What is your highest overclock?

[aussiejunior]

cpu @ 4.25ghz the 9600's @ 770 core 1750 shader and 1003 mem I was able to get a score of 18639 in 3dmark06.

cpu e8500
mobo xfx 790i ultra
ram ocz ddr3 @ 2000mhz 9,9,9,24,2t

MB unkown.
Award BIOS

Before:
PIII 550 MHZ
PC100/33
multiplier: 5.5

After:
PIII 1.06 GHZ
PC133/44
multiplier: 8.0 *Make that 9.5. Same speed though.

Now, I'm not comftorable with it that high, so it's at 816 (ish) MHZ

While that may be a nice result, AmEv, how stable is the system?
The PCI bus is already at max, 33 Mhz.. so upping its bus speed may cause data errors. And if there is an ISA bus, that also has a limit. Same if there is an AGP video slot.. 66 Mhz. The CPU has internal cache memory, which is more affected by higher speeds than the core itself. The main memory in the system also must be capable of accurate paging at higher speeds. If using PC133 memory, you may have good results at that speed.. but PC100 would stumble all over itself!

Ah... THAT explains why System Monitor was having it constantly at or near 100%.

(at least I wasn't using PC66)

My highest overclock is pretty weak but I feel that is was good for me.

Specs

And 1 old school Floppy Disc Drive (I know very old school but I felt like puiting it in just for the sake of it)

I now have a Q8400 instead of an E6500 so now i notice less lag in games but I haven't experimented in overclocking it yet I'll post later when I start overclocking it but I might need some assistance and some tips on overclocking it.
