overhead, heat, and power consumption. To me, the only practical benefit is that software rendering performance would be improved. However, this is completely null since every W870CU has a GTX 280/GTX 285M or an MR 5870. Let me put it this way, if you're fine with four cores, don't enable HT. If you need more than four cores, enable HT or wait for mobile hexa-core CPU's.

 

God bless you Soviet, you know everything. Thanks for the lesson. +Rep, as usual.

 

I'm still rolling on my original 1.00.12 BIOS. I have no plans on flashing this onto my notebook simply because the i7 does everything I tell it to do sans tuck me into bed every night, and partly because I'm a lazy bum. My butt is still waiting for that single platter 250GB Momentus XT 7200.1 that is supposed to ship out to me fairly soon. But that's taking a backseat in my head for now as a very soon to launch evolutionary product in one of my other hobbies, that I'm going to revolutionize and mod the hell out of, has me on my knees praying that the calendar will go by faster.

 

This is exactly what I'm thinking. Plus, there's the less important issue of trying to track 8 cores with multimeter. I might go through with this.

You haven't written down the PLL code anywhere by chance, have you? That would be awesome.
