I have a question. Can an i5 Run ram at 1333mhz?

We just figured out how to get into the advanced bios for HP's stuff (or at least the envy computers).



Lots of options. One of them is setting ram speed.

HP gives you 1333mhz ram but sets the ram speed at 1066 in the bios for i3/i5s.

I want to know what would happen if I changed the ram speed in the bios to 1333mhz.


Would it still throttle back down to 1066 because an i5 can't use it?

Would it work?

Would my computer screen explode into an angry garbled mess that is locking up due to the ram and the processor no longer agreeing? And if that happened would I be able to at least make it back into the bios to fix the issue?

 

1066MHz is the upper limit for Arrandale (first gen i3/i5), I believe.

It's probably cheaper for HP to buy huge amounts of 1333 and put it in all their machines, as it will clock down to 1066 automatically if that's all the chipset supports.

 

Ok. So it won't hurt to "try" setting the bios to run it at 1333.

It'll just clock back down to 1066?

 

FWIW, when I do that with my desktop I just get a blue screen whenever windows starts loading or first gets to the desktop. When I switch back it works fine.

 

heh. Well guess I'll see what happens.

if I get a BSOD ok. I can still easily reach the bios. Man kinda annoying that you have to do F10 then like half a second later hit A to turn on the advanced bios in HP computers.

or at least envy computers (not sure what all this works on)

 

Here is the datasheet for your processor (assuming the one in your sig is what you're on about), where you can see it only supports 1066MHz memory.

I'm a bit confused as to why the BIOS will even give you 1333 as an option; perhaps similar chipsets were used for the higher end i7 quads (which afaik do support 1333MHz).

I have to say this sounds like a distinct possibility. Probably best to leave it alone.

 

Hmmm. yeah. might as well not mess with it.


The reason why 1333 is an option is that there are i7 envy 14s with the hybrid gpu shut off (which is also an option in the bios like with the acer 3820tgs and their bios).

 

The memory controller only supports 1066 RAM natively.

For the question of RAM OC, like X58 chipset only supports 1066 RAM natively as well. If you try to manually set the timings, unless you have high end RAM, it will most likely BSOD or not even boot at all.

 

Well then. *completely throws that idea out the window*


now to figure out what these four different temperature settings mean and if that 85 throttle is the actual throttle temp (it probably is). 100 for emergency shut down.

55 for the fans to kick into high but that high isn't full blast and there's no option for that. Maybe it's just a time thing or a fast temperature increase....

 

Sorry, no information for you on your specific problem other than:

Since the cpu doesn't support it, I would change it.

However, I am drawn to this 'secret' advanced BIOS options keyboard shortcut - would this work on an ASUS U30Jc?

Or, does anyone know any advanced BIOS entry point for Asus products?

With the HM55 Chipset, I'm thinking if I could turn off C States (when I needed to...) I wouldn't have to suffer slow HDD/SSD speeds anymore.

Thanks for any info and thanks for giving me the idea of the possibility that something like this might exist in all BIOS's too.

 

This is only for Insyde bios that the envy (and some other HP laptops are using, I think)


You hit F10 and then hit a immediately afterwards.


in practice it's more like f10,a,f10,a,f10,a as fast as you can when you turn the computer on.

 

Thank for replying.

I just tried it on my Asus U30Jc (just once though...) and although it is F2 instead of F10, it still didn't work.

Interesting though that something like this is available - I'm guessing the UEFI 'bios' will allow that for all systems in the future though.
