What are safe 24/7 overclocks for a 9800gtx? Also anyone that has one is the memory not very clockable? its supposedly rates at 1200mhz but good luck getting it there at least on this one.
 
starting to think i just got a crappy card. the core doesnt want to go past 770 using riva tuner and that seems low compared to what ive been seeing.
 
I got mine to 800/2000+/1150. I think i had near 2100 on the shaders, but i dont remember. I know it was definitely over 2000 though. My memory didnt OC for shit..50mhz total.

I would also like to note, the OC did pretty much nothing for extra FPS in games.

EDIT: That was with an Accelerso S1 with 2 120mm fans at low speed in a semi-well ventilated P182.
 
im running a turbo cool 860 from pc power and cooling and the card was at 78C so i dont think it was too hot.
 
how far off from the average am I? im hearing number literally all over the place some guys are running 850 im topped at 760.
 
Theres no gaurantees with OCing, but you generally really only hear about the really high ones. I think [H] review only got theirs up to 770 and 1975 on the shaders, but 2250 on the memory.
 
Well i redid the TIM and now im seeing it clock MUCH better currently at 774/1888/2200 and just working on overclocking the core at the moment. Im at about 76C with the fan control on auto since it doesnt seem custom fan profiles work with the 9800 yet. What is a safe max to run this thing at if it keeps going up well?
 
I am having the same problem, can't overclock it at all.. what is redoing the TIM?
 
Replacing the thermal compound on the chip. They tend to smear on the cheap crap from factory. If you replace it with as5 or mx-2 you can usually lower temps quite a bit.
 
Mine overclocked to the values in my sig (core/memory/shader). I increased each one individually by a reasonable amount, then tested for artifacts in ATiTool. Tried to find the max for each one, but didnt take much time to get those last few MHz out.

My memory didnt overclock for crap, but the core and shader overclocked a good amount.

Reguarding redoing the TIM, I dont think thats very worthwhile as these cards run pretty cool already. Mine idles at about 60C and under load (during gaming) it runs about 75C with the stock cooler. Did you see a big temp decrease after redoing it rennocneb?
 
Both of my new GTX's came in today. Hoping to hit at least 800. Why are your memory clocks so low. I thought it came with the memory stock clocked at 2200.
 
I had mine OC'd to 790/1190 core and ram. Stable for a solid week. However, as stated above, this didnt help much with gaming performance so I dropped them back down to stock.
