Don't know if I'm talking trash, but moving to a higher speed CPU doesn't mean that the memory handling part will allow faster memory speed. These CPUs are officially rated for memory speeds up to 1333 MHz. It sounds like you got lucky with your first chip supporting 1886 Mhz! I've got memory rated for 1886 Mhz, but I can't even get it to run at 1600 MHz reliably.

Yeah I'm starting to think that the IMC just isn't that good on my X5675. However, I think overall it still is better considering these options I have:

X5650: 188x22 = 4.14 GHz @ 1.4 V, 1866 MHz RAM, C-states enabled
X5650: 195x22 = 4.3 GHz @ 1.4 V, 1560 MHz RAM, C-states disabled
X5675: 200x22 = 4.4 GHz @ 1.375 V, 1600 MHz RAM, C-states enabled

I might be able to go below 1.375 V for 4.4 GHz but I know 1.35 V crashed on an overnight run. Funnily enough, the RAM seems stable at 1600 MHz on "auto" settings, which uses tighter timings than the sticks are rated for...

Yes, that X5675 looks the best of the three chips you have. Memory speed and timing, and how many sticks you have, it really hit and miss on the X58 platform.

Wondering has anyone upgraded to Win 10 1803 yet, I am getting the Windows logo on boot up after the initial install, seems like there may be an issue with the x58 chipset and 1803 according to some postings on the net.

Apparently disabling VT-d allows it to work, but I do not want to do that as I use my machine for VM's

Could this be the start of the end?

Can anyone else verify this?

Thanks

I upgraded on day one and it's all working fine here.

No problems here with 1803.

There's no 'chipset issue'. If you're doing a fresh install and disabling vt-d makes it work then it's probably the core isolation feature of windows defender.

Been doing a little more digging, it appears it may be on some Asus boards only. For example I am running the Asus PT6D.

Hopefully some more detail will come out soon.

You should be good with 205x22, ran that for a couple of years here

I'm actually at just over 1.4 V with 200x22 right now. Although 1.375 V was stable for stress testing, it wasn't in gaming annoyingly. So I don't really wanna push any much higher when temperatures are already low 60s when gaming.

Can anyone suggest a good place to get a X5650 from?

would like to give one of these ago and replace my I7 950

As the chap above has suggested, 'The auction site' is the best place. I got mine from there, was up at £22 or best offer, so offered £18 including delivery. Amazing price considering the mileage still left in these things!
