Thank you @timohour! At least OC can be used on the spot rather than from Bios/Boot. Waiting on the PE4C v2.1, and excited to get everything up and running.

Regarding the RAM OC (via XMP Profile), is this safe/stable to perform on top of a CPU OC (Multiplier + BCLK)? Just curious cause your post did mention benchmarking RAM on a 3720 instead of a 3630 due to workload/stress.

I'll walk into OfficeDepot in a bit to see if they can order it for me. Might as well try it while I can!

Why not get a lot if you can. I'm sure there are a lot of buyers here..lol

Yeah. I did some reading and found out that the problem is just with Staples. Best Buy, Fry's, Office Depot, etc. are all delivering. Walmart just flat out denied the price matching.

Tried going to Best Buy. The problem is that they're out of stock even online.

People were buying in bundles!

Would've gotten two GTX970s, and traded them for a GTX980 Ti. lol.

Keep in mind that

* This mod is recommended for those who want to use a modified ME FW in order to BCLK OC using XTU.

* It won't help you unlock your Flash Descryptor though to set port 1 @ x2.2 (8Gbps). You need to use this mod.

NOTE¹: It has a watchhog that change it again to 0x00 after a sleep cycle or shutdown but who cares. You can mod you descriptor to be definetely unlocked and enjoy!!!!

Too bad that's just for BCLK OC since I can only flash the ME Firmware region.

NOTE²: It seems like the Descriptor region is still locked. You will most probably still need the pinmod to change the descriptor settings (x2 2.0 & permanent unlock etc) but I can flash and reflash OC_ME fw without issues.

Ok I understand that the Flash Descriptor is for Port combinations (x2.2) and requires a Pin Mod, while flashing a modified ME Firmware allows for BCLK OC c/o XTU slider.

Could you please help clarify a few things for me?

1. This UEFI variable 0x228 unlocks the ability to flash a (modified) ME firmware over the current one, right? But it undoes the command/re-locks itself after a sleep cyle/reboot.
   
2. When UEFI variable 0x228 reverts back to locked/disabled, do we get to keep the newly flashed ME and its OC settings, or do we have to re-flash ME every boot?
   
3. In the event I set the BCLK OC too high, what bad will happen and how do I troubleshoot/revert the changes?
   

Unlike the +400Mhz tweak, this BCLK OC sounds like it has a greater risk involved so forgive me for erring on the side of caution here.

I don't mind a cancellation if they are honest enough to admit that they are short on stock. BUT, if someone can order at full price and receive the item, then this act of deception is grounds for a legal battle.

Sorry to hear about that. If they are really out of stock, then they should update the webpage. And since the deal of Microcenter is still online, they should definitely price match.

EDIT: And here we go..I got a call from Staples too regarding cancellation. Can anyone confirm if buying the same item at full price will get your order cancelled? This sounds kinda fishy to me since the website still has it available.

The problem is the price difference since you have to have the invoice as proof.

that is exactly what I did and what happened lol these guys were kind of excited and more interested what I was building they thought it was cool it was going in a Z97 4790k w/ddr3 2800mhz system @Khenglish it worked for me at Staples 20+ miles from me. showed them the ad i printed of the webpage linked in the op and they were willing to proceed with getting me a comparable card for a matched price. Staples price match guarantee says for stores that have a brick and mortor store and Microcenter does and they honor online ads by those venders as well is why I chose staples to try first. cheers and thanks again BadBadBad

No problem at all. If they price match you @Khenglish, doing a Visa Check out will slash off $50 from a $200+ purchase, lowering it to $206.94. Ask if they take coupons as well so you can get it even cheaper lol!

I see you are from upstate NY. I guess you drove south several hours to NYC just for this deal? I looked and the only microcenters in NY seem to be near NYC.

You don't have to go to a Microcenter. People from Seattle have received their cards and they're the furthest state from a Microcenter.

@mw86 probably went to the closest Best Buy/Staples/Fry's and showed them the link. You guys upstate might even have the advantage because the employees there have not been badgered as much by customers and may be willing to do a price match for you.

Nice one! You should've bought some coupons too! Staples had a few $75 ones selling for $50 on Ebay.

This definitely is a deal of a lifetime. Even if you buy two GTX980s for SLI, you don't even pay the full price of one!

I went with the link on my phone to save on paper, but yes that could work.

Just look for someone willing to drop the price because apparently, they already know about the deal and can be a PITA. BOL!

What a deal wow wish one of the stores were local to me, the deal says in store pick up only. Either way very cool find

Crazy, right? You actually don't have to buy it from Microcenter itself. Any Best Buy, Staples, Fry's, etc. should offer a price match.

They drop their own prices to match Microcenter's discounted price.

(Here's an example)

And to top it off, you can actually use some of the competitor's discount vouchers (like the Staples $75 coupon for $50) to get it for less than $200!

Once again, thank you @timohour. I didn't know the 35W limit was the factor holding back the 2570P. This makes perfect sense now.

Just to be clear on instructions:

• Run Throttlestop, check max Multiplier achieved
  
• Edit UEFI variables by adding 4 bin to the max multiplier (If upgrademonkey is correct, then it's x37 -> x41 1-C, x40 2-C, x39 4-C)
  
• Reboot
  
• XTU BCLK OC (A bit of Trial and Error, but is 104.7Mhz @ x40 a good starting point. I wouldn't know how to reverse the bricking/BSOD)
  
• Reboot
  

Hope to get this OC working soon.

We will be happy to attend your successfull Latitude OC. Feel free to ask anything else you need.

Thank you so much! This was very helpful indeed..

My CPU isn't an OEM version and throttles at x33 during my Throttlestop benchmarking. Should I go for the x42 (4 bins above my CPU's theoretical max), or x37 (4 bins above my CPU's real world max)? This was done on my HP 2570p.

For any of you guys living close to a Microcenter, there is a huge deal going on right now.

www.microcenter.com/product/438838/GeForce_GTX_980_Superclocked_4GB_PCIe_Video_Card

If it's out of stock, you can ask a competitor to price match it and get it from them instead.

100% Legit, saved $379.25.

Hello @Khenglish, I hope you don't mind me asking if we have to modify all those UEFI variables in Step 2 of your [GUIDE] Dell E6530 CPU TDP/multi unlocking.

EDIT: I guess we can get away with just 0x25, 0x26, 0x27, and 0x28. Thanks!

Thank you @timohour,

I read the [GUIDE] Dell E6530 CPU TDP/multi unlocking and am trying to understand the actual steps involved.

My (Simplified) Steps in CPU TDP/Multi Unlocking:

1. Obtain the IFR file (E6430-A07_IFR.txt)
   
2. Obtain the NVRAM tool (http://brains.by/posts/bootx64.7z)
   
3. Format a USB thumb drive to FAT32 and place the bootx64.efi file in the EFI\Boot\ folder.
   
4. Boot to EFI on Startup (Pressing F12)
   
5. Load the bootx64.efi (Loads Grub)
   
6. Overclock by assigning new values to certain NVRAM addresses (using the "setup_var address value" command)
   
7. Reboot
   

Just a few questions regarding step 6 that I hope you don't mind answering..

• How would I know what the ideal core limit is? Do I assign in increments and do trial and error, or should I be watching out for something here?
  
• What is that adjusting/balancing of multiplier in relation to the BCLK OC headroom all about?
  
• Can I use the 99% CPU usage setting to prevent the overclock when not needing max performance?
  

So sorry, but I just couldn't follow how you chose 1C=40, 2C=39, 4C=38 as your stable core limits, moreso that part with BCLK OC headroom in your post.

Thanks a lot!

Thank you guys. So x4.2 is the closest we can hope for then.

How do you enable the ASPMs via UEFI variables? Planning also to migrate to Windows 10 so I might go the UEFI route too over MBR+Setup 1.30.

With the dynamic TOLUD I could see that TOLUD would go as low as 3.25GB. (at least on my Latitude). This wasn't enough to use dGPU and eGPU at the same time without compaction or connect multiple eGPUs. That was at least in my case.

Oh nice. Does this also mean that you can theoretically have eGPU SLI: x2.2 with the mPCIe slots, and x2.2 with the ODD/Sata+EC?

@badbadbad Ivy Bridge based Dell latitudes have a dynamic TOLUD, so you will not have allocation problems.

Thank you Khenglish! May I ask what good the 2Gb TOLUD tweak is for then?

As soon as I get more time I will continue this project but I would love for the E-module port to be figured out by the time I get this thing made. I have a few other projects to get done this summer with another mechanical engineering buddy so this may be a weekend only project. I already bought the connectors, no way am I giving up now

Oh hey TheClassicalCat, good to know you haven't dropped support on the project. I have limited experience with hardware, but I'd love to find a way to help out.

x4.2 is such a dream..

Regarding GTX770 working better than GTX 970, I meant the PCIe allocation of the GTX770 allowed PnP on the 2570P without modification. Sorry about the confusion.

http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge-101.html#post120247

GTX970/80 cards require a contiguous 256MB block for PCIe allocation making them no longer PNP on a 2570P. When I tested a AMD card on a 2570P I required both a DSDT override AND Setup 1.30 to get it to work.

In comparison, GTX7xx/GTX6xx cards require 128MB+32MB+16MB and so have been found to work in a PnP manner with the 2570P's default bios-allocated PCIe config space.

Consider this as well as the performance ranking below before you jump for a GTX960. GTX680/770 can be had for low $$ as secondhand ebay units.

GTX760 < GTX670 < GTX960 < GTX680 < GTX770 < GTX780 < GTX970 < GTX780Ti < GTX980

@Tech Inferno Fan, I edited the original post so you can do some mod magic. Sorry about that.

Thank you @timohour.

Referring to that "GTX770 working better" issue, I mean Plug n' Playability.

It was mentioned before that a GTX970/80 requires contiguous 256MB block for PCIe allocation. Will this cause any problem on the [email protected], or is this solved by the 2Gb TOLUD tweak?

Do I also have to solder the cable connector to the eGPU port to maximize performance and stability? Or will it stay problem-free as is?

Thank you!

Maybe better could be achieved if I replace my current SSD with an 850 EVO.

For an Ivybridge notebook, does a Samsung 850 EVO offer anything better than the 840 EVO? We don't have DEVSLP implemented, so I imagine an Samsung 840 EVO/PRO to be the better SSD to have.

Also, is the PE4C v2.1 @x2.2 (mCPIe) the best way we can maximize our eGPU at the moment? Will it handle a GTX970 better now than a GTX770? (GTX770 was working better than GTX970 @x1.2opt). Maybe Tech Inferno Fan can help sort this one out for future e6430 users.

Thank you so much for all the help and steady progress being made here.

Now I'm really excited for 2016! With all these announcements (Skylake, TB3+eGPU, 512Gb micro SDXC, etc.) would the NUC have a fighting chance at gaming?
