G51VX How Fast / Hot Can it Get (CPU Overclock)

Hiyas,

First, I LOVE [thread=401345]Tev's Guide[/thread]. Great resource for anyone.

Second, I am trying to see how much I can push (overclock) my laptop safely, and I would like to compare it to what you all have. This is solely for the CPU as there is more variety than with the GPU.

This is not about benchmarks, rather, it is about how high one can safely overclock their CPU.

I am compiling a list of data that I create as well as get input from you all, to see how I stand up, and hopefully shine some light for others to see how far they can push, or if I, or anyone, received a bum CPU.

Please post the information below and I will add it to this spreadsheet.

- Type of G51VX (A1, RX05, X1A, X2A) (Used to identify the CPU, if it is custom, please let me know.)
- CPU Speed
- CPU Voltage
- OS (not sure if this is relevant)
- Cooler (with or without one)
- Load (Idle, Low (i.e. web browsing), Game (with high settings), Max (i.e. Orthos), BSoD)
- Ambient Temp
- CPU Core0 Temp
- CPU Core1 Temp
- GPU Temp (for reference)


*All in Degrees C except Ambient Temp (which is in F)

When / if I get more input, I can stick this on a google Excel App so people can sort / view it as they please, and maybe change the view up (i.e. with averages).

Please help me with this, and also help the other viewers here!

Note: I have read through many posts here and Tev's guide and other sites where people say their Temps; however, it is rather difficult to compile them all, and I am unsure of their testing methods, other variables, and exact numbers.

Note2: I am obviously new here, so please let me know if I am out of line in this post or any way I can improve.

Thank you all,
~snake

CPU Core1 Temp: 69
GPU Temp: 88

All of these are at stock GPU clocks running at 0.90/0.75/0.75/0.70 Extra/3D/Throttle/2D

 

Updated.

I was thinking of adding GPU Voltages and Clocks, however I did not think it would really be of huge benefit, when compared to CPU, since there is a much wider range.

That and most people (that I know of) do not really push the GPU to the limits when compared to the CPU.

Though I can of course add them.

So I don't forget (since it is all automated now), I only overclock my GPU to 600 / 960 / 1500 Core / Memory / Shader when testing and playing games.

This is my temperature, with normal CPU clock [email protected], Over clocked GPU. im so surprise that can reach such a benchmark. 6k

 

I laughed at how Soviet managed to sneak into the table.

 

I lol'd =D

 

@putochip

Use 06.....noone in the Asus forums at least use Vantage so its kinda wasted in terms of comparison purposes

 

Alright, well I've found a validated CPU-Z dump of someone with a [email protected], so I think that overvolting and over clocking further is definitely a possibility. I will at some point test this theory to see if I can push the P8700 to 3.2+GHz

 

how are you overvolting ^^^?
is it in RMclock or other software?

Or is a a hardware mod?

 

Crystal CPUID http://crystalmark.info/software/CrystalCPUID/index-e.html it is part of Tev's guide (well, I'm doing it in reverse...) http://forum.notebookreview.com/showthread.php?t=401345 NOTE: I'm only doing this because my temps when OC'd to the max are more than satisfactory (63C Max after an hour of orthos, mostly idling at 60-61C)

 

thanks, I was using RMclock and the highest VID is not high enough for me.
Hopefully crystal CPUID lets me take it higher. thanks again +rep

EDIT: crystal CPUID doesn't let me overvolt any more than RMclock does. this is not great
I have to know do a hardware mod for +0.4V which is not really fun.

 

RAM is a factor, too. I'm not sure of the specifics, but a slower-rated RAM will give more overclock.

(I think)

 

50 points from Gryffindor.

 

Darn. What's the right answer then? I do remember from someone--I think Clutch--saying he got a higher overclock by swapping out his old RAM.

 

you need to flash your ram to lower speeds.

say you have 800mhz DDR2 ram, flash it to 533mhz.
now when you overclock your FSB the ram will be going back to it's stock frequency. So you can overclock further since your ram will be very stable.


use SPDtool to flash your ram, or even better is thaiphoon burner.
But thaiphoon burner is only a trial version for 15 days or something unless you want to pay.

Be carefull when you flash your ram, don't do anything crazy.

 

Whoa, I thought I was going through dejavu there for a second, haha. Yes, that is correct, moral hazard. 50 points for Slytherin.

 

Well, a lower-clocked RAM would still give a better overclock, right? You're just cutting out the flashing and spending more money.

It should have only been 25 points, you evil man.

 

Also it's worth knowing that some ram has write protection enabled, for example I'v notice all of my samsung ram has it.

I'v tried to disable the WP by doing a mod to my ram but it failed.
If you want to see why then look at this thread:
http://forum.notebookreview.com/showthread.php?t=408349

If you have WP enabled then you cannot flash your ram.

 

no, that's not true.

Do you think you can buy 533mhz ram and run it @800mhz?

you have to buy 800mhz ram, lower it's frequency to 533mhz or 667mhz.
then when you overclock your FSB the ram will be clocked back up to >800mhz.


EDIT:
lets for simplicity say that 800mhz ram will only handle 800mhz and 667mhz ram will only handle 667mhz.

If you buy 667mhz and overclock your FSB, the ram will now run @800mhz. It will be unstable.

If you buy 800mhz, flash it to 667mhz. overclock your FSB, the ram will run @800mhz and be STABLE.
Since the 800mhz ram can run @800mhz and the 667mhz ram is unstable @800mhz.

 

RAM rated at say 667MHz won't do well if flashed to 800MHz simply because it's not rated for that speed. Buying matching spec RAM and flashing it down while you overclock the entire FSB to bring the RAM frequency back to factory will be a lot more stable.

 

Oh, I see. You're right Soviet, it's fifty points.

 

I think I also have a hardware solution for this. When I used to FSB overclock my QX9300 to 3.3GHz and my RAM to 1200MHz, the RAM would get really hot, and the tight timings doesn't exactly help either. The aluminium heatsinks on my RAM did it's job of keeping my memory in check. But at that time, I did not incorporate the original RAM copper mod at the time, or the revised version of the RAM copper mod that I have installed now. My northbridge also did not have the copper mod; it only had a thermal pad upgrade. Back then, I had to keep a close eye on my CPU temperature as it is also correlated, though loosely, with the RAM and northbridge maximum temperature tolerance threshold. This is how I was able to attain the highest 3DMark'06 record for a mobile CPU/single GPU setup. But like I explained before, I'm no longer a benchmarker, rather just a simple crazy Russian that helps/trolls random forums.

Like I mentioned, there is also a thermal factor when FSB overclocking. Not only do you need to keep the CPU cool, but also the RAM and the northbridge. If I were to do that same fateful benchmark all over again with my notebook as it is now, I would most likely break my record again due to the greatly increased thermal stability. But what does this mean for you guys? It means that if you want a very stable overclock, then make sure all the components that are involved are properly cooled. Oh, and before I sign this post off, GPU overclocking is slightly affected when overclocking the entire FSB. The PM45 has only so much bandwidth.

I've said too much already. This post is KGB confidential.

 

You're kidding, right? Of course you're still a benchmarker.

 

I'm a tempmarker now. I've given up my benchmarking days a long time ago. Unless you consider the frame count in my Furmark tests to be... wait a minute.

 

Measuring your best temperature = type of benchmarking.

We still love you.

Is there any way to get SetFSB to auto OC at startup? Maybe this is an obvious question, but I used the Google on the interweb and didn't find an obvious answer.

I can safely get my P8700 in my x1a to 3.0 (max temp = 65 on core 1...haven't tried beyond that), but it resets to stock clocks when i reboot.

It's just irritating re-OCing it bit by bit every time.

 

Did you read Tev's guide?

 

Looks like my CPU maxes at 3.16 GHz in orthos, kinda disappointing. I can benchmark it at 3.2 GHz just fine but knowing it fails in orthos means it's not stable. Bummer, was hoping to hit at least 3.2 stable. GPU seems to overclock really well though, it has no problem hitting 610/950/1525. I'm pretty sure I can push it quite a bit further but the temperatures are prohibitive until I get a cooling pad for it.

 

Yes, but no....sorry, I searched and searched the first section under setfsb and blew off the part that reads, "Getting SetFSB and Crystal CPUID to Start at Boot."

Yeah, I went to college.

 

I went to kindergarten.
