Overclocked 512mb Geforce Go 7400

WELL IM NEW HERE, FIRST POST!! YAY well it all started when I bought my new lappy and it came with my beloved 7400 with 512mb then I updated my drivers and my 7400 said it had 256 weird, I started searching for the answer 2 my problem i found out that it was the bios, so i reinstalled the older bios, then i started looking for the right drivers for my 7400 I ended up installing the original factory drivers, i also installed nforce and found out i could OC my baby... SWEET i said... lets give it a try... I downloaded a few tools 2 monitor my temps. and oc'ed the gpus frequencies with the autodetect feature when I found out it went up 2 516 mhz/836mhz i was suprised everything works like a charm and games, well they run GREAT!!!

I dont know if this has been done bfore... if it has pls commet maybe u can give me some pointers...

 

What is your notebook model ? A Go7400 with 512MB of ram , that is definitely an overkill for a Go 7400, I mean there a plenty of 7600s and even 7900GS s with 256MB.

I'm not trying to burst your bubble, but a Go 7400 is not exactly a gaming card, and I really don't think overcloking it would give you a huge performance increase

If your notebook is a 12” or a 13.3” then I strongly advice against overcloking due to cooling issues.

 

my notebook is a dv8275la its only available at the latin american market.

 

Ok, from the specs it is a 17”. So you won't have that many heat problems like I said before. But still keep an eye on your temps.

Can you please post your results, before and after overclocking ? maybe some game benchmarks or 3D marks ?

 

im currently downloading 3dmark to c how i do, (since im a noob ) but my temps havent gone up that much I've been constatly cheking them when the gpu was stock the temps wø░ around 39-40°C they currently are at 41-43°C

what do you think?

 

Those temps are quite good for an overclock (I've seen much higher temps at stock speeds with faster cards). BTW what was the stock core/mem ?

 

the stock core/mem was 450/700mhz

Check this image of my desktop it has all the info i have so far

3dmark scores COMING SOON...

 

you can OC your 7400 even more. my highest clock speed is currently core/mem(531/1060)

 

i will try it hope i dont fry it

 

Wow! Do you have GDDR3 vram, don't you?

 

It's really unlikely that DDR2 vram installed on laptop goes so high. I've never seen DDR2 mobile cards go higher than 940-960MHz.

 

you don't have 512mb gpu you have a 256mb gpu with some crappy turbocache vram.. 7400 definitely do not come with 512mb.. overclocking = teh ****

 

The GeForce Go7400 does not have more than 128MB of dedicated memory - period. Yours is 128MB dedicated + 384MB shared via TurboCache.

That's a nice overclock though, do you have any 3DMark scores for us? It'd be cool to see a before/after.

 

must be, because my x1600 barely goes above 400mhz because its GDDR2.

 

Well, with my X1600 I get artifacts over 468MHz (936MHz real). It's strange that you can't go over that frequency. You should go easily over 450MHz (900MHz)...

i think your card only has 256

 

well... i cant post the 3dmark results yet.. its taking 4ever 2 download it... but ill have them ASAP, right now im at 530/877 and i think thats all i can get out of it.

 

hello all... Ive finally installed 3dmark06 I really dont know how to use it so I just clicked Start Test and my resuts were 957

 

XPS M1210 with a a Go 7400 256MB Turbocache (64dedicated 196shared) scores around 800 3Dmark06 points. 957 is roughly about 20% increase. I'd say that is a good overclock. I think you can easily surpass X1400 performance level with yours.

 

Probably not.

 

Is it possible to get over 1000Mhz with GDDR2 memory? Seems not.
I assume you're getting doubled clocks (DDR) on screen, so it's really between 400-500Mhz.
That score is pretty good for a 7400 though...congratulations gpu_maniac.
By the way...where are you from?

 

huge score for a X1400!
what are the clock speeds? is the laptop a lenovo?

 

Thanks By Tor Im from Guatemala Central America, even the 7400 has its limits im pretty happy with mine, im playing most of the games smoothly and with a great video quality. but I really feel the need of upgrading so I might get a new notebook soon, Im, that 20 inch sager its a big temptation

 

Any laptop with a 7900 nVidia or above will serve you more than well, 7400s are not good enough for newest games. That Sager is really tempating if you are willing to pay the price ($,battery,heat)....if you have money to burn there are SLI (dual cards) options around from Alienware and others.
Also consider the 512MB 7600s, ASUS has some good options there.
Good luck.
I am from Chile but living in México right now, estamos en un foro muy internacional!!!

 

That's all you have to do to be honest. That sounds like a decent score for a Go7400 to me.
