, the problem im having is that i can get it 100% stable @ 3.7 with voltage @ 1.35 but if i try to get higher than this i blue screen and it doesnt matter how high/ low i set the voltages or adjust nb frequency, ram, ht it just wont have it, heres a little info on the hardware im using,
955 c2, 4gb corsair 1600mhz, 4870x2, the gpu and cpu or both watercooled and the board has 5 120mm fans blowing across it from the rads ,so heat is not a problem,
im running windows 7 ultimate 64 and have flashed to bios 1.6.
any help would be much appreciated.
Hi, ezgonzo, welcome...
It would very helpful to all of us if you could put in your system specs in your sig.
As to your issues, I can tell you the IMC (integrated memory controller) of these chips is limiting. The rated speeds for these chips is 1333Mhz on the memory, anything more is considered overclocking the memory, regardless of what the memory is rated for (1333Mhz, 1600Mhz, 1866Mhz, etc...).
Try lowering your memory clocks to 1066 and reasonable (loose) timings (you're not expected to keep it there forever), and then retry your clocking, when you have the speeds you want, write down your settings (these will be for reference later on).
Then back your CPU and NB down to stock speeds and start working ONLY
the ram up a little at a time. Find what it needs to run at rated speeds (1600Mhz & the rated timings), you will likely have to add volts to the ram (I run about .1-.15 extra volts to get stability with memory clocks over 1333Mhz).
Once you have the memory stable at it's speeds, then start adding a little NB only, get it stable, work it up, and then move on to adding in your CPU clock. It's a bit time consuming, but it is the best way to get stability.
And, try to avoid jumping around with different clock tests, these chipsets don't seem to like that very much. It seems we are all having some issues with this, of one kind or another.
So, lower the ram, clock the NB and CPU, lower them to stock, clock the ram, add in the NB then add in the CPU, and leave it and play your games and do your stuff!
Good luck, and make sure you add your system specs into your profile, it helps us significantly. Who knows, maybe I just gave you all the wrong info!
<-- j/k, of course!
