G50VT 9800M GS Overclocking?

it does feel like there is a bit of headroom in the GTS speeds. i ran furmark and it hit 89 degrees. games dont go higher than 86. even my GTX 260 gets hotter than that when running furmark.

if i could just work out that setfsb i reckon 10k could go down in 3dmark06

 

Hasn't happened again. It was the first thing I did, so maybe it's broken into it.

 

You get 15C higher then me!what your CPU

 

86C max on FEAR 2, and easily 4-5FPS higher than what I was getting previously.

 

Does this also increase the votalge to 1.1 or do we still have to make another change?

thanks

 

@joeelmex, yup the voltage is modified

Ran the Devil May Cry 4 benchmark, got better performance than usual.

88C max, and there was some noticeable screen tearing in Scene 3, but not in the other parts of the test. Might drop the core a little bit like electronicrice.

 

CPU is T9600 oc'ed to 3.08
g50vt-a1

overall it sounds like good results guys

 

My cooling is definitely not as good, I only have a P8400.

 

9,170 3dMark @ 1366x768, not bad at all. Temps hit a max of 85C.

 

I'm geting 9622 3DMark at 1280x1024, max temp. 76C

 

Did you modify your case or replace your thermal compound? Because I've no idea how you're getting the temps you're getting.

 

9704 at 1280x1024, max 86c
gotta work out how to oc the CPU in xp.. im sure that will add a bit more

 

Strange that my score is so low. I wonder if 1366x768 is somehow an inefficient resolution for 3dmark..

EDIT: Wow, I just hooked up my old monitor so I could test 1280x1024, and I only get 8563...

My comp is gimped =(

 

Could a difference in ambient temperatures explain some of the difference in GPU temps? Also, is anyone using an external cooler?

 

ca36gtp are you running 3dmark06 in xp 32bit or vista 64bit?

i get 8999 in vista 64bit and 9704 in xp 32bit. both 1280x1024. CPU is oc'ed under vista from 2.8 to 3.08. under xp its 2.8.

vista slows it down a bit.

No external cooler here. but 75 does seem too low for a lappy. is it a 17inch lappy?

 

Vista x64. That makes me feel a little better. The more reasonable difference is probably from the CPU.

 

You mean 2.9 Ghz?

 

so close yet so far...

trying latest drivers, might even try to sneak the GTS up a bit and see if i can hit 10k

 

ATItool stressing temps w/ GTS volt/clocks on the X1:

After 1 min: 73C
2 min: 78C 3 min: 81C
4 min: 83C 5 min: 86C (max fan speed kicked in here)
6 min: 85C 7 min: 86C
8 min: 86C 9 min: 87C
10 min: 86C

A little warm but not excessively so. Got some MX-2 coming in a few days to drop it down a little.

 

CA36GTP, definitely keen on seeing the temps after paste... hope it drops a few as i will do the same...

such a good overclock from GS to GTS, makes a notable difference in many games.

 

Can anyone post the vbios to flash for the 9800m GS to GTS clock settings? I've tried the link that was posted before (rapidshare.com/files/193610043/9800GS_GPU_BIOS.rom.html) and it says it can't download it.

 

finally hit 10k, had to push the GTS up a bit.

Here, I believe this is the modified BIOS...

Wow betc, thats impressing!

Thats really good numbers! How is the "in game" perfomance and temperatures? Do you have any artifacts or other strange bugs?

 

i have only put it up to 1550 and 850 to reach 10k. normally its on 600, 1500 and 800. no artifacts, no reboots, no freezes.

i ran furmark when oc'ed and it went to 92c, so its pushing a bit. mind you my ambient house temp is 30c so that wouldnt help.

waiting to see how CA36GTP's temps are after new thermal paste before leaving it at that temp

Tested in... (long 2+ hour game sessions...)
R6 Vegas, FarCry2, X3:TC

going to run some benchmarks on crysis and see how it goes
Crysis
1.2.1, high, xp, 1024x768 gpu_benchmark, noaa. GTS speed, 3.1Ghz t9600
40.26fps

with newer 182 nvidia drivers its
9917 3DMarks.. so close at stock GTS speeds

 

So I tried to flash my vbios and got an EEPROM error saying that it's write protected

I tried with 3 different flash drives, 2 of which won't even boot. Any idea's guys? Thanks

 

here are same benchmark- look my signature

 

not sure whats happening frostbit3, i made my Compact Flash card bootable via that HP thing, stuck nvflash and the roms on there. booted to 98, ran nvflash 9800gts.rom and it went straight on...


insane clock tavara, im not game to go that high... have you changed thermal paste on the vid card or does your just run really cool?

 

Got the modded BIOS, read the tutorial by big spin and I am going to give it a whirl and see how my lappy deals with the bios that is provided in this thread. I will come back with temps and numbers!

Ok well I have run into a brick wall. I formatted the USB key and used the boot files provided, but for some reason cannot get my lappy to boot from the key so I can flash my card. I changed the first boot option to removable drive, but nothing. What am I missing here guys? I tried it on both the right and left sides of the computer. Someone... anyone?

 

there is 'boot order' and 'HDD order'
you need to change the 'HDD order' as well

set the USB card before the 2 HDDs

 

Thank you so much now I can boot just fine although I have run into another problem. When I try to backup my bios or flash the new one on I get this error, "Load Error: no DPMI memory"

Any ideas?

 

no idea there mate

 

ok supposedly you can OC the X5 with the 9800M GPU but i am running speed fan and it's giving me some wicked high temps for my GPU... like right now for example it's at 48C and it's just sitting there now if i OC this thing it'd probably catch fire any explanation for this?

 

REPS to whoever can put together a step by step guide to flashing to GTS speeds to help me and anybody else who wants to turn their G50 into an insane gaming machine!

 

The heatsink is split into two parts, with the GPU part looking more difficult to remove. Looks like the case itself needs to come apart, not just the bottom panel.

Finally got my machine flashed up although it runs way too hot for my liking...

I just ran 3dmark05 and one go through got me up to 90C oh boy I think that i too much! Before my max temp was 76C. I did however get 16092 points!

Just ran some more stress testing with everything ramped up to the max and although the performance is great after 15 mins I hit 93C on the card. I don't want to waste my computer so I guess I am going to put the old bios on or maybe mess around with a lower over clock with no volt mod. Thats just too ed hot.

 

Oh come on don't let this discussion disappear! Discuss!

My max temp was too high for my liking to I flashed back to the original BIOS I had saved before I flashed and now with stock clocks my max temp is the same as the GTS BIOS! I am hitting 93C... so what do you guys think?

Well it looks like I am talking to myself, but maybe someone in the future will read this and it will help them. The BIOS flash has not changed my temps what so ever it looks like; in games I get the same temps (mid to high 80s) and in a serious stress test with the highest settings I can hit ~93C maybe a bit more if I let it go on. For now I am not concerned as hitting higher 80s is not a big deal and I just tested it in CoH for about 30 mins and I didn't go over 87C which is fine in my books. I will keep this BIOS and play some more intensive games and post back later. If anyone ends up reading this please discuss!

Here are my temp findings and they make no sense:

530-1325-800 1.05v 92C

585-1450-850 1.05v 92C

600-1500-800 1.11v 93C

 

I'm on 1.15v and no problem

I'd guess the software running in DOS can't see beyond 640K or 1MB of RAM, one of those barriers..

 

Weird....i only get 9050 with 600-1500-800

 

Did you people ran 3dmark06 at default rez??

cause i tried to run it at 1366*768 and i got 9840 points!
because some people have the 16:9 screen version

can anyone who did the bios flashing and tests confirm the rez they used??

peace...

 

ahmed are you in vista64bit?? i got 9k in that as well.

Exostenza, i am exactly the same as the temps that you have posted. changing it to a GTS does naff all to the temps... seems to be the same vid card just underclocked. its been good fun oc'ing as well. and takes only a few mins once you have nflash, nvbitor.

This is funny. When I started this thread I thought no one seemed to care for it as one didn’t exist and the notebook had been out for a while and in such a short time we have come so far. This is great!

Anyway I myself have not have much time to try any of this but am getting ready to soon.

It seems some people have issues with the voltage bump and others cant run at the GTS speed without problems also.

I wonder if it would run @ the GTS speeds with less than GTS voltage but better than the stock voltage? We all know the lower voltage the more life to get out of it, (well in most cases as you can stress parts from under voltage also)

Has anyone messed around with doing that? GTS without GTS voltages but more than the 1.05?

One thing to keep in mind is maybe it does not need the full GTS voltage as they are somewhat different. For example doesn't the GTS have 1GB ram? The question would be is their more chips or just bigger density ones. As less chips can cause it to need less power

 

Bryanu: the way it seems to me is that you can either have 1.05v or 1.11v, but nothing in between according to nibitor as I thought about that already and checked it out. If someone knows otherwise let me know. Also the voltage bump doesn't change the temps even 1C so really I dont think it matters.

Betc: I see that you have the shaders and RAM bumped up from the GTS speeds which is nice to see... I was wondering if you had a chance to play with the core or could you not go over 600? Also at those clocks do you get the same temperature and you are 100 percent stable? I will play around with my 9800 more when I get a chance in the next couple of days.

Also can't remeber who it was, but someone on the last page said they were runing their card at 1.15v and I was wondering if it changed the temps at all or are they still the same as stock temps? This OC experience is very good' I am loving it!

 

I would just assume leave the memory clocks alone. Memory clocking always has the least effect on preformance I think but its also always the most common thing to fail on anything. Be it video or computer RAM. I rather not push the luck and kill it on the video.

Even though it may run stable who knows how much life will be taken away doing that.

Now with processors. I have NEVER seen one go bad unless it was user error or just bad from the get go. Just like on a PC. Only time I ever see or hear of a bad CPU is if either the FAN didnt work and it fried, or to much voltage.

So I assume same holds for a GPU as they are a little similar... Now I dont know how shaders work so cant comment on them but I myself will just stick with the clocking of GPU/Shadder. More so rather have GPU up as its safest to over clock but I think shaders give best results?

If this was a desktop I wouldnt care as much but being a notebook parts cost more, and are more a paint o repair/replace.

Desktop all my parts have lifetime warranty except my shi*y Asus Striker Extreme that has been in RMA for 3 months.. that only has 3 years...

But that being said I wont ever buy another Asus board and I have used them for business and home for 15+ years. EVGA here I come! Only wish they made notebook!


Anyway, I see at one point you had 585-1450-850 1.05v, have you tried to go higher keeping the stock voltage? I wonder how far we can push without volt change? memory also bugs out the most I think with voltage so if you start to see it going nuts drop down to 800 again? if that dont help than it could prob stay @ 850.

 

The way I see it is if the temps dont change what so ever with the c\voltage increase and the 9800m GTS has these clocks with the 1.11v it is probably needed for the best stability. I am not interested in seeing if it works at the lower voltages as really I see no point plus I hardly have any time to mess around with these things any more. I will however try to push it furthers with the 1.11v on. I do seem to remeber I had some problems with going higher than those clocks on 1.05v, but I cant remeber if it was core, shader and I can tell you the mem was having problems.

Anyways back to work...

 

I need to change the 2d clocks as when mine downclocks to that sometimes the screen does not refresh correct.

I think only the official nvidia drivers allow it to throttle down this low but it sure helps battery.

Anyway I want to bump them a tad but not sure what the steppings are. Is their a guid or something?

 

Well this sucks,

My first time playing with this one. (I have done my desktop card before)

Anyway I set volt to 1.11 and GTS speeds. All seemed OKAY than started to play a game and after a few min it had gotten to 83c which is still fine, but than got the display driver has stopped working error... Guess my card cant handle GTS speed

Now I got to figure out if the shader is the killer or core. I never get the good luck, lol. Here I am in hopes I can get GTS and figure I will leave it at that and not o/c it anymore and nope, not even can I do it.

**UPDATE 1**
Well I tried 585 1450 800 @ 1.05v and same thing...

So guess I got a lot more playing to do.

**Update 2**

Tried 570 1450 800 @ 1.05v and that seems much more stable... I have not done any longer tests but its better than the last 2 changes. Temp seems to max @ 85c which is funny thats more than my first try but maybe i just caught it at a good time. I do have a T9400 cpu though so it gets warmer... I am going for a P9600 in the next few months so that may help heat also.


On the memory are you all changing it to 800 or leaving at the 799? I changed mine to 800 but I cant see that being the issue?
