Installed and folding. Not fully setup for my gaming rig, but that doesn't happen til the watercooling kit shows up Friday. So what are yall experience for OC'in an FX. My system is ready to rumble! :smokin:
My stock scores pretty much rocked. Over 5K on the memory bandwidth stock with ECC turned on. I just need to learn the ins and outs of overclocking the FX-53. The rules seem totally different. :Pwned:
my dual 240 opterons hit 5500 on the sandra memory bandwidth with stock pc2100 ecc memory but there was 6 sticks of it. you can probably double your score with two more sticks. four sticks of pc2700 should hit almost 10,000.
So far I'm running 220FSB at 1.65V which comes out as a 2.7Ghz processor. Memory is happy at 2.7V. Sandra Memory bandwidth score increased to over 6200, and the cpu benchy scored over 11000.
I tried 225FSB and 230, but 230 caused system crashes and 225 caused a reboot 40% into a p212 for Folding@home. Upping the voltage for cpu and mem, and setting performance mode didn't help stabalize it. ECC is disabled.
Temps are around 109F with my watercooling rig. Which includes a Radeon 9800pro adding heat to the loop.
How hot does that chipset get? I have a better heatsink I could with a fan I could put on it. I'm thinking I am memory limited. What timings should I set for my Mushkin PC3200 reg?
I think I am multiplier locked. If I try to switch it away from 2400 (12) it defaults to 11 for multi and shows as 2.42Ghz. The FSB changes which I had as high as 235 showed strong improvement in the benchmarks, but were not stable in games or reboots. 220 x 12 seems to be my sweet spot. I only score 6200 on the mem benches. This was Sandra talkin, it may be lyin to me on the Ghz.
My memory doesn't have heat spreaders, but I don't feel it getting warm either. Any thoughts?
Watercooling temps are 105 - 109 under load. 105 is with the bleed and fill lines in the external reservoir (7-11 Double Gulp 64oz cup). 109 is with the loop closed. It came with 2 120mm Delta's for the radiator, but I haven't taken the time to notch the sides of the fans to allow for the rad screws to pass through. It came with a rheostat too, for obvious reasons.

also, its better if u OC using clockgen, Changing options in the bios will not always apply.
WATCH OUT for Performance mode (in jumperfree settings), it will boost ur vcore to the max (1.775v).
pm me if you need any help
Tex: i dont think that rule applies to single cpu 940's.

you need to pickup one of those 33/66mhz IDE/sata controllers or else you ill never be stable.
for some reason if i mem bench anything over 230, my bandwidth decreases to 6.4gb/sec, it might need more voltage.
at 230 i hit around 6.6-6.5gb/sec
you asked about mem timings, the ram that you have is awesome, it should handle tight timings @ 230
FX's are not locked, i get the same result OCing from the bios.
have u installed that 66mhz card yet?
whats ur Vdimm@ u need to max that.
what videocard are u using? if it ATI, u need to lower ur agp to 4X to run games at 230FSB.

Where do I get clockgen. I'll look for it later after I get home.
Memory voltage is at 2.8v, cpu is at 1.75
heres also a nice thread for Ocing sk8v
