EVGA doesn't appear to have a TDP turbo limit, whereas for example the ASUS P6T (SE) does, and the P6T WS Pro has a setting for that in BIOS. From what I understand, you need to have C6 enabled to get the x23 multiplier for the X5650, that is, the maximal, uneven multiplier for a single core or possibly two cores. With C3 and lower, you only get the highest even multiplier, that is, x22 for the X5650.

Actually I have to say that the EVGA X58 SLI3 is a superior board to the P6T SE, despite the lack of many BIOS options and being seemingly simpler overall. Gives me visibly better results in BF4, for example, and Cinebench is slightly lower as well. Though overclocking RAM is easier on the P6T SE. For instance, I'm running 2000 8-8-9-24-2N at 1.6V right now, though it's not perfectly stable yet. There has been one lockup in BF4 so far, and I've deduced that to be caused by a RAM misconfiguraiton.

Downed QPI from 3710 (20x) to 3339(18x) and dropped VTT to 1.3V. Should I keep the QPI speed down or do I gain performance upping it?

So this is where I'm stuck at. When I try to enable turbo mode and get my 23x multi, I couldn't get it to even load into Windows (set it to 22x in BIOs and enable Turbo and it set it to 23x). I went as high as 1.35V on the VCore and it didn't want to boot. Anything I'm doing wrong? Here's where I'm at:



My QPI is now at ~3340 @ 1.3V VTT.

QPI is good, Where did your ram end up?
Your voltages are good, as long as it is stable and has decent temps.

Try using the 21 multiplier. You may be having a black hole phenomenon. My x5670 did not like 22X
My current chip hates 32X, but will scream along at 31, or 29.
go 21X 195 base clock. adjust accordingly for ram and QPI if needed. should be 4.179 core and 3510 QPI (18x) 3315 (17x) Should be able to leave voltages where you have them.
Run Prime 95 Large FFT (quick to show errors) or Intel burn test "high" see if is stable, and check temps.

Right now my temps are in the low 50s on Max Intel Burn Test. I'm currently on the 21x...guess I can up the BCLK. Right now my RAM is still what it was at 1863. You think just up the Vcore a bit and then my BCLK or should I also down the QPI again to verify that VTT is enough? I can also up VTT by 25mV to ensure it stays good?

post multiples of your CPU-z: CPU, Memory, SPD
list out the voltages you have currently.
We could try to get you higher, but i would try to find your max base clock. drop core, memory and QPI multipliers so they are very low. try to boot into windows at 205-210+ base clock. ?Doing this, we find out how high you may be able to go with the whole system. base clock determines everything now that we know your chip like 21x.

Then start to fine tune things like memory timings, QPI, and voltages. That memory you have is very capable.
Time to really start having fun. thumb.gif

@DRKreiger

here is imgur of what i'm using

The only thing that's changed from my BIOs shots from earlier is the VTT that's 1.3V now. I will try to boot with higher clocks here in a bit, but let me know what you think I should try!

@Punisher64 I think it's your ram screwing things up.. isolate the Cores - lower the memory, QPI, and Uncore.. there no way you should be failing at 3.9Ghz.

Guys, what do you think, if my X58 board is dead, and the only boards that I can get are all about $200; and then I also have a 3930K and the X79 boards are $200 as well.. should I sell the X5650 then and go X79? Or sell both and go X99, with a second-hand 5820K? My thoughts are that cheaper manycore Xeons may become available in the next few years, thus making the upgrade futureproof.

I don't fail at 3.9, that's what I'm running steady. When I turn on 22x multi and turbo mode (bringing it up to 23x) I can't get it to log into Windows with less than 1.35V and I didn't want to go over that to test.
