14" Dell Latitude E6430 - Performance Upgrades and System Mods

Recommended Posts

Hi guys. I want to report that I managed to enable both the internal and external display inside my e6430. I used one efi var to force default gpu to iGPU, the other to set it to enabled permanenty. When it boots into windows, the radeon is recognized and begins to drive the external display. Thank you again @timohour for the save. So long as the setting is gen1, there seem to be not many issues (firefox doesn't like being moved to internal screen for example, but I'll experiment to see what works and what doesn't. Chrome doesn't mind, for example).

Oh the beauty of a good ol' fashion 1920x1200 24" display with good color reproduction, I'd forgotten thee.

Also, the CPU is MUCH cooler when using an eGPU (not to mention cooling pad), so I can look into increasing power limits and multipliers. Once the multipliers are increased through efi vars, is it necessary to do anything extra or just ramp up the multis in throttlestop?

How to keep iGPU enabled after booting with eGPU connected (Optimus Compression)

UPDATE: Check next post for variables.

Hi guys. I want to report that I managed to enable both the internal and external display inside my e6430. I used one efi var to force default gpu to iGPU, the other to set it to enabled permanenty. When it boots into windows, the radeon is recognized and begins to drive the external display. Thank you again @timohour for the save. So long as the setting is gen1, there seem to be not many issues (firefox doesn't like being moved to internal screen for example, but I'll experiment to see what works and what doesn't.

Oh the beauty of a good ol' fashion 1920x1200 24" display with good color reproduction, I'd forgotten thee.

That's great news for the E6430 community!!! This means that with the correct settings we can have both enabled iGPU and eGPU after a cold boot, no need for hot plug. This is also good news for Nvidia users since they will be able to have their card connected before boot and still enjoy Optimus compression (since iGPU is still enabled)... Also no need for manual setting of the TOLUD! Auto will work just fine.

Could you pls elaborate exactly which vars you used to make this happen for other user reference? Are those from this post?

What do you mean Firefox doesn't like being moved to internal screen. What is the issue? What if you set the internal screen as the main display? Still having problem?

Thanks for your efforts...

BTW 24" 1920x1200 16:10 rocks!!!

Also, the CPU is MUCH cooler when using an eGPU (not to mention cooling pad), so I can look into increasing power limits and multipliers. Once the multipliers are increased through efi vars, is it necessary to do anything extra or just ramp up the multis in throttlestop?

No further change is necessary. It will automatically ramp up to the highest multi... Keep the bottom lid off, it will help a lot with the cooling. You will find out that you don't need to have the bottom screws in. The bottom lid stands there by itself... That's how I move it back and forth to my work every day for almost a year now...

Yes, the vars in the link. I set them as you suggested, var 0x1D4 set to 0x0 and var 0x1D8 set to 0x1. Oh, I noticed I can also boot to the efi setting utility by copying the EFI folder to my recovery partition. No more USB stick required.

Setting: Primary Display, Variable: 0x1D4

Option: Auto, Value: 0x3

Option: IGFX, Value: 0x0

Option: PEG, Value: 0x1

Option: PCI Bus, Value: 0x2

Setting: Internal Graphics, Variable: 0x1D8

Option: Auto, Value: 0x2

Option: Disabled, Value: 0x0

Option: Enabled, Value: 0x1

When setting Internal Graphics to Enabled without setting them as default, the system boots but gives Code43 on the Intel HD Graphics driver. Once set to IGFX default, everything is peaches.

Wow, 3.9GHz across 4 cores appears to be stable but gets hot FAST. After 5 seconds of TSBench 8thread 1024 i get immediate throttle down to 3.5GHz... which is still pretty nice, considering the limitations.

EDIT: With CPU OC'd to around 3.9-4GHz average and GPU OC to 1200 from 1050MHz core, these are the new scores:

P6813 3dmark11

4684 3dmark FS

The overclocked r9-270x scores 2512 points in Furmark FHD benchmark, about 70 points below a stock 7970. Considering it's based on a 7870 Pitcairn, that's quite a bit better than expected. This is on a Gen1 link.

I'm drooling thinking of a GTX-970 + PE4C v3.0 combo, but considering how broke I am, and that this whole entire setup including the monitor cost me around 600$... I don't think I'm allowed to complain.

I think it'll be a LONG time till a TB solution can be had at similar performance / specs for similar cash.

That's pretty nice... Maybe you should consider some of the cooling mods done on the HP 2570p...
heatsink mods: by Tech Inferno Fan's (copper-stack), Aikimox, bjorm & jacobsson's 'Anarchist' - improve heat transfer to reduce fan activity or host a 45W i7-quad comfortably bjorm's holey bottom cover mod - improve airflow
All of them showed quite an improvement in CPU Temperatures without spending too much (especially the "Anarchist" mod :))

If you get your refund you will have Gen2 link and you will have much better results... That's true... I am not expecting a total cost of a 4C TB machine + Akitio + card +PSU to be under 1000$ even used...

E6430 being x2.2 capable is maybe the only cheap 8GT/s solution so far with 4GHz+ 4C options!

Unfortunately I'm the kind of guy who'll go with 'good enough' and keep the bottom cover on (though I'll drill it and use some copper shims when I get the occasion) and use expresscard instead of the x2.2. I like having my WLAN and WWAN both available and my machine easy to pick up and pack up and hook back in.

I'm not sure what benches I should be using to compare the card to a desktop-running version. I'll go look some up.

Hello, I am trying to unlock my e6430 too, but i can not find the string 00 00 0B 0A 00 00 0D 0C 18 01 08 for some reason.What did i do wrong or what i need to do now?

I want to unlock ME forever but it seems there is no such line 00 00 0B 0A 00 00 0D 0C 18 01 08 to be corrected.I appreciate the responses in advance.

@uyuzettin, Are you using HxD? If so, make sure you change the Data Type to Hex-Values.

I also want to note that I have successfully Unlocked my Flash Descriptor and Flashed the OC ME Firmware (thank you @Khenglish). Documented the steps, as usual.

@timohour, I'm currently encountering some problems with the steps for x2.2 and FITC.

After unlocking the Flash Descriptor and flashing the hex edited bios, I opened the same editedbios.bin in FITC.

In FITC, only the Flash Image\PDR Region Folder has an red X mark.(Is this expected?)

Navigated to Flash Image\PCH Strap and edited PCIe Port Configuration 1 to 01. Then I clicked Build Image​.

What I noticed after clicking Build Image F5 is that it created:

  • Int Folder (Contains Four Files: BIOS Region, Descriptor Region, GbE Region, ME Region)
  • outimage.bin (12Mb File Size)
  • outimage(1).bin (8Mb File Size)
  • outimage(2).bin (4Mb File Size)
  • outimage.map

Is there something that I did wrong, or should there really be 3 copies of outimage.bin?

Which among the files listed is needed for the next step in x2.2?

Your system has 2 flash chips. The 2 smaller outimage files are the exact image for each chip. The biggest one is the one with them combined. Use the biggest one when flashing with FPT.

I have not seen a laptop that had a PDR region, so don't worry about it.

Switched thermal paste to Coolaboratory Liquid MetalPad.

The heat builds up much slower now. I can make it through 30% of a TSBench 8thread run before I touch 100C. Basically ran into the dissipation bottleneck. During benches like 3dmark the CPU doesn't even go over 87C. 3dmark11 physics score increased by about 400 points, though firestrike remains pretty much the same, lol.

Neither are putting 100% load on the CPU.

I'll be drilling holes for airflow when I can get a dremel. God, i wish I had two heatpipes. I'm pretty sure I could max frequency on this CPU if I did.

P6854 3dmark11

Also finally touching 4.05GHz (not touching 4.1 because of the 99.7 BCLK I think).

These EFI variables can be very useful, and I'm thinking of adding this to the guide. Care to explain in a little more detail how to boot to EFI Setting Utility without a USB?

When setting Internal Graphics to Enabled without setting them as default, the system boots but gives Code43 on the Intel HD Graphics driver. Once set to IGFX default, everything is peaches.

Noted.

@uyuzettin, Are you using HxD? If so, make sure you change the Data Type to Hex-Values.

yes I did use HxD and I tried all data types including Hex values.No luck.

Then I flashed Khenglish's 6430oc.bin and installed xtu but now I am still not unlocked.

Later I used HxD and open 6430oc and located 00 00 FF FF 00 00 FF FF 18 01 08, went back to see what i have in my untouched original and it was almost the same,

i mean instead of string

00 00 0B 0A 00 00 0D 0C 18 01 08,

I had

00 00 FF FF 00 00 FF FF 18 01 FF

I changed FF to 08 and saved it as editimage.bin

I my question is; should i revert back to original image.bin and continue from scratch or how should I proceed?

I still have no manual tuning on xtu after reinstalling.

I have a recovery partition left over from my HP 2570p installation. I think it's formatted to FAT32, and thus it's selectable in BIOS when setting to UEFI mode, and allows us to define an EFI boot device on it if we copy the EFI folder to the partition. Once it's added, even though the system is booted in Legacy mode, when pushing F12, we'll have the option to boot it.

TL;DR: FAT32 partition with EFI folder and the files inside can be booted.

EDIT: now that I think about it, I can put all sorts of goodies in that partition. Now why didn't I think about that before...

I did use Clover in my 2570P to dual boot OSX. Looks like we can try to explore dual booting OSX for the E6430 too.

If your original BIOS has 00 00 FF FF 00 00 FF FF 18 01 FF this means that someone before you unlocked it... Original BIOS from Dell would have locked every region of the BIOS (and make it unlockable through BIOS options for their update process).

The last value FF means that the guy who unlocked it also unlocked the GbE region. We find no use and that's why we left it with the original value... There will be no issues with this region write-enabled unless you flash it with different values.

If you have flashed the 6430oc.bin your ME FW should be unlocked.... Try reinstalling different/older versions of XTU... When it prompts for restart, shutdown and then start again...

Also finally touching 4.05GHz (not touching 4.1 because of the 99.7 BCLK I think).

Just want to know to compare with mine what's your highest Voltage @ highest multipliers? If you have time test with Throttlestop as shown here link at the end of the post, to check how efficient your chip is.Thanks.

You can see here that my 3720QM goes up to 1.2109V and it is much more efficient than my 3630QM.

I did use Clover in my 2570P to dual boot OSX. Looks like we can try to explore dual booting OSX for the E6430 too.

This will be a very interesting endeavour... I was about to try that myself but I didn't have an empty spare drive and enough time.. Will be happy to assist.

Some pretty interesting conclusions to be drawn from this, in my opinion. Comparing to the other results posted in the link you shared, It suggest that there's quite a wide range of voltage sweet spots for low-multi scenarios. Notice how the voltage increase wildly up to around x37, in steps of 0.02-0.03V, only for that range to lower dramatically after x37. It suggests to me that the Ivy Bridge CPU's are either: 1 - massively overvolted compared to their needs; or 2: Designed to operate around 4-4.5GHz at high-voltage, 1.2V+ operation at 55W+ TDP. The fact that the heat, even at high multis, scales linearly with voltage, makes me wish I could undervolt. If I could bring TDP under 44W, I wouldn't need cooling mods at all anymore to max it out indefinitely.
Definitely anyone wishing for best-bang-for-buck performance at the moment should probably get an Ivy Bridge CPU capable of multis above x39 and in a machine capable of powering and cooling it. 3740QM/3820QM/3840QM/39x0XM.
This just makes me yearn for better cooling and an extreme chip, to be honest, but honestly, I don't think I have any good reason to complain.

Also, Banggood refunded my payment for the EXP GDC Beast. Considering the DA-2 cost me 15$, the adapter was 'free', the 24" monitor cost me 76$ under warranty (unfortunately it's not the IPS panel, but the viewing angles are so good I couldn't tell at first - it has amazing specs though) and the GPU was also 'free' (from a friend), the CPU cost me 126$, well... definitely no reason to complain.

Any idea what the following EFI vars relate to? I see them placed between PEG3 variable options, I guess it's too much to hope that we might be able to control the voltage steps for the CPU but... what if?

That's fair enough.

Are you sure that the top bin values are valid? It seems like till x35 is has lower TDP than mine and then after x36 it takes bigger steps than mine ending at higher TDP... If this is true that possibly means that for some reason the newer chips (3740QM/3840QM) may have higher TDP on top 4 unlocked bins than the older 3720QM/3820QM series...

will rerun my TDP data to confirm but we need more data for this one.

The TDP on the top bins is relatively steady so long as the CPU doesn't get over 85C. After 85C (and especially after 90) the TDP fluctuates going up, which is why I'm speculating the chip is more efficient and stable when cool (or the TDP calculation algo runs better). I did my best to get the reading before the CPU heated up but after it settled on a stable value at that multi, so they're as valid as I can make them.

Oh, so in theory those vars would control voltage for the dGPU if I had it?

Leakage scales exponentially with temperature. An LN2 user did a test on Ivy Bridge and found leakage to be nonexistent below -60C, meanwhile at high temps power draw was almost doubled due to leakage.

As for performance, FETs don't behave much differently with changes in temperature as long as you're above liquid nitrogen temps, but interconnect resistance scales linearly. This is the main reason why chips under LN2 can clock higher.

GPU voltage isn't in the NVRAM. Maybe someone very familiar with fermi era vBIOS could raise the voltage in a hex editor, but outside that I think only a hardmod would work.

Thanks for the detailed answer Khenglish. So basically, we'll start seeing a whole new era of computing when sub-zero cooling becomes mainstream.

If gpu voltage control isn't in nvram, then... What might that variable control? Any ideas?

If it were voltage to PEG devices, i'd expect finding a var for each PEG, not just the one, and more importantly, the ability to control voltage stepping gets me suspicious. I can't think of any devices outside of cpu and gpu cores that would need granularity of voltage control.

@Khenglish

Would it be possible to connect the DIV3 clock with the DIV2 clock to OC the PCIe 2.0 ports (EC, mpcie) too?

Or any other way to set the DIV3 clock to a specified value (e.g.105MHz)? It would be fun to see what performance impact such an increase would have.

I think you had implied that something like this is possible with NVRAM settings? Couldn't find any clues though.

Could we change it inside the ME firmware setting a different clock range definition? Will this make the laptop unbootable if wrong value set?

I tried a lot to get the PCH to overclock. XTU would always lock out BCLK overclocks when I set it (but it would allow underclocking). You could set BCLK overclocks in NVRAM with the IFR thing, but if you set an unstable overclock, that's a brick unless you have a programmer.

I assume you did change the clock range in ME FW in the DIV3 settings.

Where can I set the BCLK OC in NVRAM?

Suppress If:
Variable 0x3DE equals 0x0
Ref: DIV-1S, Variable: 0xFFFF
Ref: DIV-2S, Variable: 0xFFFF
Ref: DIV3, Variable: 0xFFFF
Ref: DIV4, Variable: 0xFFFF
Ref: DIV-1NS, Variable: 0xFFFF
Ref: DIV-2NS, Variable: 0xFFFF

That's the closest I could find but this is also Text for BIOS readings , not Setting.. What am I doing wrong?
