memory timing bios mod?

 

[Solaris17]

modify the timings of the ram in the bios of the card.

 

[Scrizz]

all the love going round and none for me?

 

[Solaris17]

whatya need scrizz?

9600gt

Did some benching, this is what I ended up with:

E6750 @ 3.44 Ghz
9600Gt 828/1067/2070 ... idle 44C full load 64C (so far)
12122 3dmarks

getting better...

air cooling...but it's in the basement.

 

[Solaris17]

w0ot!!! its great stuff isnt it? the card is actually pretty powerfull considering other highend cards.

 

[Skitzo]

wow

I just looked at wolf's clocks again...wow! I had a feeling that the alpha dog would oc a little past the other gt's. Woohoo

 

[Skitzo]

.

yes yes yes ... I'm impressed.

 

[Skitzo]

a little more

I think I could push it a little more seeing as I was testing and benching with dual monitors except for the last bench.

Hey Wolf, Your 8800 better pick up the pace, a volt mod (is there one?) could see my 9600 closing the gap even more.

 

[Solaris17]

pssst "8500/8600/GT/GTS mod guide"

 

[Skitzo]

I forget myself sometimes...

got it...

 

[Solaris17]

take a look at this pic, are these burns from my oc or manufacturing?




edit: I see a scratch and burnt component aswell: see zoom pic

i dont think those are burn marks but instead i think it was a spill....your supposed to put down this resin stuff b4 you solder a resistor the the board and then you clean it up..it simply looks like the machine squirted out to much and it just dried to the pcb

 

[Skitzo]

...

Good to know, gotta decide what to do with it.

 

[wolf]

for some reason my 8800Gt wont boot in any system with the quad core overclocked, it always makes it screw up and revert to 2.4ghz, thus my 9600GT is currently my fastest card, which is weird cos my 8800GT is 800/2000/1900 and with the quad at 3.6 should be looking at near 15k 3dmakrs. any ideas on why a mobo oc is sensitive to a gfx card sol?

PCI-E freq? try clearing the cmos and then putting the card in and trying agian..also check you power cables make sure your putting them in the same order and not mixing them up the 8800 requires mroe power so you may be getting the low voltage blackout.

 

[Scrizz]

yeah I'd say check the pcie freq, it can cause the system to not boot.
make sure it's not set on auto

 

[wolf]

its just so weird cos if the mobo is at stock settings (2.4ghz) then its all fine, its only after i start to overclock that it reboots at post.

 

[Solaris17]

voltage instability? hmmyou have all that intel speed step eist stuff off right?

 

[wolf]

absolutly, its a very confusing conundrum, i really wanna bench that vmodded 8800GT with the quad running so fast!

 

[wolf]

modify the timings of the ram in the bios of the card.

assuming that our cards share the same vmem, what timings should i use, im aiming for 2200mhz effective.

 

[Scrizz]

Hey Wolf, you could send the 8800gt to me for further testing

 

[wolf]

depends what your sending me as a swap

 

[Skitzo]

...

I'll send you my 8600GT with a V2 ... but wait, it's cool cause it's got tattoos. No volt mod yet but I thought about it lots so that should be worth something... And don't forget, she's famous ... she's got pics on the internet. oh yeah it runs at 770/905...should do well with a v-mod.
