alienware 18 CPU 4930mx upgrade gives 7 beeps !!!

i just received a 4930mx cpu which i ordered a feed days back and i did the upgrade from 4910qm . but once i start the machine it keeps the black screen with 7 beeps! i did the installation twice with the same results.
i have the unlocked A12 bios and before i performed the upgrade i set all the values on bios to the default.
any idea what could be the issue ?
could be a bios upgrade issue ?
could be a faulty CPU ?
the motherboard is working since once i installed my old CPU all working fine.

 

Try the old cpu. If it has the same 7 beeps, the motherboard is toast.

If the old cpu works , the 4930 is toast,

 

i did

thats what i mentioned above that my old cpu works just fine but the new one doesn't . i tried 5 times and every time is the same for the 4930mx . i thought maybe there is something i'm missing.
maybe the volt or the current drew of the 4930mx is a bit higher or something like that

 

return the CPU and get your $$ money back.

 

4930mx is most likely toast if your old 4910qm works fine but to be sure remove the main battery and CMOS battery and hold power for 30-40 seconds to give it a full, righteous reset and then try the 4930mx
one more time to be sure.

Also post a good pic of the 4930mx top and especially the pins on the bottom.

 

I did CMOS reset like 5 times but still the same


I dont know if its viable in the image but I just noticed that at the bottom right of the front of the cpu there is small peace that is not there !!!

Check this out

 

Yeah, then the chip is defective and that chunk isn't supposed to be there. I'd return it asap. Was it an eBay purchase?

 

I will do that. No its from aliexpress.

Quick question though, since I'm gonna return this . Shall I go with the 4940MX SR1PP or 4940MX QDQH ? Ir shall I stick with the 4930mx. ( I'm going to overclock it to the max.)
I know that the 4930mx is more stable but is the QDQH is more stable ? And do u have any idea the difference between them since I searched alot and all I could find is that the QD is the one they sent for reviews .. is that true ?

 

from what @Papusan told me, the 4930MX overclocks way better than the 4940MX. I had the 4940MX on my previous Alienware 18 and it couldn't even do 4 GHz on all cores stable.

 

thats really good to know . the only thing that some says that the ES version is more stable then the SR1PP (which i could be wrong )
the sad thing is that i have the M18x R1 with the 2960xm and its stable as rock at 4.4GHZ !!

 

@islam yes you are right I had two ES 4940MX CPU's that could be overclocked to 4.4GHz and above (both were missing a few pins LOL). Tested in a cheap lenovo machine first with an ice pack then my two alienware 18's. However the retail 4940MX does not overclock well at all, in this case get a 4930MX...

 

ice pack loool.
but i found the ES version sold as used . so do u recommend it over the 4930MX?
i dont know if you read my first post on this thread that when i received mine and installed it on the 18 it didnt work and since the guy sold it to me swears that he test it before sending it to me . that got me scared that it could be something wrong with my laptop. just to make sure i'm not missing something . is there is any way that the 4930mx doesn't work on my alienware 18 rather then its damage? ( like the bios, motherboard locked or anything that i'm not aware of ?
NOTE: i use A12 unlocked bios and i installed A15 just for the sake of trying the latest bios (incase its a bios issue) but the CPU didnt work with both of them. my alienware 18 is 2014 model

 

The 4940MX is dead, it would post right away if it worked. The thing with laptop cpus is that they either work or they don’t. I believe the small damage on that chip may have taken out a few traces on the board inadvertently killing it.

If you can find a 4940mx es for cheap then I recommend it bare in mind you will most definitely need to use liquid metal to cool the beast above 4GHz, otherwise if the 4930MX is cheaper just go for it.

I hope that guy accepts the return, I’ve personally never had anything faulty turn up from AliExpress. Everything has always worked as intended

 

the only ES on Aliexpress i could find is about 50$ more expensive + i never used liquid metal before ( always used IC Diamond) so i guess i will stick with the 4930MX for the time being.
actually the guy accept returns and his communication is great so i sent it back and lets see.
really appreciate the info DaMafiaGamer

 

good luck! although presumably if you bought by credit card youd have protection too? atleast we have that in UK dunno about USA.

 

On aliexpress you can open a dispute but to be fair it's not as effective as ebay . It depends on the seller. I buy all of my stuff online and never had any issues with returns on ebay nore amazon.
However I'm not in USA I'm in Middle east dubai

 

Remember ES chips can go both ways Good overclocker or the opposite. Save a few bucks and in worst case get the bottom ain't nice. Not the way I want save a few peinnies.

 

I believe that was my first post ever lol, kind of highjacked the original thread at the time and people were genuinely surprised to see a 4940mx clock so high, I believe @danishblunt set the record after seeing my benchmark by like 2 or 3 points in cpu-z validator. Those were simpler times

 

And do you trust numbers from Danish? I wouldn't. I have taken him i lies before. Same also for others http://forum.notebookreview.com/threads/need-oc-help.809151/page-2#post-10605695

 

i guess sticking with the 4930mx will be the right choice then . thanks for the clarification

 

Remember when we say the 4930mx, ON AVERAGE overclocks better than the 4940mx, that just means you have a slightly higher chance of getting a 4930mx that overclocks better.

Over the years having had dozens of 4930mx and 4940mx chips pass my way, I found the 4930mx's had ~1bin higher capacity but that in the end the best overclocker was a particular 4940mx.
I never sold it and always kept it as a reference chip. It is currently in use now in an Alienware 18 being used by my girl. I toned it down to 4ghz because she doesn't like fan
noise.

Basically, you'll find out when you get it and start to tame the furnace that is Hotwell.

 

Thanks for the information
I get the idea of the probability but what is not clear to me is what u said about the higher capacity pin . Did u mean that 4940mx u got had an extra pin in the 2 missing pins location? ( attached a pic )

 

#I found the 4930mx's had ~1bin higher capacity#

Bin not pin ~1 bin = +100MHz higher clock speed.

 

OH , loool

 

so today i finally received my replacement for the damaged CPU and installed it.
all working fine so far . and the next step for me now is to overclock it.
i read a lot of threads about that here and all of it was done with intel Extreme tuning utility . so i was wondering, anyone attempt to overclock this processor with only the bios ?
i have a good knowledge in how to do it overclocking on the bios but my experience is from the 2960xm which was fairly easy
any feedback ?

 

so after spending 12 hours reading the overclocking thread by MR.FOX THE whole 80 pages of it and apply every single setting to my cpu, from this:-
http://forum.notebookreview.com/thr...-it-run-full-stock-turbo-speed.734696/page-78
and
thanks to @Raidriar and Pythonic for the A12 unlocked bios
i came up to a few conclusions
1- haswell CPUs runs hotter then most
2- power limits in (A) is more important then the max watts that the cpu draws.
3- downvolting the CPU helps ALOT to control the temps.
4- you don't need intel extreme tuning utility to overclock your cpu. throttle stop is much better
5- intel extreme tuning utility is SUCKS.
6- AND FINALLY SAVING THE BEST FOR LAST .. THANKS TO @Mr. Fox , @kh90123 @Raidriar @unclewebb i came with the best and most stable settings for my new 4930MX
check the attached pic tor the settings and he benchmarks
i hope this helps anyone who is looking at the 4930mx
i still thinks that it can handle 4.4Ghz so i will keep pushing it
till next time

 

Excellent job, bro! Looks like you've got it nicely tuned.

I totally agree that XTU is terrible. ThrottleStop is an excellent product, and @unclewebb is a greater blessing to all of us than what he receives credit for being.

 

Stock BIOS OC I always found 4ghz was the cap regardless.
They don’t call it HOTWELL for nothing!
XTU kinda gets the job done, but TS is just magical.
Give CB15 a run and report your score.

 

I get what u mean , my 2960xm overclock upto 4.4ghz with no liquid metal and Temps are around 95C .
I will do the CB15 today after work and will report back .. for the time being I will be using the cpu for 3dmax rendering and see the improvement in rendering time .

here is my score on CB15 with the max temp on throttlestop. but since this is my first trial so i have no idea if this score is good or bad!

 

That is exactly where it should be. Here is a screen snip of what my CB15 was with 3920XM in the M18xR2 for comparison.

 

Is this CBR-15 run done with 4.0/4.1GHz ? Can't be stock. Have you tried with High performance power plan? Aka lock it at max multiplier.

 

the third generation of the i7 was one of the best . so u think this is what this cpu can score as overclocked? i wanna try to bush it farther and see how it will react . or do u thing that is enough you got that score with what multiplier ?

this is with 4.2GHz with throttle stop . and yes its the high performance plan. . i have the setting for my overclocking by throttle stop above if u like to check them out.

ok i tried to bush it more but it cant accept 4.3GHz on all cores .. every time i set the multiplier for 43 and run the throttle stop bench, the laptop shows the blue screen
so i did 2 cores 43 and 2 cores 42 and the cash is 42 all with the same voltage which is ( 1.709) and 90W and 145A and did another CB15 run and here is the results

 

Please post pict all tabs from ThrottleStop.

I havent access to the machine for the moment. But raise voltage if you get freeze or BSOD. And stop bloat and antivirus if you run benchmarks. C0% show high values in idle.

This is 4.3GHz

 

i attached my throttle stop settings her as u asked (the ones that got me the latest score i sent before on CB15.
oh , yes i think raising the volt solved the blue screen issue , thanks
but i think i'm doing something wrong because whatever i do the watt does not exceed 88.2W. and even when i set the multiplier to 43, it still shows 4.0GHz only
here is what i suspect . in the bios i set it to the following
1- level 3 overclock
2- long power 100W
3- short power 100W
and i dont use( or even installed) the intel extreme tuning utility ( do i have to install it and raise any power limits there before i use throttle stop ?)

 

ok i finally got this CPU to 4.3Ghz stable .
the answer was there all along and has been posted by @Mr. Fox at the first post (which is the key for every thing ) please check the attached pic for the required option that MUST BE DISABLED from here:
http://forum.notebookreview.com/thr...ly-have-it-run-full-stock-turbo-speed.734696/
second thing which (since im using throttle stop ) i lowered the volt to 1.2158V which is great for lowering the temperatures of all the 4 cores to a maximum of 95C with using IC diamond thermal paste ( NOT A LIQUID METAL)
and got a great bench scope on CPU-Z and throttle stop
attached all the details for this tune.

 

so here is the great news.
i got 4.4GHz out of this crazy CPU it took ALOT of try and error but i finally got it . and here is my final overclocking settings :
1- set the multiplier at 43 for all cores on bios.
2- set the short and long power plan to 160W on bios. and thats all need to be done in bios + of course disabling the extreme edition core ratio limits as Mr. fox mentioned before.
3- follow the setting in my print screen attached . also u can see the score i have on CPU-Z and throttle stop bench.
NOTE:- i'm sing ic diamond as mentioned in my previous post , i guess with liquid metal i can bush up to 4.5GHz
sorry to send a lot of posts here , its just i like to share what ever i reached so it might help someone one day.

 

Good stuff!

At this point, you might want to give liquid metal a go to see if you can bring those temps down and/or eeeek out a little more performance.

Maybe test stability with the programs in my .sig to see where it truly lands with no throttling (power or thermal).

 

Thanks electrosoft I will definitely consider liquid metal now . Will try the software and will report back
