TiZoRs 8800 series overclocking/flashing guide

[J.D]

Ach not at all Will . I'm cool. Hope you are too?. Sorry if I've ****** you off as well. No hard feelings.

A good thing has come of it though. Now anyone trying this will know that if it's flashed and breaks that it will be much harder to RMA .

The OP goes to the trouble of posting a guide to flashing and you say there is no point.

Why post then?

There was a point to the OP or he wouldn't have done it.

Was there no point in hundreds of people flsahing their 9800 PROS to XT's either ,that had R360 cores?

There is no denying that its a well presented guide but apart from getting round the OPs Vista issue i personally wouldnt flash as i cant see any benifit, unlike the 9800 pro to xt which allowed those with the R360 core to increase their clock speeds. A hardware OC wouldnt allow my core speed to drop during idle as it does under ATI Tool.
Isnt the point of these forums the passage of information and the ability to debate?

Another reason for flashing, would be you can overclock your shader clocks higher, you cant do this with software clocking, and when people reach the core limit i belive the shader clocks can go higher, with more performance gain.

Is that a fact or a belief, i didnt think the the core and shader clocks were indipendantly changable.

So your bios has other tweaks like higher shader clock etc..?

 

[J.D]

Does the new Nvidia driver (might be beta) not do something to shader clocks as to make them overclock independently now?. And is there a program out to do this yet?.

I'm sure a few users Core and Memory overclocks stayed the same but the shaders went back to stock.

Correct me if I'm wrong but isn't doing this quite risky? I know that my card behaves differently depending on the outside conditions - in the summer I have to reduce the overclock from what I know to be the max because otherwise I'll get tearing (just a factor of the increased ambient temps).

If you flashed a card to its absolute max clock then you're going to run into problems when the weather gets hotter, arent you?

 

[Locky]

Well, overclocking is risky anyway, but i advise you have better cooling or using fan controll to 80%, its up to you what clocks you set, i advice 621core/1458shader & 900mem which is 1800ddr, this has been good for both 8800GTS cards ive tried with default cooling.

gunna look into a bios mod for setting the fan speed to 80% by default.


PS. I advise you dont overclock your card if your cooling is poor in your case or getting high temps on your gfx at stock

my 8800 doesnt go over 67oC.

You don't need to boot to DOS using the floppy to backup the BIOS - in NIBITOR you can go to tool>select device /// then tools > read to file and save the BIOS directly to a .rom file, then simply copy the rom file and call it a new name and modify the clocks in nibitor using that.

THEN! put the modified bios onto floppy and flash in DOS

I don't have a spare floppy else I'd have done it now and no DOS bootcd seems to detect my DVDRW drive in DOS for some reason!

ah didnt know that, cheers

The 8800 Does have 2D clocks, by default both 2D and 3D are same speed, just use Rivatuner to make 2D slower, I certainally do not want or need my Core at 700mhz to surf the WEB or type a Word .DOC.

You can go as low as 330mhz in Rivatuner with a Ultra, if you want lower you need flash mod and reflash the Bios.

 

[bfar]

I've always flashed a new bios once I found my optimal overclock. Means you don't have to install rivatuner again.

YOU REALLY NEED TO KNOW WHAT YOU ARE DOING.

Tbh I've had no reason to overclock my stock gtx so far, it's a rocket as it is.
