  1. It seems like I am the only one that I was able to OC my 3720QM with an official Dell adapter. The reason probably is that my 3720QM @ 3.8GHz is under the default short term power limit of 56.250W But I ran my CPU [email protected] for almost 255 sec without throttling (sometimes less sometimes more). Could you test your 3740QM with your unapproved psu adapter? How much is your maximum consumption [email protected] under full load (tbench 1024M)? If it is under 56.25W it should probably work with your Dell Adapter for small windows of time (128 sec). I currently have at home a friend's E6530 and going to try my 3720QM in his laptop this weekend to check if it works like in mine or needs an unapproved adapter. He picked it up earlier today. Didn't have enough time to try my 3720QM . Maybe another time.
  2. Let us know if you find anything interesting... there is also 1080p 14" LVDS as suggested by @jacobsson on the 1st page... I couldn't find it anywhere available. EDIT: It seems that there was a typo in the panelook.com. It now states that this screen is a 1366x768p. Seems like there are no 1080p 14" screens.
  3. All info gathered on cables on this post. Part no for HD+ cable is JTC08 or CYM5C the latter seems to be the one for the E6530 but it fits the E6430 too and it is reported working here. I didn't find any notable upgrade for my screen that came original with my E6430 (900p) but there is an eBay seller who claims that an 1680x945 screen is compatible with the E6430. but it may need some modifications (check here for the successful implementation on the T430).
  4. That's strange cause this is indeed the original Dell adapter. I don't have my 90W around but compared to the 130W I got with my dock they are very much alike. If you happen to get another Dell 90W adapter, could you please test with that too? Also could you install the Dell Feature Enhancement Pack as described on the Battery Life Tweaks and set your scheme to max power and test if it throttles too? Is this limited to iGPU devices only? Doubtfull cause Khenglish (E6530 dGPU) explains here that I never encountered such an issue with my 3720QM, I just had problems after some minutes of full load. but could it be an issue on newer IB cpus (XMs and 3740QMs)??? What were your temperatures when throttled @ x34?
  5. please upload the photo if possible. Is this the adapter that came along with the laptop or just a Dell you purchased online? It sounds weird to me that 2 different PSUs failed to provide enough power unless they are fake or not official. Does the bios says 90W adapter?
  6. I am quite sure that it is either an 65W adapter (19.5V 3.34A) or a faulty one rather than a 90W . It sounds strange to me cause I never had such issues with my Dell 90W adapter. If possible pls post your BIOS version too. You can find it on the first page of your BIOS.
  7. Check that your limits are in place with throttlestop (TPL) Also check your PSU. I assume you already know that but check your bios to see which Dell PSU you have connected or check the A on your brick.
  8. Is this with the long and short duration limit set to higher values or defaults? I have been using my E6430 with i7-3720QM @ full multipliers withouth issues with both 90W and 130W Dell PSUs. Only problem was that after a few minutes of full load it will throttle from time to time as discussed here. I could test on an E6530 I recently grubbed for a friend too but I don't think it will make any difference. Most of the times the standard power brick shipped with E6430/E6530 is 65W. Could you check if your Dell PSU is 90W or 65W? Could you provide your BIOS version too?
  9. Can't say for sure. But your theory could be valid.... Do you have a desktop you can test if the card has the same results there? Also did you try to set the EC port @ Gen2 (either with setup 1.30 or UEFI variables)? Sorry for the late reply but I couldn't reply The new forum may have some things out of place but it is certainly better... I thought it would never come up.
  10. Try something that puts more load on your GT730. Furmark for example and monitor. If it shows x1.2 even for a little it is enabled and it goes down to x1.1 to save power. Does this happen on the internal screen or external? do you have an iGPU or dGPU model? Why set this 2 cores and not All? Setting this to all or better restoring the BIOS to your defaults would solve any issue. 88 C is not very high. These chips thermal throttle by themselves @ 105C. I have had turbo enabled for more than 6 months and @ full load I saw temperatures of 95C (Prime95), but in everyday work I never saw such high temperatures. You can either use Throttlestop to set profiles (Gaming / work / web) or better I installed the Dell Enhancement Pack which provides extra power options. I would use each power option when I needed it (full power, cool or extreme powersaving).
  11. What do you mean you can't enable all 4 cores.. You don't have to change anything. It will work OOB. Check into your device manager under Processors how many Intel® Core i7-3630QM CPU @ 2.4GHz do you see? If there are 8 you are OK! In order for the dynamic TOLUD to work you should set the BIOS boot mode to thorough. If this doesn't work you can always set your TOLUD manually with UEFI variables. What are your specs? iGPU/dGPU/eGPU?
  12. As a E6330 user I would like to ask you if the E6330 is much lighter to carry around compared to the E6430... Nice you find these helpful... you got some great specs and you can see at least 10% more CPU power with an OCed i7-37x0QM... There is no documentation for upgrading the screen on the first post but you can find some potentially useful info here. Too bad there is no 1080p or bigger 14" option for our laptops (1CH or 2CH LVDS)...
  13. Seems like Flexible I/O is still a feature in series 100 chipset but series 100 chipset goes from up to 8 PCIe 2.0 to 20 PCIe 3.0 ports!!! Intel® 100 Series Chipset Family PCH Datasheet, Vol. 1 pg.26 Considering that x1.3 is faster than x1.2 and almost as fast as x2.2 link an potential x2 3.0 would be almost as fast as TB2!!! It would be difficult to find adjacent ports to create the x2 link out of the 20 ports but most Broadwell/Skylake laptops come with M.2 slots for WiFi and/or Storage... It could be feasible though to use a M.2 WiFi or Storage port along with a working adapter for the eGPU either x2.3 or x4.3... TB3 is now officially supporting eGPUs but if x2.3 is easily implemented, it could be a cheaper solution for low budget Skylake laptops since any adapter will be passive (no thunderbolt chips on either sides)... UPDATE: Bplus announced a new adapter the PE4C V4.1 which can use either an M.2 M or an M.2 A/E and is supposed to be able to achieve an x4.3 connection!!! Impressive performance for an $80 adapter! We will only need a laptop with an M.2 M key empty slot.
  14. Left is the one I made for badbadbad and right is yours... Do you see the difference??? The Clock Div Min is what sets your upper limit. Khenglish set this 0x0180 which is huge. If you want you can set it 0x0A00 (~120MHz) or closer to 0x0C0E... Happy OCing!!!
  15. Regarding your ME FW OC: There is no difference if it is an i3 or a i5 or a i7. I had successfully OCed my i3-3120M @2.62 using BCLK OC. The problem is most probably that in your modified ME FW the clock range definition record has not been changed. I had made the same mistake the first time I modded and @Khenglish helped me fix it . Could you provide your ME FW dump to check?
  16. Many thanks for collecting everything on RAM and adding details. If it's okay, I linked your content on the first post for future reference.
  17. Nice to see your way through this. Regarding your memory you can adjust a custom profile. If you know your way around tweaking memory there are a bunch of variables that you could try check this post Mine runs OK @ 12-12-12-36 CR 1T You could run an AIDA test to confirm but I believe that your CL11 2T is faster than my CL12 1T. A bunch of performace results here. Could you help me with something? Could you test if your i5-3230M has any unlocked multipliers? It is confirmed that i7-37x0QM and i7-38xQM have 4 unlocked multipliers, meaning that the maximum 4C turbo for an 3720QM is x38 opposed to default x34. The maximum multiplier on your i5 is x32. Could you use the UEFI variables to set your 1-Core Ratio Limit it something a little over x32 (let's say x33) and check if it has any impact on your maximum multiplier reported with Throttlestop? It would be great if dual core i5-32x0Ms or i5-33x0Ms have some unlocked multipliers. If the same rule applies an i5-3380M would go up to 3.8GHz 2C and 4GHz 1C... Also, if you have some time. It would be helpful to investigate if we can OC the iGPU on an i5. You can check here how it worked with the i7. I tested with my i3 and it was a no go. Let's find out if it works with the i5s Although I think this would work on lower multipliers it seems that on the i7-37x0QM at least once voltage hits 1.21V it won't go higher than that. e.g. on my 3720QM x37 & x38 share the same maximum voltage 1.21V. Even if I set x37 there is no undervolt. I don't know if this is limited by the chip or the laptop. We need someone with another (gaming) laptop designed to host and OC these CPUs to confirm if the maximum voltage for non Extreme chips is 1.21V or it is just another BIOS bug on our Latitudes. But, it can be used though to raise performance... with x39 it would go up to 4.09GHz ;P
  18. You just fired my curiosity... I was under the impression that 8MB wouldn't make a big difference. Could you specify an example where an i7-3820QM would be faster than the 3740QM? (ark comparison) Cause the price difference is usually huge...
  19. Thanks for your super fast answer! A colleague envied my E6430 and I was thinking to swap to something smaller/thinner and if possible with backlit keyboard. 12,5" is too small for me at least for my needs right now. I would also like to keep it as low in price as possible. I would love something thinner ULV based but, from your exprerience, aren't those Haswell ULVs much worse than the i5-33x0M that comes with the E6330/E6430s for as low as 200$? The only compromise is the standard HD screen vs the FHD options on the 5440. E6440/E7440 is more than I intend to spend for a Haswell. Skylake is on the corner EDIT: AFAIK 6430s doesn't support 3G. The slot is there but there are no antennas due to the bigger screen.
  20. Since all H61 desktop boards supported IB cpus with microcode updates it will probably work without issues with a dGPU/eGPU. IMO though, the lack of native USB 3.0 on SB machines is worth the extra $$ for an IB machine. Q: Do we know if the i5-33x0M series have the extra turbo bins? The desktop i5-33x0 (it is 4C though) have 4 unlocked turbo bins. I am considering a lighter/smaller E6330 but it comes with non-socketed i5/i7 cpus and I was wondering if I can get a bit more out of it or it. I can't find any info online.
  21. There is actually no reason to invest on an XM chip on the E6x30 series.Even if you need the extra cache (which IMHO is not a big deal) i7 38x0QM would have the exact same amount as the XM chips. XM are better than the QMs in aspects that are useless for our small laptops. - They have fully unlocked multipliers (useless cause after 4.0GHz we face serious thermal issues) - They have unlocked voltage (useless cause there is no way to control voltage on these machines) The cons: - Their voltage can go over 1.2109V (limitation found on the 37x0QM possibly applies on 38X0QM) and this way XMs have higher voltage for higher frequencies resulting in more heat - throttling. - They are more expensive than 38x0QM and even more expensive than the the 37x0QM which seem to be the best value for money. Check the comparison here to see for yourself that there are minor differences between the two... I would recommend to save the extra $$$ for your Skylake build or a better GPU... I was about to grab an 3920XM myself but followed Tech Inferno Fan 's advice here, grabbed an i7-3720QM and have no regrets. My 3720QM runs @ 3.98GHz-4C turbo and is enough for my needs. I know that an XM chip WON'T have better performance cause throttling will kick in earlier due to thermal reasons. (Keep in mind with 300$ you could grab two 3720QM )
  22. Hello, happy to see another E6430 implementation. The reason your memory runs @ 1333MHz is your processor. SB i3-23xxM memory controller won't go over 1333MHz even if the module are clocked @ 1600MHz. Also the IB i3-31xxM won't go over 1600MHz. It is definetely not a BIOS restriction. I am running A16 and paired with a i5/i7 it goes all the way up to 2133 if your memory supports it. Check that every port of your machine works without issues (usb, e-sata, usb 3.0) etc. Check that the DVD is reading and burning successfully. Use the ePSA tests coming with your laptop and stress your memory with Memtest. If you have a dGPU run Furmark for some time and check for artifacts... It will probably pass everything without issues... If you are planning to upgrade your CPU definetely consider an Ivy Bridge Processor as R.O.G. suggested. i7-3720/3740QM and i7-3820/3840QM are the best performers... Consider them over an i7-36X0QM because on our Latitudes you can unlock the top 4 turbo bins using UEFI vars.. UPDATE 1: Seems that BPlus have possibly discontinued PE4C v2.1 (it is reported out of stock on their site for a while) and replaced it with the more stable PE4C v3 which has soldered both ends, Meaning that there is no available hardware at the moment to achieve a stable x2.2 link. There are still some remnants on eBay but it is not possible to purchase the extra PM100C cable to create the x2 link. They are all out of stock. UPDATE 2: PM100C is now again available for 20$ plus shipping. PE4C still not available.
  23. impressive!!! I have been dreaming for a while for such a setup... It can be costly though.. on the E6440 It would be fun to see a RAID0 3x250GB 850 (2 x sata & 1 x msata) touching 1,5GB/s R/W!!!
  24. The bottom lid doesn't need to be screwed to stay in position. At least in my laptop. I had been carrying my E6430 to work every day for the past 3 months. I have the bottom lid unscrewed and I took it off every morning that I attached the laptop to the docking station. Using an extra fan showed much better perfomance but I was too lazy to adjust it everyday... Having an open lid and using the additional fan to cool it down shortened my render times more than I could imagine. Offcourse using a laptop cooler along with the open lid may have helped the same but I never tried one... IMO you will be amazed by the temperature difference with open and closed lid.
  25. Nice!!! It shouldn't go up that fast though... Do you have the bottom lid closed? Cause mine @3.98GHz with Prime95 after 6 minutes of full load with open bottom lid temperature wouldn't cross 95°C... UPDATE: If this is with TSBench seems like your chip is not very good thermally. You can see here that my 3720QM @ 3.8GHz is ~ 50W @1.2109V. 59.4W is almost 10W more at the same voltage! Do you still have your dGPU disabled?
