GPU clocks on these 7600's are quite pleasing on water.

Could complete 3Dmark06 at 780 Mhz on core at 1.58v, but going up to 1.65v only got me another 5 mhz - and artifacting at that.

Memory SUCKS, though. Even blasted with voltage it could only bench at 720-730 Mhz. Stock is 700.



Here's an 05 screenie.

There's no point in freezing this card. Even with a nice i7 and Gold Cup level GPU clocks, the crippled memory will prevent any significant benching.

I didn't do the fosc mod on the memory, but I'm pretty sure it won't be worth the effort involved when I have other more exciting things to bench.

Sigh...

Sorry to hear about the RAM Patch. Atleast you were able to gain a significant increase on the core, Nice!

looking good patch, let me know how the hwbot points play out so I can add that to the list

what brand are the vRam on the card, do you have their chip number, maybe the would run better with reverse vmem mod?
post #724 of 1336
some shots of Bastiaan's GTX275...input caps are landed..output caps are still drying before solder..and I got to nail down the vmeasure still...then test..then VR's go in



input caps for vmem phases


input caps for gpuv phases
post #725 of 1336
What kind of cabling is that you're using for those caps?

for the output caps, I am using a thicker gauge ribbon cable..input caps just have heat shrink over the legs.

*was going to land the output caps direct, but this card has to ship overseas...doing them like this helps keep them nice and secure..the connections are safer too. Liquid tapes finally dry..[just checked]..more pics later on this week..I got a beacon job for the first part of this week...260' tower needs a new lighting system on the top...so I'll be busy until Wed

Well the 96GT that was artifacting the other day seems to be running fine today.

Ran ATitool, no artifacts. Now she's folding, no EUE's.


As far as the switching goes. I might be wrong, you are not actually changing the freq. You are changing the limitation of the freq. So you are not setting it to 300Khz, you are allowing the power signal to run at 300Khz if it's needed. If that is true, you could just simply short the connect and allow max Khz. I saw another data sheet that refered to the connection being bridged to pretty much disable OCP.

^^This seems very plausible...and makes a lot of sense as to why some seitching mods seem to woek well and others dont...
post #729 of 1336
Definitely worth investigating. How did you come to that conclusion Pizza?

It hit me when I was reading the datasheet MadMaxx posted.
