Highest Overclocks on G50VT?

For the people who have the X6, what's the highest you could get on the 2.53 GHz CPU?

Also, the general consensus on the 9800m GS is that you can get it to 600/800 like the GTS. Anyone gotten higher safely?

 

Your overclock is going to be limited by the ram unless the cpu is a really sucky core. Based on my ram not working past 920Mhz (460 actual) puts the bus speed to 306Mhz Actual the X6's cpu in my unit would clock to 2907 Mhz. Every single ram stick to ever be produced is different and for me seems to be the limit as I have run into the same limit on 2 processors P7450 and T9600.

The factory overclock will get it to 2793mhz.

The video cards ram is 800mhz stock so mentioning it goes to no point. Not everyone will be able to run at the GTS clocks. It varies by every single chip to ever come off the line. I personally havent messed with shaders but motok's pushed his card pretty far. Ive run 620 Core and the GTS 1500 Mhz Shader core, The 620 is pushing it on myne so i run the GTS 600 instead.

 

Interesting. I get really good overclocks on my G1S; 425/700 to 550/900. Was hoping to get even better on a machine that doesn't have thermal issues. The G1S has serious thermal issues that I've managed to solve.

 

I should add yes the gpu ram is overclockable and people have. I havent but the GTS clocks on the ram are the same as GS was my point.

 

I've gotten pretty high with my gpu and have had no artifacts or black screens yet. Its in my sig.

 

Interesting. Guess I'll have to play around with it. I'm waiting for the tracking info to say Out for Delivery so I can hop in my car and go find it

 

Look my OC results

 

Yea tavara my oc was based on your clocks, I think thats the highest we can push the shader clock(1670). I started to receive a constant black screen at that and went down to 1550 lol. I still have no idea how your gpu remains so cool though.

 

Crap, tavara!

After doing the GTS flash and putting my X6 on Turbo Extreme, I get 8875 3DMark06 points at 1280x1024.

I haven't tried SetFSB and more overclocking for the GPU yet since Im still transferring all my old info from my G1S.

It feels like there is lots of room left though seeing as how I haven't done a fresh Windows install and the computer didn't get past warm on the bottom during 3DMark06. This thing runs cool! The fan barely went on high. In my G1S, during the first 10 secs of 3DMark06, it screams!

 

Grab driver sweeper and either dox 182.05 (if u didnt via the bios guide) or 185.85. Driver sweep nvidia display in safe mode reboot and install. After the cpu overclock id expect 9300 or so maybe 9500.

 

I did install the 185.85 driver. The issue might be that I didn't do a fresh Windows install, but who knows. Also I hadn't uninstalled the ASUS crapware before doing it.

 

I run with the crapware, benched in 7 without it gained 1 point.......
Clean driver install is everything and dox 185.85 better then stock 185.85. Driver sweeper for the win.

 

Thanks man!

LOL, turns out I installed the basic NVidia driver by mistake instead of Dox's.

Check the glory:



Also, Crysis at 1680x1050 averaging 32 fps :

 

My GPU doesn't get any hotter than 86c after flashing to GTS, but I don't need any extra power so I'll leave the OC'ing alone until I do

 

Interesting that your GPU is being reported as a 9800 GT.

What settings are you using in Crysis, particularly xAA?

 

Yeah it is odd. I hear that for some G50V/VT owners, it says GTS, for some it says GS, and for some it says GT.

 

Stock it will say GS, after the bios flash and with dox drivers it says GT though ive flashed the bios back without changing the drivers and it still said GT.

I will get around to testing it at some point but i when i looked through the list on DOX it didnt looked like GS was even on the support list.

The bios itself is actually an edited GS bios and the bios still says GS so i believe it is mostly driver related. I havent tried editing the bios to say GTS straight out of fear lol.

 

Pushed my CPU to 2.9GHz and it was mostly stable, but it did crash twice, so I set it back to Extreme Turbo for gaming.

Either way, it didn't help much since most games don't even do 70% of the CPU. Not even Crysis.

 

Far Cry 2 does on myne at its stock 2.8. GTA 4 uses 100% on anything short of a supercomputer lol.

 

Assassin's Creed pushes my little 2.4 cpu to 90%.

 

Yeah, some games do, but most don't. The games I'm playing that do push it to the max still run between 40-60 fps so its not a big deal.

 

when your overclocking the video card the core and shader need to remain at the same ratio, otherwise you create instability. the shader clocks should be 2.5x the core for the 9800 series. So for every 10mhz core bump the shader clock should go up 25mhz.

at 650mhz your shader should be set at 1625mhz.

 

lol I never knew that, good to know. I also think that the shader should not be pushed past 1650 as I have found that to be the stable point.

 

What do you guys use to OC the card? The NTune Performance menu item gives me BSOD on this computer.

 

It sounds like most people flash the video card's firmware to a modded 9800m gs with gts speed or maybe a gts firmware. Seems like a reasonable way to get gts performance from these notebooks - although, what are we talking about in performance 5-10%?

 

10-15%, 15 for me

 

Use ATi Tool under xp or 32 bit vista, 0.27 when it comes out of beta works on vista x64 but it has clocking issues omn the g50 atm.

Edit the bios and flash it once u know what u want to run it at.

 

Not saying your wrong, but where did you get this info? Are you saying '530 core / 1500 shader' is less stable than '530 core / 1590 shader'?

What kind of instability btw? Would it be the black screen then recovering, artifacts, or the total freeze?

 

Interesting, there does appear to be a correlation between the stock core shader clocks.

1325/530 = 2.5
1500/600 = 2.5

 

Isn't the GTS 1500/630 though?

 

Nope lol, and a quick google (outside the fact im flashed right now) reveals 1500/600. Possibly explains why i have issue anywhere over 620 core clock with the shaders flashed 1500.

Good info on that 2.5 ratio of Shaders/Core will give it a shot later with the lower of some of the shader clocks ive seen.

 

very interesting find

 

Dude mentioned it on the other page, i had never given it thought and quick math shows the ratio he had. Most likely has to do with the communication between the parts of the chip, the multiplier is fixed.

I havent gotten around to trying a better overclock yet.

 

dont doubt the guru lol i stumbled upon this with my 9600m, i was getting very inconsistent overclocks like you were with the black screen. Nvidia cards have been this way since the 8xxx series and the introduction of the shader cores. the ratio is different for the 8series but the ratio concept still applies

you can skew the ratio, but the more skewed it becomes the more likely the card will fail

 

I used nTune for my old 8600m GT and that one adjusted the shader clocks automatically so I never had to worry about that.

 

ClutchX2, I have been trying to figure out how to modify my bios on my G50VT-X1 to set the clock speed of my cpu to the direct console extreme overclock settings but I cant figure it out or find any worthwhile guides as to how I would do it. Here is what I have:



I am running BIOS version 213. Could you please help me with this, maybe lead me to some good tutorials or something?

 

Note that your screen shot was at idle when the cpu down throttled to a 6x multiplier. When trying to get an accurate screenshot out of cpu-z on a speed stepping processor try running something cpu intensive in the background, the wei score measurement is enough to kick it up to stock speed.

Download the latest SetFSB and use PLL ICS9LPR604AGLF. Note that setfsb doesnt show the proper speed (200mhz rather then 266mhz) due to its math works on a 1:2 fsb ram ratio and the G50 is 2:3. Know that the slider value doesnt corrospond to speed directly.

The FSB value 1066mhz is actually quad data rate the real speed is 266mhz as you can see in CPU-Z with Direct Console you can push it up to 294Mhz.

Hit getfsb then bump the slider up a bit hit set fsb and then check the fsb with cpu-z. Once you start getting high you will want todo stability tests. http://www.ultimate-filez.com/files/IntelBurnTest.zip will work well it stresses the processor more then in normal use.

The ram is the real limit most of the time in the overclock I get my FSB around 306Mhz which pushed the P7450 from 2.13 to 2.45Ghz not everyone has had that much luck with it. The slider value that gets the G50's to 306Mhz is 500. If you go too high you might instantly crash, if its a little too high it might crash after a few minutes or during the stability test.

If you have a bsod on the reboot, then just boot into safe mode (f8) and then reboot and you should be fine, worked for me every time.

 

Yes I know, sorry about that. I can OC with setfsb stable at 2.9ghz, but I want to modify the bios so I no longer have to do it at a software level. Think you could help me, or work with me on figuring it out?

 

Outside of the possibilities of doing that, I dont believe anyone here does. SETFSB AutoTool v3 from these forums is a way to set it on boot, note that always running at this speed is a good way to shorten ram life as its the weakest part of the system though 4GB of DDR2 is dirt cheap.

Im working on a replacement for DirectConsole that will use setfsb in the background.

 

It looks nice, I can't wait for you to release it. Let me know if you need help testing it. I would be more than happy to.

Do you know right off hand what the correct PLL is for the Asus G50VT-X1?

 

My prior post to you i believe had it but off the top of my head ICS9LPR604AGLF

 

BTW My video card overclock highest stable was 640-800-1600 @ 1.15v

 

Cool. I haven't tried to OC the video yet.

 

My sig has the clocks where I can run with comfortable temps in a rather hot bedroom during the summer.

Looking forward to installing 186.03 drivers, as those are supposedly nearly the same performance but a lot cooler.

 

My G1S could hold good overclocks in the winter and fall, but come summer, I needed the laptop cooler thing.

 

Maybe the motherboards are different (though I don't think so), but my G50V-A1 has been running SetFSB on every boot since going on a year (well, ten months) using PLL code ICS9LPR363DGLF which reads the correct FSB frequency. You can try it.

As far as optimal overclocking you really have to spend some time looking for a sweet spot, for me I had been jumping back and forth between super cool stock 3.06GHz to a blistering hot 3.59GHz. Finally I spent a day going through different voltage and FSB combinations until I found my cpu's sweet spot which gives me barely over stock temps and runs at a super stable (tested on p95 with small FFT's) 3.31GHz around the clock. I've never had a problem with temps since.

Right now it is running at about 109-F (43-C) sitting on my lap, no cooler.

Here are my settings


Overclocking Settings - Tested

FSB------Eff.---------------Max
Clock----Clock---VID-------Temp
(MHz)----(MHz)--(V)--------(F)

266.3----3059----1.1000----

280.1----3221----1.1250----186

288.4----3317----1.1500----190

299.2----3440----1.2000----202

307.5----3536----1.2375----205



Also:

I use CPUGenie to control the voltage profiles, and SetFSB Tray for the automatic overclock.

 

My G50VT-A2 which running on [email protected] stock, I can not manage to overclock it over 3.0Ghz.

No matter how I combine SetFSB and Crystal CPUID, I can only archive as following:
CPU FSB: 317Mhz
CPU Multiply: 9.0
RAM Bus ~950Mhz

With these settings, I can pass Intelburntest 2 phrases within 3 minutes.

I think that the problem is P9500 can not run over 2900Mhz with 1.088 voltages

Also, I can use SPDtools to force RAM to run at 667 bus to make sure after overclocked at above ~800Mhz will be fine, so the remain problem is certainly on CPU voltage.

It will be great if anyone can help me out.

Thanks,
