Just to let you know I have just finished setting up the build.
It too me a total of 16 hours to sort out all the problems with my watercooling system. The last time I extensively routed the pipes was 5 years back, when I last upgraded my CPU, so I had to make quite a lot of changes. And after 10 years of their initial installation, some of the pipes are beginning to decay.
My room is in a complete mess right now, but I am going to be inching up with the clock speed until prime 95 throws an error.
For the record, after 5 minutes, the temp is at 45C, 100% CPU load, VCore (default): 1.224v, 3.6Ghz (only changed the multiplier in the BIOS, nothing else).
What sort of vcore do most people recommend for a 2600K, overclock, for 24/7 stable running?
EDIT: now at 4.0Ghz, default voltage (1.296v), current temp (while running prime95): 51C.
EDIT: now at 4.1Ghz, default voltage (1.308v), current temp (while running prime95): 51C.
EDIT: now at 4.2Ghz, default voltage (1.308v), current temp (while running prime95): 54C. (Also ran my computer at 4.2Ghz, the whole day, for "normal" work duties - totally stable)
EDIT: now at 4.3Ghz, default voltage (1.320v), current temp (while running prime95): 56C.
EDIT: now at 4.3Ghz, normal voltage showing as 1.272v in cpuz@100% load (-0.04v dynamic vcore, llc: high), current temp (while running prime95): 55C.
EDIT: now at 4.4Ghz, normal voltage showing as 1.308v in cpuz@100% load (-0.075v dynamic vcore, llc: high), current temp (while running prime95): 60C.
EDIT: now at 4.5Ghz, normal voltage showing as 1.344v in cpuz@100% load (-0.04v dynamic vcore, llc: high), current temp (while running prime95): 60C.
At this I am going to stop, as I don't particularly need a PC which is much faster.
@1.4VCore, I should be able to hit around 4.6Ghz-4.7Ghz.
In summary, the latest silicon will give you around the 4.6Ghz mark and you shouldn't automatically assume that you will hit 5Ghz on a new SB (without very high VCore).
Another forum member recently bought a 2700K (from ocuk) and hit around 4.8Ghz with it, so it is reasonable to expect the 4.6Ghz-4.8Ghz mark.
I hope this helps anybody thinking about buying a new IB or SB.
