9600gt Crysis benches

[ades]

So, I will admit I am a little new to overclocking graphics cards, but I have been messing around with ocing cpus and ram, etc for many years now.

So to start my system:
e6600 running at 3ghz
Intel D975xbx Bad-Axe mobo
2gigs of ram (unsure of the clocks right now)
EVGA 9600gt KO

Running the Crysis Benchmarking program I found (search google) and the "benchmark_gpu" timedemo, here are some early results:

1280x1024 no AA, all settings high
stock 700/1773/950 memory : 30.84 fps
med 730/1800/1000 memory : 32.46 fps
high core 765/1773/950 memory : 31.91 fps

I have been having problems with the card freezing at 770+... any tips on getting it higher? I read someone on here had their card up to 820.

put more mhz on the shader or mem for performance in your case..., if you need more core (which isn't giving you better performance btw) you need more gpu voltage - that also gives you more head room on the linked/unlinked shader mhz. I think its 1.225 vGPU max and over-volt protection kicks in at 1.3volts. theres two ways to get more volts to the gpu (which allows more mhz), which are both dangerous: use a soldering iron to wire voltage regulators to the vchips, and mem ic's, or flash the bios to a SSC or OC edition of the card. google 9600gt volt-mod for more info.
*be careful it's dangerous!*

Hey now, getting me killed isn't cool, man! haha. I'm not planning on physical modification of anything.

I thought my earlier probs. were due to the memory, but now I see it was the core clock, so I'm still in the process of stability testing some higher mem./shaders. How high can they go? I am being very cautious, but I saw a site that had a card at 1045 memory, so I don't think I have much further to really go there. And I have no clue how high the shader can go.

 

[Tempered81]

they are going about as high as they will go with standard voltage on the GPU. You've already overclocked the hell out of it.

the next step is more volts - is the 820 u quoted on a stock version of the card?

 

[ades]

Good question, and I'm not sure. If this is "overclocked the hell out of it" then I am disappointed, to be honest. I tried to oc my 9800xt years ago, and it never made much of a difference, then I tried on my 7800gtx and that wasn't much of a difference either... At least with CPUs and such, you can get huge gains...

 

[Tempered81]

Well here is an extremely high clocked 9600gt:

"I just made an experiment.
In idle i lowered frequencies to around 600/1400/1600. Then i launched atitool artifact scanner and started scanning. While scanning i upped the voltage to 1.18v - no blank-out. I started raising core freq all the way up to 840. No blank out - no artifacts. Next i raised memory to 1160 - all well. Then i started upping shader - i think i got to 1600mhz when card shut itself off. After the black screen i measured the vgpu it was 1.045V. So to conclude this is very unlikely OVP. Looks more like OCP what do you think?"

I remember my 8800gt G92 would top out around about 720 to 730 on the core, 1780-1800 on the shader and 950-965 (~1930) on the memory. This also had 1.15v under load, it was a "bfg OC edition"

 

[happy medium]

Try a diffrent game. It will show better results then Crysis.

 

[ades]

Can you change the voltage through the PCI like you can for RAM?

Oh and I read that thread and it frightened me, lol. Are those guys all electrical engineers?? I'm back in school, so a $200 video card is worth a lot to me since I don't have an endless stream of money anymore.

I guess I should look at the fact that the refence card was clocked a bit lower too, in that regard, my clocks are well over stock. That does make me feel a little better

 

[manimal]

I was able to get 820 on the core and backed it off to a neat 800 for everyday use. I got the BFG OC card for about 170 at BB with coupons. Some cards OC better than others and while some may not agree with my tactics I have been known to cherry pick parts, ie return em till I get a good clocker. That limits me to B&M and with a frys and lost of stuff near me I usually pay a bit more than online for this reason alone. Now I got lucky with my 9600gt but I had to return my G92GTS 3x to frys because the first three were overheating at stock....let alone overclocked. With my overclocks I got about 1.5K increase in 3dmark06 but only a few FPS in crysis benchies. Now the CPU 2 benchmark did improve more than the other time demos and lowest FPS in all of them improved so the OC may seem small in average FPS but the the big slowdowns are what kills performance in crysis.

Looking at my results the trend of shader performance seems to be inline with what others have been saying for some time, while core speed is important on this card as in most 8 series cards overclocking the shaders and the memory seems to have a bigger benefit. As time goes by I may explore a softmod for this card or see if another bios helps but for a budget card this thing screams for my secondary machine. I may get another for SLI when the local BB has more in stock, they dispapeared off the shelves.

 

[Tempered81]

good point manimal. I know that with the bfg Oc editions of the 8800gts, they came pre programmed via BIOS to run at the highest allowed Vgpu voltage. (1.15 i think)

so the other brands and regular editions would run at 1.05 or 1.10, and wouldn't overclock nearly as high. My core could do 730 when a lot of people had problems at 675. I believe when manimal says his bfg oc edition can maintain a very high core clock.

no you can't increase the voltage to the card through your pci-e bus, it has to be regualted by the cards BIOS. the only options, albeit dangers, that you have is to flash to an SSC, ULTRA, OC edition type bios. this is called a BIOS v-mod.

 

[ades]

Dangerous how? Couldn't you re-flash it if shit hit the fan?

you unplug the power before doing such physical modification.

ummm... !!!!

 

[SniperDaws]

The max Stable i can get on my stock 9600GT is 760/1900/2100

i get 12995 on 3Dmark 06 with my cpu overclocked to 3.2Ghz.


im well impressed at that for an overclock from stock of 650/1625/1800.

my original score with everything at defaults is just over 10000.

 

[manimal]

Nice shader and ram OC on your card sniper.

 

[Tempered81]

yeah @sniper thats a huge OC. 9600 = g92 @ 64sp, 8800gt = g92 @ 112sp, and 8800gts = g92 @ 128sp. from there its all about how high you can clock your core/shader/mem.

@ades... that bios mod is dangerous because you can't always "just flash back incase of an error" if you permanently screw something up. there have been plenty of occasions where someone had a bad expereince flashing a bios/ cards mobos etc. Bios flashing is always dangerous, but if you're ballsy enough and want that extra mhz, it can be done. Google 8800gt bios mod.

 

[ades]

I had some time to mess with it today and it was running 100% stable during crysis at 770/1800/2060.

Just curious, if I scaled back the core, could i raise the memory a little bump more?

 

[Tempered81]

possibly.

you should notice more out of the shader clock in crysis.

Isnt the 9600 a G94?

 

[Tempered81]

oops ur right. wonder whats so different between a g94 & g92, since rollo says the SP's are identical.

Don't get me wrong, I'm not saying it's perfectly safe, but I've never seen a bad flash on a video card cause irreparable harm. You can flash the firmware to a working version blindly (I've set up batch files on boot disks for this) or use a PCI VGA to boot up with and flash the present zombie card. The bonus to vGPU modding is that it greatly affects shader clocks and not just core clocks.

True, i should have used this example:

you have a vanilla 8800GT at 600mhz core, manufactured by Inno3d or Galaxy. You find a bios that people in forums say is compatible with your card, yet the bios is made specifically for a Superclocked SSC 8800GT OC edition AC3 yada yada yada.

By flashing to this bios, you are accepting somewhat of a risk for attempting an operation that shouldn't be done, yet is possible.

I just flashed my laptop bios to dell A02, and my abit ip35E mainboard bios to 14Beta 5. Both of these processes went well just as Pliotronx described. Flashing is not difficult. Flashing for the purpose of gaining Vgpu can be risky. heheh.

If you dont want to flash it, you can edit it too Check out Nhibitor and NVflash.

 

[SniperDaws]

Jared can you increase voltages using NvFlash or is that a volt mod only ?

 

[Tempered81]

nvflash puts a newly "self authored" or home-made bios on your video card. It can also be used to flash to an official bios.

Nibitor is the program to write the bios.
