Help - RAM Being Throttled

Hi All,

I recently installed 16GB of Kingston HyperX memory into my laptop removing the old memory that came with it.

I then done the Windows 10 upgrade and everything went fine, memory was running at 2133mhz as stated.

As with all new OS I like to clean install so I completed that process along with BIOS updates to ensure everything was in good condition. However on completion my memory is now only running at 1600mhz.

I've gone into the BIOS and there are no memory/CPU settings.

Any ideas what could cause this, have I missed a driver somewhere or are there any settings in Windows 10 needing adjusted?

The laptop is an Asus G750JW.

Please help

Thanks

Seems like the BIOS update wasn't for the better?

Can you go back a version or two and see if you have memory options available?

Did you try resetting the BIOS to defaults (on all available screens)?

Is the RAM possibly defective? Try running memtest overnight to see if anything shows up.

Good luck.

 

Welcome to Asus World, hmoodie. I still have a pair of low volt ram sticks I bought that I can't use on any Asus laptop. I bought them two years ago, and sent a request to support, expecting it to be sorted out by the end of the afternoon.

But it is not possible for Asus to do this, because, and I've had this from different support guys two times now.. once for each Asus laptop... They say that "The ram timing is locked, to prevent people from overclocking the cpu".

When I try to explain that I don't like either accidental or intentional stupidity that simplifies things for them, and makes things difficult for me -- they tend to cut me off with a lecture on the glory of Internet Explorer and Microsoft embedded products.

But yes - Asus lock their bios-timing and refuse to change the ram timings to "obey SPD table".

And the reason for that is that they have a hard-programmed table set of bus frequencies and multipliers for some of their models, or have had that for some of their models many years ago. So if they allow the newer platforms to use the spd-tables with the dynamic bus-frequencies - they risk that these models overclock and underclock, thanks to a second set of forced timings.

And they can't figure it out. It'd take me ****ing ten minutes with the bios tools. And Asus have been screwing around for two years. Hell - before that it was the locked sata2 settings. They'd got it into their heads that mainboards that supported sata3 - might actually burn up if they enabled the function in the bios. This made complete sense to the guys at Asus I talked with.

They're complete idiots. I've said so before - they have decent hardware, they have good enough chassis-construction. And the best medium-level cooling solutions on the market - that's why I put up with this crap. But they must literally have a monkey on the bios-settings. It's literally worse than if they just used the default settings from Intel - that is, on the same generation of hardware, rather than for a previous version.

Still - I guess if people do write to Asus and tell them to get their heads out of their arses - they can probably get a semi-competent person to spend ten minutes with the bios-settings and sort this out. It would obviously be at great expense! But since it PISSES OFF EVERY SINGLE ASUS CUSTOMER, I guess this exorbitant fee for ten minutes of semi-competence could actually be worth it.

But until people do write to AsusWorld to inject new information into their bubble, this would be simply an expense that would please one single enthusiast. And Asus won't do something like that, even if it really would take 10 minutes and cost 4 dollars.

 

The problem is, everything was fine before the clean install, CPU-Z and Win10 Task Manager bother showed 2133mhz. Only since the BIOS and Win10 clean install has it now become an issue.

Can drivers affect this, maybe mobo or chipset drivers?

hmoodie, you can download your older BIOS version, and revert to it, that should restore your 2133mhz memory.

Use the cmd window, maybe Run As Administrator just in case, and use the /nodate option to allow you to flash an older BIOS:

C:\directorywithwinflash\winflash /nodate

You can also add the /nodate option to the shortcut command line, works fine that way too.

If you prefer booting up outside Windows to do your flash, you can create a USB boot drive and run the winflash cmd with /nodate from there.

I don't think you can force an older BIOS update from within the BIOS flash tool...

You might post the info / procedure to the Asus ROG webiste when you get it all working, use snipping tool to grab screen shots.

Good luck

 

Hmscott, I've seen you on the ROG forum, I'm Liger (username).

You couldn't possibly give me a step by step on how to go to a previous version of the BIOS, I'm a bit of a worrier when dealing with the BIOS.

All help very much appreciated!

hmoodie, you already did it once for 210, it will be the same for the older BIOS version, just add the winflash option /nodate to the command line.

 

Thanks again for replying mate, I done it using the Flash Utility on Asus Download site. I just opened an application and pointed it to the 210 BIOS.

Do I use the same BIOS app but point it to the older BIOS file? It gives a warning stating you are flashing with an older BIOS or something

You need a command shell with admin privileges.. think there's a button for it in the start-menu in win10. Then find the directory you have winflash in.. "cd \Bios\Winflash".. something like that? (you can use tab to complete the directory names after a few letters). And then run the program with the /switch. You have to do that, and not fiddle around with any shortcut extras, and so on, because of how bash will pass parameters... In the future there will be robots, and they're going to suck so much..

Aargh. Stop that positive attitude, right now!

No on asus - but it is possible in general now. And it's difficult to tell whether they're using some of the system-level interfaces for acpi through intel's extended firmware (through the efi bios layer), or whether they rely on the bios-settings being unchanged - and only touch the power-saving functions for some specific programs (like the smartgesture thing that controls the processor speed... yes, I kid you not - whenever you engage a two-finger gesture, your processor speed will be bumped). But it sort of seems it's both with asus - that some of their models use the newer interfaces - but that they essentially want to make sure that if you don't have the chipset drivers installed, that the computer functions as you'd expect anyway. Or that in practice, they specify the bios/basic firmware package for ram timing, bus and cpu-speed, and so on. And then add certain things with software control later on. So the cpu-states you can set on the ROG laptops with that app obey limits set on beforehand in the bios, that would normally occur on the right loads, just with higher response latency.. because the cpu&core load limits are chosen with a pair of 1d6 dice or something like that..

..I don't know.. Tell me something - do people genuinely believe that a processing element connected to a bus polling interrupts at more than 800 times a second actually needs to be boosted on "beforehand" - when playing games, or whatever - to not be slow somehow? That if the processor isn't put into overdrive before the game starts - that the performance will drop.. every time you stand still and don't move your mouse-pointer... or something like that?

 

RAM speed is entirely dependent on the BIOS, and the compatibility between your motherboard and the RAM.

RAM speed does not throttle. It is not affected by the OS, or drivers. It is entirely dependent on communication between the BIOS and the RAM sticks themselves. It is your BIOS update that screwed up the RAM timings. You're going down the right path by trying to revert back to an older BIOS version.

 

Thank you, I'm trying the /nodate command now but getting the error that its not a recognised command, any ideas?

Does this look like its running as it should?

 

Yup tha's running normally....

 

Thanks Tom

 

Apart from that they've set tRas very high to compensate for cas 11 likely causing instability in some configs. Which results in very high tRfc[read: ready-delay for each memory operation] -- no problems, no ... *cries*
