Overclock And DRAM Frequency

[bludgard69]

I heard that notebooks shouldn't be oc-ed,yet I had to experiment.I got the 1.6G up to 1.9G.Everything ran smooth.Temps remained the same.Prime95 ran torture test for 4 hours and no problems.Performance was increased and stable. My only concern is that the DRAM frequency went over the specified max(333mhz) to like 360mhz.I have since refrained from oc-ing for reasons of possibly damaging the DDR2.Are my concerns over this legitamate?I also ran m mem diagnostics_pagefile-off,extended.No issues. I'm getting my temps and speeds from CPUID products.I think they are pretty accurate. Thanks for any insight.

Dunnot think so....! Maybe some screenshots and programs used will help more?

Yes, they are legitimate concerns. However, it does depend upon the type of ram you are using. Some ram can take running out of spec better than other types. Since this:

I heard that notebooks shouldn't be oc-ed...

and you are comfortable in doing it to your notebook, then you should go into your bios and check the ram timings and set the frequency back one step (from 333MHz to 266MHz -- if you can even do it with your laptop) That way, when you increase the clock speed, the ram will increase too, but not over the 333MHz which is the spec for your DDR2-667 ram)

If I understand correctly,I can't change BIOS on this notebook.It's why I used SETFSB.I've tried AMD Overdrive but most controls were greyed out.BIOS again is my guess.By the way,thanks for response.

Yeah, I didn't think you'd have much chance in changing the BIOS.

AMD Overdrive is supposed to be for the 7-Series chipset from AMD, so it wouldn't surprise me that most of the features are grayed out.

I've never heard of SETFSB, but if it has an option to set the ram frequency, then set it one step back from 333MHz, or to 266MHz)

Hi,again mpcrsc562.There are no control settings.I think only Front side bus.Thanks again for response.SetFSB_HomePage

Man...............I'm gonna have to get a desktop to play with.Too many restrictions on Laptop.This is going to turn out to be an exspensive hooby.Could spend money and time on worse things............

It's not the restrictions of a laptop, per se, it is that you have a store bought pc mass produced by a major pc manufacturer. If you had an Acer, HP, Dell, etc, desktop, you'd probably still be hampered in what you could do to it (by way of bios, overclocking, etc) without the use of some 3rd party software (as you have used with the SETFSB)

Thanks again for your timely and applicable response,mpcrsc562.

I used SetFSB on an HP Dv5000 series few years ago. That was working fine, i had to borrow the value from another similar HP Computer, 'cause could get the proper value working well. As said mpcrsc562 some stick Ram are faster than others.

Bios are most locked in Laptop, and modded bios that can be found are quite dangerous to use if you do not know how to revert back to original one, you have to find the same modded bios as the one installed to trick the thing.

You can also use something like RightMark CPU Clock Utility (RMClock) aswell here.

But i don't think both with SetFsb can be run together.

Hello,again.If I double my DDR,will my max. frequency still remain the same?(DDR2@333Mhz).Or is there some kind of esoteric formula that's involved?Thanks for any insight.

Hi bludgard,

Memory is rated; RAM is not set at a certain speed. This means your 333MHz DDR will operate at a minimum of 333MHz, given stock voltage. It can run faster, and it can also run slower... by how much all depends on the quality of the IC's on the sticks.

In terms of memory, if you're able to run it faster without having to increase voltage, then you're not going to do any harm. The only questions are, "will it, and is it stable at this frequency?" If it's stable, with memtest before Windows, and either Orthos (dual Orthos if you have a quad) or Linpack within Windows, then you can run without worry of corrupting your OS.

It may run warmer, but not by a noticeable amount. However, when it comes to heat, every little bit hurts, so you do still have to be mindful of system temps as laptops are the worst environments in which to overclock... my advice on overclocking the RAM is the same as it was for overclocking your video card... it's not worth it... the laptop is too small, and the minimal gains you get aren't worth the risks you take given the machine's specs.

If you double the amount of RAM you have with more 333MHz RAM, they will still all operate at 333MHz. If you add RAM that is faster, they will all still operate at 333MHz (defaulting to the speed of the slowest stick), or whatever frequency you set.

Thank you for breaking it down for me.I've searched for this information-to no avail.I get specs and more specs,but no real working knowledge. Mabe I wasn't looking in the right place.Yea,I did some soul searching and commited to plan on building a suitable machine for play.(COMMITED TO PLAN ON)Sounds like me.Boy,I'll run a subject into the ground,huh?See ya again.
